How would you use estimation to evaluate this expression: 10.2 × [(2×3.7)+8]

1 answer:

4 0

Well, first you would estimate all the terms: 10.2 to 10, 2 to 2(keep the same), 3.7 to 4, and eight to eight.

So you have 10 x [(2 x 4) + 8]
then you would evaluate this expression using order of operations

10 x [(2 x 4) + 8]
10 x [8 + 8]
10 x 16
160

Mixed numbers have both fractions and _____ numbers.

Vladimir [108]

Answer:

"Whole"

Step-by-step explanation:

A mixed number is made out of two parts: the fraction and the whole number.

Other material would say that a mixed number has three parts: the numerator, denominator, and the whole number. This is also correct, as the numerator and denominator make up the fraction in the mixed number.

The fraction is the 'incomplete' part of the mixed number, and the whole number is the 'complete' part of the mixed number.

For example:

$3.25 = 3\frac{1}{4}$

0.25 = 1/4

3.00 = 3

"Whole" should fill in the blank and make the statement true.

Inga [223]

Answer:

1. New balance on July 1=1,484.962

2. New finance charge=97.1362

Step-by-step explanation:

The initial unpaid balance=1753.05 by June

Amy paid 365.39 on June

The unpaid balance after paying 365.39=Initial unpaid balance-amount paid on June

where;

Initial unpaid balance=1753.05

Amount paid on June=365.39

replacing;

The unpaid balance after paying 365.39=(1753.05-365.39)

The unpaid balance after paying 365.39 =1,387.66

The interest will be charged on the unpaid balance of 1,387.66

Interest=Principal×rate×time

Principal=1,387.66

Rate=7% per month

Time(in months)=Early June to early July=1 month

replacing;

Interest=1,387.66×(7/100)×1=97.1362

New balance on July 1=Unpaid balance after paying+Interest

where;

Unpaid balance after paying=1,387.66

Interest=97.1362

replacing;

New balance on July 1=(1,387.66+97.1362)=1,484.962

New balance on July 1=1,484.962

New finance charge=97.1362
