Answer:

B will be the answer...

Step-by-step explanation:

The second equation in system B is only in terms of y, so we need to use elimination to eliminate the x term from the second equation in system A.

To do that, we need to multiply the first equation by 5.

5 (-x − 2y = 7)

-5x − 10y = 35

Add to the second equation. Notice the x terms cancel out.

(-5x − 10y) + (5x − 6y) = 35 + (-3)

-16y = 32

Combining this new equation with the first equation from system A will get us system B.

-x − 2y = 7

-16y = 32

A basketball team posts player foul shot ratios: Jon made 18 of 19 Jim got 5/8 in and Joe wrote .94 Who was the better shooter

Leto [7]

Answer:

Jon was the better shooter.

Step-by-step explanation:

Converting the fractions to decimal form will enable us to compare the ratios:

18/19 = 0.9474

5/8 = 0.625

and we have 0.94

So the better shooter was the first one (0.9474) which is Jon.

Find the volume of a cone with a height of 6 in and a base radius of 4 in

Neko [114]

Answer:

The answer is

Step-by-step explanation:

The volume of a cone is given by

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

where

r is the radius

h is the height of the cone

From the question

h = 6 in

r = 4 in

The volume of the cone is

$V = \frac{1}{3} \times {4}^{2} \times 6\pi \\ = \frac{1}{3} \times 16 \times 6\pi \\ = \frac{1}{3} \times 96\pi \\ = 32\pi \\ = 100.530964$

We have the final answer as

100.5 in³
