Answer:

Using pythagorean therom √32 = c and b = 4

Step-by-step explanation:

a^2 + b^2 = c^2

Since a and b are the same just plug them in.

4^2 + 4 ^2 = c^2

16 + 16 = c^2

32 = c^2

√32 = c

Multiply. Answer as a fraction. Do not include spaces in your answer 5 1/6•(-2/5) =???

Ne4ueva [31]

Answer:

2 1/15

Step-by-step explanation:

Hey there!

Well to multiply,

5 1/6 • -2/5,

we need to make 5 1/6 improper

$\frac{31}{6} * -\frac{2}{5}$

31 * 2 = 62

6 * 5 = 30

$-\frac{62}{30}$

Simplified,

$\frac{31}{15} \\Proper\\2 \frac{1}{15}$

2 1/15

Hope this helps :)

What is the 32nd term of the arithmetic sequence where a1 = 14 and a13 = -58?

liq [111]

The nth term of an arithmetic sequence is found from:
$n_{th}\ term=a+(n-1)d$
Plugging in the given values, we get for the 13th term:
-58=14+12d
12d =-58 - 14 = -72
d = -6
So, the 32nd term is:
$a_{32}=14+(32-1)-6=-172$

A number increased by 4 is the same as 19 minus 2 times the number

ElenaW [278]

Hello from MrBillDoesMath!

Answer:

n = 5

Discussion:

Let the original number be "n" Translating the problem statement to mathematical symbolism:

n + 4 = 19 - 2n => add 2n to both sides

n + 2n + 4 = 19 - 2n + 2n => combine like terms

3n + 4 = 19 => subtract 4 from both sides

3n = 19 -4 = 15 => divide both sides by 3

n = 15/3 =5

Check: Does 5 +4 = 19 - 2(5)? Does 9 = 9? Yes. so the value for n is confirmed correct.

Thank you,

September 6 is a Read Book Day.Polina read 5 times as many pages as Marcus read.Together,the read 108 pages.How many pages did e

Gemiola [76]

Answer:

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18

Step-by-step explanation:

Let

x -----> number of pages that Polina read

y ----> number of pages that Marcus read

we know that

x+y=108 ----> equation A

x=5y -----> equation B

substitute equation B in equation A and solve for y

$5y+y=108\\6y=108\\y=18$

Find the value of x

$x=5y -----> x=5(18)=90$

therefore

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
