No there will not be enough. Think about it this way. If each slice is 1/4 of the pizza, then each pizza can only feed 4 people. If you have 3 of these pizzas, then you can feed 12 people at most. Since there are 14 kids, you won't have enough.

Giving brainliest for correct awnser. Factor the expression below. <br>​
tresset_1 [31]

Answer:

B. (x + 3) (x + 27)

Step-by-step explanation:

<em><u>To factor the expression, you must split the middle term (18x) into two terms that can be added to get 18, and multiplied to get 81:</u></em>

<em><u /></em>x^2 + 18x + 81

x^2 +3x + 27x + 81

<em><u>Group:</u></em>

<em><u /></em>(x^2 +3x) (27x + 81)

<em><u>Take out GCF (Greates Common Factor):</u></em>

x(x + 3) 27(x + 3)

(x + 27) (x + 3)

The number of gallons of water in a large tank at time (t) minutes is given by the function W(t)=160,000-8,000t+t². Find the ave
sergij07 [2.7K]

The number of gallons of water in the tank at t=10 is

... W(10) = 160,000 -10(8000 -10) = 80100

The number of gallons of water in the tank at t=10.5 is

... W(10.5) = 160,000 -10.5(8000 -10.5) = 76110.25

The rate of change over the interval is

... (W(10.5) - W(10))/(10.5 - 10) = (76110.25 - 80100)/(0.5) = -7979.5

The average rate of change in the number of gallons of water in the tank over the interval is -7979.5 gal/min.

The sign is negative, so the amount of water is decreasing.
