Justin typed 90 words in 2 minute:
work
405/9=45 words a minute
45*2=90
Remmy typed 84 words in 2 minute:
work
420/10=42 words a minute
42*2=84
Izzy typed 98 words in 2 minutes:
work
588/12= 49 words a minute

I hope this helps :)
Let's say Set A = {1,2,3}, Set A can have subsets of:
{1}, {2}, {3}, {1,2}, {1,3}, {2,3}
This is 6 subsets.
Answer:$36.40
Step-by-step explanation
16 ounces in 1 pound
0.65 x 16 = $10.40
Peanuts
0.65 x 8 = $5.2 (you do this to get the extra 8 ounces)
$10.40 + $5.2 = $15.6
Pecans
$10.40 + $10.40 = 20.8
Total
$15.6 + 20.8 = $36.40
The angle of depression from the aeroplane to the ground will be 30 degrees.
<h3>What is trigonometry?</h3>
Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.
Given that:-
- An aeroplane is flying at the height of 10 km above the ground the distance along the ground from the aeroplane to the airport is 10√3 km
The angle of depression will be calculated as the angle between the horizontal and the height of the plane as shown in the figure below.
As we know that the perpendicular theta is height and the base ratio is angle tan theta.
tanФ = Height / Base
tanФ = 10 / 10 √3
tanФ = 1 / √3
Ф = tan⁻¹( 1 / √3 ) = 30°
Therefore the angle of depression from the aeroplane to the ground will be 30 degrees.
