It is 6x2

Answer:

D.3

Step-by-step explanation:

We are going to use the Slope Formula --> (y2-y1)/(x2-x1)

Answer:

I believe the answer would be the option that says: "An elephant walks with a speed of 15 steps a minute. How long was the elephant walking if she walked without stopping for 480 steps?"

Answer:

C. An elephant walks with a speed of 15 steps a minute. How long was the elephant walking if she walked without stopping for 480 steps?

Step-by-step explanation:

C yields the equation of [tex]15x=480[/tex], because 15 stands for steps/minute, 480 for steps, so [tex]x[/tex] must stand for minutes.

For your entertainment:

A gives [tex]x = 480 \cdot 15[/tex].

B gives [tex]x=32-15[/tex].

D gives [tex]x=480+15[/tex].

Answer:

27/100 because if u write the decimal out in word form it's 27 hundredths and its the same thing if u write 27/100 in word form

Answer:

10 m

Step-by-step explanation:

We are given that the relationship between intensity of sound and distance from the source is given by

Intensity (I)=[tex]\frac{k}{d^2}[/tex]

Where I=Intensity

d=Distance of sound from the source

If distance d=1m

Intensity, I=0.1[tex]w/m^2[/tex]

We have to find how close she can to the stage if vanessa does not want the sound intensity to be more than 0.001(w)/(m^(2)).

Using the formula

[tex]0.1=\frac{k}{1}[/tex]

[tex]k=0.1[/tex]

[tex]\frac{0.1}{d^2}\leq 0.001[/tex]

[tex]\frac{0.1}{0.001d^2}\leq 1[/tex]

[tex]\frac{0.1}{0.001}\leq d^2[/tex]

[tex]100\leq d^2[/tex]

[tex]10\leq d[/tex]

[tex]d=10 m[/tex]

Hence, she can sit 10 m away from the stage.

Answer:

400

The ladder is the hypotenuse of a right triangle. The 2 feet from the wall on the ground is one side, the distance up the wall is another side.

In a right triangle, the square of the hypotenuse is the sum of the squares of the other two sides. This is called the Pythagorean Theorem. In equation form:

c^2 = a^2 + b^2

Substitute the known values:

20^2 = 2^2 + b^2

Square the numbers:

400 = 4 + b^2

Subtract 4 from both sides:

b^2 = 400 - 4 = 396

Take the square root:

b = sqrt(396) = 19.9 (rounded) feet

Check:

20^2 ?= 2^2 + 19.9^2

400 ?= 4 + 396.01

400 ?= 400.01 (off just a bit due to rounding)

Answer:

No, A is

Step-by-step explanation:

You can tell by plugging in the numbers. 0 - 3(0) < 1 as 0 < 1.

============================================================

Explanation:

Let's check if choice C is the answer or not

We will plug in x = -2 and y = 1 into the inequality to get

y - 3x < 1

1 - 3(-2) < 1

1 + 6 < 1

7 < 1

That's a false statement since 7 is not smaller than 1. This means the first inequality is false when (x,y) = (-2,1). So we can rule out choice C. Choices B and D are similar stories.

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

It turns out that choice A is the answer because

y - 3x < 1

0 - 3(0) < 1

0 - 0 < 1

0 < 1

Which is a true statement. So (x,y) = (0,0) is one solution to this inequality.

I'll let you check the other answer choices. You should find them to be false

Answer:

Step-by-step explanation:

Answer:

5y=45 if y=9

Step-by-step explanation:

5y=45 if y=9

5(9)=45

45=45

Answer

I think the answer is 5x^4

Answer:

the weight of 45 bushels is 1.22

Step-by-step explanation:

The computation is shown below:

As the soybeans has the conversion factor of 36.744

So the weight of 45 bushels be

= 45 ÷ 36.744

= 1.22

hence, the weight of 45 bushels is 1.22

Answer:

Its 2 x radius

Step-by-step explanation:

Answer:

Twice the radius length.

Step-by-step explanation:

Generally, the diameter is the length of a line that extends from one point on a circle to another point on a circle as long as that line passes through the center of the circle. Essentially, a diameter, in short, is twice the length of the radius of a circle.

Answer:

i dont know if its right since i havent done trig in ages but

[tex]3 \sqrt{3} [/tex]

Step-by-step explanation:

tan(30)x9?

put the opposite angle inside the () since were doing toa which is tan(sin)=opposite/adj

so if we rearrange the formula to make opposite the subjects its

opposite=tan x adj

this is probably wrong so u might want to check with someone else

Answer:

35.)   80

36.)   11

37.)   15

38.)   21

39.)   -9

40.)   -1

Step-by-step explanation:

In simplified terms the question is asking

35.)   g(f(-1)) =

         g(-9) = 80

36.)   f(g(2)) =

         f(3) = 11

37.)   g(f(0)) =

        g(-4) = 15

38.)   f(g(root6)) =

         f(5) = 21

39.)   f(g(0)) =

         f(-1) = -9

40.)   g(f(4/5)) =

         g(0) = -1
