the width of a rectangle is three fourths of the length. The perimeter of the rectangle becomes 50cm when the length and width are increased by 2cm. Find the length and the width.

Answers

Answer 1

Answer: remember
P=2(l+w)
w=wdith
l=legnth
w is 3/4 legnth
w=3/4l

P=50 when l+2 and w+2

so
50=P=2(l+2+w+2)
w=3/4l, so sub
50=2(l+2+3/4l+2)
divide everybody by 2 to ge rid of nasty parenthasees
25=l+2+3/4l+2
25=1 and 3/4l+4
minus 4
21=1 and 3/4l
21=7/4l
times 4 both sides
84=7l
divide by 7
12=l
sub
w=3/4l
w=3/4(12)
w=9

legnth=9
width=12

Answer 2

Answer: then length=12
Width=3/4 of x
= 3/4 * 12
= 9
the answer is 9

Answers

So, all we have to do for this is
1. Turn the percent into a decimal. 25%=0.25
2. Divide the whole number by the percent. 35/0.25=140

The answer is 140

How do I figure out what 5550/1000

Answers

I'm guessing you want a mixed number.

To find this, find out how many times 1000 goes into 5550.
It goes in it evenly 5 times.

Now find what's left over.
5 x 1000 = 5000
5550 - 5000 = 550

Use 5 as the whole number, 550 as the numerator, and keep the denominator the same, which is 1000.

Now, the fraction in 5 550/1000 can be reduced.
50 goes into both.

550/50 = 11
1000/50 = 20

So the fraction is reduced to 11/20.

Your fraction is 5 11/20.

Now, if you were looking for a decimal, simply refer to the fraction.
Obviously, the whole number is 5.

To make life easier, multiply 20 to 100.
20 x 5 = 100.

Now we know the numbers to the right of the decimal will have two places.

Multiply 11 to 5.
11 x 5 = 55.

So, .55

Your final answer is 5.55

Fraction: 5 11/20
Decimal: 5.55

just do 5550/1000
You get 555/100 simplified
then divide and get 5.55
5.55 is your answer or just 5 11/20

explain why the sine of x is the sample regardless of which triangle is used to find it in the figure

Answers

Sine of x is used when to find the side of the triangle that does not have any right angle or is not a right triangle. This is according to the Law of Sines, which states that the sides of the triangle are to one another in the ratio as the sines of their opposite angles.

Lim
θ→0 (cos 9θ − 1)/(sin 8θ)

Answers

lim as θ → 0 of (cos 9θ - 1)/sin 8θ = lim as θ → 0 of (-9sin 9θ) / 8cos 8θ = 0/8 = 0

$\lim_(t \to 0) (cos 9 t - 1)/(sin 8 t) = (1-1)/(0)= (0)/(0)$
We can use the L`Hospitals rule:
$\lim_(t \to 0) (cos 9 t - 1)/(sin 8 t)= \n =\lim_(t \to 0) (-9 * sin 9 t)/(8 * cos 8 t)= (0)/(8)= 0$
