Answer:
See below
Step-by-step explanation:
1. C = 2(3.14) for r
r = C / 3.28
2. A = 1/2 b h for b
b = A2 / h
3. y = Mx + b for x
y - b = Mx
x = (y - b) / M
4. A = 1/2 (a + b) h for h
A = (1/2a + 1/2b)h
A = 1/2ah + 1/2bh
A = (a + b) h / 2
h = 2A / (a + b)
5. V = (3.14) r² h for h
h = V / (3.14 r²)

Noah buys 3 packages of pens. Each package has 4 blue pens and 2 black pens.
Which equation can be used to find p, the total number of pens?
3 x (4+2) =p
3 X 4 X 2 =p
3+ (4 x 2) =P
3 +4+2 =p
Answer:
A
Step-by-step explanation:
So he bought 3 packages of pens.
And each package has 4 blue and 2 black.
Thus, the equation that can be used to find the total number of pens p is:
[tex]3\times(4+2)=p[/tex]
The (4+2) represents the total number of pens in 1 package. And the 3 represents the total number in 3 packages.
Further notes:
The total number of pens would be 18.
Answer:
3 times (4+2)=p
Step-by-step explanation
this is the answer because it gives us that key word and the key word is each and total and when you solve it the answer would be 18 because always use the parentheses first then add 4+2 and that equals 6 and times 6 with the 3 and that gives 18

Answer:
l = 58.5
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
112 = 2l - 5
Step 2: Isolate term l by adding 5 on both sides
117 = 2l
Step 3: Isolate l by dividing both sides by 2
117/2 = l
Step 4: Evaluate
l = 58.5
Answer:
[tex]\Large \boxed{l = \frac{117}{2}}[/tex]
Step-by-step explanation:
Let the length be [tex]l[/tex].
[tex]112 = 2 l - 5[/tex]

The table below shows the price in dollars for the number of roses indicated is the price proportional to the number of roses explain in 2 college sentence
Answer:
Price of roses is proportional to the number of roses.
Step-by-step explanation:
Let the price of roses are proportional to the number of roses.
Equation representing this phenomenon will be,
P = k(R) ⇒ k = [tex]\frac{P}{R}[/tex]
where 'P' = price of the roses
R = Number of roses
k = Proportionality constant
If we substitute the values of P and R and we get the same value of constant 'k', then the equation will be true.
For R = 3 and P = $9
k = [tex]\frac{9}{3}[/tex]
k = 3
For R = 6 and R = 18
k = [tex]\frac{18}{6}[/tex]
k = 3
K is same in both the conditions, therefore, Price of roses are proportional to the number of roses.

Bell metal which is a form of bronze is used for casting bells. It is an alloy of copper and tin. To make bell metal requires 17 parts of copper to every 3 parts of tin. (6) (i) Express this requirement as a ratio (ii) Express the amount of tin required as a percentage of the total (iii) If the total amount of tin in a particular casting is 150 kg, find the amount of copper
Answer:
you need 17 parts copper and 3 parts tin in order to make brass
1. ratio of copper with respect to brass: 17:20
ratio of tin with respect to brass: 3:20
ratio of tin with respect to copper: 3:17
2. percentage of tin required in brass: fraction of tin in brass X 100
3/20 X 100 = 15%
3. if we used 150 kg tin in the alloy, then 150 kg is 15 % of the alloy
(from last answer)
150/x X 100 = 15%
x = 1000 kg
if the total brass formed is 1000 kg, and 150 kg of it is tin,
copper used = 1000 - 150 = 850 kg copper

A. what is/ Are The value our values of the variable that make(s) the denominators zero?
x=
Answer:
A. -4 and 4
B. No solution.
Step-by-step explanation:
The given equation is
[tex]\dfrac{3}{x+4}+\dfrac{2}{x-4}=\dfrac{16}{(x+4)(x-4)}[/tex]
A.
Equate the denominators equal to 0 to find the restrictions on the variable.
[tex]x+4=0\Rightarrow x=-4[/tex]
[tex]x-4=0\Rightarrow x=4[/tex]
Therefore, [tex]x\neq -4,4[/tex].
B.
We have,
[tex]\dfrac{3}{x+4}+\dfrac{2}{x-4}=\dfrac{16}{(x+4)(x-4)}[/tex]
[tex]\dfrac{3(x-4)+2(x+4)}{(x+4)(x-4)}=\dfrac{16}{(x+4)(x-4)}[/tex]
Multiply both sides by (x-4)(x+4).
[tex]3x-12+2x+8=16[/tex]
[tex]5x-4=16[/tex]
Add 4 on both sides.
[tex]5x=16+4[/tex]
[tex]5x=20[/tex]
Divide both sides by 5.
[tex]x=4[/tex]
Here the solution is x=4 but it is the restricted value.
Therefore, the given equation has no solution.
For the given rational equation, we have that:
A. The values of the variable that make(s) the denominators zero are x = -4 and x = 4.B. The equation has no solution.Rational Equation:The rational equation given in this problem is:
[tex]\frac{3}{x + 4} + \frac{2}{x - 4} = \frac{16}{(x + 4)(x - 4)}[/tex]
Then, applying the least common factor:
[tex]\frac{3(x - 4) + 2(x + 4)}{(x + 4)(x - 4)} = \frac{16}{(x + 4)(x - 4)}[/tex]
[tex]\frac{5x - 4}{(x + 4)(x - 4)} - \frac{16}{(x + 4)(x - 4)} = 0[/tex]
[tex]\frac{5x - 20}{(x + 4)(x - 4)} = 0[/tex]
Item a:
The denominator cannot be zero, hence:
[tex](x + 4)(x - 4) \neq 0[/tex]
[tex]x \neq -4[/tex]
[tex]x \neq 4[/tex]
The values of the variable that make(s) the denominators zero are x = -4 and x = 4.
Item b:
[tex]5x - 20 = 0[/tex]
[tex]5x = 20[/tex]
[tex]x = \frac{20}{5}[/tex]
[tex]x = 4[/tex]
However, x = 4 makes the denominator zero, hence the equation has no solution.

Minstrel Manufacturing uses a job order costing system. During one month, Minstrel purchased $198,000 of raw materials on credit; issued materials to production of $195,000 of which $30,000 were indirect. Minstrel incurred a factory payroll of $150,000, of which $40,000 was indirect labor. Minstrel uses a predetermined overhead rate of 150% of direct labor cost. The total manufacturing costs added during the period is:
Answer:
$440,000
Step-by-step explanation:
Direct material:
= $195,000 - $30,000
= $165,000
Direct labor:
= $150,000 - $40,000
= $110,000
Manufacturing overhead:
150% of direct labor cost.
= $110,000 x 150 ÷ 100
= $16,500,000 ÷ 100
= $165,000
Total manufacturing costs:
= $165,000 + $110,000 + $165,000
= $275,000 + $165,000
= $440,000
The total manufacturing costs added during the period is: $440,000
Problem PageQuestion A circle has a radius of . Find the radian measure of the central angle that intercepts an arc of length . Do not round any intermediate computations, and round your answer to the nearest tenth
Answer:
0.1π radStep-by-step explanation:
The question is incomplete. Here is the complete question.
A circle has a radius of 19m . Find the radian measure of the central angle θ that intercepts an arc of length 5m. Do not round any intermediate computations, and round your answer to the nearest tenth.
The formula for calculating the length of an arc [tex]L = \frac{\theta}{360} * 2 \pi r[/tex]
θ is the central angle
r is the radius of the circle = 19m
L is the length of an arc = 5m
Substitute the given values into the formula and get the central angle θ
5 = θ/360 * 2(22/7)*19
5 = θ/2π * 119.4285714
θ/2π = 5/119.4285714
θ/2π = 0.041866
θ = 2π*0.041866
θ = 0.083732π
θ = 0.1π rad (to the nearest tenth)
Hence the radian measure of the central angle that intercepts an arc of length to the nearest tenth is 0.1π rad
The mean cost for a pint of frozen yogurt is $1.50, with a standard deviation of $0.10.
What is the value of the variance?
a.) $0.40
b.) $0.10
c.) $0.01
d.) $0.20
Answer:
The correct answer is:
0.01$ (c)
Step-by-step explanation:
Standard deviation is a measure of how spread out numbers are from the mean value. The formula for standard deviation is given by:
[tex]s = \sqrt{\frac{\sum(x - \bar x)}{n} } \\where:\\x = sample\ \\\bar x\ = mean\\n\ = number\ of\ samples\[/tex]
Variance is a measure of the squared differences from the mean.
Variance is simply the square of the standard deviation. It is mathematically shown as:
[tex]s^2 = \frac{\sum(x - \bar x)}{n} }[/tex]
Now in our example,
Stabnard deviation = $0.10
Variance = (standard deviation)²
Variance = (0.10)²
Variance = $0.01

Carl owns a company that washes the windows of office buildings. He recently signed a contract for a large office building and estimates that it would take 2 days for 4 workers to wash the windows. Write an equation to describe the relationship between time (t) and the number of workers (n), which are inversely proportional.
Answer:
t = 8 / n
Step-by-step explanation:
Time (t) and the number of workers (n), which are inversely proportional.
t = k (1/n)
t = k / n
Where,
t= time it will take workers to finish their job
n = number of workers doing the job
k = constant of proportionality
He estimates that it would take 2 days for 4 workers to wash the windows.
t= 2 days
n= 4 workers
t = k / n
2 = k / 4
Cross product
2*4 = k
8 = k
The relationship between time an number of workers is
t = k / n
t = 8 / n
Answer:
Step-by-step explanation:
t= 8/n
Solve the problem. A variable x has the possible observations shown below. Possible observations of x: -3 -1 0 1 1 2 4 4 5 Find the z-score corresponding to an observed value of x of 2.
Answer:
[tex]z = 0.228[/tex]
Step-by-step explanation:
Given
x: -3 -1 0 1 1 2 4 4 5
n = 9
Required
Determine the z-score x = 2
z score is calculated by
[tex]z = \frac{x - Mean}{SD}[/tex]
First, we need to calculate the mean
[tex]Mean = \frac{\sum x}{n}[/tex]
Mean = \frac{-3- 1 + 0 + 1 + 1 + 2 + 4 + 4 +5}{n}
[tex]Mean = \frac{13}{9}[/tex]
[tex]Mean = 1.44[/tex]
Next is to calculate the standard deviation
[tex]SD = \frac{\sum (x_i - Mean)^2}{n}[/tex]
[tex]SD =\sqrt{ \frac{(-3-1.44)^2+(-1-1.44)^2+(0-1.44)^2+(1-1.44)^2+(1-1.44)^2+(2-1.44)^2+(4-1.44)^2+(4-1.44)^2+(5-1.44)^2}{9}[/tex][tex]SD =\sqrt{ \frac{(-4.44)^2+(-2.44)^2+(-1.44)^2+(-0.44)^2+(-0.44)^2+(0.56)^2+(2.56)^2+(2.56)^2+(3.56)^2}{9}[/tex]
[tex]SD =\sqrt{ \frac{19.7136+5.9536+2.0736+0.1936+0.1936+0.3136+6.5536+6.5536+12.6736}{9}[/tex]
[tex]SD =\sqrt{ \frac{54.2224}{9}[/tex]
[tex]SD =\sqrt{6.02471111111}[/tex]
[tex]SD = 2.455[/tex]
Substitute these values in
[tex]z = \frac{x - Mean}{SD}[/tex]
Where x = 2
[tex]z = \frac{2 - 1.44}{2.455}[/tex]
[tex]z = \frac{0.56}{2.455}[/tex]
[tex]z = 0.228[/tex]
Hence, the z score of x = 2 is o.228

What is the common ratio of the geometric sequence below?
Answer:
The answer is option BStep-by-step explanation:
Since it's a geometric sequence, to find the common ratio divide the previous term by the next term.
That's
[tex] \frac{48}{ - 96} = - \frac{1}{2} [/tex]And also
[tex] \frac{ - 24}{48} = - \frac{1}{2} [/tex][tex] \frac{12}{ - 24} = - \frac{ 1}{2} [/tex]Also
[tex] \frac{ - 6}{12} = - \frac{1}{2} [/tex]Since the common ratio is the same for any of the terms chosen the common ratio of the sequence is
[tex] - \frac{1}{2} [/tex]Hope this helps you
Answer:
B. -1/2
Step-by-step explanation:
The common ratio is the ratio between two numbers next to each other To find the common ratio, divide a term by the preceding term.
For example, if the term is 48, divide by -96.
48/-96 = -1/2
Another example, if the term is -24, divide by 48.
-24/48= -1/2
Let’s try one more example. If the term is 12, divide by -24
12/-24= -1/2
Therefore, the common ratio is 1/2 and the correct answer is B.

Suppose that you roll two dice and don’t get to look at the outcome. Your friend looksat the outcome and tells you honestly that at least one of the dice came up 6. What isthe probability that the sum of your two dice is 8?
Answer:
2/11
Step-by-step explanation:
We have to calculate this by
p(B nA)/p(A)
= We have A¹ to be that none of the die roll gives us 6
P(A¹) = 5/6²
P(A) = 1 -5/6²
= 11/36
BnA = one die being 6 and summation being equal to 8
= BnA = (6,2)(2,6)
= P(BnA) = 2/36
Therefore we have (2/36)/(11/36)
= 2/11
The Department of Transportation would like to test the hypothesis that the average age of cars on the road is less than 10 years. A random sample of 50 cars had an average age of 9.5 years. It is believed that the population standard deviation for the age of cars is 3.4 years. The Department of Transportation would like to set = 0.10. The critical value for this hypothesis test would be ________.
Answer:
0.1492
Step-by-step explanation:
Mean (m) = 9.5
Standard deviation (sd) = 3.4
Number of observations (n) = 50
Computing the test statistic :
X = 10
Z = (x - m) / standard error
Standard Error = sd/sqrt(n)
Z = (x - m) / (sd/sqrt(n))
Z = (10 - 9.5) / (3.4/sqrt(50))
Z = 0.5 / 0.4808326
Z = 1.0398 = 1.04
Using a P-value calculator, we can obtain the critical value with α = 0.10, hence, the critical value = 0.14917
= 0.1492
