Answer:
3/2 and 2/3
Step-by-step explanation:
Scale Factor = Image / object
You can take either of the three sides so as far as it corresponds with the side of the other triangle
Let's take longest sides
= 15/10 = 3/2 That's scale Factor from Triangle PQR to STU
The second question is the reverse of the first one
= 10/15 = 2/3
The same applies to when you use the other sides of the triangles.

Determine the value of x
Answer:
I would think it is 8
Step-by-step explanation:
By assuming the triangles are equal to each other in a way that the larger triangle is the smaller triangle's length times 2. For example, one side of the smaller triangle is 11 so times 2 would be the larger triangle's side. So, by dividing 16 by two, you would get 8. Hope this helped and that I did it correctly!
An intercepted arc has a length of 19 yards. If the radius is 4 yards, find the measure of the central angle in radians and degrees.
The length of an arc is the distance between the endpoints of the arc.
The central angle is: [tex]\mathbf{4.75\ rad}[/tex] or [tex]\mathbf{272.16^o}[/tex]
The given parameters are:
[tex]\mathbf{l = 19yd}[/tex] --- length of the arc
[tex]\mathbf{r = 4}[/tex] -- radius of the circle
The length of an arc is calculated as:
[tex]\mathbf{l =r\theta}[/tex]
Divide both sides by r
[tex]\mathbf{\theta = \frac lr}[/tex]
Substitute known values
[tex]\mathbf{\theta = \frac{19}4}[/tex]
[tex]\mathbf{\theta = 4.75\ radians}[/tex]
Convert to degrees as follows:
[tex]\mathbf{\theta = 4.75 \times \frac{180}{\pi}}[/tex]
[tex]\mathbf{\theta = 4.75 \times \frac{180}{3.142}}[/tex]
[tex]\mathbf{\theta = 272.16^o}[/tex]
Hence, the central angle is: [tex]\mathbf{4.75\ rad}[/tex] or [tex]\mathbf{272.16^o}[/tex]

Answer:
C) 30
Step-by-step explanation:
As, angle 8 = 150°
So angle 6 = 30°
As, they are supplementry to each other
Now, Angle 5 + Angle 6 = 180°
So,as angle
So, Angle 5
Angle 5 + 30° = 180°
Angle 5 = 180° - 30°
Angle 5 = 150°
So therefore, Angle 5 = 150°

Mary buys 8 cupcakes for $6 and Pete buys 12 cupcakes for $9. Who got the better deal PER cupcake or did they spend the same amount per cupcake?
Answer:
Step-by-step explanation:
Mary spends 8*6=48 dollars
Pete spends 9*12=108
Mary got a better deal per cupcake
Answer:
They spent the same amount per cupcake ($1.33)
Step-by-step explanation:
To solve this, we need to find the unit rate of cost per cupcake. To do that, we divide 8 by 6 and divide 12 by 9. When we do that, we get 1.33 for both. That means they spent the same amount per cupcake ($1.33).
The length of an island is decreasing a rate of 16 inches per year. How many years will it take for the change in length of the island to be -364 inches? Answer value
Answer: 23 years
Step-by-step explanation:
From the question, we are informed that the length of an island is decreasing a rate of 16 inches per year. The number of years that it will take for the change in length of the island to be -364 inches would be gotten by dividing 364 by the rate of decrease every year which is 16 inches. Therefore, this would be:
= 364 / 16
= 22.75 years
= 23 years approximately

The Math Club is raising money so they can attend a local competition next month. They have already raised $125 and they are selling candy bars to raise the rest of the money needed. Each candy bar sells for $2.50.
Answer: 100 candy bars
Step-by-step explanation:
You did not include the question but judging by the progression I can assume that the question is along the lines of how many candy bars they will need to sell to reach their target.
You did not include the amount they have to raise as well so let us assume that number is $375.
Assuming they have to raise $375 and they have already raised $125, the amount left to be raised is:
= 375 - 125
= $250
With each candy bar selling at $2.50, the number of candy bars they will need to sell is:
= 250/ 2.50
= 100 candy bars
You should use this process to find the answer to your question.
