The probability of “landing” in the shaded region to the nearest hundredth is equal to 0.79 or 79.0%.

<h3>How to determine the probability?</h3>

First of all, we would determine the area of the given geometric shapes.

For the square, we have:

Mathematically, the area of a square can be calculated by using this formula;

Area = x²

Area = 50²

Area = 2500 ft².

For the circle, we have:

Mathematically, the area of a circle can be calculated by using this formula;

Area = πd²/4

Area = (3.142 × 50²)/4

Area = 1,963.75 ft².

Now, we can determine the probability as follows:

Probability = 1963.75/2500

Probability = 0.79 or 79.0%.

<h3>When the side length is 40 ft.</h3>

Area = x²

Area = 40²

Area = 1600 ft².

For the circle, we have:

Area = πd²/4

Area = (3.142 × 40²)/4

Area = 1256.8 ft².

Probability = 1256.8/1600

Probability = 0.79 or 79.0%.

Which of these points, if any, is the midpoint of FJ?
ivanzaharov [21]

The mid-point of FJ is the number right in the middle of FJ. Find the mean of F & J. Add regardless of sign

4 + 6 = 10

10/2 = 5

Add 5 to -4

5 + -4 = 1

H is your midpoint

True. As long as AB and BC are on the same line, AB + BC = AC

hope this helps

A 555-mile, 5-hour plane trip was flown at two speeds. For the first part of the trip, the average speed was 105 mph. Then the t
Pepsi [2]

Answer:

Hence Distance traveled at speed 115 mph is <u>345 miles</u> and Distance traveled at speed 105 mph is <u>210 miles</u>.

Step-by-step explanation:

Given:

Total Distance = 555 mile

Total time = 5 hour

Let time taken to travel at 115 mph be t

So Time taken to travel at 105 mph will be equal to difference between Total time and  time taken to travel at 115 mph.

Time taken to travel at 105 mph = 5-t

Distance traveled in speed 105 mph will be equal to speed multiplied by time taken to travel at 105 mph.

Framing in equation form we get;

Distance traveled in 115 mph = 115t

Also;

Distance traveled in speed 105 mph will be equal to speed multiplied by time taken to travel at 105 mph.

Framing in equation form we get;

Distance traveled in 105 mph = 105(t-5) = 105t - 525

Now Total Distance traveled is equal sum of Distance traveled in 115 mph and Distance traveled in speed 105 mph

115t-(105t-525)=555\\\\115t-105t+525=555\\\\10t+525=555\\\\10t=555-525\\\\10t=30\\\\t=\frac{30}{10}=3

Time taken to travel at 115 mph = 3 hrs.

Time taken to travel at 105 mph = 5-t=5-3=2\ hrs

Now Distance traveled in 115 mph = 115t = 115 \times 3 = 345\ miles

Distance traveled in 105 mph = 105(5-t) = 105(5-3)= 105\times 2 = 210\ miles

Hence Distance traveled at speed 115 mph is <u>345 miles</u> and Distance traveled at speed 105 mph is <u>210 miles</u>.
