* A helicopter's altitude changes by – 28 ft in 3 s.
What is the average change in the helicopter's altitude
each second? Show your work.
Answer:
-9.33 ft per second
Step-by-step explanation:
To calculate this, you just have to divide -28 by 3. When doing this, it will give the change per second or for every 1 second.
-28/3 = -9.33
Therefore, the average change in the helicopter's altitude each second is -9.33 ft.
The highway mileage (mpg) for a sample of 8 different models of a car company can be found below. Find
the mean, median, mode, and standard deviation. Round to one decimal place as needed.
20, 22, 26, 27, 30, 31, 35, 35
Mean =
Median =
Mode =
Standard Deviation =
Mean = 28.3 , Median = 28.5, Mode = 35, Standard deviation = 5.2
(All of the above are rounded off to one decimal place)
How to find mean, median, mode ?
The given data are : 20, 22, 26, 27, 30, 31, 35, 35
We know that, mean = (sum of samples)/(no. of samples)
= (20+22+26+27+30+31+35+35)/8
= 226/8 = 28.25 = 28.3 (approx)
Here, median = (sum of 4th & 5th sample)/2
= (27+30)/2 = 57/2 = 28.5
Since 35 appears highest number of times, i.e. 2 times, then we can say that mode is equals to 35
What is the required standard deviation ?Standard deviation = √{(20-28.3)²+(22-28.3)²+(26-28.3)²+(27-28.3)²+(30-28.3)²+(31-28.3)²+(35-28.3)²+(35-28.3)²}/8
= √{68.89+39.69+5.29+1.69+2.89+7.29+44.89+44.89}/8
= √(215.52/8) = √(26.94) = 5.190 = 5.2 (approx)

The garden has an area of 28 square meters. The length of the garden is 7 meters.
What is the width of the garden?
Answer:
4
Step-by-step explanation:
Twenty Eight Divided By Seven Equals Four
l x w = area
7 x 4 = 28
what formula would you use to find the area of this figure?
Step-by-step explanation:
Find the area of a square or rectangle by multiplying the length times the width. This formula looks like l*w. If the length is 5 and the width is 2, the area is 10 square units. Calculate the area of a four-sided shape that is not a rectangle by multiplying the base (one of the sides) by the height.

Consider the line y = 7x-5.
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Answer:
[tex]\boxed {\sf Parallel: 7 }[/tex]
[tex]\boxed {\sf Perpendicular: -\frac{1}{7}}}[/tex]
Step-by-step explanation:
First, identify the slope.
We are given the line y=7x-5.
This is in slope intercept form or y=mx+b where m is the slope and b is the y-intercept. So, the coefficient to x, or 7 in this case, is the slope.
m=5Now, find the parallel and perpendicular slopes.
1. Parallel Slope
Parallel lines never intersect, so they have the same slope. A parallel line has a slope of 7.
2. Perpendicular Slope
Perpendicular slopes intersect to form right angles. They have negative reciprocal slopes.
Negate the slope: 7⇒ -7 Find the Reciprocal (flip the numerator and denominator: -7/1 ⇒ -1/7A parallel line has a slope of 7 and a perpendicular line has a slope of -1/7.
Answer:
I'll help
Step-by-step explanation:
Parallel lines have the same slope so it will be 7.
And perpendicular lines if you multiply them together they have to add up to -1,
So 7 you change it to its opposite which is 1 over 7 and yeah just

helpp please! i don't understand this
Answer:
Step-by-step explanation:
Remark
This is actually a six sided figure. That really doesn't matter, but it's interesting to observe. It goes a long way to explaining what is going on. The trick to exterior angles is that as long as the figure is convex ( a closed figure whose lines do not cross), the exterior angles add to 360.
Once you know that, then you know that this figure must have 6 exterior angles and no matter how they are made, their total is 360.
Equation
n + n + n + n + 90 + 90 = 360 Combine like terms.
Solution
4n + 180 = 360 Subtract 180
4n = 360 - 180
4n = 180 Divide both sides by 4
4n/4 = 180/4
n = 45

$4.25 to use towards his bill. How much money did Simon have after paying for
lunch?
Answer:
$4.05
How:
1. $15 + the extra $4.25 = $19.25
2. $3.25 + $11.95 for the meal = $15.20
3. $19.25 - $15.20 = $4.05
Simon had $4.05 left after paying for lunch.
