Unit Rates
Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in hour. At the airport, they exited the car and walked for hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.

Answer the following questions about Kiley’s trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that Kiley is at rest (that is, not moving).

In this task, you will write the ratio of miles to hours for each leg of Kiley’s trip. You will then, express the ratio as a decimal number. Next, you will find the unit rate in miles per hour (mph) for each leg of the trip. If your unit rate includes a repeating decimal number, you must indicate which digits repeat (for example, write when the 3 repeats.) A description of each leg is listed below in parts A through F.

Part A
the car ride from Kiley’s house to the airport

Part B
at the airport, the walk from the car to the waiting area by the gate

Part C
the leg from the waiting area to the airplane’s takeoff

Part D
the airplane ride

Part E
the walk from the airport to the cab

Part F
the cab ride

Answer:

[tex]\huge\boxed{\sf y = 30}[/tex]

Step-by-step explanation:

Given that:

y ∝ x

Turning proportionality into equality by putting the constant 'k'

y = kx ---------------------(1)

We know that y = 24, when x = 8

24 = k(8)

Divide both sides by 8

24 / 8 = k

3 = k

OR

k = 3

Now, Finding y when x = 10

Put x = 10 and k = 3 in Eq. (1)

y = (3)(10)

y = 30

{put the given value of j and k in the given equation.. and solve ....}

Answer:

0.45

Step-by-step explanation:

This question is asking you to find the value of the equation when j = -4 and when k = -0.7. To do this, we must substitute j with -4 and k with -0.7:

(-4 * -0.7 - 1) / -4

= (2.8 - 1) / 4

= (1.8) / 4

= 0.45

A point estimate of the percentage of defectives in all manufactured bulbs is the Sample proportion.

p'= x / n where x is the number of successes and n is the sample size. The variable p is the sample ratio and serves as a point estimate of the true ratio of the population.

Point estimation for population parameters is a single value for statistics. For example, the sample mean x is a point estimate of the population mean μ. Similarly, the sample ratio p is a point estimate of the population ratio P.

The average point estimate for the population is obtained by calculating the average of the samples taken from the population. The average calculation is the sum of all samples divided by the number of values.

Answer:

35 LCD monitors.

Step-by-step explanation:

The ratio is 2:5, which means the total amount of parts is 7 (2 + 5 = 7).

There are 49 monitors in all. Divide 49 with 7:

49/7 = 7

Each part has 7 monitors within. Remember, there are 5 parts of LCD monitors compared to 2 CRT monitors. Multiply 7 with 5:

7 x 5 = 35.

There are 35 LCD monitors, and 14 CRT monitors.

Answer:

side a = 30 feet long.and side b = 30-14 = 16 feet long.

Step-by-step explanation:

Right triangle, with sides a, b=a-14 and h=34

By Pythagorean rule, h2 = 342 = a2 + b2 = a2 + (a-14)2 ==> a2 + a2 - 28a + 196

Simplify to get 1156 = 2a2 - 28a + 196

Subtract 1156 from both sides to get 2a2 - 28a - 960 = 0

Divide all terms by 2: a2 -14a - 480 = 0

Use quadratic equation to find that a = 30 or a = -16.

a = -16 will not work.

Therefore side a = 30 feet long.and side b = 30-14 = 16 feet long.

Check: 302 + 162 = 900+256=1156. SQRT(1156) = 34 feet, the given hypotenuse.Right triangle, with sides a, b=a-14 and h=34

By Pythagorean rule, h2 = 342 = a2 + b2 = a2 + (a-14)2 ==> a2 + a2 - 28a + 196

Simplify to get 1156 = 2a2 - 28a + 196

Subtract 1156 from both sides to get 2a2 - 28a - 960 = 0

Divide all terms by 2: a2 -14a - 480 = 0

Use quadratic equation to find that a = 30 or a = -16.

a = -16 will not work.

Therefore side a = 30 feet long.and side b = 30-14 = 16 feet long.

Check: 302 + 162 = 900+256=1156. SQRT(1156) = 34 feet, the given hypotenuse.

The side length of the other sides is 30 feet and 16 feet if the shorter leg of a right triangle is 14 feet less than the other leg.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

It is given that:

The shorter leg of a right triangle is 14 feet less than the other leg.

From the Pythagoras theorem:

hypotenuse² = perpendicula² + base²

perpendicular = base - 14

34² = (base - 14)² + base²

34² = base² - 28base + 196 + base²

2base² - 28base - 960 = 0

base = 30, -16

side length cannot be negative

base = 30 feet

The length of another leg:

perpendicular = 30 - 14 = 16 feet

Thus, the side length of the other sides is 30 feet and 16 feet if the shorter leg of a right triangle is 14 feet less than the other leg.

Answer:

B and D are the correct answer

Step-by-step explanation:

I took the test

The difference in the starting salaries is $2,500 and Luisa will make more money in the first 8 years thus (B) and (D) are correct.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

Given salary of Luisa by function,

y = 36,000(1.025)^x

The starting salary of Luisa,

x = 0 → y = 36000(1.025)^0 = $36000

Starting salary Damon = $38500

Difference = 38500 - 36000 = $2500

Amount of money that Luisa make in first 8 years ⇒

36,000(1.025)¹ + 36,000(1.025)² + ...up to 8 times

Amount of money that Damon makes in first 8 years ⇒

38500 + (38500 + 800) + (38500 + 2 × 800) + ...up to 8 times.

The rate of increment of Luisa > Damon

Hence "The difference in the starting salaries is $2,500 and Luisa will make more money in the first 8 years".
