Answer:

total=quantity*price per item on that row

New account balance=old account balance plus total on that row

Step-by-step explanation:

I won't do all of the rows but I will do a couple and explain to you how I got the answer and how you should too:

The total for each row is equal to that row's price per item times that row's quantity.

The amount balance is going to include previous account balance into it. So once you find the total for that row you will take previous account balance and add it to the previous account balance (We are doing adding instead of subtracting because the number we are getting is negative for the total.)

So example:

Second row total is 2(-45.25)=-90.50 so that is what we are adding to 2500.68 or we are subtracting 90.50 from 2500.68 giving us 2410.18

Third row total is 75(-1.39)=-104.25.  Third row account balance is 2410.18-104.25=2305.93.

So again total=quantity*price per item on that row

New account balance=old account balance plus total on that row

If you want me to check your forth row to see if you are doing it right, I will.

Answer:

[tex]m = -4[/tex]

Step-by-step explanation:

[tex]\frac{y2 - y1}{x2 - x1}[/tex]

[tex]\frac{-4 - 8}{2-(-1)}[/tex]

[tex]-4 - 8 = -12\\ 2-(-1)=3[/tex]

[tex]\frac{-12}{3} = -4[/tex]

[tex]m = -4[/tex]

Answer:

M=-4

Step-by-step explanation:

The formula for the slope is:

m=[tex]\frac{y^{2} -y^{1} }{x^{2} -x^{1} }[/tex]

You have two points the first one would be: (-1,8)

So [tex]x^{1}= -1  y^{1}= 8 [/tex]

The second point is: (2,4)

So [tex]x^{2}= 2  y^{2}= 4 [/tex]

Now you just have to put the values inside the formula:

m=[tex]\frac{-4-8)}{2-(-1)}[/tex]

m=[tex]\frac{-12}{3}[/tex]

m=-4

Got Correct On MyPath.

The air conditioning system can circulate approximately 14.44 cubic yards of air per minute.

To convert cubic feet to cubic yards, we need to know that there are 27 cubic feet in one cubic yard. Using this conversion factor, we can find the number of cubic yards of air that the air conditioning system can circulate per minute.

1. Start with the given value of 390 cubic feet per minute.

2. Divide this value by the conversion factor of 27 cubic feet per cubic yard:

390 cubic feet ÷ 27 cubic feet per cubic yard = 14.44 cubic yards

3. Rounding to the nearest hundredth, the air conditioning system can circulate approximately 14.44 cubic yards of air per minute.

In summary, the air conditioning system can circulate approximately 14.44 cubic yards of air per minute.

Answer:

16 centimeters cubed

Step-by-step explanation:

Volume of cone is equal to 1/3 * pi * r^2 * h

We are using 3.14 for pi so I'm going to rewrite my formula for volume.

V=1/3 * 3.14 * r^2 * h

We are given diameter is 3 but we need the radius.  We know the radius is half of the diameter so the radius is 1.5 since that is half of 3.

We are given the height is 7.

V=1/3 * 3.14 * 1.5^2 *7

Put into calculator

V=16.485

The whole number that this is closest to is .... 16

So

The Volume of the cone is approximately 16 centimeters cubed.

Answer: [tex]16\ cm^3[/tex]

Step-by-step explanation:

You can use this formula for calculate the volume of a cone:

[tex]V_{(cone)}=\frac{1}{3}\pi r^2h[/tex]

Where "r" is the radius and "h" is the height of the cone.

To find the radius, you need to divide the diameter by 2. Then:

[tex]r=\frac{3\ cm}{2}=1.5\ cm[/tex]

Knowing the radius and the height ([tex]h=7\ cm[/tex]), you can substitute them into the formula.

Therefore, the volume of the cone rounded  to the nearest whole number is:

 [tex]V_{(cone)}=\frac{1}{3}(3.14)(1.5\ cm)^2(7\ cm)\\\\V_{(cone})=16\ cm^3[/tex]

Answer:

Harold typed 76, Rebecca typed 62  

Step-by-step explanation:

It's Easy. For the first one, convert 1/5 and 2/3 to the like denominator of 15.  

Therefore, you have 3/15 and 10/15. Add these to get 13/15. Now, find 13/15 of 60. To do this you will have to multiply 13 and 15 by 4 to get 52/60. Since the question asks you for how many are left, you subtract 52 from 60 to get 8.  

And For the second one, first subtract 14 from 138. You have 124. Divide 124 by 2 to get 62. Then add 14 to Harold's total pages to get 76. 62 +76 = 138.

[tex]\displaystyle\\\lim_{x\to 2}\dfrac{x^2+2x-3}{x-3}=\dfrac{2^2+2\cdot2-3}{2-3}=\dfrac{5}{-1}=-5[/tex]

The right-hand limit of the function f(x) = (x^2 + 2x - 3)/(x - 3) as x approaches 2 is -5 after substitution of x = 2 into the function.

The question asks about the right-hand limit of the function f(x) = (x^2 + 2x - 3)/(x - 3) as x approaches 2. The first step in finding this limit is to simplify the function, if possible. In this case, we can factor the numerator to obtain (x - 1)(x + 3). However, since we are looking for a limit as x approaches 2, the denominator x - 3 will not be zero, and the expression does not need further simplification for this purpose. We then substitute x = 2 directly into the simplified function and find the limit.

So, the right-hand limit as x approaches 2 is simply f(2) = ((2)^2 + 2*2 - 3)/(2 - 3) = (4 + 4 - 3)/(-1) = 5/(-1) = -5.

Answer:

see explanation

Step-by-step explanation:

One way to divide is to use the denominator as a factor in the numerator

Consider the numerator

x(x - 9) + 9x - 5x + 7

= x(x - 9) + 4x - 7

= x(x - 9) + 4(x - 9) + 36 + 7

= x(x - 9) + 4(x - 9) + 43

quotient = x + 4, remainder = 43

Hence

[tex]\frac{x^2-5x+7}{x-9}[/tex] = x + 4 + [tex]\frac{43}{x-9}[/tex]

238(56)+238(34)+162(90)

=238(56+34) + 162(90)

=238(90) + 162(90)

=90(238+162)

=90(400)

=36000

For this case we must resolve the following expression:

[tex]238 (56) +238 (34) +162 (90) =[/tex]

We multiply term by term:

[tex]13328 + 8092 + 14580 =[/tex]

We add the terms:

[tex]13328 + 8092 + 14580 = 36000[/tex]

Answer:

(-7, 2).

Step-by-step explanation:

x + 12y = 17

x - y = -9

Subtracting:

0 + 13y = 26

y = 2.

Substitute for y in the second equation:

x - 2 = -9

x = -7.

Answer:

{-7,2}

Step-by-step explanation:

Given

x+12y=17     Eqn 1

x-y=-9          Eqn 2

We will use the substitution method to solve the system of equations. So, from eqn 2:

[tex]x-y=-9\\x=y-9[/tex]

Putting the value of x in equation 1:

[tex](y-9)+12y=17\\y-9+12y=17\\y+12y-9=17\\13y=17+9\\13y=26\\\frac{13y}{13}=\frac{26}{13}\\ y=2[/tex]

Putting the value of y in eqn 2:

[tex]x-2=-9\\x=-9+2\\x=-7\\So,\\Solution set = \{-7,2\}[/tex]

Answer:

y = -5

Step-by-step explanation:

To find the slope , we use

m = (y2-y1)/(x2-x1)

3/2 = (-2-y)/(2-0)

3/2 = (-2-y)/2

Since the denominators are the same, the numerators have to be the same

3 = -2-y

Add 2 to each side

3+2 = -2-y+2

5 = -y

Divide each side by -1

5/-1 = -y/-1

-5 = y

Answer:

the solution of linear equation 4b + 6 = 2 - 6 + 4 is b = -2

Step-by-step explanation:

We need to solve the linear equation

4b + 6 = 2 - 6 +4

Adding constants

4b + 6 = 0

Adding -6 on both sides

4b + 6 -6 = 0 -6

4b = -6

Dividing with 4 on both sides

4b/4 = -6/4

b = -2

So, the solution of linear equation 4b + 6 = 2 - 6 + 4 is b = -2

Step-by-step explanation:

3 * 4 = 12.

12 = 1 dozen

So you have to multiply 2.90 * 3

The answer is 8.70

=======================

That's one way to do the problem. Here's another.

4 muffins = $2.90

12 muffins = x                Cross multiply.

4x = 12*2.90

4x = 34.80                     Divide by 4

4x/4 = 34.80/4              Do the division

x = $8.70
