how are the two coin stacks different from each other?
does either stack of coins resemble a geometric solid? if so which stack and what solid?
how do the heights of the two stacks compare?
how do the volume of the two stacks compare? explain your reasoning.
Answers
Question 1
You probably agree that it's fairly obvious that the stack on the right is slanted, while the stack on the left is straight up and down (more or less).
--------------
Question 2
The stack on the left resembles a cylinder. It might help to wrap the coins in a paper casing to better see this.
--------------
Question 3
The heights of each stack appears to be the same. This is assuming both stacks have the same number and type of coins.
--------------
Question 4
The two stacks have the same volume. This may seem a bit strange, but if both stacks have the same number and type of coins, then each of the individual coins has the same volume. When put together, the overall 3D solids will have the same volume as well. It doesn't matter if we slanted one of the stacks or not.

SO YOU HAVE TO FIND LENGTH OF THE TRIANGLE
Step-by-step explanation:
I just answered 1.
by using the principle of similar triangles (all angles are the same between the 2 triangles, and the ratio of a corresponding pair of sides is the same for all pairs of sides) we get
AB = 2×38 = 76
AC = 2×24 = 48
WX = CB/2 = 66/2 = 33
2.
the upper small triangle and the whole big triangle are similar triangles.
and we see the ratio of the legs is 1/2 (each leg of the small triangle is half of the leg of the large triangle).
therefore,
3x = 24/2 = 12
x = 12/3 = 4
3.
AC = 16
because the height of C splits the baseline precisely in half, it means that this is at least an isoceles triangle (both legs have the same length). therefore the answer.
AC = CB = 16.

Hi!
I can help you with joy! :)
Remember, the y-intercept is the point where the graph touches the y-axis (that's why it's called y-intercept)
Now, where does the graph touch the y-axis?
It touches the y-axis at (0,1)
Thus, the y-intercept is 1.

PLEASE HELP DUE TODAY DO A AND B PARTS PLEASE PLEASE HELP ME FIGURE OUT THE LENGTH 100 POINTS
Answers
Answer:
Length A: 5 ft
Width B: 4 ft
volume = 88 ft³
Step-by-step explanation:
Length A: 8 - 3 = 5 ft
Width B: 8 - 4 = 4 ft
Volume
The easiest way to calculate the volume is to split the trough into two rectangular prisms. (imagine drawing a horizontal line from the internal corner of A and 4ft to the left 8ft side).
Volume of a rectangular prism = width x length x height
Volume of rectangular prism 1: B x 8 x 2 = 4 x 8 x 2 = 64 ft³
Volume of rectangular prism 2: 3 x 4 x 2 = 24 ft³
Total volume = 64 + 24 = 88 ft³
Now volume of first prism
L=8B=2H=3[tex]\\ \tt\hookrightarrow V=LBH[/tex]
[tex]\\ \tt\hookrightarrow V=8(2)(3)[/tex]
[tex]\\ \tt\hookrightarrow V=48ft^3[/tex]
For next prism
L=5B=4H=2[tex]\\ \tt\hookrightarrow V=5(4)(2)=40ft^3[/tex]

Answer:
A relation is a function if for each value of x (input value) there is a unique value of y (output value). For the equation given in the problem:
y= |x| +4
There is a unique value of y for each value of x.
Therefore, the equation is a function and a function is also a relation.
Then, the answer is option A.

The ratio of centimeters on a map to distance in kilometers is 2 to 5.
If two cities are 16 cm apart on the map, what is the actual distance in kilometers between the two cities? You can use a double number line diagram to help you solve.
Answers
Answer: 40 kilometers
Step-by-step explanation: Since the word ratio is cm/km (centimeter/kilometer), and the number ratio is 2/5, you will have to create another set and put the 16 cm next to the 2 cm. So it would be 2/5=16/X. Now you have to find the value of x. First, you have to multiply 5 by 16, which is equal to 80. Now you divide it by 2 and you will get 40 kilometers as your final answer.
