Challenge A large university accepts 40% of the students who apply. Of the students the university accepts, 35% actually enroll. If 20,000 students apply, how many actually enroll? students would actually enroll.
pls help I am so stuck on this.
Answer:
2800 students would actually enroll.
Step-by-step explanation:
Of the 20,000 students who apply to a university, 40% are accepted.
It means:
20,000 × 40% = 20,000 × 40/100 = 8000 students are accepted
Of these, 35% enroll.
8000 × 35% = 8000 × 35/100 = 2800 students enroll
Therefore, 2800 students would actually enroll.

It takes me 20 minutes to do my math assignment for the day. I have been lazy and I spend 2 hours and 20 minutes doing my work last night. How many assignments did I finish?
Answer:
Assignments finished = 7
Step-by-step explanation:
Given that:
Time taken for one assignment = 20 minutes
Time spent on working = 2 hours 20 minutes
2 hours = 120 minutes
Time spent on working = 120 + 20 = 140 minutes
Number of assignments = [tex]\frac{Total\ time\ spent}{Time\ on\ one\ assignment}[/tex]
Number of assignments = [tex]\frac{140}{20}[/tex]
Number of assignments = 7
Hence,
Assignments finished = 7
Answer:
You finished seven (7) assignments.
Step-by-step explanation:
1. First, you need to know how many minutes are in an hour. That is 60 minutes.
2. If you know that it takes 20 minutes for each assignment and you spend 2 hours and 20 minutes to do all the assignments, you need to get both times to the same unit, minutes.
3. 2 hours is equal to 120 minutes. Now we need to add the other extra 20 minutes, leaving a total of 140 minutes of homework assignments.
4. Now you need to divide 140 minutes by 20 minutes because that is how long one assignment takes. 140÷20=7.
5. In the end, you finished 7 assignments in 2 hours and 20 minutes.

Solve x and y 3x-4y=18,9x-2y=12
Answer:
3x-4y=18
1xy=18
xy=18 ans
Answer:
X=2/5
Y=-21/5
Step-by-step explanation:
solve your system by substitution.
3x−4y=18;9x−2y=12
Step: Solve3x−4y=18for x:
3x−4y=18
3x−4y+4y=18+4y(Add 4y to both sides)
3x=4y+18
3x/3=4y+18/3
(Divide both sides by 3)
x=4/3y+6
Step: Substitute 4/3y+6 for x in 9x −2y=12:
9(4/3y+6)−2y=12
10y+54=12(Simplify both sides of the equation)
10y+54+−54=12+−54(Add -54 to both sides)
10y=−42
10y/10=-42/10 . (Divide both sides by 10)
y=-21/5
Step: Substitute
21/5 fory in x= 4/3y+6
x= 4/3y (-21/5) +6
X=2/5 (Simplify both sides of the equation)
Answer:
X=2/5
Y=-21/5

General Formulas and Concepts:
Algebra I
Reading a Cartesian Graph Function NotationStep-by-step explanation:
f(3) is simply asking for the y-value when x = 3. According to the graph, when x = 3, y = -2.
Therefore, f(3) = -2
If Four goats and two sheep’s cost Rs.2500, while six goats and five sheep’s cost Rs.6000. Find
the cost of one goat and one sheep separately
Answer: Cost of one goat = Rs 62.50 and Cost of one sheep Rs 1125.
Step-by-step explanation:
Let x = Cost of one goat and y= Cost of one sheep.
As per given,
4x+2y= 2500 (i)
6x+5y= 6000 (ii)
Multiply (i) by 3 , we get
12x + 6y = 7500 (iii)
Multiply (ii) by 2 , we get
12 x + 10y = 12000 (iv)
Eliminate (iii) from (iv)
10y- 6y = 12000 - 7500
⇒ 4y = 4500
⇒ y = 1125
Put y =1125 in (i)
4x+2(1125)= 2500
⇒ 4x+2250= 2500
⇒ 4x =2500-2250
⇒ 4x =250
⇒ x= 62.50
Hence, Cost of one goat = Rs 62.50 and Cost of one sheep Rs 1125.
Reese, Greg, and Brad meet once a week for coffee. They each have their favorite café and, to be fair, they use randomization to choose
where they will meet. Each person has a colored marble: red (R) for Reese, green (G) for Greg, and blue (B) for Brad. Each week, all three
marbles are mixed well in a bag and a marble is selected. The favorite café of the person associated with the selected marble is chosen for
that week's meeting. Which of the following represents the sample space for choosing a café for the first two weeks?

Need help with a few geometry questions !?!?
Answer:
1. ACB, CDB and ADC are all similar to eachother.
2. 10
3. CD=8, AD=10.666667, AC=13.33333
4. X=2.4
5. X=√10
6. X=√15
Step-by-step explanation:
1. To prove triangles are similar, prove they share at least two angles.
Triangle ACB is similar to triangle CDB because they both share a 90° angle and ∠B.
Triangle ACB is similar to triangle ADC because they both share a 90° angle and ∠A.
Since ACB is similar to both CDB and ADC respectively, CDB is similar to ADC.
2. Use similar triangles to find AB
ACB is similar to CDB
AB/CB=CB/DB
AB/10=10/6
AB=100/6=16.666667
Geometric mean: √(16.66667*6)=10
3.
Find CD using Pythagorus:
10²=6²+CD²
CD²=100-36
CD=√64=8
Use similar triangle ratios to find AD:
CDB is similar to ADC.
CD/DB=AD/DC
8/6=AD/8
AD=8(8/6)=10.6666666667
Find AC using Pythagorus:
AC²=10.66666666667²+8²
AC=√177.7777777778
AC=13.333333333
4. √(40²+30²)=50
30/50=X/40
X=2.4
5. (√35)²=X²+5²
35=X²+25
X=√10
6. √((√10)²-(√6)²=√(10-6)=2
√6/2=X/√10
6/4=X²/10
X²=10(1.5)
X=√15

When multiplying a decimal by a power of 10, the product
Answer:
When a decimal number is multiplied by a power of ten, the product is found by moving the decimal point to the right that many places as the power of ten. For example, in 3.45 × 10 2, the product is obtained by moving the decimal point two places to the right, i.e., 3.452 × 10 2 = 345.2.

What is the percent change from 80 to 20? I’m confused
Answer:
75% decrease
Step-by-step explanation:
To calculate the percentage increase:
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
If your answer is a negative number, then this is a percentage decrease.
To calculate percentage decrease:
First: work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Then: divide the decrease by the original number and multiply the answer by 100.
% Decrease = Decrease ÷ Original Number × 100
If your answer is a negative number, then this is a percentage increase.
