explanation:

Negative number raised to an even power is positive

For example let's look at (-7)6 , where (-7) , a negative number, is raised to 6 , an even exponent :

(-7)6 can be written as (-7)•(-7)•(-7)•(-7)•(-7)•(-7)

Now, using the rule that says minus times minus is plus, (-7)6 can be written as (49)•(49)•(49) which in turn can be written as (7)•(7)•(7)•(7)•(7)•(7) or 76 which is positive.

We proved that (-7)6 is equal to (7)6 which is a positive number

Using the same arguments as above, replacing (-7) by any negative number, and replacing the exponent 6 by any even exponent, we proved which had to be proved

One out of every 9 light bulbs is defective.
What constant of proportionality relates defective bulbs to total bulbs?

Answers

The answer is very simple you can simply put it as 0.1

The constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.

What is Constant Proportionality?

The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality.

Given:

One out of every 9 light bulbs is defective.

Total bulbs = 9

So, Defective bulbs = 1

Thus, Constant of proportionality = Defective bulbs / Total bulbs.

Constant of proportionality = 1 / 9

Hence, the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.

j) 32

f) -10

Step-by-step explanation:

b) x -7 = 4 + 10

x = 14 + 7

x = 21

d) 70 = 7m

70 ÷ 7 = 70m ÷ 70

10 = m

f) 12 - c = 8

12 - 8 = c

4 = c

h) 2y + 3y = 4 - 6 - 13

5y ÷ 5 = -15 ÷ 5

y = -3

Step-by-step explanation:ok so this easy enough just take a deep breath

b. x -7 = 4 + 10

= x = 4+10+7 => 21

d. 70 = 7m

=> m = 70/7. =>M= 10

f. 12 – c = 8

=> c = 12-8 => c=4

h. 2y + 3y = 4 – 6 – 13

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?

2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18

4.5 L of orange juice is needed to add to 18 L of pineapple juice to make the fruit juice recipe with the ratio of 2 parts orange juice to 8 parts pineapple juice. The correct option is B.

What is an expression?

An expression is a grouping of one or more mathematical or logical operators, operands (values, variables, or other expressions), and brackets in mathematics and computer programming that denote a computation that can be evaluated to generate a value.

The correct proportion that can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion is based on the ratio of 2 parts orange juice to 8 parts pineapple juice in the recipe. We can use this proportion to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice by cross-multiplying:

2/8 = j/18

2 × 18 = 8 × j

36 = 8j

j = 4.5

Therefore, 4.5 L of orange juice is needed to add to 18 L of pineapple juice to make the fruit juice recipe with the ratio of 2 parts orange juice to 8 parts pineapple juice.

Marcus has a 48-ounce soda. He drinks 15 ounces. What is the percentage of ounces Marcus has left from his soda? Round your answer to the nearest tenth.
A) 68.8
B) 45.6
C) 86.8
D) 34.9

Answers

Answer: A) 68.8%

Step-by-step explanation:

48-15=33

He has 33 oz of soda left. Divide 33/48 and then multiply by 100 to get a percentage. you get 68.75% but you have to round up the the nearest tenth so it will be 68.8%

answer:A

48-15=33

therefore he has 33 ounces left. so to work out the percentage you do the amount left divided by the total x100

33/48 x100 = 68.75

Because the answer wants the result rounded it will round up the the nearest 10th the be 68.8 which is A

The sum of all interior angles inside an "n" number of sides polygon is 180(n - 2) thus the measure of g will be 33 so option (A) is correct.

What is an angle?

The angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

The sum of all interior angles inside an "n" number of sides polygon is 180(n - 2).

Given that a polygon with a number of sides is 24.

And the measure of one angle is 5g.

Sum of all angles = 24(5g).

24(5g) = 180(n - 2)

120g = 180(24 - 2)

g = (18/12)(22)

g = 33

Hence "The sum of all interior angles inside an "n" number of sides polygon is 180(n - 2) thus the measure of g will be 33".
