Answer:
B. 66
Step-by-step explanation:
45% of 400
.45 x 400 = 180 (number of girls)
400 - 180 = 220 (number of boys)
30% of 220
.30 x 220 = 66
Answer:

Step-by-step explanation:
Answer:
B
Step-by-step explanation:
.4 as we know can also be handled as .40, as the zero helps us determine the difference in value. 50%, though it is a percentage, can be put into decimal form. That would be .5, or again, we could add a zero to help us out, which would make it .50. As of right now, .4 is less than 50%. 3 and 13 are whole numbers, so they do not really need deep observation, except that 3 is less than 13. That would make the order of number from least to greatest .4, 50%, 3, and 13.
f(x)=3x^2 and g(x)=4x^3+1
(f*g)(x) = (3x^2)(4x^3 + 1)
(f*g)(x) = 12x^5 + 3x^2
The term with highest degree is the first term 12x^5, so the degree of the product is 5.
Answer: C. 5
