Answers
Answer: It would be C(-3 -1) D(1 -1). (Aka the second one)
Step-by-step explanation:
The top of A and B is 4 units. If you count down five units vertically you get to -3, -1 and 1, -1. You need to count down 5 units because its asking you to get 20. So 5 x 4 = 20.

r = 0.85(43) because 100%-15% = 0.85.
b = 4(3) because you are buying 3 cans of tennis balls.
r = 36.55, b = 12
total cost = 8.5%(48.55) + 48.55

A bakery has three types of pie: apple, cherry, and peach. There are four times as many apple pies as peach pies. What is a possible percentage for each type of pie? Fill in the table and explain or show your work below. (Hint: There are multiple correct answers for this problem)
Answers
Answer:
The purpose of this task is to help students see the connection between a÷b and ab in a particular concrete example. The relationship between the division problem 3÷8 and the fraction 38 is actually very subtle.
3÷8 is the number you multiply 8 by to get 3.
38 is the number you get by taking 3 copies of the unit fraction 18.
So 3÷8 is defined in terms of multiplication, and 38 is defined in terms of unit fractions. It is not obvious that these two numbers are the same, so students need opportunities to see that they will necessarily always be the same. Note that if b people share a pies equally, then each person will get ab of a pie by the same kind of reasoning shown in the solution below.
This task is probably best suited for instruction or formative assessment.
Step-by-step explanation:
38 is the digit you gain by taking 3 copies of the division fraction 18. When the fraction 38 is extremely unpretentious.
What is a Fraction?
The objective of this task is to assist students to see the association between a÷b and ab in a special factual illustration.
The relationship between the division issue 3÷8 and the fraction 38 is very quiet.
3÷8 is the digit you reproduce 8 by to reach 3.
38 is the digit you get by assuming 3 copies of the unit fraction 18.
So 3÷8 is described in words of multiplication, and 38 is described in terms of unit fractions.
It is not pronounced that these two digits are the same, so students need possibilities to see that they will necessarily always be the same.
Note that: If b people share a pie equally, then each individual will get ab of a pie by the exact kind of logic shown in the resolution below.
Therefore, This task is probably best conformed for instruction or productive assessment.

What is 179,599 rounded to the nearest thousand?
Answers
Answer:
180,000
Step-by-step explanation:
Answer:
180,000
Step-by-step explanation:
the number closest to the 9,000 in 179,599 is five, therefore we have to round up. remember: if the closest number is 1,2,3,or 4, you keep the number and change the other place values behind to 0. example: round 230 to the closest hundred 230 ---> 200. If closest number is 5,6,7,8,or 9, round up. example: round 3576 to the closest ten 3576 ----> 3580. so try it with the original prompt: What is 179,599 rounded to the nearest thousand? 179,599 ---> 180,000
