Answer:
769.50
Step-by-step explanation:
First find how much is one student
95/20=4.75
Then, 162 x 4.75=769.50
if we do 95/20 we get 4.25 that would be the cost for each student and all we have to do is multiply 162 by 4.25 and u get your answer of 688.5

What variable is known as the data that you are collecting?.
Answer:
Step-by-step explanation:
Quantitative variables
When you collect quantitative data, the numbers you record represent real amounts that can be added, subtracted, divided, etc. There are two types of quantitative variables: discrete and continuous.
In the figure shown, the measures of all angles are equal, and AB = EF.
There are two solid triangles, triangle ABC and triangle DEF.
What type of triangle is △ABC?
What type of triangle is △EFG?
Select all that apply.
A. △ABC: right; △EFG: right
B. △ABC: equilateral; △EFG: equilateral
C. △ABC: isosceles; △EFG: isosceles
D. △ABC: scalene; △EFG: scalene
E. none of the above
Answer:
B. △ABC: equilateral; △EFG: equilateral
C. △ABC: isosceles; △EFG: isosceles
Step-by-step explanation:
A triangle in which all angles are equal is an equilateral triangle. Any equilateral triangle is also an isosceles triangle (two sides/angles have the same measure).
The two triangles are both equilateral (B) and isosceles (C).
__
Additional comment
The angles of an equilateral triangle are all 60°. The sides are all the same length. A right triangle will have an angle of 90°, so the given triangles cannot be right triangles. A scalene triangle has all angles/sides different measures, so the given triangles cannot be scalene.
y plus 4 plus 3(y plus 2)
Answer:
5y+11
Step-by-step explanation:
y+3+4(y+2)
Use the distributive property to multiply 4 by y+2.
y+3+4y+8
Combine y and 4y to get 5y.
5y+3+8
Add 3 and 8 to get 11.

runben sees 14 wheels on a total of 6 bicycles and tricycles how many bicycles and tricycles are there
Answer:
B = 4
T = 2
Step-by-step explanation:
First, figure out the equation.
We know that bicycles have 2 wheels, that there are 3 on a tricycle, and there are a total of 14 wheels and a total of 6 bicycles and tricycles.
Let b stand for bicycles and t stand for tricycles:
14 = 2b + 3t
6 = b + t
We can figure out the amount of either by rearranging the second equation to isolate one variable. I will solve it in two ways
In the first way, I will solve for b
(-t) 6 = b + t (-t)
6 - t = b
Plug this into the first equation and solve for remaining variable
14 = 2(6 - t) +3t
14 = 12 - 2t + 3t
14 = 12 +t
-12 -12
2 = t
6 - 2 = b
b = 4
The second way was to solve for t first
(-b) 6 = b + t (-b)
6 - b = t
14 = 2b + 3(6 - b)
14 = 2b + 18 - 3b
(-18) 14 = 18 -b (-18)
-4/-1 = -b/-1
b = 4
6 - 4 = t
t = 2
It doesn't matter which way you go, they both give you the exact same answer.
Sooo, recap!
1) write equations
2) switch the easier of the two to isolate one variable
3) substitute to find other variable (x2)
4) Find answers! =D
Hope this helps!

One half of the number of roses julia planted in her garden is 2/5 the number of tulips she planted, what was the ratio of the number of tulips to roses in the garden
The ratio of the number of tulips to roses in Julia's garden is 5:4.
A ratio is a quantitative comparison between two or more quantities or values.
Let the number of roses Julia planted is denoted by 'R',
and the number of tulips she planted is denoted by 'T'.
According to the given information,
"One half of the number of roses Julia planted is 2/5 the number of tulips she planted."
So, the mathematical expression is
(1/2)R = (2/5)T
T = (5/2)(1/2)R
T = (5/4)R
As, the ratio of the number of tulips to roses is T:R, which can be expressed as (5/4):1 or simply 5:4.
Therefore, the ratio is 5:4.

A boy rides his bike at a speed of 28 miles per hour. How
many hours will it take him to complete a trip of 120 miles?
Round your answer to the nearest whole number.
hours
Answer:
About 4 hours.
Step-by-step explanation:
Let's set up a proportion and cross multiply.
[tex]\frac{28 miles}{1 hour} = \frac{120 miles}{x}[/tex]
Cross multiply.
120 = 28x
Divide by 28 on both sides.
= 4.28571428571
Round this to the nearest whole number, which is just 4. The answer is about 4 hours.
what is the greatest common factor of 48r^3s^5 and 64rs^4
Answer:
16rs⁴
Step-by-step explanation:
prime factorization of 48r³s⁵ is: 2·2·2·2·3·r·r·r·s·s·s·s·s
prime factorization of 64rs⁴ is: 2·2·2·2·2·2·r·s·s·s·s
if you were to circle factors common to each you would have:
2·2·2·2·r·s·s·s·s which equals 16rs⁴ which is the GCF

Answer:

Max percentage improvement in the first exam = [tex](\frac{6}{20}[/tex] ×[tex]100)[/tex] %
=[tex]\frac{600}{20}[/tex]%
= [tex]30[/tex]%
Maria percentage improvement in the first exam =[tex](\frac{30}{90}[/tex] ×[tex]100)[/tex]%

Hence, 30% < 33.33%
Therefore, Max showed less improvement.
I need help with this. Plspslpsss help me
Step-by-step explanation:
1. k = 32
k + 19 = 51
32 + 19 = 51
51 = 51
correct, so, k=32 is a valid solution.
2. x = 43
16 = x - 27
16 = 43 - 27
16 = 16
correct, so, x = 43 is a valid solution.
3. m = 9
28 - m = 17
28 - 9 = 17
19 = 17
wrong. so, m = 9 is NOT a valid solution.
4. y = 8
y + 19 = 27
8 + 19 = 27
27 = 27
correct, so, y = 8 is a valid solution.
5. p = 22
19 = p + 3
19 = 22 + 3
19 = 25
wrong. so, p = 22 is NOT a valid solution.
6. r = 11
4 + r = 15
4 + 11 = 15
15 = 15
correct, so, r = 11 is a valid solution.
7.
a - 8 = 9 adding 8 to both sides
a = 17
8.
v + 13 = 15 subtracting 13 from both sides
v = 2
9.
16 = n - 24 adding 24 to both sides
40 = n or n = 40, of course
10.
c - 9 = 16 adding 9 to both sides
c = 25
11.
11 + k = 18 subtracting 11 from both sides
k = 7
12.
15 = w - 7 adding 7 to both sides
22 = w or w = 22, of course
