You have a bag of chocolate candy . ten of them are red,7 are brown,12 are green, and 9 are blue . what is the probability that

Lerok [7]

I believe the answer to your question is 10/37.
The total of candies inside the bag was initially 38. Since a blue candy has already been picked and cannot be picked and cannot be replaced then the total number of candy remaining in the bag is 37. So the probability of choosing a red candy is now 10/37

Answer:

Step-by-step explanation:

The sum of a number and the next the result is is alternating 4 an -4

(-4) +8 = 4

8+(-12) = -4

(-12) + 16 = 4

17)

20)Numerator is increased by 2 Numerator is increased by 1

9th is 18/11 (If 2/3 is considered the first)

9th is 16/10 if 1/1 is considered first)

The sum The sum of each fraction is 3 more than the sum of the previous fraction

2+3 = 5

4+4 = 8 (5+3)

6+5=11 (8+3)

8+6=14 (11+3)......

23)

The next number is 0.7 more than the previous number

5.2/4.5=0.7

4.5/3.8=0.7

3.8/3.1=0.7

The diameter of a road roller is 90 cm and is 2m 10 cm in length. If it takes 400 revolutions to level a playground, find the co

Over [174]

Answer:

The cost of leveling the ground is Rs 5340.6

Step-by-step explanation:

Given:

Diameter of the road roller = 90 cm

Length of the road roller = 2m 10 cm

Total number of number of revolution = 400

Cost of leveling = Rs 2.25 per square meter

To Find:

Total cost of leveling the ground = ?

Solution:

Step 1 : Finding the surface area of the road roller

Converting cm to m

90 cm = 0.9 m

2m 10 cm = 2 + 0.1 m = 2.1 m

Surface area of the road roller = surface are of the cylinder

= $2\pi r h$

r= radius of the road roller

r= $\frac{0.9}{2}$

r=0.45

Now surface area is

=> $2 \times \pi \times 0.45 \times$

=> $6.28 \times 0.45 \times 2.1$

=> $2.826 \times 2.1$

=>5.934

Step 2 : Finding the area of the ground

Total area of the ground = Surface area of the road roller X number of revolutions

=> $5.934 \times 400$

=> 2373.6

Step 3 : Finding the cost of leveling

Total cost of leveling = area of the ground X Cost per square meter

=> $2373.6\times 2.25$

=>5340.6
