Multiply the numerator and denominator of each term to get a common denominator of 30.

2/5= 12/30 (multiply by 6)
1/3= 10/30 (multiply by 10)
7/10= 21/30 (multiply by 3)

21+10+12= 43
43/30= 1 13/30

Final answer: 1 13/30

The school chorus has 52 students which represents 26% of the seventh graders. How many students are in the seventh grade
barxatty [35]

Answer:

There are 200 students in the seventh grade.

Step-by-step explanation:

For equations like these, you have to use the is/of formula, which is:

Percent/100 = is/of.

Since you are trying to find how many students are in the seventh grade, this means that 52 <u><em>is</em></u> 26% of the total amount of students in the seventh grade. So, the formula would look like so:

26/100 = 52/n.

Next, you have to cross multiply, which means you would multiply 26 by n, and 52 by 100.

Then, you are going to have this left over from the cross multiplying:

5200 = 26n.

Divide 26 on both sides, leaving you with:

1n = 200, or n = 200.

What is the shape of a
Delvig [45]

Answer:

B) Triangle.

Step-by-step explanation:

If you find a cross section <em>PARALLEL</em> to the base, it is the same shape as the base.

If you find a cross section <em>PERPENDICULAR</em> to the base, it is the same shape as the face.

In this case, the cross section will be the same shape as the pyramid's faces, which are triangles.

What is the surface area of the figure shown? (Use 3.14 for π.)
Ivanshal [37]
We know that
Part 1) 
[surface area of a cone without base]=<span>π*r*l
r=3 in
l=slant height ----> 6 in
</span>[surface area of a cone without base]=π*3*6------> 56.52 in²

[surface area of a cylinder]=π*r²+2*π*r*h------> only one base
r=3 in
h=5 in
[surface area of a cylinder]=π*r²+2*π*r*h
[surface area of a cylinder]=π*3²+2*π*3*5-----> 122.46 in²

[surface area of the composite figure]=56.52+122.46-----> 178.98 in²

the answer Part A) is
 178.98 in²

Part B) 
[surface area of the composite figure]
=12*16+2*12*7+2*16*7+5*12+5*16+13*16----> 932 ft²

the answer Part B) is 
 932 ft²
