#8) Subtract 350 from each side then divide each side by 25 to get (c-350)/25 = h.
Plug in 950 for c to get (950-350)/25 = h.
600/25 = h = 24 hours.
#9 is the same as number 8 just with one more variable. Subtract 2.25h from both sides and divide both sides by 1.75. Then plug in 18.25 for t and 5 for h. Then solve for d.
Answer:
264ft^2
Step-by-step explanation:
First find the area of the body of the house which is the rectangle.
18*12=216
Then find the are of the triangle or roof given by 1/2(b)(h)
1/2(12)(10)=60
Then Find the area of the window which is 3*4=12 and subtract 12 from 60 to find the area of the roof with the window.=48
Add 48 the roof and 216 the rectangle to get total painted area. =264 ft^2
Answer:
x≈5
Step-by-step explanation:
x^2-5x6=0
x^2-30=0
x^2-30+30=30+0
x^2=30
x≈5
Answer:
80°
Step-by-step explanation:
diameters intersect at centre so measure of arc is the angle at the centre.
so x=80°
The ratio is 75% (3/4) so the answer to the question is 27 chocolate chip cookies
