Answer:

The correct answer is A. 10 - 2

Step-by-step explanation:

1. Let's make all the comparisons for the four alternatives:

A. 3 + 7 > 10 - 2 ⇒ 10 > 8, the comparison is correct because 10 is bigger than 8.

B. 3 + 7 > 9 + 4 ⇒ 10 > 13, the comparison is not correct because 10 is less than 13.

C. 3 + 7 > 7 + 3 ⇒ 10 > 10, the comparison is not correct because 10 is equal to 10.

D. 3 + 7 > 8 + 2 ⇒ 10 > 10, the comparison is not correct because 10 is equal to 10.

The only correct comparison is A. 10 - 2.

Cone A has a radius of 2 inches and a height of 3 inches. In cone B, the height is the same, but the radius is doubled. Calculat

wlad13 [49]

Answer: Option C.

Step-by-step explanation:

Use the formula for calculate the volume of a cone:

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

Where r is the radius and h is the height.

Volume of the cone A:

$V_A=\frac{1}{3}\pi (2in)^2(3in)=12.56in^3$

Volume of the cone B:

If the height of the cone B and the height of the cone A are the same , but the radius of the cone B is doubled, then its radius is:

$r_B=2r_A\\r_B=2*2in\\r_B=4in$

Then:

$V_B=\frac{1}{3}\pi (4in)^2(3in)=50.26in^3$

Divide $V_B$ by $V_A$ :

$\frac{V_B}{V_A}=\frac{50.26in^3}{12.56in^3}=4$

Therefore: When the radius is doubled, the resulting volume is 4 times that of the original cone.

Solve for x and y 8x-2y=24

TiliK225 [7]

Answer: For y it's y=4x−12 and for x it's x=12+y/4

Step-by-step explanation:

SOLVING FOR X

8x-2y=24

2(4x−y)=24

4x−y=24/2

4x−y=12

4x=12+y

x=12+y/4

SOLVING FOR Y

8x-2y=24

2(4x−y)=24

4x−y=24/2

4x−y=12

−y=12−4x

y=−12+4x

y=4x−12

Hope this helps, have a BLESSED AND WONDERFUL DAY! As well as a great Black History Month and Valentine's day! :-)
