Answer:
- 0.32
Step-by-step explanation:
because if you add 0.08 and 0.25 you get 0.32 but then you are subtracting that from the original price so I think it would be - 0.32

Find the measure of angle x in the figure.
Note: Angles not drawn to scale.
Angle x measures=
Answer:
x = 125°
Step-by-step explanation:
There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.
Total of angles
= (n - 2)•180°
Put in 7, because there are 7 angles.
= (7 - 2)•180°
= 5•180°
= 900°
So the total of the angles should be 900°. We know all of the angles except one.
900° = 123°+129°+128°+128°+132°+135°+ x
900° = 775° + x
Subtract 775.
125° = x
The missing angle is 125°.

Ecologists measure the body length and wingspan of 127 butterfly specimens caught in a single field.
The wingspan of 127 butterfly specimens is an illustration of the line of best fit
The equation of the line of best fit is y = 3xThe slope means that as the wingspans increase and lengths of these butterflies increaseHow to determine the equation of the line?From the line of best fit of the graph (see attachment), we have the following points
(x,y) = (0,0) and (20,60)
Since the line passes through the origin, the equation of the line would be:
[tex]y = \frac{y_1}{x_1} * x[/tex]
So, we have:
[tex]y = \frac{60}{20} * x[/tex]
[tex]y = 3x[/tex]
Hence, the equation of the line of best fit is y = 3x
Interpret the slopeIn (a), we have the slope to be:
Slope = 3
The slope (3) is greater than 0.
This means that as the wingspans increase and lengths of these butterflies increase

Which of the following is the equation for the line perpendicular to the line 3x -2y =10 that passes through the point (7,5)?
A. Y = 2/3x + 29/3
B. Y = -2/3x + 1/3
C. Y = 2/3x + 1/3
D. Y = -2/3x + 29/3
The equation of the perpendicular line will be y = 29 / 3 - (2/3)x. Then the correct option is D.
What is the equation of a perpendicular line?Let the equation of the line be ax + by + c = 0. Then the equation of the perpendicular line that is perpendicular to the line ax + by + c = 0 is given as bx - ay + d = 0. If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.
The equation of the line is given below.
3x - 2y = 10
The equation of the line that is perpendicular line is given as,
2x + 3y + d = 0
The equation is passing through (7, 5). Then we have
2(7) + 3(5) + d = 0
14 + 15 + d = 0
29 + d = 0
d = - 29
Then the equation of the line is given as,
2x + 3y - 29 = 0
2x + 3y = 29
3y = 29 - 2x
y = 29 / 3 - (2/3)x
The equation of the perpendicular line will be y = 29 / 3 - (2/3)x. Then the correct option is D.

100 points!!!!! How many more brick houses did Company N build than Company M?
Answer:
company N built 10 more brick houses
Step-by-step explanation:
if company M builds 2x as many wooden houses as the do brick houses that would be 1/2 of 100 which is 50, and the ratio of wood houses to brick houses for company M is 5:3, 5x20=100 3x20=60. 60-50=10
Answer:
10 houses
Step-by-step explanation:
If Company M builds half as many brick houses as wood houses, then if this company builds 100 wood houses, it builds 50 brick houses.
For Company N, create a linear equation showing the relationship between wood houses (x) and brick houses (y). For every increase in x by 5, y increases by 3:
y = (3/5)x
Therefore, when x = 100: y = (3/5)(100) = 60
So Company N builds 60 brick houses when it builds 100 wood houses.
Company N - Company M = 60 - 50 = 10 houses
Therefore, Company N built 10 more brick houses than Company M.

Answer:
Step-by-step explanation:
a
Opposite means add a negative sign in front of it.
The opposite of 6 is -6,
7 --> -7,
-10 --> 10.
Reciprocal means flip it.
Reciprocal of 6 is 1/6
of 7 is 1/7
of -10 is -1/10
Opposite reciprocal means add a negative sign AND flip it.
6 --> -1/6
7 ---> -1/7
-10 --> 1/10

1. Write an equation to find the number of toppings, x, when you would pay for the same amount for Pizza A and B.
So, we have to make a relationship between Pizza A and Pizza B, and this is talking about the pizza and toppings so,
$10 + $1.50x = $12.50 + $1.00x
Now we solve for the x values and the starting amount of money,
0.50x = 2.50
and that gives us,
$5
The answer also solves for the bottom one, the answer you need on the top one is,
$10 + $1.50x = $12.50 + $1.00x
The volume of this triangular prism is 32 cubic inches. What is the value of d?
Answer:
Divide the volume by the length of the prism to get the area of the face:
468/13 = 36 square yards.
The area of the face ( triangle) is 1/2 x base x height
Replace with what you have:
36 = 1/2 x 9 x g
Multiply both sides by 2 to remove the 1/2:
72 = 9 x g
Divide both sides by 9 to find g:
g = 72 /9
g = 8 yards.
