To convert these numbers to a percent, divide the subset by the total, then multiply by 100.
$241.50 (subset) divided by $1,050 (total)
Is 0.23. Next, multiply the quotient (0.23) by 100 to get your answer.
0.23*100 = 23.
The interest rate would be 23%.
0.25x - 0.5y = 8 |multiply both sides by 8
2x - 4y = 64
Answer:
<h2>18</h2>
Step-by-step explanation:
The formula of a distance between two points:
We have the points (5, -7) and (5, 11). Substitute:
Answer:
8.058655822 mins
Step-by-step explanation:
We have a table and to solve for this we might want to find the equation for this
This is a exponential function
To solve for this we need the rate of decay and the x intercept
We know the x intercept is 180 because in 0 mins the temp is 180
To solve for decay we need to know the temp of the cake after 1 min
to get the decay value we can do
125= 180 (x)^5
.69444444444 = x^5
0.929667185 = x
so the equation would be
180 (0.929667185)^x
if we tell this equation to equal 100
we get
100 = 180 (0.929667185)^x
.5556 = (0.929667185)^x
log .5556 = log 0.929667185 *x
log .5556 / log .929667185)
8.058655822= x
After 8.058655822 mins the cake will be 100 degrees
