Step-by-step explanation:
in probability,or means addition.
14/28+19/28
1/2+19/28
you then find the LCM of the denominator.
14+19/28
33/28
you then divide 33 by 28.
If you subtract the $9.60 from the $53.70 you would be taking out the tip which would be $44.10. Then if you divide the $44.10 by 2, because they both payed equally, you would get $22.05 per person, not including the tip.
Answer:
33

Step-by-step explanation:
A 45-45-90 traingle is a special traingle. Let's say one of the leg of the triangle is x. The other one is also x because of the isosocles triangle theorem. Therefore, using the pytagorean theorem, you find that x^2+x^2=c^2. 2(x)^2=c^2. You then square root both sides and get c= x√2.
Therefore, the two legs are x and the hypotenuse is x√2. x√2=128 because the question says that the hypotenuse is 128. Solve for x by dividing both sides by √2. X=128/√2. You rationalize it by multiplying the numberator and denominator of the fraction by √2. √2*√2= 2.
X=(128√2)/2= 64√2 cm.
Since X is the leg, the answer would be 64√2
