An oil tank has to be drained for maintenance. The tank is shaped like a cylinder that is 4 ft long with a diameter of 2.2 ft. Suppose oil is drained at a
rate of 1.5 per minute. If the tank starts completely full, how many minutes will it take to empty the tank?
Use the value 3.14 for, and round your answer to the nearest minute. Do not round any intermediate computations.

Answers

Answer 1

Answer:

[tex]8\:\mathrm{minutes}[/tex]

Step-by-step explanation:

The volume of a cylinder is given as:

[tex]r^2\cdot\pi\cdot h[/tex]

Since the diameter is [tex]2.2[/tex], the radius is [tex]\frac{2.2}{2}=1.1[/tex].

Therefore, the volume of this cylinder is:

[tex]1.1^2\cdot 3.14\cdot 4=15.1976\:\mathrm{ft^3}[/tex], using [tex]\pi=3.14[/tex] as requested in the problem.

Since the tank is emptied at a constant rate of [tex]1.5\:\mathrm{ft^3\:per\:minute}[/tex], it will take

[tex]\frac{15.1976}{1.5}=7.5988=\fbox{$8\:\mathrm{minutes}$}[/tex] to empty the tank.

which equation represents the graphed function? ​

Answers

Answer:

[tex]\frac{3}{2}[/tex] x - 3 = y

Step-by-step explanation:

The answer is the third equation.

This is because the y-intercept is -3 and the x-intercept is at (2,0) (you can find the x-intercept by making "y" = 0). The only equation that has both of these is the third one.

Find the values of x and y.

Answers

Answer:

x = 20 (degrees)

y = 70 (degrees)

Step-by-step explanation:

The angle adjacent to the one labeled 40° is supplementary, so it would measure 140°. And the obtuse triangle is an isosceles, which means that x is half of 180° - 140°, so x = 1/2(40°) = 20°

To find y, subtract 90° and x from 180°

y = 180° - 90° - 20°

y = 70°

Answer:

x = 20 and y = 70

Step-by-step explanation:

x = 20 and y = 70

Solve for x.
3(3x+3)-5x-4= 25

Answers

3(3x + 3)-5x - 4 = 25
9x + 9 - 5x - 4 = 25
4x + 5 = 25
4x + 5 - 5 = 25 - 5
4x = 20
4x/4 = 20/4
X = 5

Answer:

3(3x + 3) - 5x - 4 = 25

9x + 9 - 5x - 4 = 25

9x - 5x - 4 = 16

4x - 4 = 16

4x = 20

x = 5

All 3 sides of the triangle are the same, which means all 3 inside angles are the same. Each inside angle is 60 degrees.

We now have 3x = 60

Divide both sides by 3:

x = 60/3

x = 20

Answer:

As in the given figure, all the sides are equal i.e., 5 units

It is a equilateral triangle.

In equilateral triangle all the angles are 60°.

[tex]3x = 60 \\ x = \frac{60}{3} \\ \boxed{x = 20}[/tex]

20 is the right answer.

Yesterday a chef used 36 eggs to make 8 chocolate souffles and 3 lemon meringue pie. The day before, he made 2 chocolate souffles and 2 lemon meringue pies, which used 14 eggs. How many eggs does each dessert require?

Write the system. Define your variables.
plshelpme¡¡¡¡1

Answers

Answer: Well first one chocolate souffles uses 3 eggs and each lemon maringue uses 4

Step-by-step explanation: First what i did was look at the question and it shows that there is two sets, so you have to plug in some random numbers and i started at o and if you do 8*1 you would have 1 egg per each souffles and you would have 28 eggs left and that won't work because 28/3 gives some long and then i tried 2... and 8*2 is 16 so you would have 20 eggs left and of course another long answer. But if you try three, 8*3 it gives you 24 so 36-24 and you get 12 and 3*4 is 12.. so then i plugged the same numbers in for the second part.. 3*2=6 and 4*2=8 and 6+8=14

Which of the following describes the solutions to the equation above?
A)The equation has two distinct rational solutions.
B)The equation has two distinct irrational solutions.
C)The equation has one distinct real solution.
D)The equation has no real solutions.

Answers

Answer:a

Step-by-step explanation:

The solutions to the given equation will be two distinct rational solutions, i.e. option A.

What is expression ?

Expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

We have,

[tex]2x ^2 -5=3x[/tex]

Now,

Rearrange the equation,

[tex]2x ^2 -3x-5=0[/tex]

Now,

Using the mid term splitting method,

[tex]2x ^2 -3x-5=0[/tex]

i.e.

[tex]2x ^2 -5x+2x-5=0[/tex]

Now,

Taking common,

[tex]2x ^2 +2x-5x-5=0[/tex]

i.e.

[tex]2x (x +1)-5(x+1)=0[/tex]

We get,

[tex](x +1)(2x -5)=0[/tex]

Now,

(x +1) = 0

⇒ x = -1

Now,

(2x -5 )= 0

⇒ [tex]x =\frac{5}{2} =2.5[/tex]

So, the solutions of the given equation are -1 and 2.5.

Hence, we can say that the solutions to the given equation will be two distinct rational solutions, i.e. option A.

However, the corner of 7th Street and 7th Avenue is blocked due to construction and you cannot get through. How many ways are there to walk to meet your friend?

Step-by-step explanation:

To get from point (4,4) to (10,10), it is the same as ordering 6 Upward and 6 Right arrows in a straight line.

=> 12C6 = 924.

However there is a restriction that we cannot have 3 Upward and 3 Right arrows as our first 6 arrows.

=> 6C3 * 6C3 = 20 * 20 = 400

Hence there are 924 - 400 = 524 different ways.
