Answer:
$198
Step-by-step explanation:
To find how much the tax was, we multiply 10% by 220. We do this in decimal form, so we write it as 0.1*220. 0.1*220 is 22. Although, we don't stop there. Now that we know how much tax is, we must subtract the tax from the price with tax to find the OG price. 220-22 is 198. That means our answer is $198. Hope this helps!
Answer:
0.375 is answer
Step-by-step explanation:
Given that the math teacher gave her students two tests. On the first test, 80% of the class passed the test. But only 30% of the class passed both tests.
Let A - the students pass I test
B = students pass second test
Then P(A) = 80%=0.8 and P(AB) = 30% =0.30
Required probability =probability that a student passes the second test, given that they passed the first one
= P(B/A) = P(AB)/P(A)
= 0.30/0.80
=3/8
=0.375
Right answer is 0.375
22. not sure but I think that it is the first one y=3/(x-2)+1
23. 3rd y=2
24. third one y=4/(x-3)
2n picture: second one y=(15/(x+11))-7
3rd graph picture: fourth x>2.5
The answer is D. 12
To find this you would add (5x+16) and (9x-4) and set them equal to 180, because angles on a straight line add up to 180:
5x+16+9x-4 = 180
Then you would solve that for x, and would get x=12
Hope this helps!
