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.

A school band gives a year-end concert. It is held in a 400-seat auditorium. Each concert ticket sells for $10, and 85% of the tickets are sold. How much money does the band earn from the sale of the tickets?
Answer: $3,400
Step-by-step explanation:
There are 400 seats in the auditorium which means that there are 400 tickets to be sold.
85% of these tickets are sold. The number of tickets sold is:
= 85% * 400
= 340 tickets were sold.
Each ticket sells for a total of $10.
The amount of money made from ticket sales is therefore:
= No. of tickets sold * price of ticket
= 340 * 10
= $3,400

6m+27=8.25m
m=?
HELPPP
Answer:
12
Step-by-step explanation:
This is correct. Trust me.
I'm glad I could help:)
6m+27=8.25m
You have to subtract 6m on both sides first.
6m+27=8.25m
-6m -6m
27=2.25m
Now we divide 2.25 from both sides.
27=2.25m
/2.25 /2.25
12=m

1. Anthony threw a ball from the top of a 10-story building that was 165 feet
tall. The equation g(165 - h) = v2 can be used to find the maximum
height the ball can attain after being thrown from the top of the building,
Rewrite the equation to highlight the maximum height attained by the
ball, h.
Answer:
[tex]h = 165 - \frac{v^2}{g}[/tex]
Step-by-step explanation:
Given
[tex]g(165 - h) = v^2[/tex]
Required
Make h the subject
[tex]g(165 - h) = v^2[/tex]
Divide both sides by g
[tex]165 - h = \frac{v^2}{g}[/tex]
Subtract 165 from both sides
[tex]165 - 165 - h = \frac{v^2}{g} - 165[/tex]
[tex]- h = \frac{v^2}{g} - 165[/tex]
Multiply both sides by -1
[tex]-1 * - h = (\frac{v^2}{g} - 165)*-1[/tex]
[tex]h = 165 - \frac{v^2}{g}[/tex]

A ladder is leaning against
a brick building as shown in the figure. What
is the length of the ladder?
x ft
20 ft
15 ft
Answer:
25 ft
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
15^2 + 20 ^2 = x^2
225+400= x^2
625 = x^2
Take the square root of each side
sqrt(625) = sqrt(x^2)
25 = x
