A solid has a volume of 128 cubic units and a surface area of 160 square units. The solid is dilated, and the image has a volume of 54 cubic units.

What is the surface area of the image?

Answer:

  x = 125

Step-by-step explanation:

Given a heptagon with 60° and 90° angles marked, one marked 2x°, and the remaining angles marked x°, you want o know the value of x.

The sum of the interior angles of a heptagon is ...

  180° × (7 -2) = 900°

Using the given values, this tells us ...

  90° +x° +x° +x° +x° +60° +2x° = 900°

  6x = 750 . . . . . . . divide by °, subtract 150

  x = 125 . . . . . . divide by 6

The value of x is 125.

Hello,

I hope you and your family are doing well!

To calculate the amount of interest earned on a savings account, you can use the following formula:

interest = principal * rate * time

In this case, the principal is $9,500, the rate is 3.75%, and the time is 1 year. Plugging these values into the formula, we get:

interest = $9,500 * 3.75% * 1 year = $356.25

So, in a year, Alice would earn $356.25 in interest on her savings account.

You draw the line of the graph and every point on the line is a solution

Step-by-step explanation:

y = mx + b  You graph the b which is the y intercept.  This is where the graph crosses the x axis.  In this case it is -12.  From that point (0,-12)  You follow a pattern which is the slope.  In this case the slope is -3.  That mans that you move three units down and then 1 unit right.

Answer: Our answer set is( -1,-2 )

Step-by-step explanation:

y = x - 1

y = 3x + 1

We can use the combine method here.

==> - 1y + 1x = 1  (y = x - 1)

==>  -1y +3x = -1 (y = 3x + 1)

- 1y + 1x = 1  

 -1y +3x = -1

To single out any of the two variables, we need them to cancel out. Let us choose to cancel out y. We therefore multiply by negative 1 in the first re-arranged equation.

==> -1* (- 1y + 1x )= (1 ) * -1

Now we add the equations

==> 1y -1x = -1

==>-1y +3x = -1

______________

2x = -2

Divide.

==> x = -1

Now we insert x into any of the two original equations;

y = (-1) - 1

The value of x, y and z are 2/3, 1, and 3/2 if the system of equations 3⁢x+y+2⁢z=6 6⁢x−2⁢y=2 3⁢x+y−2⁢z=0

It is defined as the relation between three variables, if we plot the graph of the linear equation we will get a plane.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The linear equations are:

3⁢x+y+2⁢z=6

6⁢x−2⁢y=2

3⁢x+y−2⁢z=0

From equation (I) and (III)

6x + 2y = 6

From the above equation and equation (II)

12x = 8

x = 8/12 = 2/3

y = 1

z = 3/2

Thus, the value of x, y and z are 2/3, 1, and 3/2 if the system of equations 3⁢x+y+2⁢z=6 6⁢x−2⁢y=2 3⁢x+y−2⁢z=0

The line r has slope 6 and coordinates in the specified coordinate plane, based on the given dilation (0, 12)

Dilation:

Dilation is the scaling factor multiplied by the supplied line to line ratio.

Given

Line p in the coordinate plane has a y-intercept and a slope of 6. (0, 8). Line p is dilated by a factor of 4 with center to produce line r. (0, 4).

Here, we need to determine line r's slope and y-intercept.

Here, the scaling factor is known to be 4.

Consider the line r's slope, which won't change, and its intercept, which will be their ordinate added.

So, it can be written as,

=> Intercept = 8 + 4

=> Intercept = 12

y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

In the perpendicular lines the product of slopes will be -1

m1m2=-1

y=x+4 is the given line, it has slope of 1, so the perpendicular line will have slope -1.

The line is passing through (8,2)

2=-1(8)+b

2=-8+b

2+8=b

10=b

Hence, y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4

Answer:

Step-by-step explanation:

Since the triangles are similar, we know the ratio of the sides is a constant. We know that SQ is 55, and the corresponding side on the other triangle is 10. This lets us find the ratio for the whole triangle! The ratio is 55/10, or 5.5.

To solve for RS, consider the corresponding side on the other triangle(LS) which is 18. We multiply that by the ratio to get 18 * 5.5 = 99, which is the length of RS.

I don't know if you need to solve for x, but if you do, here it is! We have [tex]99 = 12x+3[/tex] (the equation for side RS). subtracting 3 from both sides results in [tex]96 = 12x[/tex], and dividing by x gives us that x = 8.

The scientific notation of the wavelength of green light in a spectrum

In scientific notations numbers are written in the form of a base that is

0  ≤ b < 10 and multiplied by 10ⁿ where n represents integers.

We write large standard numbers in scientific form in a compact manner.

Given, The wavelength of green light in a spectrum is about 0.000003 feet.

Now, the decimal is 6 places before so we have to move the decimal 6 places to the right, and to maintain the actual value we'll raise it to 10⁻⁶.

Therefore, 0.000003 feet,

Answer:

  (c)  12(2v-7)

Step-by-step explanation:

You want the expression resulting from factoring out the greatest common factor from the sum 24v -84.

The greatest common factor here is the GCF of 24 and 84. We note that ...

  24 = 12·2

  84 = 12·7

and 2 and 7 have no common factors. Then the GCF of 24 and 84 is 12.

The factored expression is ...

  24v -84 = 12(2v -7)

__

Additional comment

The GCF can also be found by considering the remainder from dividing 84 by 24. That remainder is 12, which divides both numbers with a remainder of 0. Hence 12 is the GCF.

If the remainder did not divide both numbers with a remainder of 0, then the process is repeated to find the GCF of the smaller number (24) and the remainder. (This is a description of Euclid's algorithm for finding the GCF.)

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time.

if x represents the the number of weeks for saving and y represents the equal saved amount, then

42+16x = y equation 1

-70+ 30x = y equation 2

subtract equation 1 from 2

-70-42+16x- 30x= 0

-112+14x= 0
