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 %

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]

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)

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

In a long-distance relay contest, Team A completed the race in 5 2/3 hours, and Team B completed the race in 294 minutes. How much longer did it take Team A to complete the race than Team B? Answer the question in hours first, and then in minutes.
Answer:
46 minutes.
Step-by-step explanation:

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
