Answers

Answer:

15)   C (3, -4)

16)   B (-1, 1)

Step-by-step explanation:

8x + 6y = 0

8x + 2y = 16

8x + 2y = 16

8x = 16 - 2y

x = 2 - 1/4y

8x + 6y = 0

8(2 - 1/4y) + 6y = 0

16 - 2y + 6y = 0

16 + 4y = 0

4y = -16

y = -4

8x + 2y = 16

8x + 2(-4) = 16

8x - 8 = 16

8x = 24

x = 3

________________

-20x - 3y = 17

10x - 4y = -14

-20x - 3y = 17

-20x = 17 + 3y

x = -17/20 - 3/20y

10x - 4y = -14

10(-17/20 - 3/20y) - 4y = -14

-8.5 - 1.5y - 4y = -14

-8.5 - 5.5y = -14

-5.5y = -5.5

y = 1

-20x - 3y = 17

-20x - 3(1) = 17

-20x - 3 = 17

-20x = 20

x = -1

Explain how the volume of a right cone relates to the volume of a cylinder with the same base
and height. Use diagrams and volume formulas to explain the relationship.

Answers

Answer:

its 1/3 of the volume of a cyinder with the same base

Step-by-step explanation:

a pyramid has the same policy with prisms of the same base

Volume is a three-dimensional scalar quantity. If the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.

What is volume?

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Assume a cone and a cylinder such that the radius of the base of both the figures is r units, while the height of the cone and cylinder both is h units.

The volume of the cone with radius r units and height h units now can be written as,

Volume of the cone = (1/3) × π × r² × h units³

The volume of the cylinder with a radius of r units and the height of h units now can be written as,

Volume of the Cylinder = π × r² × h units³

Taking the ratio of the volume of the cone and the volume of the cylinder,

Volume of the cone/Volume of the cylinder = (1/3)πr²h units³ / πr²h units³

Volume of the cone/Volume of the cylinder = 1/3

Volume of the cylinder = 3 × Volume of the cone

Hence, if the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.

Students are auditioning for a school play. Only 18 of the 45 students
auditioning will get a part in the play. What percent of the students
who audition will be in the play?

Answers

it should be 40%, you convert 18/45 to a decimal then multiply by 100

The students who audition will be in the play is 40%

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given that Students are auditioning for a school play

Only 18 of the 45 students auditioning will get a part in the play.

We need to find the percent of the students who audition will be in the play.

45x=18

Divide both sides bby 45

x=18/45

x=0.4

Now multiply with 100 as it is hundredth part

0.4×100=40%

Hence, the students who audition will be in the play is 40%
