Hello!
To solve questions 19 and 21, firstly, we need to convert the percentages to decimals. There are two ways to convert them.
- The first way is to divide the percentage by 100 because <u>all</u> percentages are out of 100.
- The second way is to move the decimal place two times to the left, in which case, it is the same thing as dividing by 100.
After finding the converted percentage, you multiply the cost by that decimal. That will be your final answer according to the problem, but that is not true in some cases (like number 19).
19). Sales Tax
We are given a Digital Assistant priced at 399 dollars. We are finding the total price including the sales tax, so we need to add the total price and the sales tax together.
7.75 / 100 = 0.0775
399 × 0.0775 = 30.9225 | This can be rounded to about 30.92 dollars.
399 + 30.92 = 429.92 dollars
The total price including the sales tax is 429.92 dollars.
21). Women in the Navy
Given that there is a 335-person crew, and of which, 13% are female, we need to find how much females are on the navy guided-missile destroyer.
13 / 100 = 0.13
335 × 0.13 = 43.55
Since we are working with humans, we need to round it to a whole number.
Therefore, there are about 44 crew members that are women.
<u>Final answers</u>:
- 429.92 dollars
- 44 women
Answer:
32
Step-by-step explanation:
b^2c^1
Let b=-4 and c= 2
(-4)^2 ( 2)^1
16 * 2

There are 24 oranges and 36 apples.
Each basket has to have the same number of fruit
So lets say that each basket will have exactly one orange and apple.
To get the maximum number of baskets, we have to use either all of the apples or all of the oranges.
You can't have 36 baskets, because you only have 24 oranges, even though there are enough apples.
But you can 24 baskets, because there are enough apples and oranges.
So you can use all of the oranges to make 24 baskets (and you'll be left with 12 apples)
Answer: F. 24.
We have that in this case the following equalities are met:
DH = HF
x + 3 = 3y
GH = HE
3x - 3 = 5y + 4
We then have the following system of equations:
x-3y = -3
3x-5y = 7
Resolving the system graphically we obtain the following values:
x = 9
y = 4
Note: see attached image.
Answer:
The values of x and y are:
x = 9, y = 4
