The histogram shows the number of items sold at The Clothes Horse one week. About what percent of items sold cost less than $40

A. 55%
B. 56%
C. 34%
D. 25%

Answers

I’m pretty sure the correct answer to this is D
The answer is C
because if you were to add up all the frequencies together of each price range it would be 320 and the total frequency that cost less than $40 is 110, so if you divide 110 and 320 you’d get a decimal of 0.34 which is 34%

A rectangle has a length that is 9 inches less than twice its width. The area of the rectangle is 180 square inches.
a. Write an equation that represents the situation.
b. Find the length and width of the rectangle.
c. Find the perimeter of the rectangle.
pls help lols

Answers

Answer:

Step-by-step explanation:

a) Let the width = w

Two times its width = 2*w = 2w

9 inches less than 2w = 2w - 9

Length = 2w - 9

Area of rectangle = length *width = 180 square inches

(2w - 9 ) * w = 180

2w*w - 9*w = 180

2w² - 9w - 180 = 0

b) sum = -9

Product= -360

Factors  = -24 , 15    {15 *[-24] = -360 and 15 + (-24) = -9 }

2w² - 9w - 180 = 0

2w² - 24w + 15w - 180 = 0

2w(w - 12w) + 15(w - 12) = 0

(w -12) (2w + 15) = 0

{Ignore 2w + 15 = 0 as measurements cannot be a -ve value}

w - 12 = 0

w = 12 inches

l = 2w -9

 = 2*12 - 9

= 24 - 9

l = 15

length = 15 inches

Width = 12 inches

c) Perimeter = 2 *(length + width)

                     = 2*(15 + 12)

                     = 2 * 27

                     = 54  inches

Tell whether the angles are complementary or supplementary. Then find the value of x.

this just confused me a bit. x - 20? They are complimentary so ik the other side has to be 20

Answers

As you should already know that the angle shown is 90°.

So,

x + (x - 20) = 90

Now we have to solve for x. To find x we need to isolate it (get it by itself)

Add 20 on both sides:

x + x = 110

Simplify:

2x = 110

Now divide 2 on both sides (to get x by itself)

x = 55


Let’s check our answer:

55 + ( 55 - 20) = 90

55 + 35 = 90

90 = 90

So your answer should be x = 55.

Taylor emptied out her change jar to buy a new soccer ball for practice. The jar contained 128 coins consisting of quarters and dimes that totaled $25.10. Which system of equations could be used to determine how many quarters, q, and how many dimes, d, Taylor had in her change jar?

Answers

Answer:

.25q+.10d=25.10

q+d=128

Step-by-step explanation:

Since a quarter is 25 cents and a dime is 10 cents that is how you figure out your first equation. You set it equal to 25.10 because that is the amount of money it totals to. The second equation (q+d=128) is used because the amount of quarters plus dimes needs to make 128.

Let q be the no. of quarters and d be the no. of dimes.

q+d=128
25q+10d=2510

These are the system of equations. To solve it, we do this:

q=128-d
25(128-d)+10d=2510
3200-25d+10d=2510
15d=690
d=46
q=128-46=82

If 47% of a schools population are girls what percentage are boys?

Answers

53% is the answer

Step-by-step explanation:

100%-47= 53%

Answer:

53% of the school is boys

Step-by-step explanation:

I can't really explain this in full detail since its pretty simple but all we would have to do is take 100 (the full precentage) and subtract 47 from it because we know that this is the precentage of girls in the school, and our answer would be 53%.

6x + 12 = 10x − 4 1. Solve for x using two different methods

Answers

Answer:

x=53/4 or 4x=53

Step-by-step explanation:

First move the variable to the left-hand side and change its sign.

6x+12-10x=-41 to 6x-10x=-41-12

Then collect the like terms

6x-10x=-41-12 to -4x=-41-12 which equals to -4x=-53

Now you divide both sides of the equation by -4

-4x=-53 to x=53 over 4 then if you want you divide which gives you x=13.25

Second way:

Kind of the same thing as the first one

Move the variable to the left-hand side and change its sign

6x+12=10x-41 to 6x=12-10x=-41

Then you collect the like terms

6x-10x=-41-12 to -4x=-41-12

Now you multiply both sides of the equation by -1

-4x=-53 to 4x=53

The Lunchroom Murder
On an otherwise uneventful Thursday afternoon police heard a shot inside the local bistro, Ernie’s Lunchroom. They rushed in and found the scene shown in Figure 1.4.
They identified the body as that of a prominent racketeer named Fannin. Ernie, who is both the owner and only employee, had only one fact to tell: the murderer had leaned against the wall while firing at point-blank range. The imprint of his hand is in clear view.

The police have also noticed that the cash register had just been rung up at $8.75.
This is a difficult case. Your investigative team must attempt to determine which of the people in the lunchroom killed Fannin. You will have to observe the details carefully. There is enough evidence to help you explain most of what happened.

John wanted to save money to buy a new outfit. John saved $28.80 in April, $21.90 in May and $21.00 June. However, he also had to spend $28.60 on school supplies and $43.50 on his dog. if the outfit costs $182.60, how much money does John still need to save?

Answers

To solve this question you would need to calculate the amount of money he saved:
28.80+21.90+21=$71.70
Now you would need to subtract everything he spent his money on:
71.70-28.60-43.50=$4.60
Now you would need to do
182.60-4.60=$178

So John would have to save $178 to buy his new outfit. :-)
$175.40 ( 2 decimal place if its in dollars )

working:

Total save before spending: $79.3
After spending $79.3 - $ 28.60 - $43.50= $7.2
How much josh need to save: $182.60-$7.2 = $175.4

Answer - Part A:

I would say "whole".

Step-by-step explanation:

So, it talks about the discount being 30% or $24 dollars. This is only part of the original price.

Where, the original price is the total price. So, the means that it is the whole price.

Just to help:

Answer - Part B: The original cost of the jeans are $80.

Step-by-step explanation:

If you find 30% of 80, then you will have to do x/80 = 30/100. Next, you will cross multiply (x times 100 and 80 times 30), which gives you 100x and 2,400. Now, you will divide both numbers by 100. You should now have x and 24. So, x = 24.

So, see? 30% of 80 is $24.
