A gardener makes a new circular flower bed. The bed is ten feet in diameter. Calculate the circumference and the area of the circular flower bed

Answers

Answer:

C=78.5

Step-by-step explanation:

C=πr²

r=1/2 of diameter

π=3.14

C=π5²

C=78.5

The circumference and the area of the circular flower bed are 31.4 feet and 78.5 square feet respectively.

What is a circle?

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle).

It is given that:

A gardener makes a new circular flower bed. The bed is ten feet in diameter.

D = 10 feet

The radius r = D/2 = 10/2 = 5 feet

A = πr²

π = 3.14

A = π(5)²

A = 78.5 square feet

The circumference:

C = 2πr

C = 2(3.14)(5)

C = 31.4 feet

Thus, the circumference and the area of the circular flower bed are 31.4 feet and 78.5 square feet respectively.

nearest tenth ?

Answers

Answer:

39.1 megabytes

Step-by-step explanation:

Percentages are out of a hundred, so 15.7% is 15.7 out of 100, aka 15.7/100, which is 0.157.

Now, you just need to multiple this number by 249 megabytes to get 0.157 * 249 = 39.093 which rounds to 39.1

Susan spent a total of 45$ at the grocery store I’d this amount she spent $18 on fruit what percentage of the total did she spend on fruit

Answers

Answer:

40% of the total was spent on fruit

Step-by-step explanation:

100%=45    x=18

100/x = 45/18    Now take the inverse of both sides

x/100 = 18/45

This leads to 1800 = 45x

1800 divided by 45 is equal to 40

The total percentage spent on fruit was 40%

If you built a model of the Empire State Building that is proportional to the real building. The height of the Empire State Building is 1,250 feet. If the scale of your model is 1 inch = 50 feet how tall is your model?

Answers

Let’s see now, there are 600 inches in 50 feet.
12in = 1ft, 12in * 50 = 600.
Which means the model you’ll be making will be a 1:600 ratio model. If we find out how many inches are in 1,250 feet, and divide that number by 600, we will get our answer.
1,250 * 12 = 15,000.
So 1,250 feet equate to 15,000 inches. Now we must divide 15,000 by 600.
15,000 ÷ 600 = 25.
So your model will be 25 inches (or 2’1” [2 feet & 1 inch] tall).

A. 20 to 22
B. 25 to 27
C. 19 to 21
D. 21 to 23

Answers

Answer:

19 to 21

Step-by-step explanation:

Head table is for 6 attendants

158 to 174 - 6 attendants

152 to 168 people for round tables

each round table can sit 8 guests

so, 152/8  168/8

19 to 21

Answer:

D. 21 to 23

Step-by-step explanation:

1. First, you use the biggest number of guests just to be safe. Since there will be about 174 guests attending

2. you divide 174 by the number of seats a round table can hold. Since the number is 8, you 174/8 which is 21.75.

3. You round up to the biggest number of tables that has the number 21 in it.

4. Your answer is D. 21 to 23

A playground is rectangular with a length of 78 miles. If the area of the playground is 820 square miles, what is its width? Input your answer as a fraction.

Answers

Answer:

10.5, [tex]10\frac{1}{2}[/tex], or [tex]\frac{21}{2}[/tex]

Step-by-step explanation:

To solve, you can use a variable (x) to represent the width.

The equation for area is A=L×W

So the Area is 820 and the length is 78.

820= 78w

Isolate the variable to solve.

w=10.5128....

If you round, it will be 10.5

10.5 as a fraction is [tex]10\frac{1}{2}[/tex] or [tex]\frac{21}{2}[/tex]

A tin contains 425g baked beans in sauce. The tin itself weighs 60g. How much will a pack of 6 tins weigh in kilograms

Answers

Answer:

2.91 Kg

Step-by-step explanation:

Tin weighs 60g, it contains 425g of baked beans, add that together to get a full tin of baked beans

= 485.

Multiply by 6 to get the total amount in grams

= 2910g.

Turn that into Kg.

2.91 kg.

The weight of 6 tins will be 2.19 Kg,

What is Unitary Method?

The unitary technique involves first determining the value of a single unit,  followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Tin weighs 60g, it contains 425g of baked beans,

So, the total weight along with tin

= 425 + 60

= 485 g

Now, the weight of 6 tins

= 485 x 6

= 2190 g

= 2190/1000 Kg

= 2.19 Kg

Hence, the weight is 2.19 Kg.

A pyrotechnician plans for two fireworks to explode together at the same height in the air. They travel at speeds shown below. Firework B is launched 0.25 s before Firework A. How many seconds after Firework B launches will both fireworks​ explode?

Answers

Answer:

  3.25 seconds after B launches

Step-by-step explanation:

In the 0.25 seconds before A launches, B will have traveled ...

  distance = speed · time

  distance = (240 ft/s)(0.25 s) = 60 ft

The speed of A is 20 ft/s faster, so will close that 60 ft gap at the rate of 20 ft/s. It will take ...

  time = distance/speed

  time = 60 ft/(20 ft/s) = 3 s

The fireworks will be at the same height 3 seconds after A is launched. That is 3.25 seconds after B is launched.

_____

Additional comment

Their heights will be (3 s)(260 ft/s) = 780 ft = (3.25 s)(240 ft/s).
