Answer:
244 cm³
Step-by-step explanation:
Step 1: Given data
Height of the prism with a pentagonal base (h): 8 cm
Area of the pentagonal base (A): 30.5 cm²
Step 2: Calculate the volume of the prism with a pentagonal base
We have a regular pentagonal prism, that is, the 5 sides of the base are equal and we know the area of the base and the height of the prism. We can calculate its volume using the following expression.
V = A × h
V = 30.5 cm² × 8 cm = 244 cm³
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:
-45 =x
Step-by-step explanation:
1/5(4x-2.5) = 5(.4x+10) +3 1/2
Change all to decimal form
.2(4x-2.5) = 5(.4x+10) +3.5
Distribute
.8x - .5 = 2x +50 + 3.5
Combine like terms
.8x - .5 = 2x +53.5
Subtract .8x from each side
.8x-.8x - .5 = 2x-.8x +53.5
-.5 = 1.2x +53.5
Subtract 53.5 from each side
-.5 -53.5 = 1.2x +53.5-53.5
-54 = 1.2x
Divide each side by 1.2
-54/1.2 = 1.2x /1.2
-45 =x
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

(PLEASE HELP) 17. Jon read 3/8 of a book the
first day. 1/3 the second day.
and 1/4 the third day. On the
fourth day he finished the book.
What part of the book did Jon
read on the fourth day?
Answer:
[tex]\frac{1}{24}[/tex]
Step-by-step explanation:
24 is a common multiple so ill just use that as a denominator:
3/8 = 9/24
1/3 = 8/24
1/4 = 6/24
so then adding those up:
[tex]\frac{9}{24}[/tex] + [tex]\frac{8}{24}[/tex] + [tex]\frac{6}{24}[/tex] = [tex]\frac{23}{24}[/tex]
then whats left is 1/24 left to read, which cant be simplified so [tex]\frac{1}{24}[/tex]
Answer:
[tex]\frac{1}{24}[/tex]
Step-by-step explanation:
Let x be the part of the book he read on fourth day.
[tex]\frac{3}{8} + \frac{1}{3} + \frac{1}{4} + x = 1[/tex]
[tex]LCM \ of \ 8, 3 , 4 = 24.\ Therefore , \\\\[/tex]
[tex]\frac{3}{8} + \frac{1}{3} + \frac{1}{4} + x = 1\\\\\frac{9 + 8 + 6 + 24x}{24} = 1\\\\23 + 24x = 24\\24x = 1\\x = \frac{1}{24}[/tex]
[tex]On\ the\ fourth\ day\ he\ read\ \frac{1}{24} \ of\ the\ book\ to\ finish\ it.[/tex]
What is the area of this triangle?
What is the length of the hypotenuse of the triangle when x=11?
Answer:
hypotenuse = 93.06
Step-by-step explanation:
[tex]x = 11\\\\base = 4 \times 11 = 44\\\\height = 7x + 5 = 7 \times 11 + 5 = 77 + 5 = 82\\\\hypotenuse ^2 = base^2 + height^2\\[/tex]
[tex]=44^2 + 82^2\\\\=8660[/tex]

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.

Answer:
75.4
Step-by-step explanation:
All angles in a triangle should equal 180, so the lil dash on K's side means angle K is the same as J
so 52.3+52.3=104.6
and 180-104.6 is 75.4

An article is bought for Rs 8600 and is sold at a profit of 20 %. Find its selling price.
Selling price = 8600 + Profit
Selling price = 8600 + ( 8600 × 20/100 )
Selling price = 8600 + ( 86 × 20 )
Selling price = 8600 + 1720
Selling price = Rs 10,320

A tool box has the dimensions of 10 in by 4 in by 7 in. If Magnus plans to double all three dimensions to build a larger tool box, he believes he would double the volume of the tool box. Is he correct?
Answer: No. He's wrong.
Step-by-step explanation:
Since the tool box has the dimensions of 10 in by 4 in by 7 in. The volume will be:
= 10 × 4 × 7
= 280in³
When the dimensions are doubled, the new dimensions will be:
10 in = 10in × 2 = 20in
4in = 4in × 2 = 8 in
7in = 7in × 2 = 14in
The volume will now be:
= 20 × 8 × 14
= 2240in³
He is wrong, the volume isn't the double of the former tool box. The double of the former tool box will give (280in³ × 2) = 560in³. This is different from the new volume.

The Martinez family picked 3 lb of apples. Ana picked for those apples,
How many pounds of apples did Ana pick?
Answer:
C. 7/8
Step-by-step explanation:
The Martinez family picked 3 and one-half pounds of apples. Ana picked one-fourth of those apples. How many pounds of apples did Ana pick?
options
A. 1/4
B. 3/4
C. 7/8
D. 1 1/4
E. 3 1/8
Total apples the Martinez family picked = 3 1/2 pounds
Ana picked one-fourth of those apples.
Number of apples Ana picked = 1/4 × 3 1/2 pounds
= 1/4 × 7/2 pounds
= (1 * 7) / (4 * 2) pounds
= 7/8 pounds
Ana picked 7/8 pounds of apples

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
