Use the net to compute the surface area of the three-dimensional figure.
A) 56 units2
B) 62 units2
C) 68 units2
D) 74 units2
Answers
62 units is the answers
Step-by-step explanation:
The correct answer is C) 68 units². The net to compute the surface area of the three-dimensional figure is C) 68 units².
To compute the surface area of a three-dimensional figure, one must consider all the faces that make up the shape. The net of a three-dimensional figure provides a two-dimensional representation of all these faces. By calculating the area of each face and summing them up, we can find the total surface area.
Let's assume the net provided shows a figure composed of rectangles and triangles. We will calculate the area of each face as follows:
1. For rectangles, the area is given by the formula A = length × width.
2. For triangles, the area is given by the formula A = 1/2 × base × height.
Let's denote the lengths of the sides of the rectangles as l and w, and the base and height of the triangles as b and h, respectively.
Now, let's calculate the area of each face:
- Rectangle 1: A1 = l × w
- Rectangle 2: A2 = l × w (assuming it has the same dimensions as Rectangle 1)
- Triangle 1: A3 = 1/2 × b × h
- Triangle 2: A4 = 1/2 × b × h (assuming it has the same dimensions as Triangle 1)
The total surface area (SA) is the sum of the areas of all faces:
SA = A1 + A2 + A3 + A4
SA = (l × w) + (l × w) + (1/2 × b × h) + (1/2× b × h)
SA = 2lw + bh
SA= 2*5*3+19*2
SA=68
After performing these calculations with the given measurements from the net, we would find that the total surface area is 68 units².
Therefore, the correct answer is C) 68 units²."

Andrew has a container with 80 game pieces that are different colors.He knows that the probability of choosing a green piece at random from the container is 0.2 and the probability of choosing a yellow piece at random from the container is 0.45. What is the total number of yellow game pieces in the container?
Answers
Answer:
36 Yellow pieces
Step-by-step explanation:
-Given the total number of pieces is 80 and the probability of choosing a yellow piece at random is 0.45.
-To find the number of yellows pieces in the container, we multiply its probability by the total number of pieces;
[tex]n_y=P(yellow)\times n\\\\=0.45\times 80\\\\=36[/tex]
Hence, the total number of yellow pieces is 36
Final answer:
To find the total number of yellow game pieces in the container, we can use the given probabilities to calculate the number of yellow pieces. By setting up equations based on the information provided, we determine that there are 8 yellow game pieces in the container.
Explanation:
Let's first calculate the total number of game pieces in the container.
Let x be the total number of yellow game pieces. The total number of game pieces is 80.
Given that the probability of choosing a green piece is 0.2 and the probability of choosing a yellow piece is 0.45:
Let the number of green pieces be (80 - x), so 0.2(80 - x) = 4 - 0.2x
Now, we know the number of yellow pieces is x, so 0.45x = 0.45x
Solving the equations, we get x = 8, thus there are 8 yellow game pieces in the container.
If log2 5 = k, determine an expression for log32 5 in terms of k.

Step-by-step explanation:
Let's start by using change of base property:
[tex]log_b(x)=\frac{log_a(x)}{log_a(b)}[/tex]
So, for [tex]log_2(5)[/tex]
[tex]log_2(5)=k=\frac{log(5)}{log(2)}\hspace{10}(1)[/tex]
Now, using change of base for [tex]log_3_2(5)[/tex]
[tex]log_3_2(5)=\frac{log(5)}{log(32)}[/tex]
You can express [tex]32[/tex] as:
[tex]2^5[/tex]
Using reduction of power property:
[tex]log_z(x^y)=ylog_z(x)[/tex]
[tex]log(32)=log(2^5)=5log(2)[/tex]
Therefore:
[tex]log_3_2(5)=\frac{log(5)}{5*log(2)}=\frac{1}{5} \frac{log(5)}{log(2)}\hspace{10}(2)[/tex]
As you can see the only difference between (1) and (2) is the coefficient [tex]\frac{1}{5}[/tex] :
So:
[tex]\frac{log(5)}{log(2)} =k\\[/tex]

The cylinder’s diameter and height are both 39.2 millimeters. What is the surface area of this cylinder?
Answers
Answer:
A = 7,241.2454026112 square mm.
or exact : A = 2,304.96*π sq mm
Step-by-step explanation:
Cylinder formula: A = π* r^2 + 2 *π * r* h + π*r^2
is the surface area.
d = 2r = 39.2 mm
h = 39.2 mm
r = 19.6 mm
A = π* r^2 + 2 *π * r* h + π*r^2
A = 2* π* (19.6)^2 + 2π (19.6)*(39.2)
A = 2,413.748467537 + 4,827.496935
A = 7,241.2454026112 square mm.
or
A = 2*pi* (768.32 + 384.16)
A = 2*1,152.48* pi

The number of inches of rain,y,after x minutes of rainfall during a storm can be modeled by the equation y=0.003x How many inches of rain will have fallen after 2 minutes
Answers
Answer:
Therefore 0.006 inches of rain will have fallen after 2 minutes.
Step-by-step explanation:
Given that,
y = 0.003x
where y is the number of inches of rain after x minutes.
To find the number of inches of rain after 2 minutes, we plug x = 2 minutes in above model equation.
∴ y= 0.003×2
=0.006
Therefore 0.006 inches of rain will have fallen after 2 minutes.
After 2 minutes, 0.006 inches of rain will have fallen based on the equation y = 0.003x. This calculation involves substituting x with 2 and multiplying by 0.003.
To determine how many inches of rain will fall after 2 minutes using the given equation y=0.003x, we substitute x with 2.
Start with the equation: y = 0.003xSubstitute x with 2: y = 0.003 × 2Calculate the value: y = 0.006So, the number of inches of rain that will have fallen after 2 minutes is 0.006 inches.

An apple costs $2.25. A mango costs $1.25.
Step-by-step explanation:
Let a = price of 1 apple.
Let m = price of 1 mango.
Cameron:
4 apples + 7 mangoes ----> total $17.75
4a + 7m = 17.75
Gavin:
2 apples + 5 mangoes ----> total $10.75
2a + 5m = 10.75
We have a system of 2 equations in 2 unknowns.
4a + 7m = 17.75
2a + 5m = 10.75
We can use the elimination method to eliminate the variable a. Rewrite the first equation. Multiply both sides of the second equation by -2 and write below it. Then add the equations.
4a + 7m = 17.75
(+) -4a - 10m = -21.5
---------------------------------
-3m = -3.75
Divide both sides by -3.
m = 1.25
A mango costs $1.25.
Now we use the first equation and substitute 1.25 for m and solve for a.
4a + 7m = 17.75
4a + 7(1.25) = 17.75
4a + 8.75 = 17.75
4a = 9
a = 2.25
An apple costs $2.25.
Answer: An apple costs $2.25. A mango costs $1.25.
Answer:
2.25 ; 1.25
Step-by-step explanation:
4A + 7M = 17.75
2A + 5M = 10.75
2A = 10.75 - 5M
4A = 21.5 - 10M
21.5 - 10M + 7M = 17.75
3.75 = 3M
M = 1.25
4A = 21.5 - 10(1.25)
4A = 9
A = 2.25

Answers
Answer:
Headband: 15.98 in.
Wristband: 8.63 in.
Step-by-step explanation:
In this problem, we call:
h = the amount of fabric used for each headband
w = the amount of fabric used for each wristband
We are told that:
Sean uses 671.16 in at on headbands for 39 players and three coaches, so the total number of headbands made is 42
Therefore, we can write
[tex]671.16 = 42 h[/tex]
And solving for h, we find
[tex]h=\frac{671.16}{42}=15.98 in.[/tex]
Then we also know that Sean uses 336.57 in the fabric on wristbands just for the players, so he produced 39 wristbands; so we can write:
[tex]336.57 = 39w[/tex]
And solving for w,
[tex]w=\frac{336.57}{39}=8.63 in.[/tex]
