Hope this helps
Answer:
Step-by-step explanation:
The general equation for a direct variation is y = k*x
So your first step (usually) is to find k
y = k x
when x = 4
then y = 50
- y = k*x
- 50 = k * 4 Divide by 4
- 50 / 4 = k*4/4
- 12.5 = k
Now you can find the value of y when x = 2
- y = k*x
- k = 12.5
- x = 2
- y = ?
y = 12.5 * 2
y = 25
The second one it's double.
for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³
