Answer:
False
Reasoning:
- It's an acute angle, 140 is obtuse
- Angles 6 and 8 are 140 degrees, so 5 can't be
Answer:
8.398
Step-by-step explanation:
If you are uncertain, you can do this with your calculator. However both numbers doing the dividing are powers of 10 so you can just move the decimal
8398 / 10 = 839.8 Move the decimal 1 place.
839.8/100 = 8.398 Move the decimal 2 places.
In both instances, move the decimal left.
Answer:
4
Step-by-step explanation:
2lw + 2hw + 2lh = 2(3)(2.2) + 2(7.5)(2.2) + 2(3)(7.5) = 91.2
2/4 is the fraction with the greatest value...
2(x+3)=7x-24
2x+6=7x-24
(move 7x to the left by subtracting from both sides, and move the 6 to the right by subtracting from both sides)
-5x=-30
(divide -5 from both sides to get x by itself, and because the 30 and 5 are both negative, two negatives make a positive)
x=6
hope this helped
