So there are 36 carpenters and 29 showed up on a certain day. Were looking for the precent.
First, lets set up a proportion.
29/36 = ?/100
We need to cross multiply so that we can find out what the precent is.
29x100
divided by 36
Around 81 percent.
Answer:
x-intercept: (5,0)
y-intercept:(0,10)
Step-by-step explanation:
Answer:
2 1/4
Step-by-step explanation:
Number 1 is incorrect because 1/4 x 9 is 2 1/4 not 1 1/4.
To multiply fractions, multiply directly across. So multiply 1/4 x 9/1 to get 9/4 which converted into a mixed number is 2 1/4.
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
