3/7 of the students in a school are in sixth grade. a) How many sixth graders are there if the school has 70 students? 7 b) How many sixth graders are there if the school has 28 students?
Answer:
a) 30 sixth-graders
b) 12 sixth-graders
Step-by-step explanation:
You can solve this problem by multiplying fractions. In order to solve a, you need to multiply 3/7 by 70 students to e t the number of sixth-graders because 3/7 of the population (in this case it's 70) are 6th graders:
70 × 3 ÷ 7 = 70 ÷ 7 × 3 = 30
So if the school has 70 students, 30 are 6th graders.
For part b, you multiply the student population (28) by the ratio 3/7 to find how many 6th grader there are:
28 × 3 ÷ 7 = 28 ÷ 7 × 3 = 12
So if the school has 28 students, 12 are 6th graders.
a) There are 30 sixth graders are there if the school has 70 students.
b) There are 12 sixth graders are there if the school has 28 students.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
3/7 of the students in a school are in sixth grade.
Now,
a) Let the students in school = 70
Then, Number of students in sixth grade = 3/7 × 70
= 3 × 10
= 30
b) And, Let the students in school = 28
Then, Number of students in sixth grade = 3/7 × 28
= 3 × 4
= 12
Thus, a) There are 30 sixth graders are there if the school has 70 students.
b) There are 12 sixth graders are there if the school has 28 students.

what is 0.000036÷180 in standard form
Answer: 36/1000000 is the pq form of the given no..
Step-by-step explanation:
The standard form of 0.000036÷180 is 2 × [tex]10^{-7}[/tex] .
How do you express a number in standard form?Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form. 1.23 × [tex]10^{8}[/tex]; If you observe carefully, 1.23 is a decimal number between 1.0 and 10.0 and so we have the standard form of 123,000,000 as 1.23 × [tex]10^{8}[/tex].
According to the question
0.000036÷180 in standard form
Now,
0.000036÷180
= [tex]\frac{0.000036}{180}[/tex]
= 0.0000002
= [tex]\frac{2}{10000000}[/tex]
= 2 × [tex]10^{-7}[/tex] is the standard form .
Hence, the standard form of 0.000036÷180 is 2 × [tex]10^{-7}[/tex] .

Joe and John have Repair shops. Joe charges $11.25 per hour for repairs. The table below show's John's rate: Who earns more money per hour? How much more money does that person charge per hour?
Answer: John earns $0.25 more an hour than Joe does.
Step-by-step explanation: 3 hours is equivalent to $34.50 in payouts, meaning in order to get the hourly charge you would have to divide 34.50 by 3. Which is 11.5 or 11.50. 11.25 is 0.25 below 11.50. Hope this helps! :)

Kaylee works at Claire's Jewelry Store at the mall. She earns $7.75 per hour. She earned $93.00 over the weekend. Her final check for the week was $232.50 (before deductions). How many hours did she work in addition to the weekend hours?
Answer:
18 hours during the week days
Step-by-step explanation:
weekend pay + week day pay = total pay
93 + week day pay = 232.50
Subtract 93 from each side
93-93 + week day pay = 232.50-93
week day pay = 139.50
She makes 7.75 per hour
139.50 = hours * pay rate
139.50 = hours*7.75
Divide each side by 7.75
139.50/7.75 = hours
18 = hours
