divide rupee 560 between ramu and muni in the ratio of 3:2
Step-by-step explanation:
Let the divided amount between ramu and muni be 3x and 2x respectively.
Then
3x + 2x = 560
5x = 560
x = 560/ 5
x = 112
Amount received by Ramu
= 3 * 112 = 336
Amount received by muni
= 2 * 112 = 224

Answer:
The equation would help determine the cost 1 rubber stamps will be:
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
Step-by-step explanation:
Let x be the cost of 11 rubbers.
As the cost of 5 rubber stamps is $9.70.
Thus, the cost of 11 rubbers can be determined using the proportional ratios.
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
BONUS! let us solve to check
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
switch sides
[tex]\frac{x}{11}=\frac{9.7}{5}[/tex]
Multiply both sides by 11
[tex]\frac{11x}{11}=\frac{9.7\cdot \:11}{5}[/tex]
Simplify
[tex]x=21.34[/tex]
Thus, the cost of 11 rubber stamps: x = $21.34
Therefore, the equation would help determine the cost 1 rubber stamps will be:
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
VERIFICIATIONGiven
The cost of 5 rubber stamps = $9.70
Thus,
The cost of 1 rubber stamps = 9.70 / 5
= $1.94
If the cost of 1 rubber stamp = $1.94
The cost of 11 rubber stamps = 11 × 1.94
= $21.34

A park is in the shape of a rectangle 300 feet long 50 feet wide Amaya is standing at one corner of the park at point x he then walks in a straight line to the opposite corner at point y how far does he walk rounded to the nearest tenth
Answer:
[tex]304.1\ \text{feet}[/tex]
Step-by-step explanation:
The dimensions of the rectangle are 300 feet long 50 feet wide
The length between [tex]x[/tex] and [tex]y[/tex] will be the length of the diagonal of the rectangle.
Length of the diagonals can be found using the Pythagoras theorem
[tex]\sqrt{300^2+50^2}=304.138\approx 304.1\ \text{feet}[/tex]
The distance walked from [tex]x[/tex] to [tex]y[/tex] is [tex]304.1\ \text{feet}[/tex].

times its birth
weight. How many pounds did the baby weigh at
the end of 8 months?
Answer:
The baby weighed 14.5 pounds at the end of 8 months
Step-by-step explanation:
Proportions
We know a baby weighed 7.25 pounds at birth.
It's given at the end of 8 months, the baby weighed twice its birth weight.
This means the baby weighed 2*7.25 = 14.5 pounds at the end of 8 months.
The baby weighed 14.5 pounds at the end of 8 months

The area of a rectangular fence is 500 square feet. If the width of the
fence is 20 feet, then find its length.
Answer
Here the area and the width of the rectangular fence are given. We have to find length of the fence.
( diagram )
The area A of a rectangle is given by the formula A=lw where l is the length and w is the width.
Given that area is 500 square feet and width is 20 feet.
Substituting values in formula,
⇒500=l×20
⇒20/500
= 20/1×20
[ Dividing both sides by 20 ]
⇒l=25 feet
∴ length of rectangular fence is 25 feet.
Hence, the answer is 25.

The length of a rectangular birthday party invitation is 1 inch less than twice its width. The area of the invitation is 15 square inches.
The length of a rectangular birthday party invitation is 9 inch.
The length of a rectangular birthday party invitation is 1 inch less than twice its width.
Area of the invitation 15 square inches.
what is the area of the rectangle?
A=length× width
That is,the area of a rectangle is length times width.
let x be the width rectangle
width = x
length = 2x - 1
[tex]Area= 15 square inches[/tex]
Using these variables, set up the equation for area.
x(2x - 1) = 15
Solve the equation for x.
[tex]2x^{2} - x = 15[/tex]
Subtract 21 on both sides of the equation.
[tex]2x^{2} - x - 15=0[/tex]
Which method we use to factor the polynomial?
FOIL method
Factor using FOIL, if possible.
(2x +5)(x - 5) = 0
Set the factors equal to zero and solve for x.
2x = -5 and x - 5 = 0
x =- 5/2 or x = 5
x =- 2.5 or x=5
Since we cannot accept a negative value for dimensions, we accept the positive value of x:
x = 5
Therefore,
Length = 2(5) - 1
Length = 10-1
Length = 9
Therefore we get the length is 9 inch

At a swim meet 20 medals were a warded. Four were gold metals 45% of the metals were silver the rest were bronze. What percent of the medals awarded were bronze
Answer:
35%
Step-by-step explanation:
To figure out the percentage of bronze medals, we must figure out the percentages of the gold and silver medals first.
We already know that 45% of the medals were silver.
We know that 4 of the 20 medals were gold.
4/20 as a percentage would be 20/100, or 20%.
So, 20% of the medals were gold, and 45% of them were silver.
45% + 20% = 65%
100% - 65% = 35%
So, 35% of the medals awarded were bronze.
