Since you know that the median is 18 and the two middle values in the set are 17 and B, you know that B must be 19 to make the median 18. Knowing that, you can plug in different values for A that are between 7 and 12 and you would find that only a value of 9 makes the mean 17.

A=9 B=19

The base diameter and the height of a cone are both equal to x units.

HACTEHA [7]

By definition, the volume of a cone is given by:

$V = (\frac{1}{3}) * (\pi) * (r ^ 2) * (h)$

Where,

r: cone circular base radius

h: height of the cone

Substituting values we have:

$V = (\frac{1}{3}) * (\pi) * ((\frac{x}{2}) ^ 2) * (x)$

Rewriting the equation we have:

$V = (\frac{1}{3}) * (\pi) * (\frac{x^2}{4}) * (x)$

$V = (\frac{1}{12}) * (\pi) * (x ^ 3)$

Answer:

An expression that represents the volume of the cone, in cubic units is:

$V = (\frac{1}{12}) * (\pi) * (x ^ 3)$

Note: rewrite the options again.

Please help i dont get this at all

Tom [10]

Answer:

$\frac{20y^{2} a^{2} }{41bx^{3} }$

Step-by-step explanation:

1) Flip the second fraction and change the operation to multiplication:

$\frac{5x^{2}y^{3} }{2a^{5}b^{4} } * \frac{8a^{7}b^{3} }{41x^{5}y }$

2) Cross cancel factors:

$\frac{5y^{2} }{2b } * \frac{8a^{2} }{41x^{3} }$

3) Multiply:

$\frac{40y^{2} a^{2} }{82bx^{3} }$

4) Simplify:

$\frac{20y^{2} a^{2} }{41bx^{3} }$

A department store paint mixer contains 4 pints of equal amounts of yellow and red paint. The shade of red that you want require

Sphinxa [80]

Answer:

8 pints

Step-by-step explanation:

The ratio of red to yellow needs to be ...

red : yellow = 75% : 25% = 3 : 1 = 12 : 4

For the 4 pins of yellow paint in the mixer, a total of 12 pints of red paint are needed. There are already 4 pints in the mixer, so ...

8 pints of red paint need to be added.

A large scoop of ice cream at Tasty Treats ice

Alja [10]

Answer:

$50.24\ \text{inches}^2$ of ice cream is there to eat in this scoop.

Step-by-step explanation:

A large scoop of ice cream at Tasty Treats ice cream Shop has radius of 4 inches. It is required to find how much ice cream is there to eat in this scoop. It means we need to find the area of the ice cream scoop. It is given by :

$A=\pi r^2\\\\A=3.14\times (4)^2\\\\A=50.24\ \text{inches}^2$

So, $50.24\ \text{inches}^2$ of ice cream is there to eat in this scoop.
