Answer:

0.67 cm/s

Step-by-step explanation:

The area of a square is given by :

[tex]A=x^2[/tex] ....(1)

Where

x is the side of a square

[tex]\dfrac{dA}{dt}=12\ cm^2/s[/tex]

Differentiating equation (1) wrt t.

[tex]\dfrac{dA}{dt}=2x\times \dfrac{dx}{dt}[/tex]

When A = 81cm²​, the side of the square, x = 9 cm

Put all the values,

[tex]12=2\times 9\times \dfrac{dx}{dt}\\\\\dfrac{dx}{dt}=\dfrac{2}{3}\\\\\dfrac{dx}{dt}=0.67\ cm/s[/tex]

So, the length of the side of a square is changing at the rate of 0.67 cm/s.

Answer:

The final answer is 78 inches, though I would recommend for you to read through the steps of how this is achieved.

Step-by-step explanation:

To start, to grasp the corresponding sides deal, think of it as saying Quad 1234 is equal to Quad ABCD. Now, it is fairly easy to make up the sides between the two shapes. With this, the following is true:

Side 12 ≅ Side AB

Side 23 ≅ Side BC

Side 34 ≅ Side CD

With the end, it loops back around to meet back at the first edge of the shape again, if you're looking for a side length.

Side 41 ≅ Side DA

Now, with the real stuff. We're greeted with the Quads DEFG and KLMN, and asked to find FG. Looking at it, FG would be using the 3rd and 4th letters of the set of quad edges. Comparing this to the other quad shape, the 3rd and 4th letters are MN. Therefore, lets use this.

Next, set these equal to each other. FG is 5y+3 and MN is 7y-27

5y+3 = 7y-27

5y = 7y-30

-2y = -30

2y = 30

y = 15

y equals 15.

Lastly, plug this into the equation for FG to get the final answer.

5(15)+3

75+3

78 inches

Answer:

-2

Step-by-step explanation:

going from 3 to -9 is taking away 12, so -12.

going from -4 to 2 is adding 6, so 6.

-12/6 simplifies to -2/1, or -2

Step-by-step explanation:

the chair can go in any time AFTER the bed, so let’s think bed first

then he wants to move the heavy stuff, then awkward.

so the dresser and desk are heavy, and the couch is awkward.

but the chair can go in at any time so E would make sense

Answer:

[tex]\frac{8}{9}[/tex]

Step-by-step explanation:

Since there are 432 tickets total and Gabriela bought 48, the chances of Gabriela not winning the grand prize is equal to the chance of any of the tickets she did not buy getting drawn. If she bought 48, then she did not buy 432-48=384 tickets. The chances of any of these being drawn is:

[tex]\frac{384}{432}=\boxed{\frac{8}{9}}[/tex]

Given:

Measure of arc CG is 125 degrees.

The measure of angle CDG is 85 degrees.

To find:

The measure of arc EF.

Solution:

Intersecting chords theorem: If two chords intersect each other inside the circle, then the measure of angle on the intersection is half of the sum of intercepted arcs.

Using the intersecting chords theorem, we get

[tex]m\angle CDG=\dfrac{1}{2}(m(arcCG)+m(arcEF))[/tex]

Let x degrees be the measure of arc EF.

Substituting the given values, we get

[tex]85^\circ=\dfrac{1}{2}(125^\circ+x)[/tex]

[tex]2\times 85^\circ=125^\circ+x[/tex]

[tex]170^\circ -125^\circ=x[/tex]

[tex]45^\circ=x[/tex]

Therefore, the measure of arc EF is [tex]45^\circ[/tex].

Answer:

60 miles per hour

Step-by-step explanation:

240/4 = 60 miles per hour

Answer:

60 miles per hour

Step-by-step explanation:

In order to find the rate at which Marcia's family's' car is travelling, you would simply divide the total miles, which would be 240 or "d," by the time, which would be 4 hours or "t."

So, Marcia's family's car is travelling at 60 miles per hour.

Answer:

Answer: 45 DVDs

Step-by-step explanation:

Assume that the number of DVDs owned by Manuel is x.

In comparison to Manuel therefore, the DVDs owned by Hakeem can be expressed as:

= 3/5 * x - 7

We know that Hakeem owns 20 DVDs so we can use this number to solve for x:

20 = 3/5x - 7

3/5x = 20 + 7

3/5x = 27

x = 27 ÷ 3/5

x = 27 * 5/3

x = 45 DVDs

Answer:

Slope = -7/8

Y-intercept = (0, 1)

Step-by-step explanation:

Answer:

[tex]slope = - \frac{7}{8} [/tex]

y- intercept= 1

Step-by-step explanation:

Rearrange the equation such that it is in the form of y=mx+c. This form is known as the slope-intercept form, and m is the gradient while c is the y-intercept.

7x +8y= 8

8y= -7x +8

Divide by 8 on both sides:

[tex]y = - \frac{7}{8} x + 1[/tex]

Thus, the slope is [tex] - \frac{7}{8} [/tex] and the y-intercept is 1.

Another way to find the y-intercept is to substitute x= 0 into the equation since the y-intercept occurs at x= 0.

7x +8y= 8

When x= 0,

7(0) +8y= 8

8y= 8

y= 8 ÷8

y= 1

Thus, the y-intercept occurs at y= 1 or the coordinate (0, 1).

Note: slope and gradient have the same meaning and can be used interchangeably

Hi there!

[tex]200\text{in}^3[/tex]

The formula for volume of a rectangular prism is:

[tex]V = LWH\\\\L-\text{Length}\\W-\text{Width}\\H-\text{Height}[/tex]

Our given measurements are:

[tex]\text{The height of 8 inches.}\\\\\text{The length of 5 inches.}\\\\\text{The width of 5 inches.}[/tex]

Plugging in the values into the formula...

[tex]V = 5 * 5 * 8\\\\\text{Multiply from left to right.}\\\\\rightarrow V=25*8\\\\\rightarrow \boxed{V=200}[/tex]

[tex]\text{The volume of the prism given should be }\boxed{\text{200 cubic inches.}}[/tex]

Hope this helps you. I apologize if it’s incorrect.  

Answer:

[tex]\angle BPC=100^{\circ}[/tex]

Step-by-step explanation:

Assuming P is the center of the circle:

The angle BPC encompasses arc BC. Notice angle CEB also encompasses this arc and the measure of angle CEB is given as [tex]50^{\circ}[/tex]. The measure of an angle with a point on the circle that encompasses an arc is equal to half of the measure of an angle with a point on the center of circle. Therefore, the measure of arc BPC is equal to [tex]2\cdot50^{\circ}=\boxed{100^{\circ}}[/tex]

Answer:

B) At alpha = 0.01, there is insufficient evidence to conclude the true mean wind speed at the site exceeds 25 mph.

Step-by-step explanation:

P-value of the test:

The p-value of the test is the probability of finding a sample mean above 25.

We are using the t-distribution, with test statistic t = 1.25 and 43 - 1 = 42 degrees of freedom. This probability is a right-tailed test.

With the help of a calculator, this p-value is of 0.1091.

Since the p-value of the test is 0.1091 > 0.01, at [tex]\alpha = 0.01[/tex] there is insufficient evidence to conclude the true mean wind speed at the site exceeds 25 mph, and the correct answer is given by option B.
