Which car among the 3 had the best gas mileage?

Answers

Answer 1

Answer:

Car C  with a gas mileage of 18.18 mpg

Step-by-step explanation:

Compute mileages by the formula: Miles Driven/Gas Consumed and choose the highest value

Car A:  500 /  33.4 = 14.97 mpg

Car B : 43 / 2.5  = 17.2 mpg

Car C: 100 / 5.5 = 18.18 mpg

calculate the volume of air in liters that you might inhale (and exhale) in 8.00 hours. assume that each breath has a volume of 0.475 liters, and that you are breathing 18 times a minute.

Answers

The volume of air in liters that might inhale (and exhale) in 8.00 hours is 4060.8 litres.

What is defined as the unitary method?The unitary method is one that involves determining the value of a single unit and then calculating the value of a required number of units based on that value.The unitary method's formula is to identify the value of a specific unit and then multiply that value by the number of units to arrive at the required value.

For the given question;

The volume of air inhale (and exhale) once = 0.475 liters

Number of breathing in 1 minutes = 18 times.

Thus, the volume of air inhaled in 1 minutes is 0.47×18 = 8.46 litres.

This can be written as;

1 minutes ------- > 8.46 litres of air.

For calculating in 8 hours that is 8×60 = 480 minutes, multiply the both side by 480 in above equation;

1× 480 minutes ------- >  480×8.46 litres of air.

480 minutes --------> 4060.8 litres of air.

Therefore. the volume of air in liters that might inhale (and exhale) in 8.00 hours is 4060.8 litres.

An architect is making a scale model of an office building he wishes to construct. The model is 9 inches tall. The actual office building he plans to construct will be 75 feet tall. a. What is the scale of the model? b. What scale factor did the architect use to build his model?

Answers

Using proportions, it is found that:

a. The scale of the model is of 9:900.

b. The scale factor used was of 100.

What is a proportion, and how it is related to scale problems?

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the context of a situation using operations such as multiplication and division to find the unit rates.

The concept of proportion is followed in scale problems, as scale is the proportion of the drawn distance by the actual distance, as follows:

Scale = Drawn distance : Actual distance.

For the building, in this problem, we have that:

The drawn height is of 9 inches.The actual height is of 75 feet = 900 inches.

Applying it's formula, the scale is given by:

9 : 900

The ratio between the actual height and the drawn height is the scale factor, hence:

Scale factor = 900/9 = 100.

Answers

The expression representing height of kite from ground is Height = sin 50° × 40.

The kite, person holding the string and ground from where height is to be measured will form right angled triangle. We can use the sine function to find the height of kite from the ground. Writing the trigonometric relation -

sin theta = perpendicular ÷ hypotenuse

Keep the values in mentioned trigonometric relation to find the expression -

sin 50 = height ÷ 40

Height = sin 50° × 40

Finding the height using formed equation -

Height = 0.77 × 40

Performing multiplication

Height = 30.64 meters

The CLT is frequently thought to hold for sample sizes equal to or larger than 30.The sample size and variability affect how accurate your statistics are.

During training, an athlete ran 250m/min. But then on the day of the race, he increased his average speed to 300m/min and finished the race one miute faster than he had during training. What distance was the race?

Answers

Answer:

6 m

Step-by-step explanation:

First I want you to understand that distance = speed × time.Consider:

speed= 250. 300.

minutes= let it be x. x-1

distance= 250× x. 300(x-1)

=250x. 300x-300

Since distance remains the same ,250x=300x-300

hence. -50x=-300.

x= 6

The length of the race was 1500 meters.

What is Speed?

Speed is defined as the rate of change of distance travelled per unit time.

Given is an athlete who ran at a speed of 250 m/min. However, on the day of the race, he increased his average speed to 300 m/min and finished the race one minute faster than he had during training.

Assume that the length of the race is (x) meters. Suppose that the runner takes (t) minutes to to complete the race in training. Therefore, we can write -

x = 250t

During the race -

x = 300(t - 1)

Equating both, we get -

250t = 300(t - 1)

250t = 300t - 300

300 = 50t

t = 6 min

Then, the length of the race will be -  

x = 250 x 6 = 1500 meters

Therefore, the length of the race was 1500 meters.

suppose a series system has three components c1, c2, and c3 with the probability that each component functions equal to 0.90, 0.99, and 0.95, respectively. what is the probability that the system operates? (4 decimals)

Answers

0.8465 is the probability that the system operates if the probability that each component functions equals to 0.90, 0.99, and 0.95 respectively.

As the components are in a series system, this means that all the components have to function in order for the system to operate, and the failure of any one of the components to function will result in the system not operating.

Therefore, the probability for the system to operate is the probability that all the components c1, c2, and c3 function together

The probability of multiple events occurring together can be found by multiplying the probabilities of each event by one another.

Therefore;

Probability = 0.90 × 0.99 × 0.95

Probability = 0.84645

Rounding it off to 4 decimals as follows;

Probability = 0.84645 = 0.8465

-x² - 2x + 48

Factorizing:

-1(x² + 2x - 48)

= -1[x² + 8x - 6x - 48]

= -1[x(x + 8) -6(x + 8)]

= -1(x + 8)(x - 6)

What is perimeter ?

The complete circumference of a shape is referred to as its perimeter. It is the length of any geometric shape with a two-dimensional boundary or outline. Depending on their proportions, multiple figures can have equal perimeters. Think of a triangle built of an L-length wire as an example. If the length of each side is the same, the same wire can be used to create a square. Look at the illustration below, which shows the bounds of a rectangular park.

Given that :The perimeter is 70[tex]cm^{2}[/tex]. The sides are 3x-1, 3x, 4x+ 1.

3x -1 + 3x + 4x + 1 = 70

10x = 70

x = 7
