Answer:
-5/2
Step-by-step explanation:
log (2z) = log(6z+10)
When you have a single logarithm or ln in both sides of the ecuation, delete them
2z=6z+10
2z-6z=10
-4z=10
z=10 / -4
z= -5/2
Answer:
1.8 miles
Step-by-step explanation:
For this case we can model the problem as a rectangle triangle.
We know:
Length of the sides of the triangle
We want to know:
Length of the hypotenuse
Using the Pythagorean theorem we have:
Then, the distance that he would have saved if he travels directly is:
Answer:
he would have saved:
1.8 miles

Answer:
8 hours
Step-by-step explanation:
7x8=56-4=52 :)
First, find the digit in the place you are rounding to. Look at the digit one place to the right. If the digit is less than 5, round down. If the digit is 5 or greater, round up.
For example: round 1.86 to the nearest tenth
Look at the tenth digit (8). The number to the right of it is 6. Since it’s above 5, round the 8 up to 9. So you would get 1.9.
If it was 1.84, since 4 is less than 5, you would not round the 8, and you would get 1.8
