Answer: the percent value-added time for this ride is 16.67%
Step-by-step explanation:
Given that;
Waiting time for Vera = 35 minutes
Length of Vera's ride = 7 minutes
total processed time will; ( 35 + 7 ) = 42 minutes
the percent value-added time for this ride = ?
so
Percentage value-added time of Vera will be
= (length of the ride / total process time) × 100
we substitute
⇒ (7 / 42) × 100
⇒ 0.16666 × 100
⇒ 16.67%
Therefore the percent value-added time for this ride is 16.67%
Hello from MrBillDoesMath!
Answer:
58
Discussion:
Suppose the 2-digit number is "ab". That is, 10a + b.
Sum of digits = 13 => a + b = 13 (*)
Digits reversed if 27 added to number => (10a + b) + 27 = 10b + a (**)
(**) =
(10a + b) + 27 = 10b + a => subtract 10b, then a, from both sides
9a -9b = -27 => divide both sides by 9
a - b = -3
From (*), a+ b = 13 so
(a-b) + ( a+b) = -3 + 13 =>
2a = 10 =>
a = 5
As a +b = 13, 5 + b = 13 => b = 8
Hence the number "ab" is 58
Thank you,

The slope of a line is rise over run, which is the change in y over the change in x. Here, the change in y over the change in x would simplify to (3-2)/(2-4). It does not matter what point you choose to put as the first value, but if you put that point as the first value for x, you have to do the same for y. This equation simplifies to our answer of a slope of 1/2 or 0.5
Answer:
f(x)=-2x+9
f(4)+3=?
let x equal to 4
f(4)=-2(4)+8
f(4)=-8+9=+1
f(4)=1
then add 3 to f(4)
f(4)+3=1+3
f(4)+3=4
and he need f(4)+3 so the answer is
4
that's it
