Ok so you know that the person burns 3,600 calories in order to lose a pound. If they burn 240 calories per hour, you would just divide 3,600 by 240 to get 15. Since you asked for minutes just multiply by 60 which is 900.

bulgar [2K]

<u>Answer:</u>

  • The numerator '9's share is 450 and the denominator '7's share is 350.

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

<u>Step-1: Add the ratios:</u>

  • 9 + 7
  • 16

<u>Step-2: Divide 800 by the sum of the ratios:</u>

  • 800 ÷ 16
  • => 50

<u>Step-3: Multiply 50 with each ratio:</u>

  • 9 x 50 = 450
  • 7 x 50 = 350

Hence, <u>the numerator '9's share is 450 and the denominator '7's share is 350.</u>

Hoped this helped.

the sum of the interior angle in a polygon is 40,500° what is the number of sides in the regular polygon
larisa86 [58]

Answer:

227 sides

Step-by-step explanation:

The sum of the interior angles of a convex polygon is S=180(n-2) where n is the number of sides. If S=40500, then we have our equation 40500=180(n-2) and we can solve for n:

40500 = 180(n-2)

225 = n-2

227 = n

Therefore, the number of sides in the regular polygon is 227.

Factor Completely.3g^2-78g+75
Umnica [9.8K]

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ 3g^2 - 78g + 75 factored completely is 3(g-1) * (g-25)

First, write the expression as a difference:

3(g^{2} -26g +25)

Then factor the expression:

3(g^{2} - g - 25g + 25)

Factor the expression again:

3 (g*(g-1)-25(g-1))

Your final answer should be:

3(g-1)*(g-25)

I built a storage shed in the shape of a rectangular box on a square base. The material that I used for the base cost $4 per squ
kumpel [21]

Answer:

side of 6.124 ft and height of 3.674 ft

Step-by-step explanation:

Let's s be the side of the square base and h be the height of the rectangular box.

The base and the roof would have an area of s^2 and cost of

4s^2 + 2s^2 = 6s^2

The sides would have an area of 4sh and cost of 4sh*2.5 = 10sh

So the total cost for the material is

6s^2 + 10sh = 450

10sh = 450 - 6s^2

h = 45/s - 0.6s

The volume of the shed has the following formula

V = s^2h = s^2(45/s - 0.6s) = 45s - 0.6s^3

To find the maximum value for V, we can take its first derivative, and set it to 0

\frac{dV}{ds} = 45 - 1.2s^2 = 0

1.2s^2 = 45

s^2 = 45 / 1.2 = 37.5

s = \sqrt{37.5} = 6.124 ft

h = 45/s - 0.6s = 3.674 ft
