I believe it is 1250
Explanation: Area of a triangle=1/2bh-1/2•20•30
Area of square=bh-25•25
Add your answers together then you get 1250
Answer:
Yes! I use this site all the time and my questions always get answered quickly!
Step-by-step explanation:
I'm going to assume the crust covered by the dosenot matter because the total surface area cannot be found without the depth of the pie.
So the surface are is the area of the top of the pie, the top of the pie is circular and is equal to 2

r²
The diameter is the sum of 2 radii, hence r=8
D=12
= 2r =12
r=8
With the raduis the area can be found
A= 2

r²
A=2

8²
A=2(64)

A=128

If the pie cost 10.99, the cost per inch can be found by dividing the area by cost
cost/inch =128

/10.99
cost/inch =11.64

= 11.64(3.14)
= 36.57
The pie costs 36 cents per square inch
Answer:
Step-by-step explanation:
<u>Sides of the picture added margin:</u>
<u>Solution</u>:
- A(margin) = Total area - A(picture)
- (8 + 2x)(5 + 2x) - 5*8 = 30
- 4x² + 10x + 16x + 40 - 40 - 30 = 0
- 4x² + 26x - 30 = 0
- 2x² + 13x - 15 = 0
- x = (-13 + √(13² + 2*4*15))/4
- x = (-13 + 17)/4
- x = 1 cm
Note. The other root is ignored as negative.
So, just divide:
52.50 / 6 = 8.75
This means that she earns $8.75 an hour.
If this is her hourly salary, then multiply 8.75 x 11
8.75 x 11 = 96.25
So, if Paula works for 11 hours, she will earn $96.25!
