If the speed limit is 80 kilometers per hour, and Elena’s mom was driving 75 miles per hour, was she speeding? By how much?
Answers
First you need to converted miles into km as she was driving with miles but our speed limit is km so to maintain the balance we have to convert the measurements into one unit
Speed limit was 80km
She was driving 75 miles
We know,
1 mile = 1.609 km
So 75 * 1.609 = 120.675 km
So speeding = (120.675 - 80)
= 40.675
Therefore, she was over 40 km speed limit

To solve this problem, all you have to do is isolate the term of c from one side of the equation.
c-12=-4First, add by 12 from both sides.

Your friend is correct.
When a figure is reflected, it is flipped. Since it is reflected on the x-axis, that is the direction it is flipped in. When flipped, the coordinate of the bottom left corner is (1, 1). When you move the figure over 5 units (which is what translating is), the coordinates are (-4, 1) which matches with the corner of the second given figure.

A convenience store supplies two types of protein bars. One protein bar has 320 calories in the 2-ounce size. How many calories are in the 3-ounce size of the bar?
Answers
Since one protein bar has 320 calories in a 2-ounce size, we can divide 320 by 2. When solving, we get 160. This means there are 160 calories in one protein bar.
We are trying to find how much calories are in the 3-ounce size, so we must multiply 160 by 3.
The final answer to your question is 480. There are 480 calories in the 3-ounce protein bar.

Theresa uses a unique box in the shape of a trapezoidal prism for her specialty candles. The area of the base of the box for the smaller candle is 125 cm2 and the box is 12 cm tall. The box used for the larger candle has a base whose area is 160% that of the smaller box, and it is 6 centimeters taller.
What percent of the volume of the smaller box is the volume of the larger box?
Answer:
Answers
Answer:
41.7%
Step-by-step explanation:
100%----125
10%------125/100 x 10
=12.5
160%-----12.5 x 16
=200
volume of small box = 200 x (12+6)
= 3600
volume of large box = 125 x 16
= 1500
percentage of volume of small box is the volume of large box
= 1500/3600 x 100%
=41.667% (5 s.f)
=41.7% (3s.f)
