11/3 - 2/3 = 9/3 = 3 so he spent 3 more hours reading on saturday than on friday
Hope this helps!
If it’s is a right triangle then
A^2 + B^2 = C^2
3^2 + (square root of 8)^2 = 17^2
I don’t have a calculator but type that in and if it doesn’t equal 17^2 than the answer is no it doesn’t make a right triangle
Answer:
(2, 6)
Step-by-step explanation:
Because 8(2)-2(6)=16-12=4.
When atleast one dice shows a 6 the possible outcomes will be:
(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)
(1,6), (2,6), (3,6), (4,6), (5,6)
Thus there are 11 total possible outcomes.
Among these outcomes, the sum of numbers greater than or equal to 9 can be obtained from:
(6,3), (6,4), (6,5), (6,6), (3,6), (4,6), (5,6)
This means there are 7 outcomes with sum greater than or equal to 9.
Thus, Probability of rolling a number greater than or equal to 9 with atleast one dice showing a 6 = 9/11
So, option A gives the correct answer
Use the quadratic formula to solve. the answer is the third one down
x= -sqrt10 - 4 and sqrt10 - 4
or in their notation above x= -4+/-10--sqrt
