What does x equal?

Answer:

6.98

Step-by-step explanation:

8.50x.76(the remainder of 100 after 24 is taken out) =6.46

8% of 6.46 is around 52 cents

6.46+.52=6.98

Derivative Functions

The derivative function gives the derivative of a function at each point in the domain of the original function for which the derivative is defined. We can formally define a derivative function as follows.

Definition:

let f be a function. The derivative function, denoted by f', is the function whose domain consists of those values of  x  such that the following limit exists:

[tex]f'(x)= \lim_\\ \ \\ \frac{f(x+h)-f(x)}{h} {h \to 0}[/tex]

Answer:

Answer:

17.5

Step-by-step explanation:

The ratio of "pure drug" to liquid is 35:150

Therefore to evaluate for 75 mls we get the ratio 75/2150 or simply 1/2

multiply 35 by the ratio 1/2

35/2=17.5

Answer:

[tex]y = \frac{8x + 6}{2}[/tex] = 4x + 3

Step-by-step explanation:

2y = 8x + 6

y = (8x + 6) / 2

y = 8x / 2 + 6 / 2

y = 4x + 3

Answer:

$27.60

Step-by-step explanation:

Step 1: Find 5 over 8 of 24

[tex]\frac{5}{8}[/tex] doughnuts were glazed. So the total is 24. Now we just have to find 5 over 8 of the total.

[tex]\frac{5}{8} \times 24[/tex]

Or

[tex]\frac{5}{8} \times \frac{24}{1}[/tex]

Cross divide 8 and 24

[tex]24\div 8 = 3\\\\\frac{5}{1} \times \frac{3}{1}[/tex]

So we are left with

[tex]5\times 3[/tex]

Remember, "1" doesn't change anything.

Simplify

[tex]5\times 3 = 15[/tex]

Therefore, the cost of the glazed doughnuts WITHOUT TAX is $15.

Step 2: Add the tax to the cost of the glazed doughnuts.

[tex]\$0.84[/tex]

To find the tax or sales tax, just multiply the sales tax (in decimal form, but it already is) to the total.

[tex]15\times \:0.84=12.60[/tex]

Now, add the result to the total.

[tex]12.60+15.00 = 27.60[/tex] (you don't have to add the zeros, but it still won't change anything)

Answer:

Is there a question?

Step-by-step explanation:

The Pythagorean theorem states that for any right triangle with legs of length “a” and “b” and a hypotenuse of length “c,” the lengths of the sides always satisfy the relationship, “a^2 + b^2 = c^2.” In other words, the sum of the squares of the lengths of the two legs of a triangle is equal to the square of its hypotenuse. The formula is alternatively written with the hypotenuse length isolated (i.e., c = Sqrt(a^2 + b^2).

This is the definition.

(i)To make 8 pancakes 250 ml milk is needed. So, to make 4 pancakes=

(250/8)×4=120 ml is needed!

(ii)To make 8 pancakes 5g butter is needed and to make 12 pancakes=

(5/8)×12=7.5 g butter is needed!

answer: 2w^3 - 9w^2 + 10w = 528

The dimensions of the dumpster will be 8 feet by 11 feet by 6 feet.

Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as

V = L x W x H

A dumpster in the shape of a rectangular prism has a volume of 528 cubic feet. The length of the dumpster is 5 feet less than twice the width w, and the height is 2 feet less than the width. Then the equation will be

L = 2W - 5          ...1

H = W - 2           ...2

Then the polynomial is given as,

V = L x W x H

528 = (2W - 5)(W - 2)W

528 = (2W² - 5W)(W - 2)

528 = 2W³ - 4W² - 5W² + 10W

0 = 2W³ - 9W² + 10W - 528

Factorize the equation, then we have

2W³ - 4W² - 5W² + 10W - 528 = 0

(W - 8)(4W + 7)² = 0

W = 8, 1.75i, and -1.75i

Then the length and height will be

L = 2 x 8 - 5

L = 11 feet

H = 8 - 2

H = 6 feet

The dimensions of the dumpster will be 8 feet by 11 feet by 6 feet.

Answer:

y = 10x - 6

Step-by-step explanation:

If we know the function is linear then we can use any two coordinate pairs to find the slope of the line.

Note that the first pair is (0, -6) and the last pair is (4, 34).  The 'run' is from x = 0 to x = 4, a 'run' of 4.  The 'rise' is from -6 to34, a 'rise' of 40.  Thus, the slope of this line is m = rise / run = 40/4 = 10.

Answer:

4, 144, 145 are not Pythagorean triplets

Step-by-step explanation:

According tp Pythagoras theorem,

Sum of squares of two sides must be equal to square of the third side.

By Pythagoras theorem,

24^2 + 144^2 = 145^2

576 + 20736 = 21025

           21312 ≠ 21025

Numbers 24, 144, 145 does not satisfy the Pythagoras theorem.

So, 24, 144, 145 are not Pythagorean triplets.

Hence, checked.

Answer:

141

Step-by-step explanation:

First, we choose two variables to represent the two unknown numbers, the number of hamburgers and the number of cheeseburgers.

Let x = number of hamburgers.

Let y = number of cheeseburgers.

Now we use the given information to write two equations using the variables we defined above.

"If a hamburger shop sold a combined total of 423 hamburgers and cheeseburgers"

x + y = 423

"the number of cheeseburgers sold was two

times the number of hamburgers sold"

y = 2x

We have a system of two equations.

x + y = 423

y = 2x

Since the second equation is already solved for y, we can easily use the substitution method. We substitute what y equals to (2x) for y in the first equation.

x + y = 423

x + 2x = 423

3x = 423

x = 141

Since we let x = number of hamburgers, we have the answer.
