1 pt; or 1 pint seems most reasonable here.
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)
Let 4units represent 800g, since the ratio of the masses is 7:5:4, with 800g being the lightest.
1 unit = 800/4 = 200g
hence, the mass of the heaviest cake will be 7 units, which is 7 x 200g = 1400g
Answer:
I'm pretty sure you substitute G into the expression.
Step-by-step explanation:
23. Given equation: g-(-7)
G=121
121-(-7)= 128
Hope this helped!
