Luke asserts that since the shape is constant, two circles are always isometric. he is wrong. No, an isometry keeps the size and shape intact.
Given that,
Luke asserts that since the shape is constant, two circles are always isometric.
We have to say is he accurate.
The answer is
No, an isometry keeps the size and shape intact.
Because a shape-preserving transformation (movement) in the plane or in space is called an isometric transformation (or isometry). The isometric transformations include translation, rotation, and combinations thereof, such as the glide, which combines a translation with a reflection.
Therefore, Luke asserts that since the shape is constant, two circles are always isometric. he is wrong. No, an isometry keeps the size and shape intact.

Since we are given a problem that says that Jake owns a bakery amd he makes 8.5 boxes of cupcakes in 15.5 hours, the question is how many cupcakes he makes in 1 hour .So the time taken is 15.5 and the number of cupcakes made in the 15.5 hours is 8.5. So 15 .5hours=8.5 cupcakes, now dividing both sides by 15.5, we get: 1 hour=8.5/15.5 =0.54 = 1 cupcake, therfore, it needs 1 hour to make 1 cupcake.

5. What is the range? Explain. (1 point)
The range of the given graph is [5, ∞).
Range.
Range refers the set of possible output values, and if we have the graph, then the set of all possible y values on the graph is defined as the range.
Given,
Here we have the graph.
Through the given graph we have to find the range of the line.
As per the definition of range, we have identified that the range take the value of y axis.
While we lookin into the given graph, we have identified that the starting point of the line is
=> (0, 5)
In this point 0 refers the x coordinate and 5 refers the y coordinate. So, the starting range is 5.
And the end of the line is not pointed.
So, we can consider that this line goes infinitely.

Canada computer charges 18.70/h plus 20.00 for a service call. the repairs person came to do maintenance on all of the school's computers. if the job took three and a half hours, what was the bill?
Using a linear equation to solve this problem, the charge for a 3.5 hour job is 85.45 dollar.
How much was the bill?To find how much was the bill, we need to write an equation or linear equation for this.
For every linear equation, it takes the form of y = mx + c.
Where m and c are the slope and intercepts of the straight line.
In this case, our linear equation can be written as
y = 18.70x + 20
where x = number of hours worked.
If the job took three and a half hour which is 3.5 hours, we can substitute this into the equation and solve.
y = 18.70(3.5) + 20
y = 85.45

jada sells b books and m magazine subscriptions to raise money for a choir trip. She earns $4 for each book and $3 for each magazine subscription she sells, and she earns a total of $96 toward the cost of her choir trip. The equation that models the situation is 4b + 3m = 96.
[tex]b = \frac{96-3m}{4}[/tex] and [tex]m = \frac{96-4b}{3}[/tex] for the equation that models.
Jada sells b books and m magazine subscriptions to raise money for a choir trip. She earns $4 for each book and $3 for each magazine subscription she sells, and she earns a total of $96 toward the cost of her choir trip.
Given that
1. Jada sells b books and m magazines
2. She earns $4 for each book and $3 for each magazine
3. Total amount she earned is $96
Given equation is
4b + 3m = 96
Solve 4b + 3m = 96 for b
Subtract 3m from both sides
4b + 3m - 3m = 96 - 3m
4b = 96 - 3m
Now divide both sides by 4
= [tex]b = \frac{96-3m}{4}[/tex]
So, the answer for b is [tex]\frac{96-3m}{4}[/tex]
Now, solve 4b + 3m = 96 for m
Subtract 4b from both sides
4b + 3m - 4b = 96 - 4b
= 3m = 96 - 4b
Now divide both sides by 3
= [tex]m = \frac{96-4b}{3}[/tex]
So, the answer for m is [tex]\frac{96-4b}{3}[/tex]
Hence the answer is [tex]b = \frac{96-3m}{4}[/tex] and [tex]m = \frac{96-4b}{3}[/tex] for the equation that models.

Given that Mr. Townsend needs to make 13 pairs of butterfly wings for costumes for a play. Each pair of wings is made with 3/4 yards of fabric. The fabric costs $8 per yard. The total cost of the fabric is $78.
What is the total cost?The total cost formula is used to get a total by combining the variable and fixed expenses of delivering commodities.
The step-by-step is given as follows:
1) Total cost (TC) = 3/4 (P) x 13
2) 1 pair of wings = 3/4 yard fabric
Recall that the price of 1 yard of fabric = $8
3) 1 pair of wings = $8 x 3/4 = $6

Spinner has 10 equally sized sections, one of which is blue and nine of which are yellow. The spinner is spun and, at the same time, a fair coin is tossed. What is the probability that the spinner lands on yellow and the coin toss is tails?
The probability that the spinner lands on yellow and the coin toss is tails is 9/10.
What is probability?
Probability shows the likelihood of an event happening. it can be calculated by dividing the number of outcomes of an event by the total number of possible outcomes or sample space. Probability is equal to '1' when the event is certain to occur. i.e P =1. It is less than '1' when it is not likely to occur. i.e P< 1
Probability P=no. outcomes/total no. of the possible outcomes
From the question;
No of blue=1
No of yellow=9
No. of total possible outcome=10
Therefore the probability that the spinner lands on yellow and the coin toss is tails P= 9/10.

3 9 8 hours. the tap of larger diameter takes 10 hours less than the smaller one to fill the tank separately. find the time in which each tap can separately fill the tank
The smaller tap take 25 hours to fill the tank and the larger tap take 10 hours to fill the tank.
How to calculate time taken to fill the tank for each tap?
Given,
Time taken for two tap together to fill the tank = [tex]9\frac{3}{8}[/tex] hours = [tex]\frac{75}{8}[/tex] hours
Time taken for smaller tap to fill the tank = x hours
Time taken for larger tap to fill the tank = x - 10 hours
So,
Tank filled by two tap together in 1 hour = [tex]\frac{8}{75}[/tex]
Tank filled by smaller tap in 1 hour = [tex]\frac{1}{x}[/tex]
Tank filled by larger tap in 1 hour = [tex]\frac{1}{x-10}[/tex]
Then, tank filled by two tap together is equal to tank filled by smaller tap and larger tap. So,
[tex]\frac{8}{75} = \frac{1}{x} + \frac{1}{x-10}[/tex]
[tex]\frac{8}{75} = \frac{x-10+x}{x(x-10)}[/tex]
[tex]\frac{8}{75} = \frac{2x-10}{x^{2}-10x}[/tex]
[tex]8x^{2}-80x = 150x - 750[/tex]
= [tex]8x^{2} - 230x + 750[/tex]
= [tex]2(4x^2 - 115x + 375)[/tex]
= [tex]4x^2 - 100x - 15x + 375[/tex]
= [tex](4x - 15) (x - 25)[/tex]
If, x = [tex]\frac{15}{4}[/tex] then x - 10 for larger tap equal to [tex]\frac{15}{4}[/tex] - 10 = [tex]- \frac{25}{4}[/tex] < 0 hours, so it is impossible.
Then, x must be 25. So, for larger thank is 25 - 10 = 15.
Smaller tap take 25 hours to fill the tank
Larger tap take 15 hours to fill the tank.
Thus, the smaller tap take 25 hours to fill the tank and the larger tap take 10 hours to fill the tank.

Since the two vector have opposite directions, their sum will be the difference of magnitudes:
r + s = 164 - 125 = 39And the direction is the same with the vector with greater magnitude, so it is south.
Answer:
Magnitude = 39 km
Direction = South
