1. An account is opened with a balance of $2800earning 4.25% simple interest. What will be thebalance in the account in 30 years
JulijaS [17]

Answer:

$6370

Explanation:

The simple interest formula gives us the final amount A given the principal amount P:

A=P(1+rt)

where r is the interest rate and t is the time interval.

Now in our case we have

P = 2800

r = 4.25/100

t = 30 years

therefore, the above formula gives

A=2800(1+\frac{4.25}{100}\cdot30)

which simplifies to give

\boxed{A=\$6370}

Hence, the account balance after 30 years will be $6370.

Drag the simplified value into the box to match each expression.
Maru [420]

Answer:

The answers are as follows: 12 106 42

Step-by-step explanation:

Given: $ 18 - 4^2 + 5 \times 2 $  

Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate $ 18 - 4^2 $ separately and $ 5 \times 2 $ separately and add them. So we have $ 18 - 16 + 10 = 2 + 10 =12 $.

Now for the second question: $ 9^2 + 4 \times 7 - 3 $. we would get $ 81 + 28 - 3 = 106 $

Next, $ 5^2 - 4 + 7 \times 3 $. This could be written as:  $ 25 - 4 + 21 = 42 $. Hence the answers.

Becky has a board that is 2 and 3/4 feet long. She needs to cut the board into 11 pieces of equal length. How long should each p
zzz [600]

Answer:

1/4 feet long should each pieces be.

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity of 1 such as 3 miles per second or 4 km per hour

As per the statement: Becky has a board that is 2 and 3/4 feet long.

⇒ Length of a board = 2\frac{3}{4} =\frac{11}{4} feet

Also, she need to cut the board into 11 pieces.

by unit rate definition:

\text{Unit rate per pieces} = \frac{\frac{11}{4} }{11}

or

\text{Unit rate per pieces} = \frac{11}{4} \times \frac{1}{11} = \frac{1}{4}

Therefore, 1/4 feet long should each pieces be.
