Answer: $10
Step-by-step explanation:
Let's analize the information given: We know that she had $94 to spend on 8 books and after buying these books she had $14. So, we need to calculate the amount of money she spent. Subtract $94 and $14:
Then, to calculate the cost of each book, we need to divide the "Total spent" by 8:
To solve this problem you must apply the proccedure shown below:
1. You have the following logarithm:
<span>log(2)n=4
2. Therefore, you con rewrite it as below:
loga(b)=logb/loa
</span>
3. Therefore, you have:
log(2)n=4⇒log(n)/log(2)=4
4. Then, you obtain:
log(n)=4log(2)
5. Therefore, as you can see, the answer for the exercise shown above is the last option, which is:
log(n)=4log(2)
Answer:
281
Step-by-step explanation:
plug y value into expression
86(32) + 25 - 78(32)
pemdas says we must multiply first
2752 + 25 - 2496
2777 - 2496
281
Answer:
B). 37.68 feet.
Step-by-step explanation:
Circumference = diameter * π
= 12 * π
= 37.68 feet.
When dividing by a multiple of 10, depending on if it's greater than 0, The decimal place would move. In this case, the decimal place in 34.5 would move more to the left making the answer 3.45.
