Ierofanga [76]

Answer:

The number of boys who play tennis is 36.

Step-by-step explanation:

Let the number of boys who play tennis is x.

number of boys who play cricket = y

x = 3 y..... (1)  

12 boys plays both cricket and tennis.

According to the question,

x - 12 = y + 1 2

3 y - 12 = y + 12

2 y = 24

y = 12

So, the number of boys who plays tennis is x = 3 x 12 = 36.

(05.08)Solve for x: 7 over 8 minus 1 over x equals 3 over 4.
NemiM [27]

If you are asking 7/8 - 1/x= 3/4,

first put 3/4 to 6/8 to make it easier.

Move the 7/8 over to the right. You will get 1/x=-1/8.

Simplify, it is x=-8.

Check=7/8 - 1/8=6/8

It checks out.

Find the probability that a point is chosen randomly inside the rectangle is in each given shape...
Arlecino [84]

By taking the quotients between the areas, we see that:

  • a) P = 0.275
  • b) P = 0.85

<h3>How to find the probabilities?</h3>

First we need to find the areas of the 3 shapes.

For the triangle, the area is:

T = 3*5/2 = 7.5

For the blue square, the area is:

S = 3*3 = 9

For the rectangle, the area is:

R = 10*6 = 60

Now, what is the probability that a random point lies on the triangle or in the square?

It is equal to the quotient between the areas of the two shapes and the total area of the rectangle, this is:

P= (7.5 + 9)/60 = 0.275

b) The area of the rectangle that is not the square is:

A = 60 - 9 = 51

Then the probability of not landing on the square is:

P' = 51/60 = 0.85

(ASAP NEED TO SUBMIT NOW!!!) What is the Unit Rate for each cyclist?
sveta [45]

Answer:

Unit rates for cyclist A , B, C , D are 12 mile/ hour , 5 mile/hour, 9 mile/hour and 10 mile/hour respectively. Cyclist A is the fastest among the four.

Step-by-step explanation:

Cyclist A can ride 24 miles in 2 hours

so, cyclist A's  unit rate is, \frac {24}{2}

                                       = 12 mile/hour

Cyclist B's unit rate is, \frac {5}{1}

                                 = \frac {10}{2}

                                 = \frac {15}{3}

                                =  5 mile/hour

Equation for cyclist C is, y = 9x ,

so, cyclist C's unit rate is , 9 mile/hour

Slope of the graph for cyclist D,

= \frac {10 -0}{1 - 0}

 = 10

So cyclist D's unit rate is, 10 mile/hour

So, cyclist  A is the fastest.
