In Jonesville Louisiana 125 students attend last Friday high school football game. This about 25% of the students currently enrolled at the school. How many students are enrolled at the high school?
Answers
Answer:
500 students
Step-by-step explanation:
In Jonesville Louisiana 125 students attend last Friday high school football game. This about 25% of the students currently enrolled at the school. How many students are enrolled at the high school?
Let the number of students enrolled at the high school be represented as x
Hence:
25% of x = 125
25/100 × x = 125
25x /100 = 125
Cross Multiply
25x = 125 × 100
x = 125× 100/25
x = 500 students

Lin runs 2 3/4 miles in 2/5 of an hour. Tlyer runs 8 2/3 miles in 4/3 of an hour. How long does it take for each of them to run 10 miles
Answers
Answer:
Lin 1.454 h
Noah 1.54h
Step-by-step explanation:
From the above, we were given that;
Lin ran 2 3/4 miles in 2/5 an hour. Then, Noah ran 8 2/3 miles in 4/3 an hour
Speed of Lin
V = [(2 3/4)/(2/5)] mph
V = [(11/4)/(2/5)] mph
V = 6.875mph
Speed of Noah
V = [(8 2/3)/(4/3)] mph
V = [26/3)/(4/3))] mph
V = 6.5mph
The time taken by Lin to cover 10 miles
t = 10/6.875
t = 1.454h
The time taken by Noah to cover 10 miles
t = 10/6.5
t = 1.54h

given f (x) = 3x+4, find f (2)
Answers
f(x) = 4x + 4 means that if we put an x into our function, a 3x + 4 come out.
So in this problem, we're putting a 2 into our function which
means that a 3(2) + 1 comes out which simplifies to 6 + 1 or 7.
So f(2) = 7 or the value of the function at 2 equals 7.
[tex]f(x) = 3x + 4[/tex]
Find f(2) by substituting x = 2 in the equation.[tex]f(2) = 3(2) + 4 \\ f(2) = 6 + 4 \\ f(2) = 10[/tex]
Therefore the value of f(2) is 10.
Meaning of f(a) and substitution in functionf(a) means the value of f(x) is ... at x = a. Same goes to the f(2) = 10. It means the value of f(x) = 10 at x = 2.
Answer[tex]f(2) = 10[/tex]

A shop owner offered a 20% discount off the regular price of a mirror. The amount of the discount is $3
Answers
Answer: $15
The original price of the mirror is unknown, so let's call it x.
The discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.

Solving the expression:
We will use simple maths rules to solve the expression
[tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex]
Subtracting 1/2 on both sides and simplify

What is the solution to this system of equations? 2t + w = 10 4t = 20 − 2w A. It has no solution. B. It has infinite solutions. C. It has a single solution: t = 4, w = 2. D. It has a single solution: t = 2, w = 6. E. It has a single solution: t = 6, w = -2.
Answers
Answer:
B. It has infinite solutionsStep-by-step explanation:
Given the system of equations:
2t + w = 10 ..... 1
4t = 20 − 2w ... 2
From 1:
w = 10-2t ...3
Substitute 3 into 2 to have;
4t = 20 - 2(10-2t)
4t = 20-20+4t
4t = 4t
Let t = k
Substitute t = k into 1 and get w;
From 1: 2t + w = 10
2k + w =10
w = 10 - 2k
k can take any integers. This shows that the solution to the equation is infinite

You are Gina versus the 40% of the students to apply. All the students in the University at six, 35% actually enroll. It's 10,000 students apply, how many actually enroll?
Answers
Answer:
1,400 students
Step-by-step explanation:
Calculation for how many actually enroll
First step is to calculate the numbers of students that was accepted
Numbers of students accepted=10,000 students*40%
Numbers of students accepted=4,000 students
Now let calculate the numbers of students that was enrolled
Students enrolled=4,000 students*35%
Students enrolled=1,400 students
Therefore the numbers of students that actually enrolled is 1,400 students

Answer:
60x8 480 -5 475 divided by 2 is 237.5

Answer: 0.234375
Step-by-step explanation:
Conversion a mixed number 2 2/

to a improper fraction: 2 2/3 = 2 2/
3
= 2 · 3 + 2/

= 6 + 2/

= 8/

To find new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/
3
= 6/

b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8
c) Write a previous answer (new numerator 8) over the denominator 3.

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 8/
3

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step the fraction result cannot be further simplified by canceling.
