Kyle is buying a new car. The car can be driven 24.3 miles with one gallon of gas. The
gas tank can hold 15.3 gallons of gas.
Kyle wants to know how far he can travel on a full tank of
gas. Which method and
reasoning can Kyle use to find the distance he can travel in miles?
Answer:
im sure the answer is 371.79
Step-by-step explanation:
Answer:
Unitary method
Total distance = 371.79 miles
Step-by-step explanation:
We are given that Kyle is buying a new car.
The car driven in one gallon of a gas =24.3 miles
The gas tank holds=15.3 gallons
We have to find the method and reasoning can Kyle use to find the distance he can travel in miles.
We have to find the distance travel in 15.3 gallons of a gas
So , we are using unitary method .
Unitary method : When we want to find more than one units with the help of one unit by multiplying
Because we are finding in 15. 3 gallons which is more than one and we are given that in 1 gallon of a gas car travel 24. 3 miles
Total distance =
Hence, the distance Kyle can travel in 15.3 gallons of gas=371.79 miles

Find the equation of a line that contains the points (6, -7) and (8,5). Write the equation in slope-intercept form.
Answer:
y = 6x - 43
Step-by-step explanation:
(6, -7) and (8,5)
m=(y2-y1)/(x2-x1)
m=(5 + 7)/(8 - 6)
m= 12/2
m = 6
y - y1 = m(x - x1)
y + 7 = 6(x - 6)
y + 7 = 6x - 36
y = 6x - 43

Use rounding to estimate the product of 1249 and 1194. Round both numbers to the nearest hundred to find your answer.
Answer:
1,440,000
Step-by-step explanation:
1249 is rounded to 1200 because 49 is less than half of 100.
1194 is rounded to 1200 because 94 is more than half of 100.
1200 x 1200 = 1,440,000

A garden is shaped like a rectangle whose perimeter is 260 ft. The length is 9 times as long as the width. Find the length and the width
Answer:
The length is 117 ft and the width is 13 ft.
Step-by-step explanation:
From the question itself, we can write down the following equations...
(Let "P" be the perimeter of the rectangle, Let "L" be the length, and let "W" be the width, then...)
L = 9W
and
P = 2L + 2W
Now, we substatute the "L" value and get...
P = 2L + 2W
260 = 2(9W) + 2W
260 = 20W
W = 260 / 20
W = 13
Since we know the width we can now find the length by using the very first formula...
L = 9W
L = 9(13)
L = 117
Therefore, the length is 117 ft and the width is 13 ft.

Different dealers may sell the same car for different prices. The sale prices for a particular car are normally distributed with a mean and standard deviation of 26 thousand dollars and 2 thousand dollars, respectively. Suppose we select one of these cars at random. Let X= the sale price (in thousands of dollars) for the selected car. Find P(X>25), left parenthesis, X, is greater than, 25, right parenthesis. You may round your answer to two decimal places.
Answer:
P(X > 25) = 0.69
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The sale prices for a particular car are normally distributed with a mean and standard deviation of 26 thousand dollars and 2 thousand dollars, respectively.
This means that [tex]\mu = 26, \sigma = 2[/tex]
Find P(X>25)
This is 1 subtracted by the pvalue of Z when X = 25. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{25 - 26}{2}[/tex]
[tex]Z = -0.5[/tex]
[tex]Z = -0.5[/tex] has a pvalue of 0.31
1 - 0.31 = 0.69.
So
P(X > 25) = 0.69

The manager of a rug shop bought some rugs for $16 each. He was able to sell all but 6 of them for $22 each, making a profit of $168. How many rugs were originally bought?
Answer:
the total of rugs is 8
Step-by-step explanation:
6 for $22 means he sold 6 of them and made $132
then take 168 - 132 and we get 36
the rest are 16 each so 2 rugs was the maximum.

Another formula:
L2+W2 (length x 2 + width x 2)
Answer:
C
Step-by-step explanation:
Perimeter of a rectangle = 2(l + b)
= 2( 9 + 13)
= 2(22)
