Answer:
x=-2
Step-by-step explanation:
To solve this, let's set the two exponents so that they have the same base. We know that 9 is 3², so we can rewrite the left side as (3²)^(x-8), which simplifies to 3^(2x-16). Now, we have 3^(2x-16) = 3^(4x-12). Since the bases are equal, the exponents are also equal. Therefore, 2x-16 = 4x-12. When we solve, we get -2x = 4, so x=-2. Hope this helps!
Here's what we know:
4t = 7/10 (4 tasks take 7/10 of an hour)
Divide both sides by 4:
4t / 4 = 7/10 / 4
t = 7/40
So each task is 7/40 of an hour
7/40 n = 1 (Now we want to find the number of tasks completed in 1 hour)
Multiply both sides by 40/7:
n = 40/7
Converting improper fraction to a mixed number:
n = 5 5/7
So the robot will complete 5 5/7 tasks in an hour. If the answer is looking for fully finished tasks and not partially done ones, the you need to round down to 5.
Since James is further and Megan is closer.
You would take James's distance and divide it by Megan's distance.
3.42/0.76 = 4.5
Answer: So James is 4.5 times as long as Megan's.
The answer is 3.5 inches for K12 test
All i did was see what coud make 49 feet.
since 1 inch = 14 feet then i did 3 x 14 which got 42.
I then just shuffled around numbers and got 3.5.
THE ANSWER IS 3.5
Very sorry if its wrong
The slope of BC is
(4-2)/(-3-2) = -2/5
The slope of AD is
(-2- -4)/(-2-3) = -2/5
The slope of CD is
(2- -4)/(2-3) = -6
The slope of BA is
(4- -2)/(-3- -2) = -6
BC ∥ AD and CD ∥ BA because their slopes are equal. Therefore, ABCD is a parallelogram because both pairs of opposite sides are parallel.
