Step-by-step explanation:
A retangle has an area of 30 square meters and a perimeter of 34 meters what are the dimensions of the retangle
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
solve : 3x - 3 = 2x
if you can show workings that would be great thank you !
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

if you buy three stickers you get a 75% discount on third sticker if one sticker cost $.40 how much will three stickers cost you
Answer:

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.

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
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%

A tire has a radius of 7.5 inches.
How many inches will the tire travel after one rotation?
Answer:
80
[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.

Suppose 15 Argus student ride the city bus to school. Out of a total of 220 students, what percent ride the city bus (round to nearest whole %)
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

27=15+n I can not get this one ether
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+ 15 - 15 = 27 - 15 =
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:
sin2θ = - [tex]\frac{24}{25}[/tex]
Step-by-step explanation:
Given
cosθ = [tex]\frac{3}{5}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex] and in fourth quadrant
Then this is a 3- 4- 5 triangle with opposite side = 4
sinθ < 0 in fourth quadrant, then
sinθ = - [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{4}{5}[/tex]
Using the double angle identity for sine
sin2θ = 2sinθcosθ
= 2 × - [tex]\frac{4}{5}[/tex] × [tex]\frac{3}{5}[/tex] = - [tex]\frac{24}{25}[/tex]

the perimeter of the floor of a room is 18 metre and its height is 3 cm what is the area of 4 walls of the room
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.
