Answer:
1.5x+2.75y+33
Step-by-step explanation:
Call x: the hour of dogs keeping
y: the hour of wolves keeping
The total charge for dogs keeping: 19+ 1.5x
The total charge for wolves keeping: 14+2.75y
Total cost (19+ 1.5x)+(14+2.75y)= 1.5x+2.75y+33

The distance from your front door to the mailbox is 18 4/5 meters. The distance from your front door to your basketball hoop is 13 7/10 meters. How much farther from your front door is the mailbox than the basketball hoop?
Answer:
5 1/10 meters
Step-by-step explanation:
18 4/5 can be changed to 18 8/10 so
18 8/10 - 13 7/10 = 5 1/10 meters

Why are the divisibility rules for 2, 3, and 5 very useful for determining prime and composite numbers
1. They are the smallest odd numbers
2. They add up to 10
3. They are prime numbers with nice divisibility rules
4. They multiply to 30
5. They can be multiplied together to make every number
Answer:
option 3.
Step-by-step explanation:
alright, ima explain each option.
1. "smallest odd numbers" 2 is an even number. that's out of the playing field.
2. "add up to 10" sure, they do add up to 10, but finding prime and composite numbers are all about division and multiplication.
3. this is true. 2, 3, and 5 are all prime numbers, and they have the nice divisibility rules. [ for 2, it has to be even, for 5, it has to end in 0 or 5, and 3 has to have the sum of its digits being divisible by 3. ]
4. they do multiply to 30, but this does not help break the composite numbers down.
5. we cannot make every number with just these. we can not multiply any other whole number to get 7 for per example, because it's a prime number.

The sum of two consecutive integers is -92. Find the integers.
Answer:
x = -46.5
x + 1 = -45.5
Step-by-step explanation:
x + x + 1 = -92
2x + 1 = -92
-1 -1
------------------
2x = -93
---- ----
2 2
x = -46.5
x + 1
(-46.5) + 1
-45.5
Answer:
No solution
Step-by-step explanation:
We can set up an equation where x is the integer and x+1 is the next one
x+x+1=-92
2x+1=-92
2x/2=-93/2
x=-46.5
-46.5+1=-45.5
The problem is that integers do no include decimals so there is no possible whole number. This problem would be possible if it was consecutive odd integers.
A monkey is swinging from a tree. On the first swing, she passes through an arc of 10 m. With each swing, she passes through an arc 9/10 the length of the previous swing.
What is the total distance the monkey has traveled when she completes her 25th swing? Round your final answer to the nearest meter.
Answer:
250,000 meters (m)
Step-by-step explanation:
First swing she passed through an arc of:
10m
Each swing, she passed through an arc of :
9/10
9/10×10=10
25×10=250km
250km converted to the nearest m=
250,000 Meters (m)

Currently, Jacob’s mother is three more than nine times as old as Jacob. In eleven years, his mother will be five more than three times his age. Write a system of linear equations that models this situation. Let j represent Jacob's age, and let m represent his mother's age.
Write an equation that relates Jacob and his mother's current ages. Solve the system of equations.
What are their ages?
Answer:
Jacob is 4 years old and his mother is 40 years old.
Step-by-step explanation:
Part 1: The linear equations are and
Part 2: Solving the equations, we have, and
Part 3: Jacob is 4 years old and his mother is 40 years old.
Explanation:
Part 1: Let j represent Jacob's age, and let m represent his mother's age.
It is given that, "Jacob's mother is three more than nine times as old as Jacob". Writing it as linear equation, we have,
It is also given that, "In eleven years, his mother will be five more than three times his age". Writing it as linear equation, we have,
Simplifying this, we get,
Thus, the linear equation is
The linear equations are and
Part 2: Solving the linear equation, we get,
Substituting in
Simplifying, we get,
Hence,
Substituting in
Solving the equations, we have, and
Part 3: Since, j represents jacob and m represents the jacob's mother
Thus, Jacob is 4 years old and his mother is 40 years old.

The speed limit is 55mph. How far can you travel in 3 hours going the speed limit? How far can you travel if you went 5 miles over the speed limit?
Answer:
If you were going the speed limit, after 3 hrs, you would go 165 miles.
If you were going 5 miles above the speed limit you would go 180 miles.
Step-by-step explanation:
55 x 3 = 165
55 + 5 = 60
60 x 3 = 180
Answer:
165miles
180miles
Step-by-step explanation:
If going 55mph for 3 hours,
55miles/hour * 3hour = 165miles
If going 60mph (5 over the limit) for 3 hours:
60miles/hour * 3hour = 180miles
Greg purchased n notebooks. They were 4 dollars each. Write an equation to represent the total cost c that Greg paid.
Answer:
c = 4n
Step-by-step explanation:
The total cost (c) is going to be of the 4 notebooks together
We don't know how many notebooks Greg got, so it's represented by n.
It doesn't matter how many notebooks Greg purchased, because each of them were $4.
So to represent the total cost of the notebooks, you would write c = 4n
Andrea uses 3.12 cups of flour in a recipe that makes 8 key lime cupcakes. Corey uses 2.52 cups of flour in a recipe that makes 7 key lime cupcakes. How much more flower per cupcake is needed for Corey’s recipe?
I will give Brian list plz help
Answer:
The Answer is 0.03
Step-by-step explanation:
Andrea = 3.12/8 flower per cupcake
3.12/ 8 = .39
Corey = 2.25/ 7 flower per cupcake
2.25/ 7 = .36
So Corey's recipe needs
( 0.39 - 0.36) = 0.03 flower per cupcake

x=width of pool
2x=length of pool
the dimensions of the rectangle forming the walkway and the pool are x+4 and 2x+4
the area of this rectangle minus the area of the pool is 196 square feet
(2x+4)(x+4)-(x)(2x)=196
2x^2+4x+8x+16-2x^2=196
combine similar terms
12x+16=196
12x=196-16
12x=180
x=180/12
x=15 feet is the width of the pool
check: 34*19-30*15=196
646-450=196
196=196

what is the gradient?
Answer:
[tex]{ \tt{gradient = \frac{ - 3 - 1}{0 - ( - 1)} }} \\ = \frac{ - 4}{1} \\ = - 4[/tex]
Answer:
The gradient (slope) is -4.
Step-by-step explanation:
Note that two points on the graph through which the blue line passes exactly are (-2, 5) and (0, -3). As we move from the first point to the second, x increases by 2 (the 'run') and y (the 'rise') decreases by 8. Thus, the gradient, or slope, of this line is m = rise/run = -8/2, or m = -4.

90, degrees about the origin.
Answer:
See explanation
Step-by-step explanation:
From the question, we understand that the quadrilateral is rotated by 90 degrees about the origin.
The question is incomplete; so, I will give a general explanation.
The rule for 90 degrees rotation about the origin is:
[tex](x,y) \to (-y,x)[/tex]
For instance:
A point (4,6) will become (-6,4) after rotation.

Answer:2 and 3
Step-by-step explanation:
Can someone please help me with this question I need to find the unit rate.
First we have to take any point, I'll take (5,3).
X-axis represents number of pounds and y-axis represents total cost (in $).
So, 5 pounds = $3
=> 1 pound = $3/5
=> 1 pound = $0.6
=> 1 pound = 60 cents
Answer:
60c per pound.
Step-by-step explanation:
If 5lbs cost 3 dollars, 1lb = 3/5
3/5 = 0.6$
60c

Elliot has been running a lawn care business since 2000. He cuts grass, trims, and weed whacks yards for his customers throughout the season. Each year, he has increased his fee by the same amount. The table shows what Elliot charged each customer for two given years of his business:
Year Lawn Care Fee
2000 $750
2010 $1350
A. What is the rate of change and initial value for Elliot’s business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Elliot charges each year.
Answer:
Rate of Change: $60 Per year
Step-by-step explanation:
We can find how many years are from 2000 to 2010 not overcouting. That is 10. Now, we do 1350 minus 750 because that's the change of the fee. That will give you 600. Now, 600 divided by 10, giving you how much change each year. That's 60.
So,
2000:750
2001:810
2002:870
2003:930
2004:990
2005:1050
2006:1110
2007:1170
2008:1230
2009:1290
2010: 1350
You can graph it out with that, now.
