convert 55/100 to a decimal, please
Answer:0.55
Step-by-step explanation:
OK decimal means one number before (.) (point)
for example if question is
1.) 55/10 = ans: 5.5 (here before . (point) 5 is there only one number
2.)55/1000= ans: 0.055(here before .(point) 0 is there only one number
3.)like ur question 55/100= 0.55 ☻
Answer: 0.55
Step-by-step explanation:
Because 55/100 is 55% and 55% in decimal form is .55. Always move the decimal to the right when the percentage is under 100%.

In ordinary arithmetic, the expression has no meaning, as there is no number which, when multiplied by 0, gives a (assuming a ≠ 0), and so division by zero is undefined. Since any number multiplied by zero is zero, the expression 00 is also undefined; when it is the form of a limit, it is an indeterminate form. explanation:

Find the area and circumference of a circle with a diameter of 48 cm. Use 3.14. :) Thanks!
Answer:
C=150.72 cm
A=1808.64 cm square
Step-by-step explanation:
If you are given the diameter(radius) of a circle you can find the area and the circumference of a circle.
since d(diameter)=2r(radius)
48=2r
r=24
[tex]C=2\pi r\\ C=2*3.14*24\\C=6.28*24\\C=150.72cm[/tex] If we found the circumference only the area is left.
[tex]A=\pi r^{2} \\A=3.14*24^{2} \\A=3.14*24*24\\A=3.14*576\\A=1808.64 cm^{2}[/tex]
Brainliest ? For which inequality is (0,0) a solution?
Answer:
C. y-5>3x-7
Step-by-step explanation:
If you multiply y and x to 0 you get -5 > -7
Answer:
C. y-5>3x-7
Step-by-step explanation:
The point (0, 0) would be a solution because the inequality is greater than or equal to. Since the 2 sides become equal, the inequality is true which means (0, 0) is a solution.

Which of following lies between 0 and -1 ?
Answer:
Step-by-step explanation:
There are many numbers that lie between 0 and -1
Some common numbers are -1/4 , -1/2 , -3/4 , etc.........
Other numbers can be found by multiplying the numerator and denominator by the same number for example, 10
0/1 × 10/10 = 0/10
-1/1 × 10/10 = -10/10
Now the numbers between 0/10 and -10/10 are :
-1/10, -2/10....................................-9/10 etc.

What is rational number?A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. For example, −3/7 is a rational number, as is every integer.
To find the number lies between 0 and -1, we have to
0/1 and -1/1
0/1* 10/10 and -1/1*10/10
so, we have to find in between 0/10 and -0/10
-1/10, -2/10, -3/10, -4/10, ............................ -9/10
Hence, the numbers are -1/10, -2/10, -3/10, -4/10, ............................ -9/10.

A function models the growth of a sample starting with 40 bacteria with the ability to double every two hours. Which graph
models the function?
Answer:
The function is y = 40 * 2^(x/2)
The graph is in the image attached
Step-by-step explanation:
The function that models this growth is an exponencial function, that can be described with the following equation:
y = a * b^(x/n)
Where a is the inicial value, b is the rate of growth, x is the time and n is the relation between the time and the rate (the rate occurs for every two hours, so n = 2).
Then, using a = 40, r = 2 and n = 2, we have:
y = 40 * 2^(x/2)
If we plot this function, we have the graph shown in the image attached,
It is an exponencial graph, where the value of y increases very fast in relation to the increase of x.

The door to your bathroom has never closed well. In fact, every time you try to use the bathroom, the cats bust open the door because it simply won’t latch. You look at the door and it appears that the door frame is slightly tilted. The person who built your house claims that can’t be true because he measured your door frame and found it be an exact right angle. He claims what you’re seeing is an optical illusion. If you knew the door frame measurements were as pictured to the right, did the builder install your door frame correctly at a right angle?
Answer:
If the door was at the right angle then that means it is not an optical illusion, but if the door is straight then that means the door is not at a right angle so it's an optical illusion.
Step-by-step explanation:
Maybe if the door was straight, but you saw it at a right angle then maybe you were laying down, you were sick, seeing things or you drank a lot of alcohol that day. If it was a right angle on that day then it was not an optical illusion.
When a number is tripled, it gives the same result as when 32 is added to it.
What is the number?
Answer:
The number is 16.
Step-by-step explanation:
3x=32+x
2x=32
x=16
A number that when tripled, gives the same result as when 32 is added to it is 16.
Let the unknown number be x.In this exercise, you're required to solve for an unknown number, that when tripled has the same value as when 32 is added to it.
Translating the word problem into an algebraic expression, we have;
Tripling the number, we have:
[tex]3x[/tex] ....equation 1
Adding 32 to the number, we have:
[tex]32 + x[/tex] ....equation 2
Equating the two equations, we have:
[tex]3x = 32 + x\\\\3x - x = 32\\\\2x = 32\\\\x = \frac{32}{2}[/tex]
x = 16
