Jon has to pay $5.00
admission for the skating rink
and $2.50 per hour to rent
rollerblades. How many
hours can he skate for $15?
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
distance between the
points (3,7) (-5,16)

Check (24, 144, 145) is a Pythagorean triplet
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:
It is not a Pythagorean tripletThe cube of the sum of two
numbers x and y.
Find the value of x in the isosceles triangle shown below.
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.
[tex]a^2 + 2^2 = 8^2[/tex] [tex]a^2 + (2*2) = (8*8)[/tex] [tex]a^2 + 4 = 64[/tex] (Simplify both sides of the equation)[tex]a^2 + 4 - 4 = 64 - 4[/tex] (Subtract 4 from both sides)[tex]a^2 = 60[/tex] [tex]\sqrt{a^2} = \sqrt{60}[/tex] (Take square root of both sides[tex]a = \sqrt{60}[/tex]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.

I want to know the answer and how did u get it, I'm really lost in this subject
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]
Solve equation for 5(x - 3) + 2 = 5(2x - 8) - 3
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]

Blake bought a total of 24
doughnuts. Each doughnut cost
$0.84, including tax. Of the
doughnuts he bought, 5/8 were
glazed doughnuts. What was the
total cost of the glazed doughnuts?
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)
The total cost of the glazed doughnuts is $27.60i neeed the answer now please

lets talk about the basics of pythagoras (maths)?
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.

If 37 grams of pure drug are contained in 150 milliliters, how many grams are contained in 75 milliliter?
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
