Answer:
A
Step-by-step explanation:
The number is decreased by 23 which means 23 is subtracted from the number.
let the number be x, then
x - 23 = 44 ( add 23 to both sides )
x = 67
The number is 67
Answer:5.5
Step-by-step explanation:first we have to plus 4 and 7 and then we to divide the answer we get by 2 because there are only 2 digits and then the mean is 5.5
hope it helps
Answer:
66018.5 sq feet
Step-by-step explanation:
Area = πr²
To find the Radius R we need Diameter which 290 fee so:
R = Diameter / 2
R = 290/2
R = 145 ft
Now put values in Area Formula
Area = 3.14 x (145)^2
A = 66018.5 sq feet
Answer:
x = ± 2
Step-by-step explanation:
Given
x² = 24 ( take the square root of both sides )
x = ± 
= ± 
= ± 
× = ± 2
Step-by-step explanation:
y = x² - 16
x² = y + 16
x = sqrt(y + 16) because x is non-negative.
Hence the inverse function is f^(-1)(x) = sqrt(x + 16). (A)
