Answer:

1/2 and 9/14

Step-by-step explanation:

Let the first fraction be 1/2

Let the second fraction be x

1/2 + x= 8/7

x= 8/7-1/3

= 16-7/14

= 9/14

Hence the two numbers are 1/2 and 9/14

The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of

Jet001 [13]

Answer:

900 cubic inches.

Step-by-step explanation:

Given the following data

Volume of right circular cone = 300in³

We know that the volume of a right circular cone is given by the formula;

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

Where;

V is the volume of right circular cone.

r is the radius of the base of the right circular cone.

h is the height of the right circular cone.

The volume of a right circular cylinder is given by the formula;

$V = \pi r^{2}h$

Thus, multiplying the volume of the right circular cone by 3 would give us the volume of the right circular cylinder.

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

Substituting into the equation, we have;

V = 300 * 3

V = 900in³

Therefore, the volume of a right cylinder that has the same base and height as the cone is 900 cubic inches.

Twice the difference of a number and 9 is at least 17.

victus00 [196]

Answer:

x ≥ 12.5

Step-by-step explanation:

2(x-9) ≥ 17---Use Distributive Property

2x-18 ≥ 17

2x-18+18 ≥ 17+18

2x ≥ 25

2x/2 ≥ 25/2

x ≥ 12.5

I need the value of y -2(4 + 3y) = -2(4 + y)

Dafna11 [192]

Answer:

y=0

Step-by-step explanation:

-2(4+3y)=-2(4+y)

-8-6y=-8-2y

+8 +8

-6y=-2y

+2y +2y

-4y=0

-4y/-4=0/-4
