5/6 divided by 10/21,

get the reciprocal of 10/21

reciprocal of 10/21=21/10

now.

5/6 x 21/10

5 x 21= 105

6 x 10 = 60

Answer:

243, 729

Step-by-step explanation:

The pattern is to multiply the number by 3 to get to the next number

Example : 1 x 3 = 3 (second number), 3 x 3 = 9 (third number), 9 x 3 = 27 (fourth number)

Following the pattern, the next 2 numbers should be : 81 x 3 = 243, and 243 x 3 = 729

Answer:

I would need to see the graph

Step-by-step explanation:

To find the x-intercept you find the point which the line intercepts with the x-axis...... The x-axis is the one that runs side to side.

Answer:

0,4 and 0, -1

Step-by-step explanation:

The graph is showing the x-axis on the left side. If you look at all the other numbers, they all say x-axis that does not hit the line. Yes, there are numbers who are hitting the 0 point, but all of those are Y-AXIS.

Answer:

Step-by-step explanation:

1) 5xy - xy + 2x - 13x + 10xy - 8x = 5xy - xy + 10xy   +2x - 13x - 8x

Combine like terms

 =  (5 -1 +10)xy + (2-13-8)x

 = 14xy + (-19x)

 = 14xy - 19x

2) -6c - (-6c) - (+6c) = -6c + 6c - 6c

                               = (- 6 + 6 - 6)c

                                = -6c

3) 0x - 22x - 4(2x) = 0x - 22x - 8x = -30x

Solution:

Note that:

Using the perimeter of the smaller triangle, solve for x.

The length of x is 2 units.

Answer:

a)(0, 3)

b)(-3/2, 0)

Step-by-step explanation:

a) y-axis : x=0

so instead of x you write 0 : y = 2 * 0 + 3

and you get y = 3

b) x-axis : y=0

so instead of y you write 0 : 0 = 2 * x + 3

2 * x = -3

x = -3/2

Answer: hose Is raled to fill Ihe pool in 10 hours erhe To fill a pool, Barb uses two hosesThe first third hose that uses {ha slower to fill it in 5 hours. If Barb adds second hose is rated "long will it take to fill the pool?

Give Brainliest! Thanks.

It will take 10/3 hours to fill the pool when both the hoses will work together.

The first hose is rated to fill the pool in 10 hours.

This means, In one hour hose will fill 1/10th part of the pool.

The second hose is rated to fill the pool in 5 hours

This means, In one hour hose will fill 1/5th part of the pool.

The total part of the pool to be filled will be 1.

Let us suppose both the hoses working together takes t hours to fill the pool

So, the first hose will fill the t/10th part of the pool.

The second hose will fill the t/5th part of the pool.

So, [tex]\frac{t}{10} +\frac{t}{5} =1[/tex]

15t =50

t=10/3

Therefore, It will take 10/3 hours to fill the pool when both the hoses will work together.

Answer:

c. 18 feet

Step-by-step explanation:

The area is 180ft². The height is 10ft.

Now, we need to divide 180ft² by 10ft.

180/10 = 18

ft²/ft = ft

The length of the wall is 18ft.

Answer:

The measure of the wall given is square ft., meaning you can divide it by either length or height to get the corresponding side.

We are given a height of 10 ft.

So 180 / 10 = 18ft

L = 18ft

Have a lovely day!

(i) If we can write c as a linear combination of a and b, then there exist scalars k₁ and k₂ such that

[tex]c = k_1a + k_2b[/tex]

Solve for k₁ and k₂ :

[tex]3u + 4v = k_1 (3u - v) + k_2 (-u + 2v)[/tex]

[tex]3u + 4v = (3k_1 - k_2) u + (-k_1 + 2k_2) v[/tex]

Then we must have

[tex]\begin{cases}3k_1 - k_2 = 3 \\ -k_1 + 2k_2 = 4\end{cases} \implies k_1 = 2, k_2 = 3[/tex]

and so

[tex]\boxed{c = 2a + 3b}[/tex]

(ii) Given that u and v form an angle of 60° between them, we have by the dot product identity

[tex]u \cdot v = \|u\| \|v\| \cos(60^\circ)[/tex]

where ||u|| denotes the magnitude of the vector u. Both u and v are unit vectors, so ||u|| = ||v|| = 1, and

[tex]u \cdot v = \dfrac12[/tex]

A special case of the identity with u = v tells us that for any vector u,

[tex]u \cdot u = \|u\|^2 \cos(0^\circ) = \|u\|^2[/tex]

which means

[tex]u \cdot u = v \cdot v = 1[/tex]

This in turn means we have

[tex]a \cdot a = (3u - v) \cdot (3u - v) = 9 (u \cdot u) + (v \cdot v) - 6 (u \cdot v) = 7[/tex]

[tex]a \cdot b = (3u - v) \cdot (-u + 2v) = -3 (u\cdot u) - 2 (v \cdot v) + 7 (u \cdot v) = -\dfrac32[/tex]

[tex]a \cdot c = (3u - v) \cdot (3u + 4v) = 9 (u\cdot u) - 4 (v\cdot v) + 9 (u \cdot v) = \dfrac{19}2[/tex]

[tex]b\cdot b = (-u + 2v) \cdot (-u + 2v) = (u \cdot u) + 4 (v\cdot v) - 4 (u \cdot v) = 3[/tex]

[tex]b\cdot c = (-u + 2v) \cdot (3u + 4v) = -3 (u\cdot u) + 8 (v\cdot v) + 2 (u\cdot v) = 6[/tex]

[tex]c \cdot c = (3u + 4v) \cdot (3u + 4v) = 9 (u\cdot u) + 16 (v\cdot v) + 24 (u\cdot v) = 37[/tex]

and hence

[tex]d \cdot d = (3a + 2b + c) \cdot (3a + 2b + c)[/tex]

[tex]d \cdot d = 9 (a\cdot a) + 4 (b\cdot b) + (c \cdot c) + 12 (a\cdot b) + 6 (a\cdot c) + 4 (b\cdot c)[/tex]

[tex]d\cdot d = 175[/tex]

and so ||d|| = √175 = 5√7.

Step-by-step explanation:

the circumference of a circle is

C = 2 × pi × r

r = radius = diameter / 2

diameter = 2r

in our case

30×pi = 2×pi×r

30 = 2r = diameter

Step-by-step explanation:

Rotation 180° about the origin is equivalent to reflection across the origin. Effectively, every coordinate changes sign.

  (x, y) ⇒ (-x, -y) . . . . rotation 180°

__

Additional comment

There are numerous approaches to making the plot of the reflected image. We chose to plot one point, then develop the rotated image by plotting other points in their proper relative position.

There are geometry programs and apps that can reflect a figure across any point you might choose. They will also do the rotation, if you find that simpler.

You can, of course, compute the values of each of the rotated coordinates, and then plot the points at their new location. We judge that to be the most work of all. YMMV
