Answer:
So the formula of area of the circle A=πr2. The answer is 153.86.
Step-by-step explanation:
You first divide 14/2=7 then do 7^2 which equals 49 lastly multiplying 3.14 X 49. So how is the radius 7 because half of a diameter is a radius.Therfore the answer is 153.86.

Angles CBO and CAO are congruent
Applying the inscribed angle theorems, the true statements regarding the given diagram are: B. m∠BCA = 25° C. m∠BOA = 50°
What is the Inscribed Angle Theorems?The inscribed angle theorems state that:
Measure of intercepted arc = 1/2(measure of inscribed angle)Measure of intercepted arc = measure of central angle.∠BCA is an inscribed angle.
m(AB) is the intercepted arc = 50°
∠BOA is the central angle
m∠BCA = 1/2(m(AB) = 1/2(50) = 25°
m∠BOA = m(AB) = 50°
The true statements are:
m∠BCA = 25°
m∠BOA = 50°

Marcos invited 33 guests to his party. So far, 8 guests have replied "will attend" and 9 guests have replied "will not attend". How many guests (g) still need to reply?
Answer:
16 people haven't replied
Step-by-step explanation:
Add 9 + 8 = 17 and subtract 33 - 17 = 16
If this helps
The guests (g) still need to reply are 16.
What is arithmetic operation?Arithmetic operation is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots.
Now it is given that,
Number of guests invited = 33
Number of guests replied "will attend" = 8
Number of guests replied "will not attend" = 9
So, total guest replied = 8 + 9
⇒ total guest replied = 17
Thus, the guests (g) still need to reply = 33 - 17
⇒ the guests (g) still need to reply = 16
Thus, the guests (g) still need to reply are 16.

if you stop at random in front of an animal exhibit,What is the probability that you will be looking at monkeys? I put the table chart below
Answer:
1/10
step-by-step explanation:
----------------------------------
| animals | percent of animals |
----------------------------------
| goats | 16% |
----------------------------------
| camels | 4% |
----------------------------------
| giraffes | 6% |
----------------------------------
| llamas | 6% |
----------------------------------
| deer | 1% |
----------------------------------
| monkeys | 10% |
----------------------------------
| birds | 27% |
----------------------------------
| reptiles | 14% |
----------------------------------
| bears | 16% |
----------------------------------
( sorry if the table above isnt 100% right or straight ^ )
first you add up all the percents of how much animals are in this exhibit
16 + 4 + 6 + 6 + 1 + 10 + 27 + 14 + 16
= 100 %
then since we are looking for the probability of stopping in front of the monkeys, we take that 100 we got earlier and get the 10% of monkeys from our table
10/100
but since there isnt a 10/100 on the answers we look for something that equals to 10/100 and 1/10 does since you can just times both the 1 and 10 to equal the 10 and 100 you were looking for
1/10
making 1/10 your answer!

Clare said that 4/3 divided by 5/2 is 10/3 She reasoned: 4/3 x 5 equals 20/3 and 20/3 divided by 2 is 10/3 Explain why Clare's answer and reasoning are incorrect. Find the correct quotient.
Answer: See explanation
Step-by-step explanation:
4/3 ÷ 5/2
To solve this further, the minus sign changes to multiplication and the inverse of 5/2 is written. This will be:
= 4/3 ÷ 5/2
= 4/3 × 2/5
= 8/15
Claire's reasoning is wrong as she didn't multiply by the inverse of the number.
Veronica took her friend out for a birthday dinner. She purchased an appetizer
for $7.95, two entrées for $12.95 and $15.95, two drinks for $3.50 each, and two
desserts for $6.95 each. She had a 25% off coupon. A sales-tax rate of 9.25% was
then added. How much was the meal? If Veronica left a 20% tip, how much did
she leave for the tip? *
Answer:
Veronica left a tip of $6.87
Step-by-step explanation:
3.50×2= 7
6.95×2= 13.9
7.95+12.95+15.95+7+13.9 = 41.8
0.25×41.8= 10.45
41.8-10.45= 31.35
0.0925×31.35 = 3
31.35+3 = 34.35
0.20×34.35 = 6.87
