Determine the length of the radius of the circumscribed circle to the right triangle with the legs 7 cm and 4cm.Round your answer to the nearest hundredth
Answer:
4.03cm
Step-by-step explanation:
Note that the diameter of the circumscribed circle to the right triangle is the hypotenuse of the triangle.
To get the diameter, we will use the pythagoras theorem as shown;
d² = 7² + 4²
d² = 49 + 16
d² = 65
d = √65
d = 8.0622577
Since radius = d/2
radius = 8.0622577/2
radius = 4.0311288
Hence the radius of the circumscribed circle to the nearest hundredth is 4.03cm
17. Jing has $800 to deposit into two different savings accounts.
•She will deposit $600 into an account that earns simple interest annually at a rate
of 2.75%.
•She will deposit $200 into an account that earns 2.5% interest compounded
annually.
Jing will not make any additional withdrawals or deposits. Which amount is closest
to the total balance of the two accounts at the end of 3 years?
Answer:
$864.88
Step-by-step explanation:
(1. $600 + $49.50 = $649.50
(2. $200 + $15.38 = $215.38
$649.50 + $215.38 = $864.88
A = $864.88

Step-by-step explanation:
A playground has two sandboxes. Each sandbox is in the shape of a right prism. The first sandbox has a square base with a side length of 8 feet. What is the area, in square feet, of the base of the first sandbox? Show or explain how you got your answer. Help
Answer:
64 ft²
Step-by-step explanation:
A prism is a three dimensional shape with two identical shapes facing each other known as bases. A right prism is a three dimensional solid with a polygon as its base and vertical sides which are perpendicular to the base.
Given that the first sandbox is a right prism a square base, hence this is a square prism (that is a cube).
Since the side length of the square base is 8 ft, hence the area of the base of the first sandbox is:
Area of the base = length * length = 8 ft * 8 ft = 64 ft²

Of six Kokomuka (Hebe Elliptica) seedlings, four have survived the winter.
What percentage of the seedlings survived?
Answer:
66.7%
Step-by-step explanation:
The number of seedlings planted is 6, while the number of seedlings that survived the winter is 4. Therefore the percentage of seedlings that survived can be gotten using the formula:
Percentage of seedlings survived = (survived seedlings / total seedlings planted) * 100%
Therefore substituting values gives:
Percentage of seedlings survived = (4 / 6) * 100% = 66.7%

Now that you know how long it will take to buy your house from Assignment 4 and how much you need to save for retirement given different start times in your life (Assignment 5), you will now determine the time you will start saving for retirement. Add the savings time it takes to buy your house (2 years or the months you calculated, whichever is greater) to the age 22. By using the new budget from assignment 4, determine if you can afford the savings it takes from assignment 5 to retire with $1,000,000 based on your new age after buying your house. If you cannot, you have a choice, change your budget, or retire will less money.
For your answer, tell me your age, if you can afford in your budget to retire with $1,000,000. If you can, write your budget with the retirement savings added in. If you cannot, write that you cannot afford it and tell me if you are going to change your budget to afford it or simply retire with less money. Then write your budget with what savings you can afford. Remember, retiring with less money does not mean that you will have a smaller retirement income, it just means that you will pass on less than a million dollars to your children.

Answer:
Carole's situation : 2x + 11y = 196
Michele's situation: 10x + 11y = 276
Step-by-step explanation:
If x = cost of 1 cupcake, then 2x = cost of 2 cupcakes and 10x = cost of 10 cupcakes, et.
If y = cost of 1 sugar cookie, then 11y = cost of 11 sugar cookies.
Carole's situation : 2x + 11y = 196
Michele's situation: 10x + 11y = 276

the table shows some of the solutions for an inequality related to the line shown in the graph. which inequality describes the solution set?
Answer:
Option B
Step-by-step explanation:
By plotting the points given in the table,
All points lie below the dark red line.
Let the equation of the line is,
y - y' = m(x - x')
Here, m = Slope of the line
(x', y') is a point lying on the given line.
Slope of the line passing through two points (-1, 3) and (0, 1) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{3-1}{-1-0}[/tex]
m = -2
Therefore, equation of the line passing through (0, 1),
y - 1 = -2(x - 0)
y = -2x + 1
Since all the points given in the table lie below the dark red line so the solution are will be,
y ≤ -2x + 1
Option B will be the correct option.
A circle of radius 1 is inside a circle of radius 5. The smaller circle is rotated clockwise
on the larger circle without slipping until it arrives back at its starting point P. How
many revolutions (turns) will the small circle make? Be careful. The answer is not 5.
9514 1404 393
Answer:
4
Step-by-step explanation:
Consider the arcs PQ and P'Q. When turns are made without slipping, these have the same measure. The length of arc PQ is ...
PQ = CP·θ
The length of arc P'Q is ...
P'Q = O₂Q·(∠PO₂Q)
Segment O₂A is parallel to CP, so angle AO₂Q is θ. Then ∠PO₂Q = θ+α, where α is the angle by which P' has rotated counterclockwise from A.
We are given that ...
CP = 5, O₂Q = 1
Using the above relations, we can write ...
5θ = 1(θ+α)
α = 4θ
That is, for every full turn θ = 2π, the smaller circle makes turns totalling 4(2π) = 8π, or 4 full turns.
The small circle makes 4 revolutions to arrive at its starting point.

Answer:
1) m<DBE= 140
2)m<EBD= 30
Step-by-step explanation:
1) 5x-60= x+20
4x= 80
x= 20
plug in the x into the equation: (x+20)---> (20+20)=40
180-40= 140
2) 4x-2+20x-10= 180
24x= 192
x=8
plug in the x into the equation: (4x-2)----> 4(8)-2----> 32-2= 30

Look at the picture. Solve for y
Answer:
y = 5
Step-by-step explanation:
Equation:
m<DGF = m<DGE + m<EGF
Given:
m<DGF = 12y - 5
m<DGE = 5y + 6
m<EGF = 24
Work:
m<DGF = m<DGE + m<EGF
12y - 5 = 5y + 6 + 24
12y - 5 = 5y + 30
12y - 5y = 30 + 5
7y = 35
y = 5
