Answer:
30/100 or 3/10
Step-by-step explanation:
A percent is out of 100. So since 30 is an even number then it would be 30/100 or 3/10.
Insert x = 7
so 3/(7+2) - sqr (7-3)
=3 / (9) - sqr (4)
= 1/3 - 2
=1/3 - 6/3
= -5/3
Answer:
Explanation:
Assuming that
is a diameter, and that the angle of an arc subtending the central angle is congruent,
.
And according to the arc addition postulate,
.
Using the substitution property:
.
Given that
.
Using the substitution property and that the measures apply to the arc addition postulate,
.
.
.
Since
and
are subtending the center of the circle, they form vertical angles and are therefore congruent.
![\overset{\Large\frown}{GF} \: \cong \: \overset{\Large\frown}{CD}](https://tex.z-dn.net/?f=%20%5Coverset%7B%5CLarge%5Cfrown%7D%7BGF%7D%20%5C%3A%20%5Ccong%20%5C%3A%20%5Coverset%7B%5CLarge%5Cfrown%7D%7BCD%7D%20)
According to the definition of a vertical angle,
.
Using the arc addition postulate again,
![\overset{\Large\frown}{CD} + \overset{\Large\frown}{DE} + \overset{\Large\frown}{EF} \: = \:\overset{\huge\frown}{CDF}/\overset{\huge\frown}{CEF}](https://tex.z-dn.net/?f=%20%5Coverset%7B%5CLarge%5Cfrown%7D%7BCD%7D%20%2B%20%5Coverset%7B%5CLarge%5Cfrown%7D%7BDE%7D%20%2B%20%5Coverset%7B%5CLarge%5Cfrown%7D%7BEF%7D%20%5C%3A%20%3D%20%5C%3A%5Coverset%7B%5Chuge%5Cfrown%7D%7BCDF%7D%2F%5Coverset%7B%5Chuge%5Cfrown%7D%7BCEF%7D%20)
Using substitution, as well as how we are given that the central angle subtended by
= 83°, we can find that:
![40° + 83° + \overset{\Large\frown}{EF} \: = \:\overset{\huge\frown}{CDF}/\overset{\huge\frown}{CEF}](https://tex.z-dn.net/?f=%2040%C2%B0%20%2B%2083%C2%B0%20%2B%20%5Coverset%7B%5CLarge%5Cfrown%7D%7BEF%7D%20%5C%3A%20%3D%20%5C%3A%5Coverset%7B%5Chuge%5Cfrown%7D%7BCDF%7D%2F%5Coverset%7B%5Chuge%5Cfrown%7D%7BCEF%7D%20)
Answer:
oh nah 1.98
Step-by-step explanation:
1 gallon equals 16 cups. So, 3 gallons equal
cups.
So, 48 cups cost $13.92, which means that one cup costs
![\dfrac{13.92}{48}=0.29](https://tex.z-dn.net/?f=%5Cdfrac%7B13.92%7D%7B48%7D%3D0.29)
