Answer:

28 ft below the surface.

Step-by-step explanation:

A scuba diver was 53 below the oceans surface. If he rises 25 feet, what is the new depth?

    You subtract 25 ft from 53 ft leaving you with 28 ft.

      53 ft

   - 25 ft

       28 ft  below the surface

Answer:

-9

Step-by-step explanation:

Since 5 can go into 40 9 times, the answer would be nine, but by following negative rules, since we have an odd amount of negative numbers in this equation, the answer is -9

Answer:-8

Step-by-step explanation:

5 goes into -40 8 times. 5 goes into 45 9 times.

Answer:

8

Step-by-step explanation:

When there are 2 minuses, they convert into + so that the ewuation turns into:

x+15=23

Then you move the +15 after the = sign

Now that you changed the side, you have to change sign so :

x= 23-15

x=8

Answer:

107%

Step-by-step explanation:

$14 to $29

Original number/start = $14

End number = $29

Increase = $29 - $14 = $15

% increase = Increase ÷ Original Number × 100

Substitute in known values

% increase = 15 ÷ 14 × 100

Divide

% increase = 1.07 × 100

Multiply

% increase = 107%

The percentage increase is 107%

Hope this helps :)

Answer:

107%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

new number = 29; old number = 14

percent change = (29 - 14)/14 * 100%

percent change = 15/14 * 100%

percent change = 107%

your looking for the halfway so the distace apsrt was 8 you divide that by 2 to get 4

Answer:

third one and the 2nd ? is 4

Step-by-step explanation:

complementary =180

between 8 and -2 is 4

Answer: 14

Step-by-step explanation:

To find the distance, find the difference in the x and y values,square them and add them. Then finally find the square root of the number you got after adding them together.  

-2-(-1)= -1

-8 -6 = -14

-14^2 + -1^2 = d^2  where d is the distance

196 + 1 = d^2

197 = d^2

d= [tex]\sqrt{197}[/tex]  

d= 14.0356     rounded to the nearest tenth is 14.

Answer:

18 inches and 57 inches

Step-by-step explanation:

The diameter and the circumference of a circle are proportionate to each other.

The circumference of a circle will always be the diameter times [tex]\pi[/tex]. We know this because the circumference of a circle is represented as

[tex]2 \pi r[/tex]

Since the diameter is twice the radius, we multiply the radius by 2 - there's already a [tex]\cdot 2[/tex] in this equation, so [tex]c = \pi d[/tex].

1st option: [tex]18\cdot3.14 = 56.52[/tex], this is close to 57 so it's reasonable.

2nd option: [tex]3\cdot 3.14 = 9.42[/tex], this isn't close to 28 at all.

3rd option: [tex]33 \cdot 3.14 = 103.62[/tex], this isn't close to 80 at all.

So the 1st option is reasonable.

Hope this helped!

Answer:

First option: 18 inches diameter, 57 inches circumference

Step-by-step explanation:

Circumference of a circle is...

2 * radius * pi

We can approximate pi (3.14159...) to 3.

So the circumference of a circle is approx.

2 * radius * 3

We know the diameter of a circle is 2 times the radius...

diameter = 2 * radius

Thus, the circumference of a circle is approximately...

diameter * 3

First option:

Diameter 18, circumference 57

Let's try our approximation

18 * 3 = 54

We see that 57 is pretty close and is a reasonable approximation.

Second option:

Diameter 3, circumference 28

3 * 3 = 9

Not even close to 28.

Third option:

Diameter 33, circumference 80

3 * 33 = 99

Closer, but much further off than our first option.

Answer:v = 9

Step-by-step explanation:

Simplifying

2(3v + 8) = 70

Reorder the terms:

2(8 + 3v) = 70

(8 * 2 + 3v * 2) = 70

(16 + 6v) = 70

Solving

16 + 6v = 70

Solving for variable 'v'.

Move all terms containing v to the left, all other terms to the right.

Add '-16' to each side of the equation.

16 + -16 + 6v = 70 + -16

Combine like terms: 16 + -16 = 0

0 + 6v = 70 + -16

6v = 70 + -16

Combine like terms: 70 + -16 = 54

6v = 54

Divide each side by '6'.

v = 9

Answer: the answer is 9

Step-by-step explanation:

1. open the bracket by multiplying: 2(3v+8)=70

6v+16=70

2. take the 16 over the equals sign.  note:(the plus sign in front of the 16 changes to a minus sign.)

6v=70-16

6v=54

3. divide both sides by 6

6v/6=54/6

final answer: v=9

Answer:

Step-by-step explanation:

Trust me I know  say thanks ppl

An altitude of a three-dimensional object is best described as option D, "a segment that is perpendicular to the planes containing the two bases."

3D geometry is the study of shapes in 3D space using three coordinates: x-coordinate, y-coordinate, and z-coordinate. To discover the exact location of a point in 3D space, three criteria are required.

An altitude is a line segment drawn from a vertex of a three-dimensional object (such as a pyramid or cone) that is perpendicular to the plane including the base of the object. The altitude can be used to find the height of the object, which is the distance from the vertex to the base along the altitude.

For example, in a pyramid, the altitude is a line segment drawn from the apex (the top vertex) to the center of the base that is perpendicular to the base. In a cone, the altitude is a line segment drawn from the apex to the center of the circular base that is perpendicular to the base.

Answer: 6

Step-by-step explanation:

So to find the answer, we would use the equation 32+4x=56 where as x represents the amount of strawberries Sameer ate. Now to solve for x

56-32=4x

24=4x

now divide 4 from bboth sides of the equation getting:

x=6

so Sameer ate 6 strawberries

Answer:

21 minutes

Step-by-step explanation:

Given the following :

Taking CITY STREET:

Time taken to drive to nearest bowling alley = 45 minutes = 45/60 = 0.75 hours

Speed of travel = 30 miles per hour

Taking FREEWAY:

speed of travel = 65miles per hour

If the distance to bowling alley is the same along both routes, The time taken along FREEWAY will be :

.

Distance to bowling alley taking city center :

Speed = distance / time

30 mph = distance / 0.75 hour

Distance = 30 × 0. 75 = 22.5 miles

Since distance is the same :

Time taken along FREEWAY :

Time taken = distance / speed

Time taken = 22.5 / 65 = 0.3461538 hour

Converting to minutes :

0.3461538 × 60 = 20.769 minutes

= 21 minutes ( to the nearest minute)

First, add 4x to both sides:

10 - 4x (+4x) = -9x (+4x)

10 = -9x + 4x

10 = -5x

Isolate the variable, x. Divide -5 from both sides:

-5x = 10

(-5x)/-5 = (10)/-5

x = 10/-5

Answer:

See below.

Step-by-step explanation:

This is a parabola. Therefore, it is a quadratic parent function. The quadratic parent function is:

[tex]f(x)=x^2[/tex]

The domain of the parent quadratic function is all real numbers.

The range of the parent quadratic function is all y-values greater than or equal to 0. From the graph, we can see that the graph never goes below 0.

So, the domain in interval notation is:

[tex](-\infty,\infty)[/tex]

And the range in interval notation is:

[tex][0,\infty)[/tex]

This is interpreted as all values greater than or equal to 0.

And we're done!

Answer:

8 inches

Step-by-step explanation:

Oliver rolls his ball 1/9th of the distance Fabienne rolls his, so just divide 72 by 9 to get your answer.

Answer:

Oliver rolls his ball 8 inches.

the equation that was used to solve this was : 9n = 72 inches.

Step-by-step explanation:

Since the 72 inches was nine times the distance that Oliver rolled his ball, it means that the unknown number (n), was multiplied by 9 to get Fabienne's inches. So, 9n = 72.

divide both sides by the number next to the unknown to get (n), the number of inches that Oliver rolled his ball.... which is 8.
