draw circuit diagram to show that copper is a good conductor of electricity.
please answer quickly..

Answer:

A. The expression of "40 times the sum of 24 and 36" would be 40 x (24+36), and the value would be 2400.

B. for the words portion it would be "20 times the sum of 650 and 350", and the value of that expression is 20,000.

C. The expression of "divide the difference between 1,600 and 400 by 4" should be 1200 / 4, and if that is the correct way to format the expression then the value would be 300.

D. for the words portion it would be "100 times the sum of 78 and 12", and the value of that expression is 10,000.

Step-by-step explanation:

Answer:

40 times the sum of 24 and 36

40 × (24 + 36)

2400

20 times the sum of 650 and 350

20000

divide the difference between 1600 and 400 by 4

(1600 - 400) ÷ 4

300

100 times the sum of 78 and 12

9000

Answer:

4

Step-by-step explanation:

2+2 = 4

Answer:

2

Step-by-step explanation:

x²+2xy+y²

Here x² has degree 2

2xy has degree also 2 because x has 1 degree and y has 1 degree so 1+1=2

y² has degree 2

So the highest degree of the expression is 2

Answer:

BC = 36

Step-by-step explanation:

If <X ≅ <A, and <Y ≅ B, therefore ∆XYZ is similar to ∆ABC.

Since ∆XYZ is similar to ∆ABC, it follows that the ration of their corresponding side lengths would be equal.

That is:

[tex] \frac{AB}{XY} = \frac{BC}{YZ} = \frac{AC}{XZ} [/tex]

AB = 15

XY = 5

YZ = 12

Thus:

[tex] \frac{AB}{XY} = \frac{BC}{YZ} [/tex]

Plug in the values

[tex] \frac{15}{5} = \frac{BC}{12} [/tex]

Multiply both sides by 12

[tex] \frac{15}{5}*12 = \frac{BC}{12}*12 [/tex]

[tex] \frac{15*12}{5} = BC [/tex]

[tex] 36 = BC [/tex]

The length of the segment BC is 36 and this can be determined by using similar triangle properties and the given data.

Given :

The following steps can be used in order to determine the length of the segment BC:

Step 1 - According to the given data, XY = 5 , YZ = 12 , and AB = 15. Also angle X congruent to angle A and angle Y congruent to angle B.

Step 2 - So, according to the given data, it can be concluded that both the triangles are similar.

Step 3 - From the above steps, it can be concluded that the corresponding sides ratios of the triangles are equal.

[tex]\rm \dfrac{AB}{XY}=\dfrac{BC}{YZ}=\dfrac{AC}{XZ}[/tex]

Step 4 - Now, substitute the values of YZ, XY, and AB in the above expression.

[tex]\rm \dfrac{15}{5}=\dfrac{BC}{12}[/tex]

Step 5 - Simplify the above expression.

BC = 36

Answer:

b = 40

Step-by-step explanation:

The first step you have to do is multiply 4 on each side to cancel out the 4 under -b, so you can get b by itself.

4 x -10 = -b  x 4        should get this       -40 = -b

              4

Now the final step is to divide -1 on each side to cancel out the negative by b, thus getting b by itself. Then once that is done you will see that your answer is b=40.  

-40 = -b         should get this     40=b or b=40

-1      -1

Answer:

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

Answer:

sides stay the same length and angles must be equal

d = 3

Step-by-step explanation:

Coordinate Plane

The image provided shows the four points given:

A=(2, 1), B=(5, 1), C=(7,2), D=(4,2).

It can be clearly seen the length of CD is just the difference of their x-coordinates:

CD = 7 - 4 = 3

We can also use the formula of the distance.

Given two points C(x,y) and D(w,z), the distance between them is:

[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]

[tex]d=\sqrt{(2-2)^2+(7-4)^2}[/tex]

[tex]d=\sqrt{0^2+3^2}[/tex]

[tex]d=\sqrt{9}[/tex]

d = 3

Answer:

-1,512,390

Step-by-step explanation:

Given

a1 = 15

[tex]a_i = a_{i-1} -7[/tex]

Let us generate the first three terms of the sequence

[tex]a_2 = a_{2-1}-7\\a_2 = a_1 - 7\\a_2 = 15-7\\a_2 = 8[/tex]

For [tex]a_3[/tex]

[tex]a_3 = a_{3-1}-7\\a_3 = a_2 - 7\\a_3 = 8-7\\a_3 = 1[/tex]

Hence the first three terms ae 15, 8, 1...

This sequence forms an arithmetic progression with;

first term a = 15

common difference d = 8 - 15 = - -8 = -7

n is the number of terms = 660 (since we are looking for the sum of the first 660 terms)

Using the formula;

[tex]S_n = \frac{n}{2}[2a + (n-1)d]\\[/tex]

Substitute the given values;

[tex]S_{660} = \frac{660}{2}[2(15) + (660-1)(-7)]\\S_{660} = 330[30 + (659)(-7)]\\S_{660} = 330[30 -4613]\\S_{660} = 330[-4583]\\S_{660} = -1,512,390[/tex]

Hence the sum of the first 660 terms of the sequence is  -1,512,390

Step-by-step explanation:

Answer:

Remember this conversion factor:

1 U.S. customary cup = 0.0625 U.S. gallons

Step 2:

Let's pretend that you are converting 100 cups to gallons. To do this, simply multiply the number of cups you have by 0.0625 like so:

100 cups x 0.0625 gallons/cup

Solution

100 cups x 0.0625 gallons/cup = 6.25 gallons

Answer:

You will get there in 4 hours

Step-by-step explanation:

Use the distance formula D=r•t , to determine how much time, t, in hours it will take you to get there

Where D = Distance

r = rate = Average Speed

t = time in hours

From the question

D = 220 miles

t = ??

r = 55 miles/hour

Hence:

220miles = 55miles/hour × t

t = 220/55

t = 4 hours

You will get there in 4 hours
