Answer 1

Answer:

5.5 hours

Step-by-step explanation:

1. Understand

A person can travel at the speed of 40 miles per hour (mph). If the speed is increased by 50%, how long will it take to cover 330 miles?

a. What is asked?  How long will it take to cover 330 miles travelling at a speed 50% greater than 40 mph

b. What are the given facts?

Current Speed = 40 mph

New Speed = 40 mph + 50% of 40 mph

Distance = 330 miles

2. Plan

Calculate the new speed and then use the two speeds to calculate time based on Distance = Speed x Time

What is the formula to solve the problem?

Distance = Speed x Time

3. Solve

Show your solution.

Original Speed = 40 mph

New Speed = 40 + (0.5)*(40):  New = 60 mph

Time at New Speed is:

Distance = Speed x Time

330 miles = (60 mph)*(Time)

Time = (330 miles)/(60 miles/hour)

Time = 5.5 hours

4. Check

Distance = Speed x Time

How far does a person travel going 60 miles/hour for 5.5 hours?  Is it 330 miles?

Distance = (60 mph)*(5.5 hours)

Distance = 330 miles

YES

Find all possible values of x. The triangles are NOT drawn to scale.

Answers

Answer:

0 < x < 28

Step-by-step explanation:

The triangle inequality theorem states that the sum of any two sides of the triangle should be greater than the third side.

Therefore,

0 < x < 28

All the possible values of x are 26 < x < 28.

What is Triangle?

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

So a triangle has three sides.

We have the triangle inequality theorem which states that,

The length of any side of the triangle is always less than the sum of the other two sides.

And the range of the possible measure of the third side is the sum and the difference of the other two sides.

So x < 27 + 1 = 28

and,

x > 27 - 1 = 26

So 26 < x < 28

Hence the measures of third side is 26 < x < 28.

Answers

The triangle with side lengths of 10 in., 12 in., and 15 in. is acute because 10^2 + 12^2 > 15^2

What is the acute angle?

An acute angle is defined as the measure of an angle that is less than 90 degrees.

The side lengths of the triangles are 10, 12 and 15

The smallest side lengths are: 10 and 12

The sum of the squares of these side lengths is

[tex]10^2 + 12^2[/tex]

For the triangle to be acute, then the following must be true

[tex]10^2 + 12^2 > 15^2[/tex]

Evaluate the exponents

[tex]244 < 255[/tex]

The above inequality is true.

Hence, the triangle is acute because 10^2 + 12^2 > 15^2

A screening test for a newly discovered disease is being evaluated. In order to determine the effectiveness of the new test, it was administered to 900 workers. 150 of the individuals diagnosed with the disease tested positive. A negative test finding occurred in 60 people who had the disease. A total of 50 persons not diseased tested positive for it. Assume the prior probability is not known. What is the overall accuracy of the test

Answers

The overall accuracy of the screening test for a newly discovered disease is being evaluated for this case is 87.78% approximately.

What is the accuracy of a test?

Accuracy of a test is the ratio of the correct results to the total results the test gives.

Thus, we have:

[tex]\rm Accuracy =\dfrac{\text{Total number of correct results}}{\text{Total number of results}} = \dfrac{TP + TN}{TP + FP + TN + FN}[/tex]

where T represents True, F represents False, N represents Negative, and P represents Positive. The negativity and positivity are the results of the test.

For this case, we're specified that:

The test is happening for diagnosis of a newly discovered disease.Total number of tests done = total number of workers administered = 900True positive (TP)= test result positive (ie test saying that the person has disease) when disease is actually present (that actual presense is known by some other method, and here we're evaluating the quality of 'disease testing procedure' in consideration) = 150 in count.False Negative (FP)= test result negative (no disease detected by the test) when person is diseased in reality = 60False positive (FN) = test result positive when person has no disease in reality = 50As total 900 tests were done, so we get: True negative(TN) = 900 - TP - FP - FN = 640

(as each test result would be one of the TP, TN, FP, FN and these four no test result can lie in more than one of these categories).

Now, we have:

true results = TP + TN = 640 + 150 = 790

total results = 900

Thus, we get:

[tex]\text{Test accuracy} = \dfrac{TP + TN}{TP + FP + TN + FN} = \dfrac{790}{900} \approx 0.8778 = 87.78%[/tex]

Thus, the overall accuracy of the screening test for a newly discovered disease is being evaluated for this case is 87.78% approximately.

Answers

Step-by-step explanation:

first of all, your teacher wrote nonsense in the answer options : an area is always given in squared units. never in cubed units (which would be volume).

the area is : 1/2 × perimeter × apothem

the perimeter is simply 12 × 5 = 60 meters.

apothem = (a/2)×cot(pi/12) = 5/2 × cot(pi/12) =

= 9.330127019... meters

so the area is

1/2 × 60 × 9.330127019... = 279.9038106... m²

therefore, the third answer option is correct (although it is m², and not m³).

by the way, you have question 3 wrong. I answered this with the correct apothem calculation in the explanation for question 4.

A car rental company charges $28 per day for a rented car and $0.50 for every mile driven. A second car rental
company charges $20 per day and $0.75 for every mile driven. What is the number of miles at which both
companies charge the same amount for a one-day rental?

Answers

Answer:

56 miles

Step-by-step explanation:

According to the question, lets say the miles at x they charge the same rental

       34 + 0.50x = 20 + 0.75x (Solve equation)

       0.75x - 0.50x = 34 - 20

       0.25x = 14

       x = [tex]\frac{14}{0.25}[/tex]

       x = 56

So at 56 miles, they charge the same rental.
