Answer:
y = 15 hour - 3 hours/day x days
y = 15 - 3x
y-intercept = 15 - 3(0)= 15 which is the amount of volunteer hours she must complete at day 0.
0 = 15 - 3x
3x = 15
x = 5 (Number of days she would have to volunteer)
Equation: y = 15- 3x
Step-by-step explanation:
Subtract the 2 on both sides to get -4x=-5x+7, then add -5 on both sides and get 1x=7 then divide 1 on both side to get x=7
You can get the number by dividing 19.2 by 0.40
The number is 19.2/0.40 = 48
Answer:
85 cm²
Step-by-step explanation:
The base is a square with side length 5 cm. The area of this base is
A = s² = (5 cm)² = 25 cm².
If the slant height of each lateral face of the pyramid is 6 cm, then we can find the area of each such face using the area-of-a-triangle formula,
A = (1/2)(base)(height), which here is
A = (1/2)(5 cm)(6 cm) = 15 cm² per lateral side.
The total area of these sides is 4(15 cm²) = 60 cm².
Then the total surface area of the pyramid is A = 60 cm² + 25 cm² = 85 cm².
