Answer:
d. 32.9
Step-by-step explanation:
To find c, we'll use the Law of Sines that says:
And we'll isolate a to get:
We first need to find A, which is easy. The sum of the interior angles of a triangle is 180 degrees... and we already have 2 of them, so:
A = 180 - 90 - 47.3 = 42.7
(converted 47°18' to 47.3)
Then we will plug-in the information we already have
So, let's round it to 32.9 to match the answer number D.
The answer is A
One revolution is equal to the circumference of the tire:
C=2pi r=2(1)(frac{22}{7})=\frac{44}{7}
The car travels at 4,400 ft per minute. To calculate the number of revolutions, divide the speed by the circumference:
4,400div frac{44}{7}=4,400times frac{7}{44}=700
700 revolutions.
Answer:
$42.84
Step-by-step explanation:
There are two ways to do this.
One
19% of 36 = 19/100 * 36 = $6.84
Total 36 + 6.84 = $42.84
Two
The second method involves knowing that his total is going to wind up being 119% of the bill. That's 100% + 19%
So the equation look like this
(119/100) * 36
or
(119 * 36) / 100 = 4284 / 100 = $42.84
Note
Both methods give you the same answer.
Answer:
C. The axis is flipped at that point.
