Find the length of wire required to fence a circular park of diameter 280 m with 3 rounds..​

Answers

Answer 1

I'm guessing 3 rounds means 3 times around?

diameter = 280

circumference = dπ = 280π

280π x 3 = 840π

If you want it rounded it's about 2638.94 :)

Answer:

Step-by-step explanation:

Imagine you measure the length of 15 cars, and then sum that length, in order to see how big a parking lot must be. You do this in two different ways. First, you use the same bad tape measure for each car so that your measurement is always 1 cm too long, or always too short, for all of the measurements. For your second attempt, you use a different bad tape measure for each car, so there is an uncertainty of plus or minus 1cm in each measurement. What is your estimate of the total error in the sum of all the car lengths in these two cases

Answers

Answer:

± 15 cm  

Step-by-step explanation:

In the first case, since the measurement is 1 cm too long or too short, the error is ± 1 cm.

In the second case, the uncertainty or error is also ± 1 cm.

Now, since there are 15 cars, and there is an error of ± 1 cm in each measurement, by the error formula the total error in the sum of both cases is 15 × ±1 cm = ± 15 cm  

So, the total error in both cases is ± 15 cm.

Answers

x+1+1+x+x+1+x+1

The answer is c.

The expressions are equivalent to the perimeter of the shape is c. 4x + 4

What is perimeter?

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.

Perimeter of the rectangle = 2(length+width)

Given the paramters are;

length  = x + 1

W = x + 1

Perimeter of the shape= x+1+1+x+x+1+x+1

Perimeter = x+1+1+x+x+1+x+1

= 4x + 4

This is the expression equivalent to the perimeter of the shape

The answer is c.

8 1/5-2 7/8 fractions

Answers

i removed my answer because it was wrong look at the other peoples answers

Answer: 213/40 or 5.325

Step-by-step explanation:

We can find common denominators for 8 1/5 and 2 7/8.

The Lowest Common Denominator for 8 1/5 and 2 7/8 is 40.

8 1/5 = 41/5 = 328/40.

2 7/8 = 23/8 = 115/40.

Now we can subtract.

328/40 - 115/40 = 213/40.

Therefore, the answer is 213/40 or 5 13/40.

For this exponential function what is the output value (y) when the input value (x) is 3?

Answers

Substitute.

y = 5 • 2^3

= 5 • 8

y = 40

The value of the function y = 5(2)^(x) at x = 3 is (3, 40).

What is an exponential function?

An exponential function is in which the power to a constant value is independent.

Given, y = 5(2)^(x).

Now at x = 3 we'll replace the value of x with 3, therefore

y₃ = 5(2)^(3).

y₃ = 5×8.

y₃  = 40.

A pair of shoes that originally sold at $30 is now being offered at a 25% discount.

Answers

Answer:

$22.5

Step-by-step explanation:

You will pay $22.5 for a item with original price of $30 when discounted 25%.

Answer:

Refer to explanation

Step-by-step explanation:

The screenshot you put is the correct answer, here's another method to get the same answer:

Find what 25% is.

100% = 30

1% = 30 ÷ 100 = 0.30

25% = 0.30 x 25 = 7.50

Find the price after the 25% discount.

100 - 25 = 75

75% = 30 - 7.50 = 22.50 or 0.30 x 75 = 22.50 (Both solutions give the same answer)

A pail holds 6.3 liters of water. A bottle holds 3.5 liter less that water than the pail what is the volume of water in the bottle?​

Answers

The correct answer is 2.8 liters

Explanation:

The volume of the water in the bottle can be calculated by subtracting 3.5 liters from the volume of water the pail can hold (6.3 liters) because the volume in the bottle is 3.5 liters less than the one in the pail. Below, you can find the process.

volume in the pail - 3.5 liters = volume in the bottle

6.3 liters - 3.5 liters = 2.8 liters

This means the volume of water in the bottle is 2.8 liters. Also, you can double-check this answer by adding the volume in the bottle and the 3.5 liters (2.8 + 3.5 = 6.3).

A man could arrive on time for an appointment if he drove a car 40mph; however, since he left the house 15 minutes late, he drove the car 50 mph and arrive 3 min early how far from his house was his appointment

Answers

Answer:

60 miles

Step-by-step explanation:

Let us assume the distance between his home and place of appointment be x and t would be time taken at 40 mph

As we know that

Distance = speed × time

So,

x = 40t ............(1)

As he left the house 15 minutes late and also drove his car at 50 mph and arrive 3 minutes early

So,

15 minutes = 15 ÷ 60 = 0.25 hour

3 minutes = 3 ÷ 60 = 0.05 hour

Now the actual time taken is

= t - 0.25 - 0.05

=  t - 0.30

x = 50(t - 0.30)

x = 50t - 15.............(2)

Now

40t = 50t - 15

10t = 26

t = 3 ÷ 2 hour

Now

x = 40 × 3 ÷ 2

= 60 miles

Find the value of x and y

Answers

Answer: D. x=9√3; y=18

Step-by-step explanation:

This is a 30-60-90 special triangle, where we can use the rules to find the value of x and y. (For specific explanation, please look at the attachment below)

-----------------------------------------------------------------------------------------------------

X value

- The shortest side of the triangle that corresponds with [x] is 9 units. This is because it is half of the larger triangle's side length.

- Using the rules, the shortest side is x, then the second short side is x√3

- Substitute value in= x√3=(9)√3=9√3

Y value

- The shortest side of the triangle that corresponds with [x] is 9 units. This is because it is half of the larger triangle's side length.

- Using the rules, the shortest side is x, then the longest side is 2x

- Substitute value in= 2x=2(9)=18

What is the relationship between the volume of the rectangular prism and the rectangular pyramid?


(A) The volume of a rectangular pyramid is 2 times the volume of a rectangular prism. The volume of the rectangular pyramid is 396 cm3.

(B) The volume of a rectangular pyramid is 13 the volume of a rectangular prism. The volume of the rectangular pyramid is 66 cm3.

(C) The volume of a rectangular pyramid is 3 times the volume of a rectangular prism. The volume of the rectangular pyramid is 594 cm3.

(D) The volume of a rectangular pyramid is 12 the volume of a rectangular prism. The volume of the rectangular pyramid is 99 cm3.

Answers

Answer:

(B) The volume of a rectangular pyramid is 1/3 the volume of a rectangular prism. The volume of the rectangular pyramid is 66 cm3.

Step-by-step explanation:

Volume of a rectangular prism:

The volume of a rectangular prism is given by:

[tex]V_R = A_{b}*h[/tex]

In which [tex]A_b[/tex] is the base area and h is the height.

Volume of a pyramid:

[tex]V_P = \frac{A_{b}*h}{3}[/tex]

Relation:

From this, given the same base and the same height, the volume of the pyramid will be a third of the rectangular prism.

A rectangular prism has a volume of 198 cm³

So the volume of the pyramid is 1/3 of this, that is, 198/3 = 66 cubic centimers.

The correct answer is given by option B.
