Answer:

Step-by-step explanation:

BTW i'm probably wrong because my mom says i suck at math but friend me please lol

Answer:     1   19/24 ft

Step-by-step explanation: You multiply the fractions by the numbers needed to get the common denominator of 24 in this case 5/8 (put the two to the side for now.) multiply both top and bottom by 3 which will get you 15/24 then the whole number 2, your going to take it and subtract one from it so now there is only one whole number then with the one you subtracted you multiply (1x24)+15 *for the numerator* so now its 39/24 and for the second fraction 5/6 multiply both top and bottom by 4 now your fraction is 20/24 now...--> 39/24 - 20/24=19/24 and the left over whole number from the beginning goes down in front so the final answer is 1 19/24

Brad says that the literal equation a = 3b + 4c - a is solved for a. Do you agree yes or no?

Answers

Answer:

No

Step-by-step explanation:

The literal equation a = 3b + 4c - a contain "a" on the right side so it is not solved for a.

What is the equation?

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

If we solve any equation for x then

x = f(other than x)

For example

x + 2x + 3y = 4

Solve for x will be

3x + 3y = 4

x = (4 - 3y)/3 so on right-hand side no x term is present.

Given the equation,

a = 3b + 4c - a

The right-hand side has termed "a" so it is not solved for a.

Hence "The literal equation a = 3b + 4c - a contain "a" on the right side so it is not solved for a".

A right triangle has legs that measure 8 inches and 15 inches.
A. 5 in.
B. 7 in.
C. 17 in.
D. 23 in.

Answers

Answer:

C. 17

Step-by-step explanation:

I'm assuming you need the hypotenuse so to get that you do

The square root of a^2 + b^2

                            a squared + b squared

So it becomes square root of 8^2 + 15^2

                    =   square root of 64 + 225

                    =   square root of 289

                    =   17

Differentiate y=(sinx)(3x^2) please help please !

Answers

Answer:

6xsinx + 3x²cosx

Step-by-step explanation:

Differentiate using the product rule

Given y = f(x)(g(x) , then

[tex]\frac{dy}{dx}[/tex] = f(x)g'(x) + g(x)f'(x)

Here f(x) = sinx ⇒ f'(x) = cosx

g(x) = 3x² ⇒ g'(x) = 6x

Thus

[tex]\frac{dy}{dx}[/tex] = 6xsinx + 3x²cosx

Hey there! I'm happy to help!

From G to I is the total distance of the line (92). G to H is the first portion of the line (72) while H to I is the other portion.

To find H to I, simply subtract 72 from 92!

92-72=20

The distance from city H to city I is 20 miles.

please help me out, algebra 2 question #9

Answers

Answer :

Perimeter of rectangle = 26

Length is 7 less than 9 times the width.

We have to find the width of rectangle[tex].[/tex]

_________________________________

Let, width of rectangle be x therefore length of rectangle will be (9x - 7)

We know that, perimeter of rectangle is given by

perimeter = 2 (length + width)

⇒ perimeter = 2 (l + b)

⇒ 26 = 2 [(9x - 7) + x]

⇒ 13 = x + 9x - 7

⇒ 20 = 10x

x = 2 (width)

Cheers!

Step-by-step explanation:

Let breadth be x

As it is given that, the Length is 7 less than 9 times :

Therefore, Length will be 9x - 7

Perimeter of reactangle = 26

➳ 2 ( Length + Breadth) = 26

➳ 9x - 7 + x = 26/2

➳ 10x = 13 + 7

➳ 10x = 20

x = 2

Therefore,

Breadth = x = 2

Length = 9x - 7 = 9(2) - 7 = 11

A cube has a volume of 216 cubic inches. What is the length of each edge of the cube?

Answers

Volume of a cube = (edge)^3

In this problem,

Volume = 216in^2

Edge = ?

Let's plug our values into the formula above.

216in^3 = (edge)^3

Take the cbrt of both sides.

6in = edge

The length of each edge = 6in

Answer:

[tex]\boxed {\tt 6 \ centimeters}[/tex]

Step-by-step explanation:

The volume of a cube can be found using the following formula:

[tex]v=s^3[/tex]

where [tex]s[/tex] is the side length, or edge.

We know the volume is 216 cubic inches. We can substitute 216 cm³ in for [tex]v[/tex], the volume.

[tex]216 \ cm^3 = s^3[/tex]

We want to find the side length. Therefore, we must isolate the variable, [tex]s[/tex].

s is being cubed. The inverse of a cube is the cube root. Take the cube root of both sides of the equation.

[tex]\sqrt[3]{216 \ cm^3} =\sqrt[3]{s^3}[/tex]

[tex]\sqrt[3]{216 \ cm^3} =s[/tex]

[tex]6 \ cm=s[/tex]

The length of each edge of the cube is 6 centimeters.
