Answer:

7%

Step-by-step explanation:

(15/220) x 100 = 6. 8182 = 7%

to convert to percentage multiply by 100

To convert to the nearest whole number, look at the first number after the decimal. If it is greater or equal to 5, add 1 to the number after the decimal. 8 is greater than 5, so add one to 6

Answer:

$1.10

Step-by-step explanation:

The first two stickers cost $0.8. The thrird one will cost 75% of the cost of one sticker. To find the answer, you multiply 0.75 (0.75 is 75% as a decimal) by 0.4 to get 0.3. $0.3 plus $0.8 equals $1.10.

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

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:

The cost of the sweater would be $17.28

Answer: 4(-1)^3 (2)^2=4

So you would first substitute the x for -1

Then you would substitute the y for 2

Giving you- 4 (-1)^3 Times (2)^2 which would equal 4

Hope this helps :) Im learning this too in math lol

Answer: 0.714

Step-by-step explanation:

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:

6:3.6

Step-by-step explanation:

The hight of the photo=15

so,15=6

15 :- 2.5=6

9 divided by 2.6= 3.6

therefour, the answer will be 6:3.6

Answer:

A

Step-by-step explanation:

Answer:

26.67%

Step-by-step explanation:

In the Seventh grade Rachel read 15 books in the 8th grade she read 19 books what is the percent of change of books read

The formula for Percent change =

New value - Original value/Original value × 100

New value = 19 books

Original value = 15 books

= 19 - 15/15 × 100

= 4/15 × 100

= 26.67%

The percent change of book read= 26.67%

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:

2/5

Step-by-step explanation:

I assume you mean 7/5 - 1

In that case you would need to make 1 a fraction that has a common denominator with 7/5.

7/5 - 5/5 = 2/5

[tex]80\pi \frac{rad.}{sec.} [/tex]

Step-by-step explanation:

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.

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.

Answer:

3

Step-by-step explanation:

3x-3=2x

3x-2x=3

x=3

Answer:

x=3

Step-by-step explanation:

3x - 3 = 2x

-3x -3x

-3 = -x

The x cannot be a negative so you divide both sides by -1 and then the answer becomes x=3

Answer:

d if "in2" means /2

Step-by-step explanation:

3x-4=90-34

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
