Colton practices the piano 413 minutes in 1 week. If t represents the total time he practices for any number of days, d, write a proportional equation for t in terms of d that matches the context.
Answers
Answer:
lk
Step-by-step explanation:
Answer:
Colton practices 59 minutes each day. So, 413= 59t x 7d.
Step-by-step explanation:
There are 7 days in a week and Colton practices 413 minutes in that amount of time. So to put it simple you just do 413 divided by 7 and you get 59. To check this you can do 59 times 7 and you'll get 413. Then you just put it in the correct equation.

Arwa is playing 'Guess my number'. Arwa says: 'If I add 0.4 to my number, divide the answer by 8, then multiply that answer by 9, I get 0.9.' What is Arwa's number?
Answers
meaning, if you divide 0.9 by 9, you get 0.1. when you multiply 0.1 and 8 you get 0.8. and when you subtract 0.4 from 0.8 you get your answer, 0.4.
Find The value of H:
S=2πr(r+h)
Answers
Answer:
[S / (2πr)] - r = h
Step-by-step explanation:
You can't solve for H because there isn't a capital H in the equation. However, I'm going to pretend its "h" because that might have been a mistake.
S = 2πr(r + h)
Divide by 2πr to try to isolate h
S / (2πr) = r + h
Subtract r from both sides to get h by itself
[S / (2πr)] - r = h
That is your final answer.
\(\\ \rm\Rrightarrow S=2\pir(r+h)\)
\(\\ \rm\Rrightarrow r+h=\dfrac{S}{2\pi r}\)
\(\\ \rm\Rrightarrow h=\dfrac{S}{2\pi r}-r\)
\(\\ \rm\Rightarrow h=\dfrac{S-2\pi r^2}{2\pi r}\)

A new roller coaster just opened at Friday Fun Park. When Lisa got in line, a sign said the wait from that point would be 45 minutes. The actual wait was only 35 minutes. What is the percent error for the park sign's estimate?
If necessary, round your answer to the nearest tenth of a percent.
Answers
Answer: 28.6%
Step-by-step explanation:
To calculate the percent error:
1) Subtract the estimated amount by the actual amount
45-35=10
2) Divide the answer by the actual amount
10/35=0.2857
3) Multiply the answer by 100 to get the percent error
0.2857×100=28.57
Rounded that equals 28.6%
Answer: hope this helps ♡
The percent error for the park sign's estimate is 29%.
Step-by-step explanation:
45 - 35 = 10
(10 out of 35 because it's the actual amount)
10 of 35 in percentage:
(10 ÷ 35) × 100 =
0.28571..... × 100 =
28.5714.....% ≈ 29%

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

6m = 2
m = 1/3
2) 1 - | 3p + 1 | = -3
- | 3p + 1 | = -4
-3p - 1 = -4
-3p = -3 or 3p = -5
p = 1, -5/3
3) | 3x - 2 | = 19
3x = 21 or -3x + 2 = 19
-3x = 17
x = 7, -17/3
4) | 3(x - 2) | = 12
3x - 6 = 12 or -3x + 6 = 12
3x = 18 or -3x = 6
x = 6, -2
The value of m is 1/3 of equation |6m-2|=0, |3(x-2)|=12 of p are 1, -5/3 for equation 1-|3p+1|= -3, value of x are 7, -17/3 for equation |3x-2|=19 and
value of x are 6, -2 for |3(x-2)|=12
The first equation is |6m-2|=0
| 6m - 2 | = 0
6m = 2
Divide both sides by 6
m = 1/3
The value of m is 1/3.
The second equation is 1 - | 3p + 1 | = -3
- | 3p + 1 | = -4
-3p - 1 = -4
Add 1 on both sides
-3p = -3 or 3p = -5
The value of p are 1, -5/3
3) Third equation is | 3x - 2 | = 19
3x = 21 or -3x + 2 = 19
-3x = 17
Divide both sides by 3
The value of x are 7, -17/3
4) | 3(x - 2) | = 12
3x - 6 = 12 or -3x + 6 = 12
3x = 18 or -3x = 6

A college is selling tickets to an upcoming basketball game, and all tickets are the same price. If they sell 4,000 tickets, they will make a total of $237,200 in sales. 1.) What is the price of 1 ticket? 2.) How much money will they make if they sell 9,000 tickets?
Answers
Answer:
1.) $59.30
2.) $533,700
Step-by-step explanation:
Find Unit Price:
237,000/4000= 59.30
Multiply By Unit Price:
59.30x9,000= 533,700
4000t=237200
Divide both sides by 4000 to get your unit price per ticket, which is 59.3.
So this means 1 ticket is $59.30.
To get 9000 tickets money, multiply this by your unit price, which gives $533,700.

A sign says that the price on all music equipment is 30% off the original price. you buy an electric guitar for the sale price of $315.
A-what is the original price?
B-How much money did you save off of the original price?
C-What percent of the original price is the sale price?
Answers
Answer:
Step-by-step explanation:
sale price = original price minus discount.
discount = original price * discount percent / 100.
let s represent the sale price.
let p represent the original price.
let d represent the discount.
let k represent the discount percent.
the above formulas become:
s = p - d
d = p * k/100
we know that s = 315.
we know that k = 30.
formulas become:
315 = p - d
d = p * 30/100
simplify these formulas to get:
315 = p - d
d = .3p
B. $315 - $409.5 = 94.5
C. 70%
Given P(X) = 0.5, P(Y) = 0.4, and P(Y|X) = 0.3, what are P(X and Y) and P(X or Y)?
Answers
Answer:
P(X and Y) =0.2, P(X or Y)=0.7
Step-by-step explanation:
P(X or Y)
P(X∪Y) = P(X)+P(Y) - P(X∩Y)
= 0.5 + 0.4 - 0.2
= 0.7
or 1-P(Y|X)=1-0.3=0.7
P(X and Y)
P(X∩Y) = P(X) × P(Y)
