Answer:
Rational, because it is a fraction.
Step-by-step explanation:
A number which can be represented in the form of p/q where p belongs to integers and q belongs to natural numbers.
=34/3=11.3333
Since 34 and 3 do not have any common factor other than 1, it is a rational number. The numerator p=34 belongs to integers and the denominator q=3 belongs to natural numbers. Also, the decimal expansion is a non-terminating decimal since it does not end.
The height of the tower is 452.66 ft
<h3>What is angle of elevation and depression?</h3>
The angle formed by the line of sight and the horizontal plane for an object above the horizontal.
The angle of depression is the angle between the horizontal line and the observation of the object from the horizontal line.
Given:
we have two angles one of which is angle of elevation and another angle depression.
Using trigonometric ratio,
tan ∅ = P / B
tan 32° = h / 425
0.624= h /425
h= 265.569 ft
again,
tan 29° = h(bottom of the tower) / 425
h(bottom of the tower) = 425 × tan 29°
h(bottom of the tower) = 235.581 ft
Thus, Height of tower = h(top of the tower) + h(bottom of the tower)
Height of tower = 265.569 + 235.581
Height of tower = 501.15 ft

Answer:
y=-2/3x-2
Step-by-step explanation:
-2/3 is the slope and -2 is the y intercept
y=mx+b
m is slope and b is y intercept
This question might look tough, but if we break it down, it's super easy! I'll walk you through the steps.
Firstly, we need to figure out the total amount of money she deposited over the 10 months. To figure this out, all we have to do is multiply the $76.50 per month by the 10 months.
76.50 * 10 = 765
There we have it. She deposited a total of $765 over the course of the 10 months. On to the next step.
Second, we need to figure out the total amount of money she spent over the 10 months paying for singing lessons. To do that, all we have to do is multiply the $30.50 it took for each month by the 10 months.
30.50 * 10 = 305
There it is! She spent a total of $305 on singing lessons over the 10 months. On to the next step.
Now, we must subtract the cost of the singing lessons over 10 the months by the amount she deposited over the 10 months. Since she deposited a total of $765 and she spent $305 on singing lessons, here's the equation we're doing.
765 - 305 = 305
There we go! She had a total of $305 left after the 10 months. I'll leave the last step to you, I know you can do it!
