Lucas built a composite solid by joining 12 identical blocks, with dimensions 4 inches by 5 inches by 7 inches, into three rows of four as shown.
12 blocks are in 3 rows of 4. Each block is 4 inches by 5 inches by 7 inches.
What is the total surface area of the composite solid?
521 square inches
1,042 square inches
1,072 square inches
1,992 square inches
Answer
the answer is b. im not sure though
Step-by-step explanation:
1042 square inches is the total surface area of composite solids.
It is clear from the image that the resulting composite solid is a cuboid.
whose sides are as follows
Across the length, there are 3 blocks along the side of 7 inches each.
[tex]Length = 7 \times 3 = 21\ inch[/tex]
Width = 5 inch
Across the height, there are 4 blocks along the side of 4 inches each.
[tex]Height = 4 \times 4 = 16\ inch[/tex]
What is the total surface area of a cuboid?[tex]\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)[/tex]
We know that the total surface area of a cuboid is,
[tex]\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)\Rightarrow 2 (21 \times 5 + 16 \times 21 + 16 \times 5 )\\\Rightarrow 2 (105 + 336+80)\\\Rightarrow 2 \times 521\\\Rightarrow 1024[/tex]
Therefore, the total surface area = 1024 square inches.

The first one is 8/12.
Step-by-step explanation:Add numerator and keep denominator same.
Answer:
5/12 + 3/12
Step-by-step explanation:
[tex]\frac{5}{12} + \frac{3}{12} = \frac{8}{12}[/tex]
This is because when adding fractions with the same denominator, you just add the numerators.
The other answer choices do not equal 8/12...

It takes a painter and his friend 8 hours to paint a room. If the painter was working alone, it would take him 12 hours less than if his friend was working alone. How long does it take the painter to paint the room by himself? Please explain to get brainliest
Answer:
The painter paint the room by himself in 12h.
Step-by-step explanation:
If we consider that the room is the distance that the painter and his friend need to paint, then each person will have a painting speed and if we sum them they will finish the room in 8 hours. If we call the speed of the painter "x" and the his time "tx", while his friend will be "y" and his time will be "ty". We can apply each case to the average speed formula:
Both working together:
speed = distance / time
x + y = room / 8
The friend alone:
y = room / ty
The painter alone:
x = room / tx
Therefore:
(room/tx) + (room/ty) = room/8
1/tx + 1/ty = 1/8
(tx + ty)/tx*ty = 1/8
8*tx + 8*ty = tx*ty
Since tx = ty - 12, we have:
8*ty - 96 + 8*ty = ty² - 12*ty
ty² - 12*ty - 16*ty + 96 = 0
ty² - 28*ty + 96 = 0
ty = 4 or ty = 24
Since tx = ty - 12, ty can only be 24, because if it was 4, then the painter time would be negative and that is impossible. So we have:
ty = 24
tx = 24 - 12 = 12
The painter paint the room by himself in 12h.
The painter to paint the room by himself in 12 hours
How to find work done by painterLet
Work done by painter friend = xWork done by painter = yFriend
x = room / time taken
Painter
y = room / time taken
painter and friend
x + y = room / 8
(room/friend time ) + (room/painter time) = room/8
1/friend time + 1/painter time = 1/8
(friend time + painter time)/friend time × painter time = 1/8
8 × friend time + 8 × painter time =friend time × painter time
Since friend time = painter time - 12, we have:
8 × painter time - 96 + 8 × painter time = painter time² - 12 × painter time
Painter time² - 12 × painter time - 16 × painter time + 96 = 0
painter time² - 28 × painter time + 96 = 0
solve using factorization methodPt = 4 or = 24
Since friend time = painter time - 12,
Painter can is 24, because if it is 4, then the painter time would be negative and that is impossible.
So,
Painter = 24
Friend time = 24 - 12 = 12
Therefore, the painter paint the room by himself in 12 hours

If two fair dice, one red and one white, are rolled, in how many ways can the result be obtained?
The sum of the two dice is less than 5.
O A. 4 ways
OB. 10 ways
OC. 6 ways
OD. 5 ways
Answer:
C. 6 ways
Step-by-step explanation:
When two fair dice are rolled, the sample space of the outcome is given below:
[tex](1,1) (1,2) (1,3) (1,4) (1,5) (1,6)\\(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)\\(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)\\(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)\\(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)\\(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)[/tex]
Where in the pair (x,y), x represents the red die and y represents the white die.
The outcome in which the sum of the two dice is less than 5 are:
[tex](1,1) (1,2) (1,3) \\(2,1) (2,2) \\(3,1)[/tex]
Therefore, this result can be obtained in 6 ways.
The correct option is C.
Considering all the possible outcomes, it is found that the number of times a sum of the two dice less than 5 can be obtained is:
C. 6 ways
What are the possible outcomes when two dices are rolled?(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)
(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)

Solve the system of equation: y = x + 5 ; y = 2x +2 x= ? , y = ?
I need this ASAP
It's simple Please!!!!!!!
Answer:
x = 3
y = 8
Step-by-step explanation:
y = x + 5
y = 2x + 2
They both equal y, so:
x + 5 = 2x + 2
x + 3 = 2x
3 = x
Put the value of x into the equations:
y = 3 + 5 = 8
y = 2(3) + 2 = 8
x = 3
y = 8
A rectangular prism and a square pyramid were joined to form a composite figure. A rectangular prism with a length of 9 inches, width of 9 inches, and height of 5 inches. A square pyramid with triangular sides with a base of 9 inches and height 4 inches. [Not drawn to Scale] What is the surface area of the figure? 261 in.2 333 in.2 405 in.2 477 in.2
Answer:
The answer is D 477 in.2
Step-by-step explanation:
The surface area of the composite figure is 333 sq. in.
The correct answer is an option (2) 333 in²
What is a pyramid?"It is a three-dimensional geometric shape with a polygon as its base and the lateral surfaces as triangles which meet at a common point."
What is rectangular prism?"It is a three-dimensional geometric structure which has six faces that are rectangles."
What is a composite figure?"A figure that consists of two or more geometric shapes."
Area of rectangle:A = length × width
Area of the triangle:A = 1/2 × base × height
For given example,
A rectangular prism and a square pyramid were joined to form a composite figure.
The composite figure would have nine faces with four triangular faces and five rectangular faces.
Surface area of the composite figure would be the sum of surface area of all nine faces.
The dimensions of the rectangular base the composite figure are length of 9 inches, width of 9 inches.
Using the formula for an area of the rectangle,
⇒ A1 = 9 × 9
⇒ A1 = 81 square inches
The surface area of the larger vertical rectangular faces is same.
So, A2 = 2 × (area of the larger vertical rectangular faces)
The dimensions of the larger vertical rectangular faces 9 inches × 5 inches.
⇒ A2 = 2 × (9 × 5)
⇒ A2 = 2 × 45
⇒ A2 = 90 square inches
Similarly, the surface area of the smaller vertical rectangular faces is same.
So, A3 = 2 × (area of the smaller vertical rectangular faces)
The dimensions of the smaller vertical rectangular faces 9 inches × 5 inches
⇒ A3 = 2 × (9 × 5)
⇒ A3 = 2 × 45
⇒ A3 = 90 square inches
The four triangular faces are identical.
Let A4 be the total surface area of four triangular faces.
⇒ A4 = 4 × (area of triangular face)
⇒ A4 = 4 × (1/2 × base × height)
⇒ A4 = 4 × (1/2 × 9 × 4)
⇒ A4 = 4 × 18
⇒ A4 = 72 square inches
So, the surface area of the composite figure is,
⇒ A = A1 + A2 + A3 + A4
⇒ A = 81 + 90 + 90 + 72
⇒ A = 333 sq. in.
Therefore, the surface area of the composite figure is 333 sq. in.
The correct answer is an option (2) 333 in²

SOLVE EACH Equation by completing the square
1) p2 + 8p - 33 - 0
Answer:
p = - 11, p = 3
Step-by-step explanation:
Given
p² + 8p - 33 = 0 ( add 33 to both sides )
p² + 8p = 33
To complete the square
add ( half the coefficient of the p- term )² to both sides
p² + 2(4)p + 16 = 33 + 16
(p + 4)² = 49 ( take the square root of both sides )
p + 4 = ± [tex]\sqrt{49}[/tex] = ± 7 ( subtract 4 from both sides )
p = - 4 ± 7
Thus
p = - 4 - 7 = - 11
p = - 4 + 7 = 3

A rental car agency charges $12 per day plus 14 cents per mile to rent a certain car. Another agency charges $15
per day plus 9 cents per mile to rent the same car. How many miles per day will have to be driven for the cost of a
car from the first agency to equal the cost of a car from the second agency?
Answer:
The cost of renting will be the same for 200 miles.
Step-by-step explanation:
Let n the number of miles and C be the cost. We can represent the cost equations for each companies:
A: C = 12 + 0.09n
B: C = 8 + 0.11n
They want to know when the cost will be the same, so we can set the above 2 equations equal to each other and solve for n:
12 + 0.09n = 8 + 0.11n
0.02n = 4
n = 200
