A car stereo is on sale for $250 from its original $273 cost. What is the percentage of the discount?
well, from 273 to 250 is 23 bucks, so that's the difference.

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 273&100\\ 23&x \end{array}\implies \cfrac{273}{23}=\cfrac{100}{x}\implies \implies 273x=2300 \\\\\\ x=\cfrac{2300}{273}\implies x\approx 8.42[/tex]
find the value of m and n
Answer:
m = 36
n = 3
Step-by-step explanation:
y varies inversely with x can be written as y ≅ 1/x. As x goes up, y will go down. We need a factor, N, to account for how much change occurs with each step. There needs to be a factor involved, F, to account for how much change occurs with each step.
Calculate the factor by using one of the known points. I'll use (8,9):
y = F/x
9 = F/8
F = 72
The relation becomes y = 72/x. Check this on the other given point, (12,6):
y = 72/x
6 = 72/12 ? YES
Now use y = 72/x to find the two missing points, (m,2) and (24,n):
(m,2) 2 = 72/m, m = 36
(24,n) n = 72/24; n = 3

What is the vertex of y = x2 + 2x +2
O (1,-1)
O (2,-2)
O (1, 2)
0 (-1, 1)
Answer:
vertex = (- 1, 1 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = x² + 2x + 2 ← is in standard form
with a = 1 and b = 2 , then
x = - [tex]\frac{2}{2}[/tex] = - 1
substitute x = - 1 into the equation for y- coordinate of vertex
y = (- 1)² + 2(- 1) + 2 = 1 - 2 + 2 = 1
vertex = (- 1, 1 )
Maribel was working at the fruit stand and had to find how much change to give a customer. The customer bought 11 oranges at $0. 65 each and paid with a $10 bill. Use c to represent the amount of change and choose the correct equation.
Answer:
A) 11(0.65)+c=10
Step-by-step explanation:
Step 1: Calculate the price of 11 oranges at $0.65 each.
11 × 0.65 = $7.15
Step 2: Consider the constraint: if Maribel only has a $10 bill, we have to deduct $7.15 from $10 to find our answer:
$10.00 - $7.15 = $2.85
Step 3: Write an equation based on our solution:
C = 10-0.65x ; Where:
* 10- indicates that we start with $10, and subtract from there.
* C is the amount of change per purchase.
* X is the number of oranges a customer buys.
Answers:
1. The customer receives $2.85 in change.
2. Given a case where a customer pays with one 10-dollar bill, their purchase amount can be calculated with C = 10-0.65x

Step-by-step explanation:
just subtract 400.8-185.2 to get width
Answer:
15.2
Step-by-step explanation:
We know the formula to find the perimeter of a rectangle is 2(w + l) or 2w + 2l (in this case we'll use 2w + 2l). We are given the length as 185.2. Next, we multiply 185.2 by 2 (or add twice) to get 370.4. Then, we subtract 370.4 from 400.8 to get 30.4. Lastly, we split 30.4 in half to get 15.2 meters.

Answer:
$289,169.84 (to the nearest cent)
Step-by-step explanation:
Compound interest is based on the principal amount and the interest that accumulates on it in every period.
Compound Interest = P (1 + r)^n
where P = principal amount, r = annual interest rate (as a decimal), n = term, in years
So for this problem:
P = 185000
r = 1.4 ÷ 100 = 0.015
n = 30
Therefore,
Compound Interest = P (1 + r)^n
= 185000 x (1 + 0.015)^30
= 185000 x (1.015)^30
= 289169.8408...
= $289,169.84 (to the nearest cent)

If I need to achieve 345,000 diamonds in 15 days in a game. How many times do I need to sleep to achieve that goal. Every time you sleep you earn 100 XP, to level up do you need 325 XP, once you level up you get 1800 diamonds.
Answer:
624 times
Step-by-step explanation:
345000/1800=191 2/3, but you can't level up 2/3 of a time, so you round up to 192. Then, you do 192*3.25, because you need to sleep 3 times and then use 1/4 of the XP from the 4th time. This gets you 624
