Answer:

[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+5=13

Step-by-step explanation:

if you want the answer, its 8

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.

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.

Answer:

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.

Answer: Length = 15 meters

Width = 2 meters

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

Area of a rectangle = l × w

where l = length

w = width

Therefore,

2l + 2w = 34 ...... i

l × w = 30 ........ ii

From equation i

2l + 2w = 34

Divide through by 2.

l + w = 17 ...... iii

Then, l = 17 - w ........ iv

Put equation iv into ii

l × w = 30

(17 - w) × w = 30

17w - w² = 30

w² - 17w + 30 = 0

w² - 15w - 2w + 30 = 0

w(w - 15) - 2(w - 15) = 0

(w - 2) = 0

w = 0 + 2 = 2

w - 15 = 0

w = 0 + 15 = 15

Length = 15 meters

Width = 2 meters

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:

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

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.
