A submarine started 30 feet below the surface of the water. It is now 10 feet below the surface. What integer represents the change in depth?

Answers

Answer 1

Answer:

-20 feet

Step-by-step explanation:

change in depth = number of feet below the surface + number of depth on the surface

Because the submarine is below surface, a value of -30 would be given

-30 + 10 = -20 feet

Find the value of x then find the angle measures of polygon

Answers

All the angles equals 360°.

The best way to find x without guessing is to add everything and make an equation.

x°-46°+x°+x°-35°+1/2x°=360°

Add like terms.

3 1/2x°-81°=360°

Answer:

The base of the log is the same as the base of the exponential form and in our case the base is 4. The value of the exponent is what the log is equal too and in our case it is 5. We already know the base is 4 and we want to raise it to the exponent of 5 so we get

[tex]38+7·(x-3)=9·(x+1)[/tex]

Answers

[tex]38 + 7x - 21 = 9x + 9[/tex]

Combine like terms.

[tex]17 + 7x = 9x + 9[/tex]

Eliminate a x.

[tex]17 = 2x + 9[/tex]

[tex]8 = 2x[/tex]

[tex]x = 4[/tex]

38 + 7x - 21 = 9x + 9

7x + 17 = 9x + 9

Subtract both sides 9

7x + 17 - 9 = 9x + 9 - 9

7x + 8 = 9x

Subtract sides 7x

7x - 7x + 8 = 9x - 7x

8 = 2x

Divide both sides by 2

8 ÷ 2 = 2x ÷ 2

x = 4

Step-by-step explanation:

5x²-45=05x²=45x²=9x=√9x=3

hope it helps.

Answer:

x=±√9 or x= 3, x=-3

Step-by-step explanation:

The problem requires us to find the x.

So we must isolate the variable, as so-

[tex]5x^2-45=0\\5x^2=45[/tex] (add 45 to both sides)

Now we can divide both sides by -

[tex]5x^2=45\\x^2=9[/tex]

Now we must square root both sides to find the root of x.

[tex]\sqrt{x^2} =\sqrt{9}[/tex]

x=±√9

or x= 3, x=-3

The length of a swing is 2.1m if the length of the arch that is made by the swing is 4.4m calculate the angle swept by the swing

Answers

Answer:

The angle swept by the swing is 120 degrees

Step-by-step explanation:

Here, we are given the radius of the circle that makes the arc, and the length of the arc

Mathematically, we are to find the central angle

That would be;

The length of an arc is;

theta/360 * 2 * pi * r

theta is the central angle we are looking for and r in this case is 2.1 m

Thus, we have it that;

theta/360 * 2 * 22/7 * 2.1 = 4.4

theta = (360 * 4.4 * 7)/(2 * 22 * 2.1)

theta = 120 degrees

Step-by-step explanation:

Alexandra paid $7dollar to park her car for 3hours at the parking garage. The garage charges a constant hourly parking rate. Write an equation that shows the relationship between p, the number of hours parked, and c, the cost in dollars.

Let the constant = k

The relationship is written as:

c = p×h + k

P = cost of parking

h = Number of hours parked

c = $7 × 3 + k

c = 21 + k
