A number (a) rounded to the nearest 10 is 240. Another number (b) rounded to the nearest 100 is 300. a and b are whole numbers. What is the greatest difference between a and b?
Answer:
64
Step-by-step explanation:
a = 235
b = 299
d (difference) = b - a
d = 299 - 235
d = 64
Why can you not do negative numbers to the power of 1. 5?.
Answer:
Lets say we have (-1)^(1.5)
Step-by-step explanation:
(-1)^(1.5) = (-1)^(3/2)
= (√(-1))^3 which has no solution in the real number field, as √(-1) does not exist.
In the complex number field √(-1) = i, and (-1)^(1.5) = i^3 = -i.

Assume:
+There are 365 days a year
+No spoilage issues
+Pi= 3.14
Answer: Assume π = 3.14(rounded upto two decimal point)
Case I. 1 year = 365 days
2 years = 730 days
3 years = 1095 days
And .14 years = 51 days 2 hours 24 minutes
So, 3.14 years = 1146 days 2 hours 24 minuts.
Now, suppose you born in a leap-year.
Case II. 1 year = 366 days
2 years = 732 days
3 years = 1098 days
and .14 years = 51 days 5 hours 45 minutes 36 seconds
Then, 3.14 years = 1149 days 5 hours 45 minuts 36 seconds
So, yes, it is possible to be exactly π years old. At exactly 1146 days 2 hours 24 minutes or 1149 days 5 hours 45 minutes 36 seconds (in case of a leap-year born), we could have celebrate at our π years birthday.

identify the triangle please hurry
First off, no sides have the same length as the others, so it cannot be an equilateral or an isoceles triangle, as it would required at least 2 sides to have the same length.
So, we're left with scalene triangle options.
There is an angle that is an obtuse angle (as it is more than 90 degrees and less than 180 degrees), so this is a scalene obtuse triangle.

Sal’s pizza shop can make 7 pizzas in 15 minutes. At this rate, how many pizzas can they make in 4 hours?
Answer:
112 pizzas
Step-by-step explanation:
There are 60 minutes in an hour, means that Sal's pizza shop can make 28 pizzas an hour. Multiply this by 4 to get 112
Answer:112
Step-by-step explanation: I got you Breh
You see first you divide 4 hours by 15 minutes and you get 16 minutes.
To confirm that you can do 16 x 15 and it would be 240, and 4 hours is 240 miniutes.

What is the positive solution to the equation 5x2+2=47
Answer:
X=3, or X=-3 But the positive answer is X=3
Step-by-step explanation:
Rewrite the equation 5x^2+2=47
Subtract 2 from each side -----> 5x^2+2-2=47-2
Simplify ---------> 5x^2=45
divide each side by 5 -----> 5x^2/5=45/5
Simplify x^2=9
Divide each side by using square root method --> Sqrt(9) - sqrt(9)
Now simplify to get X=3, or X=-3

Answer: Joining a gang will not give you more protection; it could enhance your chance of being targeted as a victim. Gang members make far less money than those who do not join gangs. Gang members usually don't get a good education, making it hard to find a good job. Gang involvement increases your risk of being arrested, having to go to court, being put on probation or parole, being jailed, injured, or even killed. Being a gang member is a dangerous thing. Often, members realize this once they have joined the gang and want to leave. It is never easy to leave a gang because as a member you have information that could be shared with authorities like the police – and as a result, get the gang members in trouble. You would always be getting in trouble with the law because you would apart of a gang group. Gangs often steal, break in peoples houses, break in to their cars and etc. Gang members leave you to take the blame so the other ones would not get caught and go to jail. Being in a gang is really bad for you because if you did didce to leave the gang then they might come and kill you and your family because they have no respect for other people.

Once a week Mrs. Baker makes sugar cookies.
The first week she makes the recipe, she uses
the 2 full cups of sugar called for. Each week
after that, she reduces the amount of sugar
by one third. How much sugar does she use
for cookies over 8 weeks? (Hint: The common
ratio is not 1/3.)
By getting the exponential decay that models the situation, we will see that after 8 weeks she uses 0.12 cups.
How much sugar does she use each week?
We know that the first week, she uses 2 cups of sugar, and each week she uses removes one-third of what she used the previous week.
Then the second week she uses:
S₂ = 2 cups - (1/3)*(2 cups) = 2 cups*(1 - 1/3) = 2 cups*(2/3)
The third week she uses:
S₃ = 2 cups*(2/3) - (1/3)*2 cups*(2/3) = 2 cups*(2/3)^2
You already can see the pattern, at week x, she will use:
Sₓ = (2 cups)*(2/3)^(x - 1)
This is an exponential decay.
To get how much sugar does she uses after 8 weeks, we just replace x by 8 in the above equation:
S₈ = (2 units)*(2/3)^(8 - 1) = 0.12 cups of sugar.

Two circles centered at the origin are graphed on the coordinate plane. The smaller circle has a radius of 2 units and the larger circle has a radius of 8 units.
The equations that describe the given circles are:
x^2 + y^2 = 4
x^2 + y^2 = 64
How to get the equations for the circles?
For a circle of radius R, centered at the point (a, b), the equation is:
(x - a)^2 + (y - b)^2 = R^2
In this case, we have two circles, both centered on (0, 0), but one has a radius of 2 units and the other a radius of 8 units, then we have two equations:
x^2 + y^2 = 2^2 = 4
x^2 + y^2 = 8^2 = 64
These are the two equations that describe the given circles.

27=−5x+3
x=−20 1/2
x=−19
x=−16
x=−14 1/2
Answer:
x = -24/5
none of the options listed
Step-by-step explanation:
27=−5x+3
the choices all have x listed as a positive number, so we need to fix the question by moving 5x to the other side of the = and changing its sign.
27 +5x= 3
then move the 27
5x= 3 -27
then subtract
5x = -24
then divide both sides by 5
x = -24/5
