Answer:
3/7
Step-by-step explanation:
The ratio is the number of red marbles and the number of blue marbles in a fraction, so the ratio would be 3/7
Answer:
x = 1
Step-by-step explanation:
Rearrange equation by making x's on one side and numbers on the other
2x - x = 9 - 8
x = 1
Answer:
A) 1/6 & 1/12 (with borders) 1/3 & 1/6 (without borders)
B) 1/4 & 1/12 (with borders) 1/2 & 1/6 (without borders)
C) 1/4 & 1/4 (with borders) 1/2 & 1/2 (without borders)
Step-by-step explanation:
What we know:
shape is circular
Area=64π yr²
Area=πr²
circumference=2πr
In order to find circumference we need r=radius. We can use the area to find r by solving for r using substitution of the information we know above.
Area=πr²
64π=πr² substitution
64π/π=π/πr² multiplicative inverse
64=r²
√64=√r² properties of radicals
8=r We would get two solutions, a positive and negative one but we will only use the positive solution since radius is positive
Circumference=2πr
C=2π(8)=16π yards
