In a bag there are 10p coins, 20p coins and 50p coins
there are three fewer 20p coins that 10p coins
theres are seven more 50p coins than 10p coins
altogether there are 61 coins
work out the total value of the 20p coins give your answer in pounds(£)
Answer:
Approximately 25p (please change to pounds by yourself I'm not European, sorry).
Ok so according to my research its 100 pence to one pound. Which will mean that 25p in pounds is £ 00.25
Step-by-step explanation:
let's say:10p= x20p= y 50p= z '3 fewer 20p (y) coins than 10p (x) coins'Therefore:y-3=x and y= x+3'7 more 50p coins (z) than 10p coins (x)'That is:z+7= xz= x-7'altogether are 61 coins'x+y+z = 61 (substitute for y and z)x + x + 3 + x - 7 = 61x+x+x+3-7 = 613x - 4= 613x= 61 + 43x=65x= 65÷3x= (approximately) 21.6 (Substitute x in y and z)y = x+3y = 21.6 + 3 = 24.6 (approximately 25)z = x -7z= 21.6-7= 14.6 (approximately 15)y= 20p y= 25p (approximately)Check x+y+z= ?21.6 + 24.6 + 14.6= 60.8 (approximately 61)(Sorry I couldn't change to pounds)

Answer:How to Write 0.17 or 17% as a Fraction?
Decimal Fraction Percentage
0.2 20/100 20%
0.19 19/100 19%
0.18 18/100 18%
0.17 17/100 17%
Step-by-step explanation:
The percentage value ( 17 % ) as a fraction is A = 17/100
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the percentage value be represented as A
Now , the value of A = 17 %
And , percent" means "per hundred".
So, 17% means 17 per hundred, or 17/100
Hence , the fraction is A = 17/100

Cube-shaped shipping boxes, like the one shown, are packed into a van. They form a solid without gaps or overlaps that is 3 feet long, 2 feet wide, and 3 feet tall. What is the volume of the solid formed?
Answer: 18 feet
Step-by-step explanation:
You didn't put the picture but based on your question, the volume would be calculated by multiplying the length by the width and the height. This would be:
= Length × Width × Height
= 3 × 2 × 3
= 18 feet
Two equations are shown:
• Equation 1: 3/4(x– 12) = 12
Equation 2: 3/4y - 12 = 12
.
Solve each equation. Then, enter a number in each box to make this statement true.
The value of x is:
The value of y is:
Answer:
The value of x is: 28
The value of y is: 32
Step-by-step explanation:
Let us solve the question
∵ [tex]\frac{3}{4}[/tex] (x - 12) = 12 ⇒ (1)
→ Multiply each term in the bracket by [tex]\frac{3}{4}[/tex]
∴ [tex]\frac{3}{4}[/tex] (x) - [tex]\frac{3}{4}[/tex] (12) = 12
∴ [tex]\frac{3}{4}[/tex] x - 9 = 12
→ Add 9 to each side
∵ [tex]\frac{3}{4}[/tex] x - 9 + 9 = 12 + 9
∴ [tex]\frac{3}{4}[/tex] x = 21
→ Divide both sides by [tex]\frac{3}{4}[/tex] to find x
∴ x = 28
∵ [tex]\frac{3}{4}[/tex] y - 12 = 12 ⇒ (2)
→ Add 12 to both sides
∴ [tex]\frac{3}{4}[/tex] y - 12 + 12 = 12 + 12
∴ [tex]\frac{3}{4}[/tex] y = 24
→ Divide both sides by [tex]\frac{3}{4}[/tex] to find y
∴ y = 32

A rectangular prism is 1 inch long and 2 inches wide. Its volume is 12 cubic inches. What is the height of the rectangular prism?
Answer: 6 inches
Explanation:
12 = 1(2)h
12 = 2h
12 ÷ 2 = 2h ÷ 2 (isolating the H term)
6 = h
A certain ball is dropped from 204 centimeters, and has a rebound factor of 72% (The height of the ball after each bounce is 72% of the height of the bounce before.). Which equation represents the relationship between the the number of bounces, n, and height, h, in centimeters? Group of answer choices
Answer:
The equation that represents the relationship between the number of bounces and the height is [tex]H = 204\cdot 0.72^{n}[/tex].
Step-by-step explanation:
According to this exercise, we notice that maximum height of the ball ([tex]H[/tex]), measured in centimeters, is reduced at geometric rate and as a function of the number of bounces ([tex]n[/tex]), with no unit, which is defined by geometric progression:
[tex]H = H_{o}\cdot r^{n}[/tex] (1)
Where:
[tex]H_{o}[/tex] - Initial height of the ball, measured in centimeters.
[tex]r[/tex] - Bounce factor, no unit.
If we know that [tex]H_{o} = 204\,cm[/tex] and [tex]r = 0.72[/tex], then the equation that represents the relationship between the number of bounces and the height is:
[tex]H = 204\cdot 0.72^{n}[/tex] (2)
Solve for x. 8x + 1 = 5x + 22
Answer:
Step-by-step explanation:
8x + 1 = 5x + 22
8x - 5x + 1 = 5x- 5x + 22
3x + 1 = 22
3x + 1 - 1 = 22 - 1
3x = 21

if correct will mark brainliest
Answer:
y = -x + 9
Step-by-step explanation:
✔️Find the slope using (9, 0) and (7, 2):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 0}{7 - 9} = \frac{2}{-2} = -1 [/tex]
Slope (m) = -1
✔️Find the y-intercept (b):
The line intercepts the y-axis when y = 9. Therefore, y-intercept (b) = 9
✔️Substitute m = -1 and b = 9 into y = mx + b
Thus,
y = -1(x) + 9
y = -x + 9

The price of a video game was reduced from $60 to $45. By what percentage was the price of the video game reduced?* O 15% O 25% O 75% 40% M
Answer:
25
Step-by-step explanation:
The new price, $45, can be expressed as a percentage of $60 by taking it as a fraction of $60, converting to a decimal value, and multiplying by 100%. $45/$60=3/4=0.75, 0.75x100%=75%. So since 100%-75%=25%, the value was reduced by 25%.
simplify the expression IabI if a>0 and b>0
Answer:
Step-by-step explanation:
The "ab" inside absolute value has to go out positive, such as |-2|=2
Since both the a and b values are positive, the value of |ab| should be "ab"
For example:
a=2
b=3
|ab| = |2*3| = |6| = 6
