Use the equation to help explain how the width changes in relation to changes in the length. A. w = 40 − l; the width increases as the length decreases B. w = l − 40; the width increases as the length increases C. w = 40 − l; the width increases as the length increases D. w = l − 40; the width increases as the length decreases
Answers
Answer:
D. w = l − 40; the width increases as the length decreases
Step-by-step explanation:
The formula for the perimeter of a rectangle =
P = 2l + 2w
Where to find the Width, we make w the subject of the formula.
Hence:
P - 2l = 2w
w = P - 2l/2
From the question, P = 80
Hence,
w = 80 - 2l/2
w = 80/2 - 2l/2
w = 40 - l
The width of a rectangle is always the longer side ,hence:
D. w = l − 40; the width increases as the length decreases

heights of adults women have a mean of 63.6 in and a standard deviation of 2.5 indies chebyshevs theorem say about the percentage of women with heights between 58.6 and 68.6in
Answers
Answer:
Chebyshev's Theorem (Tchebysheff's Theorem) suggests that this percentage would be greater than [tex]75\%[/tex].
Step-by-step explanation:
Let [tex]Y[/tex] be a random variable with a mean of [tex]\mu[/tex] and a (finite) variance of [tex]\sigma[/tex]. By Chebyshev's Theorem, for any constant [tex]k[/tex] where [tex]k > 0[/tex]:
[tex]\displaystyle P\left(\left|Y -\mu\right| \le k\, \sigma\right) \ge 1 - \frac{1}{k^2}[/tex].
In this question, let [tex]Y[/tex] denote height (in inches.) Accordingly, [tex]\mu = 63.6[/tex] whereas [tex]\sigma = 2.5[/tex].
Note, that the interval of interest [tex](58.6,\, 68.6)[/tex] is centered at [tex]\mu = 63.6[/tex]. Besides, the difference between [tex]\mu[/tex] and either endpoints of this interval is equal to [tex]5.0[/tex], which is the same as [tex]2\, \sigma[/tex].
Rewrite the interval [tex](58.6,\, 68.6)[/tex] as [tex](63.6 - 2\times 2.5,\, 63.6 + 2 \times 2.5)[/tex].
For the height [tex]Y[/tex] of one such individual, [tex]Y \in (58.6,\, 68.6)[/tex] is equivalent to [tex]\left|Y - 63.6\right| < 2 \times 2.5[/tex]. With [tex]\mu = 63.6[/tex] whereas [tex]\sigma = 2.5[/tex], that expression is equivalent to [tex]\left|Y - \mu \right| < 2\, \sigma[/tex].
The percentage of individuals with a height in the interval [tex](58.6,\, 68.6)[/tex] would be equal to the probability [tex]P(\left|Y - \mu \right| < 2\, \sigma)[/tex].
Compare this expression to Chebyshev's Theorem. Notice that [tex]k = 2[/tex]. Therefore:
[tex]\displaystyle P\left(\left|Y -\mu\right| \le 2\, \sigma\right) \ge 1 - \frac{1}{2^2} = 0.75[/tex].
In other words, at least [tex]75\%[/tex] of the heights would be between [tex]58.6[/tex] inches and [tex]68.6[/tex] inches.
A map has a scale of 4 cm : 4 km. If
Union and Clayton are 8 km apart, then
they are how far apart on the map?
Answers
Answer:
If Union and Clayton are 8 km apart, it means they are 8 cm far apart on the map.
Step-by-step explanation:
Map scale = 4 cm : 4 km
Hence,
1 cm : 1 kmGiven that Union and Clayton are 8 km apart.
Since 1 km is scaled as 1 cm on the map.Therefore, if Union and Clayton are 8 km apart, it means they are 8 cm far apart on the map.

When a transversal intersects a
pair of parallel lines it will create
two pairs of alternate exterior
angles.
Ricky claims the angles within
each pair are congruent to each
other, but not congruent to
either angle in the other pair.
Answers
Answer:
Part A none
Part B drawn
Step-by-step explanation:
Suppose the transversal intersects a pair of parallel lines it creates two pairs of alternate exterior angles.
Now if we look at the first figure we find that the alternate exterior angle 1 and 4 are equal . Also 3 and 2 are equal.
But <1 and < 2 are not equal . They are supplementary angles. Their sum is equal to 180 degrees.
Similarly angles 3 and4 are supplementary angles.
This situation does not support Ricky's claim. So you will select none in part A.
Now in part B we see that angle 5 &8 are equal and 6 & 7 are congruent.
This refutes Ricky's claims and this can be proved mathematically.
Angles 5 & 6 are supplementary angles. Similarly 7 & 8 are supplementary therefore they cannot be equal as they are unequal and a transversal is drawn not a perpendicular.
The part A none and for part B drawn.
Suppose the transversal intersects a pair of parallel lines it creates two pairs of alternate exterior angles.
Now if we look at the first figure we find that the alternate exterior angle 1 and 4 are equal . Also 3 and 2 are equal.
What is the meaning of the supplementary angle?
Two angles are called supplementary when their measures add up to 180 degrees.
But <1 and < 2 are not equal because they are supplementary angles. and the sum is equal to 180 degrees.
Similarly angles 3 and 4 are supplementary angles.
This situation is not support Ricky's claim so select none in part A.
Now for part B we see that angle 5 &8 are equal and 6 & 7 are congruent.
This refutes Ricky's claims and this can be proved mathematically.
Angles 5 & 6 are supplementary angles. Similarly 7 & 8 are supplementary
Therefore they cannot be equal as they are unequal and a transversal is drawn not a perpendicular.
Therefore for the part A none and for part B drawn.

Which expression has the same value as 37.4 - 54.9?
Answers
Answer:
D
Step-by-step explanation:
In the original expression = 37.4 - 54.9 = -17.5
So, we have to solve all the equations but 1 of them has to equal to -17.5
A) -54.9 + (-37.4) = -92.3
Remove parentheses
= -54.9 - 37.4
Subtract the numbers
-92.3
B) 54.9 - 37.4 = 17.5
Since 54.9 is greater than 37.4 just subtract normally
4 14
5 4. 9 < ------- Line up the decimal points like this
- 3 7. 4 <--------- Subtract the decimals
-----------------
1 7 . 5 <---------- This is the final answer to B.
C) 37.4 - (- 54.9) = 92.3
Change the sign to addition
=37.4 + 54.9
Add the numbers normally
54.9
+ 37. 4
--------------
92.3
D) 37.4 + (-54.9) = -17.5
Change the sign to subtraction
= 37.4 - 54.9
Subtract them normally (but as you can see you are subtracting a smaller number from a larger number so heres a trick that you can use switch the equation by putting the larger number in first like this....)
54.9 - 37.4 = 17.5 (REMEMBER the answer is not 17.5 because the original equation of D is reversed 37.4 - 54.9 so in this case your answer should be
- 17.5)
37.4 - 54.9 = -17.5
Your final answer is D because it matches 37.4 - 54.9.
Hope this helps!

What is the speed (in miles per hour) of the train?
Answers
Answer:
50 miles per hour
Step-by-step explanation:
The speed can be found from a graph of distance versus time by looking at the slope of the graph. Here, the graph is a straight line, so the slope is constant. This means the speed is constant.
__
It can be convenient to determine the speed by looking at distance for times that are 1 time unit apart. Here, that could be the distances at t=0 and at t=1. We see in that hour, the train traveled from 100 miles to 150 miles away from the station. Its speed was 150 -100 = 50 miles per hour.

Answers
Answer:

The number of snow storms were in the city in the five-year period is 75.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, during a five-year period 24% of snowstorms in a certain city caused power outages.
Let the number of snow storms were in the city in the five-year period be s.
57 of the snow storms did not cause power outages.
So, the equation is
s -24% of s =57
s-0.24s=57
0.76s=57
s=57/0.76
s=75
Therefore, the number of snow storms were in the city in the five-year period is 75.

Which of these units would be best to measure the length of our classroom?
1. meters
2. centimeters
3. liters
4. kilometers
5. millimeters
Answers
Answer:
1. meters
Step-by-step explanation:
The smallest unit given in the choice is millimeters. Then comes the centimeters, then meters, and the kilometers.
Liters is used to measure the volume of a liquid. For example we get 1 liters of milk but not 1 kilometers of milk.
The kilometers has a 1000 meters and
1m= 100 cm
1cm = 10mm
The kilometers is quite a large space and usually long distances such as length between 2 towns is measured in kilometers.
The area of the room or length is usually measured in feet but since feet is not given here.
1 feet = 0.3048 m
so the most suitable selection would be meters.
The millimeters is very small. 1 cm has 10 mm. A foot consists of 30.48 cm.
So meters is used.
