Find his speed
Find his gas mileage
Find the unit price he paid for gas.

Answers

Answer:

Step-by-step explanation:

Mr. Anderson drove 168 miles in 3 1/2 hours: d1 = 168 mi  

t1 = 3 1/2 hr

t1 = 3.5 hr

v1 = the first rate

v1 = d1/t1

v1 = 168/3.5

v1 = 48 mph

He then drove 2 1/4 hours at a rate of 5 miles an hour faster than the first rate:

t2 = 2 1/4 hr

t2 = 2.25 hr

v2 = v1 + 5

v2 = 48 + 5

v2 = 53 mph

d2 = the distance

d2 = v2*t2

d2 = 53*2.25

d2 = 119.25 mi

during the total time 3 1/2 + 2 1/4 = 5 3/4 hr Mr. Anderson drove:

d1 + d2 = 168 + 119.25 = 287.25 mi.

Ariana buys an ant farm from a store near her home. The ant farm's price is $12 and the sales tax is 7%. What is the total price of the ant farm? 100 points

Answers

Answer: The total price for ant farm is $12.84

Step-by-step explanation:

The price of ant farm =  $ 12

The sales tax on the  price = 7%

Noe, 7% of $12 =

⇒The tax amount on the price = $0.84

So, the Taxed amount = The original price  + Tax

$ 12 + $0.84  = $12.84

Hence the total price for ant farm is $12.84

Which of the following is most affected by the lower score?

A.) the mean and median
B.) the median
C.) the mean
D.) the mode​

Answers

Answer:

C

Step-by-step explanation:

The mean of a set of values is the average of all of them. The median is just the center most value when you arrange the values in order from least to greatest, or the average of the most central two if there is an even number of values. The mode is simply the value that shows up the most. The single, low outlier does not affect the median and mode almost at all, and only has a large influence on the mean, since it brings down the average. Therefore, the correct answer is choice C. Hope this helps!

Answer:

The mean... the median is in the middle, it won't change, the mode is the most repetitive number and it won't change neither... so the mean will be the most affected.

Answers

Answer:

x = 58°

Step-by-step explanation:

First, we need to find the green angle on the bottom left of the triangle.

We know that straight lines are supplementary, or equal 180 degrees, so we can say that 114° + a (a variable representing the measure of the angle) = 180°.

Equation:

114 + a = 180

Solve:

114 + a = 180

-114         -114

a = 66

Therefore, the value of the green angle is 66 degrees.

Now, we need to find the value of angle x.

We know that the sum of the angles in a triangle is 180 degrees.

So, 56° + 66° + x = 180°

Equation:

56 + 66 + x = 180

Add:

56 + 66 + x = 180

122 + x = 180

Subtract:

122 + x = 180

-122        -122

x = 58

Therefore, x is 58 degrees.

Answer:

58

Step-by-step explanation:

An exterior  angle is equal to the two remote interior angles. It would be easier to understand that just by adding the numbers in an equation.

Exterior angle = 114

Remote interior angles = x and 56

exterior angle = sum of x and 56 which are the two remote interior angles.

x + 56 = 114          Subtract 56 from both sides.

x+56-56=114-56

x = 58

factory makes car batteries. The probability that a battery is defective is 1/14. If 400 batteries are tested, about how many are expected to be defective?
A) 14
B) 371
C) 29
D)35

Answers

Since it is 1 out of 14, take 400 and divide it by 14 (400/14) which would give 28.57142857... . So round to the nearest whole number = 29. SO THE ANSWER IS “C, 29”

The required number of defective batteries is 29 out of 400 batteries tested. Option C. is correct.

The probability that a battery is defective is 1/14. The probability that a battery is defective is 1/14. If 400 batteries are tested, how many are expected to be defective s to be determined?

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events. it can be denoted as,
Probability = number of favorable outcomes / total sample space


The probability that a battery is defective given by,
P(D) = 1/14 = 0.072 or 7.2%
400 batteries are tested while multiplying the defective percentage to the number of batteries it gives the defective number of batteries


Number of defective batteries,
= 400 * 7.2%
= 400 * 7.2/100
=≈ 29

Thus, the required number of defective batteries is 29 out of 400 batteries tested. Option C. is correct.

A cleaning company charges x dollars per hour to clean floors and y dollars per hour to clean the rest of the house
-when the company spends 2 hours to clean floors and 3 hours to clean the rest of a house,the total is $84.
-when the company spends 1 hour to clean floors and 4 hours to clean the rest of a house,the total is $87

Which ordered pair represents the hourly charges to clean floor and to clean the rest of the house?

A.(12,20)
B.(15,18)
C.(20,12)
D.(18,15)

Answers

Answer:

(15,18)

Step-by-step explanation:

write two equations with the information provided.

2x + 3y = 84

x + 4y = 87

use the property of substitution to answer.

x + 4y = 87,   x = 87 - 4y

2(87 - 4y) + 3y = 84

174 - 8y + 3y = 84

174 - 84 = 8y - 3y

90 = 5y

90/5 = y

y = 18

Add the value of Y to an original equation. Solve for X

2x + 3(18) = 84

2x + 54 = 84

2x = 84 - 54

2x = 30

x = 30/2

x = 15

a sector with a radius of 15 cm has a central angle measure of 8π/5 what is the area of the sector

Answers

Answer:

area of the sector = 360π cm²

Step-by-step explanation:

To calculate the area of the sector, we will follow the steps below;

First write down the formula for calculating the area of a sector.

If angle Ф is measured in degree, then

area of sector = Ф/360   × πr²

but if angle Ф is measured in radians, then

area of sector = 1/2 × r² × Ф

In this case the angle is measured in radiance, hence we will use the second formula

From the question given, radius = 15 cm  and angle Ф = 8π/5

area of sector = 1/2 × r² × Ф  

                         =1/2 × 15² ×  8π/5

                         =1/2 ×225 × 8π/5

                          =360π cm²

area of the sector = 360π cm²

Which of the following side lengths can form a triangle?

23, 28, and 55

24, 24, and 47

15, 30, and 45

8, 17, and 25

Answers

Answer:  24, 24, 47

Step-by-step explanation:

In order to form a triangle, the sum of two sides must be GREATER than the third side for all combinations.

a + b > c       &       a + c > b        &        b + c > a

23 + 28 = 51 which is NOT greater than 55

15 + 30 = 45 which is NOT greater than  45

8 + 17 = 25 which is NOT greater than 25

24 + 24 > 47      &        24 + 47 > 24       &       24 + 24 > 27

all combinations are true so these side lengths can form a triangle
