The solution of the expression is,

⇒ 85.72

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ 600 divided by 7

Now, We can divide the numbers as;

⇒ 600 divided by 7

⇒ 600 ÷ 7

⇒ 85.72

Answer:

The equation of the perpendicular line:

2x + 5y = ╼ 15

Answer:

b= -4

Step-by-step explanation:

On both sides of the equation has distributive property. We need to solve that first. Let's start with the left side of the equation.

*Positive multiplied by a negative equals a negative

-2b+2(b-10)= 2(10+5b)

-2b+2b-20= 2(10+5b)

-20= 2(10+5b)

Now let's solve the right side of the equation

-20= 20+10b

-20  -20

-40 = 10b

-40/10 = 10b/10

b= -4

Answer: Area of the rectangular room = length x Breadth

Length= 18 and Breadth = 12

Therefore the Area required to cover the floor = 18 * 12 = 216 ft2

The area of the rectangular room is given by the equation A = 216 feet²

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the equation will be

The length of the rectangular room = 18 feet

The width of the rectangular room = 12 feet

Area of Rectangle = Length x Width

Substituting the values in the equation , we get

Area of the rectangular room = 18 feet x 12 feet

On simplifying the equation , we get

Area of the rectangular room A = 216 feet²

Therefore , the value of A is 216 feet²

Hence , the area of the rectangular room is 216 feet²

Answer:

The derivative (or gradient function) describes the gradient of a curve at any point on the curve. Similarly, it also describes the gradient of a tangent to a curve at any point on the curve.

To determine the equation of a tangent to a curve:

Find the derivative using the rules of differentiation.

Substitute the \(x\)-coordinate of the given point into the derivative to calculate the gradient of the tangent.

Substitute the gradient of the tangent and the coordinates of the given point into an appropriate form of the straight line equation.

Make \(y\) the subject of the formula.

The normal to a curve is the line perpendicular to the tangent to the curve at a given point

Answer:

[tex]\frac{3x+7}{x+2}[/tex]

Step-by-step explanation:

Given the following question:

[tex]\frac{(x+4)(3x+7)}{(x+4)(x+2) }[/tex]

In order to simplify the expression given we can only cancel the common factor which is four.

[tex]\frac{(x+4)(3x+7)}{(x+4)(x+2) }[/tex]
[tex]cf=(x+4)[/tex]
[tex]\frac{x+4}{x+4}[/tex]
[tex]=\frac{3x+7}{x+2}[/tex]

Cannot be simplified further due to it not having any more common factors. Your answer is "3x + 7 / x + 2."

Hope this helps.

Answer:

( 3x+7 ) / ( x+2 )

Step-by-step explanation:

\frac{(x+4)(3x+7)}{(x+4)(x+2)}

When you set up the equation like a fraction, you can now cancel out like terms. (x+4) is in the denominator- as well as the numerator. They are the same in parentheses. So you can cancel. Once that's done, you'll be left with

\frac{3x+7}{x+2}

You cant simplify any further because there are no more (like groups) aka (common factors)

( 3x+7 ) / ( x+2 )

Step-by-step explanation:

pls rate five stars, thanks  :)

Step-by-step explanation:

a) Tangent equals sine divided by cosine.  Therefore:

tan(-t) = sin(-t) / cos(-t)

b) Using the fact that sin(-t) = -sin(t) and cos(-t) = cos(t):

tan(-t) = -sin(t) / cos(t)

tan(-t) = -tan(t)

c) A function is symmetric about the origin if f(-x) = -f(x) (in other words, if it's an odd function).  Therefore, y = tan(t) is symmetric about the origin.

Answer:

75% chance

Step-by-step explanation:

Probability always adds to 1.00

Letter grades are always in the form A, B, C, D...

The grades above a C are A, which is a 25% chance and B, which has a 50% chance. Adding these up we get a 75% chance.

#LearnWithBrainly

The probability of getting a grade above a C is 0.75, or 75%.

We have,

To calculate the probability of getting a grade above a C, you need to add the probabilities of getting an A or a B.

Given:

Probability of getting an A (P(A)) = 0.25

Probability of getting a B (P(B)) = 0.50

A grade above a C includes grades of A and B.

Therefore, the probability of getting a grade above a C (P(above C)) is:

P(above C) = P(A) + P(B)

P(above C) = 0.25 + 0.50

P(above C) = 0.75

Thus,

The probability of getting a grade above a C is 0.75, or 75%.
