Footballs sell for $27.99 each at Dicks Sporting Goods and $21.59 each at Big 5. If the coach buys a dozen footballs, how much c

klasskru [66]

Answer:

The money he can save by buying them at Big 5 is $76.80.

Step-by-step explanation:

Given:

Footballs sell for $27.99 each at Sporting Goods.

Footballs sell for $21.59 each at Big 5.

The coach buys a dozen footballs.

Now, to find the amount he save by buying them at Big 5.

So, first we find the cost of footballs at Sporting Goods and at Big 5.

1 Dozen = 12 pieces.

Thus, the cost of footballs at Sporting Goods =

$\$27.99\times 12 =\$335.88$

And, the cost of footballs at Big 5 =

$\$21.59\times 12=\$259.08.$

Now, to get the amount coach can save by buying them at Big 5, we subtract both the cost as the cost of Sporting Goods is more than the Cost of Big 5:

The amount coach can save by buying them at Big 5 =

$\$335.88-\$259.08=\$76.80.$

Therefore, the amount he can save by buying them at Big 5 is $76.80.

I will mark as brainiest

If two triangles are similar, then their side lengths are proportional.

RS / JK = RT / JL

5 / x = 4 / 7

4x = 35

x = 35/4 = 8.75

RT / JL = TS / LK

4 / 7 = 6 / (y + 2)

42 = 4(y + 2)

42 = 4y + 4

4y = 38

y = 38/4 = 9.5

LK = 9.5 + 2 = 11.5 cm

JK = x = 8.75

Hope this helps!

Find x in this 45°-45°-90° triangle.<br><br><br><br> x =

Zielflug [23.3K]

Use a^2 + b^2 = c^2

the triangle must be isosceles because the two angles are the same

1.2^2 + 1.2^2 = x^2
1.44 + 1.44 = x^2
2.88 = x^2
x=6√2/5
or
x ≈1.69706

The gcf of two numbers less than or equal to 12 is 2. Their LCM is 20.What are the numbers?

bixtya [17]

We know:

$LCM(a,\ b)=\dfrac{ab}{GCF(a,\ b)}$

We have

$GCF(a,\ b)=2,\ LCM(a,\ b)=20,\ a\leq12,\ b\leq12$

Substitute:

$20=\dfrac{ab}{2}\qquad|\cdot2\\\\ab=40$

$40=1\cdot40=2\cdot20=4\cdot10=5\cdot8$

Only 4 and 10 meet the requirements of the question.

--------------------------------------------------------------------

40 and 1 NOT, because 40 > 12

20 and 2 NOT, because 20 > 12

5 and 8 NOT because GCF(5, 8) = 1

For problems 29 - 31 the graph of a quadratic function y=ax^2 + bx + c is shown. Tell whether the discriminant of ax^2 + bx + c

Elan Coil [88]

Answer:

29) discriminant is positive

30) discriminant is 0

31) discriminant is negative

Step-by-step explanation:

the graph of a quadratic function y=ax^2 + bx + c is shown. Tell whether the discriminant of ax^2 + bx + c = 0 is positive, negative, or zero.

In the graph of question number 29 we can see that the graph intersects the x axis at two points

so the equation has 2 solutions.

When the equation has two solution then the discriminant is positive

In the graph of question number 30 we can see that the graph intersects the x axis at only one point

so the equation has only 1 solution.

When the equation has only one solution then the discriminant is equal to 0

In the graph of question number 30 we can see that the graph does not intersects the x axis

so the equation has 2 imaginary solutions.

When the equation has two imaginary solutions then the discriminant is negative
