1. The amount of money in the account after 10 years is 42,317.96 dollars.
2. it will take Pamela and Kevin 7.5 hours to complete the task together
<h3>How to find compound interest?</h3>
Question(1)
Using compound interest formula,
where
- p = principal
- r = rate
- n = number of times
- t = time
Therefore,
p = 30,000
r = 3.5% = 0.035
t = 10
n = 1
Therefore,
A = $42,317.96
Question 2:
Pamela takes 12 hours to complete a task.
Kelvin takes 20 hours to complete same task.
The time it will take both of them can be computed as follows:
using rate principle,
let
x = time it will take both of them to do the work together.
cross multiply
240 = 32x
x = 240 / 32
x = 7.5 hours
Therefore, it will take Pamela and Kevin 7.5 hours to complete the task together

Answer:
0.3 or 30%
Step-by-step explanation:
The professors will only seek a smaller publisher if they cannot place the statistics book with a major publisher. If the probability of getting a major publisher is 40% and the probability of getting a smaller publisher is 50%, then the probability that the statistics book would wind up being placed with a smaller publisher is given by:
The probability is 0.3 or 30%.
<h2>Solution :</h2>
Area = 30 units²
Base = 5 units
Height = ? = Let it be -> x
Area (formula) = base×height = x×5 units= 30 units²
= x= 30/5 = 6 units
<h2>Thus , the height = 6 units</h2>
The measure of the ∠1 is 35 degrees.
<h3>How to determine the angle </h3>
it is important to know that the measure of an angle with its vertex outside the circle is half the difference of the intercepted arcs.
Also, the angle subtended by the arc at the center of the circle is the angle of the arc
From the diagram, we have
m ∠ of external angle = half of the difference of arc angles
The arc angles are
m ∠ of external angle = ∠ 1
Let's substitute the angles
∠1 = 
∠ 1 = 
∠ 1 = 35°
We can see that the external angle 1 measures 35 degrees.
Note that the complete image is added.
Thus, the measure of the ∠1 is 35 degrees.
