Answer:
[tex]4\frac{3}{8}[/tex] yards of wood
Step-by-step explanation:
The correct question is Hakim is making birdhouses. Each birdhouse uses 7 /8 yard of wood. What is the total length of wood Hakim will need to build 5 birdhouses?
Answer: Given that the amount of wood need to produce one bird house is 7/8 yard, for 5 birdhouse, the amount of wood needed would be 5 times the number needed for one birdhouse. It is given by:
Amount of wood needed for 5 birdhouse = 5 × amount of wood for 1 birdhouse
Amount of wood needed for 5 birdhouse = 5 × 7/8 yards = 35/8 = [tex]4\frac{3}{8}[/tex] yards of wood
P(A) = 0.33, P(A and B) = 0.25, find P(B

Answer/Step-by-step explanation:
In mathematics, there's an order to follow in solving calculations like the problems given above. The acronym, PEDMAS illustrates or makes us remember which order to follow. The acronym stands for:
P - Parenthesis. Given any problem to solve, first, solve any operation within a parenthesis. That is, expressions that are grouped together.
E - Exponents. Next in line of priority order is to solve expressions involving exponents.
D - Division
M - Multiplication
A - Addition, and
S - Subtraction.
Now, solve each expression given in the correct order of operation using PEDMAS:
10 - 3³ ÷ 9
10 - 27 ÷ 9
10 - 3
= 7 (the order of operation is EDS = Exponent, Division, and lastly, Subtraction)
7² ÷ (4 + 3)
7² ÷ 7
49 ÷ 7
= 7 (order of operation = PED)
7 × 5 - 2²
7 × 5 - 4
35 - 4
= 31 (EMS)
(6 + 2²) × 10
(6 + 4) × 10
10 × 10
= 100 (PM)
3 × 6 + 8²
3 × 6 + 64
18 + 64
= 82 (EMA)
4³ - 10 ÷ 5
64 - 10 ÷ 5
64 - 2
= 32 (EDS)
3² × 2 - 9
9 × 2 - 9
18 - 9
= 9 (EMS)
9 × 3² - 8
9 × 9 - 8
81 - 8
= 73 (EMS)
6² ÷ 3 - 5
36 ÷ 3 - 5
12 - 5
= 7 (EDS)
(9 - 5)² ÷ 4

Which angle pairs are supplementary? Check all that
apply.
<1 and <2
<4 and <3
<4 and <5
<7 and <5
<3 and <6
Answer:
∠4 and ∠3
∠4 and ∠5
∠3 and ∠6
Step-by-step explanation:
A pair of angles is said to be supplementary when the 2 angles add up to give 180°.
Two right angles add up to give 180°. Also, if we have two angles on a straight line, their sum = 180°, according to the linear pair property.
Thus, since m< 3 is given as 90°, m<4 = 90°.
m<4 + m<3 = 180°.
Therefore, <4 and <3 are supplementary.
<4 and <5, <3 and <6 are both linear pairs, therefore they are also supplementary.

Three students need to produce a prime factorization of 48. Donna states that the first factors in the tree should be 6 and 8. Larry states that the first factors in the tree should be 4 and 12. Trish states that the initial factors of 48 do not affect the prime factorization. Explain why Trish is correct. Why is trish correct?
Answer:
Below.
Step-by-step explanation:
The initial factors do not affect the prime factorisation.
Continuing the factorisation will lead to the same result whichever initial factors you choose.
48
4 * 12
2*2 * 2*2*3
= 2*2*2*2*3
48
6 * 8
2*3 * 2*2*2
= 2*2*2*2*3.
Answer:
A prime factorization is the product of the prime numbers that multiply to give the original number. 48 will have a prime factorization of 2(2)(2)(2)(3), or 24(3), regardless of the initial factors.

Solve the following absolute value equation. If needed, write your answer as a fraction reduced to lowest terms. Please explain your answer |y−43|−|y−35| =0
Answer:
y = 39
Step-by-step explanation:
|y−43|−|y−35| =0
add |y−35| to each side
|y−43|= |y−35|
This tells us that y must be between 35 and 43
That means |y−35| is positive so we can remove the absolute value signs
|y−43| is negative so we negate each term ( or multiply by -1)
-y+43 = y - 35
Add y to each side
y-y+43 = y+y-35
43 = 2y -35
Add 35 to each side
43+35 = 2y
78 = 2y
Divide by 2
78/2 = 2y/2
39 = y

What the measure of AOB?
Answer:
∠ AOB = 17.5°
Step-by-step explanation:
∠ AOB + 110 + ∠ COD = 180 ( sum of angles in straight line )
[tex]\frac{1}{3}[/tex] ∠ COD + 110 + ∠ COD = 180 ( subtract 110 from both sides )
[tex]\frac{4}{3}[/tex] ∠ COD = 70 ( multiply both sides by 3 to clear the fraction )
4 ∠ COD = 210 ( divide both sides by 4 )
∠ COD = 52.5°
Thus
∠ AOB = [tex]\frac{1}{3}[/tex] × 52.5° = 17.5°

The sum of two numbers is fifteen. One number is three less than the other. Determine the system of equations.
Answer:
let, one number be x
then, other number be x-3
X+X-3=15
or, 2X=15+3
or,2X=18
or,X=18÷2
or,X=9
one number =9
then another number=X-3=9-3=6
The system of equations with two numbers x ad y are,
⇒ [tex]x + y = 15[/tex]
⇒ [tex]x = y - 3[/tex]
Given that,
The sum of two numbers is fifteen.
And, One number is three less than the other.
Let us assume that,
Two variables for the numbers in the system of equations are x and y.
Hence, we can write the system of equations as,
The sum of two numbers is fifteen.
⇒ [tex]x + y = 15[/tex]
And, One number is three less than the other.
⇒ [tex]x = y - 3[/tex]
So, the system of equations is,
⇒ [tex]x + y = 15[/tex]
⇒ [tex]x = y - 3[/tex]

If you were to describe a rotation of triangle ABC what information would you need to include in your description
You would need to include the center of rotation. For many problems, the center is usually the origin (0,0). This is a default assumed center. Though the center could easily be any other point.
In addition, you also need the amount of rotation that is being applied (eg: 90 degrees).
The last bit of info you need is whether you're going clockwise or counterclockwise. For 180 degree rotations, it doesn't matter, but for everything else it does matter.
a saleswoman earns 60% commission on all that she sells. Last month she sold $400 worth of merchandise. How much commission (In dollars) did she earn last month?
Answer:
$240
Step-by-step explanation:
If she earns 60% commission, that means she only earns 60% of all sales. So if you take that 60% or (.60) you can multiply that 400 by .60, that equates to 240.

3 (2x + 2) = 18 + 4(x - 5)
Answer:
[tex]x=-4[/tex]
Step-by-step explanation:
So we have the equation:
[tex]3(2x+2)=18+4(x-5)[/tex]
Distribute the left and the right:
[tex]3(2x)+3(2)=18+4(x)+4(-5)[/tex]
Simplify:
[tex]6x+6=18+4x-20[/tex]
Combine on the right:
[tex]6x+6=4x-2[/tex]
Subtract 4x from both sides. The right cancels:
[tex](6x+6)-4x=(4x-2)-4x\\2x+6=-2[/tex]
Subtract 6 from both sides. The left cancels:
[tex](2x+6)-6=(-2)-6\\2x=-8[/tex]
Divide both sides by 2:
[tex](2x)/2=(-8)/2\\x=-4[/tex]
Thus, the value of x is -4.
Answer:
x = -4
Step-by-step explanation:
3(2x + 2)=18 + 4(x - 5)
6x + 6= 18 +4x - 20
6x - 4x = -2-6
2x = -8
x = -4

Solve for r. 7(r+1) = 20.3
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{r = 1.9}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{7(r + 1) = 20.3}[/tex]
Distribute 7 through the parentheses
⇒[tex] \sf{7r + 7 = 20.3}[/tex]
Move 7 to right hand side and change it's sign
⇒[tex] \sf{7r = 20.3 - 7}[/tex]
Subtract 7 from 20.3
⇒[tex] \sf{7r = 13.3}[/tex]
Divide both sides of the equation by 7
⇒[tex] \sf{ \frac{7r}{7} = \frac{13.3}{7} }[/tex]
Calculate
⇒[tex] \sf{r = 1.9}[/tex]
Hope I helped!
Best regards!!
r is 1.9
Solve 7(r+1) = 20.3
Remove the brackets by dividing both sides by 7:
7(r+1) / 7 = 20.3 / 7
r + 1 = 2.9
Take 1 to the other side so that you can be left with r. When you do this, the sign will change from positive to negative:
r = 2.9 - 1
r = 1.9
r is therefore 1.9

what is the percentage of the total variation in candy bar sales explained by the regression model? a. 78.39% b. 88.54% c. 100% d. 48.19%
Complete question :
A candy bar manufacturer is interested in trying to estimate how sales are influenced by the price of their product. To do this, the company randomly chooses 6 small cities and offers the candy bar at different prices. Using candy bar sales as the dependent variable, the company will conduct a simple linear regression on the data below:
City - - - - - Price ($) -- - Sales
River City - - 1.30 - - - - - - 100
Hudson - - - 1.60 - - - - - 90
Ellsworth - - - 1.80 - - - - - 90
Prescott - - - - 2.00 - - - - 40
Rock Elm - - 2.40 - - 38
Stillwater - - 2.90 - - 32
Answer:
78.39%
Step-by-step explanation:
what is the percentage of the total variation in candy bar sales explained by the regression model?
The question could be interpreted as meaning the percentage of the total variation in the dependent variable (candy bar sales) which can be explained by the regression model. Hence the independent variable is price. This variance can be known by calculating the Coefficient of determination (R^2) value of the regression model.
To save computation time, the R^2 value can be obtained using an online Coefficient of determination calculator.
To obtain the R^2 value, the values of the dependent and independent variables are entered. The R^2 value obtained is : 0.7839
Therefore the total proportion of variance in candy bar sales explained by the regression model is 0.7839 which is equivalent to:
(0.7839 * 100) = 78.39%

Answer:
-4-5
Step-by-step explanation:
The temp was at -4 and if it dropped that means you subtract another 5 from it which is -4-5
Answer:
The correct answer is -4 - 5.
Step-by-step explanation:
The original temperature is -4 degrees. Then, the temperature falls by 5 degrees. The temperature "falling" means that it is getting colder or that the temperature is getting lower. This lets us know that we need to use subtraction. The final answer is -4 - 5, which would give us the temperature of -9 degrees as the new temperature.
