The simple interest on $12 000 invested at 8% per annum is $6720. Calculate the number of years for which the sum was invested. *

Answers

Answer 1

Answer:

7 years

Step-by-step explanation:

Given :

The Simple Interest earned, I = $ 6720

Rate of interest, r = 8% per annum

Principal amount, P  = $12,000

We known that :

[tex]$I = \frac{P \times T \times r}{100}$[/tex]

Here t is the number of years of investment.

Therefore,

[tex]$t= \frac{I \times 100}{p \times r}$[/tex]

[tex]$t= \frac{6720 \times 100}{12000 \times 8}$[/tex]

t = 7

So, the sum was invested for 7 years.

What is the surface area of the cylinder?




226.08 cm²

678.24 cm²

1,356.48 cm²

452.16 cm²

Answers

Answer:

452.16

Step-by-step explanation:

i got it right on test

The surface area of the cylinder is,

⇒ TSA = 452.16 cm²

We have to given that;

Height of cylinder = 6 cm

And, Diameter of cylinder = 12 cm

Hence, We get;

⇒ Radius of cylinder = 12 / 2 = 6 cm

We know that;

The formula for the total surface area of a given cylinder whose radius is r and height is h is,

TSA = 2πr (h + r)

Hence, We get;

TSA = 2πr (h + r)

TSA = 2 × 3.14 × 6 (6 + 6)

TSA = 37.68 × 12

TSA = 452.16 cm²

Thus, The surface area of the cylinder is,

⇒ TSA = 452.16 cm²

its A, B, E AND MABEY C

Step-by-step explanation:

The statements that are true about rectangles are mentioned in options  [tex](A),(B),(C),(E)[/tex] .

What  are rectangles ?

Rectangles a shape with four sides and having internal angles of  [tex]90^0[/tex]. Two of the sides are longer than the other two. The opposite sides of the rectangle are equal in length.

Properties of Rectangle :

[tex](a)[/tex]  The opposite sides are  equal and parallel to each other.

[tex](b)[/tex]  The diagonals bisect each other but not at [tex]90^0[/tex].

[tex](c)[/tex]   Diagonals are equal in length.

[tex](d)[/tex]   The diagonals of rectangle are congruent.

[tex](e)[/tex]   The sum of interior angles is equal to [tex]360^0[/tex] .

[tex](f)[/tex]   Each interior angle is equal to [tex]90^0[/tex].

[tex](g)[/tex]   The angles of a rectangle are all congruent.

[tex](h)[/tex]    Opposite angles of a rectangle are congruent.

So, from the above mentioned properties we can assume that statements mentioned in options  [tex](A),(B),(C),(E)[/tex]  are true about rectangles.

Hence, we can say that the statements that are true about rectangles are mentioned in options  [tex](A),(B),(C),(E)[/tex] .

A charge of 100 elementary charges is equivalent to?

[tex] \sf{with \: explanation \: please}[/tex]
​

Answers

Answer: The charge is equal to 1.602*10^(-17) C

Step-by-step explanation:

The elementary charge (the smallest charge that exists) is the charge of one proton (or the magnitude of the charge of a single electron), and it is equal to:

c = 1.602*10^(-19) C.

Where C stands for coulombs,

Then a charge of 100 elementary charges is equal to 100 times the charge of a single electron, this is:

Charge = 100*( 1.602*10^(-19) C) = 1.602*10^(-17) C

A rectangle lengths 12m and 17m and is dilated using the dilation (x, y) -> ( 0.4 x, 0.4y). What is the perimeter of the dilated rectangle?

Answers

Answer:

Perimeter of the dilated rectangle = 23.2 m

Step-by-step explanation:

If a point is dilated by a scale factor = k

Coordinates of the image point after dilation will follow the rule,

(x, y) → (kx, ky)

From the given rule,

(x, y) → (0.4x, 0.4y)

Which reveals that the figure has been dilated by a scale factor = 0.4

Length of the rectangle = 12 m

Width of the rectangle = 17 m

If the given rectangle is dilated by a scale factor of 0.4,

Length of the image rectangle = 12 × 0.4 = 4.8 m

Width of the image rectangle = 17 × 0.4 = 6.8 m

Perimeter of a rectangle = 2(length + width)

Therefore, perimeter of the image rectangle = 2(4.8 + 6.8)

                                                                           = 23.2 m

A chef takes c cartons of eggs from the refrigerator. Each carton contains 12 eggs. The chef wants to have a total of at least 50 eggs.

Answers

Answer: 5 cartons

Step-by-step explanation:

If the Chef wants to have a total of at least 50 eggs and each carton contains 12 eggs, divide 50 by 12 to find out the number of cartons needed and then round the number up:

= 50 /12

= 4.16

Round it up to the nearest 1:

= 5 cartons

This will ensure that there is at least 50 eggs because 5 * 12 = 60 eggs.

They [the parents] begged their brother to care for the two little ones as he would his own.The uncle promised he would be a father to them, but he soon began to scheme to possess the money the parents had left in his care for the children. He sent for two robbers and bargained with them to take the two babes into the woods and kill them.After going many miles into the woods one of the robbers said, "Let us not kill the little children, they never harmed us." The other robber would not consent, so they came to blows. This frightened the children so much that they ran away and did not see the robbers again.They wandered on and on until they became so tired and hungry that at length they sat down at the foot of a tree and cried as if their hearts would break. The little birds heard them and began to trill sweet lullabies, which presently lulled them to rest.The birdies knew that the children would die of cold and hunger, so they covered them with leaves of crimson and brown and green. They then told the angels in Heaven the sad story of the lost babes, and one of the white-robed angels flew down to earth and carried both the little ones back to Heaven, so that when they awoke they were no longer tired and hungry, but were again with their dear mother.A.
