Find the perimeter of a square room with side 12 ft.

Answer:

-20 m/s.

Step-by-step explanation:

The computation of the average speed is shown below:

Given that

The initial velocity of the bus, u = 20 m/s

Aceleration of the bus, -a = 8 m/s²

time of motion, t = 5 s

Now The final velocity of the bus is  

v = u + at

v = 20 + (-8 × 5)

v = 20 - 40

v = -20 m/s.

Step-by-step explanation:

Complete question is;

Zac and Lynn are each traveling on a trip. So far, Zac has traveled 123.75 miles in 2.25 hours. Lynn leaves half an hour after Zac. So far

she has traveled 105 miles in 1.75 hours. Assume Zac and Lynn travel at constant rates.

Let a represent the number of hours that have elapsed since Zac started traveling. Let y represent the number of miles traveled. Write a system of linear equations that represents the distance each of them has traveled since Zac left on his trip.

Assume Zac and Lynn continue to travel at the same constant rates and make no stops.

Determine the solution of the system of linear equations.

Answer:

Zac: y = 55a

Lynn: y = 60(a - ½)

6 hours after Zac started traveling, both Zac and Lynn would have covered 330 miles each.

Step-by-step explanation:

Zac has traveled 123.75 miles in 2.25 hours. Since he travels at constant speed, we can say;

zac's speed = 123.75/2.25 = 55 mi/hr

Similarly, Lynn traveled 105 miles in 1.75 hours. Thus, since she travels at a constant speed;

Lynn's speed = 105/1.75 = 60 mi/hr

Now, we are told that a represents the number of hours that have elapsed since Zac started traveling and y represents the number of miles traveled.

Thus;

a hours after Zac started travelling, his distance covered will be;

Zac: y = 55a

Now,for Lynn, since she started ½ an hour after Zac, it means a hours after Zac started, she had traveled (a - ½) hours.

Thus, Lynn's distance traveled after Zac started = 60(a - ½)

Lynn: y = 60(a - ½)

The solution will be when they have travelled equal distances a hours after Zac started. Thus;

55a = 60(a - ½)

55a = 60a - 30

60a - 55a = 30

5a = 30

a = 30/5

a = 6 hours

Putting 6 for a in y = 55a, we have;

y = 55 × 6

y = 330 miles

Answer:

7.5 metres

Step-by-step explanation:

The formula for the area of a parallelogram is Area = base x height.

In the problem, you are given the base, which is 9.44 metres, and the area, which is 70.8 square metres.

When you plug everything into our area formula, you should get:

70.8 = 9.44 x height

To solve for height, you would divide both sides by 9.44.

70.8 ÷ 9.44 = height

7.5 = height

Don't forget your units, which is metres!

height = 7.5 metres

Answer:

Option A

Step-by-step explanation:

Given expression is,

[tex]4\sqrt{2}-5\sqrt{3}[/tex]

If a radical term is given as [tex]\sqrt[a]{b}[/tex],

Here, a = Index

And b = Radicand

In the given expression radical terms are [tex]\sqrt{2}[/tex] and [tex]\sqrt{3}[/tex].

In these radical terms radicands are 2 and 3, which are not same.

Therefore, expression given can not be simplified further.

Option A will be the answer.

Answer:

g(x) = |x - 2| - 9

Step-by-step explanation:

Translations of a function f(x):

Translation of f(x) by a units to the right is given by f(x - a).

Translation of f(x) by a units to the left is given by f(x + a).

Translation of f(x) by a units down is f(x) - a

Translation of f(x) by a units up is f(x) + a

Find g(x), where g(x) is the translation 2 units right and 9 units down of f(x)=|x|.

2 units right: f(x - 2) = |x - 2|

9 units down: f(x - 2) - 9 = |x - 2| - 9

The answer is: g(x) = |x - 2| - 9

Answer:

[tex]Height =3[/tex]

Step-by-step explanation:

Given

[tex]Length = x + 2[/tex]

[tex]Width = x - 2[/tex]

[tex]Height = x[/tex]

[tex]Volume = 15[/tex]

Required

Find the height

The volume is calculated as thus:

[tex]Volume = Length * Width * Height[/tex]

This gives

[tex]15 = (x + 2) * (x - 2) * x[/tex]

Apply difference of two squares

[tex]15 =(x^2 - 4 ) * x[/tex]

[tex]15 = x^3 - 4x[/tex]

Subtract 15 from both sides

[tex]x^3 - 4x - 15 = 0[/tex]

Using a calculator to factorize, we have:

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

Split

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

[tex]x = 3[/tex] or  [tex]x^2 + 3x + 5 = 0[/tex]

x has complex roots for [tex]x^2 + 3x + 5 = 0[/tex]

Hence:

[tex]x = 3[/tex]

Recall that:

[tex]Height = x[/tex]

[tex]Height =3[/tex]

Answer:

199.5in^3

Step-by-step explanation:

To do this we first need to find the area of the triangle to do that we can do 3.5*2=7

(since there are two triangles we can do it like this to make it easy)

then we can multiply it like so

7*28.5=199.5

Hope this helps :)

The applicable rule of exponents seems to be ...

  (a^b)^c = a^(bc)

  a^-b = 1/a^b

Answer:

30,000

Step-by-step explanation:

The computation of the working capital is shown below:

As we know that

Working capital = current assets - current liabilities

where

Current assets = Cash at bank + stock + debtors

= 12,000 + 18,000 + 24,000

= 54,000

And, the current liabilities = bill payable + creditors

= 7,000 + 17,000

= 24,000

So, the working capital is

= 54,000 - 24,000

= 30,000

Answer:

7 sides

Step-by-step explanation:

The sum of exterior angles of a polygon is 360°.

Now, exterior angle of the point with interior angle of 120 is; 180 - 120 = 60 (angle on a straight line)

For the others, it is; 180 - 130 = 50

Thus;

60 + 50n = 360

50n = 360 - 60

50n = 300

n = 300/50

n = 6

Thus,number of sides = 6 +1 = 7 sides

Answer:

1.30g

Step-by-step explanation:

The mass of 8 seed pods is equal to 10.4g.

10.4g = 8 pods

Total mass / Total pods = Individual pod weight

10.4g / 8 pods = 1.30g per pod

Lets check our work to confirm:

1.30g x 8 pods = 10.4g
