49t^8 is the correct answer
Answer:
16%
Step-by-step explanation:
To solve this we are using the standard growth equation:
Were
is the final value after years
is the initial value
is the growth factor (yearly rate of appreciation in our case) in decimal form
is the time in years
We know from our problem that gold coin appreciated in value from $200.00 to $475.00 in 6 years, so , , and .
Let's replace the values in our equation and solve for :
which rounds to
Since our appreciation rate is in decimal form, we need to multiply it by 100% to express it as percentage:
0.16*100% = 16%
We can conclude that the yearly appreciation rate of our gold coin is approximately 16%
Answer:
Percentage error is 39.39%
Step-by-step explanation:
It is given that,
The calculated value that Erika spend on school supplies this year is $115.
Actual value that she spent is $82.50.
We need to find Erika's percent of error. Percentage error is given by the formula as follows :
So, Erika's percent of error is 39.39%.
Answer:
Yes it is
Step-by-step explanation:
When we simplify 15:12, we receive 5:3
Therefore, 5:3 is equvilaent to 15:12
Using this unit ratio, we can solve for other rations
For example, 5:3, the unit ratio, times 2 is 10:6
5 * 2 = 10
3*2 = 6
10, 6 = 10:6
If you're asking how, here's an example
A standard form equation is when it is set up.
Ax + By = C.
6x + 2y = 4.
A slope-intercept form equation is when it is set up y=mx+b.
Y = - 3x + 2.
4y = -8x + 16 then divide all by 4.
y = -2x + 4 slope form.
