Answer:
(8,5)
Step-by-step explanation:
5x - 2y = 30
coordinates are (x,y) so you plug in 8 for x and solve for y
5(8) - 2y = 30
40 - 2y = 30
subtract 40 from both sides to isolate y
-2y = -10
divide both sides by -2 to isolate y
y = 5
Answer:
It is the 3rd choice. It is 4 times as big as the smaller cylinder
Step-by-step explanation:
V = πr2h
r - radius
h - height
π - pi
= π(3)2(10)
enter into a calucaltor and you get 282.74
= π(6)2(10)
enter into a calucaltor and you get 1130.97
Divide 1130 by 282 and you get about 4
Answer:
88.83
Step-by-step explanation:
To find the mean of a set of numbers is to find the average a set of numbers.
To solve for the mean you have to add all of the values together and divide that sum by the number of values there are.
Ex. 81, 97, 99, 89, 91, 76
81 + 97 + 99 + 89 + 91 + 76 = 533
533 / 6 = 88.83

Answer:
20:50
Step-by-step explanation:
2:5
They got 20 by multiplying 2 by 10 so we multiply 5 by 10 which is 50
This represents the function : y = log₆ (x).
Proof:
Rewrite this logarithmic function into an exponential form:
y = log₆ (x) ↔ x = 6^y
On the graph we see 2 major points A(1,0) and B(6,1). Plug them in x=6^y
1 = 6⁰ = 1 (true)
6 = 6¹ True, then this confirm that the graph equation is y = log₆ (x)
