Answer:

2.25

Step-by-step explanation:

-9/10÷ -6/15

Because it is division, the minus sign will cancel out each other, so we have

9/10÷6/15

To make it easier, we turn the division sign to multiplication and that will change 6/15 to 15/6.

9/10 X 15/6

0.9X2.5

=2.25

We may also leave it at division

9/10÷6/15

0.9÷0.4

=2.25

Which term is correct when simplifying √128? A.) 16 B.) 12 C.) 10 D.) 8√2

alina1380 [7]

When dealing with roots, we want to factor to see if it's possible

$128 = 2 \times 64$
$= 2 \times 2 \times 32$
$= 2 \times 2 \times 2 \times 16$
$= 2 \times 2 \times 2 \times 2 \times 8$
$= 2 \times 2 \times 2 \times 2 \times 2 \times 4$
$= 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2$

now since we're dealing with square roots, we circle every pair of numbers we see in the final factoring
so..
$= (2 \times 2) \times (2 \times 2) \times (2 \times 2) \times 2$

now for every circled pair, we take only 1 of the 2 circled and bring it outside
anything left uncircled stays inside the root
so..
$= 2 \times 2 \times 2 \times \sqrt{2}$

now simply multiply
$8 \sqrt{2}$

Blanche bought a 5-year cd for $7100 with an apr of 2.8%, compounded quarterly, but she wants to take all her money out 9 months

lesantik [10]

Answer:

The money she will end up earning in interest on the cd = $11,352.90

Step-by-step explanation:

The formula for getting the accumulated amount(compounded) is;

$A =P(1+\frac{r}{n})^n*t$

Where

A = Accumulated amount

P = principle (deposit)

r = interest rate and

n = no of times interest applied per time period.

The interest is compounded quarterly so in one year it will be 4 times

In 5 years

n = (5×4)-3 = 17 (as she will withdraw 3 month before the completion of five years)

A = $7100(1+\frac{2.8}{100} )$ ^17

= 7100( 1 + 0.028)^17

= 7100(1.028)^17

= 7100 * 1.599

= 11,352.90

Therefore the money she will end up earning in interest on the cd = $11,352.90
