The area of the circle 171.94 cm (rounded to the nearest whole would be 172 cm)
A= πr²
A= 3.14 (7.4)²
A= 3.14 (54.76)
A= 171.94 cm
The answer would be D (20,493) because you would multiply 75.9 times 270.
B=brianne present age
c=camila present age
b=3c (brianne is three times as old as camila)
b+4=2(c+4) (four years from now she will be two times as old as Camila)
<span>b + 4 = 2c + 8
b = 2c + 8 - 4
b = 2c + 4
Replace b with 3c
3c = 2c + 4
3c - 2c = 4
c = 4
Camila is four years old.
b+4=2c+8
b=2(4)+4
b=8+4
b=12
Brianne is 12 years old. </span>
Answer:
Step-by-step explanation:
y=4x
A)
150 were surveyed, possible outcomes, and 132 said they prefer dogs, favorable outcomes, 132/150 or 22/25 or 0.88, now 0.88 * 100 is just 88, namely 88% is the probability.
b)
since we know is 88%, what is 88% of 100? (88/100) * 100, 0.88 * 100, or just 88 students.
c)
18/150 or 3/25 or 0.12 namely 12%,
what's 12% of 300? (12/100) * 300, or 0.12 * 300, so just 36 students.
