is 3 1/4 a rational number

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

Answer:

h(-2) = 13

h(5) = -1

Step-by-step explanation:

Given the function

h(x) = -2x + 9

Evaluating at x = -22

substitute x = -2

h(-2) = -2(-2) + 9

h(-2) = 4 + 9

h(-2) = 13

Therefore,

Evaluating at x = 5

Given the function

h(x) = -2x + 9

substitute x = 5

h(5) = -2(5) + 9

h(5) = -10 + 9

h(5) = -1

Therefore,

Answer:

$280

Step-by-step explanation:

Step one

Given data

A mechanic makes $350 /week

20% of his income is deducted for taxes

Required

the mechanic's take-home pay for the week

Step two:

let us find 20% of $350

=20/100*350

= 0.2*350

=$70

Therefore the take-home pay is

= 350-70

= $280

Answer:

[tex]\frac{6}{5}[/tex]

Step-by-step explanation:

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

~~~~~~~~~~~

(3, 3)

( - 2, - 3)

m = [tex]\frac{-3-3}{-2-3}[/tex] = [tex]\frac{6}{5}[/tex]

Answer:

232.96

Step-by-step explanation:

18.2-12.8=5.4

12.8•12.8=163.84

5.4•12.8=69.12

163.84+69.12=232.96

Answer:

Undefined

Step-by-step explanation:

The graph shows a vertical line. All vertical lines have a undefined slope.

This is because that while using the slope formula you will end of with the denominator being 0. You cannot divide by zero.

Hope this helps!

Answer:

5^3

Step-by-step explanation:

125= 5*25

25=5*5

5 is a prime number and there are 3 of them so the answer in index notation will be 5^3

Answer:

A?

Step-by-step explanation:

A is the only one that makes sense, becaues 150% of 500 is 750.

150/100 = 150%

5/5, I believe, just represents the 5 in 500.

Answer:

Answer:

Solving the given expression [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex] we get 0=0

Step-by-step explanation:

We need to solve the expression: [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex]

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

[tex]x+\frac{1}{2}-x-\frac{1}{2}=\frac{1}{2}-\frac{1}{2}\\x-x=0\\0=0[/tex]

Solving the given expression [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex] we get 0=0

So, the expression is true for all values of x. there will be infinite solutions to the system.

Answer:

6/25

Step-by-step explanation:

2 1/2 = 5/2

3/5 / 5/2 = 3/5 * 2/5 = 6/25

Answer:

Step-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

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

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]

[tex]f(2) = 3(2) + 4 \\ f(2) = 6 + 4 \\ f(2) = 10[/tex]

Therefore the value of f(2) is 10.

f(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.

[tex]f(2) = 10[/tex]

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:

90 (its a square no?)

Step-by-step explanation:

Answer:

2x - 3y + 8

Step-by-step explanation:

If you combine like terms

(In this case "y" and "-4y")

You get "-3y"

The rest of the equation stays the same, as there are no more like terms.

Therefore the answer is the D.

Answer:

3 3/4

Step-by-step explanation:

3/4 * 1/5

First you would turn 1/5 into a reciprocal

Now your equation would be 3/4 *5/1

Now you multiply 3/4 * 5/1

15/4

Now find 15/4 as a mixed number

15/4 as a mixed number would be 3 3/4

Therefore there are 3 3/4 1/2 cup servings in a 3/4 cup of ice
