Answer: $7.72

Step-by-step explanation:

A easy way to this is by breaking each set of coins into values of 100 which we know is a dollar.

so  342 pennies can be divided into 100 3 times with the remainder of 42 cents so that $3.42

with nickels because they are worth 5 cents we have to see what times 5 = 100 which is 20. 62 goes into 20 3 times with the remainder of 2 and 2*5=10

so $3.10

dimes are worth 10 cents each so what times 10=100? 10 so 12 goes into 10 1 time with the remainder of 2 2*10=20 so $1.20

Then we add all the money $1.20+3.10+3.42=$7.72

Determine which ordered pairs are solutions to the equation 3x+7y=21
mafiozo [28]

Answer:

(0,3) and (7,0) are solutions.

Step-by-step explanation:

In a pair of coordinates, they are always listed as (x,y). Since this is the case, you plug in each coordinate to their respective places.

For (0,3)

3(0) + 7(3) = 21

0 + 21 = 21

For (7,0)

3(7) + 7(0) = 21

21 + 0 = 21

To double check that (1,2) isn't a solution:

3(1) + 7(2) = 21

3 + 14 = 21

17 = 21 X

This doesn't work.

Marking as Brainliest is much appreciated.

Show how to solve the problem 378 x 6 using place value with regrouping. Explain how you knew when to regroup.
KIM [24]

<u>Answer</u>

2,268


<u>Explanation</u>

<u> </u>

<u>By grouping 378 ca</u>n be written as,

378 = 300 + 70 + 8

6× 378 = 6 × (300 + 70 + 8)

             = (6×300) + (6×70) + (6×8)

             = 1800 +  420 + 48

              = 2,268

Don put $4,000 in a savings account with an interest rate of 4% for three years. If the interest is compounded annually, how muc
miskamm [114]

Answer:

$4,499.46

Step-by-step explanation:

We can use the compound interest formula for this problem:

A=P(1+\frac{r}{n} )^{nt}

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, lets change 4% into a decimal:

4% -> \frac{4}{100} -> 0.04

Now lets plug the values into the equation as shown below:

A=4,000(1+\frac{0.04}{1})^{1(3)}

A=4,499.46

Don will have $4,499.46 at the end of the three years.
