<span>36 does not belong in that group because it is the only number that is not a power of 2:
2^2 OR 2 x 2 = 4
2^3 OR 2 x 2 x 2 = 8
2^4 OR 2 x 2 x 2 x 2 = 16
2^5 OR 2 x 2 x 2 x 2 x 2= 32
2^6 OR 2 x 2 x 2 x 2 x 2 x 2= 64</span>
Let x = the width of the border
2x+23) by (2x + 33) are the overall dimensions of the pool and the border. Use the area to find x!
Overall area - pool area = 660 sq/ft (aggregate area)
(2x+23)*(2x+33) - (23*33) = 660
Solve.
4x^2+112x = 660
4x^2+112x−660=0 → subtract 660 on both sides
4(x−5)(x+33)=0 → factor
x−5=0 or x+33=0 → set both factors equal to 0
x = 5 or x = -33
In this case, we would use the positive solution, so the strip can be 5 ft. wide!
I hope this helps :)
As you can see, 4 of the 24 students don't partecipate in any activity. This clearly implies a ratio of 4:24, or 1:6.
We could infer that this ratio holds for the whole school, or even for all the boys and girls of that age.
That's the point of surveys and inferring: you gather data about a relatively small group, and then assume that the proportions you have are valid for a much larger group.
That's why it is important that the group that you survey is balanced and unbiased.
Answer:
$28.00
Step-by-step explanation:
You start with 35.00.
Now 10% of this is 3.5.
Multiply by 2 because it's 20%.
You get 7, so 7 is 20% of 35.00.
35.00 minus 7 is 28.00.
The pair of pants will be 28.00 dollars!
Answer:
the answers are: b, c, and e
Step-by-step explanation:
since line m is pointing down, the slope is negative
since line n is pointing up, the slope is positive
since line m's y intercept is 2, and line n's intercept is -3, and 2 is greater than -3, the y intercept for line m is greater than that of line n
