Answer:
729 people chosen
Step-by-step explanation:
4 calculations in head when 3^2 = 9
3 calculations in head when 3^3 = 27
2 calculations in head when 3^4 = 81
1 calculations in head when 3^5 = 243
Answer found 3^6 = 729.
3 = 1st = 3^1
9 = 2nd = 3^2 3(3)
27 = 3rd = 3^3 9(3)
81 = 4th = 3^4 27(3)
243 = 5th = 3^5 81(3)
729 = 6th = 3^6 243(3)
<em><u>Question:</u></em>
The difference of two numbers is nine if the larger number is one more than twice the smaller number find a larger number
<em><u>Answer:</u></em>
<em><u>The larger number is 17</u></em>
<em><u>Solution:</u></em>
Let the smaller number be "a"
Let the larger number be "b"
The difference of two numbers is nine
Therefore,
b - a = 9 ------ eqn 1
larger number is one more than twice the smaller number
Therefore,
b = 1 + 2a ----- eqn 2
Substitute eqn 2 in eqn 1
1 + 2a - a = 9
<h3>a = 8</h3>
Substitute a = 8 in eqn 1
b - 8 = 9
b = 9 + 8
<h3>b = 17</h3>
Thus the larger number is 17
I do because x divided by y is the constant because y=kx
Answer:
Scale factor: 1.666
x: 10
Step-by-step explanation:
These are two similar triangles, the triangle MNO has been scaled off triangle FGH.
To calculate the scale/dilation factor, you take 2 measurements of a similar side and you calculate the ratio.
Since we have the measurements for segments GH and NO, and these are similar sides, we'll use that to calculate the scale/dilation factor of MNO over FGH.
Dilation factor is 5/3... or 1.666
if you're also looking for value of x, it would be 6 * 1.666 = 10
