a landscape company charges $100 plus $15 per hour. another company charges $75 plus $17 per hour. how long is a job that costs the same no matter which company is used
To find when the job cost is the same for both companies, equate their cost equations. By solving 100 + 15h = 75 + 17h, we find that at 12.5 hours the job would cost the same no matter which company is used.
To determine when a job costs the same for both landscape companies, we need to equate the two cost equations they offer and solve for the number of hours.
Let h be the number of hours the job takes. The first company's cost can be represented as C1 = 100 + 15h, and the second company's cost as C2 = 75 + 17h. To find the number of hours when both companies charge the same amount, we set C1 = C2:
100 + 15h = 75 + 17h.
Rearrange the equation to solve for h:
100 - 75 = 17h - 15h
25 = 2h
h = 12.5 hours.
So, a job that takes 12.5 hours would cost the same amount whether it is done by the first company or the second company.

name all planes intersecting plane CHG
Answer:
b. CBA, CDI, FIH, BAF
Step-by-step explanation:
In the given figure of a cuboid. The total number of plans is 6.
These planes are, plane ADI, plane CBA, plane CDI, plane FIH, plane BAF and plane CHG. But in the cube plane ADI and plane CHG is parallel to each other, therefor they do not intersect each other and rest plane (other then plane ADI ) are not parallel to the plane CHG, so these planes intersect the plane CHG.
Hence we say that the plane CBA, Plane CDI, plane FIH and plane BAF are the intersecting plane of the plane CHG.

There are 52 playing cards in a deck, and 4 of them are aces. The probability of turning over an ace is 4/52
B. Kenny rolled a number cube 9 times and got 4 even numbers. The probability of an even number is 4/9
C. Wendy flipped a coin 5 times, and the results were 4 tails. The probability of tails is 4/5
D. There were 73 people in a grocery store, and 45 of them bought milk. The probability of people buying milk is 45/73
Answer:
Option A and D are correct Option.
Step-by-step explanation:
Theoretical Probability: Probability based on reasoning written as a ratio of the number of favorable outcomes to the number of possible outcomes.
that is [tex]Probability=\frac{Number\:of\:favorable\:outcome}{Total\:Number\:of\:outcome}[/tex]
Option A:
Number of favorable outcome = 4
Total number of outcome = 52
[tex]Probability=\frac{Number\:of\:favorable\:outcome}{Total\:Number\:of\:outcome}=\frac{4}{52}[/tex]
Thus, This is an example of Theoretical Probability.
Option B:
Number of favorable outcome = [tex]^9C_4\times3^4\times3^5=2480058[/tex]
Total number of outcome = [tex]6^9=10077696[/tex]
Thus, This is not an example of Theoretical Probability.
Option C:
Number of favorable outcome = [tex]^5C_4=5[/tex]
Total number of outcome = [tex]2^5=32[/tex]
Thus, This is not an example of Theoretical Probability.
Option D:
Number of favorable outcome = [tex]45[/tex]
Total number of outcome = [tex]73[/tex]
[tex]Probability=\frac{Number\:of\:favorable\:outcome}{Total\:Number\:of\:outcome}=\frac{45}{73}[/tex]
Thus, This is an example of Theoretical Probability.
Therefore, Option A and D are correct Option.
Liability insurance covers bodily injury to others and any property damaged, including yours.
True
False
Liability insurance covers bodily injury to others and any property damaged, including yours. This statement is TRUE.
There are several types of liability insurance. Auto liability insurance covers the damages that you've created to someone else's car and bodily injury.
Final answer:
The statement is false because liability insurance does not cover the policyholder's property damage, but it does cover bodily injuries to others and damage to others' property. Personal property would require additional coverage, such as collision, comprehensive, or homeowner's insurance.
Explanation:
The statement 'Liability insurance covers bodily injury to others and any property damaged, including yours' is false. Liability insurance is primarily designed to cover bodily injury to others and property damage for which you are legally responsible. This includes, for instance, if someone is injured on your property, or if you are responsible for an accident that causes damage to another person's car or property. However, it does not cover your own property damage. For damage to your own property, you would need collision or comprehensive coverage as part of your automobile policy, or a homeowner's insurance policy with coverage for personal property.
Homeowner's insurance typically includes liability coverage to protect you if someone gets injured on your property, as well as various forms of property insurance against risks like fire, theft, and natural disasters, but it may exclude illegal activities. Car insurance also requires at a minimum liability coverage, and can have additional options such as uninsured motorist coverage, which protects you if the other driver is at fault and has no insurance.

Write a word phrase to represent the numerical expression 4+(27-10)
In linear equation ,the numerical expression would be four plus the difference of 27 and 10.
What are instances of linear equations?Ax+By=C represents a two-variable linear equation in its standard form. A standard form linear equation is, for instance, 2x+3y=5.Finding both intercepts of an equation in this form is rather simple (x and y).When resolving systems of two linear equations, this form is also incredibly helpful.A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.given numerical expression = 4 + (27 - 10)
so,
4 + (27 - 10)
It should be the sum of 4 and a difference of 27 and 10

the description of a TV is based on the diagonal length. if the height of a TV is 10 inches and the width is 7 inches, what is the approximate diagonal length in inches?
The Pythagorean theorem states that the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
The approximate length of the diagonal is 12 inches.
What is Pythagorean theorem?The square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
We have,
Height = 10 inches
Width = 7 inches
Height and width can be considered as the other two sides.
Now,
The diagonal length can be considered as the hypotenuse.
Now,
Diagonal² = 10² + 7²
Diagonal² = 100 + 49
Diagonal² = 149
Diagonal = √149
Diagonal = 12.206 inches
The approximate diagonal length will be 12 inches.
Thus the approximate length of the diagonal is 12 inches.

Gabriella bought three cantaloupes for $7. How many cantaloupes can Shayna buy if she has $21?
Shayna can buy 9 cantaloupes with $21.
Explanation:To calculate how many cantaloupes Shayna can buy with $21, we need to find out the price of one cantaloupe. Since Gabriella bought three cantaloupes for $7, we can find the price of one cantaloupe by dividing $7 by 3. 7 divided by 3 is $2.33, rounded to the nearest cent. Now, to find out how many cantaloupes Shayna can buy, we need to divide $21 by $2.33. $21 divided by $2.33 is 9, with a remainder of $0.78. Since we can't buy part of a cantaloupe, Shayna can buy 9 cantaloupes.
Final answer:
The price per cantaloupe is $2.33. With $21, Shayna can buy approximately 9 cantaloupes.
Explanation:
To answer how many cantaloupes Shayna can buy with $21, we first need to determine the price of one cantaloupe from the information given. Gabriella bought three cantaloupes for $7. Therefore, the price per cantaloupe is $7 divided by 3 cantaloupes, which equals $2.33 per cantaloupe (rounded to two decimal places).
Next, we can calculate how many cantaloupes Shayna can buy with her $21 by dividing her total amount of money by the price of one cantaloupe. So $21 divided by $2.33 per cantaloupe equals approximately 9 cantaloupes (rounding down since you cannot buy a fraction of a cantaloupe).
