The interest is $57 on a $1900 investment at 3% for 1 year
Given,
In the question:
Principal = $1900
Rate of interest = 3%
Time = 1
Now, According to the question:
Principal = $1900
Rate of interest = 3%
Time = 1
Substitute:
Principal = $1900
Rate of interest = 3%
Time = 1 into formula Interest = P x R x T
I = 1900 x 0.03 x 1
Calculate the product or quotient:

small airplane flew 104 miles in 50 minutes. At this rate, how many miles can it fly in 3 hours?
An airplane can fly 374.4 miles in 3 hours.
A small airplane flew 104 miles in 50 minutes.
So, the rate would be,
rate = distance / time
rate = 104/50
rate = 2.08 miles/minute
We need to find the distance the airplane can flay in 3 hours.
3 hours = 180 minutes
t = 180 minutes
r = d/t
2.08 = d/180
d = 2.08 * 180
d = 374.4 miles
Therefore, an airplane can fly 374.4 miles in 3 hours.

The answer is one because the graph starts at 12$ and Wallace only needs $8.
1/2v + 8 = 3 – 1/3v plss
Answer:
v = -6
Step-by-step explanation:
½v + 8 = 3 - ⅓v
Collect like terms
½v + ⅓v = 3 - 8

Divide both sides by ⅚
⅚v/⅚ = -5/⅚
v = -5 × 6/5
v = -30/5

Simply put, probability is the likelihood that something will occur.When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.Statistics is the study of events that follow a probability distribution.
calculate the probability she chooses 2 socks of the same colour ?I clarify this because the question uses plural “drawing white socks”. Ok, in our language practice one does usually say socks instead of sock because they usually come in pair.
If it means 1 draw of 1 sock then the probability is 6out of 21. Or about 28.57%

Step-by-step explanation:
( 2k - 2 )°, 90° and ( k + 2 )° are linear pair angles.
Sum of linear pair angle is supplementary ( that is 180 ),
2k - 2 + 90 + k + 2 = 180
2k + k + 90 = 180
3k = 180 - 90
3k = 90
k = 90/3
k = 30

(round your answer to two decimal places.)
The angle of depression from the top of the tower to a cell phone user who is 5 horizontal miles away and 200 feet above sea level will be 87.36 degrees.
What is angle?When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the word "angle" originates.
Here,
The cell phone tower's peak will be at a height of 1300 + 110 = 1410 feet above sea level.
Assuming that the user of a cell phone is 200 feet above sea level, the distance between them is 1410 feet- 200 feet, or 1210 feet.
The distance between them horizontally is 5 miles, or 5 * 5280, or 26400 feet.
The opposite cathetus is 26400 feet away and the neighboring cathetus is 1210 feet away.
the angle is 87.376 degrees, or tan(angle) = 26400 / 1210 = 21.82
