Answer:

non-equivalent

Step-by-step explanation:

the equivalend fraction of [tex]\frac{2}{3}[/tex] is [tex]\frac{6}{9}[/tex] not [tex]\frac{6}{10}[/tex]

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

use Cos for y .... b/c we see that function above has all the pieces we are going to work with

use Sin for x .. for the same reason above

Cos(30) = y / 4[tex]\sqrt{2}[/tex]

4[tex]\sqrt{2}[/tex]Cos(30) = y

4[tex]\sqrt{2}[/tex][tex]\sqrt{3}[/tex]/2 = y

2[tex]\sqrt{6}[/tex] = y

leave the answer for y like that.. it's in  'exact" form

now for x

Sin(30) = x / 4[tex]\sqrt{2}[/tex]

4[tex]\sqrt{2}[/tex]Sin(30) = x

4[tex]\sqrt{2}[/tex]* 1/2 = x

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

and leave your answer for x like that as it's in it's exact form.  :)

oh and I see the answer in the list.. do you?  :)

there you go!! it's correct dont worry

Answer:

m= -0.25 b=2.25 the answer is -0.25

A slope is also known as the gradient of a line. The slope of the line is -0.25. The correct option is B, -0.25.

A slope is also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

The two points of the graph are given as (-3,3) and (1,2). Now, the slope of the line can be written as,

Slope = (3 - 2) / (-3 - 1)

          = 1/-4

          = -0.25

Hence, the slope of the line is -0.25.

Answer:

the answer is 2

Step-by-step explanation:

sorry if this is wrong

Step-by-step explanation:

Here's your solution

=> Base = 32 In

=> Height = 30 in

=> Area of traingle = 1/2*base *height

=> putting the value of base and height in formula

=> Area = 1/2*30*32

=> Area = 480 in sq

Answer:

A. Transform Boundary

Step-by-step explanation:

Transform boundaries are places where plates slide sideways past each other

Divergent Boundaries occur  when two tectonic plates move away from each other

Convergent Boundaries are when both the plates collide into each other

Subduction boundaries are when one plate bends and slides underneath the other curving down into the mantle

Answer:

Surface area = 10.7 in.²

Step-by-step explanation:

Surface Area of triangular pyramid = BA + P*L

Base Area (BA) = ½*nh

b = 2 in.

h = 1.7 in.

BA = ½*2*1.7 = 1.7 in.²

Perimeter (P) = 2 + 2 + 2 = 6 in.

Slant height (L) = 3 in.

Plug in the values

Surface Area = 1.7 + ½*6*3

Surface area = 10.7 in.²

Answer:

See the explanation

Step-by-step explanation:

When the numerator is less than the denominator, the result is always less than 1, that is 0. something and this will give a percentage less than 100, but when the numerator is greater than the denominator, th result is greater than 1, and any figure greater than 1 gives a percentage that is greater than 100

example

Numerator >Denominator

=4/2*100

=2*100

=200%

Numerator <Denominator

=2/4*100

=0/5*100

=50%

Answer:

Step-by-step explanation:

I'll assume that all the angles are 90°, and there is no bottom to the box.

To determine the wood needed, calculate the surface area of the bed. Since there is no bottom or top to the box, the amount of wood is 2(45 in × 21 in) + 2(22 in × 21 in) = 1890 in² + 924 in² = 2814 in²

To determine the soil needed, calculate the volume of the box.

volume = 45 in × 21 in × 22 in = 20,790 in³

Answer:

[tex]P(Both) = \frac{3}{25}[/tex]

[tex]P(One) = \frac{12}{25}[/tex]

[tex]P(None) = \frac{22}{25}[/tex]

Step-by-step explanation:

Given

[tex]P(H) = \frac{3}{5}[/tex]

[tex]P(W) = \frac{1}{5}[/tex]

Solving (a): Both selected

[tex]P(Both) = P(H) * P(W)[/tex]

[tex]P(Both) = \frac{3}{5} * \frac{1}{5}[/tex]

[tex]P(Both) = \frac{3}{25}[/tex]

Solving (b): One selected.

This event can be represented as: HW' or H'W

So:

[tex]P(One) = P(H) * P(W') + P(H') * P(W)[/tex]

Where:

P(W') = 1 - P(W) and P(H') = 1 - P(H).

So:

[tex]P(One) = \frac{3}{5} * \frac{4}{5} + \frac{2}{5} * \frac{1}{5}[/tex]

[tex]P(One) = \frac{12}{25} + \frac{2}{25}[/tex]

[tex]P(One) = \frac{12}{25}[/tex]

Solving (c): None selected.

This is the complement of (a) above.

i.e.

[tex]P(None) = 1 - P(Both)[/tex]

[tex]P(None) = 1 - \frac{3}{25}[/tex]

[tex]P(None) = \frac{25 - 3}{25}[/tex]

[tex]P(None) = \frac{22}{25}[/tex]

Answer:

370 million

Step-by-step explanation:

In the 10 years from 2000 to 2010, the population was multiplied by the factor ...

100% + 9.6% = 109.6% = 1.096

In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:

2030 population = (308 million)·(1.096²) ≈ 370 million

-your welcome and have a great day!!

Let be a1 = 8 and a2 = 8 [ From question ]

We have to find out common differences which denoted by letter d .

d = a2 - a1 [ Formula ]

= 8 - 2

= 6

Thus,the common difference between successive terms in the sequence is 6 .

Answer:

6.

Step-by-step explanation:

We have to find out common differences which denoted by letter d .

d = a2 - a1 [ Formula ]

= 8 - 2

= 6

Also,

2+6=8 +6=14 +6=20 +6=26

So, It's Added Up By 6.
