John the car salesman makes a commission on selling cars, as a percentage of the price, which

Bess [88]

Answer:

John's commission percentage on new cars is x and his commission percentage on used cars is 1.5x, therefore, John's commission percentage on new cars is 2% and his commission percentage on used cars is 3%.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

John's commission percentage on new cars = x

John's commission percentage on used cars = x + 50%x (His commission on used cars is 50% more than on new cars)

Sales on new cars = $80,000

Sales on used cars = $50,000

John's commission check = $3,100

2. If x represents the commission percentage on new cars, express the commission percentage on used cars in terms of x.

John's commission percentage on new cars = x

John's commission percentage on used cars = x + 50%x = 1.5x

Now we can solve for x, this way:

80,000x + 50,000 * 1.5x = 3,100

80,000x + 75,000x = 3,100

155,000x = 3,100

x = 3,100/155,000

x = 0.02 = 2% ⇒ 1.5x = 3%

John's commission percentage on new cars is 2% and his commission percentage on used cars is 3%

The line plot shows the number of bags of grapes,grouped by weight, to the nearest 1/8 pound. How many bags of grapes had a weig

Assoli18 [71]

Answer:

2.25 pounds

Step-by-step explanation:

The diagram showing the weight of bags with grapes is shown in the attached file below.

From the diagram; number of bags of grapes that had a weight of $\dfrac{3}{8}$ pounds or less is:

$\dfrac{3}{8}$ pounds = 3

$\dfrac{1}{4}$ pounds = 4

$\dfrac{1}{8}$ pounds = 1

Thus; the total is = 3+4+1 = 8

However, The total weight of the grapes in the bag that had a weight of $\dfrac{3}{8}$ pounds or less is :

= $\dfrac{3}{8}(3) + \dfrac{1}{4}(4) + \dfrac{1}{8}(1)$

= $\dfrac{9}{8} + 1 + \dfrac{1}{8}$

= $\dfrac{9+8+1}{8}$

= $\dfrac{18}{8}$

= 2.25 pounds

Mags is 2 years older than vector. Which equation will help you find mags age (m) if you know vectors age (v)

Ostrovityanka [42]

Answer:

m=v+2

Step-by-step explanation:

So Mags (m) is older than vector (v) so matter what m is just v+2 the two is how much older mags is.

Hope this helps, have a good day :)

A cyclindrical water tank has a radius of 6 feet and a height of 20 feet. A larger tank with the same height has a volume that i

xz_007 [3.2K]

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=6\\
h=20
\end{cases}\implies V=\pi 6^2(20)\implies \stackrel{\textit{smaller cylinder}}{V=720\pi }$

since the smaller tank has a volume of 720π, then the larger tank has a volume of 3 times that much or 3*720π, or 2160π, and its height is the same as the smaller one's, 20.

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
V=2160\pi \\
h=20
\end{cases}\implies 2160\pi =\pi r^2(20)\implies \cfrac{2160\pi }{20\pi }=r^2
\\\\\\
108=r^2\implies \sqrt{108}=r\implies 6\sqrt{3}=r
\\\\\\
\stackrel{\textit{and since the \underline{d}iameter is twice the radius}}{d = 2r\implies d=12\sqrt{3}}$
