Twenty-two hundredths as a decimal is 0.22

A decimal numeral system is the standard system for denoting integer and non-integer numbers. The way of denoting numbers in the decimal system is often referred to as decimal notation.

The given number is,

Twenty-two hundredths

In numeric notation it is given as,

Twenty-two is 22

So hundredth of 22 is given as twenty-two divided by 100.

or, 22/100

or, 22/100 =  11*2/2*50

or, 22/100 = 11/50

Dividing 11 by 50 we get,

22/100 = 0.22

Hence,Twenty-two hundredths as a decimal is given as 0.22

Use the slope formula:

m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

(x₁ , y₁) = (0 , -2)

(x₂ , y₂) = (2 , -3)

Plug in the corresponding numbers to the corresponding variables:

m = [tex]\frac{-3 - (-2)}{2 - 0}[/tex]

Simplify. Note that if there are two negative signs directly next to each other, it becomes a positive sign:

m = [tex]\frac{-3 + 2}{2 - 0}[/tex]

m = [tex]\frac{-1}{2}[/tex]

Your slope is [tex]- \frac{1}{2}[/tex].

Answer:

There is not solution!

Step-by-step explanation:

1.

Simplify  -2\times 3−2×3  to  -6−6.

-6=-3\times 2+2−6=−3×2+2

2.

Simplify  3\times 23×2  to  66.

-6=-6+2−6=−6+2

3.

Simplify  -6+2−6+2  to  -4−4.

-6=-4−6=−4

Answer:

x=-27

Step-by-step explanation:

We want to find x right, so everything that does not have x you can move to the other side. 5x=-5-65-65. So that should be your equation so far. Now we know that when there are two negatives it is a negative and you add so -5-65=-70-65=-135. So your equation now should be: 5x=-135. Now we can divide -135 with 5 which gives us... -27! There’s your answer. Hope this was correct!

"In which quadrant(s) is csc(x) positive?"

Answer:

C. Quadrants I and II

csc(x) is positive in quadrants I and II.

What is quadrant?

"For an acute angle x, [tex]csc(x)=\frac{1}{sin(x)}[/tex]"

For given question,

We know that the ASTC rule.

The abbreviation for 'all sin cos tan' rule in trigonometry.

According to this rule,

- All trigonometric functions are always positive in the first quadrant.

- sine and cosine functions are always in the second quadrant.

- tan and cot functions are always in the third quadrant.

- sec and cosec functions are always in the fourth quadrant.

Therefore, csc(x) is positive in quadrants I and II.

These points are all in the vertical plane shown in the diagram. Think of the plane as a flat sheet of paper that doesn't bend.

Only points L and K are outside of this plane. So if we listed {L, D, A, J} then that list of points isn't coplanar.

A, B, D, J points are all in the vertical plane shown. The plane as a flat sheet of paper that doesn't bend.

The points are not coplanar if there does not exist any plane that contains those points.

Only points are outside of this plane. So if we listed {L, D, A, J} then that list of points isn't coplanar.

Therefore a plane is formed by a line and one point outside of it.

Then, we need to select the last point in such a way that it lies outside of the plane generated by the first 3 points selected.

Thus, A, B, D, J

These points are all in the vertical plane shown. The plane as a flat sheet of paper that doesn't bend.

The dolphin is -8 feet below sea level

Step-by-step explanation:

Start a -3 feet below sea level. Then subtract the -9 from when the dolphin dives. Then add the +4 feet. And you'll get -8. Hope this helps:)

The dolphin’s final elevation relative to sea level will be -8 feet.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a dolphin is swimming 3 feet below sea level. It dives down 9 feet to catch some fish. Then the dolphin swims 4 feet up toward the surface with its catch.

The elevation of the Dolphin is:-

Elevation = -3 - 9 + 4

Elevation  = -8 feet

Therefore, the dolphin’s final elevation relative to sea level will be -8 feet.
