X=number of miles
$329=$175+$0.70x
329-175=.70x
154=.70x
154/.70=x
220miles =x

Hope this helps
Answer: A.
Step-by-step explanation:
To answer this, you must first understand what fractional exponents mean.
An exponent of 1 is simply the base itself. 7^1 = 7.
An exponent of 2 is squaring the base: 7^2 = 49.
An exponent of 1/2 is taking the square root of the base: 7^(1/2) = sq root of 7
Therefore, an exponent of 1/3 is taking the cube root of the base.
In this case, the base is 2.03 * t.
Therefore, this can be represented as the cube root of the product of 2.03 and the age of the mammal, so the answer is A.
Answer:
1.5hours
Step-by-step explanation:
Firstly in this question, we convert the time given to minutes.
Using the conversion of 60 seconds make a minute, we have 3/4 hours as 3/4 * 60 = 45 minutes. Let’s add this to a total of 3 hours which is 180 minutes. This gives a total of 225 minutes.
Now, we are told that he spends 2/5 of his time lifting weight. This is equivalent to 2/5 * 225 = 90 minutes
We convert this to hour = 90/60 = 1.5 hours
Hello from MrBillDoesMath!
Answer: 2 ^ -4 ( = 1/16)
Discussion:
- 4 log {8} 2 {8} is used instead of subscript notation
Basic property of logarithms is that exponents become multipliers and vice versa:
-4 log {8} 2 = log {8} (2^ -4)
Thank you,
