4 yards by 7 yards. 2 multiplied by 14 is 28, and 4 multiplied by 7 is also 28.

### A rectangle has an area of 96 sq ft if the width of the yard is 4 ft less than the length, what is the perimeter in ft of the yard?

The area of a rectangle is obtained through the equation,

A = L x W

The width of the yard is 4 ft less than the length and may be expressed as L - 4. Length may be solved through the following steps,

A = (L)(L-4)   ; 96 = L(L - 4)    ; L = 12 ft

The length and width are 12 ft and 8 ft, respectively. Perimeter may be solved through the equation,

P = 2 x (L + W)

Substituting the values of L and W

P = 2 x ( 12 ft + 8 ft) = 40 ft

Therefore, the perimeter of the yard is 40 ft.

### An architect plans to make a drawing of the room of a house. The segment LM represents the ceiling of the room. He wants to construct a line passing through Q and perpendicular to side LM to represent a wall of the room. He uses a straightedge and compass to complete some steps of the construction as shown..

Here are the steps

1: Put the compass on Q and make the width equal to the distance from Q to L. Extend line LM towards the left side of L and draw an arc hitting the line segment on the left side of L

2.  Without changing the width and position of the compass, draw an arc between L and M.

3. Without changing the width of the compass, put the compass on the point of intersection of the arc and line LM (left side of L). Draw an arc above line LM.

4. Without changing the width of the compass, put the compass on the point of intersection of the arc and line LM (right side of L). Draw an arc above line LM.

5. Use a straight edge to make a line from the intersection of the two arcs above line LM to Q intersecting through L along the way.

Using the given equations to solve:

2x + 7y = 4
-4x - 3y = 14

Expressing one equation in terms of x:

2x + 7y = 4
2x = 4 - 7y
x = (4 - 7y)/2

Substituting to the other equation:

-4 [(4 - 7y)/2] - 3y = 14
-8 + 14y - 3y = 14
11y = 22
y = 2

Substituting back to the first equation:

2x + 7(2) = 4
2x + 14 = 4
2x = -10
x = -5

Therefore, (x,y) = (-5 , 2)

### Dylan is 9 years older than Parry. Together their ages sum to 65 years. How old is Parry? a. 28 b. 37 c. 56 d. 45

When figuring out this type of question, we work backwards.

So, let's say that d= Dylan's age, p= Parry's age and s= the sum of their ages.

So d= p+9 and p+d=65.

When we write this as an expression, we get p + (p+9) =65.

We need to work out what p is!

First, let's take away 9 from 65. We get 56.

Now we know that Dylan and Parry's age is 56 divided by 2, because there are two of them. We know this because Dylan is 9 years older than Parry, and when we minus this 9, their ages are equal!

So, now it is a simple matter of dividing 56 by 2. This equals 28! Is this Parry's age?

To be sure, let's subsititue the factors we found into our equation: p + (p+9) =65.

So, 28 + (28+9) =56

To simplify, 28 + 37 = 65.

Everything checks out! Parry's age is 28 years!

### If the altitude of an equilateral triangle is 10, what is the length of each side?

All the angles of an equilateral triangle measures 60 degrees. The altitude measuring 10 is a side of the right triangle opposite to the angle. The side of the equilateral triangle becomes the hypotenuse to the right triangle generated by drawing the altitude. To get the measure of the hypotenuse, multiply the altitude to the sine of 60 degrees. The operation gives an answer of 8.66.

Thus, the length of each side of the equilateral triangle measures approximately 8.66 units.

### Sonia rolls a six sided number cube 12 times and records of she rolls a 2. What is the number of trials for this binomial experiment?

Answer:

12

Step-by-step explanation:

Binomial expression:

Where n = No. of trials i.e. no. of times experiment occur

p= Probability of success

q= Probability of Failure

r= No. of success.

We are given that Sonia rolls a six sided number cube 12 times and records of she rolls a 2.

Since here the cube was rolled 12 times.

Thus n =12

So, No. of trials =12

Hence the number of trials for this binomial experiment is 12.

Answer: D. (-14, -54)
WORKINGS
According to Table 1: y = 4x + 2 … (Equation I)
According to Table 2: y = 3x – 12 … (Equation II)
Substitute the value of y in equation I (4x + 2) for y in Equation II to solve for x
y = 3x – 12
4x + 2 = 3x – 12
4x – 3x = -12 – 2
x = -14
Substitute -14 for x in Equation I to solve for y
y = 4x + 2
y = 4(-14) + 2
y = -56 + 2
y = -54
Therefore, x= -14; y = -54

### Show and explain the theoretical probability of a player WINNING your probability game. for a spinner that has 8 sides (1-8) rules for the game so u know how to answer my question : Using a spinner and a coin. 2 players can play this game. So, the first person can spin the spinner and see where it lands on. The second person can start flipping the coin while the spinner is spinning, also see what sides it could land on ( HEADS or TAILS ). If the coin lands on heads, player 1 has a chance to gain or lose points in the round. If the coin lands on tails, player 2 has a chance. The player in focus then has 2 choices; they can flip the coin a second time or spin the spinner a second time. If they choose to flip a coin, they have to predict whether they think the coin will land on heads or tails. If they are correct, they gain the number of points showing on the spinner. If they are wrong, they lose that number of points. If they choose to re-spin the spinner, their goal is to beat the score of the first spin. If they do, they gain the difference in the points (for example: spin 1 lands on 2, spin 2 lands on 5; 5-2 = 3 points). If they spin a lower number, they lose the difference in points (example: spin 1 gets a 3, spin 2 gets a 1; 3-1 = 2 points lost) *If the spinner happens to land on the exact same number, the opponent gets 5 points. The first player to earn 40-points wins! BEST OF LUCK and have FUN !!! ^_~ !!!

You have a 1/2 chance of winning points on the flipping of the coin and a 36/64 chance of winning on the spinner. I got the coin because there's a half chance of guessing the side right and I got the spinner by drawing a two-way diagram.

### Which best describes the dimensions of a plane a.A plane has zero dimensions because it represents a location on the coordinate plane. b.A plane has one dimension because it is made up of an infinite number of points. c.A plane has two dimensions because it is a flat surface that has length and width but no depth. d.A plane has three dimensions because it is made up of exactly three noncollinear points.

Wellll, hold up there for just a second.

"A plane" is infinite.  Whatever direction you pick in "a plane",
the plane keeps going in that direction forever and never ends.
So "a plane" has NO dimensions.

Any PART of "a plane" has TWO dimensions, because any PART
of it that you pick occupies some length and some width.

A better way to say it is like this:

If you stick a nail into the plane at one point, THEN, to describe ANY
OTHER point in the plane relative to the nail, you need TWO NUMBERS.

THAT's why a line has one dimension, a plane has two, and a solid has
three dimensions ... it's how many numbers you need if you want to
send somebody to another point from where you're sitting.

Possible side lengths of a triangle are determined by the triangle inequality:
