Step-by-step explaunfere:
The circumference of a circle is the distance around the outside of the circle. The diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference.
1- C ≈ 50.27 in
2- C ≈ 31.42 in
3- A ≈ 201.06
4- A ≈ 314.16
5- C = 14π = 43.982 ≈ 44 inches
π (Pi) times the Radius squared: A = π r2
or, when you know the Diameter: A = (π/4) × D2
or, when you know the Circumference: A = C2 / 4π

Last year the Chess club had 30 members. This year the club has 24 members.
Please help asap
Answers
Last year the chess club had 30 members. This year the club has 24 members.
Last year, the chess club had 30 members. This year, the club has 24 members. Since this year had less than last year ( 30 > 24), the percent will be decreasing.
To find the percent decrease, you have to use the following formula.
[tex]\frac{Difference}{Original} \times 100[/tex]
Difference refers to the difference between the two numbers, 24 and 30. The difference between 24 and 30 is 6. Original refers to the original number, which is last year's amount of members in the chess group. Therefore, original = 30.
Substitute the numbers into the formula.
[tex]\frac{Difference}{Original} =\frac{6}{30} =0.2[/tex]
To convert the decimal to a fraction, multiply the decimal by 100.
[tex]0.2 \times 100 = 20 \%[/tex]
The answer is the number of chess members decreased by 20%.
____
Since I started off by identifying whether it was decreasing or increasing, I did the work a bit differently. When finding the difference, you would usually subtract 30 from 24, which results in -6. Above I used 6, but if you used -6, you would end up with a result of -20%, which means it decreased by 20%. They bot end up with the same result, but you don't always have to first identify whether it's decreasing or increasing.

Answer:
Decreasing
Step-by-step explanation:
The percentages are decreasing because one year the club had 30 members and the present year has 24 members that decreased by 6!

Which angle has a measure equal to the sum
of m_SQR and mzQRS?
O ZRSC
O LSRE
O ZDQS
O ZQSR
Answers
Answer:< RSC
Step-by-step explanation:
The angle has a measure equal to the sum of m <SQR and m <QRS is
m <RSC.
The correct option is A.
We have the information from which we can write
<SQR and < QRS are two interior angles of triangle QRS
Then, m<QSR = 180 - (sum of other 2 angles)
m<QSR = 180 - (m<SQR + m<QRS) (Angle sum property)
Also, m<RSC = 180 - m<QSR
Then <RSC = (m<SQR + m<QRS)
Thus, the ideal solution is A.

for a small party of 12 people, the caterer offered a choice of a steak dinner for $12:00 per or a chicken dinner for $10.50 the final cost for the meals was 138:00. how many of each was ordered?
Answers
Answer:
let the $12 dish be x and the other y
x + y = 12 <--- 1
12x + 10.50y= 138 <--- 2
multiply equation 1 by 12
so now we have
12x + 12y = 144
12x + 10.50y = 138
now subtract each one and that cancels out x
1.5y = 6
y = 4
now subsitute that into any equation
x + 4 = 12
x = 12 - 4
x = 8

Do these side lengths make a triangle?
6, 10, 15
Answers
Answer:
No.
Step-by-step explanation:
They do not create a triangle because if you follow the expression: a^2+b^2=c^2 it does not equal. Hope I helped :)
Answer:
a^2 + b^2 = c^2 - Pythagorean Theorem
6^2 + 10^2 = 15^2
36 + 100 = 225
136 doesn't equal 225
So, no, the sides lengths don't make a triangle.

Sally is making a scale drawing of her apartment.
• She drew a line measuring 1 1/2 inches to represent the 12-foot width of her living room.
• The length of her living room is 18 feet.
How long a line should Sally draw to represent the length of her living room?
A. 2 inches
B. 2 1/4 inches
C. 2 1/2 inches
D. 3 inches
Answers
We know that 1 1/2 is 12 foot
So we divide it by 2 so we know every 6 feet how long is it so we will get 0.75 for each 6 feet.
Now we divide 18ft by 3. We will have three sixs
Now multiple 0.75 by 3 = 2.25 which means the answer is B

Answer:
2 13/20
Step-by-step explanation:
we can split up 2.65 into a whole number and a decimal
2.65
= 2 + 0.65 (note that 0.65 = 65/100)
= 2 + 65/100
= 2 65/100 (we can see that both numerator and denominator are multiples of 5, hence we can try to simply by dividing both numerator and denominator by 5)
= 2 (65÷5) / (100÷5)
= 2 13/20 (answer)

Step-by-step explanation:
All sides of the triangle are equivalent to each other.
All three sides of the triangle equal 180 degrees total.
Since there are 3 sides, we divide 180 by 3 to find the measurement for all sides
180 ÷ 3 = 60
Q = 60 degrees
P = 60 degrees
R = 60 degrees
Check your work by adding all three sides together to equal 180:
60 + 60 + 60 = 180
180 = 180
