What is the circumference of Circle O?
Answer:
[tex]14\pi[/tex]
Step-by-step explanation:
The formula for finding the circumference of a circle is 2 times pi times the radius.
Looking at the picture, we can see that the radius of the circle is 7 cm. Plugging that into the formula gives:
2*[tex]\pi[/tex]*7 = 14[tex]\pi[/tex]
Answer: 14π cm or 43.98 cm.
Step-by-step explanation: To find circumference, one must use the equation c = 2πr (c = circumference and r = radius). Plugging in the values, we get 2πr = 2*π*7 which = 14π or if you want it rounded: 43.98 cm.

Explain how to find the original and the new dimensions of an object when the scale changes. plz hurry
Answer:
Doing it again duhh
Step-by-step explanation:
Answer:
To find the original dimensions, write a proportion with the scale as the first ratio and the scale dimension compared to the actual dimension as the second ratio. Use cross products to solve. To find new dimensions, write a proportion with the new scale as the first ratio and the scale dimension compared to the actual dimension as the second ratio. Use cross products to solve.

Which statements accurately describe how to determine the y-intercept and the slope from the graph below?
On a coordinate plane, a line goes through points (0, negative 6) and (3, 0).
To find the y-intercept, begin at the origin and move horizontally to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction.

Step-by-step explanation:
Answer: Choice C
To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = (y2-y1)/(x2-x1)
============================================
Explanation:
The y intercept is where the graph crosses the vertical y axis. So that's why we move vertically from the origin to get to the graph.
The slope is calculated as the difference of y values over the difference in x values. We subtract in the same order for both. In other words,
slope = rise/run = (change in y)/(change in x)
Positive slope means the line goes uphill when you move from left to right. Negative slope means the line goes downhill when you move from left to right.
∠A and ∠B are vertical angles. ∠B is supplementary to ∠C. If ∠C measures 42°, how large is ∠A?
Answer:
138 degrees
Step-by-step explanation:
Since angles B and C are supplementary, that would mean they add up to 180. The problem tells us that angle C is 42 degrees, so that would mean that angle B is 138 degrees. We are also told that angles A and B are vertical, which would mean that they are congruent to each other. That leaves us with the answer that angle A is 138 degrees.

Kimi’s dog gives birth to a litter of 4 puppies per year, on average. The relationship between time and the expected total number of puppies is shown on the graph. Which other ordered pairs would fall on this line? Select all that apply.
(0, 0)
(2, 6)
(3, 12)
(4, 14)
Answer:
(0,0) and (3,12)
Step-by-step explanation:
The ordered pairs that would fall on the line are (0, 0), (1, 4), (2, 8), (3, 12), and (4, 16).
As shown in the graph,
x-axis represents the number of years
y-axis represents the number of puppies.
The slope of the line is 4, which means that for every 1 year that passes, the number of puppies increases by 4.
The y-intercept of the line is 0, which means that if there are 0 years, then there are 0 puppies.
The ordered pairs (2, 6) and (4, 14) do not fall on the line because they do not follow the slope of the line.
For example, in the case of (2, 6), the number of puppies should be 8, not 6.
Therefore, the only ordered pairs that would fall on the line are (0, 0), (1, 4), (3, 12), and (4, 16).

The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of students in seventh and eighth grade combined is 584; 5/8 of them are seventh graders and 3/8 of them are eighth graders. If 4/5 of the seventh graders participated in track-and-field day and 7/8 of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.
Answer:
584 is the total number of students in the school.
5/8 are in seventh grade and 3/8 are in eighth grade.
4/5 of the seventh graders participated in the track meet, so there were (4/5 · 5/8) · 584 students in the seventh grade participating in the track meet.
7/8 of the eighth graders participated, so there were (7/8 · 3/8) · 584 students in the eighth grade participating in the track meet.
So, all together, there were
(4/5 · 5/8) · 584 + (7/8 · 3/8) · 584 students from the school in the track meet.
Let's simplify as you asked:
(4/5 · 5/8) · 584 + (7/8 · 3/8) · 584 = [(4/5 · 5/8) + (7/8 · 3/8)] · 584 (distributive property - factoring)
= [20/40 + 21/64] · 584 (multiply fractions)
= (1/2 + 21/64) 584 (reduce the first fraction to lowest terms)
= (32/64 + 21/64) 584 (getting a common denominator)
= (53/64) 584 (combine/add the two fractions)
= 483.625 (multiply together)
All together, there were: 483.625 students in the meet.

Saba and Hena saved up Rs. 81.75 and Rs 45.25 respectively to buy a gift for
Mother’s Day. How much money in all have the sisters set aside for the gift?
Answer: $127.00
Step-by-step explanation:
Step 1: Line 81.75 + 45.25 up with 81.75 on top and 45.25 underneath.
Step 2: add the two 5’s (making 10) put the 0 underneath that and carry the one over to the left. ( 7+2+1 =10) then put your decimal point after the zero. repeat process (5+1+1=7) than add up 8+4 =12

The relationship between a distance in yards and the same distance in miles is described by the equation y=1760m. Find measurements in yards and miles for distances by completing the table.
(Second question) is there a proportional relationship between a measurement in yards and a measurement in miles for in the same distance? Explain why or why not
Answer: Question 1:
Distance Measure in miles | Distance measured in yards
---------------------------------------------------------------------------------
1 | 1760
---------------------------------------------------------------------------------
5 | 8800
---------------------------------------------------------------------------------
2 | 3520
---------------------------------------------------------------------------------
10 | 17600
---------------------------------------------------------------------------------
Question 2:
Yes, there is a proportional relationship between a measurement in yards and a measurement in miles, since a change in one variable leads to a direct change in the other variable, and there exists a constant ratio between them.
