The answer is X=10. Explanation: isolate the variable by dividing each side by factors that do not contain the variable.
A circle with a radius of 4 in, is dilated by a scale factor of 5. What will be the circumference of the circle after dilation?21 in 4 in 161 in 24 in
Answers
Ok so circumference=2*pi*radius. So We know that the radius is dilated by a scale factor of 5, so we can put 2*pi*20. For pi you can use So when we multiply 2*pi*20, you get 125.6637
Shanika is thinking of a rational number, but tells you its opposite. What is true about the number she is thinking of?
Answers
rational number is a number that can be written in form a/b where b is no equal zero and a is not a symbol (like pi or e or infinity)
tells you its oposite she chould tell you -a/b or b/a if she told you -a/b, then if you multiplied them together, you would get a negative number if she told you b/a, if you multiplied it by the original, you would get 1
where are the answer choises
5 1/3 + ( 2 1/3 + 1 1/3)=
Answers
okay so you want to do the parentheses first okay? So 2.3333...+1.3333333 is?3.666 or 3 2/3. So you got that right? So then 5 1/3+ 3 2/3. You get an easy 9. Because 1/3+ 2/3 adds up to 3/3, and is normally written as 1. So add a one to 5+3=8+1.
Use order of operations, by starting with the parenthesis first. 2 1/3 + 1 1/3 = 3 2/3. Then you would have to finish the rest of the problem by adding 5 1/3 to 3 2/3. Answer: 9
How do you solve the proportion: 11/5.9 = 15/x I learned this a while back I just forget how to do it. thx
Answers
You have to cross multiply and you get:
Multiply 15 by 5.9. Then divide by 11
