Gabriel wants to paint the model. How
much paint will he need?
The area of the square base is in.?
The area of each triangular face is
in.
Gabriel will need in.2 of paint.
Answers
Answer:
The area of the base is 144 square inches.The area of each triangular face is 66 square inches.Grabiel needs 408 square inches of paint.Step-by-step explanation:
The complete problem is attached.
Notice that the figure is a square pyramid, where its base dimensions are 12 inches by 12 inches, which represents an area of
\(B=12 \times 12 = 144 \ in^{2}\)
The slant height of the pyramid is 11 inches, which allow us to find the area of each triangle face
\(A=\frac{1}{2}bh =\frac{1}{2}(12)(11)= 66 \ in^{2}\)
But there are four triangle faces, so \(A_{faces} =4(66)=264 \ in^{2}\).
Therefore, the area of each triangular face is 66 square inches.
So, the total surface area would be the sum
\(S=144+264=408 \ in^{2}\)
Therefore, Gabriel needs 408 square inches to paint the whole model.

Which equation below represents the following: "The boardwalk has two bike rental shops. Ray’s Rentals charges a rate of $14.00 plus $9.00 an hour to rent a bike. Bentley’s Bikes charges a rate of $18 plus $7 an hour to rent a bike. For what number of hours would the companies charge the same?" You are not solving this problem, just select the proper equation. (h = number of hours)
14h + 9 = 18 + 7h
14 + 9h = 18 + 7h
14 + 9h = 18h + 7
so which one is it?

Answer the questions below.
(a)
The perimeter of the rectangular garden is 330 m.
If the width of the garden is 77 m, what is its length?
Length of the garden: [] m.
(b)
The area of a rectangular window is 6734 cm².
If the length of the window id 91 cm, what is its width?
Width of the window [] cm.
Answers
(A):88
(B):74
Explanation:
For (A), first multiply 77 by 2 then subtract from 330
77x2=154
330-154=176
For (A), second divide 176 by 2
176/2=88
Length=88
For (B), divide 6734 by 91
6734/91=74
Hope this helps!
Answer:
(a) 88 m
(b) 74 cm
Step-by-step explanation:
You want the length of a garden with a perimeter of 330 m and a width of 77 m, and you want the width of a window with an area of 6734 cm² and a length of 91 cm.
(a) PerimeterThe perimeter of a rectangle is given by the formula ...
P = 2(L +W)
Filling in the given values, we can find the unknown.
330 = 2(L +77)
165 = L +77 . . . . . . . divide by 2
165 -77 = 88 = L
The length of the garden is 88 meters.
(b) AreaThe area of a rectangle is given by the formula ...
A = LW
Filling in the given values, we can find the unknown.
6734 = 91W
6734/91 = 74 = W
The width of the window is 74 cm.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

I simply multiplied the equation on both sides by the denominators of each fraction to get whole numbers. You can also do this by multiplying by 20, since the product of the denominators is 20 and will guarantee to create a numerator that creates a fraction that is also a whole number.

The 500 increase from March to April: 4387+500= 4887
Formula of change: amount of change/ original amount *100.
500/4837*100= 11,397%
Answer: The percentage change is 16%.
Step-by-step explanation:
February:
4,100 water bottles.
March:
(4,100 + 7/100 x 4,100) water bottles
(4,100 + 287) water bottles.
4,387 water bottles.
April:
(500 + 4,387) water bottles.
4,887 water bottles.

The vertices of a triangle are A(2,5), B(1,2), and C(3,1). Find the coordinates of the image after a rotation 90° clockwise about the origin.
Answers
Answer:
The images are;
A’ (5,2) B’ (2,1) and C’ (1,3)
Step-by-step explanation:
Firstly, we want to reflect across the x-axis
When we reflect a point (x,y) over x-axis, we get (x,-y)
So;
A ( 2,5) becomes (2,-5)
B (1,2) becomes (1,-2)
C ( 3,1) becomes (3,-1)
Then we proceed to rotate 90 degrees counterclockwise about the origin
Here we have;
(x,y) becomes (-y,x)
(2,-5) becomes (5,2)
(1,-2) becomes (2,1)
(3,-1) becomes (1,3)
