Answer:
Step-by-step explanation:
Firstly you could expand the indices
This would give you
5 x 5 x 5
This is because 5² is equivalent to 5 x 5
5 x 5 x 5 =125
But we have to give the answer in index form
This means the answer is 5 cubed or 5³
It is "FALSE". In the problem, the expression is a^b where the variable "a" is called the base and the variable "b" is called the "EXPONENT or power". So, from the given problem, it is incorrect the "b" is called numerator.
Answer:
<em>He would pay $287 if he races 39 times</em>
<em>Thus, the membership fee is $14.</em>
Step-by-step explanation:
<u>Linear Modeling</u>
The situation described in the problem can be modeled as the equation of a line which has the form:
![y=ax+b](https://tex.z-dn.net/?f=y%3Dax%2Bb)
Where y is the cost of the course, x is the number of races, a is the cost per race, and b is the membership fee.
We know the course charges $7 per race, so a=7. Since your friend has raced x=28 times and paid y=210, we can find the value of b:
![210=7(28)+b](https://tex.z-dn.net/?f=210%3D7%2828%29%2Bb)
Operating:
![210=196+b](https://tex.z-dn.net/?f=210%3D196%2Bb)
b=14
Thus, the membership fee is $14.
The linear model is now:
![y=7x+14](https://tex.z-dn.net/?f=y%3D7x%2B14)
If he races x=39 times, your friend would pay:
![y=7(39)+14=287](https://tex.z-dn.net/?f=y%3D7%2839%29%2B14%3D287)
y=287
He would pay $287 if he races 39 times
40% of 15 = 6
The number that cannot be a solution to the inequality x > -3 is
-3
(-4)2 ÷ (-8) = ?
1
___% of 750 = 37.5

20% of 25 = 5
If you can travel from Orlando to Miami (240 miles) in 4 hours; how long would it take you to travel from Ft. Lauderdale to Tallahassee (420 miles)?
7 hours
If 3500 miles are traveled at a rate of 175 miles per hour, what is the time in hours? (hint: Distance = Rate * Time)
20 hours
3(x+4) - 6x < -9
The solution to this inequality is
x > 7
If Lance Armstrong can average 32 mph for 90 minutes, he will have traveled 48 miles.
5% of 320 = 16?
Surface area is measured in cubic units or units3
False
6% of 300 = 18
-2x + 4 < -12
x < 8
(3x^5 + 8x^3) - (7x^2 - 6x^3) = 3x^5 + 8x^3 - 7x^2 - 6x^3 = 3x^5 + 2x^3 - 7x^2
