The graph shows the relationship between the radius and volume for many cones whose height is 6 inches. Select ALL true statements about such cones.

Answers

Answer:

E. If the radius of the cone is 2 inches, the volume of the cone is 25 cubic inches.

B. The relationship between radius and volume is not linear.

Step-by-step explanation:

The true statement regarding the cones should be

If the radius of the cone is 2 inches, the volume of the cone is about 25 cubic inches.

The relationship between radius and volume is not linear.

What is the volume of cone?

The volume of the cone should be equivalent to one-third of the volume of the cylinder that contains a similar radius of the base and height. Here V means the volume, r means the radius and h means the height.

According to the graph, we can say that in the case when the radius should be 2 inches so the volume should be 25 cubic inches. And, the relation between the radius and the volume should not be linear.

Marcus is building a fence around his rectangular backyard. The length of his backyard is 75 3/4 ft, and the width is 81 1/4 ft. If the fence is 3/4 finished, how much fencing is left to complete?

Answers

Answer:

Step-by-step explanation:

Answer:

4,923.75ft²

Step-by-step explanation:

The area of the backyard = Length * width \

Area of the backyard = 75 3/4 * 81 1/4

Area of the backyard = 303/4 * 325/4

Area of the backyard = 6,154.6875ft²

If 3/4 of the fence is finished, the area of the finished part is expressed as;

Finished part = 1/5 * 6,154.6875

Finished part = 1,230.9375ft²

Part left unfinished = 6,154.6875-1,230.9375

Part left unfinished  = 4,923.75ft²

Answer: 235.5

Step-by-step explanation:

75 3/4= 75.75 (L). 81 1/4= 81.25 (W)

Perimeter= 314 3/4 of 314 is 235.5

If cos 0 = 3/5
and angle 0 is in Quadrant IV, what is the value of tan 0 ?
Tan =

Answers

Answer:

-4/3.

Step-by-step explanation:

cos O = 3/5

Using Pythagoras to find the length of the side opposite  the angle O:

As the  cos of O is adjacent/ hypotenuse,  Hypotenuse = 5 , adjacent side = 3 so

opposite side. = sqrt(5^2 - 3^2) = sqrt 16

= 4.

Now the tangent is negative in Q IV so

tan O =  opposite / adjacent side = -4/3

Roberto is 14 years older than Tre. Five years ago, the sum of their ages was 28. How old are they now?

Answers

Answer: Roberto is 26 years old and Tre is 12 years old.

Step-by-step explanation:

Let T=age of Tre

14+T=age of Roberto

14+T+T=28

14+2T=28

2T=14

T=7(Tre’s age 5 years ago)

14+T=14+7=21(Roberto’s age 5 years ago))

7+5=12 years old

21+5=26 years old

To check:

26-12=14

So Roberto is 14 years older.

Answers

Answer:

UV = 4.5 (not rounded)

TV = 3√3

m∠U = 60˚

Step-by-step explanation:

UV = Use sin function since you’re finding the hypotenuse with a given angle and opposite side.

sin(30) = 9/UV

9sin(30) = UV

4.5 = UV

TV = Use Tangent function (opp. over adj.) since you’re finding the adjacent side with a given angle and opposite side.

tan(30) = 9/TV

9tan(30) = TV

3√3 = TV

m∠U = Sum of all interior angles of a triangle is 180˚:

90˚ + 30˚ = 120˚

180˚ - 120˚ = 60˚
