Answer:

264  {feet}

below sea level

Step-by-step explanation:

Ascending means moving towards the surface.

So the submarine is 340 feet below sea level.

The submarine ascends 76 feet.

∴

340 − 76  =

264  below sea level.

Step-by-step explanation:

Answer:

hat=£(9*9)/3*24)/3/8/9

Scarf=£1.5

Step-by-step explanation:

Let's suppose hats is the variable h

And Let's suppose scarves is the variable s

3h+2s=12

5h+4s=21

so, 3h+2s=12 which is also 2s=12-3h

so, in the equare 5h+4s=21 we can replace the 4s with 2(12-3h) Now the equation is this:

5h+24-6h=21

*Simplified*

Now 5h-6h= -1h

-1h+24=21

+1h      +1h

on each side.

now the equation is(remember 1h=h): 24=h+21

I think you can do it now.

Now with the cost of the hats, we can use the first equation: 3h+2s=12

h=3

3*3=9

-9    -9

2s=3

s=1.5

Answer: C:4x^2 square root of 3x

Step-by-step explanation:

Just got it right on Plato

C.  4[tex]x^{2} \sqrt{3x}[/tex] is equivalent to the expression [tex]\sqrt{48x^{5} }[/tex] if x>0

An algebraic expression may be a blend of constants, coefficients, factors, and scientific operations. An algebraic expression can comprise of a number of terms or a few. Equivalent algebraic expressions are expressions that appear different but work the same way. If two algebraic expressions are equal, then on assigning the same value to the variables the two expressions will give the same value.At least two expressions are required to check for equality and You can substitute in nearly any value for the variable when trying to determine if two expressions are equivalent.

Expression:

[tex]\sqrt{48x^{5} }[/tex]  if x>0

= [tex]48^{1/2}(x^{5})^{1/2}[/tex]

= [tex]48^{1/2}x^{5/2}[/tex]

= (2×2×2×2×3[tex])^{1/2}x^{5/2}[/tex]

= 2×2×[tex]3^{1/2}[/tex]×[tex]x^{5/2}[/tex]

= 4[tex]\sqrt{3} x^{5/2}[/tex]

= [tex]4\sqrt{3}x^{2} x^{1/2}[/tex]

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

Therefore, [tex]\sqrt{48x^5}[/tex] = [tex]4x^{2} \sqrt{3x}[/tex] if x>0

Hence, 4[tex]x^{2} \sqrt{3x}[/tex] is equivalent to the expression  [tex]\sqrt{48x^{5} }[/tex] if x>0

Answer:

A

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

∠ A + ∠ B + ∠ C = 180°, so

95° + 35° + ∠ C = 180

130° + ∠ C = 180 ( subtract 130° from both sides )

∠ C = 50° → A

Answer:

The athlete's tangential velocity is 0.88 m/s.

Step-by-step explanation:

We have that the athlete completes 4 laps around a track with a radius of 25 meters in 12 minutes:

[tex] \omega = \frac{\theta}{t} [/tex]

Where:

ω: is the angular speed

θ: is the angular displacement

t: is the time = 12 min = 720 s

The angular displacement is:

[tex] \theta = 4 rev*\frac{2\pi rad}{1 rev} = 25.13 rad [/tex]

Now, the angular speed is:

[tex] \omega = \frac{\theta}{t} = \frac{25.13 rad}{720 s} = 0.035 rad/s [/tex]

Finally, the athlete's tangential velocity is:

[tex] v = \omega r = 0.035 rad/s*25 m = 0.88 m/s [/tex]

Therefore, the athlete's tangential velocity is 0.88 m/s.

Answer:

2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles

Step-by-step explanation:

1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)

2.) 2 hours: 13.5 * 2 = 27 miles

3.) 3 hours: 13.5 * 3 = 40.5 miles

4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles

9 miles in 2/3 of a hour.

in 1 hour = 9 X 3/2 = 18.2 miles

In 2 hrs = 27 miles

in 3 hrs = 54.6 miles

in 3.5 hrs = 63.7 miles

18x+3y=-21

slope -intercept form: y=mx+b

move 18x to the other side

sign changes from +18x to -18x

18x-18x+3y=-18x-21

3y=-18x-21

divide both sides by 3 to find slope-intercept form

3y/3=-18x/3-21/3

y=-6x-7

The answer is the third one of y = 6x.

As you substitute x = 1, you get y = 6.

You substitute x = 2, you get y = 12.

Answer:

y=x-2

a. 3=x-2

b. this isn't wrong??

c. 3=x-2

d. add 2 to both side so taht x is on its own so 5=x

e. yes

Answer:

C and E

Step-by-step explanation:

Im not entirely sure about A, because you are substituting so technically you changed it but the equation is still true (just as E says) but with more specific values.

B is not right because you can replace either y or x

D is not right because if you switch the equation to get the value of x you would make x= -3-2 which would be -5, not 5.

Answer:

Arc SN = 65

Step-by-step explanation:

The relationship between these three is

RPQ = 1/2 (arc SN + arc QR)

70 = 1/2 (x + 75)                        Multiply by 2

140 = x + 75                              Subtract 75

x = 140 - 75

x = 65

Answer:

The temperature in degrees after 9 hours is -1.25 degrees Fahrenheit

Step-by-step explanation:

Here, we want to know the temperature after 9 hours

Per hour rise each hour is 3/4 degree = 0.75 degree

In 6 hours that will be 0.75 * 6 = 4.5 degrees

Or hour drop is 1/4 = 0.25 degree

In 3 hours, that will be 0.25 * 3 = 0.75 degree

Since it is a drop, we have -0.75 degree

Temperature after 9 hours will be;

-5 + 4.5 -0.75

= -5.75 + 4.5 = -1.25 degrees fahrenheit

The answer is going to be 5162.
