Help me please :) its very hard
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 :)
Answer:

A linear relationship is given in the table.
x −2 −1 0 1 2
y −18 −12 −6 0 6
What is the slope of the relationship?
−6
negative one sixth
one sixth
6
Is the linear relationship also proportional? Explain.
No, the constant of proportionality is 2.
Yes, the constant of proportionality is 2.
No, there is no constant of proportionality.
Yes, there is no constant of proportionality.
Step-by-step explanation:
To find the slope
m = ∆y/∆x
m = (6 -0)/(2-1)
m = 6/1= 6
hence the slope is 6
now the other question
y = m(x -x1) +y1
y = 6(x - 1) +0
y = 6x -6
none of the options are right.
Answer:
Step-by-step explanation:
To find the slope of the linear relationship, we need to use the formula:
slope = (change in y) / (change in x)
We can choose any two points from the table to find the change in y and change in x. Let's choose the points (A1 ,B1)=(-1, -12) and (A2,B2)= (1, 0):
change in y =(B2-B1)= 0 - (-12) = 12
change in x =(A2-A1)= 1 - (-1) = 2
slope = change in y / change in x = 12 / 2 = 6
Therefore, the slope of the relationship is 6.
To determine if the linear relationship is also proportional, we need to check if the ratio of y to x is constant for all pairs of x and y in the table. calculate the ratios for each pair of x and y:
-2: -18/-2 = 9
-1: -12/-1 = 12
0: -6/0 (undefined)
1: 0/1 = 0
2: 6/2 = 3
We can see that the ratios are not constant, so the linear relationship is not proportion

Write your answer to the tenths place.
Find the 24th term.
-9, 0, 9, 18, 27, ...
24th term = [? ]
Answer:
198
Step-by-step explanation:
Answer: 198
Step-by-step explanation:
Firstly, you must find the nth term.
the sequence is: -9, 0, 9, 18, 27, ...
find the difference between each term. in this sequence, the difference is 9, so it is 9n
then you must find the difference between the sequence 9n and this sequence. 9n is:
9, 18, 27, 36, 45, ...
now find the difference between 9n and our sequence.
adjustment = -18
so the nth term is 9n - 18
now you need to substitute 24, as that is the term you would like to find out, in place of n.
so, our n term looks like this: 9(24)-18
9 x 24 = 216
216 - 18 = 198
hence, the answer is 198.
hope this helps.

Suppose a cheetah could travel 1.5 hours a top speed covering 111.9 miles how far could the cheetah travel in 1 hour
The number of miles that the cheetah will travel in 1 hour based on the ratio will be 74.6 miles.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
A cheetah could travel for 1.5 hours at a top speed covering 111.9 miles.
The ratio of the number of miles to time = 111.9/1.5
With the same ratio, the number of miles x in 1 hour will be as,
x/1 = 111.9/1.5
x = 74.6 miles.
Hence "The number of miles that the cheetah will travel in 1 hour based on the ratio will be 74.6 miles:".

Two angles are vertical angles. The measure of one angle is (3x) degrees. The measure of the other angle is 42 degrees. What is the value of x?
Answer:
x =14
Step-by-step explanation:
Vertical angles are equal.
This means that 3x = 42
Divide each side by 3
3x/3 = 42/3
x =14
Answer: x=46.
Step-by-step explanation:
Vertical angles are opposite of one another. A whole line is 180 degrees. You have to subtract 42 from 180 which gives you 138. Then you divide by 3. Then you get 46.

a stack of 500 pieces of paper is 1.875 inches tall derion guesses that each piece of paper is 0.015 inches thick. explain how you know that derions answer is not correct.
compute the thickness of each piece of paper. show your reasoning
Answer:
Derions answer is not correct becuase 500 x 0.015=7.5 inches. If he got this as an answer that would meen that the stack of paper is 7.5 inches tall, which is not correct.
If we divide 1.875 by 500 we get 0.00375 which is the thickness of each sheet of paper.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

whats the surface area?
Answer:
1108 in²
Step-by-step explanation:
You want the total surface area of the pentagonal prism shown.
Base areaThe area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...
A = LW +1/2bh
A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches
Lateral areaThe lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.
LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches
Total areaThe total surface area of the figure is the sum of the two base areas and the lateral area:
SA = 2(114 in²) +880 in² = 1108 in²
The surface area of the composite figure is 1108 in².

An appliance store sells an oven for 25% off the original price. The sale price is $251.85, not including tax. What is the price of the oven, not including tax, before the discount is applied. Show your work please I will be marking brainliest.
Answer:
$352.31
Step-by-step explanation:
Appliance store sold the oven for 25% off original price.
Sale price =$281.8
Price of the oven before the discount was applied is
= 25% /100% x $281.85
= 0.25 x $281.85
= $70.46
The appliance was sold at $70.46 less than the original price
Original price
= $70.46 + $281.85
= $352.31
