Answer:
Answer B
Step-by-step explanation:
You need to first find the surface area of the triangular prism.
In order to do that, we need to first know the length of the base of the triangles on both side. So, I used the pythagorean theorem (a²+b²=c²) after making the triangle a right triangle by cutting it in HALF.
a²+b²=c²
a²+2.6²=3²
a²+6.76=9
Subtract 6.76 on both sides
a²=2.24
a=√2.24
a=1.49666295471
Now, we know that the base of HALF of the triangles on both sides of the prism is 1.496......
We need to MULTIPLY this by 2 to get the full length. So, the length of the bases of both triangles is 2.99332590942
The height of the triangles is 2.6
We are going to first find the area of one triangle and multiply it by 2, to get the area of both triangles.
Area of a triangle = base x height ÷ 2
2.6 x 2.99332590942= 7.78264736449
7.78264736449 ÷ 2 = 3.89132368224
3.89132368224 x 2 (because we have 2 triangles) =7.78264736449 cm squared
Now, we know the area of both triangles, but we now need to add the add the surface area of the rectangles in the net.
Area of a rectangle = length x width
We know that all of the three rectangles are equal in size, and that the length of each one of them is 15 cm. However, the width/height of each one is unknown. We will find out the height of each one by looking at the length of the base of the triangle attached to the first one. We know that because of the base of the triangles = 2.99332590942, the width of the attached rectangles are 2.99332590942. We found this using the Pythagorean theroem (look above).
15 x 2.99332590942= 44.8998886413
44.8998886413 x 3 (because we have 3 of the same rectangles)= 134.699665924 cm squared
Now, we must ADD the surface area of the rectangles AND the triangles.
7.78264736449 (triangles) + 134.699665924 (the three rectangles)= 142.482313288 cm squared.
The CLOSEST OPTION to the answer we got is ANSWER B because it is 142.8 cm squared, which is the closest to the answer we got which was 142.482313288 cm squared.
I really hope this helps :)

A rectangle is shown. A line is drawn from a corner to the opposite corner to form 2 triangles. The area of a rectangle in 24 square units. A diagonal drawn from one corner to another divides the rectangle into two right triangles. What is the area of the shaded triangle? 2 times 24 square units 1 times 24 square units One-half times 24 square units One-fourth times 24 square units.
Answer:
Area of shaded triangle = one - half times 24 square units.
Step-by-step explanation:
The line that is drawn from one corner to the opposite corner is called the diagonal of the rectangle.
The diagonal splits the rectangle into 2 right angled triangle of same measurements.
Therefore,
[tex]Area \ of\ rectangle\ =\ Area \ of \ triangle + Area \ of \ triangle \\\\Area \ of\ rectangle\ =\ 2 \times\ Area \ of \ triangle\\\\24 = 2 \times Area \ of \ triangle\\\\Area \ of \ triangle = \frac{1}{2} \times 24[/tex]

Answer: pi(160) or 160 pi
Step-by-step explanation:
First find the area of the whole circle.
A=pi(r^2)
A=pi((18+4)^2)
A=pi(484)
Next find the area of the none shaded circle.
A=pi(r^2)
A=pi(18^2)=pi(324)
Then subtract to get pi(160)

Simplify the following radical expression.
(7 + √13)(7 − √13)
Answer:
36
Step-by-step explanation:
(7+[tex]\sqrt{13[/tex] )(7-[tex]\sqrt{13[/tex] )
this is in the form of a^2-b^2 formula
a^2-d^2=(a-b)(a+b).so write,
(7)^2-([tex]\sqrt{13[/tex] )^2
=49-13
=36
[tex] \huge \mathrm{ \underline{Answer : }}[/tex]
The given expression can be written as :
[tex]( 7 + \sqrt{13} )(7 - \sqrt{13} )[/tex][tex](7) {}^{2} - ( \sqrt{13} ) {}^{2} [/tex][ by applying identity, (a+b) × (a-b) = a²-b² ]
[tex]49 - 13[/tex][tex]36[/tex]Therefore, we will get 36 as our simplified answer.

On Tuesday, the temperature in Fairfield, Montana fell from 51 degrees Fahrenheit at noon to -9 degrees Fahrenheit at midnight. What was the average temperature change per hour.
Answer:
5 degrees
Step-by-step explanation:
First let's find out what the total change in degrees was. This should be 51 degrees to reach 0, plus 9 more to reach -9
51 + 9 = 60
Now we need to find how many hours we are dealing with. Just counting (12 pm to 1 pm is 1 hour, 1 pm to 2 pm is another hour, and so on...) we find that we have 12 hours.
So, now we just divide the degrees by the hours and get
60/12 = 5
You can also double check this by doing
51-5-5-5-5-5-5-5-5-5-5-5-5 = -9
Answer:
5 degrees

The band club needs $1328 for decorations for this year’s concert. So far, they have $43. Find the minimum amount each of the 30 members can raise to meet their goal.
2 step Inequalities
Answer:
$42.83
Step-by-step explanation:
1: Subtract the amount they have by the amount they need.
1328-43= $1,285.
2: Divide amount they need ($1,285) by the total staff members (30). Hence the equation is 1285 ÷ 30
3: Whatever answer you get from that equation is the answer
1285 ÷ 30 = $42.83
When you divide, you are setting the amount each staff member needs to donate by seeing how much money 30 people can give (equally) that adds up to 1285.
Hope this helps :)

The farmer needs to buy fertilizer to spread on his garden. The garden is a 20 x 15 rectangle. A bag of fertilizer covers 30 ft.² of garden. How many bags of fertilizer will be needed?
Answer:
[tex]10[/tex]
Step-by-step explanation:
The area of a rectangle is given by [tex]A=lw[/tex], where [tex]l[/tex] is the length of the rectangle and [tex]w[/tex] is the width of the rectangle. Therefore, the area of a 20 x 15 rectangle is equal to [tex]20\cdot 15=300\:\mathrm{ft^2}[/tex].
Since one bag of fertilizer covers 30 square feet, the farmer needs [tex]\left \lceil \frac{300}{30}\right \rceil=\boxed{10}[/tex] bags of fertilizer.
Answer:
10 bags of fertilizer.
Step-by-step explanation:
300 area
300 / 30 = 10 bags
Solve for x in the diagram below
Answer:
x = 12
Step-by-step explanation:
The 2 angles add up to 90 degrees, so 3x + x + 42 = 90
3x + x + 42 = 90
Subtract 42 from both sides:
3x + x = 48
3x + x = 4x, so
4x = 48
Divide both sides by 4:
x = 12
