Answer:
80 + 4 + 2/10 or 0.2 + 2/100 or 0.02. When I wrote the fractions, it really depends on what your teacher taught you to do.
Step-by-step explanation:
8 x 10 + 4 x 1 + 2 x 1/10 + 2 x 1/00
That is just the explanation for the equation.
7 out of 50 is the same as 7/50
First, change the fraction into a decimal by dividing.
7 / 50 = 0.14
Second, change the decimal into a percentage by multiplying by 100%.
0.14 * 100% = 14%
18 out of 20 is the same as 18/20
First, change the fraction into a decimal by dividing.
18 / 20 = 0.9
Second, change the decimal into a percentage by multiplying by 100%.
0.9 * 100% = 90%
Best of Luck!

Answer:
y = 5 - 2x
Step-by-step explanation:
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
