Answer:
c = 24.34
Step-by-step explanation:
Here, we can use the cosine rule
Generally, we have this as:
a^2 = b^2 + c^2 - 2bcCos A
12^2 = 14^2 + c^2 - 2(14)Cos 19
144 = 196 + c^2 - 26.5c
c^2 - 26.5c + 196-144 = 0
c^2 - 26.5c + 52 = 0
We can use the quadratic formula here
and that is;
{-(-26.5) ± √(-26.5)^2 -4(1)(52)}/2
(26.5 + 22.23)/2 or (26.5 - 22.23)/2
24.37 or 2.135
By approximation c = 24.34 will be correct
Answer:
They bought 6.24 pounds of hamburger meat
Explanation:
We are given that:
The first friend brought 2.7 pounds of hamburger meat
The second friend brought 3.54 pounds of hamburger meat
The total amount of hamburger meat they both brought would be simply the summation of what they brought individually.
This means that:
Total amount brought = 2.7 + 3.54
Total amount brought = 6.24 pounds of hamburger meat
Hope this helps :)
divide the temperature by the number of hours
36/12
answer: 3 degrees
Step-by-step explanation:
2x + 2y = -2.............equation 1
3x - 2y = 12..............equation 2
Solving both equations we get
2x + 2y = -2
<u>3x </u><u>-</u><u> </u><u>2y </u><u>=</u><u> </u><u>1</u><u>2</u>
5x = 10
Therefore x = 2
Now putting x = 2 in equation 1
2 * 2 + 2y = -2
4 + 2y = -2
2y = -2 -4
2y = -6
Therefore y = -3
