The student council at Greenwood High School is making T-shirts to sell for a fundraiser, at a price of $18 apiece. The costs, meanwhile, are $10 per shirt, plus a setup fee of $40. Selling a certain number of shirts will allow the student council to cover their costs. How many shirts must be sold?
Answer:
Costs are $490
49 shirts are sold
98 + 8x = 10x
98 = 2x
49 = x
98 + 8(49) = $490 in costs
49 shirts sold
Step-by-step explanation:
98 + 8x = 10x
98 = 2x
49 = x
98 + 8(49) = $490 in costs
49 shirts sold

Jamal is solving the equation 2x2+7x−5=0 with the quadratic formula.
Which values could he use for a, b, and c?
a = -2, b = -7, c = 5
a = 2, b = 7, c = -5
a = 2, b = -7, c = -5
a = 2, b = 7, c = 5
Answer:
a = 2, b = 7, c = -5
Step-by-step explanation:
Hi, I took the test and this is the answer. If its K12 then I'm 100% its correct.
The values that can be use for a, b and c in the equation 2x² + 7x − 5 = 0 are a = 2, b = 7, c = -5
Quadratic equation formulaThe quadratic equation formula is represented as follows:
ax² + bx + c
where
a, b and c are unknown numbers. a is not 0x = unknownTherefore, lets model the equation to 2x² + 7x − 5 = 0 to ax² + bx + c
Hence,
a = 2
b = 7
c = -5

3 1/3 divided by 2/3
pls help me!!!! im stuck and pls show your work!
Answer:
5
Step-by-step explanation:
Since this is division for a fraction, you do keep, change, flip.
First, you keep the first fraction.
3 1/3 ÷ 2/3
Then, you flip the ÷ to a ×.
3 1/3 × 2/3
Next, you flip the 2nd fraction.
3 1/3 × 3/2
Now you can make the mix number an improper fraction.
10/3 × 3/2
Finally multiply across.
10/3 × 3/2 = 30/6
Simplify.

I need to use the power rule (if m and n are real numbers and x doesn't equal 0, then (x^m)^n = x^mn... ) to simplify this fraction: (2x^2 y^-2 / y^5)^-3
Answer:
[tex]= 2x^{-6}y ^{21}\\\\[/tex]
Step-by-step explanation:
Given the indicinal expression (2x^2 y^-2 / y^5)^-3
In indices
[tex](x^m)^n = x^{mn[/tex]
Applying to solve the question
[tex](2x^2 y^{-2} / y^5)^{-3}\\\\= \frac{2x^{-6}y^6}{y^{-15}}\\= 2x^{-6} * \frac{y^6}{y^{-15}} \\= 2x^{-6} * y ^{6-(-15)}\\= 2x^{-6} * y ^{6+15}\\= 2x^{-6} * y ^{21}\\= 2x^{-6}y ^{21}\\\\[/tex]

Step-by-step explanation:
If the square below is enlarged by a scale factor of 2, what will be the area of the new square? 184 square units 188 square units 192 square units 196 square units
Answer:
256square units
Step-by-step explanation:
Since we are not given a diagram. Let us assume the side length of the given square is 8 units
If the the square is enlarged by a scale factor of 2, the side length of the new square will be 2 * 8 = 16units
Since area of a square = L²
Hence the area of the new square = 16²
area of the new square = 256 square units
Hence the area of the new square is 256square units
Note that the side length of the original square was assumed. The values can change depending on the side length of the original square before enlargement
anyone know this ???
Answer:
? = 13
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
?² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )
? = [tex]\sqrt{169}[/tex] = 13
Answer:
13
Step-by-step explanation:
If we use the Pythagorean theorem we have
hypothenuse^2 = 12^2 + 5^2 = 144 + 25 = 169
hypothenuse = √169 = 13
Write the equation of the line PARALLEL to the line y = 4x - 9 that passes through the
point (-2, 4)
Answer:
y = 4x + 12
Step-by-step explanation:
The slope of the line y = 4x - 9 is 4.
The slope of the line we are looking for is also 4.
y - y1 = m(x - x1)
y - 4 = 4[x - (-2)]
y - 4 = 4(x + 2)
y - 4 = 4x + 8
y = 4x + 12
Answer: y = 4x + 12

Find the loan-to-value ratio for a home appraised at $583,620.00 that the buyer will purchase for $585,000.00. The buyer plans to make a down payment of $175,000.00.
Step-by-step explanation:
Calculating your loan-to-value ratio
Current loan balance ÷ Current appraised value = LTV.
Example: You currently have a loan balance of $140,000 (you can find your loan balance on your monthly loan statement or online account). ...
$140,000 ÷ $200,000 = .70.
Current combined loan balance ÷ Current appraised value = CLTV.

The total cost of the studio apartment is $140,000.
The down payment is $28,000.
Percentage of down payment to purchase price is:
= 28,000 / 140,000 * 100%
= 20%
b. Percentage of down payment of $63,000 to purchase price is:
= 63,000 / 140,000 * 100%
= 45%
