Answer:
16* C
Step-by-step explanation:
This is simply 20 - 4
---> 20 - 4 = 16
=> Celcius (C)
Thus, 16° C
Answer:
Step-by-step explanation:
1/2(13-5)+(4+8)^2
A. 148
B. 144
C. 20
D. 16
We must follow "PEMDAS" order of operations rules. Anything inside parentheses must be done first, followed by exponentiation, multiplication and division, and finally additionl and subtraction.
1/2(13-5)+(4+8)^2 has three sets of parentheses enclosing mathematical expressions: (1/2), (13 - 5) and (4 + 8). These evaluate to:
1/2, 8, 12
and so we now have (1/2)(8) + (12)^2
Exponentiation is next. We get: (1/2)(8) + 144
Next is multiplication: 4 + 144
Last is addition: 148
Answer A is correct: 148
8 x 9+4^2-(63/7)
is evaluated in the same way:
8 x 9+4^2-(9), followed by exponentiation:
8*9 + 16 - 9, followed by multiplication:
72 + 16 - 9 = 79 (Answer C)
Ratio tables are like proportional relationships (if you know what that is), and you have to do this:
6:9 is related to a:45 we don't know a, but since the prior ratio is related to this one, you simply take 9 times what is 45. The answer is 5, so then you multiply 6 times 5 to get 30. Then keep building off of that. The next problem will be 48, then 72.
The bottom ratios start with 10:15. 15 times 3 is 45 so 10 times 3 is 30. The next one is 100, then 70. Hope this helps, sorry that it's confusing!
