Answer:

15 hrs

Step-by-step explanation:

10 miles= 3hrs

50miles/10miles= 5

5(3hrs)=15 hrs

Answer:

10 miles = 3 hours

10 x 5 = 50

3 x 5 = 15

Bredt rode his bicy for 15 hours if he rode for 50 miles.

Answer:

B) [tex]x = \sqrt{60}[/tex]

Step-by-step explanation:

1. As you can see from the image, there are two right triangles in the isosceles triangle. The base of each right triangle is 2 (because 4 ÷ 2 = 2), and the hypotenuse is 8.

2. Let's use Pythagorean Theorem to find the height of each right triangle, which will also give us the height of the isosceles triangle: [tex]a^2 + b^2 = c^2[/tex], where a = height, b = base, and c= hypotenuse.

3. The√(60) is the height of each right triangle, and it's also the height of the isosceles triangle. Therefore, the answer is B) x = √60.

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.

Step-by-step explanation:

The x-intercepts of the parabola is where the quadratic is on the x-axis. According to the graph, we can see that the graph shows that the parabola touches the x-axis at 4 and 5.

∴ our answer is (5, 0) and (4, 0)

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: 4 hours

Step-by-step explanation: 15-5=10 10/2.50 =4

Answer:

4 hours

Step-by-step explanation:

$15 is our initial value, and we have a flat fee of $5

15-5=10

We have a remaining $10 left to be divided by the $2.50 per hour

10÷2.50=4

4 tells us the number of hours

It is a positive gradient therefore the answers cannot be negative. Since it is an increase of 4 dollars it is option D.

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.

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

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:

[tex]\boxed {\sf x=6}[/tex]

Step-by-step explanation:

[tex]\sf 5(x - 3) + 2 = 5(2x - 8) - 3[/tex]

Use the Distributive property :

[tex]\boxed { \sf Multiply\: 5\: by \:x\: and \:5\: by\: 3:}[/tex]

→ [tex]\sf 5x-15+2[/tex]

→ [tex]\sf -15+2[/tex]

[tex]\sf =-13[/tex]

[tex]\sf 5x-13[/tex]

______________________

[tex]\sf 5\left(2x-8\right)-3[/tex]

[tex]\boxed {\sf Multiply\: 5 \: by \: 2x \: and \: 5\: by\: -8:}[/tex]

→ [tex]\sf 10x-40-3[/tex]

→ [tex]\sf -40-3=-43[/tex]

[tex]\sf 10x-43[/tex]

_______________

[tex]\sf 5x-13=10x-43[/tex]

[tex]\boxed {\sf Add\: 13 \:to\: both\: sides:}[/tex]

[tex]\sf 5x-13+13=10x-43+13[/tex]

[tex]\sf 5x=10x-30[/tex]

[tex]\boxed{\sf Subtract\: -10x\: from\: both\: sides:}[/tex]

[tex]\sf 5x-10x=10x-30-10x[/tex]

[tex]\sf -5x=-30[/tex]

[tex]\boxed{\sf Divide \:both \:sides\: by \:-5:}[/tex]

[tex]\sf \cfrac{-5x}{-5}=\cfrac{-30}{-5}[/tex]
