Answer:
A total of 18 gallons of more gas
Step-by-step explanation:
7 gallons = 210 miles
750-210= 540
210*2 =420 miles 7*2=14 gallons
210/2= 105 7/2=3.5 gallons
525 miles 17.5 miles
210/14= 15 7/14=.5 gallons
540 miles 18 gallons
Jake plans to make and sell wooden birdhouses. He plans to sell each birdhouse for $50, his income can be found using the equation I(x) = 50x, where x is the number of birdhouses he sells. It costs him $10 in materials for each birdhouse, so his expenses can be found using the equation E(x) = 10x. Use function operations to find an equation for his profit, P(x), and find his profit if he sells 20 birdhouses.

A mole starts out in its burrow 5.1 feet below the surface of the ground. It digs straight up at a rate of 0.4 feet per minute.
How long does it take for the mole to reach a depth of -3.7 feet?
Enter your answer as a decimal in the box.
The mole approximately 3.5 minutes to reach a depth of -3.7 feet.
To determine how long it takes for the mole to reach a depth of -3.7 feet, we need to calculate the time it takes to cover the distance between its starting point and the target depth.
The mole is digging straight up at a rate of 0.4 feet per minute.
Since the target depth is negative, we can consider it as a negative displacement.
The distance the mole needs to travel can be calculated as follows:
Distance = Target depth - Starting depth
Distance = -3.7 feet - (-5.1 feet)
Distance = -3.7 feet + 5.1 feet
Distance = 1.4 feet
Now, we can calculate the time it takes for the mole to cover this distance using the formula:
Time = Distance / Speed
Time = 1.4 feet / 0.4 feet per minute
Time = 3.5 minutes
Therefore, the mole approximately 3.5 minutes to reach a depth of -3.7 feet.

The radicals is the name of the sign we use in roots. The numerator is the power of the exponential, and the denominator is the power of the root.
So we take the radical:
√((-4)^2/7)
And move the denominator to the place where we list the root's power:
7√((-4)2)

How tall is the building?
Answer:
17.3 ft
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
10^2 + h^2 = 20^2
100 + h^2 =400
Subtract 100 from each side
h^2 = 400-100
h^2 = 300
Taking the square root of each side
sqrt(h^2) = sqrt(300)
h = 17.32050808
Rounding to the nearest tenth
h = 17.3 ft

Carl calculates the z-score corresponding to the weight 255 oz. = Using the table (column.00), Carl sees the area associated with this z-score is O. Carl rounds this value to the nearest hundredth or 0. Now, Carl decides to find the percent associated with boxes less than 255 oz. so he rounds to hundredths and subtracts 0.50 -0. %. Unlimited Attempts Remain
Answer:2.07 is the answer as of e.2020
Step-by-Step: Mean = 270 Standard deviation = 10 x = 255 Formula for z-score, z = (x - mean)/SD z = (255 - 270) / 10 => z = -15 / 10 => z = -1.5 So by referring to z-table, -1.5 correlates to 0.0668 that implies to 0.07 So 7% of the boxes of Apples weight less than 255oz. The percentage of boxes is in the range of 255 oz and 270 oz, Now calculating the requiring percentage 50% - 7% = 43%

A dog on a 5-foot leash runs around in one full circle while its owner stands still. Which is closest to the distance the dog went?
The distance closest to the distance the dog went is 31.42 ft
Since the dog moves around in one full circle, the distance the dog moves is the circumference of a circle.
Circumference of a circle
The circumference of a circle C = 2πr where r = radius of circle.
Now r = length of leash = 5 foot
So, substituting r into the equation, we have
C = 2πr
C = 2π × 5 ft
C = 10π ft
C = 10 × 3.142 ft
C = 31.42 ft
So, the distance closest to the distance the dog went is 31.42 ft

2 box plots. The number line goes from 175 to 450. For resort A, the whiskers range from 175 to 375, and the box ranges from 250 to 300. A line divides the box at 375. For Resort B, the whiskers range from 200 to 400, and the box ranges from 300 to 375. A line divides the box at 325. Kevin wanted to go snowboarding for his vacation. He looked up annual snowfall of both resorts over a ten-year period to determine which resort would have the better snowfall. Compare the two box plots and use the drop-down menus to determine where Kevin should plan to go for vacation. What is the approximate median snowfall at Resort A? What is the approximate median snowfall at Resort B?.
Box plot 5 important descriptive measures about data that they represent.
The median snowfall for Resort B is greater than the median for Resort A
The interquartile range has higher values for Resort A than for Resort B.
Resort B has more snowfall overall than Resort A does.
How does a boxplot show the data points?
A box plot has 5 data descriptions.
The leftmost whisker shows the minimum value in the data.
The rightmost whisker shows the maximum value in the data.
The leftmost line in the box shows the first quartile.
The middle line shows the median, also called the second quartile.
The last line of the box shows the third quartile.
How to find the interquartile range?IQR(interquartile range) is the difference between the third and first quartile.
Inferring the information each box plot describe, we get:
Case 1: For resort A:
Wisker's minimum value = minimum value for resort A = 175
Maximum value = 375
Box's minimum value = First quartile = 250
Box's maximum value = Third quartile = 300
First quartile = 250 < Median = Second quartile < 300 = third quartile
Thus, 250 < Median for resort A < 300
IQR = Third quartile - first quartile = 300 - 250 = 50
Range of values = Max - min = 375 - 175 = 200
Case 2: For resort B:
Wisker's minimum value = minimum value for resort B = 200
Maximum value = 400
Box's minimum value = First quartile = 300
Box's maximum value = Third quartile = 325
First quartile = 300 < Median = Second quartile < 375 = third quartile
Thus, 300 < Median for resort B < 375
IQR = Third quartile - first quartile = 325 - 300 = 25
Range of values= Max - min = 400 - 200
Thus, it is visible that:
Median for resort A < 300 < Median for resort B
or
Median for resort A < Median for resort B.
and
IQR for resort A = 50 > IQR for resort B = 25
and
Both have the same variation as both ranges are the same, which is the interval of values assumed for both resorts.
Hence, Minimum, maximum, first, and third quartile all are smaller for resort A, thus, Resort B has more snowfall overall than Resort A does.

can 3 meters and 2 km be expresses as a ratio.
Answer:
yes, you can just write it as 3m : 2km
Step-by-step explanation:
I don't know if this is completely right, but I know you can also turn 3m into km by multiplying it by 1000, (because there are 1000 m in every km) and then solve because 3000km/2km = 1500km
So to solve would be 1500 km. I hope the first answer is right though. Did I help? Let me know in the comments

Answer:
the answer is written below
Step-by-step explanation:
Let side of Inner square be S and side of Outer side be mS.
Area of Inner Square = S**2
Area of Outer Square = (mS)**2
The ratio of area of Inner Square and Outer Square is 1:m**2
i.e. Area of Outer Square will be m**2 times Area of Inner Square.
