Answer:

1 3/8.

Step-by-step explanation:

3 1/4 - 1 7/8

First convert to improper fractions:

3 1/4 = (3*4) + 1 / 4 = 13/4.

1 7/8 = (1 *8)+7 / 8 = 15/8. So we have:

13/4 - 15/8

The Lowest Common Multiple of 4 and 8 is 8 so we convert 13/4 to eighth's

13 / 4 = 13*2 / 4 *2 = 26/8

Finally: we have

26/8 - 15/8 = (26 - 15) /8

= 11 /8

= 1 3/8 (answer)

Fran deposited 4869 into a savings account that pays simple annual interest rate of 3.25% how much interest will she earn after

Whitepunk [10]

Answer:

$395.61

Step-by-step explanation:

The formula for simple interest is:

$i=Prt$

Where

i is the interest amount

P is the principal amount

r is the rate of interest per time period

t is the time period

Here,

P = 4869

we want to find after 30 months, that converted to years is:

30/12 = 2.5 years

t = 2.5

The annual rate is 3.25% = 0.0325

Now, substituting, we find our answer:

$i=Prt\\i=(4869)(0.0325)(2.5)\\i=395.61$

The interest earned is <u>$395.61</u>

Which shows the correct simplification of product of powers?

Brums [2.3K]

The power symbols are missing.

I can infere that the product intended to simplify is (7^8) * (7^-4)., because that permits you to use the rule of the product of powers with the same base.

That rule is that the product of two powers with the same base is the base raised to the sum of the powers is:

(A^m) * (A^n) = A^ (m+n)

=>(7^8) * (7^-4) = 7^ [8 + (- 4) ] = 7^ [8 - 4] = 7^4, which is the option 3 if the powers are placed correctly.
