6. One of the transformations above was a dilation by a scale factor of k. The scale factor is the multiplicative amount that the picture has been enlarged. To calculate it, divide any length on B by the corresponding length on A. Use your ruler to make these measurements and then calculate the scale factor of the dilation. Round to the nearest tenth.
Answers
Answer:
well it is b
Step-by-step explanation:
well I tried my best
When a figure or a shape is dilated, the size of its image will either be enlarged or compressed.
The scale of dilation from A to B is 1.5
See attachment for the image that completes the question.
Using a ruler, we have the following measurements
[tex]\mathbf{A = 1\ inch}[/tex]
[tex]\mathbf{B = 1.5\ inches}[/tex]
The scale factor (k) from A to B is:
[tex]\mathbf{k = \frac BA}[/tex]
This gives
[tex]\mathbf{k = \frac {1.5\ inches}{1\ inch}}[/tex]
[tex]\mathbf{k = \frac {1.5}{1}}[/tex]
[tex]\mathbf{k = 1.5}[/tex]
Hence, the scale factor (k) from A to B is 1.5

Solve for x and/or y:
Answers
Answer:
C) x=35
Step-by-step explanation:
First, we know that the total amount of degrees in a rotation is 360. As the picture tells us, the opposite angles will be exactly the same. Taking this information, we can have the following equation:
4x + 2(3x+5) = 360
By now using our linear equation skills, we get:
10x+10=360
10x=350
x=35
The degree amount of x for c) is 35 degrees.
C. Since the angles form a linear pair, their sum equals 180.
So, 2x + 3x + 5 = 180
x=35
D. Since the angles are verticle, they equal each other.
So, 3x + 5 = 5x -57
x=31

A public swimming pool that holds 45,000 gallons of water is going to be drained for maintenance at a rate of 100 gallons per minute. The amount of water, w (in gallons), in the pool after t minutes is given by the function w = 45,000 – 100t. How many minutes will it take to empty the pool?
Answers
Answer:
450 minutes
Step-by-step explanation:
Given
w = 45000 - 100t
Required
Determine how long it'll take to empty the pool
Being empty means there's no water in the pool.
So, we have to set w to 0 to get the value of t
i.e w = 0
Substitute 0 for w in w = 45000 - 100t
0 = 45000 - 100t
Collect Like Terms
100t = 45000
Divide through by 100.
t = 450
Hence, it'll take 450 minutes to empty the pool

Comment on supplementary angles
Angles that form a linear pair are supplementary. Angles do not have to form a linear pair to be supplementary. They merely have to have a sum of 180°. Here, the supplementary angles of interest do form a linear pair, so finding the other angle of the pair means only finding the other point that names the line being formed by the pair.

In a collection of coins, the number of quarters is one-third the number of pennies. The number of quarters is Q. The number of pennies is P. What is the correct formula relating Q to P
Answers
Answer:
Q = P/3
Step-by-step explanation:
Let the number of quarters be Q
Let the number of pennies be P
If the number of quarters is one-third the number of pennies, this can be expressed as;
Number of quarter = 1/3 of pennies
Q = 1/3 of P
Of means multiplication
The expression becomes;
Q = 1/3 × P
Q = P/3
Hence the formula relating Q to P is
Q = P/3
