You decide to start a dog walking business and are trying to plan how much you to charge. You determine that you can only walk 5 dogs at the most at any given time. You also decide to charge in 30 minute intervals and, due to your schedule, you can only walk for 3 hours a day. Based on those conditions, what is the most amount of dogs that you can walk in a given day?
Answer:
The most amount of dogs that you can walk in a given day is 30 dogs.
Step-by-step explanation:
You decide to charge in 30 minute intervals, and due to your schedule you can only walk 3 hours a day. Then you must know how many intervals of walks you can do in those 3 hours a day that you can walk. Being 1 hour equal to 60 minutes, then 30 minutes equals 2 intervals in 1 hour. Then you can apply the following rule of three: if in 1 hour there are 2 intervals of 30 minutes, in 3 hours how many intervals of 30 minutes are there?
[tex]amounts of intervals=\frac{3hours*2 intervals}{1 hour}[/tex]
amount of intervals= 6 intervals
You determine that you can only walk a maximum of 5 dogs at a given time, that is, in each interval you can walk a maximum of 5 dogs. Then you can apply the following rule of three: if in 1 interval you walk a maximum of 5 dogs, in 6 intervals how many dogs do you walk a maximum?
[tex]amounts of dogs=\frac{5 dogs*6 intervals}{1 interval}[/tex]
amount of dogs= 30 dogs
The most amount of dogs that you can walk in a given day is 30 dogs.

Find the equation of the line passing through the point (-1, -2) and perpendicular to
the line y = -1/2x + 5.
A) y = 2x
O B) y = -1/2x - 5/2
O C) y = -1/2x
OD y = 1/2x - 5,2
Answer:
A) y = 2x
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals.
The given line has slope -1/2.
The negative reciprocal of -1/2 is 2.
The only choice with slope = 2 is choice A.
y = 2x does include point (-1, 2).
Answer: A) y = 2x

C.0.90x=45.5
D. 1.10x+2.5=45.5
E. 2(x-0.10x+2.5)=91
Answer:
B. 0.90x=43
E.2(x-0.10x+2.5)=91
Step-by-step explanation:
Given equation:
x-0.10x+2.5 = 45.5
Let us simplify this;
Collect like terms;
x - 0.10x = 45.5 - 2.5
Simplify;
0.9x = 43 (Option A)
Also;
x-0.10x+2.5 = 45.5
Simplify by multiplying both sides by 2;
2(x - 0.10x + 2.5) = 2(45.5)
2(x - 0.10x + 2.5) = 91.0
Also;
x-0.10x+2.5 = 45.5
0.9x + 2.5 = 45.5

A farmer created a crop circle that is a square inside a circle. The square contains the crop of wheat, and the part outside the square is flat. The circle has a radius of 25meters, and the square has a side length of 35 meters. What is the area of the flat region within this crop circle? Use 3.14.
Answer:
738.75m^2Step-by-step explanation:
this problem is on the mensuration of flat shapes.
first, we need to solve for the area of the circle
area of circle= πr^2
area of circle= 3.142*25^2
area of circle= 3.142*625
area of circle= 1963.75m^2
the area of the square
area of square= l^2
area of square= 35^2
area of square= 1225m^2
the area of the flat region within this crop circle is
area of circle-area of square
= 1963.75-1225
=738.75m^2
The point-slope form of the equation of the line that passes through (-9, -2) and (1, 3) is y – 3 = {(x - 1). What is the
slope-intercept form of the equation for this line?
Oy=1x+2
Oy={x-4
O y = x + 3/2
Oy=2x-
2.
Option A is the correct answer, y = x + 2
y - 3 = x-1
If you bring the 3 to the R.H.S, it becomes y = x + 2
If you substitute the values,
3 = 1 + 2
3 = 3
Thus, e equation is correct
The slope-intercept form of the equation for this line is y = 1/2 x + 5/2
First, we need to get the slope of the equation passing through the coordinate (-9, -2) and (1, 3)
m = 3+2/1+9
m = 5/10
m = 1/2
The equation in point slope form is given as y - 3 = 1/2(x - 1)
2(y - 3) = x - 1
Write in slope intercept form
2(y - 3) = x - 1
2y - 6 = x - 1
2y = x + 5
y = 1/2 x + 5/2
Hence the slope-intercept form of the equation for this line is y = 1/2 x + 5/2

Luke opened a savings account with a balance of $0.00 and deposited $20.00. During the next 2 weeks, he made two more deposits for $15.00 and $35.00. At the end of the month, he made a withdrawal that brought his balance back to $0.00. Assuming no interest was earned, how much money did Luke withdraw from his savings account?
Answer:
85$ was withdrawed.
Step-by-step explanation:
20 + 30 + 35 = 85 - 85 = 0
Answer:
Okays so Luke deposited $20.00, $15.00, and $35.00 so we can make the equation
$20.00 + $15.00 + $35.00 = $70.00
At the end of the month he withdrawaled all of his money which brought it back to $0.00. That means that Luke withdrawled $70.00 from his bank account!

volume =160.875m, length =6.5m, height =5.5m, breadth =?
Answer:
b = 4.5 m
Step-by-step explanation:
Since we have 2 sides of the shape and the total volume, we can easily find the measurement of the third side which is the breadth by:
volume = 160.875
v = l×h×b
160.875m=(6.5m)×(5.5m)×b
160.875m=35.75b
b = 4.5 m
Answer:
4.5m
Step-by-step explanation:
v=lbh
b=v/lh
= 160.875/(6.5×5.5)
=160.875/35.75
=4.5m

Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long. A customer came in during the morning and bought 120 centimeters of the velvet. Another customer bought an additional 14 meters during the afternoon. How much crimson velvet does Malik's shop have left? Write the answer in centimeters. centimeters of velve
Given:
Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long.
Velvet purchased by first customer = 120 centimeters
Velvet purchased by second customer = 14 meters
To find:
The remaining velvet in Malik's shop.
Solution:
We know that,
1 meter = 100 cm
Using this conversion, we get
32 meter = 3200 cm
14 meter = 1400 cm
Now,
Remaining velvet in Malik's shop = (3200 - 120 - 1400) cm
= 1680 cm
Therefore, the remaining velvet in Malik's shop is 1680 cm.

Your sister is selling Girl Scout cookies that cost $3.50 per box. Your family bought 6 boxes. How many more boxes of
cookies does your sister need to sell to raise $196?
Answer:
She needs $175.
Step-by-step explanation:
3.50 X 6= $21. (196-21=175)
So since she needs $196 and per box it would be $3.50 and 6 boxes is $21 total, she would need to sell 56 boxes total to get to her goal, but since her parents bought 6 boxes already she will only need 50 more.

If α , β are roots of x2 + 5x + a =0 and 2α + 5β = -1 then α is equal to _____?
9514 1404 393
Answer:
-8
Step-by-step explanation:
If α and β are roots of x^2 +5x +a = 0, then we must have ...
(x -α)(x -β) = x^2 +5x +a
x^2 -(α+b)x +αβ = x^2 +5x +a
Then ...
α + β = -5
Together with the other relation between the roots, we have a system of equations in α and β.
Using the above to write an expression for β, we get ...
β = -α -5
Substituting this into the given relation, we have an equation for α:
2α +5(-α -5) = -1
-3α -25 = -1 . . . . . . eliminate parentheses
-24 = 3α . . . . . . . . add 3α +1
-8 = α
The root α is equal to -8.

The following is a factor of the polynomial is x+2.
What is Factor theorem?Factor theorem is a special kind of the polynomial remainder theorem that links the factors of a polynomial and its zeros.
The factor theorem removes all the known zeros from a given polynomial equation and leaves all the unknown zeros. The resultant polynomial has a lower degree in which the zeros can be easily found.
As per the factor theorem, (y – a) can be considered as a factor of the polynomial g(y) of degree n ≥ 1, if and only if g(a) = 0. Here, a is any real number. The formula of the factor theorem is g(y) = (y – a) q(y). It is important to note that all the following statements apply for any polynomial g(y):
(y – a) is a factor of g(y).g(a) = 0.The remainder becomes zero when g(y) is divided by (y – a).The solution to g(y) = 0 is a and the zero of the function g(y) is a.Given:
f(x)=x³ + 12x² + 9x - 22
To the above equation (x + 2) is a factor of x³ + 12x² + 9x - 22.
As,
f(-2)= (-2)³ + 12(-2)² + 9(-2) - 22
f(x)= -8 + 48 -18 -22
f(x)= 40 -40
f(x) = 0
Hence, the factor of x+2
