What is the surface area of the right triangular prism below?
Answer:
[tex]A=189\ mm^2[/tex]
Step-by-step explanation:
Surface Areas
Is the sum of all the lateral areas of a given solid. We need to compute the total surface area of the given prism. It has 5 sides, two of them are equal (top and bottom areas) and the rest are rectangles.
Computing the top and bottom areas. They form a right triangle whose legs are 4.5 mm and 6 mm. The area of both triangles is
[tex]\displaystyle A_t=2*\frac{b.h}{2}=b.h=(4.5)(6)=27 mm^2[/tex]
The front area is a rectangle of dimensions 7.7 mm and 9 mm, thus
[tex]A_f=b.h=(7.5)(9)=67.5 \ mm^2[/tex]
The back left area is another rectangle of 4.5 mm by 9 mm
[tex]A_l=b.h=(4.5)(9)=40.5 \ mm^2[/tex]
Finally, the back right area is a rectangle of 6 mm by 9 mm
[tex]A_r=b.h=(6)(9)=54 \ mm^2[/tex]
Thus, the total surface area of the prism is
[tex]A=A_t+A_f+A_l+A_r=27+67.5+40.5+54=189\ mm^2[/tex]
[tex]\boxed{A=189\ mm^2}[/tex]

A rectangular piece of metal is 25 in longer than it is wide. Squares with sides 5 in long are cut from the four corners and the flaps are folded upward to form an open box. If the volume of the box is 2730 in^3, what were the original dimensions of the piece of metal?
Answer:24 oringal width
49 original length
Step-by-step explanation:
The original dimensions of the rectangular piece of metal were 30 inches by 55 inches, based on the given conditions of making an open box and its volume.
Explanation:In this problem, we have a rectangular piece of metal that is being converted into an open box. Note that the length of the rectangular piece is 25 in longer than its width.
When squares with side 5 in are cut from the corners and the sides are folded up to make the open box, the dimensions of the box formed become length = w+25-10, width = w-10, and height = 5, where w is the width of the original rectangular piece.
The volume of a box is given by the product of length, width, and height. So if the volume of this box is given as 2730 cubic inches, we can write the equation (w-10)(w+15)(5)=2730.
This can be solved to give w=30 (excluding the negative solution as unrealistic for this context). Therefore, the original dimensions of the metal piece were 30 in (width) by 55 in (length).

What is the slope of the line that is perpendicular to the line that passes through (-2, 7) and (4, 9)? Type a numerical answer in the space provided.
Answer:
Therefore [tex]m_{2}[/tex] = -3.
Step-by-step explanation:
i) let us say the slope of the line passing through (-2,7) and (4,9) is [tex]m_{1}[/tex].
ii) to find the slope of the line passing through two points ([tex]x_{1}[/tex], [tex]y_{1}[/tex]) and ([tex]x_{2}[/tex],[tex]y_{2}[/tex]) we use the formula m = [tex]\dfrac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]. Therefore we can say that [tex]m_{1}[/tex] = [tex]\dfrac{9 - 7}{4 - (-2)}[/tex] = [tex]\dfrac{1}{3}[/tex].
iii) let us say the slope of the perpendicular line to the line passing through (-2,7) and (4,9) is [tex]m_{2}[/tex]
iv) from the formula for the slopes of a line and the line perpendicular to it which is given by [tex]m_{1}[/tex] × [tex]m_{2}[/tex] = -1, therefore [tex]m_{2}[/tex] = -1 ÷ [tex]m_{1}[/tex] = -3. Therefore [tex]m_{2}[/tex] = -3

y = 2x + 7
y = -2x - 5
I have been trying to figure it out but idk.
Answer:
The values for the two equations are x=-3 and y=1
Therefore the solution is (-3,1)
Step-by-step explanation:
Given equations are [tex]y=2x+7\hfill (1)[/tex]
[tex]y=-2x+5\hfill (2)[/tex]
To solve the given equations by Substitution method :
We are using here to solve the given equations by Substitution method because equations (1) and (2) are equivalent ( it has same solution )
Therefore we can equate the two given equations or substitute the y value equation (1) in (2) we get
2x+7=-2x-5
Subtracting with -(2x-5) on both sides we get
2x+7-(-2x-5)=-2x-5-(-2x-5)
2x+7+2x+5=-2x-5+2x+5
4x+12=0 ( adding the like terms )
4x=-12
[tex]x=-\frac{12}{4}[/tex]
Therefore x=-3
Now substitute the value x=-3 in equation (1) we get
y=2(-3)+7
y=-6+7
Therefore y=1
The values are x=-3 and y=1
The solution is (-3,1)

what is the final elevation if a driver starts at 5 m and changes -16 m?
Answer:
- 11 m elevation.
Step-by-step explanation:
The driver starts at an elevation of 5 m and he drives to get a change in elevation by - 16 m.
There is no doubt that the driver drives down to the negative elevation.
So, the driver first reaches the zero elevation then drives towards negative elevation.
Now, the final elevation of the driver will be at (5 - 16) m = - 11 m. (Answer)

Joe is going to rent a truck for one day.company A has no initial fee but charges 80 cents for every mile driven. Company B charges an initial fee of $50 and an additional 60 cents for every mile driven.for what mileage will company A charge more than company B?
Answer:
Therefore the minimum mileage for which Company A will charge more than Company B is 251 miles.
Step-by-step explanation:
i) let x be the number of miles driven
ii) If Joe rents the truck from Company A the Joe will pay Company A
= $0.8x
iii) If Joe rents the truck from Company B then Joe will pay Company B
= $50 + $0.6x
iv) the mileage for which the rents of both companies will be equal is given by
$0.8x = $50 + 0.6x
Therefore 0.2x = $50
Therefore x = [tex]\frac{50}{0.2} = \frac{500}{2} = 250[/tex] miles.
Therefore the minimum mileage for which Company A will charge more than Company B is 251 miles.
Factor the following trinomials:
a) x^2 -2x -1
b) x^2 -3x+1
Final answer:
To factor the trinomials x^2 - 2x - 1 and x^2 - 3x + 1, you can use the quadratic formula or factoring by grouping.
Explanation:
To factor the trinomials x^2 - 2x - 1 and x^2 - 3x + 1, we can use the quadratic formula or factoring by grouping.
a) For x^2 - 2x - 1, we can use the quadratic formula:
x = (-b ± sqrt(b^2 - 4ac))/(2a)
Plugging in the values, we have:
x = (-(-2) ± sqrt((-2)^2 - 4(1)(-1)))/(2(1))
x = (2 ± sqrt(4 + 4))/(2)
x = (2 ± sqrt(8))/(2)
x = (2 ± 2sqrt(2))/(2)
x = 1 ± sqrt(2)
Therefore, the factored form is: x^2 - 2x - 1 = (x - (1 + sqrt(2)))(x - (1 - sqrt(2)))
b) For x^2 - 3x + 1, we can also use the quadratic formula:
x = (3 ± sqrt(3^2 - 4(1)(1)))/(2(1))
x = (3 ± sqrt(5))/(2)
Therefore, the factored form is: x^2 - 3x + 1 = (x - (3 + sqrt(5))/(2))(x - (3 - sqrt(5))/(2))
a) x^2 - 2x - 1 = (x - 1)(x + 1)
b) x^2 - 3x + 1 = (x - 1)^2
a) x^2 - 2x - 1:
This trinomial is in the form ax^2 + bx + c. To factor it, we need to find two numbers that:
Multiply to ac (in this case, 1 * -1 = -1).
Add up to b (in this case, -2).
These two numbers are -1 and 1.
So, we can rewrite the trinomial as:
(x - 1)(x + 1)
Therefore, the factored form of x^2 - 2x - 1 is (x - 1)(x + 1).
b) x^2 - 3x + 1:
This trinomial is also in the form ax^2 + bx + c. To factor it, we need to find two numbers that:
Multiply to ac (in this case, 1 * 1 = 1).
Add up to b (in this case, -3).
These two numbers are -1 and -1.
So, we can rewrite the trinomial as:
(x - 1)(x - 1)
However, it is common practice to simplify repeated factors, so the fully factored form of x^2 - 3x + 1 is (x - 1)^2.

Step-by-step explanation:
4/9 is it equivalent to 20/36
Answer: No
Step-by-step explanation: In order to decide whether the given fractions are equivalent, first write each fraction in lowest terms.
A fraction is written in lowest terms if the greatest common factor of the numerator and the denominator is 1.
So for our first fraction, 4/9, since the greatest common factor of 4 and 9 is 1, we know that are fraction is already written in lowest terms.
For our second fraction however, since the greatest common factor of 20 and 36 is 4, we must divide both the numerator and the denominator by 4 to write our fraction in lowest terms. This gives us 5/9.
Since 5/9 is bigger than 4/9, te fractions are not equivalent so no, 4/9 is not equivalent to 20/36.
A campus apartment has two bedrooms and two attached bathrooms and rents for $1,025 per month plus an average of $60 per month for electricity. You are a student and would have the option of splitting the rent with a fellow student 60/40. You pay 40% as your name is on the lease. Your scholarship gives you $700 per month for housing. What can you save above your out of pocket housing cost with your scholarship and your roommate's contribution in an Academic Year (8 months).
I can save $2,128 in my academic year and my roommate can save $392 in their academic year.
Step-by-step explanation:
Total housing amount= rent + electricity= $1,025 + $60= $1,085 per month
My rent is 40% of $1,085 which equals $434 a month while my roommate’s rent would be 60% of $1,085 which equals $651 a month.
The scholarship gives me $700 a month for housing out of which I spend $434 and my roommate spends $651.
I save; $700 - $434 = $266 a month
My roommate saves; $700 - $651 = $49 a month.
An academic year lasts for 8 months so my savings= $266 x 8 = $2,128
My roommate’s savings= $49 x 8 = $392
Answer:
$2,128
Step-by-step explanation:
Expenses is allocated based on the decided ratios. Expenses and Inflows
Expenses will be calculated for 8 Months time period.
Rent = 1,025 x 8 months = $8,200
Electricity Expense = $60 x 8 = $480
Total Expense = $8,200 + $480 = $8,680
Total Scholarship = $700 x 8 = $5,600
Out of Pocket Cost = $8,680 x 40% = $3,472
Saving is the difference between The scholarship received and the Expenses made from pocket.
Saving = $5,600 - $3,472 = $2,128

Sarah has a collection of nickels, dimes, and quarters worth $9.25. She has 10 more dimes than nickels and twice as many quarters as dimes. How many coins of each kind does she have?
Answer:
See image attached.
Step-by-step explanation:
Final answer:
The initial setup for the equation based on the coin values and the total amount led to an incorrect result with a negative number of nickels. This suggests there was an error in the calculations or assumptions, and the equation should be revisited and the numbers checked to find the correct number of each type of coin.
Explanation:
Let's call the number of nickels Sarah has n. According to the problem, Sarah has 10 more dimes than nickels, which means she has n+10 dimes. It is also given that she has twice as many quarters as dimes, making it 2(n+10) quarters. In terms of their values, nickels are worth 5 cents, dimes are worth 10 cents, and quarters are worth 25 cents. The total value of Sarah’s coins is $9.25, which is equivalent to 925 cents.
To find the number of each coin, we can set up the following equation:
5n + 10(n+10) + 25(2(n+10)) = 925
Simplifying the equation:
5n + 10n + 100 + 50n + 1000 = 925
65n + 1100 = 925
65n = 925 – 1100
65n = -175
n = -175 / 65
n = -2.6923
This result is not possible since we cannot have a negative number of coins. It seems there was an error in the calculations or assumptions. It is important to check the equation and numbers we're using to ensure they properly represent the coin values and the total amount.
What is the answer to 5% of $30
Answer: $1.50
Step-by-step explanation: To find 5% of $30, first write 5% as a decimal by moving the decimal point 2 places to the left to get .05. Next, "of $30" means times 30 so we multiply .05 times 30 which gives us 1.5.
Finally, remember that we want to write our answer in terms of dollars so 1.5 dollars is the same thing as $1.50.
So 5% of $30 is $1.50.
