Answer:
A) Bobby's overall grade is 70.4%
Step-by-step explanation:
To solve this problem we must calculate the percentages each grade represents from the overall grade. Therefore:
assignment = 85*30% = 85*30/100 = 25.5%
tests = 72*20% = 72*20/100 = 14.4%
exam = 61*50% = 61*50/100 = 30.5%
total = assignment + tests + exam
total = 25.5 + 14.4 + 30.5 = 70.4
Bobby's overall grade is 70.4%. Therefore the correct answer is A).
Answer:
A Between 1.43 in. and 1.47 in.
Step-by-step explanation:
If the circumference is between 9 and 9.25 inches, and we know that circumference equals 2 * pi * radius, we can solve to find that the radius equals the circumference divided by 2pi. So we get between 1.43 in and 1.47in
So we see our equation, clear:
y=8^x
Let's just plug in values of x from 1-4.
y= 8^1=8; So, it would be (1,8).
y= 8^2=64; So, it would be (2, 64).
y = 8^3= 512; So, it would be (3,512).
y= 8^4 = 4096; So, it would be (4, 4096).
