Hey there!
Here are the steps involved in answering this question:
1. We know that 36 handbags were sold for $1620 during the sale.
2. We want to know how much money they earned by selling 36 handbags for 49 dollars each.
Steps:
1. Since 36 handbags were also sold before the sale, multiply 49 by 36.
36 x 49 = 1764
They earned $1764 before the sale.
Now, find the difference between each of the sales.
1764 - 1620 = 144
Answer: $144

Known :
r = 10 m
h = 11 m
Asked :
V = ...?
Answer :
V = πr²h
= 3.14 × 10² × 11
= 3.14 × 100 × 11
= 314 × 11
= <u>3</u><u>4</u><u>5</u><u>4</u><u> </u><u>m³</u>
So, the volume is 3454 m³

Problem 11
<h3>Answer: h =
2A/b</h3>
------------------
Explanation:
We need to get h by itself. To do so, we first multiply both sides by 2. Then we divide both sides by b
A = (1/2)*b*h
2A = b*h
b*h = 2A
h = 2A/b

Problem 12
<h3>Answers:</h3>
- Equation: (n+2)/5 = 14
- Solution to that equation: n = 68
------------------
Explanation:
The number n is increased by 2 to get n+2
Then we divide by 5 to get (n+2)/5
This is set equal to 14 to get the equation (n+2)/5 = 14
Solving the equation would look like this
(n+2)/5 = 14
n+2 = 5*14 .... multiply both sides by 5
n+2 = 70
n = 70-2 .... subtract 2 from both sides
n = 68
================================================
Problem 13
<h3>Answer: Not a solution</h3>
------------------
Explanation:
We'll replace every copy of x with -3 and simplify
-2x + 5 > 13
-2*(-3) + 5 > 13
6 + 5 > 13
11 > 13
The last inequality is false because 11 is not greater than 13. Since the last inequality is false, this makes the first inequality false when x = -3.
Therefore, x = -3 is not a solution.
