A, C, and E. This is because dilations change the size/length of the sides = the sides cannot be congruent, however the angles are the same.

Answer with explanation:

Dilation of any geometrical shape means, producing an image , that has larger or smaller size than Pre image,

→Image > Pre-Image,≡If dilation factor > 1

→Image < PreImage,≡If 0<Dilation factor<1.

But , Image and Preimage are Similar in both the cases.

So,out of the five statement, the correct statements are:

1. Dilations produce images that are similar to the pre-image.

3. Dilations produce images that have angles that are congruent to the pre-image.

5. Dilations produce images that have sides that are proportional to the pre-image.

You want to put some money in a simple interest account it pays 8% interest annually for 2 years you would like to earn 500 doll

Semmy [17]

You deposit some money into a bank account paying 8% simple interest per year. You received $500 in interest after 2 years. How much the deposit (principal) was?

Result

The principal was $3125.

Explanation

Find principal by using the formula I=P⋅i⋅t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.

In this example I = $500, i = 8% and t = 2 years, so

IPPP=P⋅i⋅t=Ii⋅t=5000.08⋅2=3125

May someone please help me with this Math problem, Thank you

Semmy [17]

Answer:

c. 10

Step-by-step explanation:

Eliminate parentheses using the distributive property.

3(b+4) -2(2b+3) = -4 . . . . given

3b +12 -4b -6 = -4 . . . . . parentheses eliminated

-b +6 = -4 . . . . . . . . . . . . collect terms

-b = -10 . . . . . . . . . . . . . . subtract 6

b = 10 . . . . . . . . . . . . . . . . multiply by -1

_____

The rules of equality require that any operation you perform on one side of the equal sign must also be done on the other side. So when we say "subtract 6", we assume you know that means "subtract 6 from both sides of the equation", for example.

HELP!! Suppose the area of a circle is 201.0624 square feet. What's the diameter of the circle? (Use π = 3.1416.)

Liono4ka [1.6K]

<u>Answer</u>

C. 16 feet

<u>Explanation</u>

The area of a circle is given by the formula:

Area = πr² Where r is the radius of the circle and π = 3.1416

201.0624 = 3.1416 × r²

r² = 201.0624/3.1416

= 64

r = √64

= 8 feet

Diameter is twice the radius.

∴ diameter = 2r

= 2 × 8

= 16 feet
