Answer:
Explanation:
The figure labeled A cannot be because the cross and the line are not oriented in the same relative position as in X.
The figure labeled B cannot be because the line and the the image with the three lines are not oriented in the same relative position as in X.
You cannot tell about the figures labeled C because you do not see the images of the cross and the line.
The figure labeled E cannot be because the image with the three lines is not oriented in the same relative positiion with respect to the other two as in X.
You cannot tell about the figure labeled F because the image of the cross and with the three lines are not shown.
The figure labeled G is correct: you can just rotate the cube labeled X 90 degrees counterclockwise about a vertical axis that passes through the center of the cube and get the cube labeled G.
The answer is
round cake - 82.42 in²
rectangular cake - 114 in²
Round cake:
d = 7 in
r = d/2 = 7 in / 2 = 3.5 in
h = 2 in
The surface are of a cylinder is:
A = 2πr² + 2πrh
The surface are of the round cake (which is actually a cylindrical cake) excluding the bottom is:
A = 2πr² + 2πrh - πr²
A = πr² + 2πrh
A = 3.14 * 3.5² + 2 * 3.14 * 3.5 * 2
= 38.46 + 43.96
= 82.42 in²
Rectangular cake:
w = 6 in
l = 9 in
h = 2 in
The surface are of a rectangle is:
A = 2wl + 2wh + 2lh
The surface are of the rectangular cake excluding the bottom is:
A = 2wl + 2wh + 2lh - wl
A = wl + 2wh + 2lh
A = 6 * 9 + 2 * 6 * 2 + 2 * 9 * 2
= 54 + 24 + 36
= 114 in²

Answer:
The tree diagram is shown below.
Step-by-step explanation:
The color of the four skittles Junior had in his bag are:
S = {red (R), blue (B), green (G) and yellow (Y)}
It is provided that Junior takes a skittle out and eats it and then takes another skittle from the bag.
So, Junior has four options for the first draw, i.e. {R, B, G and Y}.
Then three options for the second draw. But the second draw is dependent on the first draw.
- If Junior ate the red skittle first, then the second skittle could be any of the three, (B, G and Y).
- If Junior ate the blue skittle first, then the second skittle could be any of the three, (R, G and Y).
- If Junior ate the green skittle first, then the second skittle could be any of the three, (R, B and Y).
- If Junior ate the yellow skittle first, then the second skittle could be any of the three, (R, B and G).
Consider the tree diagram below to better understand the information above.
I would tell you but the answer wont show sorry. :)
