Katie memorized 40 multiplication facts last week. This week she memorized 56 multiplication facts. What is her percent of increase for memorizing multiplication facts this week? o 22.4 % O 71.4 % O 40% O 140%
The percent of increase in Katie's memorization of multiplication facts this week is 40%. Option C
To calculate the percent of increase for Katie's memorization of multiplication facts this week, we need to find the difference between the number of facts she memorized last week and this week, and then express that difference as a percentage of the original value.
Number of multiplication facts memorized last week: 40
Number of multiplication facts memorized this week: 56
To find the difference in the number of facts, we subtract the number memorized last week from the number memorized this week:
56 - 40 = 16
The difference is 16.
To calculate the percent of increase, we divide the difference by the original value and multiply by 100:
(16 / 40) * 100 = 40
The percent of increase in Katie's memorization of multiplication facts this week is 40%.
Therefore, the correct answer is C) 40%.

What is the distance between 5,-6 and 5,6
Answer: 12
Step-by-step explanation:
I will assume those are coordinates.
The distance between 2 points is given by √ (x2 − x1)^2 + (y2 − y1)^2.
Replacing the values, we get √ (5 − 5)^2 + (6 − -6)^2 = √0+144 = 12

if x:y = 2:5, find the value of (x + y) : (2x-3y)
Answer:
(x + y) : (2x-3y) = - 7/11
Step-by-step explanation:
The ratio is denoting:
x = 2
y = 5
Substitute your values into the equation's variables (x and y). Then solve.
(x + y) : (2x-3y)
(2 + 5 ) : [2(2) - 3(5) }
7 : [4-15]
7: -11
ratios can be turned into fractions.
7: -11 is the same thing as - 7/11

8n - 7 = -5(-3n - 7)
Solve Multi-Step equation.
Please explain how you i can understand too!
Answer:
n=-6
Step-by-step explanation:
8n-7=-5(-3n-7)
Multiply -5 to -3n and -7
8n-7= 15n+35
Bring 8n to the other side by subracting it from 15n
-7=7n+35
Subtract 35 from both sides
-42=7n
Divide both sides by 7
n=-6

Hope it helps!
[tex]ANSWERED:\\GraceRosalia[/tex]
Answer:
The 3 tells you to move 3 spaces up and the 4 tells you to move 4 spaces to the right.
Step-by-step explanation:
All slope can be visualized as "rise over run" meaning the top number is how far you go up or down depending on whether it is positive or negative and run can be visualized as how far to the right you move or if it is negativ, how far to the left.
What is the midpoint of a line with endpoints (6,5) and (14,7), (Your answer
should be an ordered pair)
Answer:
Midpoint = (10,6)
Step-by-step explanation:
Using Coordinates: X(6,5) and Y(14,7)
Using the midpoint formula: M = (X1 +Y1)/2, (X2 + Y2)/2
Midpoint of XY = (6 + 14) / 2, (5 + 7) / 2
Midpoint of XY = (20) / 2, (12) / 2
Therefore the midpoint of XY is (10,6)

Step-by-step explanation:
The Hulk just flew into the Boston airport to visit some family, but due to car problems, they are
unable to pick him up. He only has $20 on him. He needs to call a cab that costs $1.75 initially and
$.65 per mile. How far will he be able to go? If his family lives 25 miles away, will the cab be able to
get him to his family?
Answer:
Yes, he will be able to afford 25 miles
Step-by-step explanation:
20.00 - 1.75 = 18.25
He will have $18.25 after the initial payment.
18.25 / 0.65 = 28~
He will be able to go 28 miles with the 18 dollars he has left.
