Answer:

The answer is x= 19980

Step-by-step explanation:

You do 540 = x/37 ---> then divide by 1/37 on each side and you get --> 19980 = x ---> you can plug it back in and get the right answer. 540 = 19980/37 = --------> 540=540

Answer:

(2x+7)+4

Step-by-step explanation:

Anytime it says number of units left is a +7.

And it goes in the parentheses or absolute

Answer:

We have the relation:

1ft = 12 inches.

Then, if we cube both sides, we have:

(1ft)^3 = (12 in)^3

1ft^3 = 288 in^3.

Now we know that:

The bucket is 864 in^3

The tank is 7 ft^3.

knowing that 1 ft^3 = 288in^3

Then 7 ft^3 is seven times that:

7ft^3 = 7*(1ft^3) = 7*(288in^3) = 2016 in^3

Now the number of buckets needed to completely fill the tank is:

N = (2016 in^3)/(864in^3) = 2.33

So you need 2.33 buckets, or we can round it up to 3 buckets, where the third bucket will have some water inside it when the tank is completely filled.

Answer:

vol. = 414.7 in³

Step-by-step explanation:

given:

A cone has a radius of 6 inches and a height of 11 inches.

find:

What is the volume of the cone?

volume of a cone = ¹/₃ π r² h

where r = 6 in.

h = 11 in

plugin values into the formula:

vol. = ¹/₃ π (6)² 11

vol. = 414.7 in³

414.48 inches³

Volume formula

V = Ab×h/3

Ab = πr²

V = πr²×h/3

= 3.14(6in)²×11in/3

= 3.14×36in²×11in/3

= 1243.44in³/3

= 414.48 inches³

The value of the function for x=-1 is 3.

The given function is [tex]f(x)=x^{5} +(x+3)^{2}[/tex].

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

From the table, we get coordinates as (-2, -31), (-1, y), (0, 9) and (1, 17).

To find the y value of the coordinate (-1, y), substitute x=-1 in the given function.

That is, [tex]f(-1)=(-1)^{5} +(-1+3)^{2}=3[/tex]

Therefore, option D is the correct answer.
