i only need the awnser for questions 4 and 2 because i dont get them
Answer:
2) 20 students
4) 28 students
Question 2 is 25% - but it's asking how many. If you know the total number of students multiply that times .25 and that number is your answer. So .25 x 80 = 20
Question 4 is 35% also multiplied times the total number of students. So it would be the total number of students multiplied times .35.
So .35 x 80 = 28
Both of these questions want the number of students, not the percent.

The hypotenuse of a certain triangle is 5 units long and one leg is 3 units long
Did the area of the triangle
Answer:
6 units^2
Step-by-step explanation:
[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]3^{2} +b^{2} =5^{2}[/tex]
[tex]9+b^{2} =25[/tex]
[tex]b^{2}=16[/tex]
[tex]b=4[/tex]
Area of the triangle = Base * Height * 1/2 = 3 * 4 * 1/2 = 6 units^2

What is the volume of the composite figure if both the height and the diameter of the cylinder are 2.5 feet? Give the exact answer and approximate to two decimal places.
Answer:
16.36ft³
Step-by-step explanation:
First find the volume of the cylinder the add to the volume of the hemisphere.
I hope this helps.Its a trial btw feel free to delete if its not right lmmao
Answer:
16.36 ft3
Step-by-step explanation:
Volume of a Cylinder
V= π r2 h
π • 1.253 • 2.5 = 12.27ft3
Volume of a Hemisphere
2 • π • 1.253
2 • π • 1.95
12.26 /3 = 4.09 ft3
Both
4.09 ft3 + 12.27 ft3 = 16.36 ft3

Use graphs and tables to find the limit and identify any vertical asymptotes of the function.
limit of 1 divided by the quantity x minus 10 squared as x approaches 10
PLEASE ASNWER ASAP WITH WORK IN A TABLE PLEASE
Answer:
Step-by-step explanation: Given is a function as 1 divided by the quantity x minus 10 squared
Mathematically translating we get
the function
Since the function become undefined at x=10 we get
vertical asymptote is
x=10
Limit x tends to 10 of f(x) will exist since both limits are equal
This is because let x tends to 0 from left.
Then we have
f(x) =
Right limit also will be +infinity
This is because the curve is symmetrical about x=10 and hence limit would be +infinity.
3p + 10 = 2p + 21
a. 15
b. 17
c. 11
d. 21
Answer:
c. 11
Step-by-step explanation:
3p + 10 = 2p + 21
Subtract 2p from both sides.
3p - 2p + 10 = 2p - 2p + 21
Simplify.
p + 10 = 21
Subtract 10 from both sides.
p + 10 - 10 = 21 - 10
Simplify.
p = 11
Answer: c. 11
Answer:
c.11
Step-by-step explanation:
3+10=2+21
3+10−10=2+21−10
3=2+11
3−2=2+11−2p
=11

If a quadrilateral has these known angle degrees: 35, 35 and 145, what are the degrees of the fourth angle?
Answer:
145
Step-by-step explanation:
The total sum of all the angles is 360 degrees. If we add up 35, 35, and 145 we get 215. 360-215=145.
The residents of a certain dormitory have collected the following data: People who live in the dorm can be classified as either involved in a relationship or uninvolved. Among involved people, 15 percent experience a breakup of their relationship every month. Among uninvolved people, 30 percent enter into a relationship every month. What is the steady-state percentage of residents who are uninvolved?
Answer:
33.33%
Step-by-step explanation:
Given :
Breakup percentage = 15
New relationship percentage = 30
To obtain the steady state percentage of residents who are uninvolved, we could relate the scenario to the natural unemployment rate relation : seperation rate ÷ (seperation rate * finding rate)
Hence, we could use the Relation as this ;
Breakup percentage ÷ (Breakup percentage + new relationship rate)
15% ÷ (15% + 30%)
0.15 ÷ (0.15 + 0.30)
0.15 ÷ 0.45
= 0.33333
= 33.33%
If you were flipping a coin, and needed to get 2 heads in a row, what is the probability of getting two heads in a row. Use your probability tree to help. /
Answer:
1/4
Step-by-step explanation:
If you flip it twice the possible outcomes are
H H
H T
T H
T T
The chances of you getting H H is 1 / 4. If you flip it more than twice, the probability changes. Let's try three times. That gives you 8 different choices.
H H H *
H H T *
H T H
H T T
T H H *
T H T
T T H
T T T
What this gives is 3 chances out of 8 which is 0.375 and that's better than 0.25
Four would give you an even better result, There are 16 ways of flipping a coin 4 times. The successful results are
H H H H
H H H T
H H T T
H H T H
T H H T
T T H H
H T H H
I'm sure there might be a couple of more, but already you have done better than 3/8

Help me please I need the help
Answer:
Read below :)
Step-by-step explanation:
Take 75 / 15. Then in that many times, they will meet again. The answer is 75/15 = 5, so at 7:15 AM , they will meet again. Think of this like Chemistry. There is a restricting reactant and a non restrictive reactant. If you have 200 slices of bread, and 150 slices of cheese, the bread could only support 100 sandwiches. You'd have 50 slices of cheese left over. So the bread is the restrictive, or, in this case, 75, and the cheese is the non-restrictive number, or, 15. Hope this helps :)
