Answer:

- 1 5/24 cm

Step-by-step explanation:

We'll have to get the fractions to a common denominator. the least common denominator for 3 and 80 is 240.

So - 1 1/3 = - 1 80/240 = 320/240

21/80 = 63/240

-11/80 = -33/240

-------------------------------------

-320/240 + 63/240 - 33/240 = -290/240 = - 1 50/240 = -1 5/24 cm

Kevin invested $8,000 for one year at a simple annual interest rate of 6 percent and invested $10,000 for one year at an annual
irinina [24]

Answer:

Total interest =$1296

Step-by-step explanation:

Kevin invested $8,000 for one year at a simple annual interest rate of 6 percent

Simple interest = \frac{Pnr}{100}

P=8000, n=1 year  and r=6

interest = \frac{8000(1)(6)}{100}

Interest = 480  dollars

compound \ interest =P(1+\frac{r}{n} )^{nt}-p

P= 10000, t=1, r=8%=0.08, n=2 for semiannually

compound \ interest =10000(1+\frac{0.08}{2} )^{2(1)}-10000

Interest = 10816- 10000=816

Total interest = 480+816=1296

The sum of two numbers is 52. One number is 3 times as large as the other number. Which is the larger number
creativ13 [48]

The two number are 39 and 13

<em><u>Solution:</u></em>

Let the two numbers be "a" and "b"

Let the larger number be "a" and the smaller number be "b"

<em><u>Given that, sum of two numbers is 52</u></em>

a + b = 52 ---------- eqn 1

<em><u>One number is 3 times as large as the other number</u></em>

Larger number = 3 times smaller number

a = 3b -------- eqn 2

<em><u>Let us solve eqn 1and eqn 2</u></em>

<em><u>Substitute eqn 2 in eqn 1</u></em>

3b + b = 52

4b = 52

b = 13

<em><u>Substitute b = 13 in eqn 2</u></em>

a = 3(13)

a = 39

Thus the two number are 39 and 13
