An electric motor pumps water into a pool at a rate of 500 liters per hour. After a tune up, its rate increases by x liters per hour. If the motor now takes 3 hours to pump 1800 liters, in which equation does x represent the increase in speed after the tune up?

Answer:

The volume of the figure is 20,925.0mm^3.

Step-by-step explanation:

Firstly we know that the Diameter = 14mm and Height = 136mm.

Area of Circle = 3.14xR^2    Radius = Diameter / 2

Area of Circle = 3.14x7mm^2 = 153.86mm

Volume = 153.86 x 136 = 20,924.96

Then round, to get 20,925.0

Let me know if this is helpful

Answer:

Volume : ( About ) 20925 mm^3

Step-by-step explanation:

1. If the diameter of this cylinder is 14 mm, the radius ⇒ 14/2 ⇒ 7 mm

2. Now knowing the radius, it would be most convenient to solve for the Base, which is in fact a circle. As we can see, the general Volume of a 3-dimensional figure is Base * height, so this will be helpful. Applying πr^2, Base Area ⇒ π * ( 7 )^2 ⇒ π * 49 π ⇒ 153.86 mm^2

This means that the Volume would be ⇒ Base Area * height ( where height is 138 mm ) ⇒ 153.86 mm^2 * 136 mm ⇒ 20924.96 mm^3

Answer ( Volume ) : ( About ) 20925 mm^3

Answer:

Step-by-step explanation:

Volume of a square based pyramid = [tex]\frac{1}{3}a^{2}h[/tex] where;

a² is the base area of the pyramid since it is square shaped

h is the slant height.

Given Base area = 144m² and Volume = 384m³, on substituting this values given in the formula we have;

[tex]384 = \frac{1}{3}*144h \\cross\ multiplying\ \\384*3=144h\\h = \frac{384*3}{144} \\h = \frac{1,152}{144}\\ h = 8m[/tex]

The slant height of the pyramid is 8m

Answer:

Next coat sold as medium: 68/190 (35.79%) Rounded to the nearest hundredth) or reduced fraction form of 34/95.

Step-by-step explanation:

Red Medium: 21/58 ( 36.21%)

Navy Medium: 22/66 (33.33%

Tan Medium: 25/66 (37.88%)

Since it's asking for the probability that the next coat is a medium, no matter the color, we add in all numbers and divide it by the added medium from all three colors.

Next coat sold as medium: 68/190 (35.79%) Rounded to the nearest hundredth) or reduced fraction form of 34/95.

Answer:

70

Step-by-step explanation:

A triangle angles add up to 180 so you add up 70 and 40  and then subtract that answer from 180 and you get 70

Answer:

70 degrees.

All three sides of a triangle added together will equal 180 degrees. If 70 and 40 are added together then you get 110. Then you subtract the total 180 and the two angles that equal 110. You get 70 degrees, which is your missing angle.

Answer:

1/9

Step-by-step explanation:

[tex]3^{-2}[/tex] =1/3²=1/9

Answer:

1) 30 units³

2) 18 units³

Step-by-step explanation:

1) The formula for volume is v = height x length x width

The height of the first object is 2, the length is 5, and the width is 3.  2 x 5 x 3 is 30, so the volume is 30 units ³.

2) Use the same formula, v = h x l x w

The height is 3, the length is 3, and the width is 2.

3 x 3 x 2 = 18

So the volume is 18 units³.

Note: Find each of the values by counting the number of squares

Answer:

$562.43

Step-by-step explanation:

V(3) = [tex]500 ( 1 + \frac{0.04}{1} )^{3} \\500 (1.04)^{3}[/tex]

     = 562.43

The interest is $562.4 compounded annually.

Compound interest is defined as interest paid on the original principal and the interest earn on interest of principal.

P = $500

r = 4%

t = 3 years

CI = P( 1+ r/100)ⁿ

CI = 500 ( 1+ 4/100)³

CI = 500 ( 1+ 0.04)³

CI = 500 ( 1.04)³

CI = 500 ( 1.1248)

CI = 562.4

Hence, the interest is $562.4 compounded annually.

Answer:

63 students said yes.

Step-by-step explanation:

105/5= 21

21*3= 63

Answer:

C = 63

Step-by-step explanation:

We know that there are 105 students, so we will take the total amount of students and multiply by 3/5, since this is the probably rate is which say yes. in other words --> 105 * 3/5 = 63

Answer:

15 sqrt(2) =c

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

The legs are 15 and the hypotenuse is the diagonal

15^2 + 15^2 = c^2

2 * 15^2 = c^2

Take the square root of each side

sqrt(2 * 15^2 )=sqrt( c^2)

sqrt(2) sqrt(15^2) = c

15 sqrt(2) =c

Answer: 15[tex]\sqrt{2}[/tex] (b)

Step-by-step explanation:

You can separate a square into two different 45-45-90 degree triangles.

Where x = 15, and the diagonal would be the hypotenuse.

So, here you can use the Pythagorean Theorem to find the hypotenuse to use 45-45-90 triangle theorem where they hypotenuse is always x times [tex]\sqrt{2}[/tex]

So, the diagonal would be 15[tex]\sqrt{2}[/tex]

Answer:

30 degrees

Step-by-step explanation:

A circle is 360 degrees

It is divided into 12 parts

So...

360 divided by 12

equals

30!

Answer: I think its 30 not 100 percent sure

Answer:

Step-by-step explanation:

Here we have the length of the hypotenuse (16) and that of the vertical leg (11).  The cosine function inputs this data:

            adjacent side                11

sin x = -----------------------  =  ----------------  =  0.6875

              hypotenuse                 16

We find x using the arccos function:  arccos 0.6875 = 0.81 radians or

                                                                                          46.57 degrees
