a^2+b^2=c^2
20^2+15^2=c^2
400+225=c^2
625=c^2
**square root both sides**
c=25

Find the principal of interest!! ILL GIVE BRAINLIEST ! random answers will be reported
Artyom0805 [142]

Answer:

4)P = $615.38.   5)P = $1,482.35

Step-by-step explanation:

<u>4)P = $615.38</u>

Equation:

P = A / (1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year.

Solving our equation:

P = 640 / ( 1 + (0.04 × 1)) = 615.38461538462

P = $615.38

The principal investment required to get a total amount, principal plus interest, of $640.00 from simple interest at a rate of 4% per year for 1 years is $615.38.

<u>2)P = $1,482.35</u>

Equation:

P = A / (1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 12%/100 = 0.12 per year.

Solving our equation:

P = 2016 / ( 1 + (0.12 × 3)) = 1482.3529411765

P = $1,482.35

The principal investment required to get a total amount, principal plus interest, of $2,016.00 from simple interest at a rate of 12% per year for 3 years is $1,482.35.

A "child has six blocks, three of which are red and three of which are green". How many patterns can shemake by placing them all
makvit [3.9K]

Answer: There are 20 ways and 1680 ways respectively.

Step-by-step explanation:

Since we have given that

Total number of blocks = 6

Number of red blocks = 3

Number of green blocks = 3

So, Number of patterns she can make by placing them all in a line is given by

\dfrac{6!}{3!\times 3!}\\\\=20

If there are 3 white blocks

so, total number of white blocks becomes 9

So, Number of total pattern she can make by placing all nine blocks in a line is given by

\dfrac{9!}{3!\times 3!\times 3!}\\\\=1680\ ways

Hence, there are 20 ways and 1680 ways respectively.
