Answer each question. Show your reasoning. a. 125% of e is 30. What is e? b. 35% of f is 14. What is f?

a. e= 24

b. f = 40

Step-by-step explanation:

a. 125% of e = 30

125/100 × e = 30

1.25 × e = 30

1.25e = 30

e = 30/1.25

e = 24

b. 35% of f = 14

35/100 × f = 14

0.35 × f = 14

0.35f = 14

f = 14/0.35

f = 40

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
