Answers

Answer 1

Isolate the absolute-value term:

2 |3x - 5| - 4 = 12

2 |3x - 5| = 8

|3x - 5| = 4


Recall the definition of absolute value:

[tex]|x| = \begin{cases}x & \text{if }x \ge0\\-x&\text{if }x<0\end{cases}[/tex]

We consider two cases:

• If 3x - 5 ≥ 0, then |3x - 5| = 3x - 5, and the equation resolves to

3x - 5 = 4

3x = 9

x = 3

• Otherwise, if 3x - 5 < 0, then |3x - 5| = -(3x - 5) = -3x + 5, hence

-3x + 5 = 4

-3x = -1

x = 1/3

Find the area of a circle with a diameter of 16.
Either enter an exact answer in terms of piπpi or use 3.14 for piπpi and enter your answer as a decimal.

Answers

Answer:

64π or 200.96

Step-by-step explanation:

The area of a circle is [tex]\pi r^2[/tex]. The radius of the circle is half the diameter, which is 16/2 = 8. The area of the circle is 64π.

Answer:

64π = area
200.96 = area

Step-by-step explanation:

Diameter = radius * 2

16 = 2r

radius = 8

Radius^2 * π = area

8^2 * π = area

64π = area

64*3.14 = area

200.96 = area

The length of each side of an equilateral triangle is increased by 5 inches, so the perimeter is now 60 inches. Write and solve an equation to find the original length of each side of the equilateral triangle.

Answers

P=3a (perimeter = a+a+a) ( “a” is the length of each side)

60 = 3a

60/3 = a

20 = a
Each side is currently 20
Then you subtract 5 to get your original length

a = 20 - 5
a = 15
The original length of each side of the equilateral triangle is 15.

rectangular pyramid are shown in
the diagram. What is the volume
of the pyramid in cubic meters?

Answers

Answer:

8 cubic meters

Step-by-step explanation:

Formula for the volume of a rectangular pyramid:

[tex]V=\frac{lwh}{3}[/tex]

Take note

[tex]l=[/tex] base length

[tex]w=[/tex] base width

[tex]h=[/tex] pyramid height

We are given [tex]l[/tex], [tex]w[/tex], and [tex]h[/tex].

Lets solve for [tex]V[/tex]

[tex]l=3[/tex]

[tex]w=2[/tex]

[tex]h=4[/tex]

Now plug in our numbers into the formula:

[tex]V=\frac{3*2*4}{3}[/tex]

Evaluate the numerator

[tex]3*2*4=24[/tex]

Then we have

[tex]V=\frac{24}{3}[/tex]

Simplify and we get:

The division is one of the four fundamental arithmetic operations. The filling that Camilo uses in each tray is 10.667 ounces.

What is Division?

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

The total filling that was available with Camilo is 32 ounces, which he put in three different trays equally. Therefore, the filling available in each tray is equal to,

[tex]\rm \text{Filling in each tray} = \dfrac{\text{Total Filling}}{\text{Number of tray}}\\\\\text{Filling in each tray} = \dfrac{32\ ounces}{3} = 10.667 ounces[/tex]

Hence, the filling that Camilo uses in each tray is 10.667 ounces.

one side of a rectangle is 7 inches longer than another side. If the longer side of this rectangle decreases by 3 inches, and the shorter side increased by 2 inches, the area of the new rectangle equals the area of the original rectangle. Find the dimensions of the original rectangle.

Answers

Answer:

The length is 15 and the width is 8

Step-by-step explanation:

Use this formula to find what the dimensions are. x is the length of the shorter side while (x+7) is the length of the longer side:

(x+7)(x) = ((x+7)-3)(x+2)

x = 8

(8+7)(8) = ((8+7)-3)(8+2)
15(8) = (15-3)(10)
120 = 12(10)
120 = 120

The length is proved 15 and the width is proved 8.

A square is circumscribed about a circle with a diameter of 10 cm. What is the correct set up to find the area of the shaded region?

Answers

Answer:

21.5 cm² (nearest tenth)

Step-by-step explanation:

FormulaeArea of a square = x² (where x is the side length)Area of a circle = πr²  (where r is the radius)Radius = 1/2 diameter

Solution

To find the shaded region, subtract the area of the circle from the area of the square.

Square

Area of the square = 10² = 100 cm²

Circle

Given diameter of circle = 10 cm

⇒ radius = 10 ÷ 2 = 5 cm

⇒ Area of the circle = π · 5² = 25π cm²

Area of shaded region

= area of square - area of circle

= 100 - 25π

= 21.46018366...

= 21.5 cm² (nearest tenth)

Answer:

[tex]A_{total} = 217\ cm^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the bottom rectangle

[tex]A = l * w[/tex]

[tex]A = 14\ cm * 11\ cm[/tex]

[tex]A = 154\ cm^2[/tex]

Step 2:  Determine the area of the top rectangle

[tex]A = l * w[/tex]

[tex]A = 7\ cm * (20\ cm - 11\ cm)[/tex]

[tex]A = 7\ cm * 9\ cm[/tex]

[tex]A = 63\ cm^2[/tex]

Step 3:  Determine the total area

[tex]A_{total} = 154\ cm^2 + 63\ cm^2[/tex]

[tex]A_{total} = 217\ cm^2[/tex]

Answer:  [tex]A_{total} = 217\ cm^2[/tex]

The number a is less than the number b by 1/5 of b. By what part of a is b greater than a?

Answers

Answer:

b is greater than a by 1/4 of a

Step-by-step explanation:

The statement “The number a is less than the number b by 1/5 of b”

means “if we subtract one fifth of b from b itself we get a”

we write this mathematically like this :

[tex]a=b-\frac{b}{5}[/tex]

_________

[tex]\rightarrow a = \frac{5b-b}{5} =\frac{4b}{5}[/tex]

[tex]a=\frac{4b}{5} \Longrightarrow 5a=4b[/tex]

[tex]5a=4b\Longrightarrow b=\frac{5a}{4}[/tex]

[tex]\Longrightarrow b=\frac{5a}{4} =\frac{4a+a}{4}=\frac{4a}{4}+\frac{a}{4}=a+\frac{a}{4}[/tex]

What is the perimeter of a shape?

Answers

Perimeter is the combined ammount of all the sides added together.

For example, if a square has sides of 4, it would be 16 because 4+4+4+4 = 16 units.

Answer:

Perimeter is the total distance around the outside of a shape.

Step-by-step explanation:

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications. A calculated perimeter is the length of fence required to surround a yard or garden. The perimeter of a wheel/circle (its circumference) describes how far it will roll in one revolution. Similarly, the amount of string wound around a spool is related to the spool's perimeter; if the length of the string was exact, it would equal the perimeter.
