When answering equations that contain abolute values do I answer with the absolute value symbols ?
for example |-44| + |-34| do I answer with |-78| or 78 or |78|

Answers

Answer 1

Answer:

78

Step-by-step explanation:

|-44| + |-34|

Using absolute values

|-44|  = 44

 |-34| = 34

|-44| + |-34| = 44+34 = 78

You will not use absolute value symbols in your answer

Answer 2
It would just be 78, because you already found the absolute values for the original two number.

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

Find the slope from the graph.

-1/2


-4/3


3/4


-3/4

Answers

Answer: 3/4

Step-by-step explanation:

To find the slope from the graph, we need to look at the rise and run of the line. The slope is the ratio of the vertical change (rise) to the horizontal change (run).

Let's analyze the given options:

-1/2: This means that for every 2 units the line moves horizontally, it moves down 1 unit vertically.

-4/3: This means that for every 3 units the line moves horizontally, it moves down 4 units vertically.

3/4: This means that for every 4 units the line moves horizontally, it moves up 3 units vertically.

-3/4: This means that for every 4 units the line moves horizontally, it moves down 3 units vertically.

So, from the given options, the slope is 3/4. This indicates that for every 4 units the line moves horizontally, it moves up 3 units vertically.

Remember, the slope of a line is a measure of how steep the line is. It tells us how much the line is rising or falling as we move along the x-axis.

Use the slope formula to solve this question:

The slope formula is as followed:

y₂ - y₁

x₂ - x₁

where (x₁, y₁) and (x₂, y₂) are two sets of coordinates

Pick the two points on the line:

(0, 5) (4, 2)

Now, plug them into the equation and solve:

y₂ - y₁

x₂ - x₁

[tex]\frac{2-5}{4-0}[/tex] = [tex]\frac{-3}{4}[/tex]

The slope of the line is -3/4

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
16 over 18 equals j over 100

Answers

Step-by-step explanation:

16 over 18 equals over 100

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.

Jorge says there are 198 inches in 5.5 yards. Is he correct. Explain your answer. Show your work.

Answers

Answer: yes, he is correct

Step-by-step explanation:

since there is 36 inches in 1 yard, we will multiply 5.5 by 36 to find out how many inches are in 5.5 yards. since 5.5 yardsx36 inches in one yard=198 inches, Jorge is correct.

Yes, he is correct, because if in one yard is 36 inches, and half a yard is 18 inches, if you multiply 36 by 5, you get 180. Then add the half yard of 18 to have 5.5 yards, or 198 inches. :)

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.

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

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".
