In one minute adrians fan oscillates 12 times if the fan is on for 8 minutes how many time will it oscillate

Answer:

27000 J

Step-by-step explanation:

The specific heat equation is: Q = mC∆T

Q is the energy in Joules.

m is the mass in grams of the substance.

C is the specific heat capacity.

∆T is the change in temperature.

Let's plug in what we know.

Q = 3000(0.9)(10)

Q = 27000 J

Hope this helps!

Answer:

Option E

Step-by-step explanation:

Explicit formula of a geometric sequence is,

[tex]T_n=a_1(r)^{n-1}[/tex]

Here, [tex]a_1=[/tex] First term

[tex]r=[/tex] common ratio

[tex]n=[/tex] number of terms

If, [tex]a_1=18[/tex] and [tex]a_2=9[/tex]

Common ratio of the sequence [tex]r=\frac{a_2}{a_1}[/tex]

[tex]r=\frac{9}{18}[/tex]

[tex]r=\frac{1}{2}[/tex]

By substituting these values in the formula,

[tex]T_n=18(\frac{1}{2} )^{n-1}[/tex]

Therefore, Option E is the answer.

Answer:

2/15

Step-by-step explanation:

4/10 * 3/9 = 12/90 = 2/15

Answer:

89°

Step-by-step explanation:

Total inner degree of PQRS = (4-2)*180° = 360°

PST is a straight line : 180°

angle PSR = 180-128

=52°

angle RQP + angle QPS = 360 - 52 - 130 = 178°

Angle PQR = Angle QPS

Angle QPS = 178/2 = 89°

Step-by-step explanation:

Answer: jacob is right

Step-by-step explanation:

each face in a cube is equal, and we know that there are six sides on a cube

this means that we need to find the surface area of one side and multiply it by six to see if jacob is correct

to find the area of one side you would do

a = Lw

a = 10 * 10

a = 100

so one face equals 100 cm^2 so 100 * 6 = 600

600 is less than 1000 so jacob is correct

Answer:

(x,y)↦ ( x + 1 ) , ( y + 9 )

scale factor 2  

Step-by-step explanation:

Step 1 identify the translation.

To do this we find the center of ⨀T and the center of ⨀T' and find the difference between their x and y values.

The center of ⨀T is at ( -1 , -7 )

The center of ⨀T' is at ( 0 , 2 )

we now find the difference between the x and y values. ( note that you must subtract the x and y values from the preimage from the translated image to get the correct translation. )

For the x values: 0 - ( - 1 ) = + 1

For the y values:  2 - ( -7 ) = + 9

So translation was (x,y)↦ ( x + 1 ) , ( y + 9 )

step 2 Find the scale factor

We can identify the scale factor by dividing the radius of the preimage by the radius of the dilated image.

The radius can be identified by finding the distance between the center and any point on the circle

The radius of the preimage is 3

The radius of the dilated image is 6

So scale factor = 6 / 3 or 2

Answer:35 51 98

Step-by-step explanation:

Answer:

Hello! Thanks for posting the question again!

Anyways here are the answers...

d = 35 because its a vertical angle

e = 51 because its a vertical angle

Now to find f we have to add these up then subtract by 360 then ÷ by 2 so 51 + 51 + 35 + 35 = 172 360 - 172 = 188 188 ÷ 2 = 94 so f = 94

Answer:

High

Step-by-step explanation:

Lets look at the chart, and see how similar each value is:

At 11, there is:

Both have 1 point. THis is similar

At 12:

Both have 1 point. This is similar

At 13:

One has 1 point, the other has 2 points. This is not similar

Next we have 14:

Both have 2 points. This is similar

15:

Both have 4 points. THis is similar

16:

Both have 3 points. This is similar

17:

One has 2 points the other has 1 point. This is not similar

So,  5 out of the 7 poitns are similar

And remember, the two points that are not similar are only off by 1.

So I would conclude that they are highly similar.

Hope this helps!

Answer:

45

Step-by-step explanation:

60/4 = 15

15 x 3 = 45

Answer:

45 dogs

Step-by-step explanation:

to figure this out we divide the ratio of total cats the the simplified ratio

(60 divided by 4 = 15)

to find out the dogs, multiply that base number, 15, into 3

(3 x 15 = 45)

the new ratio would be 60:45

Answer:

The size of the sample 'n' = 2401

Step-by-step explanation:

Step:1

Given that the margin of error = 2 % = 0.02

The margin of error is determined by

              [tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]

we know that the proportion

               [tex]\sqrt{p(1-p)} < \frac{1}{2}[/tex]

Step:2

The margin of error is determined by

              [tex]0.02 = \frac{1.96( \frac{1}{2} ) }{\sqrt{n} }[/tex]

              [tex]\sqrt{n} = \frac{1.96}{2 X 0.02}[/tex]

              √n  = 49

Squaring on both sides, we get

                n = 49 × 49

                n = 2401

Final answer:-

The size of the sample 'n' = 2401

Hey love! <3

Answer:

Your answer is 306 units^2!

Step-by-step explanation:

Let's work this out together!

First let's find the top and bottom square's area.

6 x 15 = 90

Since there are not only two of those shapes but THREE, 90 x 3= 270.

So 270 is the surface area of the middle rectangles.

Step 2! Let's find the area of these triangles. We know that both of the triangles are 6 on each side.

Think back to geometry formulas. The formula for finding the area of a triangle is different then a square.

Triangle formula: Base x Height / 2 = A

Rectangle formula: Base x Height = A

So 6 x 6 is 36, now we have to divide it by two; which equals 18.

Since there are TWO triangles, we multiply 18 by two giving us the total surface area of the triangles, 36.

Now let's add our products together!

36 + 270 = 306

Thus the total surface area being 306 units^2

Answer:

180 units^3

Step-by-step explanation:

Formula for the volume of a right triangular prism: V=1/3Ah (A=Area of base triangle, h=height)

BASE TRIANGLE

A= 1/2bh (base•height)

A= 1/2•10•4

A= 40 units^2

VOLUME OF PRISM

V=1/3Ah

V= 1/3•40•18

V= 180 units cubed

Answer:

C. –x + 8y = 56

Step-by-step explanation:

Write in standard form.

x  −  8 y  =  − 56

This is a linear function in the slope - intercept form:

y = m x + b and we need a standard form:

a x + b y = c

y = 1/8 x + 7   / * 8 ( we will multiply both sides of equation by 8 )

8 y = x + 56

- x + 8 y = 56  / * ( - 1 )

x - 8 y = - 56

The equation is  y = 1/8x + 7

Standard form equation is Ax + By = C,  where A > = 0.

First eliminate the fractions by multiplying the equation by 8

8y = x + 56

Subtract x from each side

-x + 8y = 56

SInce x coeficient can't be negative multiply the equation by negative one.

x - 8y = -56
