24 written as a percentage

Answers

Any number is equal to that number over 1

So x is equal to x/1

Same thing with 24. 24 = 24/1

To get it into percent we multiply by 100 so:

\sf{(24)/(1)=(24*100)/(1*100)}

And simplifying that we get

\sf{(2400)/(100)}

And x/100 = x%

so 2400/100 = 2400% 

So your answer is 2400% :)

What is the take from ten strategy

Answers

It is like when you have the problem 15*6, you don't know how to do that mentally, unless you use the take ten strategy which would turn it into (10*6) + (5*6) so, it simplifies to (60) + (30) which is 90

PLS HELP ME WITH THIS QUESTIONNN

Answers

Answer:

F 1/36

Step-by-step explanation:

There are 3+5+10 = 18 markers in the drawer

P (green) = green/total =3/18 = 1/6

P( green,green) = P(green) * P (green)

                          = 1/6* 1/6 = 1/36

Getting 2 greens in a row with replacement is 1/36

What is the initial value of the function represented by this graph

Answers

Answer:

The initial value of the function is 5

Step-by-step explanation:

we know that

The initial value of the function, is the value of the function when the value of x is equal to zero (the y-intercept)

In this problem

Observing the graph

The y-intercept is the point (05)

therefore

The value of the function for x equal to zero is 5

The cone shown has a radius of 5 feet and a slant height of 12 feet. Which choice is closest to the total surface area? Use 3.14 to approximate pi.60 square feet


79 square feet


188 square feet


267 square feet

Answers

So first of all, to solve this, we need to know the formula for finding the surface area of a cone. The formula is :
SA = \pi r(r+ \sqrt{ h^(2) + r^(2) } )
Where SA stands for surface area, h stands for height, and r stands for radius.
In the given information, we are not told the height, but we are told the slant height.

In a cone, the slant height, the height, and the radius together form a right triangle. We can use that triangle to solve for the height
So, to find the height, we can do:

5^2+b^2 = 12^2, or 25+b^2 = 144
Therefore, b is equal to about 11

So now, we can plug all of our values into the formula
This gives us:
SA = \pi * 5 (5+ \sqrt{ 5^(2) + 11^(2) } )

If we solve, this gives us about 267. 

Therefore the answer is 267 feet squared

Hope this helped!! :D
sa=π•r(r+√h²+r²
sa=π•r²+r•√h²+r²
sa=3.14•5²+5•√11²+5²
sa=78.5+5•12.08
sa=267
