Answer: 12 inches to 1 foot.
Step-by-step explanation: Well, there is 12 inches in 1 foot, so the last one if I'm not mistaken. knowing this, 100 / 12 = 8.33
100 inches per minute converts to 8.33 feet per minute.
176ft^2 first
141.3ft^2 second
The answer is there as well as the explanation on why it should go there. hope this helps if it does please mark brainliest
Answer:
negative 21/9 times negative 18/7 is 6
Step-by-step explanation:
The phrase negative 21/9 times negative 18/7 can be written mathematically as
![-\frac{21}{9} \times -\frac{18}{7}](https://tex.z-dn.net/?f=-%5Cfrac%7B21%7D%7B9%7D%20%5Ctimes%20-%5Cfrac%7B18%7D%7B7%7D)
Lets first convert the fractions into decimal values
= -2.33
= -2.57
Now on simplyfying
=>![-2.33 \times -2.57](https://tex.z-dn.net/?f=-2.33%20%5Ctimes%20-2.57)
=> 5.988
=>6 (rounding off)
We will get a positive value because the multiplicative law states that the product of two negative number is positive
f(x) = 10x -5 and g(x) = (x+5)/10 are inverses of each other , Option D is the correct answer.
<h3>What is a Function ?</h3>
A function is a mathematical statement which relates two variables , a dependent and an independent variable.
The inverse of a function is found by replacing every y by x and vice versa , and then solve for y
The equation
f(x) = 4/x - 3
or
y= 4/x -3
Replacing y by x
x = 4/y -3
x +3 = 4/y
y = 4/(x+3)
Which do not correlate with the given inverse
f(x) = 10x -5
y = 10x -5
for finding inverse
10y -5 = x
10y = x+5
y = (x+5)/10
g(x) = (x+5)/10
Therefore , Option D is the correct answer.
