Answer:

The weight for an object with a velocity of 12 meters per second is 600 kilograms

Step-by-step explanation:

Formula of linear momentum : p = mv

where p is the momentum

m = mass

v = velocity

If the velocity is 16 meters per second and the object weighs 450 kilograms

Substitute the values

$p = 16 \times 450$

We are supposed to find the weight for an object with a velocity of 12 meters per second

So, p = 12m

We are given that The linear momentum is a constant when the mass varies inversely of the velocity.

So, $16 \times 450 = 12 m$

$\frac{16 \times 450}{12}=m$

600 = m

So,the weight for an object with a velocity of 12 meters per second is 600 kilograms

Triangle MNO is an equilateral triangle with sides measuring units. What is the height of the triangle? NR units

oksian1 [2.3K]

$\bf \textit{height of an equilateral triangle}\\\\
h=\cfrac{s\sqrt{3}}{2}\qquad 
\begin{cases}
s=\textit{length of a side}\\
---------\\
s=16\sqrt{3}
\end{cases}\implies h=\cfrac{16\sqrt{3}\cdot \sqrt{3}}{2}
\\\\\\
h=\cfrac{16\cdot 3}{2}\implies h=8\cdot 3\implies h=24$

A tank's length is 3 feet longer than its width. The height is 1 foot less than the width. The volume of the tank is 160 cubic f

Ivanshal [37]

Answer:

The width of the tank is <u>5 feet</u>.

Step-by-step explanation:

Given:

A tank's length is 3 feet longer than its width.

The height is 1 foot less than the width.

The volume of the tank is 160 cubic feet.

Now, to find the width of the tank.

Let the width of the tank be $x.$

So, length is $x+3.$

And, height is $x-1.$

The volume of tank = 160 cubic feet.

Now, to get the width we put formula:

Volume = length × width × height.

$160=(x+3)\times x\times (x-1)$

$160 =x(x^2-x+3x-3)$

$160=x(x^2+2x-3)$

$160=x^3+2x^2-3x$

<em>Subtracting both sides by 160 we get</em>:

$0=x^3+2x^2-3x-160$

$x^3+2x^2-3x-160=0$

Now, on solving the equation we get:

$x=5.$

The width = 5 feet.

Therefore, the width of the tank is 5 feet.

When adding 43.8 to a certain number, the sum is 46.59, as seen below. What number should go in the box to complete the addition

Ganezh [65]

43.8 + x = 46.59

x = 46.59 - 43.8 ( when you move a number to the other side, flip the sign)
x = 2.79 (answer)

Solve the equations below. With explanations please.

Sophie [7]

Answer:

Step-by-step explanation:

y=-2x-4

y=5x+5

------------

-2x-4=5x+5

-2x-5x-4=5

-7x-4=5

-7x=5+4

-7x=9

x=9/-7

x=-9/7

y=5(-9/7)+5

y=-45/7+35/7

y=-10/7

Answer: x=-9/7, y=-10/7. (-9/7, -10/7).

----------------------------------------------------

-3x+y=8

2y=6x-10

----------------

6x-2y=10

-3x+y=8

-------------

y=8-(-3x)=8+3x

6x-2(8+3x)=10

6x-16-6x=10

-16=10

no solution

Answer: No Solution

--------------------------------

2y=4(x+3)

y-2x=6

--------------

y=4x+12

y=2x+6

--------------

4x+12=2x+6

4x-2x+12=6

2x+12=6

2x=6-12

2x=-6

x=-6/2

x=-3

y=2(-3)+6=-6+6=0

Answer: x=-3, y=0. (-3, 0).

x+2y=4

4x-2y=16

---------------

5x=20

x=20/5

x=4

4+2y=4

2y=4-4

2y=0

y=0/2

y=0

Answer: x=4, y=0. (4, 0).
