Two trains leave stations 560 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour while the other travels at 110
miles per hour. How long will it take for the two trains to meet?
Do not do any rounding.
Answer: the two trains will meet in 2.8 hours
Step-by-step explanation:
Step 1
Speed of train A = 90mph
Speed of train B = 110 mph
Since both trains are travelling towards each other , their effective speed will be= 90 mph + 110mph= 200mph
Step 2
we know that Speed = distance / time
therefore Time = Distance / speed
Distance = 560 miles
Speed = 200 mph
Time = 560miles / 200mph
2.8 hours

Step-by-step explanation:
The right trangular prism has 5 surface areas. 2 of them are triangles and 3 of them are rectangles.
Area of triangle
= 0.5(3/2)(2) = 3/2 square units.
Area of 1st rectangle
= (5/2)(5) = 25/2 square units.
Area of 2nd rectangle
= (3/2)(5) = 15/2 square units.
Area of 3rd rectangle
= (2)(5) = 10 square units.
Total Surface Area
= 2 * (3/2) + (25/2) + (15/2) + 10
= 33 square units. (A)
The width of a recruits 3 cm more than its length. It’s perimeter is 50 cm. Find it’s dimensions.
Answer: Length = 11 cm
Width = 14 cm
Step-by-step explanation:
Let x = Length of the rectangle.
then, width = x+ 3
Perimeter of rectangle = 2 (length +width)
Then, Perimeter = 2 (x+x+3)
= 2 (2x+3)
Since perimeter = 50 cm
[tex]\Rightarrow\ 2(2x+3)=50[/tex]
[tex]\Rightarrow\ 2x+3=25[/tex] [Divide both sides by 2]
[tex]\Rightarrow\ 2x=22\\\\\Rightarrow\ x=11[/tex]
The dimensions are :
Length = 11 cm
Width = 11+3= 14 cm

The length of the sides of a square measure 2x-5. The length of a rectangle measures 2x, and the width measures x + 2. For what value of x is the perimeter of the square the same as the perimeter of the rectangle?
Answer:
[tex]x = 12[/tex]
Step-by-step explanation:
Perimeter of a square:
The perimeter of a square of side x is given by:
[tex]P_s = 4x[/tex]
Perimeter of a rectangle:
The perimeter of a rectangle of length l and width w is given by:
[tex]P_r = 2(l + w)[/tex]
The length of the sides of a square measure 2x-5.
This means that the perimeter of the square is:
[tex]P_s = 4(2x - 5) = 8x - 20[/tex]
The length of a rectangle measures 2x, and the width measures x + 2.
This means that the perimeter of the rectangle is:
[tex]P_r = 2(2x + x + 2) = 2(3x + 2) = 6x + 4[/tex]
For what value of x is the perimeter of the square the same as the perimeter of the rectangle?
This is x for which:
[tex]P_s = P_r[/tex]
So
[tex]8x - 20 = 6x + 4[/tex]
[tex]8x - 6x = 20 + 4[/tex]
[tex]2x = 24[/tex]
[tex]x = \frac{24}{2}[/tex]
[tex]x = 12[/tex]

A sports shop has 80 colored golf balls.
50 of them are orange and the rest are green.
What percent of the balls are green?
Answer:
37.5%
Step-by-step explanation:
The shop has 80 golf balls.
50 of them are orange.
Find the number of green balls:
80 - 50 = 30
Since the rest are green, there are 30 golf balls.
[tex]\frac{30}{80}=0.375*100=\boxed{37.5}[/tex]
37.5% of the golf balls are green.
Hope this helps.
The percentage of balls that are green is given by A = 37.5 %
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage of balls that are green be represented as A
Now , the value of A is
The total number of colored golf balls is = 80 balls
The number of balls that are orange = 50 balls
The number of balls that are green = 30 balls
So , the percentage of balls that are green A = number of balls that are green / total number of colored golf balls
The percentage of balls that are green A = ( 30/80 ) x 100
The percentage of balls that are green A = ( 3/8 ) x 100
The percentage of balls that are green A = 37.5 %
Hence , the percentage of green balls is 37.5 %

Answer:
A: 24°
B: 22°
C: 134°
Step-by-step explanation:
A triangle will always add up to 180°
A + B + C = 180°
(2x + 4) + (2x + 2) + (13x + 4) = 180
2x + 2x + 13x + 4 + 2 + 4 = 180
17x + 10 = 180
17x = 180 - 10
17x = 170
17x/17 = 170/17
x = 10
