Answer:
6 miles
Step-by-step explanation:
A mile is 1760 yards; and hour is 3600 (=2x1800) seconds.
So a yard per second is roughly two miles per hour (actually 1800/1760 x2 miles per hour, so the error is about 40 in 1800 or less than 1 in 40, 2.5%) and three yards per second is about 6 miles per hour. Upper bound of the estimate would be 6 + 2.5% = 6+0.15 = 6.15 mph.

Subtract the rational expression
Please show steps
Answer:
1/(x -2)
Step-by-step explanation:
You want the simplified form of the rational expression ...
[tex]\dfrac{1}{x-4}-\dfrac{2}{x^2-6x+8}[/tex]
SimplificationWe simplify this by combining terms over a common denominator, then cancelling any common factors from numerator and denominator.
[tex]\dfrac{1}{x-4}-\dfrac{2}{x^2-6x+8} = \dfrac{(x-2)}{(x-4)(x-2)}-\dfrac{2}{(x-4)(x-2)}\\\\\\=\dfrac{(x-2)-2}{(x-4)(x-2)}=\dfrac{x-4}{(x-4)(x-2)}=\boxed{\dfrac{1}{x-2}}[/tex]
Note that the domain still excludes x=4, in addition to the obvious exclusion of x=2.

Which is the best statement of the angle-angle similarity theorem?
A. When the preimage of a triangle is a dilation of the image, the triangles are similar.
When triangles have two pairs of corresponding angles that are congruent, the third pair of angles is also congruent.
B. When triangles have two pairs of corresponding angles that are congruent, those triangles are similar.
C. When the interior angles of a polygon sum to 180 degrees that polygon is a triangle.
The best statement of the angle-angle similarity theorem is (a) When the preimage of a triangle is a dilation of the image, the triangles are similar.
How to determine the similarity statement?The angle-angle similarity theorem is used in similar triangles; especially when a triangle is dilated (i.e. resized) to form another triangle
When triangles are dilated, the corresponding angles in both triangles (i.e. the image and the pre-image) are always equal
Hence, the best statement of the angle-angle similarity theorem is (a)

d. 95% of the students have a test score between
e. What percentage of the students scored less than a 792
f. What percentage of the students scored between a 55 and a 912
Answer:
Mean = 79
Step-by-step explanation:
99 + 60 + 82 + 78 + 93 + 71 + 68 + 86 + 80 + 95 + 72 + 64
Then divide by 12 because that's the total of numbers there are.

As the time went by the shadow got smaller untill it hit three pm and 4pm. The reason the box shadow did not change over the time period of 4pm and 7pm is because at night there is no chance of light hitting around the box because from this graph I can see that the sun was goung down by 3pm. In conclusion the graph below shows when the sun was up and when the sun went down.

he tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.
Cara’s Flower Arrangements
White 3 6 9 12 15
Yellow 5 10 15 20 25
Hector’s Flower Arrangements
White 4 8 12 16 20
Yellow 6 10 14 18 22
Part A
Are the numbers of white and yellow flowers in Cara’s arrangements proportional?
Which equation relates the number of white flowers, w, to the number of yellow flowers, y?
Yes; y=35w
Yes; y=53w
No; y=3w+5w
No; y=5+3w
Part B
Are the numbers of white and yellow flowers in Hector’s arrangements proportional?
Which equation relates the number of white flowers, h, to the number of yellow flowers, e?
Yes; e=32h
Yes; e=23h
No; e=h+2
No; e=h−2
Answer:
A.
1. no, y = 5 + 3w
B.
no, e = h + 2
Step-by-step explanation:
Using the principle of proportional relationship to model the two tables, we can infer that, the first first table is proportional while the second isn't.
Clara's arrangement :
White (w)Yellow (y)Testing if relationship is proportional :
y = kw5 = 3k
[tex] k = \frac{5}{3}[/tex]
Yes, the relationship is proportional [tex] y = \frac{5}{3}w[/tex]
Hector's arrangement :
White (h)Yellow (e)The number of yellow flowers surpasses the number of white flowers by a constant value of 2.
Hence, the relationship can be modeled thus ;
e = h + 2Therefore, the relationship is not proportional.

What is the slope of the line?
Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Tod hunter (1888) who wrote it as "y = mx + c".
Step-by-step explanation:
Steps for Graphing a Line With a Given Slope
Plot a point on the y-axis. (In the next lesson, Graphing with Slope Intercept Form, you will learn the exact point that needs to be plotted first. For right now, we are only focusing on slope.)Look at the numerator of the slope. Count the rise from the point that you plotted. If the slope is positive, count up and if the slope is negative, count down.
Look at the denominator of the slope. Count the run to the right.
Plot your point.
Repeat the above steps from your second point to plot a third point if you wish.
Draw a straight line through your points.
Answer: as you can see the line only on the 1

Every 14 days, Debbie’s dog eats 4 1/5 pounds of dog food. If Debbie’s dog eats the same amount of food each day, how many pounds does her dog eat per day?
The amount of food her dog eat per day would be; 0.33 pound.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that Debbie’s dog eats 21/5 pounds of dog food every 14 days. Debbie’s dog eats the same amount of food each day.
Therefore,
21/5 pounds of dog food = 14 day
one day = 14 / (21/5 ) pounds of dog food
One day = 14 x 5/ 21
= 10/3
Therefore, the amount of food her dog eat per day would be; 0.33 pound.

About 3.9 x 10^7 people live in California. About 1.3 x 10^6 live in Maine. About how many times more people live in California than live in Maine?
- 3 times as many
- 30 times as many
- 300 times as many
- 3 x 10^6 times as many
Divide the number of people in California (3.9x10^7) by the number of people in Maine (1.3x10^6)
(3.9x10^7) / (1.3x10^6) = 30
It takes Krys and Glen 1_4hour to walk a mile. This week Krys walked 9 miles and Glen walked 3 miles. How much longer did Krys walk than Glen?
Answer:
Krys walked 1 1/2 hours longer than Glen.
Step-by-step explanation:
Glen walked 3 miles
3 x 1/4 = 3/4
Krys walked 9 miles
9 x 1/4 = 9/4
9/4 - 3/4 = 6/4
6/4 = 1 2/4
