Answers

Answer 1

Answer:

The unit rate would be higher if Simon raised $30.00 for selling 10 candles.

What is rate ?

In math, a rate is a ratio that compares two different quantities which have different units.

Now given that,

Total candle sold = 10

Total amount of 10 candles = $25.00

Thus, amount per candle = $25/10

⇒ amount per candle = $2.5

Similarly, Total candle sold = 10

Total amount of 10 candles = $30.00

Thus, amount per candle = $30/10

⇒ amount per candle = $3

Now, since total of $30.00 for selling 10 candles is greater than total of $25.00 for selling 10 candles.

Thus, the unit rate would be higher.

Thus, the unit rate would be higher if Simon raised $30.00 for selling 10 candles.

Answer 2

Answer: higher: 25.00÷10=$2.50 and 30.00÷10=$3.00

so the unit rate is higher

Which of the following is a example of perpendicular lines

Answers

The correct option is D.

Important information:

Each graph has two lines.

Perpendicular lines:

Two lines are called perpendicular lines if the angle between those lines at the intersection point is 90 degrees.

In option A, the lines are parallel because they have the same direction and slope.

In option B, if we increase the lines, then they can not make a 90-degree angle.

In option C, the lines are not making a 90-degree angle.

In option D, the lines are perpendicular because they are making a 90-degree angle.

Therefore, the correct option is D.

Its option D. the first is parallel and the rest two will intersect at a point but not at 90 degree. Since, in the fourth one, the lines meet at 90 degree, it is a perpendicular line

Change each fraction or mixed number to a decimal.
3/8, 7/10, 2 9/30

Answers

each fraction is literally saying the top number diveded by the bottom number. SO...

3/8 = 3 divided by 8 = 0.375
7/10 = 7 divided by 10 = 0.7
2 9/30 = turn to imporper fraction = 69/30 = 69 divided by 30 = 2.3

Hope this helps!

3/8=0.375
7/10=0.7
2 9/30=69/30=2.3

How to find the decimal? Make sure the fraction is not mixed. If it is, turn it into an improper fraction. Then divide the numerator(top number) by the denominator(bottom number). n÷d= decimal
