Find The Volume Of The Cone. Round Your Answer To Two Decimal Places.

Answers

Answer 1

Answer:

Step-by-step explanation:

Volume of the cone, V=1/3*Π*r^2*h

we have the slant height, and we need to find the h, height

a^+b^2=c^2

where c is 13

169=25+h^2

h^2=144

h=12

V=1/3*3.14*25*12=100*3.14=314.15 ft^3

Answer:

The slope PV is:

m = -4

Step-by-step explanation:

Given

P(2, 4)V(3, 0)

Determining the slope of PV

(x₁, y₁) = (2, 4)

(x₂, y₂) = (3, 0)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [0 - 4] / [3 - 2]

               = -4 / 1

               = -4

Thus, the slope PV is:

m = -4

(-4,6), slope=-1

Write the slope-intercept equation using the given information.

Answers

Answer:

y = -x +2

Step-by-step explanation:

y = mx + b

y=6

x=-4

m=-1 (m is the slope)

b=? (b is the y-intercept)

Putting these numbers into this equation,

6 = -1(-4) + b

b=6-4

b=2

So the equation is y = -1x + 2

or just y = -x +2

Step-by-step explanation:

Your friend used the proportion 40/100 = 80/? To find 40% of 80 and says that the answer is 200. Complete the explanation as to why your friend is incorrect and find the correct answer.

Answers

Answer: See explanation

Step-by-step explanation:

My friends calculation is wrong. 40% of 80 is not 200. It is:

= 40% of 80

= 40/100 × 80

= 0.4 × 80

= 32

He should have represented the missing number by x. Therefore,

40/100 = 80/x

Cross multiply

(40 × x) = (80 × 100)

40x = 8000

x = 8000/40

x = 200

A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?

Answers

Answer:

31.25 kg of flour is needed to make 50 cakes

Step-by-step explanation:

A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?

We can find it by using unitary method i.e first find quantity of flour needed for 1 cake and then we can find quantity of flour needed for 50 cakes.

Flour needed to make 4 cakes = 2.5 kg

Flour needed to make 1 cake = [tex]\frac{2.5}{4}[/tex] kg

Flour needed to make 50 cakes = [tex]\frac{2.5}{4}\times 50[/tex]

                                                      = 31.25 kg

So, 31.25 kg of flour is needed to make 50 cakes

The trainers at Atlantis Aquarium perform shows about sea life. Yesterday, they performed 4 shows in 2 hours. Today, they will perform 6 shows. If they perform shows at the same rate, how many hours will the trainers spend performing shows today?

Answers

Answer:

3 hours

Step-by-step explanation:

Number of shows : Time taken

= 4 : 2

Today, they will perform 6 shows.

Number of shows : Time taken

= 6 : x

Equate both ratios to find x

4 : 2 = 6 : x

4/2 = 6/x

Cross product

4 * x = 2 * 6

4x = 12

x = 12/4

x = 3 hours

The trainers will spend 3 hours performing shows today
