7*122 = 854
5*68 = 340
854 + 340 = 1294, closest to 1200.
Answer B is correct.
Answer:
y = 5x
Step-by-step explanation:
The equation for direct variation is y = kx, where k is the factor of variation. So we know that y and x must fit into this formula.
They've given us a y and x value to solve for k.
y = kx
15 = 3k
15/3 = k
<u>k = 5</u>
Plug k back into our equation.
y = 5x
Answer: 80
Step-by-step explanation:
Sin x = cos (90-x)
Like sin 30 = cos (90-30) =cos 60
So
90-x=90-80
Then
X=80
Verify your solution by finding the sum of the angles of sin and cos, it will be 90
Answer:
10 in
Step-by-step explanation:
6² + 8² = c²
36 + 64 = c²
100 = c²
√100 = c
10 = c
