Leon has $50 in a savings account that earns 10% interest, compounded annually. To the nearest cent, how much interest will he earn in 2 years?
Answers
Answer:
$10.50
Step-by-step explanation:
Interest = future value - amount saved
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
$50 x (1.1)^2 = $60.50
Interest = $60.50 - $50 = $10.50

Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school. If Angela works alone, it will take her five and a half hours. If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?
Answers
Answer:
3.08 hours
Step-by-step explanation:
Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.
If Angela works alone, it will take her five and a half hours.
If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?
This is calculated as:
The Number of hours they worked together = T
1/5.5 + 1/7 = 1/T
= 7 + 5.5/(5.5)(7)
= 12.5/38.5
1/T = 12.5/38.5
Cross Multiply
12.5T = 38.5
T = 38.5/12.5
T = 3.08 hours
The time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,
[tex]W_1=\dfrac{1}{n}[/tex]
In preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.
If Angela works alone, it will take her five and a half hours. The work done by Angela in one hour is,
[tex]A=\dfrac{1}{5.5}\\A=\dfrac{2}{11}[/tex]
If Brandon works alone, it will take him 7 hours. The work done by Brandon in one hour is,
[tex]B=\dfrac{1}{7}[/tex]
The work done in one hour, when the work together,
[tex]A+B=\dfrac{2}{11}+\dfrac{1}{7}\\A+B=\dfrac{14+11}{77}\\A+B=\dfrac{25}{77}\\A+B=\dfrac{1}{3.08}[/tex]
Thus, the time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.

A piece of copper tubing is in the shape of a hexagonal prism. The area of the base of the prism is 3 square centimeters. The volume of the prism is 51 cubic centimeters. What is the height of the tubing?
Answers
Answer: 17 cm
Step-by-step explanation:
For a regular figure where the area of the base is B, and the height is H, the volume is calculated as:
V = B*H
Here we know that the base of the prism is B = 3 cm^2, and the volume of the prism is 51 cm^3
Then:
B = 3cm^2
V = 51cm^3
If we replace those in the equation above, we get:
51 cm^3 = (3cm^2)*H
Solving this for H gives:
(51 cm^3)/(3 cm^2) = H = 17 cm
The height of the tubing is 17 cm

Step-by-step explanation:
Using the sine ratio in the right triangle on the left and the exact value
sin45° = [tex]\frac{\sqrt{2} }{2}[/tex]
let the altitude of the outer triangle be h ( common to both right triangles )
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{8}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )
2h = 8[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
h = 4[tex]\sqrt{2}[/tex]

Using the tangent ratio in the right triangle on the right and the exact value
tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then

Answer:
The length of the missing side is 8.
Step-by-step explanation:
to find the missing side, use the following formula:
[tex]a^{2} = c^{2} - b^{2}[/tex]
(c = hypothenuse) (a and b = sides) ( a = missing side)
[tex]a^{2} = 17^{2} - 15^{2}[/tex]
[tex]a^{2} = 289 - 225[/tex]
[tex]a^{2} = 64[/tex]
[tex]\sqrt{a^{2} } = \sqrt{64}[/tex]
a = 8

Multiplication is the process of multiplying. The product (1+i)(2+i) is (1+3i).
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The product (1+i)(2+i) can be done as,
(1+i)(2+i)
= 2 + i + 2i + i²
= 2+ 3i -1

Find the x- and y-intercepts of the graph of 3x + 2y = 20. State your answers as
whole numbers or as improper fractions in simplest form.
Answers
The x-intercept is given by the coordinates as (x, 0)
i,e y = 0
The y-intercept is given by the coordinates as (0, y)
i.e x = 0
The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3
The y-intercept of the graph of 3x + 2y = 20 is at y = 10
What are coordinates in a graph?
The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
3x + 2y = 20
The x-intercept is given by the coordinates as (x, 0)
i,e y = 0
The y-intercept is given by the coordinates as (0, y)
i.e x = 0
Now,
3x + 2y = 20
Putting x = 0 in (1) we get the y-intercept.
3x + 2y = 20
3x0 + 2y = 20
0 + 2y = 20
2y = 20
Divide both sides by 2.
y = 20/2
y = 10
Putting y = 0 in (1) we get the x-intercept.
3x + 2y = 20
3x + 2 x 0 = 20
3x + 0 = 20
3x = 20
Divide both sides by 3.
x = 20/3
Thus,
The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3
The y-intercept of the graph of 3x + 2y = 20 is at y = 10

At a school bake sale, all of the pies were cut into 6 pieces, so each person who bought a piece got ⅙ of a pie. Each slice sold for $2. The were sold out. How much money did the kids make if there were 11 pies sold? B. How many slices were sold?
Answers
Answer:
They made 132$, and 66 slices were sold.
Step-by-step explanation:
If all of the pies were cut into six pieces, and each piece costed $2, then you can multiply 6 x 2 to determine how much each pie cost. ($12)
If each pie costed $12 and there were 11 pies sold in total, then you can multiply 12 x 11 to find out how much money they made.
And to find out how many slices they sold you just have to multiply the 11 total pies by 6 because each pie had six pieces.
