7 is the square root or 49 because 7 times Itself would be 49. (7x7=49)
Answer:
the answer would be A.
Step-by-step explanation:
because the number of books(n) times 2, because they have twice the number of books divided hy fifteen so fifteen is below the line. im bad at explaning trust me
6²÷2(3)+4
Use the order of operations:
GEMDAS (grouping, exponents, multiplication/division, addition/subtraction)
First is grouping.
While there is a number inside parentheses, there aren't any operations in there we have to do first. The 2(3) is just another way to write multiplication. (2×3)
Second is exponents.
We do have an exponent here, 6².
The ² means to multiply something by itself. 6² = 6×6 = 36
Now our expression is 36÷2(3)+4
Next is multiplication/division. We can do these in any order. (either do the ×3 first or the ÷2 first, it doesn't matter)
Let's start at the left with 36÷2, which equals 18. (check: 18×2=36)
Now, we'll do the 18×3 = 54
If we were to do 36(3)÷2 that would work too-- 36×3÷2 = 108÷2 = 54.
Now while you can do these in any order, what you can <em>not</em> do is multiply the dividend 2 by 3. That would give 36÷6 = 6, which is incorrect. It's not something you need to fret over, just go from left to right doing your multiplication/division and you shouldn't ever have this problem.
Now we have 54 + 4 which is clearly 58.
Answer:
12 milk chocolates.
Step-by-step explanation:
-We know that probabilities add upto 1:
Let X be the total number of chocolates. We know that probability is the successful events divided by the total number of events:
#We subtract the number of dark chocolates from X to get the number of milk chocolates:
Hence, there must be 12 milk chocolates.
Answer:
r=1
Step-by-step explanation:
<u>Ratio of Values
</u>
A ratio compares two values by diving them. If the ratio is greater than one, then the value in the numerator is greater than the value in the denominator. The opposite relation gives ratios lower than 1. A ratio of 1 means both values are the same
We have a set of tiles numbered 1 to 30:
1,2,3,4,5,6...,29,30
Note that each odd-numbered tile is followed by an even-numbered tile. It means we have 15 odd tiles and 15 even tiles. The ratio is
r=1
