What is the total cost if the shirt cost $40 and 20% off

1 answer:

7 0

You'd simply have to find 20% of $40. To find the percent of a number, you would change the percent into an actual decimal/number, and then multiply them both. So the percent would become 0.20.

40 × 0.20 = 8

So now you would subtract 8 from the cost of 40.

40 - 8 = 32.

The shirt costs $32.

Write the quadratic equation whose roots are

maks197457 [2]

The quadratic equation $y = ax^2 +bx+c$ can be written in the form:
$y = a(x-p)(x-q)$
Where p and q are the roots of the equation.
Given p = 4, q = -2, a = 3, the quadratic will look like this:
$y = 3(x-4)(x+2)$
Finally, distribute and combine like terms to put it in standard form.
$y = 3(x^2 - 4x+2x -8) \\ \\ y = 3(x^2 -2x-8) \\ \\ y = 3x^2 -6x -24$

You sell soup mixes for a fundraiser. For each soup mix you sell, the company that makes the soup receives x dollars l, and you

Whitepunk [10]

Answer: $ 6

Step-by-step explanation:

Here, the cost price of each soup = x dollars

The cost price of 16 soup = 16 x

The selling price of 16 soup = 16 x + 96

Since, the total money received for 16 soup = The selling price of 16 soup - The cost price of 16 soup

= 16 x + 96 - 16 x

= 96

Thus, the total money received for 16 soup = 96 dollars

⇒ The total money received for 1 soup = $\frac{96}{16}$ dollars

⇒ The total money received for 1 soup = 6 dollars

Hence, for each soup 6 dollars is received.

I will mark you brainiest if you can answer this

Korvikt [17]

Answer:

12^4 or 20736

Step by Step Instructions:

really all you have to do is subtract the exponents. 12^7-12^3=12^4, if you want to expand the numbers you can do it that way too. 12^7=35831808, 12^3=1728, 35831808/1728=20736 (which is the same as 12^4)

I don’t really get this question can someone help me out

Inessa [10]

angles EFH and GFH are congruents

for the second equivalence criterion two triangles are equivalents if they have respectively 2 angles and 1 side congruents

the two triangles have congruents the angle right angle (HGF and HEF) and the 55 degrees angles (EFH and GFH); then they have in common the HF side.

so the triangles are congruent and so all the sides are respectively congruent,for example EH with HG:

EH=HG

s+36=7s

s+36-7s=0

s-7s=-36

-6s=-36

6s=36

s=6
