Answer:
Step-by-step explanation:
To find the 
we must use the cosine theorem.
The cosine theorem says that:
In this case:
So
To make this easier, you want to do 5 1/2 into a decimal. 5.5, next divide to find her pace per minute. 12/ 5.5 =2.1818
Multiply that by 60, and your answer is 130
Answer:
according to my calculation Lucita's estimate is too low.
Step-by-step explanation:
because if we divide 3.302 by -1.27 we get -2.6 but lucita wrote 0.026
so it means that she wrote is so low it has to be bigger
hope i helped
can i have brainliest plss
oh guys
Answer:
Step-by-step explanation:
m∠3 = 18°
m∠1 = 90° - 18° = 72°
m∠2 = 180° - 2(72°) = 36°
m∠4 = 2(72°) = 144°
Answer:
4
Step-by-step explanation:
g(n) varies inversely with n.
This can be expressed alternatively as \[g(n) = \frac{k}{n}\] where k is a constant value.
Given that when n = 3, g(n) = 8.
This implies, \[8 = \frac{k}{3}\]
Simplifying the equation to solve for k, k = 8 * 3 = 24
Now when g(n) = 6, \[g(n) = \frac{k}{n}\]
\[6 = \frac{24}{n}\]
Calculating the value of n, \[n = \frac{24}{6}\] = 4
So the required value of n is 4.
