Answer:

each piece will be 3 1/4 inches

Step-by-step explanation:

22 3/4 can be rewritten as 91/4. to divide, you use keep, change, flip (keep the first fraction, change the sign, and flip the second fraction) . u will end up with 91/4 times 1/7, which is 91/28 or 3 1/4

Each piece of ribbon will be 3(1/4) inches.

Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.

[tex]22\dfrac{3}{4}[/tex]

This expression can be rewritten

[tex]\dfrac{88+3}{4} = \dfrac{91}{4}[/tex]

Since ribbon has to be divided into 7 equal pieces

[tex]\dfrac{\dfrac{91}{4}}{7}[/tex]

[tex]\dfrac{91}{4} \times\dfrac{1}{7}[/tex]

[tex]\dfrac{91}{28} = \dfrac{13}{4}[/tex]

Answer:

A. 60°

Step-by-step explanation:

There's a very straight-forward explanation for this, thank god! XD

For this type of problem, there's a rule to follow for the outside angle. X and 120 should equal 180, so all you need to do is fill that gap.

180-120 = 60

60 is your answer because it completes the whole angle.

Answer = 864cm squared

Answer:

You're correct, it's 7.5!

Step-by-step explanation:

15% is still 15/100. So, if you to divide 100 by 2 to convert it to 50, then you divide 15 by 2 as well! And the answer to that is 7.5.

Answer: 20

Step-by-step explanation:

Given, Sonya wrote each letter of LEDBETTER on a separate index card and put the cards in a box.

Total letters = 9

Number of times T appeared = 2

Thus, if we pick one card , the probability of getting card with T would be :-

[tex]\dfrac{\text{Number of times T appeared}}{\text{Total letters}}\\\\=\dfrac{2}{9}[/tex]

If she performed this experiment 90 times, then the best prediction for the number of times that Sonya would pick a T would be :

90 x ( probability of getting card with T)

[tex]=90\times\dfrac{2}{9}=10\times2=20[/tex]

Hence, the the best prediction for the number of times that Sonya would pick a T = 20.

Answer:

no, because in a function, the input is paired or has only one output, but here 20 is paired to both 40 and 42, which doesn't make it a function.

Answer:

A = x(x − 4) − 0.5(8)(x − 4) − 3(7)

Step-by-step explanation:

x = length, making the width (x-4)

The stage closet will be (x-4)(8)(1/2)

The rectangle is 7(3)

That makes the painted area x(x-4) - 4(x-4)

So...

A = x(x − 4) − 0.5(8)(x − 4) − 3(7)

The printed area of the theater room is x(x − 4) − 0.5(8)(x − 4) − 3(7). Then the correct option is D.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 11 feet.

The width of the floor is 4 feet less than the length.

It will have a stage and a closet, and the remaining area of the floor will be painted.

Let, the length be x

Then the width will be (x - 4)

Then the stage closest will be

[tex]\dfrac{8(x- 4)}{2} \Rightarrow 4(x-4)[/tex]

The rectangle is 7(3)

The painted area will be given as

[tex]\rm x(x-4) - 4 (x-4)[/tex]

Then we have

[tex]\rm area = x(x - 4)- 0.5(8)(x - 4) - 3(7)[/tex]

Answer:

-177,856 does not equal 15

-177,856=15

Answer:

see explanation

Step-by-step explanation:

To find the x- intercept, where the line crosses the x- axis, let y = 0 in the equation and solve for x, that is

11x + 6 = 0 ( subtract 6 from both sides )

11x = - 6 ( divide both sides by 11 )

x = - [tex]\frac{6}{11}[/tex] , thus coordinates of x- intercept are

( - [tex]\frac{6}{11}[/tex], 0 )

To find the y- intercept, where the line crosses the y- axis, let x = 0 in the equation and solve for y, that is

y = 11(0) + 6 = 0 + 6 = 6, thus coordinates of y- intercept are

(0, 6 )

Answer:

2037.75m/s

Step-by-step explanation:

To calculate the speed of a wave, you need to multiply the wavelength by the frequency. In this case, 627*3.25=2037.75m/s. Hope this helps!

The speed of a sound wave with a frequency of 627 hz and a wavelength of 3.25 m is calculated using the formula v = f λ, where v is the speed, f is the frequency, and λ is the wavelength. Multiplying the given frequency and wavelength gives a speed of 2037.75 m/s for the sound wave.

The speed of a sound wave is calculated by multiplying its frequency by its wavelength using the formula v = f λ, where v is the speed of the wave, f is the frequency, and λ (lambda) is the wavelength.

Given that the frequency of the sound wave is 627 hz and the wavelength is 3.25 m, we can substitute these values into the formula to find the speed:

v = 627 hz × 3.25 m

Now, let's perform the multiplication to solve for v:

v = 2037.75 m/s

Therefore, the speed of the sound wave is 2037.75 meters per second.

Final answer:

To calculate the number of square units of cardboard used to construct Stacey's cookie box, we need the box's dimensions to find the surface area. If the box were similar to a 9x9x4 inch doughnut box mentioned in the examples, the calculation would result in 306 square inches. Without the exact dimensions, we use the formula for surface area and round to the nearest tenth if necessary.

Explanation:

To determine how many square units of cardboard were used to construct Stacey's cookie box, we need to calculate the surface area of the box. However, the question does not provide the exact dimensions of the solid, so let's assume that we have the length, width, and height of the box. Then, the surface area of the box can be calculated as twice the sum of the length times width, length times height, and width times height (2(lw + lh + wh)).

As an example, if the box had dimensions of length (l), width (w), and height (h), and let's say that l=9 inches, w=9 inches, and h=4 inches, similar to the doughnut box mentioned in the provided information, the surface area would be:

Surface area = 2(lw + lh + wh) = 2(9*9 + 9*4 + 9*4) = 2(81 + 36 + 36) = 2*153 = 306 square inches

Now, if Stacey's cookie box has different dimensions, you would plug those values into the surface area formula instead. If the calculated surface area is not a whole number, the question advises to round to the nearest tenth.

try different values on the line! plug them in and you'll see that every x value is 3!

Answer:

x=3

Step-by-step explanation:

Because there is no slope (or the slope is undefined), there is another way to write the equation. Instead of y=mx+b, it will be either x=b or y=b, y=b being a horizontal line and x=b being vertical. To find b, simply find the value of x or y. The line has infinite points on it with one similarity, being their x value is 3. Hence, the equation is x=3.
