Help me find the equation for the dimensions of a window, please!

Answers

On the sheet, it's not even asking you for the dimensions.
It's just asking you to set up the equation that you would use
to find the dimensions.  That's a great way to do it, because
nobody actually needs the answers, the whole thing is only
meant to help you learn HOW to find them.
==========================================
Call the width of the window 'W' .

We know that the length is 5 feet more than the width, so the length is (W + 5).

The area is (length times width).

Area = (W + 5) times (W).

36 = (W + 5) W

36 = W² + 5W

Subtract 36 from each side:

W² + 5W - 36 = 0

That's choice-4 .

Find the measure of b.

Answers

Answer:

b = 80°

Step-by-step explanation:

The inscribed angle measuring 100°, is supplementary to the angle opposite it in the inscribed quadrilateral.

Thus, the angle is = 80°

Therefore, b + 80° = 180° (angle on a straight line = 180°).

Thus, b = 180° - 80° = 100°.

The measure of b is 80°.

Which geometric series represents 0.4444... as a fraction?

Answers

Answer: It can be expressed as

(4)/(10)+(4)/(100)+(4)/(1000)+........

Step-by-step explanation:

Since we have given that 0.44444.......

We need  geometric series that represents as a fraction.

so, it can be written as

0.4+0.04+0.004+0.0004...............

But as we are required to write it as a fraction , So, it becomes,

(4)/(10)+(4)/(100)+(4)/(1000)+(4)/(10000)............

and it is a geometric series.

Because it has first term = a = (4)/(10)

and common ratio = r = (a_2)/(a_1)=((4)/(100))/((4)/(10))=(1)/(10)

Hence, it can be expressed as

(4)/(10)+(4)/(100)+(4)/(1000)+........
The geometric series that represents 0.4444... as a fraction is: 4/6 * [k=0, ∞]∑1/6^k 

Simplifying radicals: √196s²

Answers

√196s² = √196 times √s²

s² is the square of 's'
196 is the square of 14
So both can easily come out of the radical.

Your round-trip drive to school is 3 7/10 miles. How many miles do you drive to and from school in 5 days?

Answers

Answer:

In 5 days, you drive 18.5 miles to and from school.

Step-by-step explanation:

The question tells us that your round-trip drive to school is 3 7/10 miles, wich means that your round-trip drive to school is 3.7 miles, because

3+(7)/(10)=(37)/(10)=3.7

Now, we just have to multiply 3.7 miles per round-trip drive, times 5 days of round-trip drive to and from school, and

3.7*5=(37)/(2)=18.5

This means that in 5 days, you drive 18.5 miles to and from school.
you multiply 3 7/10 by 5 and you get 18.5 turned in to a inproperfraction is 37/2 as a properfraction it is 18 1/2
