A rectangle has an area of 315 cm² . If the length is increased by 2 cm and the width is
decreased by 2 cm, the area would decrease by 21 cm² Find the dimensions of the original
rectangle (Round your answer to 3 significant figures where necessary.)
Answers
Answer:
Let the breadth be x and the length be y .
Original area =x.y
Now
length=y+2
breadth=x-2
Area=x.y-28 or x-2 × y+2
xy-28=(x-2)(y+2)
xy-28=xy+2x-2y-4
2y-2x=24
y-x=12
y=12+x
length=y-1
breadth=x+2
Area=xy+33 or (x+2)(y-1)
xy+33=(x+2)(y-1)
xy+33=xy-x+2y-2
35=2y-x
2y=35+x
y=(35+x)÷2
12+x=(35+x)÷2
24+2x=35+x
x=35-24
x=11
y=23
Therefore length is 23cm and breadth is 11cm

HELP One angle of a regular hexagon measures (2x+10)°Find x
Answers
Answer:
x = 55
Step-by-step explanation:
total number of degrees in a 6-sided figure is (6-2)x180, which is 720°
720/6 = 120
Each angle of a hexagon measures 120°
2x+10 = 720
2x = 110
x = 55

What term can you add to 5/6x -4 to make it equivalent to 1/2x - 4?
First I see the constants (-4) are equal to each other, so I don’t need to add anything to them.
5/6x and 1/2x are different though, so I know I need to add something, let’s call it y, to 5/6x to make it equal 1/2x
To add fractions, they have to have the same denominator. 1/2x becomes 3/6x.
5/6x + y = 3/6x
Subtract 5/6x from both sides
y = -2/6x
-2/6x can be simplified to -1/3x, so -1/3x is the answer.

A population of llamas stranded on a desert island is decreasing due to a food shortage by 6% per year. If the population of llamas started out at 350, how many are left on the island 10 years later?
Answers
Answer:
189
Step-by-step explanation:
Given data
Initial population=350
Rate = 6%
TIme= 10 years
Let us apply the compounding expression
A=P(1-r)^t----------The negative sign is due to decreasing value
substitute
A= 350(1-0.06)^10
A=350(0.94)^10
A=350*0.5386
A=188.51
Hence the approximate population will be 189

Answer:
triangle = 8
Step-by-step explanation:
The right side can be factored so that you have ...
8 x 4 = (triangle x 7) - (triangle x 3)
8 x 4 = triangle x (7 - 3) . . . . use the distributive property
8 x 4 = triangle x 4 . . . . . . simplify
8 = triangle . . . . . . . . . . divide both sides by 4
