Justin borrowed money from a credit union for 2 years and was charged simple interest at an annual rate of 7%. The total interest that he paid was $840. How much money did he borrow?
Answers
Justin borrow $6,000 from a credit union for 2 years.
What is Principal amount?
The amount of money initially borrowed from the lender, and as the loan is repaid, it can also refer to the amount of money still owed, is called Principal amount.
Given that;
Simple interest = $840
Time = 2 years
Annual rate = 7%
Now, The formula for calculate the principal amount is,
Simple interest = Principal amount × Rate × time / 100
Principal amount = Simple interest × 100 / Rate × time
Hence,
Principal amount = 840 × 100 / 7 × 2
Principal amount = 84,000 / 14
Principal amount = $6000
So, Justin borrow $6,000 from a credit union for 2 years.

The value of the expression 6y + 10z - 2yz when y = 2 and z = 3 is 30.
What is the value of the expression when y=2 and z=3?Given the expression in the question:
6y + 10z - 2yz
y = 2
z = 3
To determine the value of the expression 6y + 10z - 2yz, we simply substitute y = 2 and z = 3 into the expression and then simplify.
6y + 10z - 2yz
Plug in y = 2:
6( 2 ) + 10z - 2(2)z
Plug in z = 3:
6( 2 ) + 10( 3 ) - 2(2)(3)
Simplifying, we get:

Answers
The bird settles on the branch at the rate of 2.33 meters per second.
What is the rate of change?The rate of change refers to the traveling speed of the bird when perching on the branch.
The rate of change (which is speed) is the distance (altitude) divided by time.
Data and Calculations:The bird's flying altitude above ground = 10 meters
Time in seconds to settle on a branch = 3 seconds
The altitude above ground after settling on the branch = 3 meters
The change in altitude = 7 meters (10 - 3)
Rate of change = 2.33 meters per second (7/3)
Thus, the rate of change that the bird used to settle on the branch is 2.33 meters per second.

Answers
The speed with which the airplane is flying in feet per second is 917 ft per second.
The speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Given that it just has a direction and no magnitude, speed is a scalar number.
It is given that,
The speed with which the airplane is flying is = 625 mile per hour
We need to find the speed of the airplane in feet per second
Number of seconds in 1 hour = 60 x 60 = 3600s
Number of feet in 1 mile = 5280 feet
Number of feet in 625 mile = 5280 x 625 = 33,00,000 feet
Speed of airplane in feet per second = [tex]\frac{33,00,000}{3,600}[/tex]

(Use a thousands comma where applicable.)
Answers
The annual insurance premium that Will C. Lowe will be paying is $ 766.5
What is insurance premium?Insurance premium is annual, quarterly, semi annual or monthly payments that has to be paid accordingly to keep our insurance policy active.
Annual insurance premium can be calculated by multiplying the face value per $1000 of the policy by the rate of the insurance of policy.
Given is that Will C. Lowe is 31 year old male who wants to buy a ordinary whole life insurance policy with a face value of $50,000.
From the table we can see that rate of insurance for a 31 year old male for a ordinary whole life insurance policy is 15.33
Then annual premium = (face value per $1000)*(rate of insurance)
= $ (50,000/1000)*(15.33) = $766.5
Therefore, the annual insurance premium that Will C. Lowe will be paying is $766.5

A point on the edge of a symmetrical canyon is 4500 feet above a river that cuts through the canyon floor. The angle of depression from each side of the canyon to the canyon floor is 60o.

b) Find the distance across the canyon.
feet
c) Is it more or less than a mile across the canyon? (5280 feet = 1 mile) more or less
Answers
The length and distance across the canyon is 5196.15 feet and it is more than 1 mile.
a) To find the length of canyon, we will sine function. As per the sine theta = length of opposite side ÷ hypotenuse. Keep the values in formula to find the hypotenuse, which is the length of the canyon wall.
sin 60 = 4500 ÷ hypotenuse
Hypotenuse = 4500 ÷ (✓3/2)
Hypotenuse = 4500 × 2 ÷ ✓3
Hypotenuse = 9000 ÷ ✓3
Hypotenuse = 5196.15 feet
The length of the canyon wall is 5196.15 feet.
b) To find the distance across the canyon, we will use cosine function. As per the cos theta = base ÷ hypotenuse. Keep the values in formula to find the base, which is half the length of the distance across the canyon.
cos 60 = base ÷ 5196.15
cos 60 × 5196.15 = base
Base = (1/2) × 5196.15
Base = 2958.075 feet
Total distance across the canyon = 2958.075 + 2958.075
Tota distance across the canyon = 5196.15 feet
c) Using the relation, 5280 feet = 1 mile
5196.15 feet = 5196.15 ÷ 5280 mile
5196.15 feet = 1.12 miles
So, distance across the canyon is more than 1 mile.

Answers
The solution is 5
Rewriting the expression -
2(x+3)²/₃=8
Divide Left Hand Side and Right Hand Side of the equation -
(2(x+3)²/₃)÷2 = 8÷2
Performing division to find the solution
(x+3)²/₃ = 4
Taking cube on both sides of the equation
((x+3)²/₃)³ = 4³
The exponent on Left Hand Side will be multiplied cancelling 3, as it is common in both numerator and denominator
(x + 3)² = 64
Now, taking square root on both sides of equation
√(x + 3)² = √64
Solving the square root on both sides of equation
x + 3 = 8
Shifting 3 to Right Hand Side of the equation
