The Figure Is Made Up Of Hemisphere And A Cylinder.what Is The Exact Volume Of The Figure?box [] Cm^3

Answers

Answer 1

Answer:

Data: (Cylinder)

h (height) = 8 cm

r (radius) = 5 cm

Adopting:

V (volume) = ?

Solving:(Cylinder volume)

Note: Now, let's find the volume of a hemisphere.

Data: (hemisphere volume)

V (volume) = ?

r (radius) = 5 cm

Adopting:

If: We know that the volume of a sphere is , but we have a hemisphere, so the formula will be half the volume of the hemisphere

Formula: (Volume of the hemisphere)

Solving:

Now, to find the total volume of the figure, add the values: (cylinder volume + hemisphere volume)

Volume of the figure = cylinder volume + hemisphere volume

Volume of the figure = 628 cm³ + 261.6 cm³

Step-by-step explanation:

6.

a.

(10/3)*(14/9)*(9/4)

= 11 2/3

b.

Yes, because the volume of the shed is about 11.67 yards long, the 10 yards of wood will fit in the shed.

For this one, we have to break it into two pieces.

(I made them into a small box and and big box)

The measurements of the small box are 7*5*6.

The measurements of the big box are 20*5*9.

Using this information, we can make the following equation and solve it quickly.

(7*5*6) + (20*5*9)

(210) + (900)

1,110

Thus, the volume of this box is 1,110 in. ^2

Cole has a rectangular garden with an area of 16.02 square meters. What is the width, in meters, of the garden?

Answers

Answer:

3.56m

Step-by-step explanation:Parameters given:

Area of the rectangular garden = 16.02m^2

Length of the rectangular garden = 4.5m

The Area of a rectangle can be calculated for using the formula below

Area (square meters) = length (meters) × width (meters)

Therefore, 16.02m^2 = 4.5m × width

Width = 16.02m^2 / 4.5m

Width = 3.56m

Therefore the width in meters of the garden is 3.56m

See the attachment below for an illustrative diagram

A = area

l = length

w = width

16.02 divided by 2 = 8.01

Which are equivalent ratios to 2:3?
Check all that are true.

10:16

8:12

6:9

9:12

4:6

Answers

Answer:

8:12 6:9 4:6

Step-by-step explanation:

Divide each ratio by 2:3 and check if both numbers on either side of : are the same

For example:

8:12 divided by 2:3 = 4:4

Answer:

8:12, 6:9, and 4:6

Step-by-step explanation:

Equivalent ratios are any ratios that represent the same when they are simplified. All the ratios above simplify to 2:3. When the 8 and 12 of 8:12 are both divided by 4, the result is 2:3. When the 6 and 9 in 6:9 are both divided by 3, the result is 2:3. When the 4 and 6 in 4:6 are both divided by 2, the result is 2:3. The ratios 10:16 and 9:12 cannot be simplified to 2:3, and therefore are not correct answers.

Specifically, give the quotient and the remainder for the associated division and the value of P(−2).

-The Answer should have the Quotient and Remainder for points.

Answers

Answer:P(2) = 2(2)³ - 2(2)²- 3

= 16 - 8 - 3

= 5

Remainder or value of P(2) = 5

Quotient =   (2x³- 2x² - 3)/ x-2 = 2x² + 2x + 4

Step-by-step explanation:

Answer:

P(2) = 2(2)³ - 2(2)²- 3

= 16 - 8 - 3

= 5

Remainder or value of P(2) = 5

Quotient =   (2x³- 2x² - 3)/ x-2 = 2x² + 2x + 4

Hank is throwing a surprise party. The party costs $20 per person. Create an equation and graph to represent the relationship between the cost of the party and the number of friends attending.

Complete the following table:

Number of friends (f) 5 10 15 20
Cost of party (c) 100 200 300 400

Plots the points from the table onto the graph.

Answers

Answer: Answer with Step-by-step explanation:

Since we have given that

Cost of party per person = $20.

Let the number of friends be 'f'.

Let the cost of party be 'p'.

According to question, our equation becomes

p= 2f

So, if p = 100, then f = p/2 = 100/2 = 50 if f = 10, then, p = 2f = 2 • 10 = 20 If p = 300 then, f = 300/2 = 150, If f = 20, then, p = 2f = 2 • 20 = 40 So, Table as follows:

Number of friends cost of party

50 100

10 20

150 300

20 40

A function f(x) is shown below.

f(x) = x + x + x

Write an equivalent form of f(x) in function notation that contains only one term on the right side of the equation.

Answers

Answer:

f(x) = 3x

Step-by-step explanation:

when adding x (the same variable) to eachother when there is nothing in front, you always assume the coefficient is 1. since there are 3 x's, (1)x+(1)x+(1)x=3x. hope this helps:)

It would be 0 because 0=3x and 3x=0 so the answer would be x=0

A-50
B-100
C-125

Answers

Answer:

I think it's D

Step-by-step explanation:

because if

50 = 25%

100 = 50%

200 = 100%

I think it’s D because if you reread the question it says what is the total number, and D is 200 rather than C (125), I don’t think this helps but it’s a choice
