You are making a welding fixture and must cut down a length of copper tubbing from 15 1/8 inches to 8 3/4 inches. If the leftover piece is long enough , you will use it in another fixture . How long will the leftover piece be ?

Hey there! :)

Answer:

Length = 24 meters.

Width = 8 meters.

Step-by-step explanation:

Recall that to find the area of a rectangle, the formula is as shown:

A = l × w

In this case, the length is 3 times the length of the width, or 3 : 1.

Let w = width, and

3w = length.

Find the value of w by plugging in these values into the equation:

192 = 3w · w

192 = 3w²

Divide both sides by 3:

64 = w²

Square root both sides:

w = 8 meters. This is the width.

The length is equivalent to 3w, so:

3(8) = 24 meters.

Answer:

805

Step-by-step explanation:

Scaling up by a factor of ten means that you must multiply the original number by 10. Because 10 has one zero, the best way to figure this out is just moving the decimal to the right ONCE (just like there is ONE zero)! This gives us 805.

In general for a rectangle of dimensions w by h and a semicircle of diameter w we get an area:

A = wh + \frac 1 2 \pi (\frac w 2)^2

The halfs are because a semicircle is half a circle and a radius is half a diameter.

We're told

h = 1+ 3w

Substituting,

A(w) = w(1+3w) + \frac 1 2 \pi (\frac w 2)^2

Answer:

B.

Step-by-step explanation:

If you want to find a table with a proportional relationship, you are looking for one where the x-values and y-values increase at the same linear rate.

In Option A, the x-values increase steadily by 1 and then by 2, but the y-values jump around. The numbers are not proportional.

In Option B, every time an x-value is presented, the y-value is two times the value of x. So, this is a proportional relationship.

In Option C, it is true that for almost every time an x-value is presented, the y-value doubles the x-value, but when x is 0, y is 1. That is not a proportional relationship.

In Option D, it is the same thing as Option A.

So, your answer is Option B.

Step-by-step explanation:

Each time you roll a die, you have a [tex]\frac{1}{6}[/tex] chance of rolling a 3. It's even rarer to roll two 3s in a row, and to find a consecutive probability, we have to multiply the two probabilities. In this case, both probabilities are [tex]\frac{1}{6}[/tex].

Answer:

C. Both A & B

Step-by-step explanation:

Solve the equations given:

Equation A:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 11x and add 7 to both sides:

16x (-11x) - 7 (+7) = 11x (-11x) - 32 (+7)

16x - 11x = -32 + 7

Simplify. Combine like terms:

16x - 11x = -32 + 7

5x = -25

Isolate the variable, x. Divide 5 from both sides:

(5x)/5 = (-25)/5

x = -25/5

x = -5

Equation A is an answer choice.

Equation B:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 10 & subtract 2x from both sides:

-4x (-2x) - 10 (+10) = 2x (-2x) + 20 (+10)

-4x - 2x = 20 + 10

Simplify. Combine like terms:

-4x - 2x = 20 + 10

-6x = 30

Isolate the variable, x. Divide -6 from both sides:

(-6x)/-6 = (30)/-6

x = 30/-6

x = -5

Equation B is also an answer choice.

C. Both A & B is your answer.

Answer:

x= 3/2 = 1.5

Step-by-step explanation:

● 5(4x-10)+10x =4(2x-3)+2(x-4)

Simplify the products

● 5*4x-5*10+10x = 4*2x-4*3+2*x-2*4

● 20x-50+10x = 8x-12+2x-8

Add the terms that don't contain x with each other

●20x-50+10x = 8x-20+2x

Add 20 in both sides

●20x-50+20+10x = 8x-20+2x+20

●20x-30+10x = 8x+2x

Add together the terms that contain x

●30x -30 = 10x

Add -10x in both sides

●30x-30-10x = 10x-10x

● 20x -30 = 0

Add 30 in both sides

● 20x-30+30 = 30

● 20x = 30

Divide both sides by 20

●20x/20 = 30/20

● x= 30/20

● x= 3/2

● x= 1.5

the point on the plane (-15, 5)

Step-by-step explanation:

These lines are:

1)  a vertical line (x=-15) which implies that all x values of the points that it contains have coordinate x= -15

2) a horizontal line (y=5) which implies that all y values of the points that it contains have coordinate y = 5

Then the intersection must occur at x = -15 and y = 5, that is at the point (-15, 5)

Answer:

Multiplication property of equality

Step-by-step explanation:

Given

Step 4: b = -27/8

Required

Which property justifies it?

First, it should be noted that step 4 is a result of step 3

When step 3 is multiplied by 3/8 on both sides, we have step 4;

i.e.

[tex]\frac{8}{3b} = -9[/tex]

[tex]\frac{8}{3b} * \frac{3}{8} = -9 * \frac{3}{8}[/tex]

[tex]b = -9 * \frac{3}{8}[/tex]

[tex]b = \frac{-9 * 3}{8}[/tex]

[tex]b = \frac{-27}{8}[/tex]

The property that allows 3/8 be multiplied on both sides is referred to as the multiplication property of equality

Answer:

5 cm

Step-by-step explanation:

Area of 3 cm circle

A = pi r^2 = pi *3^2 = 9pi

Area of 4 cm circle

A = pi r^2 = pi *4^2 = 16pi

The area of the new circle is 16pi+9pi = 25 pi

25 pi = pi r^2

Divide each side by pi

25 = r^2

Take the square root of each side

sqrt(25) = sqrt(r^2)

5 = r

The radius is 5

Answer:

B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.

Step-by-step explanation:

$846 = $87 + $23M

The $846 represents the amount that he wants to save. $23M represents how much money he wants to deposit every M months. $87 represents the amount that he has already deposited (the constant).

And so, the correct answer will be B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.

Step-by-step explanation:

Use the formulas given and plug them in

Answer: 10.

Step-by-step explanation:

You are given the equation

(ax+b)(ax+c)=4x^2-25

Expand the Left hand side by opening the bracket.

a^2x^2 + axc + abx + bc

a^2x^2 + (axc + abx) + bc = 4x^2 + 0x - 25

From the equation above, we can see that;

a^2x^2 = 4x^2

a^2 = 4

a =  √4

a = 2

Also, axc + abx = 0x

axc = abx

ax will cancel out from both sides

c = b

From the equation, bc = 25

But c = b. Substitute c for b

b^2 = 25

b =  √25

b = 5 = c

b + c is therefore 5 + 5 = 10
