One possible solution is 10 hours of tutoring and 3 hours of landscaping.
<h3>
Inequality</h3>
Inequality is an expression used to show the non equal comparison of two or more numbers and variables.
Let x represents the number of hours tutoring and y represents the number of hours landscaping
From the question, we form the equations:
- x + y ≤ 13 (1)
- 18x + 9y > 180 (2)
A possible solution is (10, 3)
One possible solution is 10 hours of tutoring and 3 hours of landscaping.

Answer:
Simplifying
1 + -10x = 81
Solving
1 + -10x = 81
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + -10x = 81 + -1
Combine like terms: 1 + -1 = 0
0 + -10x = 81 + -1
-10x = 81 + -1
Combine like terms: 81 + -1 = 80
-10x = 80
Divide each side by '-10'.
x = -8
Simplifying
x = -8
Step-by-step explanation:
Answer: simple random sampling
Step-by-step explanation:
- A simple random sampling is a sampling method in which individuals are chosen randomly from the population. In this each individual has equal chances to get selected.
- If N is the population size , then for any individual , the chances for getting selected is
.
As per given , the company randomly selects 50 customers directly from the database without applying any further steps and asks them about their level of satisfaction with the company.
Thus , the sampling technique used here is simple random sampling.
Since angle C is not 90 degrees, it's one of the acute angles
in the right triangle.
(The side adjacent to angle C ) divided by (hypotenuse)
is the cosine of angle C .
(adjacent) / (10 inches) = cos(40 degrees)
Multiply each side by (10 inches):
Adjacent side = (10 inches) x cos(40) =
(10 inches) x 0.766 =
7.66 inches (rounded)
0.00067
You always want the period to the right of the first number meaning you’ll start from there counting backwards because it is negative.
