Sandy works at a clothing store. She makes $8 per hour plus earns 10% commission on her sales. She worked 70 hours over the last two weeks and had a total of $1,612 in sales before taxes.
Which of the following is closest to how much she will earn in hourly wages and commission for those two weeks?
A.
$721
B.
$560
C.
$161
D.
$217
Answers
Answer:
A
Step-by-step explanation:
First, I'm going to work out the hourly wages for the 2 weeks.
$8 x 70hours = $560
(8 x 7 = 56 x 10 = 560)
Next, work out the commision.
10% of $1612
1612 ÷ 10 = 161.2
Finally, add together both the hourly wages and commision.
161.2 + 560 = 721.2
Round it down to a whole number.
721 , Add on the dollar sign.
It's answer A, $721.
I’m pretty sure it’s 721$

Simplify the expression 6h+(−7.9d)−16+5d−3.3h.
Answers
Answer:
2.7h-2.9d-16
Step-by-step explanation:
The first thing you need to do is combine like terms.
So, given 6h+(-7.9d)-16+5d-3.3h
-7.9d can combine with 5d, and 6h can combine with -3.3h.
-7.9d+5d=-2.9d
6h-3.3h=2.7h
Now all you have left is the -16 which has nothing to be combined with. Therefore, giving you the answer 2.7h-2.9d-16.

Francisco wants to find the product of 382 trays of apples and the 18 apples that fit in each tray. He decides to find the answer by breaking 18 into equal parts: 9 and 9. He says that if he multiplies 382 by 9 and then multiplies the product by 9 again, he can find the answer.
Will Francisco’s strategy work? Why or why not?
Answers
Answer:
Please mark me the brainliest
Step-by-step explanation:
Yes, Francisco's strategy will work.
Breaking 18 into 9 and 9 means that he is using the distributive property of multiplication, which states that a(b+c) = ab + ac. In this case, he is breaking 18 into 9 and 9, so he can rewrite the product of 382 trays and 18 apples as:
382 trays x (9 apples + 9 apples)
Using the distributive property, this can be expanded as:
(382 trays x 9 apples) + (382 trays x 9 apples)
This simplifies to:
3,438 trays x 9 apples
Which gives the correct answer of 30,942 apples. Therefore, Francisco's strategy works because he correctly applied the distributive property of multiplication to break down the problem into simpler parts.

Amani computed in a two-way table the relative frequencies of sales of homes listed with two different real estate companies.
Which statement best describes the relationship between the two variables?
A) There is an association because the relative frequencies by column are similar.
B) There is an association because the relative frequencies by row are similar.
C) There is no association because the relative frequencies by column are similar.
D) There is no association because the relative frequencies by row are similar.
Answers
The answer the third option.
When you look at the data, in the first column, the frequency of sales of both are similar. Even the second column shows similar data. Association is determined if there is a significant difference between the data in each column/row depending on what you are aiming to answer.
In this case, we look at it per column because you want to compare the frequencies of sales of each company which are aligned by columns. So we know to look at the columns and not the rows.

A triangle has an area of 15. One of its sides has length 10. What is the length of the altitude to that side?
Answers
Answer:
Altitude = 3
Step-by-step explanation:
Given the area of a triangle as 15, with a length of 10:
We can use the following formula for finding the area of a triangle:
Area (A) = ½bh
Where:
Base (b) = 10
Height (h) or altitude = unknown
Substitute the given values into the formula:
Area (A) = ½bh
15 = ½(10)h
15 = 5h
Divide both sides by 5 to solve for h:
\(\displaystyle\mathsf{\frac{15}{5}\:=\:\frac{5h}{5} }\)
h = 3
Therefore, the length of the altitude or height of the given triangle is 3.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

Assuming we are trying to find area
C: 270
d: 229.32
e: 63
f: 600
Step-by-step explanation:
c) base times height divided by 2 will give the area of a triangle. Here, height is 15m and the base length is 36 m.
area=(15*36)/2= 270
d) height is 16.8m, and the base length is 27.3, so
area= (16.8*27.3)/2= 229.32
e) Height is 9yd, base is 14 yd
(9*14)/2=63 yd
f) Not as hard as it may seem. We are going to do the same exact thing we did in c. All you have to do is reorient the triangle so that the right angle is at the bottom of the triangle.
With this new orientation, we see that the height is 40 ft and the base is 30 ft.
(40ft*30ft)/2= 600ft

d: 229.32
