The answer is 11 because the longer side would be 16
Answer:
B.70
Step-by-step explanation:
For one or two angles are complementary angle(s), they have to equal 90°.
So, we need to find the larger angle, but what about the other?
Let x be the other angle and y be the angle we are looking for
x + y = 90
Lets look for x first, since one angle is ten less than four times the angle we are looking for or visa versa, we must:
y = 4x - 10
For an exchange, lets take out the y variable for another x variable:
So now we should have x + 4x - 10 = 90
Combine like terms and do cross equation :
x + 4x -10 = 90
5x - 10 = 90
Add 10 to both sides:
5x = 100
100/5 = 20
So <u><em>x=20</em></u>
<u><em></em></u>
Now for y which is what we are looking for,
y = 4x - 10
Since x is 20, plug it in
y = 80 - 10
y=70 is our larger angle
That would be B, C and E.
A and D could be a rhombus.
Answer: There are 20 ways and 1680 ways respectively.
Step-by-step explanation:
Since we have given that
Total number of blocks = 6
Number of red blocks = 3
Number of green blocks = 3
So, Number of patterns she can make by placing them all in a line is given by
If there are 3 white blocks
so, total number of white blocks becomes 9
So, Number of total pattern she can make by placing all nine blocks in a line is given by
Hence, there are 20 ways and 1680 ways respectively.
I'm not confident with the Mean but the rest should be correct.
Mean - 709.6 ( All numbers added up then, divided by the numbers there are)
Median - 65 ( Number in the middle)
Mode - 65 ( Most repeated number)
Range - 8 ( Greatest number - Smallest number)
