Derrick's Doggie Day Care charges a $12 registration fee plus $5 per hour for pet sitting. Pauline's Pooch Park charges $3 per hour plus an $18 registration fee. Which inequality below can be used to find the number of hours, h, for which the cost of Derrick's Doggie Day Care is at most the cost of Pauline's Pooch Park?
Answer:
the number of hours is >4
Step-by-step explanation:
given data
Derrick's Doggie
$12 registration fee plus $5 per hour for pet sitting.
the total charges for Derrick's Doggie will be
y=12+5h---------------1
Pauline's Pooch Park charges $3 per hour plus an $18 registration fee.
the total charges for Derrick's Doggie will be
y=18+3h---------------2
equating 1 and 2 we can solve for h which is the number of hours
12+5h=>18+3h
12-18=3h-5h
-8=-2h
h=8/2
h=>4
The average of Landry’s test scores must be at least 92 for her to make an A in Algebra class. She got a 95 on her first test. What grade can Landry get on her second test to make an A in the class?
Average is determined by the sum of test scores divided by total number of tests. This can be represented in this equation:
95 + X / 2 = 92 ⇒ Multiply both sides by 2 to get of the divided by 2
95 + X /2 (2) = 92 (2)
95 + X = 184 ⇒ Subtract 95 from both sides to isolate x
95 -95 + X = 184 -95
X = 89
Therefore, they must get at least 89% to maintain an A.
John lost 1.44 after a week of exercise. One kilogram is equal to approximately 2.2 pounds. Which measurement is closest to the number of pounds that john lost?
Given :
John lost 1.44 kg after a week of exercise.
One kilogram is equal to approximately 2.2 pounds.
To Find :
Which measurement is closest to the number of pounds that john lost.
Solution :
1 kg = 2.2 pounds .
Let, John lost x pounds.
x = 2.2 × 1.44 pounds
x = 3.168 pounds
Therefore, the number of pounds that john lost is 3.168 .
Hence, this is the required solution.

Step-by-step explanation:
correct on edge 2020.
Answer:
Find the midpoint of the segments which connect their houses.
Step-by-step explanation:
If you find the midpoint between all of their houses, then that midpoint represents where they will meet up. And that is indeed what you are trying to find, you are trying to find.. the midpoint.
Therefore A is the correct answer.

Bill has
WIN
of his pizza left from lunch. If he eats
7
more of the pizza, how much pizza is left pls answer I need help
Answer:
Option D) 5/21 pizza is left.
Step-by-step explanation:
Bill has 2/3 of his pizza left from lunch. If he eats 3/7 more of pizza then we have calculate the pizza left.
Let the size of a pizza is x. Now 2x/3 pizza is left with Bill after lunch.
Therefore pizza eaten by Bill = x - 2x/3 = x/3
Now Bill eats 3/7 more of pizza has been eaten by Bill.Therefore total pizza left is
x - x/3 - 3x/7 = x(1 - 1/3 - 3/7) = x( 21 - 7 - 9)/21 = 5x/21
So 5/21 part of pizza is left.

y= -2/5X - 2
slope=
y-intercept=
9514 1404 393
Answer:
slope = -2/5y-intercept = -2Step-by-step explanation:
Compare your equation ...
y = (-2/5)x +(-2)
to the slope-intercept form ...
y = mx + b . . . . where m is the slope and b is the y-intercept.
Matching these patterns, you should be able to see that ...
m = -2/5 = slope
b = -2 = y-intercept
Determine if (4, -5) is a solution of the equation y=12x−7. Explain how you made your decision.
On a farm, a cow eats about 24 pounds of hay per day. If hay costs $1.55 per pound, how much does it cost to feed a cow each day?
Answer:
$37.20 per day
Step-by-step explanation:
Since $1.55 is the amount per pound you would multiply 1.55 x 24 to get 37.5 and since it is money you would add a zero at the end, it would look like so,
$37.20
Hope that helps and have a great day!
Answer:37.2
Step-by-step explanation:
so first you do 24 since its the pounds and since that's for a whole day so if you do a 24 times 1.55 which is 37.2 i hope this helps and can i get the brainiest
-1/2 divided by what = -7/3
3/14
yan na yung answer sana maka tulong
Answer:
(3/14)
Step-by-step explanation:
(-1/2)/x = (-7/3)
(-1/2) = (-7/3)x
(-3/6) = (-14/6)x
(-3/6) = (-14/6)(3/14)
(-3/6) = (-42/84)
(-1/2) = (-1/2)
(-1/2)/x = (-7/3)
(-1/2)/(3/14) = (-7/3)
(-1/2) x (14/3) = (-7/3)
(-14/6) = (-7/3)
(-7/3) = (-7/3)
A family is saving up for a house payment. If they deposit $400 each month into an account that pays 4.8%intrest compounded monthly how much money will they have in 8 years from now
Answer:
44,956
Step-by-step explanation:
Future value
A family is saving up for a house payment. If they deposit $400 each month into an account that pays 4.8% interest compounded monthly how much money will they have in 8 years from now
The formula =
P = d( (1 + r/k)^nk - 1)/r/k
d = Amount deposited monthly = $400
r = interest rate = 4.8% = 0.048
k = compounding frequency = 12 months
n = number of years = 8
P = 400((1 + 0.048/12)^8 × 12 - 1)/0.048/12
P = (400 ( 1 + 0.004)^96 - 1)/0.004
P = (400 ( 1.4495569791 - 1)/0.004
P = 40(0.4495569791)/0.004
P = 179.82279162/0.004
P = 44955.697906
Approximately
P = 44,956

Answer:<
Step-by-step explanation:the square root of 11 is 3.3 and that is less than 4
Answer:
<
Step-by-step explanation:
We can solve this easily by simply converting 4 to the root of its square. 4 squared is 16, and root 16 gives back 4 so the value remains the same.
[tex]4 = \sqrt{16 } \\ [/tex]
Now, we can compare the two values. As 11<16, the same will hold true for its square roots.
So your final answer would be <.
Hope this helps! :D

10x+28−3x=7x+38 Does this equation have one solution, infinitely many solutions, or no solutions? Explain your answer.
Answer:
No solution
Step-by-step explanation:
First we have to solve the equation;
10x + 28 - 3x = 7x + 38
Collect like terms;
7x + 28 = 7x + 38
Subtract 7x from both sides;
28 ≠ 38
No solution, because the number does not equal each other.

1/4 OF MY POINTS For this assignment, you will use sinusoids to model mathematical and real-world problems.
Background Information
Data sets that are cyclical, harmonic, oscillating, or periodic can be modeled with sinusoidal functions.
Finding key features such as minimum, maximum, amplitude, period, and frequency are helpful in

When simplifying 5(−2)(9) − 3, a student first subtracted 3 from 9. Is this the correct first step? Explain.
Answer:
No, you should multiply first.
Step-by-step explanation:
Use PEMDAS. It means parenthesis, exponents, multiplication and division (left to right), and addition and subtraction (left to right). You should multiply 5*-2, then that product *9, then subtract 3. Hope this helps! :)

Lee's uncle is installing a new pool in his backyard. The pool is a square and has an area of 121ft^2. He decides to build a 4 ft wide deck to surround the pool. What is the outside perimeter of the deck? The small square is the pool and the deck is the big square
Answer: 76 feet
Step-by-step explanation:
Given: The pool is a square and has an area of [tex]121ft^2[/tex].
We know that , area = side²
⇒ side= √area
⇒ side= √121=11 feet
Width of deck =4 feet
Length of deck around pool = 11+4+4 = 19 feet
Outside perimeter of deck = 4 (19) = 76 feet [since perimeter of square = 4 (side)]
Hence, Outside perimeter of deck = 76 feet
Use the following information to complete parts I, II and III.
1 hour = 3,600 seconds
1 year = 31,556,952 seconds
Part I: Use scientific notation to estimate the number of hours in one year.
Part II: Use scientific notation to calculate the exact number of hours in one year.
Part III: In two or more complete sentences, compare your answers to parts I and II. In your comparison, discuss similarities and differences in your answers.
Answer:
Part I: Use scientific notation to estimate the number of hours in one year
Using the conversion factors
Estimate using scientific notation
31,556,952 seconds = 3.2 * 10^7
3600 seconds = 3.6 * 10 ^2
1 year = 3.2 * 10^7 seconds * 1 hour/ 3.6 * 10 ^2 seconds
3.2 /3.6 =.88888 (repeating)
10^7 / 10^2 = 10^5
8.88888 * 10 ^5
8.888 * 10 ^4 hours
Part II: Use scientific notation to calculate the exact number of hours in one year.
31,556,952 seconds = 3.1556952 * 10^7
3600 seconds = 3.6 * 10 ^2
1 year = 3.1556952 * 10^7 seconds * 1 hour/ 3.6 * 10 ^2 seconds
3.1556952 /3.6 =.876582
10^7 / 10^2 = 10^5
.876582 * 10 ^5
8.76582*10^4 hours
Part III: In two or more complete sentences, compare your answers to parts I and II. In your comparison, discuss similarities and differences in your answers.
Part II is an exact answer, where Part I is an estimate. Both Parts give values in the thousands of hours, and are both between 8700 and 8900 hours. Part I can be done without a calculator where Part II is much harder to do without a calculator.
