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

Step 1: Define
A = 1650 yd²
l = 55 yd
w = unknown
Step 2: Solve for w
Substitute in variables [Area of a Rectangle]: 1650 yd² = (55 yd)(w yd)[Division Property of Equality] Divide 55 yd on both sides: 30 yd = wRewrite: w = 30 ydFind the total amount due on a simple-interest loan if the principal is $5,000 with a rate of 4% for 12 years.
Answer:
$7,400
Step-by-step explanation:
Multiply 5000 by 0.04 so you know how much interest is for 1 year. Then multiply that number by 12. Then add that number to 5000.
White shapes and black shapes are used in a game.
Some of the shapes are circles.
All the other shapes are squares.
The ratio of the number of white shapes to the number of black shapes is 3 : 7
The ratio of the number of white circles to the number of white squares is 4 : 5
The ratio of the number of black circles to the number of black squares is 2 : 5
Work out what fraction of all the shapes are circles.
Answer:
Find the equivalent ratio for the total shapes:
Total Black Shapes : Total White Shapes = 5 : 11
Multiply by 2:
Total Black Shapes: Total White Shapes = 10 : 22

All the members of a school chorus are either students or employees.The ratio of students to employees is 2:5 and the chorus has 70 members. How many employees are members of the chrous?
Answer:
50 employees are members of the chorus
Step-by-step explanation:
Total number of chorus members = 70
ratio of students to employees = 2:5
This means that if the total number of employees were to be divided into 7 parts (2 + 5), 2 parts will be students while 5 parts will be employees. Now let us convert this fraction/ratio to numbers. This is done as follows:
students to employees = 2:5
∴ employees to students = 5:2
Total parts of employees and students = 5 + 2 = 7
∴ Number of employees
[tex]= \frac{5}{7}\ of\ 70\\= \frac{5}{7} \times \frac{70}{1}\\= \frac{350}{7} = 50\ members[/tex]
∴ 50 members are employees, while the remaining 20 are students
100=55+4.5xM please find the value of M.
Answer:
10
Step-by-step explanation:
100=55+4.5*M
4.5M=45
M=10
Answer:
m= 10
Step-by-step explanation:
100=55+4.5m
-55 on both sides
45=4.5m
÷4.5 on both sides
10= m
The perimeter of a rectangle with a length of 10 units which equation can be used to find the width of the rectangle
Answer:
2w + 20 = 55
Step-by-step explanation:
Here is the full question
The perimeter of a rectangle with a length of 10 units is 55 units. Which equation can be used to find the width, w, of the rectangle?
w + 10 = 55
w + 20 = 55
2w + 10 = 55
2w + 20 = 55
The perimeter of a rectangle's formula is = 2 ( length + breadth)
from the question ,
perimeter is 55 and length is 10
2(10 + w) = 55
20 + 2w = 55

A coffee maker priced at $189.99 is on sale for 20% off but then sales tax of 9% and 8% are added to the price after discount. What will be the final sale price with taxes?
RIGHT ANSWER WILL BE MARKED BRAINLIEST
Answer:
20%+9%+8%=37% so 189.99*37/100=70.3$ so 189.99-70.3=119.7$
The final sale price of the coffee maker with taxes is $178.03.
How to calculate the final sale price?To find the final sale price of the coffee maker with taxes, we need to first calculate the discount and then add the tax amounts to the discounted price.
The discount on the coffee maker is 20/100 × $189.99 = $37.998.
So the price of the coffee maker after the discount is:
$189.99 - $37.998 = $152.992.
Then, we need to add the sales tax amounts to this price.
The sales tax amounts are 9/100 × $152.992 = $13.7993
And 8/100 × $152.992 = $12.23936.
The total tax amount is $13.7993 + $12.23936 = $26.03.
Therefore, the final sale price of the coffee maker with taxes is :
$152.992 + $26.03866 = $178.03
This is the final price that the customer will pay for the coffee maker.

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
