Answer is b hope this helps
Answer:
D
Step-by-step explanation:
A. Sin 42=0.669
Cos=52=0.617
B. Sin 90=1
cos 90=0
C. cos30=0.866
sin 70=0.940
D. sin80=0.985
cos 10=0.985
75m + 800 = 95m + 500
Solve that equation
Which should get you m=15
15 is your answer
Answer:
50.6
Step-by-step explanation:
The perimeter of the circle is 12.56 because we take 1/2 of 8 (the length of the short side of the rectangle) and multiply that by pie (or 3.14). Now that we know that the perimeter of the circle is 12.56 we add that to 8 (short side of the rectangle) and we add that to 15 twice (which is 30)
Answer:
17 and 5
Step-by-step explanation:
Interesting question!
Turn both sentences to equations:
![a=4b-3\\a-2b=7](https://tex.z-dn.net/?f=a%3D4b-3%5C%5Ca-2b%3D7)
a is the first number, and b is the second number.
A system of equations! A graphing calculator will do the work:
(See picture)
The y in the picture is a, and the x in the picture is b.
So the solution is a=17 and b=5
