sorry that I can't get 2, 4, 6 and 8 I haven't done this type of math in a while
M∠1 + m∠2 + m∠3 = 360
y + 110 + 90 = 360
y + 200 = 360
- 200 - 200
y = 160
It is the answer because it shows that the first one is 110 degrees and the second one 90 degrees, making a total of 200 degrees; since the angles have a total of 360 degrees, the value of y is 160 degrees.
Direct variation: y = kx
Inverse variation: y = k/x
y varies directly with x^2 ... : y = kx^2
... and inversely with z: y = kx^2/z
Now we use the given information to find k.
x = 2, z = 6, y = 2 6/11
y = kx^2/z
2 6/11 = k * (2^2)/6
28/11 = 4k/6
28/11 = 2k/3
k = 28/11 * 3/2
k = 84/22 = 42/11
Now we can use our value of k in the function.
y = kx^2/z
y = (42/11)(x^2/z)
Now we use our function to find y when x = 1 and z = 3.
y = (42/11)(x^2/z)
y = (42/11)(1^1/3)
y = 42/33
y = 14/11
y = 1 3/11
Answer:
$20.54
Step-by-step explanation:
Happy Helpers Maid Service's payroll tax expense of 14% should only be applied to the direct labor rate ($11) and not to the incurred costs for sick-days and vacations. Therefore, the standard rate per direct labor hour (S) is given by the sum of the direct labor rate (including taxes) and incurred costs:
