Answer:

  about 26.6 times

Step-by-step explanation:

The circumference of the ball is found from ...

  C = 2πr = 2π(4.3 in) ≈ 27.02 in

There are 12 inches per foot, so the 60 foot distance of interest is ...

  (60 ft)×(12 in/ft) = 120 in

In terms of ball circumference, that distance is ...

  (120 in)/(27.02 in/rotation) ≈ 26.6 rotations

If the ball starts rotating at the foul line, it will turn about 26.6 times before reaching the head pin.

In a basket of apples, 12% of them are rotten and 66 are in good condition. Find the total number of apples in the basket.​
olganol [36]
<h3>Solution:</h3>

<u>Let the total number of apples in the basket be m</u>

<u>12% of the apples are rotten, and apples in good condition are 66</u>

Therefore, according to the question,

88\% \:  of \:  m= 66

→ \frac{88}{100}× m = 66

→ m = \frac{(66  \times  100)}{88}

→ m = 3  \times  25

→ m = 75

<u>Therefore, total number of apples in the basket is 75.</u>

nirvana33 [79]

Answer:

Ans.    64 cm

Step-by-step explanation:

we have to use the ratio of actual distance and distance on projection here.

Given,

Ratio of distance in projection and actual distance is  1:200,000

That means, 1 cm in projection will be 200,000 cm in actual distance.

Here,

Actual distance is 128 km.

we know, 1 km=100,000 cm

Now,  128 km=128,00,000 cm

So, actual distance is 128 00 000 cm.

Since, 200000 cm in actual distance means 1 cm in projection.

So,

for 12800000 cm in actual distance means 12800000/200000 cm in projection.

So, in the screen distance will be-

12800000 / 200000

=64 cm
