What is solution to the equation 8.25 + 1/4 W equals 10.25 round to the nearest hundredth

Mariulka [41]3 years ago

1/4 = 0.25

8.25 + 0.25w = 10.25
0.25w = 10.25 - 8.25
0.25w = 2
w = 2 / 0.25
w = 8 <===

H(w)=-5x^2+80 to factored form

Answer:

- 5(x - 4)(x + 4)

Step-by-step explanation:

Given

- 5x² + 80 ← factor out - 5 from each term

= - 5(x² - 16) ← x² - 16 is a difference of squares and factors in general as

a² - b² = (a - b)(a + b), thus

x² - 16 = x² - 4² = (x - 4)(x + 4)

Thus

- 5x² + 80 = - 5(x - 4)(x + 4) ← in factored form

100 pts help me please.
Natalija [7]

<u>Answer:</u>

  • Carly's expenditure was $240 and the number of boxes of cards was required is 24 boxes.

<u>Step-by-step explanation:</u>

We know that:

  • 48 + 8(b) = Carly's expenditure
  • 10(b) = Carly's expenditure
  • 48 + 8b = 10b
  • B = Boxes of cards

<u>Work:</u>

  • 48 + 8b = 10b
  • => 48 + 8b - 8b = 10b - 8b
  • => 48 = 2b
  • => b = 24

<u>Now, let's substitute the value of b into any equation.</u>

  • 10(24)
  • => 240

<u>Hence, Carly's expenditure was $240 and the number of boxes of cards was required is 24 boxes.</u>

Hoped this helped.

Find the volume of a right circular cone that has a height of 10.7 in and a base with a diameter of 8.1 in. Round your answer to
scoundrel [369]

Answer:

V = \pi r^2 h

And for this case the value for the height is h = 10.7 in the diameter is provided D = 2r = 8.1 in so then the radius is given by:

r = \frac{D}{2}=\frac{8.1 in}{2}= 4.05 in

Then we can find the volume with the first formula and replacing we got:

V = \pi (4.05in)^2 (10.7 in)= 551.4 in ^3

The final answer for this case would be 551.4 cubic inches

Step-by-step explanation:

The volume for a right circular cone is given by this formula:

V = \pi r^2 h

And for this case the value for the height is h = 10.7 in the diameter is provided D = 2r = 8.1 in so then the radius is given by:

r = \frac{D}{2}=\frac{8.1 in}{2}= 4.05 in
