Divide 252 by 21.
21 times 12 = 252
12 is 9 units shorter than 21.
so the answer is 12 inches by 21 inches
you work backwards from the area
area = width times length
a = wl
we know w is 9 units shorter than the length
so now we have the equation 252=(l-9) times l
plug in 21 for l and then solve there is your answer.

What is the predicted difference in sleep between individuals A and B, where individual A has 12 years of education and works 20
kari74 [83]

Answer: The predicted difference in sleep is 1251437 minutes.

Step-by-step explanation:

Since we have given that

Number of years of education = 12 years

Number of minutes a week = 2000

As we have

In case of individual A:

7 days = 2000 minutes

1 year = 365 days = \dfrac{2000}{7}\times 365=104285

12 years = 104285\times 12=1251420\ minutes

In case of individual B:

7 days = 3000 minutes

1 year = 365 days = \dfrac{3000}{7}\times 365=156428

16 years = 156428\times 16=2502857 minutes

So, the predicted difference in sleep between individuals A and B is given by

2502857-1251420\\\\=1251437\ minutes

Hence, the predicted difference in sleep is 1251437 minutes.

Rewrite 3x + 4y = 10 using function notation.
OleMash [197]
F(x) is a way of writing the output of a function, also known as the dependent variable. You are probably used to seeing y in this place, but all you're doing is replacing y with f(x).

3x+4y=10  \\ 4y=-3x+10  \\ y =  \frac{-3}{4}x+ \frac{5}{2}  \\  \\  f(x) = \frac{-3}{4}x+ \frac{5}{2}

To construct a regular octagon, what measure would be necessary for each interior angle? Construct an angle of that measure.
svp [43]

Answer:

135^\circ

Step-by-step explanation:

Given that, a <em>regular octagon </em>is to be constructed.

To find:

Each angle in the octagon = ?

Solution:

We know that a regular triangle (polygon with 3 sides) has an interior angle of 60^\circ.

And a regular quadrilateral (square) has an interior angle of 90^\circ.

Therefore, formula for interior angle of a regular polygon with n number of sides can be given as:

\dfrac{n-2}{n}\times 180^\circ

For an octagon, we have n=8.

Value of Interior angle in a regular octagon:

\dfrac{8-2}{8}\times 180^\circ=\dfrac{6}{8}\times 180^\circ=\bold{135^\circ}

Kindly refer to the attached image for the angle of 135^\circ
