The answer is 140.
If there are 140 hamburgers sold, and there were 2x as many cheeseburgers sold, that adds up to 420.
140 x 2 = 280 (Cheeseburgers)
So there were 280 cheeseburgers sold.
280 (Cheeseburgers) + 140 (Hamburgers) = 420 altogether.
Hope this helps!
Answer: the percent change in attendance from 2014 to 2015 is 11.54%
Step-by-step explanation:
In 2014, the total attendance at Jefferson school's Fall festival was 650.
In 2015, the attendance was 575. The change in the number of attendees between 2014 and 2015 is 650 - 575 = 75
There was a decrease in the number of attendees between 2014 and 2015.
The percent change in attendance from 2014 to 2015 would be attendance in 2015 divided by attendance in 2014 and multiplied by 100. It becomes
75/650 × 100 = 11.54%
Answer:
0.2
Step-by-step explanation:
Similar triangles are triangles which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. This means that if a rectangle has sides 3 by 4 its area will be 12. But its image after being dilated by 2 is 6 by 8 or twice the side. Will the area also be twice the size? The area of the image is 6*8 = 48. This is 4 times bigger than 12. Not twice as big. So the similarity of the area is the scale factor squared.
So if figure A has area 13 units. And they have a ratio or scale factor of 1/8 then the area sclae factor will be 1/8*1/8 = 1/64.
So 13*1/64 will be the area of figure B.
13* 1/64 = 13/64 = 0.2
D because of the distribution property
