Which is an equation of a direct proportion?

Answer:

1 1/4

Step-by-step explanation:

For 12 dozen cookies, 5/6 cups of better are needed.

We have a oatmeal cookie recipe that calls for 1/2 cup of butter to make 5 dozen cookies. Wyatt needs to make 12 dozen cookies for the bake sale.

1/2 cup butter is needed for 5 dozen cookies.

For 1 dozen cookies, (1/2)/5 = (1/10) cups of better are needed.

For 12 dozen cookies, 10/12 cups or 5/6 cups of better are needed.

Therefore, for 12 dozen cookies, 5/6 cups of better are needed.

Answer:

The value of  [tex]x = \frac{1}{6}[/tex]

The length of the rectangle   [tex]= \frac{3}{2}[/tex] cm

The width of the rectangle  = [tex]\frac{16}{3}[/tex] cm

Step-by-step explanation:

Step(i):-

Given that area of the rectangle = 8 cm²

Length of the rectangle (l) = 3x+1

width of the rectangle (w) = 2x+5

The area of the rectangle = length × width

Given that area of the rectangle = 8 cm²

Step(ii):-

Now

                   (3x+1) ( 2x+5)    = 8

       ⇒      3x(2x+5) +1(2x+5) =8

                    6 x² + 15x + 2x +5 =8

         ⇒     6 x² + 17x -3 =0

        ⇒      6 x² + 18x -x -3 =0

       ⇒   6 x ( x+3) -1(x+3) =0

       ⇒   6x -1 =0  and  x +3 =0

              [tex]6x = 1[/tex]  and   x =-3

             [tex]x = \frac{1}{6}[/tex]

The length of the rectangle

                               [tex]= 3 (\frac{1}{6} ) +1 \\= \frac{3}{2}[/tex]

The width of the rectangle

                            [tex]= 2 (\frac{1}{6} ) +5[/tex]

                            = [tex]\frac{16}{3}[/tex]

Answer:

m = 2, c = -8.

Step-by-step explanation:

The general form of a straight line equation is

y = mx + c    where m = the slope and c is the y-intercept.

We are given the line

y = 2x + 4

Comparing this with the general form we see that the slope of this line  = 2 and the y-intercept C is 4.

Now the given line y = mx + c is parallel to y = 2x + 4 which means that their slopes are the same so we conclude that m = 2.

Now we need to find the value of c which is the y intercept of y = mx + c.

Consider the points A and B:

A is the point where the line y = 2x + 4 intersects the x axis so y = 0 at this point , So substituting in the equation:

0 = 2x + 4

-4 = 2x

x = -2.

So the point A is (-2, 0)

B  is the point where y = 2x + c cuts the x axis so here y = 0:

0 = 2x + c

2x = -c

x = -c/2.

Now we are given that the 2 intercepts are 6 units apart, so:

-c/2 - (-2) = 6

-c/2 + 2 = 6

-c/2 = 4

-c = 8

c = -8.

Answer:

Less than 90 degrees

Step-by-step explanation:If it were equal to 90 degrees it could make a perfect square as the angle and if its more it would be open wide i guess im a bad explainer sorry

Hence , Option B is correct. It is less than 90 degrees.

A figure which is formed by two rays or lines that shares a common endpoint is called an angle.

Observe the given figure.  A perfect Right Angle is in the  shape  "L"(or opposite/mirror L also). One can measure or construct it using a protractor.

If the L seems to be bent inwards , then its an acute angle and if the L is bent outwards, then it is an obtuse angle.  

From the given figure it can be concluded that the angle formed is an acute angle and hence its is less than 90 degrees.

Step-by-step explanation:

12 miles divided by 2 miles = 6

24 * 6 - 144

So the final answer is 144.

Answer: 144 minutes

Step-by-step explanation:

If she can run 2 miles in 24 minutes and she needs to run 12 miles you need to multiple 24 and 6 ( You get a six because 24 minutes is for TWO miles. So you need to split the 12 in half.)

Answer:

T(100) represents that the plane flies against the wind at 110mph for 0.714 hours

Step-by-step explanation:

Given

[tex]w = headwind[/tex]

[tex]T = time[/tex]

Model:

[tex]T(w) = \frac{300}{530 - W}[/tex] -- This was not properly presented in your question

Required

What does T(110) means

First, we calculate T(110):

Substitute 110 for w in [tex]T(w) = \frac{300}{530 - W}[/tex]

The expression becomes

[tex]T(110) = \frac{300}{530 - 110}[/tex]

[tex]T(110) = \frac{300}{420}[/tex]

[tex]T(110) = 0.714[/tex] -- approximated

T(100) represents that the plane flies against the wind at 110mph for 0.714 hours
