Answer:
$28
Step-by-step explanation:
The towel was $44 but at 1/2 off would be $22.
Her total cost was $38 so we subtract $22 from $38 to find how much she paid for the beach hat.
$38-$22 = $16
We add $12 to $16 to find the original price of the hat.
$16+$12 = $28
Answer:
$28

20 POINTS: If tan= 3/4, find the CSC I don't know the relationship between tan and csc, please explain your answer
Answer:
[tex]\csc(x)=5/3[/tex]
Step-by-step explanation:
So we know that:
[tex]\tan(x)=3/4[/tex]
Recall that tangent represents the side opposite over the side adjacent.
This means that the opposite side is 3 while the adjacent side is 4.
Therefore, by using the Pythagorean Theorem, we can solve for the third side, which is the hypotenuse:
[tex]a^2+b^2=c^2[/tex]
Substitute a for 3 and b for 4. Thus:
[tex]3^2+4^2=c^2[/tex]
Square and add:
[tex]9+16=c^2\\25=c^2[/tex]
Square root:
[tex]c=5[/tex]
Now, recall that cosecant is the reciprocal of sine. So, find sine first.
Sine is opposite over hypotenuse. From tangent, the opposite is 3 and the hypotenuse as we now know is 5. Thus:
[tex]\sin(x)=3/5[/tex]
And cosecant is the reciprocal of that. Thus:
[tex]\csc(x)=5/3[/tex]
And that's our answer :)
Find the value of n and YZ if Y is between X and Z.
XY = 5n, YZ = 2n, XZ = 91
The value of n and YZ are 13 and 26 respectively
If Y is between X and Z, then:
XY + YZ = XZ
Given the following
XY = 5n
YZ = 2n
XZ = 91
Substitute the given expressions into the formula as shown:
5n + 2n = 91
7n = 91
Divide both sides by 7
7n/7 = 91/7
n = 13
Get the measure of segment YZ
YZ = 2n
YZ = 2(13)
YZ = 26
Hence the value of n and YZ are 13 and 26 respectively

Which of the following circumstances would likely make completing the square th
best method for solving a quadratic equation?
The leading coefficient is 1 and the linear term coefficient is an even number
The leading coefficient is not 1 and the constant is large
The difference of 2 perfect squares
The difference of 2 perfect cubes
Answer:
The leading coefficient is 1 and the linear term coefficient is an even number
Step-by-step explanation:
Leading coefficient must be one for the application of completing square method. If the completing square is not one than we must apply other methods like Ac method, quadratic formula to solve the equation. To solve the equation with completing square the numerical value must be on other side of the equation. In this method we multiply linear term’s coefficient with one-half and square it therefore, completing square is suitable method for the equation having leading coefficient is 1 and linear coefficient is even.

A population of pea aphids double every week beginning with 300 aphids.
Week 1: 300 × 2 = 600
Week 2: 600 × 2 = 1200
Week 3: 1200 × 2 = 2400
Week 4: 2400 × 2 = 4800
Week 5: 4800 × 2 = 9600

Find the lowest number divisible by 15, 20 & 25.
Answer:
300.
Step-by-step explanation:
This is the LCM.
15 = 3 * 5
20 = 2 * 2 * 5
25 = 5 * 5
One 5 appears in all 3 factors so we only use this once in the calculation:
LCM = 2 * 2 * 3 * 5* 5 = 300

Between 10pm and 7:45am, the water level in a swimming pool decreased by 3/8 in. Assuming that the water decreased at a constant rate, how much did the water level drop each hour?
Answer:
[tex]\frac{1}{26}[/tex] inches
Step-by-step explanation:
In order to solve this problem, we need to create a ratio.
Since we're looking for the rate per hour, we need to find how long it is from 10pm to 7:45am.
10pm + 2 hours = 12 AM
12 AM + 7.75 hours = 7:45 AM
So in total, it's 9.75 hours.
[tex]\frac{3}{8}[/tex] is the same as 0.375.
Our fraction will become [tex]\frac{0.375}{9.75}[/tex], which can simplify down to [tex]\frac{1}{26}[/tex].
Now we can create the proportion:
[tex]\frac{1}{26}=\frac{x}{1}[/tex]
Now we solve for x by cross multiplying.
[tex]1\cdot1=1\\\\1\div26=\frac{1}{26}[/tex]

Using the digits 0-9, at most one time each, create five ordered pair that represent a linear
function that has a greater rate of change than the following (explain how u got that answer)
Answer:
(-9, 0), (-8, 1), (-7, 2), (-6, 3) and (-5, 4)
Step-by-step explanation:
From the graph attached,
Ordered pairs which lie on the given line (-9, 0), (0, 3), (3, 4), (6, 5) and (9, 6).
Since all the points lie on the same line, rate of change of the linear function will be defined by the slope of the given line.
Slope of the line passing through (0, 3) and (3, 4) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{4-3}{3-0}[/tex]
[tex]m_1[/tex] = [tex]\frac{1}{3}[/tex]
Now we have to find the ordered pairs which represent a linear function having slope greater than [tex]\frac{1}{3}[/tex].
So the points will be (-9, 0), (-8, 1), (-7, 2), (-6, 3) and (-5, 4).
Slope of the linear function passing through (-9, 0) and (-8, 1)
[tex]m_2[/tex] = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{1-0}{-8+9}[/tex]
= 1
Here [tex]m_2>m_1[/tex]

Answer:
The minimum value = 4
The maximum value = 9
The first quartile, Q₁ = 6
The second quartile, (median) Q₂ = 7
The third quartile, Q₃ = 8
The box plot showing the above data is attached
Step-by-step explanation:
The given data set is 4, 5, 5, 5, 6, 6, 6, 6, 7, 7, 7, 7, 7.5, 7.5, 8, 8, 8.5, 8.5, 9
From the data, we have;
The minimum value = 4
The maximum value = 9
The first quartile, Q₁ = (n + 1)/4th term = (19 + 1)/4 = the 5th term = 6
The second quartile, (median) Q₂ = (n + 1)/2 term = (19 + 1)/2 = the 10th term = 7
The third quartile, Q₃ = 3×(n + 1)/4th term = 3×(19 + 1)/4 = the 15th term = 8

Df = 9x -39 find EF.
DE =47
Greetings from Brasil....
Looking at the figure we can say that:
DF = DE + EFDF = 9X - 39
DE = 47
EF = 3X + 10
inserting these data in the 1st expression....
DF = DE + EF
9X - 39 = 47 + (3X + 10)
9X - 39 = 47 + 3X + 10
9X - 3X = 57 + 39
6X = 96
X = 96/6
X = 16
EF = 3X + 10 anb X = 16, so
EF = 3·16 + 10
EF = 48 + 10

is √13 greater or less than 3.5
Answer:yes it is greater
Step-by-step explanation:
Step-by-step explanation:
Hey, there!!
[tex] \sqrt{13 \: } \: is \: not \: greator \: than \: 3.5[/tex]
Because, root 13 means 3.60 also,
So, when you see 3.5 and 3.6 then it's obvious that 3.6 is greator.
Or if you see it in fractional form.
it will be,
18/5 and 7/2.
when we take a like term,
18×2/10 and 7×5/10
They will be ,
36/10 and 35/10.
Which implies 36/10>35/10.
So, the answer is root 13 is not greator than 3.5.
Hope it helps....

Find X. Need help ASAP
Answer:
A
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
the product of the external part and the whole of the secant is equal to the square of the tangent, that is
48(48 + x) = 60² = 3600 ( divide both sides by 48 )
48 + x = 75 ( subtract 48 from both sides )
x = 27 → A
