Answer:
530.66 cm²
Step-by-step explanation:
take half the diameter of 26 and that gives you the radius of 13
A =π· r²
A = 3.14 x 169
One half is 0.50, so compare 0.84 to 0.50. Which is true?
0.84 is greater than 0.50
0.84 equals 0.50
0.84 is less than 0.50.
Answer:
11/15 < 4/5
Step-by-step explanation:
1. 5/6 = 10/12, so the first answer is not correct
2. 1/4 = 4/16, so the second answer is not correct
3. 3/4 = 9/12 and 4/6 = 8/12, so the third answer is not correct
4. 4/5 = 12/15 > 11/15, so this answer is correct
Answer:
X = 2
Step-by-step explanation:
Divided 26 (total perimeter) by 4 = maximum side length possible = 26÷4 =.6.5
I used the trial and error technique
Guessed it was 2 working out to see if i was right or wrong:
Length: 2(2) + 3 = 4+3 = 7
Width: 3(2) = 6
7+7+6+6 = 26
Therefore X = 2
We need to start from the innermost parenthesis and work our way out.
The first parenthesis is
. These are not like terms because one involves a variable, while the other is a constant term. Two terms are summable if they involve the same power(s) of the same variable(s).
So, we can take one step outwards, and we arrive to the square brackets. We have

and 2z and -13z are like terms, so we can sum them:

Finally we arrive to the whole expression, which is

Because, again, 5z and 11z were like terms.
