Step-by-step explanation:

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

_______

2r^3 - 12r

Step-by-step explanation:

Let's solve for a.

24 = a(−2r^1)(6 − r^2)

Step 1: Flip the equation.

2ar^3 − 12ar = 24

Step 2: Factor out variable a.

a(2r^3 − 12r) = 24

Step 3: Divide both sides by 2r^3 - 12r.

a(2r^3 − 12r)            24

__________ = ________

   2r^3 - 12r       2r^3 - 12r

Answer:

Waddup bro. For your answer, think of it this way. What 3 digits will make up 9? 1 x 9 is 9. So that would work. find it out by trying out different combination that would make up 9. I'm not gonna write all of 'em but 3 digits would add up to 9. There are no other groups of numbers adding up to 9. 4. Add up the remaining digits, 5 + 5 + 0 + 3 = 13. 5.13 is more than 9, so 1 + 3 = 4.  To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers. So add all up the singe digits and divide it by how much there is.

Step-by-step explanation: The other person accidentally put 49 instead of 42

The equations that are correct are n = 10, CF = 59 and FE = 42

From the attached diagram, we can see that the opposite side of the parallelogram are equal, hence;

DE = CF
6n - 1  = 5n + 9'

Find the value f n

6n - 5n = 9 + 1

n = 10

CF = 5n + 9

CF = 5(10) + 9
CF = 59

For the measure of FE
FE = 4n + 2

FE = 4(10) + 2

FE = 42

Hence the equations that are correct are n = 10, CF = 59 and FE = 42

The area of the model on the left is 12[tex]cm^{2}[/tex]

The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.

Scale Up (smaller to larger)         = [tex]\frac{Larger figure measurement }{Smaller figure measurement}[/tex]

Scale Down (larger to smaller)     = [tex]\frac{Smaller figure measurement }{larger figure measurement}[/tex]

According to question

area of right triangle which have (1cm= 2inch) is 108 [tex]cm^{2}[/tex] .

and Left triangle  have (1cm= 6inch)

we will convert cm into inch for right triangle

area of right triangle = 108 [tex]cm^{2}[/tex]

 as 1 cm = 2inch

1 [tex]cm^{2}[/tex] = 4 [tex]inch^{2}[/tex]

therefore,

108 [tex]cm^{2}[/tex] = 4 * 108  [tex]inch^{2}[/tex]

as mentioned that  two different models of the same triangular handkerchief

and left triangle is 1 cm = 6 inch

1 [tex]cm^{2}[/tex] = 36 [tex]inch^{2}[/tex]

now we have to scale down as we have to larger to smaller

Scale Down (larger to smaller)    = [tex]\frac{Smaller figure measurement }{larger figure measurement}[/tex]

= 4*108  / 36

= 12

Hence, the area of the model on the left is 12[tex]cm^{2}[/tex]

Here, we are required to determine what the y-intercept represents.

The equation of a line is given by;

y = mx + c.

where m = slope

and c = y-intercept.

Since the y-axis represents the Gallons of water left in the tank.

The y-intercept represents the point which corresponds to when x = 0.

In this case, the y-intercept represents the amount of water that is initially in the water barrel. i.e 45gallons of water.

Answer:

A). X is 80 degrees

Step-by-step explanation:

B). We know this because AD and EH are congruent.  Since B and F are also congruent, then x and the angle above B must be congruent. So, the angle an=bove B is 80 degress, which makes line AD 180 degrees, or a straight line. that must mean that x is 80 degrees as well.

Answer:

Step-by-step explanation:

y=x²+4x-7

=x²+4x+4-4-7

=(x+2)²-11

axis of symmetry is x=-2

vertex is (-2,-11)

x²+4x-7=0

[tex]x=\frac{-4 \pm\sqrt{4^2-4(1)(-7)} }{2(1)} \\=\frac{-4 \pm \sqrt{16+28} }{2} \\=\frac{-4 \pm 2\sqrt{11} }{2} \\=-2 \pm\sqrt{11}[/tex]

Answer:

Axis of symmetry is x = -2

(-2, -11) is the vertex

Roots are

-2 + [tex]\sqrt{11}[/tex], -2 - [tex]\sqrt{11}[/tex]

Step-by-step explanation:

a) Axis of symmetry equation is: x = -b/2a

Original equation: y = [tex]x^2+4x-7[/tex]

So...

x= -4/2(1) = -2

Axis of symmetry is x = -2

b) Vertex Point can be found by plugging into original equation.

[tex]y =x^2+4x-7[/tex]

=> y = [tex](-2)^2+4(-2)-7[/tex]

=> 4 - 8 - 7 = y

=> -11 = y

(-2, -11) is the vertex

c) quadratic formula is  [tex]x = \frac{-b +-\sqrt{b^2-4ac} }{2a}[/tex]

Lets plug in the values.

[tex]\frac{-4 +- \sqrt{4^{2}-4(1)(-7) } }{2(1)}[/tex]

[tex]\frac{-4 +- \sqrt{16+28 } }{2}[/tex]

[tex]\frac{-4 +- \sqrt{44 } }{2}[/tex]

[tex]\sqrt{44} = 2\sqrt{11}[/tex]

-4 +- 2[tex]\sqrt{11}[/tex]

--------------

     2

Here, i will factor out 2, and take out the +- and make it into two equations

2(-2 + [tex]\sqrt{11}[/tex]) / 2 = -2 + [tex]\sqrt{11}[/tex]

2(-2 - [tex]\sqrt{11}[/tex]) / 2  =   -2 - [tex]\sqrt{11}[/tex]

x= -2 + [tex]\sqrt{11}[/tex]

or

x = -2 - [tex]\sqrt{11}[/tex]

"R" is for the rate of interest (ex. 3.86%)

"T" is for the time passed.

As the area is 12, the length multiplied by the width must equal 12

Therefore, we can eliminate option B and option D as they wouldn't multiply to give 12

Let's test option A to see if it gives a perimeter of 16

2 + 6 + 2 + 6 = 16

As you see, this sums to 16

Thus, your answer is option A

√137.25=c²

11.72.... = c

The Radius of the circle is approximately 11.72cm

Step-by-step explanation:

Using this data. Create a Triangle with the Chord and Center of the dot. We know the distance between the chord and center which is one length of one of the sides.

We split the chord from the intersecting line from the center to the chord making the second line being 7.5cm

After We draw a line from the center of the circle to where the chord meets to the edge of the circle to create the triangle

We now have 2 measurements and can use Pythagorean Theorem to determine the radius from the missing length of the triangle.

Answer:

B. A (1, −2) → A ′(−4, −1) → A ″(−1, −1)

Step-by-step explanation:

When you see anything in between <> (let's say <a, b> are the numbers), it basically means <x+a, y+b>.

So if you replace a with -5, b with 1, and x and y with (1, -2) you get...

= (1 + (-5), -2 + 1)

= (1-5, -1)

= (-4, -1) ----------> Those are the coordinates of the new point.

But wait, it says that we now have to translate along the vector <3, 0>

So (-4, -2) become the new (x, y) coordinates and <3, 0> become the new a, b

= (-4+3, -1 + 0)

= (-1, -1)

That means that the coordinates of point A'' are (-1, -1)

Another way you could do this is by combining the two translations to just do one translation. It'll skip over the middle step, but will still give you the correct answer.

You would combine them by adding the translations of the x-coordinates together and the y-coordinates together

= <-5 + 3, 1 + 0 >

= <-2, 1>

Now you translate the point by this vector and...

= (1 - 2, -2 + 1)

= (-1, -1)

Tada! It works!

Therefore, the answer is B.

Answer: For Ryan to get an average of exactly 91, she needs to get a 90 on her fifth quiz.

Step-by-step explanation:

You can find the average of a set of numbers by adding them together and dividing the sum by the amount of numbers added.

Ryan has five total quizzes. Only four of them are known, so we can represent her fifth quiz as X.

[tex]\frac{87 + 93 + 96 + 89 + x}{5}[/tex], dividing the five quizzes' sum by 5

She wants the average to be exactly 91, so you can set the expression equal to 91 and solve:

[tex]\frac{365 + x}{5} = 91\\\\365 + x = 455\\\\x = 90[/tex]

For Ryan to get an average of exactly 91, she needs to get a 90 on her fifth quiz.
