Answer:
- absolute change: $6,999,148
- relative change: 81.79%
Step-by-step explanation:
The absolute change is the difference between the earnings numbers:
$15,556,113 -8,556,965 = $6,999,148
__
The relative change is the ratio of this difference to the original amount:
$6,999,148/$8,556,965 × 100% ≈ 81.794748% ≈ 81.79%
Answer:
0.5 Inches per hour
Step-by-step explanation:
Most normal people won't know exactly what unit rate is, or how to calculate it. So I'm here to help!
This is a fraction equal to
6 inches ÷ 12 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 12
6 inches ÷ 12
12 hours ÷ 12
=
0.5 inches
1 hour
=
0.5 inches
hour
= 0.5 inches per hour
Glad I was able to help!
Solve simultaneously.
4x - y = 8
6x + y = 2
Multiply top equation by 6, and bottom equation by 4, to eliminate x, so that we can find y.
~
24x - 6y = 48
24x - 4y = 8
Subtract top from bottom to form one equation.
~
-2y = 40
Therefore y is 20.
Put y back in to an equation, such as 4x - y = 8.
~
4x - 20 = 8
4x = 28
x = 7
SOLUTION
From the question, we are told that y varies inversely as x
This is mathematically written as

Now, we will remove the proportionality sign and replace it with equal to sign =
If we do this, we will intoduce a constant k

So we have the formula

We will substitute the values of x for 10 and y for 8 into the formula to get k, we have

Now, we will substitute k for 80 back into the formula to get the inverse function, we have

Hence the answer is option C
4.5. because ⁼3=9, and 9 divided by 2 is 4.5
