A1) Using estimate, the solutions to the following are:
A) is -14.
B) is 31.
C) is 38.
D) is -74.
1. The remaining amount in Brock's account after writing the checks is <u>$2,290</u>.
2. Linda put <u>$831</u> in her savings account after meeting her expenses.
<h3>What is an estimate?</h3>
An estimate is a rough calculation.
To do an estimate, the figures may be appropriated or rounded up.
<h3>Estimates:</h3>
A. –42.3 ÷ 3.4
= -14 (–42 ÷ 3)
B. 16.1 – (–14.7)
= 31 (16 – (–15)
C. –15.52 + 54.25
= 38 (–16 + 54)
D. ‐67.8 ‐ 5.72
= -74 (‐68 ‐ 6)
<h3>Brock:</h3>
The amount in Brock's checking account = $3,084
<u>Checks</u>:
Rent $350
Auto repair $275
Loan payment of $169
Total amount for checks = $794
Remaining amount = $2,290 ($3,084 - $794)
<h3>Linda:</h3>
The total amount of the paycheck = $2,312
<u>Expenses</u>:
Rent $157
Food $322
Child care $478
Transportation $234
Miscellaneous expenses $290
Total expenses = $1,481
Savings account = $831 ($2,312 - $1,481)

10 bows in total so every bow will be 10%
Since there is 4 purple bows the probability Nerissa will chose a purple bow is 40/100

Answer:
9 m²
Step-by-step explanation:
s = half the perimeter = (a+b+c)/2
the perimeter in our case is
a+b+c = 16
so, s = 16/2 = 8
and the sides are
7 m
6 m
16 - 7 - 6 = 3 m
therefore, we get
area = sqrt(8(8-7)(8-6)(8-3)) = sqrt(8×1×2×5) = sqrt(80) =
= 8.94427191... ≈ 9 m²
