Answers

If the height of the cylinder is 3 feet and the base radius of the cylinder is 1 foot. Then the volume of the cylinder will be 9.43 cubic feet.

What is a cylinder?

A cylinder is a closed solid with two parallel circular bases and a curving surface connecting them.

A steel drum is shaped like a cylinder and it has a height of 3 feet and a base radius of one.

Then the volume of the cylinder will be

The volume of the cylinder is given as

Volume = πr²h

where r is the radius and h is the height of the cylinder.

We have

h = 3 ft

r = 1 ft

Then the volume of the cylinder will be

Volume = π x 1² x 3

Volume = π x 3

Volume = 9.4247

Volume ≅ 9.43 cubic ft

Then the volume of the cylinder will be 9.43 cubic feet.

calculate the volume of a cone whose base radius is 3 and half cm and vertical height 24cm​

Answers

The volume of a cone whose radius is 3 1 / 2 cm and vertical height is 24 cm is 307.72 cm³

Volume of a cone

The volume of a cone can be represented as follows:

volume = 1 / 3 πr²h

where

r = radiush = height

Therefore,

r  = 3 1 / 2 cm = 7 / 2 cm

h = 24 cm

Hence,

volume = 1 / 3 × π  × (7 / 2 )² × 24

volume of a cone = 1 / 3 × π × 49 / 4 × 24

volume of the cone = 1 / 3 × π × 1176 / 4

volume of the cone =  1176 / 12 π

volume of the cone = 98π

volume of the cone =  307.72 cm³

For garden A

Area

For garden B

2(50+B)=12050+B=60B=10

Area

50(10)500ft²

Surprisingly assumption at first turned right

Garden A has highest area not Garden B

Answer:

Garden A

Step-by-step explanation:

Formula

Perimeter of a rectangle = 2(w + l)Area of a rectangle = w × l

(where w is the width and l is the length)

Garden A

Given:

Perimeter  = 120 ftOne side length = 25 ft

Using the formula for the perimeter to calculate the missing side length:

Perimeter = 2(w + l)

⇒ 120 = 2(25 + l)

⇒ 120 = 50 + 2l

⇒ 2l = 70

⇒ l = 35 ft

Therefore, the dimensions of Garden A are:

width = 25 ftlength = 35ft

Area = w × l

⇒ Area of Garden A = 25 × 35

                                  = 875 ft²

Garden B

Given:

Perimeter  = 120 ftOne side length = 50 ft

Using the formula for the perimeter to calculate the missing side length:

Perimeter = 2(w + l)

⇒ 120 = 2(w + 50)

⇒ 120 = 2w + 100

⇒ 2w = 20

⇒ w = 10 ft

Therefore, the dimensions of Garden B are:

width = 10 ftlength = 50 ft

Area = w × l

⇒ Area of Garden B = 10 × 50

                                  = 500 ft²

Conclusion

As 875 > 500, Garden A has the largest area.

Scott and Huong each improved their yards by planting daylilies and ivy. They bought their
supplies from the same store. Scott spent $91 on 7 daylilies and 1 pot of ivy. Huong spent $105
on 7 daylilies and 3 pots of ivy. What is the cost of one daylily and the cost of one pot of ivy?

Answers

Answer:

daylilies - $12; ivy - $7

Step-by-step explanation:

one way to answer this question is by using two equations

first write your let statements

let d be daylilies and let i be ivy

7d + i = 91

7d + 3i = 105

then you can subtract the equations

you get -2i = -14

then divide eveything by -2

i = 7

ivy costs $7

lastly plug this into an equation

7d + 7 = 91

7d = 84

d = 12

daylilies cost $12

Calculate the portion of each mix that is peanuts, again expressing your answer as a percent. Which recipe has the greatest concentration of peanuts?

Answers

Answer:

Recipie A has a higher percentage of chocolate chips and Recipie B has a higher percentage of peanuts.

Step-by-step explanation:

Chocolate Chunks:

Recipie A calls for a total of ten cups. So 3 cups of chocolate chips are used in Recipe A. The percentage of chocolate chips in the mix is given by 3/10, which can be written as 30%. Recipie B now has a total of 20 cups. So in Recipe B 5/20, which can be written in percentages as 25%. Recipe C now has a total of 25 cups. So 6 cups of chocolate chips are used in the recipe. The percentage of chocolate chips in the mix is given by 6/25, which can be written as 24 percent. Recipie A has the highest percentage of chocolate chips of the three recipes.

Peanuts:

Recipie A calls for a total of ten cups. So, according to the recipe, A 2 cups are peanuts. The amount of peanuts in the mixture is given by 2/10, which can be written as a percentage of 20%. Recipie B calls for 20 cups. So there are 7 cups of peanuts in the recipe. The percentage of peanuts in the mix is given by 7/20, which can be written as 35%. Recipie C has a total of 25 cups, so there are 7 cups of peanuts in the recipe. The percentage of peanuts in the mix is given by 7/25, which is equivalent to 28 percent in percentages. The recipie b contains the highest percentage of peanuts of the three.

As a result, Recipie A has a higher percentage of chocolate chips and Recipie B has a higher percentage of peanuts.

The graph is a linear inequality, and the inequality that describes the graph is y < 2x - 1

How to determine the inequality?

From the graph, we have the following features:

y-intercept, b = -1It passes through the points (0,-1) and (1,1)The line is a dotted line and the lower region are shaded; so, we make use of the < inequality

Next, we calculate the slope using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{1 + 1}{1 - 0}[/tex]

m = 2

The inequality is then calculated using:

y < mx + b

This gives

y < 2x - 1
