To compute the perimeter of a rectangle, you add the length, l , and width, w , and double this sum.

This means you can find the perimeter of a rectangle by evaluating the expression 2 (1 + w ).
Use this expression to find the perimeter of a rectangle with length 30 and width 75.

Answer:

a

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 9 and h = 12 , then

A = [tex]\frac{1}{2}[/tex] × 9 × 12 = [tex]\frac{1}{2}[/tex] × 108 = 54 cm²

180 students in the enviormental club

There are 60 students in the Environmental club.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

There are 240 students in the seventh grade,

and 25% are in the Environmental Club.

That means,

students are in the Environmental Club,

= 240 x 25/100

= 60

Therefore, 60 students are in Environmental club.

Step-by-step explanation:

The standard deviation of T is equivalent to 5.

       [tex]$\sigma={\sqrt {\frac {\sum(x_{i}-{\mu})^{2}}{N}}}[/tex]

Given is that a factory process requires 3 steps to finish a product. The steps each have a mean completion time of A = 10 seconds and a standard deviation of O = 5 seconds. The time it takes to complete each step is independent from the other steps.

We can write that -

5 = √∑(x{i} - 10)²/√3

√∑(x{i} - 10)² = 5√3

(√∑(x{i} - 10)²)² = (5√3)²

∑(x{i} - 10)² = 25 x 3

∑(x{i} - 10)² = 75

Now, we can write that -

σ = √(75/3)

σ = √25

σ = 5

Therefore, the standard deviation of T is equivalent to 5.

Step-by-step explanation:

Attached are the two graphs where the blue line represents the axis of symmetry.

Answer:

x ≈ ±2.1407

Step-by-step explanation:

0.5(x⁴ - 9) + 15 = 0

Distribute the 0.5 across the parentheses.

0.5x⁴ - 4.5 + 15 = 0

Combine the constants.

0.5x⁴ + 10.5 = 0

Subtract 10.5 from both sides.

0.5x⁴ = -10.5

Divide both sides by 0.5.

x⁴ = 21

Take the fourth root of 21.

⁴√21 ≈ ±2.1407

x ≈ ±2.1407

Step-by-step explanation:

The sum of the exterior angles of any polygon is 360°

Add the given angles and solve for x

93 + 46+ 3x + 62 + 4x +47 = 360

7x + 248 = 360

7x = 360 –248

x = 16

Answer:

B

Step-by-step explanation:

Choose an x point. Then plug it in and see if you get the correct y.

For example, I chose an x point of -1. When x = -1, you can see that y = 4.

Plug it in to the equations, and you find that B is correct.

y (4) = [tex]x^{2}[/tex] (-1 x -1) - 2x ( 2 times -1) + 1

4 = 1 - (-2) + 1

4 = 1 + 2 + 1

4 = 4

Answer:

x=6.36

Step-by-step explanation:

In a right triangle where the angles are 45, 45 and 90, the hypotenuse is equal to [tex]\sqrt{2}[/tex] multiplied by the length of the legs. Knowing this, we can set up the following equation:

[tex]9=x\sqrt{2}[/tex]

Multiply both sides by [tex]\sqrt{2}[/tex]

[tex]9\sqrt{2} =x\sqrt{2}*\sqrt{2}\\9\sqrt{2} =2x[/tex]

Divide both sides by 2

[tex]\frac{9\sqrt{2}}{2}=\frac{2x}{2}\\\frac{9\sqrt{2}}{2}=x[/tex]

[tex]x=6.36[/tex] (this answer is approximate)

Therefore, x is equal to 6.36.
