Answer:

A: 12k+30-20

B: $160

Step-by-step explanation:

A: You multiply all of the numbers that are in the parenthesis for distributive property (6x2k and 6x5) but you leave the numbers that are not inside the parenthesis (-20).

B: Once you get your equation from Part A, you just need to substitute k with $12.50.

12k+30-20

=12(12.50)+30-20

=150+30-20

=180-20

=160

How much to the nearest dollar should you deposit in a savings account at 2.5% annual simple interest in order to have a balance

Aneli [31]

Answer:

The amount we have to deposit in a savings account x = $ 17777.78

Step-by-step explanation:

Amount = $ 20000

R = 2.5 %

Time = 5 years

Take principal amount = x

Simple interest earned in five years

S.I. = $\frac{P R T}{100}$

$S.I. = \frac{P (2.5)(5)}{100}$

$S.I. = \frac{x}{8}$ ------- (1)

We know hat total amount is given by

Total amount = principal amount + simple interest

A = x + S.I.

$A = x + \frac{x}{8}$

$A = \frac{9x}{8}$

Given that the total amount after 5 years is = $ 20000

$\frac{9x}{8} = 20000$

x = $ 17777.78

This is the amount we have to deposit in a savings account.

➷ As they are similar triangles, there will be a scale factor between them. You may be given one pair of values on the triangle. Divide the larger value by the smaller value in order to find the scale factor between the triangles. For example, if the larger triangle has a length of 6cm and the smaller triangle has a length of 3cm, the scale factor would be 2. You would then multiply the given side by the scale factor to get the length.

A rectangle has a perimeter of 200m. The length to width ratio is 3:2. Find the LENGTH

Lapatulllka [165]

Answer:

length = 60m

Step-by-step explanation:

let '3x' = length

let '2x' = width

3x + 3x + 2x + 2x = 200

10x = 200

x = 20

length = 3x = 3(20) = 60
