Answer:
2323
Step-by-step explanation:
Mental math means to find a way to do this problem in your head without using paper, pencil or a calculator.
The question says there are 23 classes and each class is to collect 101 items.
The equation would be 23 x 101.
To do this in your head real quick, make the numbers easier to multiply.
Make the 101 items 100. That means you are telling each class to collect 1 less item or 23 less items total.
You can do this in your head real quick. 23 classes collecting 100 items is 2300 items.
You had each class collect 100 items instead of 101. That mean you didn't collect 23 items. So if you add those back in, you will get
2323 items.
You have to find how many kids are in eighth grade so you would multiply 34x6 and get 204 then you decide that by 1/4 and you get 51
Answer:
∠K =24
∠L =66
Step-by-step explanation:
first you need to find X in order to solve.
since they are Complementary they add together to equal 90 degrees
so we can set them equal to 90
13x-1=90
13x=91
x=7
now we can plug them in!
---
∠K = 3(7)+3 = 24
∠L =10(7)-4=66
Answer:
Negative Correlation
Step-by-step explanation:
Since the points are approximately lined up in a linear line pointing toward the bottom right, the slope of the best fit line would be a negative value. So the scatter plot shows a negative correlation.
