Answer:

1. Option D.

2. Option A.

Step-by-step explanation:

1. Follow these steps to estimate the sum of 8.86 + 9.43 + 5.75:

Step 1: Sum the digits in the ones places of the whole numbers (these are: 8, 9 and 5).

Step 2: Round the decimal numbers to the nearest whole number:

0.86\approx 1\\\\0.43\approx0\\\\0.75\approx1

Step 3: Add them all together:

8+9+5+1+0+1=8+9+5+2=24

2. To estimate the difference of 83.92-47.23 employ the following procedure:

83.92-\\47.23\\........\\40.00\\\ -4.00\\\ \ + 0.70\\-0.01\\...........\\+36.00\\+0\ 0.69\\..............\\36.69

Rounded to the nearest whole number:

36.69\approx 37

PIT_PIT [12445]
<span>0.002 1/10 of what
=> (1/10)a = 0.002
=> Multiply both sides by 10 to solve for the unknown number, since we need the value whose one-tenth is 0.002.
=> 10 x (1/10)a = 10 x 0.002
=>  a = 0.02

Therefore, 0.002 is one-tenth of 0.02.
To verify, divide 0.02 by 10.
=> 0.02 / 10
=> 0.002
Hence, the solution is confirmed.

A quarter is approximately 0.07 inches thick. A dollar bill is approximately 4.3 × 10-3 inches thick.
lawyer [12517]

m = 6.57 and n = -2

Detailed explanation:

To solve this question, convert the thickness of a dollar bill into standard notation and compare the two thicknesses.

0.07 compared to 0.0043 results in 0.0657

0.0657 = 6.57 x 10^-2

Thus, a quarter is thicker than a dollar by 6.57 x 10^-2.

m = 6.57 and n = -2
