A rectangle’s width is one-fourth of its length. Its area is 9 square units. The equation l(1/4l) = 9 can be used to find l, the

length of the rectangle.

I see no actual question, but I'm assuming that you want to find the dimensions of the rectangle.

In general, the area of a rectangle with width w and lengthl is

A = wl

In this case, we know that the width is one-fourth of its length, which means w = \frac{1}{4}l

If we plug this expression for w in the formula for the area, we get

A = wl = \dfrac{1}{4}l\cdot l = \dfrac{1}{4}l^2

We also know that the area is 9 squared units, so we have

9 = \dfrac{1}{4}l^2

If we multiply both sides by 4, we get

l^2 = 36

Consider the square root of both sides (we only accept the positive solution, since a negative length would make no sense:

l = \sqrt{36} = 6

So, the length is 6, and the width is one-fourth of 6, i.e.

\dfrac{1}{4} \cdot 6 = \dfrac{6}{4} = \dfrac{3}{2} = 1.5

In the triangle above, the measure of A is 66°, and the measure of B is 68°. What is the measure of C?
valentina_108 [34]

Answer:

46°

Step-by-step explanation:

Given that :

Angle, A = 66°

Angle B = 68°

The sum of angles in a triangle is given by :

A + B + C = 180° (sum if angles una triangle)

66° + 68° + C = 180°

134° + C = 180°

C = 180° - 134°

C = 46°

Hence, angle C is 46°

What is the arithmetic sequence of a1=228 n=28 sn=2982
Art [367]

Answer:

use the formula sn= n(a1+an)/2

Step-by-step explanation:

2982=28(228+an)/2

5964=28(228+an)

5964/28=228+an

213=228+an

an=-15(last term)

to find difference use formula

an = a+(n-1)d

-15=228+(28-1)d

-243=27d

d=-243/27

d=-9

arithmetic sequence  can be found be keep on subtracting 9 from 228

hence the arithmetic sequence is

228, 219, 210, 201, 192, 183, 174........-15
