Two complementary angles sum is 90 degrees.
Angle 1 = x
Angle 2 = 2x ( two times angle 1)
Equation: x + 2x = 90
Solve:
Combine like terms:
3x = 90
Divide both sides by 3:
X = 90/3
X = 30
Angle 1= 30
Angle 2 = 60
Answer:
x-4y=4
Step-by-step explanation:
The equation of a straight line is in slope intercept form:
y = mx + b;
where y and x are variables, m is the slope of the line and b is the y intercept.
The standard form of a line is:
Ax + By = C
where A, B and C are constants, x and y are variables
The equation of a straight line passing through the points (x₁, y₁) and (x₂, y₂) is given by:
![y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\](https://tex.z-dn.net/?f=y-y_1%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%28x-x_1%29%5C%5C)
Given that a line passes through the points (0, -1) and (4, 0), the equation of the line is given by:
![y-(-1)=\frac{0-(-1)}{4-0} (x-0)\\\\y+1=\frac{1}{4} x\\\\y=\frac{1}{4} x-1\\\\4y=x-4\\\\x-4y=4](https://tex.z-dn.net/?f=y-%28-1%29%3D%5Cfrac%7B0-%28-1%29%7D%7B4-0%7D%20%28x-0%29%5C%5C%5C%5Cy%2B1%3D%5Cfrac%7B1%7D%7B4%7D%20x%5C%5C%5C%5Cy%3D%5Cfrac%7B1%7D%7B4%7D%20x-1%5C%5C%5C%5C4y%3Dx-4%5C%5C%5C%5Cx-4y%3D4)
Answer: A minimum of 5 people will be needed.
Step-by-step explanation:
150/32 = 4.6875
You can't have a partial person, so round up to 5.
It may be possible to have 4 employees working 32 hours and another working 22 hours, but that is not what the question asks exactly. That is still 5 people.
Answer:
B. 128 in.
Step-by-step explanation:
Just add 48 & 16, then times the answer by 2.
Work:
48 + 16 = 64
64 x 2 = 128
Hope this helps! Brainliest plz?
Answer:
Step-by-step explanation:
So the price is $849 and the tax is 8%
Since the tax is 8%, that means the tax is 8% of the total price, $849 and thus we get the equation:
0.08 * 849 = $67.92
Total price = Price of refrigerator + tax = $849 + $67.92 = $916.92
