Answer:

14

Step-by-step explanation:

So For every 3 pencils he buys, he buys 2 pens. The ratio is 3:2. You want to find another ratio that is 21:x, because he bought 21 pencils, but you don't know how many pens. You could also rewrite ratios into fractions so you would get 3/2 = 21/x. Move the variable and get 3/2x=21. So 3/2 multiplied by what is equal to 21? 3/2 multiplied by 14 is 21.

What is the parallel slope intercept form pls help?​
malfutka [58]
<h2>Answer:</h2>

If the line is parallel to the one given, their slopes are the same, so we need to find the y-intercept, then we can determine the slope-intercept form parallel to the given line.

-1 = 4(4) + b\\\\-1 = 16 + b\\\\-17 = b

Now that we have the y-intercept, we can create the equation.

y = 4x - 17

We can prove this by graphing both lines, like so.

Louis built a swimming pool. The depth of the swimming pool is 5 feet. What is the volume of water that it will take to fill the
julia-pushkina [17]

Answer:

For a rectangular prism-like swimming pool: V = w\cdot l \cdot h. V = 360\,ft^{3} when h = 5\,ft, l = 12\,ft and w = 6\,ft.

Step-by-step explanation:

Let assume that swimming pool has a rectangular base and depth is the same  at any point at the bottom. In addition, let w and l be the width and length of the swimming pool. Then, the volume needed to fill the swimming pool is:

V = w\cdot l \cdot h, where h is the depth of the pool.

Let be h = 5\,ft, l = 12\,ft and w = 6\,ft. The volume of the swimming pool is:

V = (6\,ft)\cdot (12\,ft)\cdot (5\,ft)

V = 360\,ft^{3}

Lonna gave away 13/8 pie to her neighbor. Each pie was cut into 8 pieces. How many pieces of pie did lonna give to her neighbor
tankabanditka [31]

Answer:

13 pieces

Step-by-step explanation:

We are given that each pie was cut into 8 pieces .

therefore 1 pie is equal to 8 pieces

1 pie = 8 pieces

Lonna gave 13/8 pie to her neighbor .

So multiply both sides with 13/8 in the above equation in order to make the right side into 13/8 pie and to find the corresponding number of pieces .

1×\frac{13}{8} pie=8×\frac{13}{8} pieces

\frac{13}{8} pie = 13 pieces
