Willy has compounded monthly to invest his summer earnings of $4259 in the
Rock Solid Bank. The bank is offering 6%. Willy plans to use the money to go to
college in 5 years. How much will he have in 5 years?
We have been given that Willy has compounded monthly to invest his summer earnings of $4259 in the Rock Solid Bank. The bank is offering 6%. We are asked to find the amount of money will be after 5 years.
We will use compound interest formula to solve our given problem.
[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,
A = Final amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year.
t = Time in years.
[tex]6\%=\frac{6}{100}=0.06[/tex]
Since interest is compounded monthly, so [tex]n=12[/tex] and [tex]P=4259[/tex].
[tex]A=\$4259(1+\frac{0.06}{12})^{12\cdot 5}[/tex]
[tex]A=\$4259(1+0.005)^{60}[/tex]
[tex]A=\$4259(1.005)^{60}[/tex]
[tex]A=\$4259(1.3488501525493161)[/tex]
[tex]A=\$5744.752799707\approx \$5744.75[/tex]
Therefore, Will will have approximately [tex]\$5744.75[/tex] in 5 years.

Two cylinders have the same size base, but one is twice as tall. Explain why the taller cylinder does not have double the surface area
Answer:
Because surface area has nothing to do with how tall it is
Step-by-step explanation:
Surface area involves the base shape of the object, if both cylinders have a base of the same size and shape, then the surface area of the face of that object will remain the same. how tall the cylinder is would affect volume however.
Please mark brainliest :)
Answer:
Sample response: The surface area of a cylinder is the sum of the areas of the two bases and the area of the lateral surface. If the height of the cylinder is doubled, the area of the lateral surface is doubled, but the areas of the bases remain the same.Step-by-step explanation:

What is the best estimate of the lateral area of a cube with edges that are 2.1 inches long?
The best estimate of the lateral area of a cube with 2.1-inch edges is 17.64 square inches, calculated by squaring the edge length to find the area of one side (4.41 square inches) and then multiplying by four since there are four lateral faces.
The question asks for the best estimate of the lateral area of a cube with edges that are 2.1 inches long.
To calculate the lateral area of a cube, we need the formula for the lateral area, which is the sum of the areas of all the sides excluding the top and bottom faces. Since a cube has six faces, we have four lateral faces to consider.
The area of one face of a cube is obtained by squaring the length of one edge. In this case:
Area of one side = edge length × edge length = 2.1 inches × 2.1 inches = 4.41 square inches
Since there are four sides whose areas we need to count for the lateral area, we multiply the area of one side by four:
Lateral area = 4 × Area of one side = 4 × 4.41 square inches = 17.64 square inches
Therefore, the best estimate of the lateral area of the cube is 17.64 square inches.
Final answer:
The best estimate of the lateral area of a cube with 2.1-inch edges is approximately 17.64 square inches, calculated by squaring the edge length and multiplying by four since a cube has four lateral faces.
Explanation:
The goal is to estimate the lateral area of a cube with edges that are 2.1 inches long. The lateral area of a cube is the sum of the areas of all the sides of the cube, excluding the top and bottom faces. Since the cube has six faces and we only need the sides, we calculate for four faces.
Each face of a cube is a square, so to find the area of one face, we square the length of the edge:
Area of one side = Edge length × Edge length
Area of one side = 2.1 inches × 2.1 inches
Area of one side = 4.41 square inches
Since there are four sides whose area we are considering for the lateral area:
Lateral area = 4 × Area of one side
Lateral area = 4 × 4.41 square inches
Lateral area = 17.64 square inches
So, the best estimate of the lateral area of the cube is approximately 17.64 square inches.

Jessica can build a bookshelf in 4 hours. Sydney can build a bookshelf in 6 hr. How long will it take them if they build the bookshelf together?
Answer:
About 2.4 Hours
Step-by-step explanation:
1/4+1/6=1/h
12h(1/4+1/6)=12h(1/h)
3h+2h=12
5h=12
12/5=2.4
When working together, Jessica and Sydney can construct a bookshelf in 2.4 hours. This is based on their individual rates of work.
Explanation:This problem involves the concept of rates of work. We need to find out how long it will take for Jessica and Sydney to build a bookshelf together. Jessica builds one bookshelf in 4 hours, so her work rate is 1/4 bookshelves per hour. Sydney builds one bookshelf in 6 hours, hence her work rate is 1/6 bookshelves per hour.
When Jessica and Sydney work together, their work rates add together. So the combined work rate is 1/4 + 1/6 = 5/12 bookshelves per hour. Since they are building just one bookshelf, we can find the time it takes by dividing the number of bookshelves (1) by the work rate (5/12). Therefore, when working together, Jessica and Sydney can build a bookshelf in 12/5 or 2.4 hours.

In the figure, AC = 15 ft, m∠ABC = 60°, m∠ADC = 45°, and m∠AEC = 30°. Find each of the following measures. Show your work or explain your reasoning.
Answer:
a) BC = 8.66 feet
b) AD = 21.2134 feet
c) EC = 25.9785 feet
Step-by-step explanation:
a)
To find the length of BC, we just need to use the tangent relation of the angle ABC, where the opposite side is the length of AC and the adjacent side is the length of BC:
tangent(60) = AC / BC
1.7321 = 15 / BC
BC = 15 / 1.7321 = 8.66 feet
b)
To find the length of AD, we just need to use the sine relation of the angle ADC, where the opposite side is the length of AC and the hypotenusa is the length of AD:
sine(45) = AC / AD
0.7071 = 15 / AD
AD = 15 / 0.7071 = 21.2134 feet
c)
Similarly to the procedure in letter a), to find the length of EC, we just need to use the tangent relation of the angle AEC, where the opposite side is the length of AC and the adjacent side is the length of EC:
tangent(30) = AC / EC
0.5774 = 15 / EC
EC = 15 / 0.5774 = 25.9785 feet

1.Write the expression for when you translate the graph of y = x + 7 one unit to the left
2. Write the expression for when you translate the graph of y = 3x− 5 one unit to the right.
To translate y = x + 7 one unit to the left, the expression becomes y = x + 8. To move y = 3x - 5 one unit to the right, it becomes y = 3x - 8. The translation shifts the graph parallel to the x-axis while maintaining its shape.
To translate the graph of the function y = x + 7 one unit to the left, we substitute x with (x + 1) because adding to the independent variable moves the graph to the left.
Therefore, the translated expression would be y = (x + 1) + 7 which simplifies to y = x + 8.
Similarly, to translate the graph of the function y = 3x - 5 one unit to the right, we substitute x with (x - 1) because subtracting from the independent variable moves the graph to the right.
The translated expression is y = 3(x - 1) - 5, which simplifies to y = 3x - 3 - 5 or y = 3x - 8.
The process of translating graphs involves shifting each point parallel to the x-axis, either to the left or right, by the desired number of units without altering the shape of the graph.

C. 226.8 ft2
D. 631.8 ft2
Answer:
B. 140.4 square feet.Step-by-step explanation:
If all faces are equilateral, and they are all congruent, that means the surface area of the pyramid is formed by 4 equal triangles, including the base.
We just need to find the area of one triangle and then multiply it by 4.
According to the image, the height of a triangle face is [tex]h=7.8 \ ft[/tex], and its base is [tex]b=9 \ ft[/tex]. So, the area is
[tex]A=\frac{1}{2} (b \times h)[/tex]
[tex]A=\frac{1}{2}(7.8 \times 9) =35.1 \ ft^{2}[/tex]
Then, the total surface area of the pyramid is
[tex]S=4(35.1)=140.4 \ ft^{2}[/tex]
Therefore, the right answer is B. 140.4 square feet.

an element with a mass of 540 grams decays by 17.9% per minute to the nearest tenth of a minute how long will it be until there are 90 grams of the element remainibg
Answer:
It'll take approximately 9.1 minutes
Step-by-step explanation:
The decay of this element can be modeled by the following expression:
m(t) = 540*(1 - 0.179)^t
Where m is the mass of the element in a given minute t. This expression comes from a compounded interest formula, with negative rate, since they will work in the same manner. Therefore to find how long until it reaches 90 g, we need to make m = 90 and solve for t.
90 = 540*(0.821)^t
(0.821)^t = 90 / 540
(0.821)^t = 1/6
ln(0.821^t) = ln(1/6)
t*ln(0.821) = ln(1) - ln(6)
t*ln(0.821) = - ln(6)
t = -ln(6)/ln(0.821) = 9.08452
It'll take approximately 9.1 minutes
