The line y= -3 is a reflection of the line y=5. What is the equation for the line of reflection?

Answers

Answer 1
Answer:

Answer:

y = 1

Step-by-step explanation:

The line of reflection will be a parallel line midway between y = - 3 and y = 5

y = (-3+5)/(2) = (2)/(2) = 1

line of reflection is y = 1

Answer 2
Answer:

Answer:

y=1

Step-by-step explanation:

the line of reflection will be a parallel line midway between y=-3and y=5

y=-3+5/2

=2/2=1

Your test grades in math this semester are 96, 100, 72, and 85. Find your mean grade. This is mean median and mode. A) 90.75 B) 88.25 C) 86.50 D) 84.00

Answers

B. 88.25

To find mean, you need to add all numbers given, then divide by the amount of numbers you have, therefore:

96 + 100 + 72 + 85
353

353 / 4

88.25

Estimate 6.1 DIVIDED 8

Answers

Estimate 6.1 DIVIDED 8
When you say estimate, meaning you have to round off the decimal to its nearest whole number to solve it easily 
=> 6.1 = 6
=> 6  / 8 = 0.75 is the quotient of the given equation.
(6.1)/(8) ≈0.8

You round off to one decimal place.

The ratio of apples to bananas in a bowl of fruit is 2 to3. If there are 12 apples in the bowl, then how many
bananas are there?

Answers

We know that the ratio of apples to bananas is 2 to 3, which can also be written as 2/3.

Let's use a proportion to solve for the number of bananas:

2/3 = 12/x

Here, x represents the number of bananas in the bowl.

To solve for x, we can cross-multiply:

2x = 3 * 12

2x = 36

x = 18

Therefore, there are 18 bananas in the bowl.

Answer:

18 bananas

Step-by-step explanation:

for every 2 apples, there are 3 bananas.

So, if there are 12 apples then the original ratio of number of apples is being multiplied by 6

To prove this, 2 is the original ratio of apples and when 2 is multiplied by 6, you get 12 apples

To ensure the ratio of apples to bananas is the same, you multiply the original ratio of bananas by 3 as well. This leaves us with 18 bananas for every 12 apples (3*6 = 18)

To check if you are correct, you divide both the number of apples and the number of bananas by 6 and you get the original ratio, 2 to 3.

The ratio is essentially the same throughout except when you increase it by a constant ratio, it is no longer simplified but it is the same.

I tried explaining this the best I could and I really hope this made sense and helped!
