Answer:
379.94 square inches, or 379.94 in².
Step-by-step explanation:
The area of a circle is π r². The diameter of the circle is listed as 22 inches, and the radius, or "r", is equal to half of the diameter. So, half of 22 is 11.
Since the formula says r², 11 needs to be squared, or multiplied once by itself. 11 x 11 = 121, so the last part of the equation is to multiply 121 by π. Because pi is an irrational number that never ends, it is commonly accepted to use 3.14, or the first three digits of pi, as the value of pi in an equation.
With that, 121 x 3.14 = 379.94, giving a final answer of 379.94 in².

Answer:
C: (-3,6)
Step-by-step explanation:
add both equations
5x+2x+2y-2y=-15+(-6)
7x=-21
x=-3
input x=3 into any equation in system and solve for y
2(3)-2y=-6
-2y=-12
y=6
solution: (-3, 6)

Roberto is going to the zoo! The entrance fee is $25 and each souvenir costs $3.75. He
has $40. Roberto thinks that this inequality could be use to find the number of souvenirs
he can purchase. Is he correct?
3.755 + 25 < 40
No the inequality symbol should be greater than or equal to
No it should be minus 25
No the letters should be next to the 25
yes this is correct
Answer:
yes this is correct

The angle of depression between the top of a 100-foot cliff and a ship approaching the shore is 37. What is the approximate distance, d, between the bottom of the cliff and the ship?
Answer:
76 feet
Step-by-step explanation:
let 'd' = distance from bottom of cliff and ship
sin 37 = sin 53
d 100
0.61 = 0.8
d 100
cross-multiply: 61 = .8d
d = 76
I assumed the bottom of the cliff and the shore formed a 90 degree angle - which leaves the 37° angle and a 53° angle

the mass of earth is approximately 5.9x10^24 kg, and the mass of venus is approximately 4.9x10^24 kg. find their combined mass
Answer:
28.91×10^48
hope it helps.
Because they both have the same exponent, just add the numbers together:
5.9 + 4.9 = 10.8
So now you have:
5.9 x 10^24 + 4.9 x 10^24 = 10.8 x 10^24
A scientific number can only have 1 number to the left of the decimal, so you need to move the decimal one place to the left. When you move the decimal to the left you add to the exponent.
The answer is: 1.08 x 10^25

The Quick Change Oil Company has a number of outlets in the metropolitan Seattle area. The daily number of oil changes at the Oak Street outlet in the past 20 days are:
65 98 55 62 79 59 51 90 72 56
70 62 66 80 94 79 63 73 71 85
The data are to be organized into a frequency distribution.
Click here for the Excel Data File
How many classes would you recommend?
Organize the number of oil changes into a frequency distribution. (Round "Relative frequency" answers to 2 decimal places.)
Answer: 5 classes.
Step-by-step explanation:
You can use the rule to determine the number of classes for a frequency distribution.
The rule says that where
is the number of classes
is the number of the data points
We know that the number of data points is = 20.
Next, we start searching for so that we can get a number 2 to the that is larger that the number of data points.
This suggests that you should use 5 classes.

Answer:
A. m<R, m<S, m<Q
Step-by-step explanation:
In a triangle, the length of each side determines the size of the angle opposite it. Thus, the longer the side, the bigger the size of the angle opposite it. The shorter the side, the smaller the size of the angle opposite it.
In ∆QRS, we have the following:
✔️The longest side is RS = 16. <Q is opposite to RS, therefore <Q is the largest angle.
✔️The medium side is QR = 15. <S is opposite to QR, therefore <S is the medium angle.
✔️The shortest side is SQ = 9. <R is opposite to SQ, therefore <R is the smallest angle.
From smallest to the largest we would have:
m<R, m<S, m<Q
round to the nearest hundredth if so. Use 3.14 as pi

d =
C=78.8 ft
Answer: The radius is 12.54 feet, and the diameter is 25.08 feet.
Explanation: By applying the circumference into the equation r = [tex]\frac{C}{2\pi }[/tex], we get r = [tex]\frac{78.8}{2\pi }[/tex]which simplifies the radius. And since radius is half of diameter, we multiply by 2 to get the diameter as well to solve the other blank in the problem.
Hope this helps! :D
