Note: The height of the room must be 3 m instead of 3 cm because 3 cm is too small and it cannot be the height of a room.

Given:

Perimeter of the floor of a room = 18 metre

Height of the room = 3 metre

To find:

The area of 4 walls of the room.

Solution:

We know that, the area of 4 walls of the room is the curved surface area of the cuboid room.

The curved surface area of the cuboid is

[tex]C.S.A.=2h(l+b)[/tex]

Where, h is height, l is length and b is breadth.

Perimeter of the rectangular base is 2(l+b). So,

[tex]C.S.A.=\text{Perimeter of the base} \times h[/tex]

Putting the given values, we get

[tex]C.S.A.=18\times 3[/tex]

[tex]C.S.A.=54[/tex]

Therefore, the area of 4 walls of the room is 54 sq. metres.

Answer:

m = 3/17

Step-by-step explanation:

M = -1y/-11c + 16y/-8x = 3/17

Answer:

0.01%

Step-by-step explanation:

y=a (0.5)^t/5730

y=a [(0.5)^t/5730]

when you put 0.5^1/5730

it'll give you 0.99

The "equation" is y=a(1-r)^t

so 1-0.99 is 0.01

The percent of carbon-14 released each year will be 50.

Consider the function:

y = a (1 ± r) ˣ

Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

If there is a plus sign, then there is exponential growth happening by r fraction or 100r %.

If there is a minus sign, then there is exponential decay happening by r fraction or 100r %.

The equation is given below.

[tex]\rm y= a \left ( 0.5 \right )^{t/5730}[/tex]

Where 'a' is the initial amount (in grams) and 't' represents the number of years.

The equation is also written as,

[tex]\rm y= a \left ( 0.5 \right )^{t/5730}\\\\\rm y= a \left ( 1 - 0.5 \right )^{t/5730}[/tex]

The percent of carbon-14 released each year will be 50.

Why dont you just do the steps

Step-by-step explanation:

First you have to add it all together then take your second number, aka 35 which gives you

35/53 which then you just get your fraction from that

Probability of next customer paying cash is [tex]\frac{35}{53}[/tex].

Given that,

According to the scenario, computation of the given data are as follows,

Probability of next customer paying cash =  [tex]\frac{a}{(a+b+c)}[/tex]

By putting the value, we get

Probability = [tex]\frac{35}{(35 + 13 + 5)}[/tex]

= [tex]\frac{35}{53}[/tex]

[tex]34in^2[/tex]

Step-by-step explanation:

First, you should find the area of the trapezoid which the formula for that is:

[tex](b1 + b2)h/2[/tex]

So, you will ad up 7in and 3in, and you should get 10in.

Now multiply 10 in by the height which is 5in, so it will be 50in^2. Then you have to divide that by 2 turning it into 25in^2.

For the top part, it is basically a triangle so you just multiply 3 by 6, giving you 18/2 = 9in^2

Add the two together and you should get 34in^2

Answer:

n= 12

Step-by-step explanation:

27=15+n

step 1. simplify

27=n+15

step 2. flip the equation n+15=27

step 3. subtract 15 from both sides

n=12

Answer:

12.

Step-by-step explanation:

We don't have the other number, so we must do the reverse operation, which is subtraction. So we have to subtract 27 from 15. 7-5 is 2, and 20-10 is 10. Add those together and you get 12.

You need to calculate the circumference of this wheel to determine how far it travels with each revolution.

First, you need to know the diameter of a circle, which is the length of a straight line drawn through the circle.

The magic number here is pi, which is roughly 3.14159265. The digits to the right of the decimal point continue infinitely.

Dividing a circle’s circumference by pi will give you a circle’s diameter.

Multiplying a circle’s diameter by pi will give you a circle’s circumference.

Step-by-step explanation:

Answer:

They are both identical cubes which makes it much easier.

Work out the volume for just one first.

The formula for volume is:

l x w x h

However, since it is a cube, all lengths are the same.

3 x 3 x 3 = 27

Now multiply it by 2 to get the volume of both combined:

27 x 2 = 54.

In short, your answer is  54cm 3

10 secs for Jane and Dien is 15 secs

Step-by-step explanation:

Using the together rate, it is found that Jane can eat a pizza in 10 seconds and Dien in 15 seconds.

It is the sum of each separate rate.

In this problem, the rates are:

Hence:

[tex]\frac{1}{x + 5} + \frac{1}{x} = \frac{1}{6}[/tex]

[tex]\frac{x + x + 5}{x(x+5)} = \frac{1}{6}[/tex]

[tex]\frac{2x + 5}{x^2 + 5x} = \frac{1}{6}[/tex]

[tex]x^2 - 7x - 30 = 0[/tex]

[tex](x - 10)(x + 3) = 0[/tex]

The positive solution is x = 10, hence Jane can eat a pizza in 10 seconds and Dien in 15 seconds.
