Answer:
The interest rate is 20%.
Step-by-step explanation:
In order to calculate the interest rate, we need to compute how many percents the value he recieves is related to the total he invested. In this case he recieves 40 every year and he invested 200, to calculate that we will apply a rule of three. We have:
$200 -> 100%
$40 -> x%
200/40 = 100/x
200*x = 40*100
200*x = 4000
x = 4000/200 = 20
The interest rate is 20%.

When trying to find solutions to the system of equations x+y=3 2x+2y=6 you take several correct steps that lead to the expression 0=0. Which statement is true?
Answer:
They are the same equations. (I don't know what you mean by "true.")
Step-by-step explanation:
If you divide 2x + 2y = 6 by 2, it turns into x + y = 3. This means that the graphs of the lines are the same, or there are infinite solutions.
I am really sorry if this is wrong because I am not really sure what you meant by "Which statement is true?"
A cylinder has a radius of 2 meters and a height of 10 meters. What is the volume of the cylinder? Cylinder V = Bh 1. Write the formula replacing B with the formula for the area of a circle: 2. Substitute the actual measures for the variables: 3. Evaluate the power: V = πr2h V = π(22)(10) V = π(4)(10) 4. Simplify: V = π m3
Answer:
125.6 cubic meters
Step-by-step explanation:
To calculate the volume of the cylinder, we will do it as follows:
Vc = Base area * Height
We know that the base of the cylinder is a circle, therefore:
Base area: pi * r ^ 2
replacing we have:
Vc = pi * (r ^ 2) * h
We have r = 2 and h = 10, we replace:
Vc = pi * (2 ^ 2) * 10
Vc = 40 * pi
pi = 3.14
Vc = 40 * 3.14
Vc = 125.6
Which means that the volume of the cylinder is 125.6 cubic meters

Find the volume of a pyramid with a square base, where the area of the base is
8.7 m and the height of the pyramid is 10 m. Round your answer to the nearest
tenth of a cubic meter.
Answer: 29.0
Step-by-step explanation:
The volume of a pyramid is equal to l*w*h/ 3 and we know that the length times the width is the same as the base.
so we will multiply 8.7 * 10= 87 /3= 29
Volume = 87 m³
You need to multiply the area and the height to find the volume. If you have the length, width, and height, then you need to multiply and 3 and divide it by 3. Hope I helped :)

Find the area of the shaded triangle
Area of a triangle is 1/2 x base x height.
The base of the shaded triangle is 2 ft. the height is 4 ft.
Area = 1/2 x 2 x 4 = 4 square feet.
Answer:
4 ft²
Step-by-step explanation:
A = 1/2bh Use this equation to find the area of the triangle
A = 1/2(4)(4) Multiply
A = 1/2(16) Multiply
A = 8 Area of entire triangle
A = 1/2(2)(4) Multiply
A = 1/2(8) Multiply
A = 4 Area of triangle not shaded
Take the area of the whole triangle minus the area of the unshaded part
8 - 4 = 4 ft²

Given the information below, write the conclusion in context. 1. H0 : The proportion of defective batteries = 0.02 2. HA : The proportion of defective batteries < 0.02 3. Z-score of observed sample = −1.23
Answer:
[tex] z = -1.23[/tex]
And we can calculate the p value with the following probability taking in count the alternative hypothesis:
[tex] p_v = P(z<-1.23) = 0.1093[/tex]
And for this case using a significance level of [tex]\alpha=0.05 ,0.1[/tex] we see that the p value is larger than the significance level so then we can conclude that we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true proportion is less than 0.02
Step-by-step explanation:
For this case we want to test the following system of hypothesis:
Null hypothesis: [tex]p =0.02[/tex]
Alternative hypothesis: [tex] p < 0.02[/tex]
The statistic for this case is given by:
[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)
And for this case we know that the statistic is given by:
[tex] z = -1.23[/tex]
And we can calculate the p value with the following probability taking in count the alternative hypothesis:
[tex] p_v = P(z<-1.23) = 0.1093[/tex]
And for this case using a significance level of [tex]\alpha=0.05 ,0.1[/tex] we see that the p value is larger than the significance level so then we can conclude that we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true proportion is less than 0.02

Farrah is making a dragon costume for her little brother. It would have triangular spikes down the head and back each head spike has a base of 2 centimeters and a height of 6 cm each box pies will be 10 centimeters high with a base of 6 in the costume of 6 specs on the head + 10 more spice than the back how many square centimeters of fabric will far are we need for all the dragon spikes
The question is not written properly! Complete question along with answer and explanation is provided below.
Question:
Farrah is making a dragon costume for her little brother. It would have triangular spikes down the head and back.
Each head spike has a base of 2 cm and a height of 6 cm.
Each back spike will be 10 cm high with a base of 6 cm.
if the costume has 6 spikes on the back and on the head 10 more spikes than the back then how many square centimeters of fabric will farrah need for all the dragon spikes?
Given Information:
Base of head spike = b₁ = 2 cm
Height of head spike = h₁ = 6 cm
Base of back spike = b₂ = 6 cm
Height of back spike = h₂ = 10 cm
Number of head spikes = n₁ = 10 + 6 = 16
Number of back spikes = n₂ = 6
Required Information:
How much fabric is needed = ?
Answer:
Farrah would need 276 cm² of fabric for all the dragon spikes.
Step-by-step explanation:
We are given that dragon costume have triangular spikes down the head and back.
The area of triangular shape is given by
Area = ½×b×h
Where b is the base and h is the height
The area of the head spike is
A₁ = ½×b₁×h₁
A₁ = ½×2×6
A₁ = ½×12
A₁ = 6 cm²
But we know that the number of head spikes is 16 so the total area of the head spikes is
A₁ = 16×6
A₁ = 96 cm²
The area of the back spike is
A₂ = ½×b₂×h₂
A₂ = ½×6×10
A₂ = ½×60
A₂ = 30 cm²
But we know that the number of back spikes is 6 so the total area of the back spikes is
A₂ = 6×30
A₂ = 180 cm²
The total area required is the sum of the area of head spikes and back spikes,
Total area = A₁ + A₂
Total area = 96 + 180
Total area = 276 cm²
Therefore, Farrah would need 276 cm² of fabric for all the dragon spikes.

Circle Q is centered at the origin and has a radius of 9 units. which equation could represent circle Q
Answer:
x^2 + y^2 = 81
Step-by-step explanation:
Mathematically, the equation of a circle can be represented by ;
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center of the circle which is the origin in this case. The origin has the coordinates (0,0)
the radius here is 9 units
Thus, the equation of the circle would be;
(x-0)^2 + (y-0)^2 = 9^2
= x^2 + y^2 = 81

The function f(x)=200/x + 10 models the cost per student of a field trip when x students go on the trip. How is the parent function f(x)=1/x transformed to create the function f(x)=200/x + 10
Answer:
Step-by-step explanation:
We need to explain the transformations applied to 1/x to get f(x). We get f by following the following steps.
1. Multiply 1/x by 200 to get the function 200/x. This represents taking the graph of 1/x and expanding it vertically by a factor of 200.
2. Sum 10 units to 200/x. This represents a vertical shift of 10 units to the graph of 200/x.

Maris put trim around a mirror that is the shape of a square. Each side is 24 inches long. Maria has 1 foot of trim left. What was the length of the trim when she started? Write your answer in yards
Answer:
16.028 yards
Step-by-step explanation:
1 inch=0.0833333 foot
24 inches=0.0833333×24
=1.9999992 foot
The mirror is square shaped and each side is 24 inches
If each 24 inches=1.9999992 foot
Then,
4 sides of 24 inches=1.9999992×24
=47.9999808 foot
Maria has 1 foot of trim left
Total Length of trim when she started=47.9999808+0.0833333
