Answer:
Profit earned by Randi on her last snow shoveling and salting job= $ 60
Let number of hours spent by Randi on that day while working as a shoveler and salter = x hours
Writing the statement in terms of inequality
→ Number of hours worked= Amount of profit earned
→ x=60
→If profit is less than $60.00, then Number of hours will be less.
→If Profit is more i.e greater than $60.00, Number of hours will be more.
Answer:
Step-by-step explanation:
Remark
2 angles are complementary means that 2 angles add up to 90°. That is the guiding princeple behind the problem.
Givens
Let the smallest angle = x
Let the largest angle = 4x + 30
Equation
4x + 30° + x = 90° Combine like terms on the left
Solution
5x + 30 = 90 Subtract 30 from both sides.
5x + 30 - 30 = 90 - 30 Combine
5x = 60 Divide both sides by 5
5x/5 = 60/5
x = 12
Answer
- smallest angle = 12
- Larger angle = 4*12 + 30 = 78
Answer: Company A would be a better deal for number of minutes over 200
Step-by-step explanation:
Let x represent the number of minutes that you would use with either company A or company B.
Company A has a monthly charge of $10 plus 5¢ a minute for each minute of long distance calls. It means that the cost of x minutes of long distance call is
10 + 0.05x
Company B has a monthly charge of $8 plus 6¢ a minute for long distance calls. It means that the cost of x minutes of long distance call is 10 + 0.05x
8 + 0.06x
For Company A to be a better deal, it means that
10 + 0.05x < 8 + 0.06x
10 - 8 < 0.06x - 0.05x
2 < 0.01x
0.01x > 2
x > 2/0.01
x > 200
Similar triangles may or may not have congruent sides lengths
<h3>How to determine the measurements of the objects</h3>
From the properties of similar triangles, the side lengths of similar triangles may or may not be congruent, but the side lengths are always proportional.
Take for instance, an equilateral triangle has a dimension of 2cm by 2cm by 2cm
The similar triangles could have the following dimensions:
- 3cm by 3cm by 3cm
- 4cm by 4cm by 4cm
- 6cm by 6cm by 6cm
- 7cm by 7cm by 7cm
- 10cm by 10cm by 10cm
This is so because the triangles are proportional to the equilateral triangle
