Answer:

1  3/5 bags left

Step-by-step explanation:

If she gives 2/5 away, she keeps 3/5

3/5  *  2 2/3 = 3/5 * 8/3 =   24/15  = 1 9/15  = 1 3/5 bags left

its the one on the right :) x goes up 5 each time, y goes up 3 each time ; no jumps

Remark

If you find out the cost of 1 oz of each of them, that will determine the best buy. The smallest number is the best buy.

Givens

7 oz cost $2.38

15 oz cost $5.25

26 oz cost $8.58

Solution

7 oz cost $2.38

1 oz cost  x                  This is a proportion. 3 quatities are known. Find x Cross multiply.

7/1 = 2.38/x

7x = 2.38

x = $0.34 dollars

15 oz cost 5.25

1 oz costs x

15.1/1 = 5,25 x              Cross Multiply

15x = 5.25 * 1               Divide by 15                                

x = 5.25 / 15

x = $0.35

26 oz cost 8.58

1 oz   cost x

26/1 = 8.38/x                 Cross Multiply

26x  = 8.38                    Divide by 26

x = 8.38/20

x = 0.32 dollars

Answer

7 oz cost  0.34

15 oz cost 0.35

26 oz cost 0.32

Answer:

  7 boxes

Step-by-step explanation:

The area of a rectangular prism is given by the formula ...

  A = 2(LW +H(L+W))

The amount of wallpaper Carmen needs for one box is found by computing the area of the box.

__

  A = 2(5·6 +7(5+6)) = 2(30 +7·11) = 2(107) = 214 . . . square feet

  Carmen will be using a total of 214x square feet of wallpaper to cover x boxes. She has 1498 ft² available, so can cover ...

  1498 ft²/(214 ft²/box) = 7 boxes

Carmen has enough wallpaper to cover 7 storage boxes.

Answer:

60 small and 140 large = 60 + 280 = 340 this is correct!

Step-by-step explanation:

I guess we just use the process of eleimation.

50 small and 150 Large = 50+300 = 350 so that's not right.

130 small and 70 large = 130 + 140 = 270 so, that's not right.

120 small and 80 large = 120 + 160 = 280 so, that's not right.

60 small and 140 large = 60 + 280 = 340 this is correct!

First integral:

Parameterize -C (the reverse of C) by [tex]z = e^{it}[/tex] where [tex]0\le t \le\frac\pi2[/tex]. Then the contour integral is

[tex]\displaystyle \int_{-C} (z^2 - z + 2) \, dz = \int_0^{\frac\pi2} \left(e^{2it} - e^{it} + 2\right) i e^{it} \, dt[/tex]

[tex]\displaystyle = i \int_0^{\frac\pi2} \left(e^{3it} - e^{2it} + 2e^{it}\left) \, dt[/tex]

[tex]\displaystyle = i \left(\frac1{3i} e^{3it} - \frac1{2i} e^{2it} + \frac2i e^{it}\right) \bigg|_0^{\frac\pi2}[/tex]

[tex]\displaystyle = \left(\frac13 e^{3it} - \frac12 e^{2it} + 2 e^{it}\right) \bigg|_0^{\frac\pi2}[/tex]

[tex]\displaystyle = -\frac43 + \frac53i[/tex]

Then

[tex]\displaystyle \int_C (z^2-z+2) \, dz = -\int_{-C} (z^2+z-2) \, dz = \boxed{\frac43 - \frac53i}[/tex]

Second integral:

The integrand has a pole of order 2 at z = 3i which is contained in C. By the residue theorem,

[tex]\displaystyle \int_C \frac{z^2+z}{(z-3i)^2} \, dz = 2\pi i\, \mathrm{Res}\left(\frac{z^2+z}{(z-3i)^2}, z=3i\right)[/tex]

Compute the residue:

[tex]\displaystyle \mathrm{Res}\left(\frac{z^2+z}{(z-3i)^2},z=3i\right) = \lim_{z\to3i} \frac{d}{dz}\left[z^2+z\right] = \lim_{z\to3i} (2z+1) = 1 + 6i[/tex]

Then the value of the integral is

[tex]\displaystyle \int_C \frac{z^2+z}{(z-3i)^2} \, dz = 2\pi i (1 + 6i) = \boxed{-12\pi + 2\pi i}[/tex]

7  in    <==== no sqrt in the answer

Step-by-step explanation:

  = 7 (2)/2 = 7

For the function to be an odd function, then f(-x) = -f(x) and the function f(x) is not an odd function

The function f(x) is given as:

f(x) = x^2

For the function to be an odd function, then the following must be true:

f(-x) = -f(x)

So, we have:

f(-x) = (-x)^2 = x^2

-f(x) = -x^2

From the above computation, we can see that the functions f(-x) and -f(x) are not equal

Hence, the function f(x) is not an odd function

Answer:

22.5 km

Step-by-step explanation:

Since 1 cm on the map is 250000 cm in real life :

We can convert 250000 cm to km :

First we convert to m :

250000 ÷ 100  = 2500 m

Now we convert m into km :

2500 ÷ 1000 = 2.5 km

Now we multiply 2.5 km by 9 cm to get :

2.5 × 9  = 22.5 km

Therefore the 2 villages are 22.5 km apart.

Answer:

2.25 million km

Step-by-step explanation:

Step 1. Write ratio with "x"

Step 2. Create a proportion

Step 3. Cross multiply

Step 4. Solve for "x"

1 : 250,000

9 cm : x km

1/250,000 = 9/x

x = (9)(250,000)

x = 2.25 million km

Answer:

  48.8 lbs

Step-by-step explanation:

The forces can be modeled by a triangle with acute angles 20° and 26°, and obtuse angle 134° opposite a side of length 80. The larger component force will be opposite the angle 26°, and can be found using the Law of Sines:

  a/sin(A) = c/sin(C)

  x/sin(26°) = 80/sin(134°)

  x = 80sin(26°)/sin(134°) ≈ 48.753 . . . . pounds

The larger component force is about 48.8 pounds.
