Answer: Length = 2x✓15

Step-by-step explanation:

A rectangle has a width of 2x inches and a diagonal length of 8x inches. We are told to find the length of the rectangle. The square of the diagonal is the addition of the square of the length and square of the width.

Adjacent² = length² + width²

(8x)² = length² + (2x²)

Length² = 64x² - 4x²

Length² = 60x²

Length = ✓60x²

Length = ✓4 × ✓15 × ✓x²

Length = 2 × ✓15 × x

Length = 2x✓15

Answer:

Height of cone is 5m

Step-by-step explanation:

Answer:

[tex]1.6[/tex]                                                                                 - written in [tex]2/12/2021[/tex]

Step-by-step explanation:

The answer is [tex]1.6[/tex] because, [tex]\frac{5+8+11+7+9}{5} = 8[/tex] and [tex]8-5=3[/tex], [tex]8-8=0[/tex], [tex]11-8=3[/tex], [tex]8-7=1[/tex], and [tex]9-8=1[/tex].

So use all the sums and you'll get this: [tex]\frac{3+0+3+1+1}{5} =1.6[/tex]

This is exactly how I got the answer, I also did it on khan because I didn't trust the other person above me, and I got the same answer as him. So I did this to prove he's correct.

Answer:[tex]\frac{1}{64}^{th}[/tex]

Step-by-step explanation:

Given

Suppose V is the original volume of cone having r as radius and h as height

If we multiply all the linear dimensions of ac one by [tex]\frac{1}{4}^{th}[/tex]

the [tex]r'=\frac{r}{4}[/tex]

[tex]h'=\frac{h}{4}[/tex]

Therefore new volume is

[tex]V'=\frac{1}{3}\pi r'^2h'[/tex]

[tex]V'=\frac{1}{3}\pi (\frac{r}{4})^2(\frac{h}{4})[/tex]

[tex]V'=\frac{1}{64}\times \frac{1}{3}\pi r^2h[/tex]

[tex]V'=\frac{V}{64}[/tex]

So new volume becomes [tex]\frac{1}{64}^{th}[/tex] of the original one

Step-by-step explanation:

Answer:

-7/-3

Step-by-step explanation:

The point (6,9) should be labeled as x1 and y1 and the point (0,-5) should be labeled as x2 and y2, so the slope equation ends up as -5-9 / 0-6, which turns out to be -14 / -6, but when you simplify it, it becomes -7 / -3. :)

The slope of line given below is 7/3.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have the points as (6, 9) and (0, -5)

So, the slope of line

slope = (-5 - 9)/ (0-6)

slope = -14 / (-6)

slope = 7/3

Thus, the required slope is 7/3.

Answer:

slope = -4

y-intercept = -10

Step-by-step explanation:

First, isolate the y. Note the equal sign, what you do to one side, you do to the other. Subtract 4x from both sides:

4x + y = -10

4x (-4x) + y = -10 (-4x)

y = -4x - 10

Note the slope intercept form: y = mx + b

y = y

m = slope = -4

x = x

b = y-intercept = -10

Answer:

slope m=-4

y intercepts (0,-10)

Answer:

20 Counters

Step-by-step explanation:

Total number of counter in a bag= 200 Counters

If 50 Counters out of the total have white paint, the value is then represented as

= 50/200

=1/4

The initial 50 Counters taken out is then put in the bag again and mixed thoroughly to get an even distribution.

If 80 Counters are taken out of the bag, the value is represented as

= 1/4×80

=80/4

=20

Therefore, 20 Counters are expected to be marked with a dab of white paint.

Answer:(x+9)(x+3)

(I dont think it matters when it’s switched)

Hope I helped

Step-by-step explanation:

The middle number is 12 and the last number is 27.

Factoring means we want something like

(x+_)(x+_)

We need two numbers that...

Add together to get 12

Multiply together to get 27

Can you think of the two numbers?

Try 3 and 9:

3+9 = 12

3*9 = 27

Fill in the blanks in

(x+_)(x+_)

with 3 and 9 to get...

(X+3)(x+9)

(x+3)(x+9)

Answer:

45

Step-by-step explanation:

A number consists of 2 digits whose sum is 9 => x + y = 9

If the order of the numbers is inverted, the result is equal to the given number plus 9 units => (10*y + x) + 9 = (10*x + y)

Thus:

x + y = 9  => multiply by -9 => 9*y + 9*x = 81

10*y + x + 9 = 10*x + y =>  9*y - 9*x = -9

We are left then that:

9*y + 9*x = 81  (1)

9*y - 9*x = -9  (2)

we add both equations

18y = 72

y = 72/18 = 4

replacing

x + y = 9

x + 4 = 9

x = 5

Therefore the number is (10y + x) => (10 * 4 + 5) => 45

Answer:

[tex] r = \frac{D}{2}= \frac{2.9m}{2}= 1.45 m[/tex]

If we convert the height to meters like this:

[tex] h = 9.6 cm *\frac{1m}{100 cm}= 0.096m[/tex]

And we want to find the volume of the cone and is given by:

[tex] V = \pi r^2 h[/tex]

And replacing we got:

[tex] V = \pi (1.45m)^2 (0.096m) =0.634 m^3 \approx 0.6 m^3[/tex]

Step-by-step explanation:

For this case we have a right circular cone with a height of 9.6cm and a base with a diameter of 2.9m. We can find the radius like this:

[tex] r = \frac{D}{2}= \frac{2.9m}{2}= 1.45 m[/tex]

If we convert the height to meters like this:

[tex] h = 9.6 cm *\frac{1m}{100 cm}= 0.096m[/tex]

And we want to find the volume of the cone and is given by:

[tex] V = \pi r^2 h[/tex]

And replacing we got:

[tex] V = \pi (1.45m)^2 (0.096m) =0.634 m^3 \approx 0.6 m^3[/tex]

Answer:

2/15

Step-by-step explanation:

To solve this problem we just need to use a rule of three, relating the fraction of the scarf knitted and the amount of time.

So we have that:

1/10 of the scarf -> 3/4 hour

x of the scarf -> 1 hour

x * (3/4) = 1/10

x = (1/10) / (3/4)

x = (1/10) * (4/3)

x = 4/30 = 2/15

In one hour, Meagan knit 2/15 of the scarf.

Answer:

[tex]r = 16[/tex], [tex]s = -48[/tex]

Step-by-step explanation:

The values of [tex]r[/tex] and [tex]s[/tex] can be found with the help of algebraic manipulation on the second-order polynomial described on statement:

[tex]f(x) = 3\cdot x^{2} - 24\cdot x + \frac{1}{3}[/tex]

[tex]f(x) = 3\cdot (x^{2} - 8\cdot x) + \frac{1}{3}[/tex]

[tex]f(x) = 3\cdot (x^{2} - 8\cdot x + 16 - 16) + \frac{1}{3}[/tex]

[tex]f(x) = 3\cdot (x^{2}-8\cdot x + 16) + \frac{1}{3} - 48[/tex]

By comparing each expression, the results are presented below:

[tex]r = 16[/tex], [tex]s = -48[/tex]
