Answer:

filled in dot on -2 and shade the rest to the right (see below)

Step-by-step explanation:

This can also be read as "x is equal to or greater than -2." The "alligator" mouth, aka the inequality sign, is "eating" the x, meaning it's greater than the -2.

First graph the -2. Because it's also equal to, the dot on the -2 is filled in.

The inequality also acts as an arrow. It's pointing to the right, so the rest of the number line to the right is shaded.

This arrow method works only when the variable is on the left side so that is read "x is greater/less than a number."

Find the Are of the Shaded Region

Answers

Area of 3/4 circle = 3/4 x π x r²
= 3/4 x 22/7 x 6²
= 84.86cm²

That should be the correct answer
Hope this helps!!

Answer:

≈ 84.8 cm²

Step-by-step explanation:

The area of the shaded region is calculated as

area of circle - area of unshaded sector

area of circle = πr² = π × 6² = 36π

unshaded area = area of circle × fraction of circle

                          = 36π × [tex]\frac{90}{360}[/tex] = 36π × [tex]\frac{1}{4}[/tex] = 9π

area of shaded region = 36π - 9π = 27π ≈ 84.8 cm² ( nearest tenth )

In PQR the measure of R=90, QR=61 feet and RP=90 find the measure of P to the nearest degree.

Answers

Answer:

<P = 56 degrees

Step-by-step explanation:

Given the following

m<R = 90 degrees

QR = 61feet = Adjacent

RP = 90 feet= Opposite

Required

tan<P = opp/adj

Tan<P = 90/61

<P = arc tan (90/61)

<P = arctan 1.4754

<P = 55.9

<P = 56 degrees to the nearest degree

The measure of the third side of the triangle will fall between 5 and 29.

What is the Triangle Inequality Theorem?

Triangle Inequality Theorem is that for two sides of a triangle, the third side cannot be equal to or greater than the third side's length.

From the Triangle Inequality Theorem,

The sum of the lengths of any two sides of a triangle must be greater than the third side, then the third side of this triangle must be strictly less than 29.

But we can't make the length of the third side too small, either.

If x is the length of the third side, then x + 12 > 17, which means that x > 5

Therefore, the length of the third side must fall between 5 and 29.

Hence, the measure of the third side of the triangle will fall between 5 and 29.

Answers

Answer:B

Step-by-step explanation:

The equivalent expression is 8.

Option B is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

[tex](16^{3/2})^{1/2}[/tex]

This can be written as,

= [tex]16^{3/2 \times 1/2}[/tex]

= [tex]16^{3/4}[/tex] ______(1)


Now,

16 = [tex]2^4[/tex] ______(2)

Now,

From (1) and (2),

= [tex]2^{4 \times 3/4}[/tex]

= 2³

= 8

Thus,

The equivalent expression is 8.
