Answer:

qqqqqqqqqq

Step-by-step explanation:

Answer:

In this question one has to look forward to the information's already given. Based on those given information's the answer to the question can be easily determined.

Principal amount = $4000

Time for which money is borrowed = 5 years

Rate of interest = 6%

Then

Amount of Interest = Principal * Rate * Time

                              = 4000 * 6% * 5

                              = 4000 * 6/100 * 5

                              = 40 * 30

                              = 1200 dollars

So the amount of interest that needs to be given is 1200 dollars. I hope the naswer and the procedure is clear enough for you to understand.

Answer:

Missing term = r²

Step-by-step explanation:

Given:

6r⁴ + 4r + ….  -2r⁴ + 3r = 4r⁴ + r² +7r

Find:

Missing term

Computation:

Assume missing term = A

So,

6r⁴ + 4r + ….  -2r⁴ + 3r = 4r⁴ + r² + 7r

6r⁴ + 4r + A -2r⁴ + 3r = 4r⁴ + r² + 7r

4r⁴ + 4r + A + 3r = 4r⁴ + r² + 7r

4r⁴ + 7r + A = 4r⁴ + r² +7r

A = r²

Missing term = r²

Answer:

75

Step-by-step explanation:

Step 1

Matt is ordering basketball jerseys For his country's league. Last year he ordered 512 jerseys. 64 those jerseys were orange.

The ratio of all Jerseys to Jerseys that are Orange =

512 : 64

8 : 1

Step 2

If he ordered 600 jerseys this year, how many of them will be Orange if the ratio of orange jerseys to all the jerseys remain the same?

Since we are maintaining the ratio in step 1

Let the number of orange jerseys = x

600 : x = 8 : 1

Hence

600/x = 8/1

Cross Multiply

8 × x = 600 × 1

8x = 600

x = 600/8

x = 75

Therefore, this year, the number of orange jerseys = 75

Answer:

zero

Step-by-step explanation:

Answer:

0 is a value of a for 7/a to make irrational number.

Answer:

height:6

if the base is a square that means all the side lengths are equivalent so it would be 8 for side lengths, and the volume is 128. plug it in with the formula to get 6

The height of a pyramid is 8cm

Supposing that:

The length of the sides of the square base the pyramid has = b units

The height of the considered square based pyramid = h units,

Then, its volume is given by: [tex]V = \dfrac{1}{3} \times b^2 \times h \: \rm unit^3[/tex]

Given;

The volume of pyramid= 128cm3

Length of side of square base= 8cm

Now,

128=1/3 x 8x8xh

128= 64/3 xh

h= 128x3/64

h=8

Therefore, the height with the volume 128cm3 will be 8cm

Answer:

The area of this figure is 22 meters squared

Step-by-step explanation:

Two shapes exist on this figure: a rectangle and a triangle. We must first find the area of the rectangle and add that area to the area of the triangle. So first, let's solve the rectangle.

As the area of a rectangle is length multiplied by width, we have 8 * 1 = area, or 8 meters squared. Now we save the value of 8 to add to the area of the triangle. So let's now figure out the area of the triangle.

As the area of a triangle is A = (HB)/(2), or that triangles height multiplied by its base, and dividing that whole number by 2, we can substitute numbers into this equation. This means we take 3.5, the height of the triangle, and multiply that number by 8, the base of the triangle, to get a value of 28. We then divide 28 by 2 to satisfy the equation A = (HB)/(2), and we get the value of 14.

Because of this, we add 8, the area of the rectangle, and 14, the value of the triangle to get a total value of 22. Now let's not forget to add meters squared as the unit of measurement as stated in the question.

This means that the total area of this figure is 22 meters squared.

The shape of the cross-section is a square

Step-by-step explanation:

Given

[tex]r =2[/tex]

[tex]h = 4[/tex]

See attachment

Required

The shape of the cross-section

From the attachment, we can see that when the cylinder is cut vertically, the shape formed is a quadrilateral of equal opposite sides.

The dimension of the shape is: the height of the cylinder and the diameter of the base circle

From the given parameters, we have the radius and the height to be:

[tex]r =2[/tex]

[tex]h = 4[/tex]

The diameter (d) is:

[tex]d = 2 * r[/tex]

[tex]d = 2 * 2[/tex]

[tex]d = 4[/tex]

So, the dimension is:

[tex]h = 4[/tex] and [tex]d = 4[/tex]

Since the height and the diameter have the same lengths, then the shape is a square.

V = 1/3 * pi r^2 h

V = 1/3 * pi * 5/2^2 * 6

V = 1/3 * pi * 25/4 *6

V = 2 * pi *25/4

V = 25/2 pi

C = 6.28

Answer:

6.28

Step-by-step explanation:

Its the formula 2πr. The diameter is 2 and the radius is half of 2 so 1. Just plug in 1 for r and multiply everything together.

n(k + m) = number of fruits

Step-by-step explanation:

n(k + m)

Remember that the fruits combined would be k + m.

Then to find the total, you would need to multiply by the number of plates, which is n. Therefore, you would get n(k+m) to showcase the total amount of fruits on the table.
