Step-by-step explanation:
There should be 480 visitors (including children)
This would be because 60% of the people have 180 children so divide by 6 and you have 30 or 10%, multiply the 30 by 10 (to get a hundred percent [300] ) and add the children to get 480.
Answer: 3x^3 -8*x^2 + 8*x + 3
Step-by-step explanation:
The standard form for a plolynomial is:
a*x^n + b*x^(n-1) + c*x^(n - 2) ........
We have:
(x-1)(3x^2-5x-3)
this is equal to:
3*x^3 - 5*x^2 + 3*x - 3*x^2 +5*x + 3
where the thing that i did is distribute the multiplication
this is equal to:
3x^3 -8*x^2 + 8*x + 3
1/2(x - 7) = 11
<em><u>Distributive property.</u></em>
0.5x - 3.5 = 11
<em><u>Add 3.5 to both sides.</u></em>
0.5x = 14.5
<em><u>Multiply both sides by 2.</u></em>
x = 29. (This is your answer.)
We can plug 29 into the original equation to verify.
1/2(x - 7) = 11
1/2(29 - 7) = 11
1/2(22) = 11
11 = 11 √ This is correct.
Answer:
(C) The sum of the measures of ∠P, ∠Q, and ∠R is 180°
Step-by-step explanation:
All triangles, when their three angles are added up, gets us 180°.
This goes without saying, even with scalene triangles.
Additionally, the angles in squares add up to 360°, the angles in a pentagon add up to 540°.
Hope this helped!
