Answer:

n = $\frac{4}{3}$

or (because the wording is kind of confusing)

n = $\frac{20}{3}$

Step-by-step explanation:

9(4 - n) = 24

36 - 9n = 24

-9n = -12

n = $\frac{4}{3}$

or (because the wording is kind of confusing)

9(n - 4) = 24

9n - 36 = 24

9n = 60

n = $\frac{20}{3}$

Find the value of (-8)(-3)(-2)(4). A.17 B.-17 C.192 D.-192 helppp

julsineya [31]

Note: two negatives multiplied together = one positive answer
one negative & one positive multiplied together = one negative answer
Multiply -8 and -3 together

-8(-3) = 24
24(-2) = -48
-48(4) = -192

D) -192 is your answer

hope this helps

Answer:

1. 4.7

2. 5,082

Step-by-step explanation:

1. To find the volume of a cone you use this formula $V=\pi r^{2} \frac{h}{3}$ . The diameter is 3 so to find the radius, divide it by 2 (3/2=1.5) and we know the height. Input the numbers into the formula and solve $V=\pi (1.5)^{2} \frac{4}{3}$ which is equal to $3\pi$ . To find HALF, divide that answer by 2. $3\pi /2= 4.71239$ , round to the nearest tenth, making the answer 4.7!

2. To find the volume of a rectangular prism you use $V=lwh$ . Input the numbers, $V=(30)(12)(16)$ to find the amount of water for the bigger tank (5,760). Now follow the same process to find the amount of water for the smaller tank $V=(12)(6)(9)$ which is 678. Now subtract the smaller tank amount (678) from the larger tank since you're taking the water from the bigger tank to fill the smaller one which equals 5,082.
