Answer:

For Friday, 22% of the check in's happened on that day. For Saturday, 24% of the check in's happened on that day. For both days combined, 46.66% of the check in's happened for both.

Step-by-step explanation:

Overall there were 90 check ins. Since 20 happened on Friday, it would be 20/90, which is 22%. Saturday, 22 check ins happened, so it would be 22/90, which is 24%. Overall, between Friday and Saturday, 42 check in's happened, so it would be 42/90, which is 46.66%.

Ms. Durham makes delicious chili. Each batch makes about 900 in^3 of chili. Will a crockpot that is 15 inches high and a diamete

Mashutka [201]

Answer:

Volume of the Crockpot = πr^2h

= 3.14 x 6 x 6 x 15

= 3.14 x 540 in^3

Volume of double batch of chili = 900 x 2 = 1800 in^3

3.14 x 540/1800 = 9.42/10 = 0.942 < 1

Since the value we found by dividing the volume of Crockpot by double batch of chili is less than 1, we can say that the Crockpot will not hold the double batch of chili

Hope this helps!

Answer:

2x^2 + x - 6 = rectangular garden: length = 2x – 3 feet; width = x + 2 feet

Step-by-step explanation:

(2x - 3)(x + 2) = 2x^2 + x - 6 =

2x^2 + 4x - 3x - 6 = 2x^2 + x - 6 =

2x^2 + x - 6

You get the original equation from the two sides multiplied. :)

Nimfa-mama [501]

Answer:

30 trees

Step-by-step explanation:

Given the policy:

8 trees are cut down 48 trees will be planted

If homeowner is going to cut down five trees on his property how many trees will be planted

Since :

8 trees cut down = 48 planted

5 trees cut down = X

Cross multiply :

8 * X = 48 * 5

8X = 240

X = 240/8

X = 30

Hence, 30 trees will need to be planted
