binders and four notebooks, the bill will be $4.85. If they buy three binders and
ten notebooks, the bill will be $8.75. What is the cost of each binder and
notebook?

Answer:

  15.08 m

Step-by-step explanation:

You can take the appropriate fraction of the whole circumference, or you can use the arc-length formula. You get the same answer either way.

Angle XZW is 180° -108° = 72°

The circumference is C=πd, so the arc of interest is ...

  XW = C(72°/360°) = πd/5 =π(24 m)/5 = 4.8π m

  XW ≈ 15.08 m

_____

If you use π = 3.14, then your answer will be 15.07 m.

Answer:

471.25

Step-by-step explanation:

A volume of a box is equal to length x width x height (abbreviated lwh). The given was: 14 & 1/2 inches long, 5 inches high, and 6 1/2 inches wide. So, all you have to do is multiply the given (I know it sounds too easy, but that's it):

14.5 * 5 * 6.5 = 471.25

So, the volume of the box is 471.25 inches cubed.

I hope that this helped & good luck!

Answer: y=12 x =9

Step-by-step explanation:

In a parallelogram the diagonals bisect each other making them equal.

this means 2y + 6 = 30

we can rearrange this as 30 - 6 = 2y

24 = 2y  therefore y = 12

3x - 3 = 24

We can rearrange this as 24 + 3 = 3x

3x = 27

27 / 3 = 9

x = 9

The equation of the parabola that represents the given graph is y = 3x².

The correct option is B.

A plane curve produced by a moving point such that its separation from a fixed point equals that of a fixed line is a parabola.

If the vertex of the parabola is at (0, 0), then the equation of the parabola has the form:

y = a x²

where "a" is a constant that determines the shape of the parabola. We need to find the value of "a" using the fact that the parabola passes through the point (1, 3).

Plugging in the coordinates of the passing point (1, 3), we get:

3 = a (1)²

3 = a

Therefore, the value of "a" is 5.

Hence, the equation of the parabola is:

y = 3x²

The coordinates of M is M’(4,-3).

Rotation means the circular movement of an object around a center. It is possible to rotate different shapes by an angle around the center point.

Given:

LMNP is rotated 90° clockwise around the origin.

If we rotate the figure in LMNP  about 90 degrees then the coordinates will change into

(x, y)  to (y, -x).

As, x= 3, y=4

The value of C is 3

Step-by-step explanation:

all of the angles of a triangle add up to 180°. first you would add 92 and 46 and get 138. You then subtract 180 and 138 and get 42. then you divide 42 by 14 and get 3. then substitute 3 back into the equation and you get 180.

Answer:

8[tex]x^{2}[/tex] + 3 + -6x

Step-by-step explanation:

First we need to find the like terms so that we could add them. In this case the like terms are,

1. 6x , -2x , -10x

So, these are the only terms that we can add in this expression.

Hence,

=> 8[tex]x^{2}[/tex] + 3 + (6x - 2x - 10x)

=> 8[tex]x^{2}[/tex] + 3 + -6x

And this is as simple as this expression can go until we find the value of "x" which is not yet told.

Answer:

Step-by-step explanation:

-40x + 8y = -24

 3x  -  8y = 24

-37x = 0

x = 0

0 + y = -3

y = -3

(0, -3)

Answer:

I will show you how to solve for x and y.

Step-by-step explanation:

-5x + y = -3

3x - 8y = 24

You can isolate y in the first equation, and substitute that into the second equation.

so to isolate y in -5x + y = -3, you would add 5x to both sides

this gives you y = 5x - 3

Then substitute this y into the equation below.

3x - 8(5x-3) = 24     (this way, the y variable disappears)

then distribute the 8 into the bracket

3x - 40x + 24 = 24

combine the variables

-37x + 24 = 24

isolate x by moving the constants to one side

-37x = 0

so x = 0

I am not sure if you want the rest, but here it is.

substitute x = 0 into one of the equations.

-5x + y = -3

-5(0) + y = -3

y = -3

Answer:

[tex] \sf \: 3a + 5[/tex]

Let's simplify the expression,

→ -4a + 14 + 7a - 9

→ (-4a + 7a) + (14 - 9)

→ (3a) + (5)

→ 3a + 5

Hence, the answer is 3a + 5.

Temperature increased each hour = [tex]\dfrac12[/tex] degrees Fahrenheit

Temperature increase in 6 hours = [tex]6\times\dfrac12=3\text{ degrees Fahrenheit}[/tex]

Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours
