Answer 1

Answer:

1400 mi

Step-by-step explanation:

The triangle CHE is right, angle CHE is marked as right angle.

We have:

CD= CH = 3960 miDE = 240 miEH = ?

Use Pythagorean theorem to find the value of EH:

CE² = CH² + EH²CE = CD + DE = 3960 + 240 = 4200

Substitute known values and solve for EH

4200² = 3960² + EH²EH² = 4200² - 3960²EH² = 1958400EH = √1958400EH = 1399.42 ≈ 1400 mi (rounded)

To track the reptile population around a lake, researchers marked 36 turtles. A few weeks later, they counted 400 turtles, of which 20 were marked. To the nearest whole number, what is the best estimate for the turtle population?

Answers

Answer: 720

Step-by-step explanation:

From the question, we are informed that cthe researches counted 400 turtles, of which 20 were marked. This implies that 20/400 = 1/20 were marked.

If the researchers wanted to track the reptile population around a lake, and the researchers marked 36 turtles, the estimate of the total population will then be:

1/20 × x = 36

x/20 = 36

x = 20 × 36

x = 720

The turtle population is 720

Answer:

B

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

122° is an exterior angle to both triangles , then

∠ 1 + 75° = 122° ( subtract 75° from both sides )

∠ 1 = 47°

and

∠ 2 + 88° = 122° ( subtract 88° from both sides )

∠ 2 = 34°

Please give me the correct answer.Only answer if you're very good at math.Please don't put a link to a website.​

Answers

Answer:

there are infinitely many solutions

LEFT SIDE/ LEFT EQUATION: if you multiply 1 and (b + 14) together, the result becomes the numerator of the fraction (with 2 being the denominator).

Once you do that, you will notice that both sides/both equations are exactly the same.

Thus, if you put in ANY number for variable b, the solution of both sides/both equations will always be the same and work.

The answer is: "There are infinetly many solutions"

8 in approx

Step-by-step explanation:

Given data

volume = 100 cubic inches

radius= 2 inches

The expression for the volume of a cylinder is given as

v=πr^2h

substitute

100= 12.56h

h= 100/12.56

h=7.9 in

Hence the height is 8in approx

Answers

Answer: [tex]15\times\frac{1}{2}[/tex]

Explanation:

Multiplying by 1/2 is the same as dividing by 2.

For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say [tex]10\times \frac{1}{2} = 5[/tex]

The fraction 1/2 converts to the decimal form 0.5, which means [tex]10 \times \frac{1}{2} = 10*0.5[/tex]

Answers

Answer:

6 * 10^2

Step-by-step explanation:

Simplify : (4.2×10^7)÷(7×10^4)

(4.2 × 10^7) / (7 × 10^4)

From indices : 10^a ÷ 10^b = 10^(a - b)

(4.2 / 7) * 10^(7-4)

0.6 * 10^3

= 6 * 10^2

Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2

The time given depends on the class time and the day of the week.He came up with a few rules to make sure he gets to class on time.The normal drive time for this student is 30 minutes without traffic. He then gives himself 5 minutes to walk across campus to class from the parking lot.However, if he leaves home during the worst morning rush hour, from 6 AM - 7 AM on a weekday, he needs to add 20 minutes to his commute to account for traffic. If he leaves home during the regular morning rush hour, from 7 AM - 8 AM on a weekday, he needs to add 10 minutes to his commute to account for traffic.Mondays have the worst morning traffic, and he should instead add 30 minutes for 6 AM-7AM and 20 minutes for 7 AM 8 AM.On Saturdays and Sundays the student needs to take a different route due to road construction. This adds 6 minutes of travel time.If he leaves during the afternoon rush hour on a weekday, traffic from 4-6PM should add 15 minutes of travel time. Traffic in the afternoon is worst on Thursdays, and should instead add 20 minutes of travel time.If the class is between 9:30 AM and 11 AM he needs to arrive 10 minutes earlier for walking time because the closest parking lots are all full.The program will read data from the screen in the following format:Day_of_the_week hours:minutes AM/PMe.g.Tuesday 12:45 AMSunday 01:52 PMIf the input is not in the correct format the program will prompt the user again for the input.
