Need help with math word problems
Answer:
a. 80%
b.-20%
c.24%
d.-5%
e. $210
Step-by-step explanation:
Step-by-step explanation:
a) $153 - $85 = $68
68 ÷ 85 = 0.8 × 100 = 80
80% increased.
80% of $85 is $68
b) $340 - $272 = $68
68 ÷ 340 = 0.2 × 100 = 20
20% decreased
20% of $340 is $68
c)78,616 - 63,400 = 15,216
15,216 ÷ 63,400 = 0.24 × 100 = 24
24% increased
24% of 63,400 is 15,216
d)2580 - 2451 = 129
129 ÷ 2580 = 0.05 × 100 = 5
5% decreased
5% of 2580 is 129
e) 75% of $120
75 ÷ 100 = 0.75 × 120 = 90
120 + 90 = 210
she sell it for $210
I hope its help u☆
I need help on IXL also my profile says high school but I'm in 7th grade
Answer:
It should be 58 degrees. Good luck and have a nice day!
Step-by-step explanation:
If the angle on the opposite side is 32 degrees and the angle right next to it makes a 90 degree angle then the one on the opposite side is also 90 and 32. So just subtract 32 degrees from 90 and you get 58 degrees.
(sorry if that's confusing)
Answer:
58
Step-by-step explanation:
Use the right angle to find the missing angle. We know the one angle is 32.
90-32= 58
58 and your angle s are equal to each other because they are opposite angles.
Write a story that represents the math problem 2/6 times 3/4
There is only 3/4 of a pie left. Two families decide to split the pie. There are 6 kids total, and they decide that each kid should get a sixth of what's left of the pie. One family has 2 kids, so how much pie will they get?
So 2/6 of 3/4 is 1/4 or .25
Robert says he needs 250 plastic sleeves for his Pokemon card collection. He has 3,084 Pokemon cards. Each sleeve holds 12 cards. Do you agree with Robert? and why.
Answer:
Yeah
Step-by-step explanation:
3084/250 = around 6. I don't think you should shove 6 Pokemon cards in one sleeve thought I'd probably damage the card
Disagree
Robert actually needs 257 plastic sleeves, and here is why
Each plastic sleeve holds 12 card. 250 * 12 = 3,000
3,084 - 3000 = 84
84 ÷ 12 = 7
250 + 7 = 257
257 * 12 = 3,084

Can someone help me out
Answer:
the answer its c 122 is angle 1
Answer:
A. 32
Step-by-step explanation:
The two angles are equal to each other so you can set them equal and solve
2x+57=6x-71
Add 71 to both sides
2x+57+71=6x+0
2x+128=6x
Subtract 2x from both sides
128=6x-2x
128=4x
Divide 4 from both sides
128/4=x
32=x

A fashion photographer needs to hire a stylist to prepare his models. Chloe charges $165 for showing up, plus $71 per hour. Rodrigo charges $168 plus $68 per hour. The photographer realizes that, given the expected duration of his photo shoot, either stylist would cost him the same amount. What would the duration be? What would the cost be?
If the shoot lasted for BLANK
hours, either stylist would cost BLANK $
In the first hour it will cost $236 because for showing up and for the first hour.
but Rodrigo will be cheaper because the showing up money doesn't increase each hour, so in conclusion. Rodrigo is cheaper by $3

A recipe calls for 3 cups of sugar to 4 cups of flour.
What is the unit rate per cup of sugar?
0.75 cups of flour to 1 cup of sugar.
Step-by-step explanation: From the question, we are informed that a recipe calls for 3 cups of flour to 4 cups of sugar and told to calculate the unit rate.
It simply means what we need to calculate much flour to one cup of sugar. This will be:
= 3/4 = 0.75
Therefore, the unit rate will be:
0.75 cups of flour to 1 cup of sugar.

Answer:
[tex]\frac{x^2 - 9}{y^2 - 25} / \frac{2x^2 - 6x}{3y^2 - 15y} + \frac{3 - 1.5y}{y + 5} = \frac{3(3y + 2x)}{2x(y+5)}[/tex] If [tex]x \ne 0 \ \ or\ y \ne 0[/tex]
Step-by-step explanation:
Given
[tex]\frac{x^2 - 9}{y^2 - 25} / \frac{2x^2 - 6x}{3y^2 - 15y} + \frac{3 - 1.5y}{y + 5}[/tex]
Required
Solve
First, we change / to *
[tex]\frac{x^2 - 9}{y^2 - 25} * \frac{3y^2 - 15y}{2x^2 - 6x} + \frac{3 - 1.5y}{y + 5}[/tex]
Apply difference of two squares
[tex]\frac{(x- 3)(x+3)}{(y - 5)(y+5)} * \frac{3y^2 - 15y}{2x^2 - 6x} + \frac{3 - 1.5y}{y + 5}[/tex]
Factorize:
[tex]\frac{(x- 3)(x+3)}{(y - 5)(y+5)} * \frac{3y(y - 5)}{2x(x - 3)} + \frac{3 - 1.5y}{y + 5}[/tex]
x - 3 cancels out:
[tex]\frac{(x+3)}{(y - 5)(y+5)} * \frac{3y(y - 5)}{2x} + \frac{3 - 1.5y}{y + 5}[/tex]
y - 5 cancels out
[tex]\frac{x+3}{y+5} * \frac{3y}{2x} + \frac{3 - 1.5y}{y + 5}[/tex]
[tex]\frac{3y(x+3)}{2x(y+5)} + \frac{3 - 1.5y}{y + 5}[/tex]
Take L.C.M
[tex]\frac{3y(x+3) + 2x(3 - 1.5y)}{2x(y+5)}[/tex]
Open brackets
[tex]\frac{3xy+9y + 6x - 3xy}{2x(y+5)}[/tex]
Collect Like Terms
[tex]\frac{3xy- 3xy+9y + 6x }{2x(y+5)}[/tex]
[tex]\frac{9y + 6x}{2x(y+5)}[/tex]
Factorize:
[tex]\frac{3(3y + 2x)}{2x(y+5)}[/tex]
Hence:
[tex]\frac{x^2 - 9}{y^2 - 25} / \frac{2x^2 - 6x}{3y^2 - 15y} + \frac{3 - 1.5y}{y + 5} = \frac{3(3y + 2x)}{2x(y+5)}[/tex] If [tex]x \ne 0 \ \ or\ y \ne 0[/tex]

Adrian and Nicky earn weekly allowances doing chores over the summer.
•Adrian’s mom pays him $5 each week.
•Nicky’s dad pays her $20 at the beginning of the summer and $3 each week.
Give at least one difference between the graphs and the equations for these 2 situations.
Answer:
To start off, we have a two linear functions to deal with here.
The first starts off at (0,0) and goes linearly up $5 per 1 week or $1.4 per day
The second one starts off at (0,20) and goes linearly up $3 per 1 week or $2.333... per day.
So, the first difference is that Nicky's graph starts higher than Adrian's.
And the second Difference is that Nicky's graph has a lower rate of change than Adrians.
Hope that helped!

A group of children go see a movie. Tickets are $8 each and they split a large popcorn. They spend a total of $34.50.
Please please please explain how you got the answer.
Answer:
Movie tickets cost $5 for children, $8 for adults and $4 for seniors.
The theater earned $1890 in a day. Five times as many adults attended as seniors.
Twice as many children attended as seniors.
Set up and solve a system of equations, to find how many of each type of ticket was sold.
"The theater earned $1890 in a day."
5c + 8a + 4s = 1890
"Five times as many adults attended as seniors."
a = 5s
Twice as many children attended as seniors."
c = 2s
5c + 8a + 4s = 1890
replace c with 2s; replace a with 5s
5(2s) + 8(5s) + 4s = 1890
10s + 40s + 4s = 1890
54s = 1890
s = 1890/54
s = 35 Seniors
then
a = 5(35)
a = 175 adults
and
c = 2(35)
c = 70 children
Step-by-step explanation:
Check solution
70(5) + 175(8) + 35(4) =
350 + 1400 + 140 = 1890; confirms our solutions
answer, 1890
