Aman, Anna and Tina are participating in the school race. Anna completes a lap in 120 minutes, Aman completes a lap in 240 minutes and Tina completes a lap in 60 minutes. If they all started at the same time, then after how long will they meet again?
Given:
Anna completes a lap in 120 minutes.
Aman completes a lap in 240 minutes
Tina completes a lap in 60 minutes.
To find:
The time after which they will meet again.
Solution:
They all started at the same time. So, the time after which they will meet again is the LCM of time taken by them to complete a lap.
Required time = LCM(120,240,60)
Factors of [tex]120 = 2\times 2\times 2\times 3\times 5[/tex]
Factors of [tex]240=2\times 2\times 2\times 2\times 3\times 5[/tex]
Factors of [tex]60=2\times 2\times 3\times 5[/tex]
So,
[tex]LCM(120,240,60)=2\times 2\times 2\times 2\times 3\times 5[/tex]
[tex]LCM(120,240,60)=240[/tex]
Therefore, after 240 minutes they will meet again.

Kalinda is 68.7 inches tall and wants to know how many inches taller she is than Terrence. If t represents Terrence's height in inches, which expression can she use to find the answer? 68.7 minus t StartFraction t Over 68.7 EndFraction StartFraction 68.7 Over t EndFraction t minus 68.7
Answer:
68.7 - t
Step-by-step explanation:
Here, we are interested in giving the expression that Kalinda can use to know the difference in height between her and Terrence
From the question, Kalinda is 68.7 inches tall while Terrence is t inches tall
To know the difference in their heights, we simply subtract Terrence’s height from Kalinda’a
Mathematically, that would be 68.7 - t

Step-by-step explanation:
write the given equation of the line that passes through the given points
(4,0) and (0,2)
Answer:
y= -1/2x + 2
or y = -0.5x + 2
Step-by-step explanation:
Use the slope formula to get the slope:
(y2-y1)/ (x2-x1)
(2-0)/(0-4)
2/-4
-1/2
Plug in any point in Point-Slope Formula:
y - y1 = m(x-x1)
y- 0 = -1/2 (x -4)
y = -x/2 + 4/2
y= -1/2x + 2

WILL MARK YOU BRAINLIEST HURRY PLZZZ!! I think its C but im not sure
Answer:
B
Step-by-step explanation:
You can rule out all others. A is wrong because a triangle cannot be acute and obtuse at the same time. C is wrong because a polygon dosen't neccassarily need to be a triangle, for example, a polygon is a closed shape, so it could be a rectangle. It isn't D because there are obtuse triangles out there. So, the only one left is B.
The answer is B because if the triangle is a polygon then the conclusion would be that it is either acute or obtuse.
Numbers that cannot be written as a ratio of two integers; decimals that are non-ending and non-repeating. EX: pi
a. Rational Numbers
b. Algebraic term

A ferris wheel has a diameter of 80 meters. How far does a rider travel in one complete rotation around the ferris wheel?
Given parameter:
Diameter of the ferris wheel = 80m
Unknown:
Distance covered in one complete rotation = ?
Solution:
One complete rotation will sweep through the circumference of the wheel.
So,
One complete rotation = Circumference of circle = 2 [tex]\pi[/tex] r
Where r is the radius;
Radius here is [tex]\frac{80}{2}[/tex] = 40m
So circumference = 2 x [tex]\pi[/tex] x 40 = 80[tex]\pi[/tex]
The distance the wheel sweeps through will be 80π m

Answer:
a is 64 b 125 c 36
Step-by-step
so you do 2 times 2 times 2 = 8 because there is a 3 so you multiply it by it self how ever many times the number above it says so after you do that its the same for the other number so they are both 8 so 8 times 8 is 64

Solve for x. Justify each step. Given: 4x-9=99
Answer:
4x-9=99
1. Move -9 to the side with 99 and change the sign
4x=99+9
2. Sum
4x=108
3. Divide 4x by 4 to leave the X alone. Do the same on the other side.
4x/4=108/4
4. Complete the division
x=27
Verification:
4(27)-9=99
108-9=99
99=99 (TRUE)
2. Select the three (3) equations that are equivalent to the equation
X-0.10x+2.5 = 45.5
Show how you determined your answers.
A. 0.90x+2.5=45
B. 0.90x=43
C.0.90x=45.5
D. 1.10x+2.5=45.5
E. 2(x-0.10x+2.5)=91
Answer:
B. 0.90x=43
E.2(x-0.10x+2.5)=91
Step-by-step explanation:
Given equation:
x-0.10x+2.5 = 45.5
Let us simplify this;
Collect like terms;
x - 0.10x = 45.5 - 2.5
Simplify;
0.9x = 43 (Option A)
Also;
x-0.10x+2.5 = 45.5
Simplify by multiplying both sides by 2;
2(x - 0.10x + 2.5) = 2(45.5)
2(x - 0.10x + 2.5) = 91.0
Also;
x-0.10x+2.5 = 45.5
0.9x + 2.5 = 45.5
Those are the three scenarios
Are the expressions –0.5(3x + 5) and –1.5x + 2.5 equivalent? Explain why or why not.
Answer:
It is
-0.5(3x+5)= -1.5x+2.5
Step-by-step explanation:
-0.5(3x+5)
multiply-0.5 with 3x and 5 to get rid of the brackets.
-0.5×3x= -1.5x
-0.5×5= 2.5
-1.5x+2.5
Answer:
Using the distributive property to expand the first expression, you would get -1.5x - 2.5. Since the constant term does not have the same sign as the second expression, the two expressions are not equivalent. Also, if you substitute in a value for x and evaluate each expression, the values will not be equal.

PLZ HELP I WILL MARK BRAILNLEIST!! 20. b) Find the side length of the square. [No label is required.] *
1 point
2x + 5 ft
6x – 11 ft
Your answer
This is a required question
Answer:
The length of one side is 13 feet.
Step-by-step explanation:
To start, a square is 4 sides that are equal in length. This means that when you have a problem like this, you need to set the equations equal to each other like:
[tex]2x+5=6x-11[/tex]
In order to solve a problem like this, with the same variables on different sides, start by subtracting the smaller variable from both sides. In this case, you would be subtracting 2x from both sides, which would leave us with:
[tex]5=4x-11[/tex]
After that, you solve it like a normal one-step equation. Add 11 to both sides.
[tex]16=4x[/tex]
Now, divide both sides by 4 and you will know how much [tex]x[/tex] is worth.
[tex]4=x[/tex]
Now that we know how much [tex]x[/tex] is worth, we can plug that into either of the equations given to us. It doesn't matter which since they are equal to each other.
[tex]2(4)+5[/tex]
That would give us 13.
Answer:
the sides are 13
x= 4
Step-by-step explanation:
2x+5 = 6x-11 subtract five from both sides
2x = 6x-16 subtract 6x from both sides
-4x = -16 divide both sides by -4
x = 4 substitute into original problem
2(4) + 5 = 6(4) - 11
8 + 5 = 24 - 11
13 = 13

Solve the following equation and then check your solution. Show all of your work.
-17+n/5=33
Answer:
n = 250
Step-by-step explanation:
-17 + [tex]\frac{n}{5}[/tex] = 33
[tex]\frac{n}{5}[/tex] = 33 +17
[tex]\frac{n}{5}[/tex] = 50
([tex]\frac{5}{1}[/tex]) ([tex]\frac{n}{5}[/tex]) = 50 *(5)
n = 250
check: -17 + [tex]\frac{250}{5}[/tex] = 33
-17 + 50 = 33
33 = 33
