Your answer would be (D) 420

To find this you multiply the miles it can travel in 1 mile by the amount of gallons it has.

Hope this helps!

Which is a simplified form of the expression -4(n + 1) – (n + 2)?
Nadya [2.5K]

Answer:

-(5 n + 6)

Step-by-step explanation:

Simplify the following:

-4 (n + 1) - (n + 2)

-4 (n + 1) = -4 n - 4:

-4 n - 4 - (n + 2)

-(n + 2) = -n - 2:

-4 - 4 n + -n - 2

Grouping like terms, -4 - 4 n - 2 - n = (-4 n - n) + (-4 - 2):

(-4 n - n) + (-4 - 2)

-4 n - n = -5 n:

-5 n + (-4 - 2)

-4 - 2 = -(4 + 2):

-5 n + -(4 + 2)

4 + 2 = 6:

-5 n - 6

Factor -1 out of -5 n - 6:

Answer: -(5 n + 6)

The volume of a soap bubble is 555.4 mm^2 Find the radius and diameter of the soap bubble. Use 3.14 for pi
SashulF [63]

Answer:

radius=11.5

diameter=23

Step-by-step explanation:

The volume of a sphere is V=4/3 Pi r^3

We can use this to solve for the radius.

555.4= 4/3 (3.14)r^3

Solve for r how you would any other equation. Multiply 4/3 and 3.14.

555.4=4.187 r^3

Divide both sides by 4.187

132.65=r^3

To get rid of the ^3, find the cube root of both sides on a calcualtor.

r= 11.5

The diameter is the radius time two.

11.5 (2)=23.

Hope this helps!

Note: When I say both sides, I mean both sides of the = sign.

This is stupid I know lol but I'm having a hard time remembering the difference between a histogram and a bar graph. Can someone
Y_Kistochka [10]

<u>In Bar Graphs;</u>

- Bars have equal space

- One the y-axis, we have numbers & on the x-axis, we have data which can be anything.

<u> In Histograms;</u>

- Bars are fixed

- On the y-axis, we have numbers & and on the x-axis, we have data which in continuous & will always be number.

<u>An easy way you can remember the difference is looking at the spaces of the bars. </u>

<em>A bar graph has gaps</em>

<em>A histogram has no gaps.</em>
