I’d ABCD is dilated by a scale factor of 2 about point E, which of the following is true about line segment E’F’
Answers
Answer:
Line Segment EF passes through the center of the dilatation
Step-by-step explanation:
I just know...
Option (4) will be the correct option.
Given in the question,
ABCD is dilated by a scale factor of 2 about point E.A'B'C'D' is the dilated figure.Option (1). E'F' is perpendicular to EF.
Since, center of dilation of ABCD is at E, E' will coincide point E.
Therefore, EF and E'F' can't be perpendicular.
Option (2). E'F' is parallel to EF.
Since, center of dilation of ABCD is at E, point E' will coincide point E.
Therefore, E'F' can't be parallel.
Option (3). E'F' intersects with point B'.
Since, center of dilation of ABCD is at E, EF will lie on E'F'.
Therefore, E'F' cant intersect point B'.
Option (4). E'F' passes through center of dilation.
Since, center of dilation of ABCD is at E, therefore, E'F' will pass through the center of dilation E.
Therefore, Option (4) is the correct option.

You need to make at least 360 wraps for a party. You can make 9 wraps per minute.
How long will it take you to make the number of wraps you need?
In two or more complete sentences write and solve an inequality for the situation and explain how you will solve the inequality.
Answers
Answer:
40 minutes
Step-by-step explanation:
What the person above/below me is saying, is you have to divide 360 and 9, to find x! X=40, 360/9=40! That's what they mean. I hope this helped you understand their answer!
It will take 40 minutes for me to make the 360 wraps that I need.
9x ≥ 360 ⇒ x ≥ 40
Step-by-step explanation:
I have to make at least 360 wraps for a party.
I can make 9 wraps per minute.
So, it will take minutes for me to make the 360 wraps that I need.
If I work for x minutes to make wraps, then I will be able to make 9x wraps.
So, the inequality that models the given condition is
9x ≥ 360
⇒ x ≥ 40 {Dividing both sides by 9}
Therefore, I need to work at least 40 minutes to reach my goal. (Answer)

How many milliliters are in 3 gallons?
Label your answer in mL.
Answers
Answer:
11355mL
Step-by-step explanation:
It gives you how many milliliters are in one gallon. From there it gives extra information that isn't needed so you skip it and go to the question which is the amount of mL in 3 gallons. So you take the amount from the first sentence (3,785 mL) and multiply it by the amount that they ask in th equestion (3 gal) .

Determine the resultant of the given vectors by component method. E = 23 km , 11 degrees N of E N = 25 km, 24 degrees E of N G = 19 km, 18 degrees S of W R = 27 km, 58 degrees W of N.
Answers
Answer:
The resultant of the given vectors by component method is [tex]\vec U = -8.222\,\hat{i}+35.664\,\hat{j}\,\,\,[km][/tex].
Step-by-step explanation:
First we define each vector by applying using rectangular form:
1) [tex]\|\vec E\| = 23\,km[/tex], 11º north of east.
[tex]\vec E = 23\,km\cdot (\cos 11^{\circ}\,\hat{i}+\sin 11^{\circ}\,\hat{j})[/tex] (Eq. 1)
2) [tex]\|\vec N\| = 25\,km[/tex], 24º east of north.
[tex]\vec N = 25\,km\cdot (\sin 24^{\circ}\,\hat{i}+\cos 24^{\circ}\,\hat{j})[/tex] (Eq. 2)
3) [tex]\|\vec G\| = 19\,km[/tex], 18º south of west.
[tex]\vec G = 19\,km\cdot (-\cos 18^{\circ}\,\hat{i}-\sin 18^{\circ}\,\hat{j})[/tex] (Eq. 3)
4) [tex]\|\vec R\| = 27\,km[/tex], 58º west of north.
[tex]\vec R = 27\,km\cdot (-\sin 58^{\circ}\,\hat{i}+\cos 58^{\circ}\,\hat{j})[/tex] (Eq. 4)
The resultant of given vectors is determined by vector sum, that is:
[tex]\vec U = \vec E + \vec N + \vec G + \vec R[/tex] (Eq. 5)
[tex]\vec U = 23\,km\cdot (\cos 11^{\circ}\,\hat{i}+\sin 11^{\circ}\,\hat{j})+25\,km \cdot (\sin 24^{\circ}\,\hat{i}+\cos 24^{\circ}\,\hat{j})+19\,km\cdot (-\cos 18^{\circ}\,\hat{i}-\sin 18^{\circ}\,\hat{j})+27\,km\cdot (-\sin 58^{\circ}\,\hat{i}+\cos 58^{\circ}\,\hat{j})[/tex]
[tex]\vec U = (23\,km\cdot \cos 11^{\circ}+25\,km\cdot \sin 24^{\circ}-19\,km\cdot \cos 18^{\circ}-27\,km\cdot \sin 58^{\circ})\,\hat{i}+(23\,km\cdot \sin 11^{\circ}+25\,km\cdot \cos 24^{\circ}-19\,km\cdot \sin 18^{\circ}+27\,km\cdot \cos 58^{\circ})\,\hat{j}[/tex]
[tex]\vec U = -8.222\,\hat{i}+35.664\,\hat{j}\,\,\,[km][/tex]
The resultant of the given vectors by component method is [tex]\vec U = -8.222\,\hat{i}+35.664\,\hat{j}\,\,\,[km][/tex].

When 12 of the bowls each had 8 more grapes added to them, the mean (average) number of grapes per bowl increased by 6.How many bowls of grapes are on the table?
Answers
Answer:
There are 16 bowls
Step-by-step explanation:
Number of bowls = x
Total grapes added = 12 x 8 = 96
The average increased by 6
So 96/6 = 16
There were 16 bowls of grapes on the table
OR
12 x 8 = 96
96/6=16

24) What is the equation for the table below?

First of all, you need to find the slopes of each. To do this, we need to take 2 points from each and plug them into y2 -y1/ x2 - x1.
For the graph we will take the points given (0,5) (4,0)
0 - 5 / 4 -0 = -5/4 = your slope for the graph
For the table, we will take the first three points. (-1,-1) (0,3) (1,7)
7 - 3 / 1 - 0 = 4 / 1 = 4
3 - - 1 / 0 - - 1 = 4 / 1 = 4
Therefore, the slope of the table is 4.
Now, for the y-intercepts.
These are normal be the points (0, y)
For the graph this would be (0,5) and for the table it would be (0,3)
Slope - intercept form = y = mx + b, where m is the slope and b is the y-intercept form.
Soo,
For the graph, it would be;
Y = -5/4x + 5
And for the table, it would be;
Y = 4x + 3

A cheetah runs at an average speed of 50 mph between two jungles that are 150 miles apart. An antelope runs at an average speed of 30 mph, a lion runs at an average speed of 25 mph, and an elephant runs at an average speed of 15 mph.
How long does it take each animal to run to the second jungle?
Answers
Answer:
cheetah, 3 hours antelope, 5 lion, 6 elephant, 10
Step-by-step explanation:
The time taken by each animal to reach another jungle are:
Cheetah = 3 hours
Antelope = 5 hours
Lion = 6 hours
Elephant = 10 hours
What is speed?Speed is a scalar quantity that refers to how fast an object is moving.
Given are the speeds of different animals,
Cheetah = 50 mph
Antelope = 30 mph
Lion = 25 mph
Elephant = 15 mph
Speed = distance/time.
Time = distance/speed
Distance = 150 miles
Time taken by each :
Cheetah = 150/50 = 3 hours
Antelope = 150/30 = 5 hours
Lion = 150/25 = 6 hours
Elephant = 150/15 = 10 hours
Hence, The time taken by each animal to reach another jungle are:
Cheetah = 3 hours
Antelope = 5 hours
Lion = 6 hours
Elephant = 10 hours
