The area of the rectangular room would be 84 square meters.

The area of a rectangle is defined as the product of the length and width.

The area of a rectangle = L × W

Where W is the width of the rectangle and L is the length of the rectangle

A rectangular room that is 9 3/5 meters long and 8 3/4 meters wide

According to the given question, we can write the dimension as:

The width of the room = 8 3/4 meters = 35/4 meters

The length of the room = 9 3/5 meters = 48/5 meters

The area of the room = width of the room ×  length of the room

The area of the room = 35/4 × 48/5

Apply the multiplication operation,

The area of the room = 84 square meters

Therefore, the area of the room is 84 square meters.

=============================================================

Explanation:

I recommend drawing out the number line. Plot -16 and 14 on it.

Either count out the spaces, or subtract and apply absolute value, to find the distance from -16 to 14 is exactly 30 spaces.

----------

Or you can think of it like this:

From -16 to 0 is 16 spaces

From 0 to 14 is another 14 spaces

That's 16+14 = 30 spaces total.

----------

In short, segment CD is 30 units long.

Point E is somewhere on segment CD.

x = distance from E to C

y = distance from E to D

x+y = EC+ED = CD = 30

x+y = 30

y = 30-x

We're told the distance from E to C is 1/4 the distance from E to D, so,

x = (1/4)*y

x = (1/4)*(30-x)

x = 0.25*(30-x)

x = 7.5 - 0.25x

x+0.25x = 7.5

1.25x = 7.5

x = (7.5)/(1.25)

x = 6

The distance from E to C is 6 units.

This means we'll add 6 units to the location of point C to find out where to place E

E = C+6 = -16+6 = -10 is the final answer

♡ Answer ♡

G) 1/12

♡ Step-by-step explanation ♡

  In order to figure out this problem, we have to take a few relatively simple steps.

  First, we must count the total number of coins in the cash register. Do not change the value of these coins. Simply take the numbers listed in the problem and add them up. Your process for completing this step should look something like this: 10+11+13+6 equals 40. With this being said, there are 40 coins in the cash register.

  Next, we must remember the values of the two coins the question is asking for: pennies and dimes. Keep in mind that, out of all 40 coins, 10 of them are pennies and 13 of them are dimes.

  Then, we write the fractions used to find the answer to this problem. In the question, the cashier (hypothetically) draws a penny first, and then a dime. This means a penny is drawn before a dime is drawn. (Although it seems like a miniscule detail, this knowledge is actually something extremely important to remember. This small piece of information can actually change the entire answer if not used properly.)

  In this problem, the cashier would choose a single penny out of the 10 in contrast to the total 40 coins. Since there are 10 pennies overall, and 40 coins overall, the probability of choosing a penny first is 10/40.

  After we complete the probability of choosing a penny before all else, we must find the probability of choosing a dime after choosing a penny. Since the dime will be chosen after the penny is chosen, one coin will be gone: the chosen penny. So, the total amount of coins within the cash register changes (or more specifically decreases (by 1)) from 40 to 39. However, the amount of dimes, 13, stays the same. With this information in mind, we can write a fraction of 13/39 for the probability of choosing a dime after choosing a penny.

  Finally, now that we have both probability fractions, we can figure out the answer to the question. In order to do this, we multiply and simplify both fractions. 10/40*13/39 is 130/1560. 130 ÷ 130 is 1. 1560 ÷ 130 is 12. 1 ÷ 12 can also be written as 1/12. Therefore, the answer to this problem is G) 1/12.

(The paragraph and author's note below are technically optional thought processes and information, but read them if you wish. Although I would recommend reading further, considering another way to solve the question is mentioned, it is entirely you (the reader's) choice.)

  You can also check this answer through the other/alternate way of solving this problem: by simplifying both probability fractions before you multiply them. 10/40 can be simplified to 1/4. 13/39 can be simplified to 1/3. After doing this, we multiply both simplified probability fractions in order to find, or in this case check, the answer. 1/4*1/3 is 1/12. 1/12 is the same fraction as the one present in choice G. This is the same answer as the one we previously got. This enforces the idea that G) 1/12 is indeed the answer to this question.

  A/N (Author's Note): Although it took quite a while to jot down, this was truly a blast to write and explain! I hope this helped those that needed/wanted it. Have a wonderful week reader(s)!

a) Another name for plane Z is LN plane.

b) PHJ and M are distinct points that are collinear.

c) N and K are distinct points that are coplanar.

d) HL and HK are distinct lines that intersect

a) The common point in lines LN and PN  is N and it is the intersection point.

b) Any three non-collinear locations inside a plane can be used to give it a name. Points H, J, and K cannot be combined because an unlimited number of planes cross through them. Think about the flat piece of paper rotating about this axis (like a propeller). We can only build one specific plane if the points are not all along the same line.

I'll choose P, H, and J as the non-collinear points to give the object the name Plane PHJ. There may be other solutions.

c) Because they are on the same line, points H, J, and K are collinear. Fill up the answer box by selecting either H or K. I'll choose point K.

d) Line HK and point P are parallel. Both of them are present on the same flat piece of paper or on the same flat plane.

That flat plane can be compared to the surface of the earth, but point N is located underneath. Therefore, the ground plane and point N wouldn't be coplanar.

Answer:

0.857 miles in 1 hour

Step-by-step explanation:

It is given that,

A crew of highway workers paved 12 mile in 14 hour.

We need to find how much will they pave in 1 hour if they work at the same rate.

14 hours = 12 miles

To find how much they pave in 1 hour, we must divide 12 by 14 as follows :

[tex]1\ \text{hour}=\dfrac{12}{14}\ \text{miles}\\\\=0.857\ \text{miles}[/tex]

Hence, they pave 0.857 miles in 1 hour.0.857 miles in 1 hour.

Answer:

Oy=2x+3

Step-by-step explanation:

The function that has the {y} - intercept as that of the function graphed is y = 2x + 3

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is to find the linear function that has the same y-intercept as the one that is represented by the graph.

The function graphed has the {y} - intercept of 3.

For the functions given -

Functions              {y} - intercept

y=2x-4                        -4

y=2x-3.                       -3

y=2x+3                        3

y=2x+4                        4

So, the function that has the {y} - intercept of 3 is y = 2x + 3.

Therefore, the function that has the {y} - intercept as that of the function graphed is y = 2x + 3.

There will be 18 grams left after 12 hours.

Step-by-step explanation:

Half-life is the amount of time it take for a cell to turn from one condition to another.

To find the amount of grams for the first 6 hours.

72 ÷ 2= 36

Now, since 6 x 2 = 12, we need to divide 36 by 2 to find the next half-life.

36 ÷ 2 = 18

Therefore, there will be 18 grams left after 12 hours.

Answer:

m<4 = 44°

Step-by-step explanation:

m<8 = 34°

m<9 = 40°

m<3 = 62°

m<2 = 34° + 40° (exterior angle theorem of a triangle)

m<2 = 74°

m<3 + m<4 + m<2 = 180° (sum of ∆)

62° + m<4 + 74° = 180° (substitution)

m<4 + 136° = 180°

m<4 = 180 - 136 (substitution property of equality)

m<4 = 44°

The equation that models her distance from home, y, as a function of time, x will be:

Step-by-step explanation:

We know that the slope-intercept form of a linear function is

y = mx+b

Here m is the slope and b is the y-intercept

Given that Aniyah is driving home at a constant speed.

at t = 20 minutes, she has covered 70 miles

so the rate of change = 70/20

                                     = 3.5 miles per minute

Finding the y-intercept by substituting m = rate of change = 3.5 and the point (20, 70)

y = mx+b

70 = 3.5(20) + b

b = 70 - 70

  = 0

Thus, the equation becomes

y = mx+b

y = 3.5x + 0

y = 3.5x

Therefore, the equation that models her distance from home, y, as a function of time, x will be:
