Answer:

2/3 Rupees

Step-by-step explanation:

Lets say Chocolate is C and a rupee is R.

Then, 15C = 10R. We can simplify to 3C = 2R. Now we divide both sides by Three to get C = 2/3R, which means a chocolate is 2/3 of a rupee!

Answer:

Number of baskets with 12 pieces of fruit: 15

Number of baskets with 15 pieces of fruit: 45

Step-by-step explanation:

25% x 60 = 0.25 x 60 = 15

75% x 60 = 0.75 x 60 = 45

The complete model for the given question is;

Number of fruit baskets that contain 12 fruits = 15 baskets

Number of fruit baskets that contain 15 fruits = 45 baskets

We are told that he bought 60 fruit baskets.

Percentage of the fruit baskets that have 12 pieces of fruit = 25%

Percentage of the fruit baskets that have 15 pieces of fruit = 75%

Thus;

Number of fruit baskets that contain 12 pieces of fruit = 25% × 60 = 15 baskets

Number of fruit baskets that contain 15 pieces of fruit = 75% × 60 = 45 baskets

The percentage of boys in the class is 33.3%

If the class has 30 students and 20 girls then;

Boys = (30 - 20 = 10)

Percentage that are boys = (no.of boys/total students) x 100

10/30 * 100 = 33.3%

The percentage is a relative fee indicating the hundredth component of any amount. One percentage (symbolized 1%) is one centesimal part; as a result, 100 percent represents everything and 2 hundred percent specifies twice the given amount. percentage. associated subjects: mathematics percentile.

Multiply the number by means of 100. If you are required to convert a decimal number like 0.57 to a %, you simply multiply it through one hundred. that is 0.57 x 100 = 57. therefore, 0.57 as a percent equals 57%.

Answer:

(-3, -7)

Step-by-step explanation:

2x - y =  7                 multiply by -1  ⇔     -2x + y = -7

1x - y = 10                Do not change ⇔     1x -  y =  10  

                                                                     -x   = 3

                                                                      x = -3

Use the second equation to solve on y when x = -3

-1x - y = 10

-1(-3) - y = 10

 3 - y = 10

    -y = 10 - 3

    -y  = 7

     y = -7                         Solution:  (-3, -7)

Answer:

75

Step-by-step explanation:

A = π r^2

A = Area of the circle which is in this question unknown

r = radius of the circle (which is the length of straight line from the center of the circle to any point on the circumference of the circle) and in this question is equal to 5 in

π = irrational number equal to 3.14159... but here you have told to use it as 3

A = π r^2

*plot the information we have get( r = 5 in and π = 3 ) in the equation above

A = (3)(5)^2

A = (3) (25)

A = 75 in^2
