How would you get the answer of how much change he received

Step-by-step explanation:

Givens

I foot of sill = 1.75

35 feet of sill = x

Paid with 100 dollars.

Solution

First part

Solve the proportion

1/35 = 1.75/ x                 Cross multiply

1*x = 35 * 1.75

x = 61.25

Second part

Get the change.

Change = 100 - 61.25

Change  = 38.75

The change =

3 tens                30.00

1 five                   5.00

3 ones                3.00

3 quarters           .75

Total                 38.75

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
