Bonnie has a rectangular photographic print that is 5 inches wide and 7 inches long. If she multiplies both the length and width by 1.5, how will the perimeter of the print increase?
a.) It will be 1.5 times the original size.
b.) It will be 1.75 times the original size. ******
c.) It will be 2.25 times the original size.
d.) It will be 12.0 times the original size.
What is the distance between (78, 2) and (78, 103) along the y-axis on a coordinate grid?
a.) 105
b.) 80 ******
c.) 78
d.) 101

NO NO NO !!!! a.) 1.5 !!!!
lengths including perimeter scale with length scale
AREA scales with square of length scale
second also wrong
along y it is difference in y
103 - 2 = 101 which is d.)
Oh OK, I understand now! Thanks So Much!
sorry that was my sister. her name is Cindy.
Thanks So Much!
thanks for the answer.
Thanks!
You are welcome :)
To determine how the perimeter of the rectangular photographic print will increase when both the length and width are multiplied by 1.5, we need to calculate the new dimensions of the print.
Given that the original width is 5 inches and the original length is 7 inches, we can calculate the new width by multiplying it by 1.5:
New width = 5 inches * 1.5 = 7.5 inches
Next, we calculate the new length by multiplying the original length by 1.5:
New length = 7 inches * 1.5 = 10.5 inches
To find the new perimeter, we add together the new width and new length, and then multiply by 2 because a rectangle has two pairs of equal-length sides:
New perimeter = (7.5 inches + 10.5 inches) * 2 = 36 inches
Comparing the new perimeter (36 inches) to the original perimeter (5 inches + 7 inches) * 2 = 24 inches, we can see that the new perimeter is 1.5 times the original size.
Therefore, the correct answer is option a.) It will be 1.5 times the original size.
Regarding the distance between (78, 2) and (78, 103) along the y-axis on a coordinate grid, we can calculate it by finding the difference between the y-coordinates of the two points.
Given that the y-coordinate of the first point is 2 and the second point is 103, we calculate the difference:
Distance = 103 - 2 = 101
Therefore, the correct answer is d.) 101.
