Answer:

Step-by-step explanation:

Draw a picture. Seriously, this time you need to, so you can see that PS is the hypotenuse of a right triangle with legs of length 3 and 4 .

PS = √(3² + 4²) = 5

Perimeter = PQ + QR + RS + PS = 9 + 4 + 6 + 5 = 24 cm

Need Help ASAP!!
Aleksandr-060686 [28]

Answer:

$1480.24

Step-by-step explanation:

This will be solved by the formula:

FV=I(1+r)^t

Where

FV is the future value (what we are looking for)

I is the initial amount (which is $1000)

r is the rate of interest per period (8% is annual interest, but the period is SEMI-ANNUAL, that's 6 months, half of yearly. So r would be half of 8%, which is 4% or r = 0.04)

t is the times compounding occurs in the whole time (The whole time period is 5 years, but compounding occurs semi-annually, so 5*2 = 10 times. Thus, t = 10)

<em>plugging the info into the formula we will get our answer.</em>

<em>FV=I(1+r)^t\\FV=1000(1+0.04)^{10}\\FV=1000(1.04)^{10}\\FV=1480.24</em>

The ratio of ebooks to novels is 4:5. if there are 32 ebooks how many novels are there?
12345 [234]
<h3>Answer:  40 novels</h3>

================================================

Work Shown:

n = number of novels

(32 ebooks)/(n novels) = 4/5

32/n = 4/5

32*5 = n*4 ............ cross multiply

160 = 4n

4n = 160

n = 160/4 .............. dividing both sides by 4

n = 40

There are 40 novels.
