How you find 8 and 10

Mathematics
1 answer:
Fittoniya [83]3 years ago
8 0

Answer:

8. X = 10.5 and 19. X = 5

Step-by-step explanation:

8. You know that a triangle interior angles should add up to 180° so:

(10x - 11) + (3x - 2) + (3x + 1) = 180

180 = 16x - 12

168 = 16x

The you divide each side by 16:

168 ÷ 16 = 16x ÷ 16

X = 10.5

10. You know that a straight line equals 180° and interior angles add up to 180° so:

1st you do 180 - 151 = 29°

2nd (11x - 1) + (20x - 3) + (29) = 180

180 = 31x + 25

155 = 31x

The you divide each side by 31:

155 ÷ 31 = 31x ÷ 31

X = 5

9966 [12]

Answer:

6 foot

Step-by-step explanation:

Since the board is 12foot and the angle makes 60 degrees to the wall, we can assume that it is the 30,60,90 degreees. 30,60,90 degrees triangle makes the side of x, 2x ,and xroot3.

Hence, the board(12foot) is equal to 2x.

x=6

Henry is up for retirement after 35 long years at his pharmacy. Before retiring, he would like to know how much he would receive
satela [25.4K]

To find how much Henry can expect to receive from Social Security on a monthly basis, we first need to find how much he cant expect to receive from social security per year.

We know form our problem that Henry averaged an annual salary of $45,620, so to find how much can Henry expect to receive from Social Security per year, we just need to find the 42% of $45,620.

To find the 42% of $45,620, we are going to convert 42% to a decimal by dividing it by 100%, and then we are going to multiply the resulting decimal by $45,620:

\frac{42}{100} =0.42

Social security annual payment = (0.42)($45,620) = $19,160.40

Since there are 12 month in a year, we just need to divided the social security annual payment by 12 to find how much he can expect to receive each month.

Social security monthly payment = \frac{19,160.40}{12} = $1.596.70

We can conclude that Henry can expect to receive $1.596.70 monthly from Social Security.

Simplify<br> a)<br> a^5 divided by a^3
Ymorist [56]

The value simplified is <u>a²</u>

-

In a power division with equal bases - we subtract the exponents and keep the bases.

  • The representation of this expression in formula is given by:

\large \sf a {}^{n}  \div a {}^{m}  =  \boxed{ \large \sf a {}^{n - m} } \\  \\

<h3>Resolution </h3>

\large \sf a {}^{n}  \div a {}^{m}  =  \boxed{ \large \sf a {}^{n - m} }

\large \sf a {}^{5}  \div a {}^{3}  =   \purple{\boxed{ \large \sf a {}^{2} } } \\

So, the answer of this expression is <u>a²</u>
