An art exhibit is made by stacking three identical prisms on top of each other end-to-end so their smallest faces overlap. One of the prisms is shown here.
Find the surface area of the total exhibit.
The surface area of the exhibit is 1,638 cubic inches.
Step-by-step explanation:
Step 1:
If three prisms are out on top of each other we get a shape as follows;
The length of the base [tex]= 9[/tex] inches,
The width of the base [tex]=6[/tex] inches, and
The height of the exhibit [tex]= 3(17) = 51[/tex] inches.
To find the surface area of the total exhibit we consider there to be only one shape which the above dimension.
Step 2:
There are 6 faces to the exhibit.
The surface area of a rectangular prism is given by;
[tex]A=2(w l+h l+h w)[/tex]
By substituting the values, we get
[tex]A=2((6)(9)+(51) (9)+(51) (6)) = 2 (819) = 1,638.[/tex]
The surface area of the exhibit is 1,638 cubic inches.

The queen had 300 servants. there were 10 more butlers than cooks. the number of cooks was twice the number of maids. how many maids worked at the queen palace?
The no. of maids who worked at the queen's palace is 58.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, The queen had 300 servants. there were 10 more butlers than cooks. The number of cooks was twice the number of maids.
Assuming the no. of maids to be 'x', therefore no. of cooks is 2x and the no. of butlers is (2x + 10).
∴ x + 2x + (2x + 10) = 300.
5x = 290.
x = 58.

1. Luis made a $150 bank deposit using $5 bills and $10 bills. He gave the teller a total of 24
bills. How many $10 bills were in the deposit?
1st equation:
2nd equation:
What did you have to multiply the first equation by, if anything?
What did you have to multiply the second equation by, if anything?
Answer:
cils Gabby bought a nens and Spencils
6 bills in the deposit were $10 bills.
Step-by-step explanation:
The total number of bills he gave the teller = 24 bills
x + y = 24 ------------(1)
Let,
x be the number of $5 bills.
y be the number of $10 bills.
The total bank deposit made using $5 and $10 bills are $150.
He deposits $5 bills and $10 bills. So, the equation can be framed as :
5x + 10y = 150 --------(2)
The question is asked for how many $10 bills were in the deposit,
Here 'y' is the number of $10 bills.
To solve for y value :
The eq(1) must be multiplied by 5 and subtract eq(2) from eq(1),
5x + 5y = 120
-(5x + 10y = 150)
-5y = -30
⇒ y = 30/5
⇒ y = 6
Therefore, there were 6 bills in the deposit that are $10 bills.

Write the explicit formula for the geometric sequence
The formula [tex]3(4^{n-1})[/tex] represents the geometric sequence.
Step-by-step explanation:
Step 1:
The value of [tex]a_{n}[/tex] is dependent on the value of n.
So n is independent while [tex]a_{n}[/tex] is dependent on n i.e. the value of [tex]a_{n}[/tex]depends on the value of n.
Step 2:
We substitute the values of n in the functions to check which function satisfies the values of [tex]a_{n}[/tex].
If [tex]n = 4, a_{n} = -4(3)^{n-1} = -4 (3^{3}) = -108.[/tex] This does not equal the value of [tex]a_{n}[/tex].
If [tex]n = 4, a_{n} = 4(3)^{n-1} =-4 (3^{3}) = 108.[/tex] This does not equal the value of [tex]a_{n}[/tex].
If [tex]n = 4, a_{n} =3(-4)^{n-1} = 3 (-4^{3}) = -192.[/tex] This does not equal the value of [tex]a_{n}[/tex].
If [tex]n = 4, a_{n} =3(4)^{n-1} = 3 (4^{3}) = 192.[/tex] This equals the value of [tex]a_{n}[/tex].
So the fourth formula represents the geometric sequence.

Answer:
The radius is 2.5 yards
The diameter is 5 yards
Step-by-step explanation:
We want to find the radius and diameter given that, the circumference of the circle is;
C=5π yards.
Recall that, the circumference of a circle is C=πd
This implies that:
[tex]5\pi = \pi \: d[/tex]
Divide both sides by π
[tex]5 = d[/tex]
To find the radius, divide the diameter by 2;
[tex]r = \frac{5}{2} = 2.5[/tex]
The radius is 2.5 yards
The diameter is 5 yards
Area of circles

[tex]area \: of \: bottom \: of \: pool \\ = \pi {r}^{2} \\ = 3.14 \times ( {12.5)}^{2} \\ = 3.14 \times 156.25 \\ = 490.625 \: {m}^{2} \\ \approx490.63 \: {m}^{2} [/tex]
marco wants to buy 2 books that cost 20$ each. He can save $5 a week. Draw siagrama and write equations to find how many weeks it will take hime to save enough money to buy the books.
Answer: He needs to wait 8 weeks.
Step-by-step explanation: 5•8 equals 40. 2 books, 20$ each and add them together, 40!
To determine the number of weeks Marco needs to save $40 to buy two books at $20 each, an equation can be set up based on his weekly savings of $5. Solving the equation 5 × w = $40 gives us w = 8, meaning Marco will need to save for 8 weeks.
Explanation:The problem given is about Marco who wants to buy two books, each costing $20. He can save $5 a week. To calculate how many weeks it will take for Marco to save enough to buy the books, we can set up an equation. First, we need to determine the total cost of the books:
Cost of one book = $20Cost of two books = 2 × $20 = $40Next, let’s set up our equation. If Marco saves $5 each week, the total amount saved after w weeks will be 5 × w. We want this to be equal to the total cost of the books, so our equation will be:
5 × w = $40
To solve for w, we divide both sides by 5:
w = $40 / 5
w = 8
Therefore, it will take Marco 8 weeks to save enough money to buy the two books.
The Strike Zone Battling Center provides cages for baseball players to perfect their swing. The patron pays a fixed rate of $12.75 for the first 45 minutes, pay an additional $0.35 for up to two hours and $0.25 per minute for any additional time over two hours. The following function is used to compute the overall cost for a patron.
where x is the amount of time in minutes spent battling at the Strike Zone. How much would you pay for 115 minutes?
To calculate the cost for 115 minutes at the Strike Zone Battling Center, we account for the flat rate for the first 45 minutes and add the additional cost for the remaining 70 minutes at a rate of $0.35 per minute. We find that the total would be $37.25.
Explanation:The cost calculation for using the cages at the Strike Zone Battling Center operates on a tier system. The first 45 minutes costs a flat rate of $12.75. If a patron uses it for additional time up to 2 hours (or 120 minutes), it's an extra $0.35 per minute. Anything over 2 hours is $0.25 per minute.
To calculate the cost for 115 minutes, we determine that it is less than 2 hours. Therefore, the cost will be the flat rate of $12.75 plus the additional cost for 70 minutes (which is 115 minutes minus the first 45 minutes) at $0.35.
The calculation goes as follows:
$12.75 + (70 * $0.35) = $12.75 + $24.50 = $37.25.
So, for 115 minutes, you would pay $37.25
