Michele is 52 inches tall. Her father is 6 feet 3 inches tall. Exactly how many taller is Michele's father than Michele?

Answers

The Michele's father is 23 inches taller than Michele.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Michele is 52 inches tall.

And, Her father is 6 feet 3 inches tall.

Now,

Since, We know that;

⇒ 1 feet = 12 inches

Hence, The age of his father = 6 feet 3 inches

                                             = 6×12 + 3

                                             = 75 inches.

Hence, The length for Michele's father taller than Michele is,

⇒ 75 - 52 inches

⇒ 23 inches.

from 40 bulbs tested by a quality controller, 3 are faulty calculate the expected number of faulty bulbs in a box of 500

Answers

Out of 40 bulbs, 3 were faulty.

3/40 were faulty

out of 500 bulbs, 'x' were faulty.

x/500 were faulty

(3)/(40) = (x)/(500)
cross multiply
40x=1500
Divide both sides by 40
x=37.5
Since you can't have .5 of a bulb, lets round up to 38
Answer=38 bulbs
