Answer:
C ≈ 95.7°
Step-by-step explanation:
Law of cosines:
c² = a² + b² − 2ab cos C
where a, b, and c are the sides of the triangle, and C is the angle opposite of side c.
9² = 5² + 7² − 2(5)(7) cos C
81 = 25 + 49 − 70 cos C
81 = 25 + 49 − 70 cos C
7 = -70 cos C
-1/10 = cos C
C ≈ 95.7°

Answer:
The value of "x" is 5.
Step-by-step explanation:
In order to solve this system of equations, we first have to take the first equation and use it to represent "y" in terms of "x". We do that in the following way...
Now, we need to take the second equation and substitute "y" for the equivalent value in terms of "x". After doing this we will get the following equation, which we can solve to get the value of "x".
Therefore, the value of "x" is 5.

Hi there!
Your answer is: 150 people prefer that school assemblies be held on Friday afternoon
Step-by-step explanation:
3 out of 4 students means that 75% of students prefer assemblies on Friday afternoon!
To find 75% of 200:
200 = 100%
/100 to find 1%
2 people = 1%
Multiply it by 75 to determine 75%
2×75= 150
150people is 75% of 200 people!
I hope this makes sense! Let me know if you have questions!
Answer:
3/5
Step-by-step explanation:
To find the slope of the given line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line y=-5/3x+7 is m = 3/5. Step 2: Use the slope to find the y-intercept.
