Step-by-step explanation:

$(2c + 8) + (6c - 6) = 90 \\ 8c + 2 = 90 \\ 8c = 88 \\ c = \frac{88}{8} = 11$

The figure will equal to 90 degrees.

So what you want to do is this:

1. Add them both, and equal

2. Add like terms,

and equal that

to 90 degrees.

3. Then minus 2

from both sides.

4. And you will 88 on the

right side, and 8c on the

left side.

5. Just divide from both sides.

2c+8+6c-6=90

8c+2=90

-2 -2

8c=88

/8 /8

c=11

Megan Spins the sinner 8 times. In those 8 spins, the arrow never lands on 3. Based on this information, should Megan be concern

o-na [289]

The chance to land on the number three is only a ¼ or 0.25 chance. Knowing that we can also understand the law of large numbers. The law of large numbers states that as the number of spins gets very large, eventually the experimental probability will reach the theoretical probability. Eight spins of the spinner is not a large number, so the probabilities will be different. In this case resulting in zero times landing on three. Therefore, Megan should not be concerned that the spinner is unfair.

If there are an estimated 20,000 barrels of unknown reserves of oil, annual consumption of oil is 800 barrels, and it is estimat

emmainna [20.7K]

Answer:

20, 000

Step-by-step explanation:

For a duration of 50 years, the consumption will be equal to the product of annual consumption and the number of years hence 800*50=40, 000 barrels.

Since 20, 000 barrels are unknown and they are part if consumption in the next 50 years, then the known or proven reserves will be given by getting the difference between total consumption and unknown reserve, expressed as 40, 000-20, 000=20, 000 barrels.

A coed little league team had 18 players . Even though it was raining half the girls and one third of the boys showed up for the

Genrish500 [490]

Answer:

The number of Girls players in the Team of 18 players is 6 .

Step-by-step explanation:

Given as :

The total number of player including boys and girls = 18

And $\frac{1}{2}$ times girls player + $\frac{1}{3}$ times boys player = 7

Let The number of boys player = B

The number of girls player = G

So, According to question

G + B = 18 ...1

$\frac{1}{2}$ × G + $\frac{1}{3}$ × B= 7

or, $\frac{G}{2}$ + $\frac{B}{3}$ = 7 ...2

or, Put the value of B from eq 1

or, $\frac{G}{2}$ + $\frac{18 - G}{3}$ = 7

Or, $\frac{G}{2}$ - $\frac{G}{3}$ + 6 = 7

or, $\frac{3G - 2G}{6}$ = 7 - 6

Or, $\frac{G}{6}$ = 1

∴ G = 1 × 6 = 6

Hence The number of Girls players in the Team of 18 players is 6 . Answer

Which table represents a linear function that has a slope of 5 and a y-intercept of 20? A 2-column table with 4 rows. Column 1 i

natali 33 [55]

Answer:

The 1st table represents a function

Step-by-step explanation:

* Lets explain how to solve the problem

- Function is a relation where each input has a single output

- The notation of the function is f(x) = y , where x is the input of the

function and y is the out put of the function

- The domain of the function is x and the range of the function is y

* Lets find which table represent a function

# First table:

x y

-3 -1

0 0

-2 -1

- In the first table

∵ -3 has only -1

∵ 0 has only 0

∵ -2 has only -1

∵ 8 has only 1

∵ Every x has a single y

∴ The table represents a function

∴ The 1st table represents a function

- In the second table

x y

-5 -5

0 0

-5 5

6 -6

∵ x = -5 has y = -5 and y = 5

∴ One x has two values of y

∴ The table doesn't represent a function

- In the third table

x y

-4 8

-2 2

-2 4

0 2

∵ x = -2 has y = 2 and y = 4

∴ One x has two values of y

∴ The table doesn't represent a function

- In the fourth table

x y

-4 2

3 5

-4 0

∵ x = -4 has y = 2 and y = 0

∴ One x has two values of y

∴ The table doesn't represent a function
