10y=x because if you multiply your y by 10, you would get the x
Answer:
For 3 quarters, the probability that all 3 quarters will land heads up is ;
P = 1/2 × 1/2 × 1/2 = 1/8
P = 1/8
Step-by-step explanation:
The probability that one quarter will land heads up is 1/2.
For 3 quarters, the probability that all 3 quarters will land heads up is ;
P = 1/2 × 1/2 × 1/2 = 1/8
P = 1/8
Answer: A. They are both incorrect
Step-by-step explanation:
x=3√2
y=6
z=3√2
-----------------------
45-45-90=1:1:√2
------------------------
solve for x
x is the side accordingly to 90 in the smaller triangle, so it should be the [45] side times √2
3×√2=3√2
-----------------------
solve for y
y is the side accordingly to 90, so it should be the [45] side times √2
3√2×√2=6
----------------------
solve for z
z is the side accordingly to 45 in the bigger triangle, x is also accordingly to 45 in the bigger triangle
z=x
z=3√2
Answer:
15
Step-by-step explanation:
1/10 of 50 is 5, so remove that.
2/3 of 45 is 30, so remove that too.
therefore, 15 kids are in school
hope this helps!! <3
Split 8 into 4and 4. when u put parenthesis()around numbers, u add , multiply, subtract or divide whst is in the parenthis first. In this case we are multiplying so we would do (4x4)x7=56
