Francis went to the sporting goods store and spent $75.15 on 6 items.
MArishka [77]

Answer:

$6.03

Step-by-step explanation:

The question is asking us how much each pair of socks cost. With the information we are given, we know that there are 5 pairs and that they all cost the same amount. If the total were just the 5 socks, we could easily divide the total by 5 to get the price of each pair but that's not the case. The soccer ball is included in the final cost. To overcome this, we just have to subtract the soccer ball's cost ($45) from the total.

So we subtract $45 from $75.15, giving us $30.15, the total amount of all the socks. However we need to find out how much each pair costs and there are 5 of them, so we divide 30.15 by 5. This gives us the answer, $6.03.

Each pair of socks cost $6.03.

Simpler Explanation:

  • $75.15 - $45 = $30.15
  • $30.15 / 5 = $6.03

The answer is $6.03

Please help asap with this question i will give brainliest.
HACTEHA [7]

Answer:

D

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = ( - \frac{1}{5}, \frac{1}{3} ) and r = \frac{1}{2}, thus

(x - (- \frac{1}{5} ))² + (y - \frac{1}{3} )² = ( \frac{1}{2} )², that is

(x + \frac{1}{5} )² + (y - \frac{1}{3} )² = \frac{1}{4} → D

If gas is $2.45 and you pay $ 12.00 how many gallons of gas do you get ?
attashe74 [19]
Gas is 2.45 per gallon.  So if we pay $12 we get 12÷2.45 gallons:

12 ÷ 2.45 ≈ 4.90 gallons.

You get roughly 4.90 gallons.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Alenkasestr [34]

Answer:

A = -10

Step-by-step explanation:

x^2 + 10x + 24 = 0

To find the roots, we need to factor the equation.

What 2 numbers multiply to 24 and add to 10

6*4 = 24

6+4 = 10

(x+6) (x+4)=0

Using the zero product property

x+6 = 0  x+4 = 0

x = -6   x = -4

We want the sum when the roots are added

-6+ -4 = -10
