The correct option is :  60 ft^3

<u><em>Explanation</em></u>

Suppose, the volume of the fish tank is V ft³

The density of the fish tank is 0.5 fish/ft³. It means, <u>the number of fish in 1 ft³ volume is 0.5</u>

So, the number of fish in V ft³ volume will be: 0.5V

Given that, there are 30 fish in the tank. So, the equation will be......

0.5V=30\\ \\ V=\frac{30}{0.5}=60

Thus, the volume of the tank is 60 ft³

Ƒ(x) = x − 9 if the domain is (3, -3, 0)
amid [387]

Answer:

f(3) = -6

f(-3) = -12

f(0) = -9

Step-by-step explanation:

Substitute each number for x.

f(3) = 3 - 9 = -6

f(-3) = -3 - 9 = -12

f(0 ) = 0 - 9 = -9

Geometric Probability
KiRa [710]

Answer:

Step-by-step explanation:

1) P= Area of Circle/ Area of large rectangle

Area of the circle = pi·r² = pi·2²=4 pi ft.²

Area of large rectangle=  l·w -12·10 =120 ft.²

P = 4pi/120 rewrite 120 as 4·30

P= 4 pi/4*30 = pi/30 = 3.14/40 ≈ .1047 ≈10% (because .1047·100 =10.47≅10)

2) P = Area of smaller rectangle/ Area of large rectangle

Area of smaller rectangle = l·w = 2·4 =8 ft.²

Area of large rectangle=l·w = 12·10=120 ft²

P= 8/120 ≅ .0666≅ 7% (because .0666·100 =6.66≅7)

3) P= Not the circle or smaller rectangle/ Area of large rectangle

Not the circle or smaller rectangle area

= Area of large rectangle - Area of circle -Area of smaller rectangle

= 120 -4·pi -8 = 120 - (4· 3.14) -8 = 99.4362939 ft²

Area of large rectangle = l·w = 12·10 =120 ft²

P = 99.4362939 /120 ≅ .8286 ≅83% (because .8286·100 =82.86≅83)

A box of jerseys for a pick-up game of basketball contains 9 extra-large jerseys, 6 large jerseys, and 5 medium jerseys. If you
aleksley [76]

Answer:

1/114 or 0.008772

Step-by-step explanation:

I am not very sure, my answer seems unlikely, but here's what I think:

There are 20 jerseys in the box to begin with, and 5 medium jerseys that you can have.

Therefore, the probability of you randomly grabbing a medium sized jersey is 5/20 or 1/4.

After taking out one medium sized jersey, there are 19 jerseys in the box and 4 medium jerseys you can pick from.

The probability of you randomly grabbing a medium sized jersey is 4/19.

After taking out another medium sized jersey, there are 18 jerseys left in the box and 3 medium jerseys you can pick from.

The probability of you randomly grabbing a medium sized jersey is 3/18.

To get the answer, you do 1/4 * 4/19 * 3/18, and get 1/114, or 0.00877192982.

If you round that to the nearest millionth, it's 0.008772

Don't judge me, it might not be correct.

The school printer has purchased a new color printer that can produce 75 pages in 5 minutes. If the printer were to print only 1
lawyer [7]

Answer:

15 pages

Step-by-step explanation:

This is a fairly simple problem meaning it has very few steps. If it makes 75 pages in 5 minutes you need to find out what the PPM or Page Per Minute is.

To find that you simply divide 75 by 5 and get 15 and in one minute the printer prints 15 pages.

Easy points
goblinko [34]

Answer: 2

Step-by-step explanation:

try each value in the equation

2(0) + 1 = 3

0 + 1 = 3

1 ≠ 3

so 0 doesn’t work

2(1) + 1 = 3

2 + 1 = 3

3 = 3

this works, so the answer is 1
