how to calculate interest on a loan
Answer:
Gather information like your principal loan amount, interest rate and total number of months or years that you’ll be paying the loan.Calculate your total interest by using this formula: Principal Loan Amount x Interest Rate x Time (aka Number of Years in Term) = Interest.If you take out a five-year loan for $20,000 and the interest rate on the loan is 5 percent, the simple interest formula works as follows:
$20,000 x .05 x 5 = $5,000 in interest
You might encounter simple interest on short-term loans. However, the way most banks and lenders charge interest is more complicated.

: Scottie is standing next to a lighthouse on the edge of a cliff overlooking the ocean. The cliff is 30 meters above sea level, and the lighthouse has a height of 15 meters. There is a man fishing in a boat directly below Scottie who has hooked a fish that is 10 meters below the surface of the water.
Complete question :
Scottie is standing next to a lighthouse on the edge of a cliff overlooking the ocean. The cliff is 30 meters above sea level, and the lighthouse has a height of 15 meters. There is a man fishing in a boat directly below Scottie who has hooked a fish that is 10 meters below the surface of the water.
a. Use positive and negative numbers to represent the locations in relation to sea level.
Scottie =
Top of the lighthouse =
The boat =
The fish =
b. How far is Scottie from the fish?
meters.
Answer:
Scottie = +30 m
Lighthouse = +45m
Boat = 0
Fish = - 10m
40 m
Step-by-step explanation:
Scottie = 30m ( height of the cliff) since he is standing on it's edge
Top of lighthouse = since, lighthouse is located on top of the cliff ; height of cliff + height of light house = (30 + 15) = 45m
The boat = 0 (on the surface of water) ; this is the sea level surface or point
The fish = - 10 m (10 meters below the water surface).
Distance between scottie and fish :
30 m - ( - 10m)
30m + 10m
= 40 m

Charlotte invests £5000.
The bank pays 10% interest for the first year and then y% every year after that.
After three years, Charlotte has £5610.55
Calculate y
Answer:
y = 1%
Step-by-step explanation:
From the formula;
Interest; i = PRT/100
P = £5000
R = 10%
After 1 year, we have;
i = 5000 × 10 × 1/100 = £500
Amount is now; 5000 + 500 = £5500
Since interest rate is now y% every year after the first one, then;
After 2nd year;
i = (5500 × y × 1)/100
i = 55y
So amount is now;
5500 + 55y
After 3rd year, interest is now;
i = (5500 + 55y) × y × 1/100
i = 55 + 0.55y²
Amount is now;
(5500 + 55y) + (55 + 0.55y²)
Since she has £5610.55 after 3 years, then;
(5500 + 55y) + (55 + 0.55y²) = 5610.55
0.55y² + 55y + 5555 - 5610.55 = 0
0.55y² + 55y - 55.55 = 0
From quadratic formula, y = 1%

- 11x - 19 = - 41
solve for x
Answer:
-11x -19 = -41
We need to add 19 to both sides then divide to find x.
_____________________
1)) so -11x -19 + 19 = -41 + 19
2)) -11x = -22
3)) -11x/-11 = -22/-11

GL!
(side note, i dont usually ask, but it would be great if you could mark me brainliest so I can level up <33)
Answer:
x = 2
Step-by-step explanation:
-11x - 19 = -41
Add 19 to both sides of the equation:
-11x - 19 + 19 = -41 + 19
-11x = -22
Divide both sides by -11
-11x/-11 = -22/-11
x = 2

For the line above, what is the slope? *
Answer: The slope is 2.
Step-by-step explanation:
To get the slope, use this tip: Rise over run
Count how much it rises, which is 4, and how much it "runs' which is 2. Now put rise above run which is 4/2. This simplifies to simply 2.
Answer:
The slope is 2.
Step-by-step explanation:
The points on the line are (1, -2) which can be labeled as x1 and y1, and the other is (3,2) which can be labeled as x2 and y2. you set up the equation in the slope formula, so 2 - - 2 / 3 - 1. Since there are two negatives, the subtraction signs turn into addition signs, and you get 4/2, which simplyfied is 2. Hope this helps :)

A pendulum is swinging back and forth. After ttt seconds, the horizontal distance from the bob to the place where it was released is given by \qquad H(t) = 7 - 7 \cos \left(\dfrac{2\pi (t-2)}{20}\right)H(t)=7−7cos( 20 2π(t−2) )H, left parenthesis, t, right parenthesis, equals, 7, minus, 7, cosine, left parenthesis, start fraction, 2, pi, left parenthesis, t, minus, 2, right parenthesis, divided by, 20, end fraction, right parenthesis. How often does the bob cross its midline? Give an exact answer
Answer:
Every 10 seconds
Step-by-step explanation:
The bob crosses its midline whenever cos(2π(t-2)/20)=0.
Since cosθ=0 when θ=±π/2 + 2πn, we can find then the bob crosses its midline by solving:
2π(t-2)/20 = ±π/2 + 2πn
t-2 = ±5+20n
The solutions are when t = -3, 7, 17, 27, 37, ...
Therefore, the bob passes its midline every 10 seconds.
The original rectangle is 120 centimeters. Calculate the length of a rectangle that is 72% shorter.
What is the answer
Answer:
33.6 cm
Step-by-step explanation:
120 x 0.72 = 86.4
120 - 86.4 = 33.6
The new rectangle which is 72% shorter is 21.6 centimeters.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given The original rectangle is 120 centimeters.
And the new rectangle is 72% shorter or (100 - 72)% = 18% of the original rectangle which is,
= (18/100)×120 centimeters.
= 21.6 centimeters.

Solve the simultaneous equations
5x + 3y = 41
2x + 3y = 20
Do not use trial and improvement
The solution to the system of equation is (7, 2)
Using the simultaneous equation:
5x + 3y = 41
2x + 3y = 20
using elimination method
Subtract equation 1 from 2 to have:
5x - 2x = 41 - 20
3x = 21
x = 21/3
x = 7
Substitute x = 7 into equation 1 to get y
5x + 3y = 41
5(7) + 3y = 41
35 + 3y = 41
5y = 41 - 35
3y = 6
y = 6/3
y = 2
Hence the solution to the system of equation is (7, 2)

Given the function h(x)=-x^2+x+4, determine the average rate of change of the function over the interval −1≤x≤5.
Answer:
average rate of change of h(x) on −1 ≤ x ≤ 5 is then 5
Step-by-step explanation:
change in h(x)
average rate of change = ------------------------
change in x
Calculate h(x) at the interval endpoints: -1 ≤ x ≤ 5, and then subtract h(5) from h(-1):
h(5) = (5)² + 5 + 4 = 34
h(-1) = (-1)² -1 + 4 = 4
change in h(x) = 34 - 4 = 30
change in x: 5 - (-1) = 6 30
average rate of change of h(x) on −1≤x≤5 is then ------------- = 5
