The Length Of A Rectangular-shaped Patio Is 3 Feet Shorter Than Four Times Its Width.A. Write An Equation

Answers

Answer 1

Answer:

A. A = 4x² – 3x

B. Dimension = 37 ft × 10 ft

Step-by-step explanation:

A. Writing an equation to represent the area of the patio.

From the question given above,

Length (L) = (4x – 3) ft

Width (W) = x ft

Area (A) =?

Area of a rectangle is given by:

Area (A) = Length (L) × Width (W)

A = L × W

A = (4x – 3)x

Clear bracket

A = 4x² – 3x

B. Determination of the dimensions of the patio.

Area (A) = 370 ft²

Dimensions =?

Next, we shall determine the width and length. This can be obtained as follow:

From (A) above,

A = 4x² – 3x .... (1)

A = 370 ....... (2)

Equating equation 1 and 2, we have

4x² – 3x = 370

Rearrange

4x² – 3x – 370 = 0

Solving by formula method:

4x² – 3x – 370 = 0

Coefficient of x² (a) = 4

Coefficient of x (b) = –3

Constant (c) = –370

x = –b ± √(b² – 4ac) / 2a

x = –(–3) ± √(–3² – (4×4×–370)) / 2×4

x = 3 ± √(9 + 5920) / 8

x = 3 ± √(5929) / 8

x = 3 ± 77 / 8

x = (3 + 77) / 8 or (3 – 77) / 8

x = 80/8 or –74/8

x = 10 or –37/4

Since measurement can not be negative, thus,

x = 10

Width (W) = x ft

x = 10

W = 10 ft

Length (L) = 4x – 3 ft

x = 10 ft

L = 4(10) – 3

L = 40 – 3

L = 37 ft

Finally, we shall determine the dimensions. This is illustrated below:

W = 10 ft

L = 37 ft

Dimension =?

Dimension = L × W

Dimension = 37 ft × 10 ft

A fundraiser was held to split the profits between the 9 baseball players. How much money was raised if each player earned $326? Construct a division equation to represent the situation. Make sure to identify and label your variable. Solve for the variable and describe your answer. Show your work and prove your solution to be correct.

Answers

Answer:

Part 1

The number of baseball players that are to split the profits = 9 baseball payers

The amount of money each player earned = $326

Let x represent the total amount of money raised, and given that each baseball player received equal amount of the profits we have the following division equation;

[tex]The \ division \ equation \ is , \dfrac{x}{9} = \$ \, 326[/tex]

Part 2

Solving for the variable, gives;

x = 9 × $ 326 = $2,934

The amount of profits from the fundraiser, x = $2,934

Part 3

The amount, A, each of the 9 players will earn from the profit of $2,934 raised in the fund raiser is given as follows;

A = $2,934/9 = $326

∴ The amount each of the 9 players will earn, A = $326, therefore the answer corresponds to the value in the question and is therefore, correct

E: 2 and 4 only.​

Answers

Answer:

  C: 2 and 3 only.

Step-by-step explanation:

We know the sum or difference of two odd numbers is even, eliminating choices (1) and (4).

The product of two odd numbers is odd, so (2) is one of the true statements.

__

Let x/y = k, where x and y are both odd. Then x = ky. If k is even, then x is even, a contradiction. So, k must be odd. The integer ratio of two odd numbers is odd, so (3) is one of the true statements.

Only statements (2) and (3) are true.

The order of Rotational symmetry is 2 (option B) for the given figure.

What is order of rotational symmetry?

It is basically the number of times we obtain the initial(or same) figure in a single rotation of 360°.

The rotational symmetry of a shape demonstrates that when an object is rotated on its axis, the form of the object examines the same. Many geometrical shapes emerge to be symmetrical when they exist rotated 180 degrees or with some angles, clockwise or anticlockwise. Some of the examples exist as squares, circles, hexagons, etc.

If we rotate the picture by 90°or 270°, then it wont match the initial figure.

If we rotate the picture by 180° from initial, it will match the figure.

If we further rotate it by 180°( full 360° completed) , it will again match.

Hence, it matches 2 times in a single rotation.

Therefore it has rotational symmetry of order 2.

A midpoint is a point that divides a given line into two equal halves.The answers to the questions are:

1. BC = 89

b. AB = 45

c. AC = 44

2. The coordinate of I is 2.5

3. J = 19

4. MQ = 32

5. NO = 13

6. NO = 23

b. MN = 25

A line segment can be divided into different fractions. Where the point that divides the line segment into equal parts is the midpoint. however, number line is a system that shows the location or positions of all directed numbers.

The given questions can be solved as follows:

1. Given that point A is between BC and AB = 4x -3, BC = 7x + 5, AC = 5x - 16

But,

BC = AB + AC

7x + 5 = (4x -3) + (5x - 16)

          = 9x - 19

7x + 5 = 9x - 19

19 + 5 = 9x - 7x

24 = 2x

x = [tex]\frac{24}{2}[/tex]

x = 12

So that;

a. BC = 7x + 5

         = 7(12) + 5

BC = 89

The value of BC is 89.

b. AB = 4x -3

         = 4(12) - 3

AB = 45

Thus AB has a value of 45.

c.  AC = 5x - 16

          = 5(12) -16

 AC = 44

The value of AC is 44.

2. Given that H is the mid point of GI, and G = 8, I = -3.

Then;

I = 2.5

The coordinate of I is 2.5

3. A midpoint is a point that divides a line segment in to two equal halves. Given that J is the midpoint of KL. KL = 38

J = [tex]\frac{KL}{2}[/tex]

  = [tex]\frac{38}{2}[/tex]

J = 19

The value of the midpoint J is 19.

4. It can be deduced from the conditions given in the question that:

  MQ = MN + NO + OP + PQ

          = 8 + 8 + 16      (NB: OP + PQ = 16)

MQ = 32

Thus, value of MQ is 32.

5. Since P is the mid point of NQ, and OP = 11, OQ = 35

 Then;

PQ  = OQ - OP

      = 35 - 11

PQ = 24

Since, PQ = NP =24

Then;

NO = NP - OP

      = 24 - 11

NO = 13

NO has a length of 13.

6. NO = 2y + 11, OP = 3y - 2, NP = 6y + 3 and MP = 64.

But,

NO + OP = NP

(2y + 11) + (3y - 2) = 6y + 3

5y + 9 = 6y + 3

9 - 3 = 6y - 5y

y = 6

So that;

a. NO = 2y + 11

          = 2(6) + 11

NO = 23

Here, the value of NO is 23.

b. MN = MP - NP

But,

NP = 6y + 3

     = 6(6) + 3

NP = 39

Then;

MN = 64 - 39

MN = 25

So that MN has a value of 25.
