Answer:
<h2><u><em>
x = -2.27272727273</em></u></h2><h2><u><em>
in fraction</em></u></h2><h2><u><em>
x = -25/11</em></u></h2>
<u><em></em></u>
Step-by-step explanation:
Solve for X
6x+60x+150=0
66x = -150
x = -150 : 66
<u><em>x = -2.27272727273</em></u>
<u><em>in fraction</em></u>
<u><em>x = -25/11</em></u>
I) there are 360 degrees in a circle. So subtract all the numbers from 360 to get the angle for econ.
That angle is 65 degrees
ii) If 95 degrees represents 228 books, then 360 degrees represents "x" (total) books. So we have an equation:
<u>95</u> = <u>360</u>
228 x
Solve for x, and we get x = 864
iii) The percentage is 80 degrees out of 360 degrees or 2/9 or roughly 0.222 or 22.2%
To the nearest ten, 829 would become <em><u>830</u></em> because the ones digit (9) is closer to 30 than it is to 20. So we would round up.
To round to the nearest hundred, we look at the tens and ones digit. 29 is less than 50 so we would have to round down to <em><u>800</u></em> instead of rounding up to 900.
Hope that helps :)
Answer:
d) 2x(4x + 2)
Step-by-step explanation:
a) 4(2x + 1) = 8x + 4
b) 1/2(16x + 8) = 8x + 4
c) 2(4x + 2) = 8x + 4
d) 2x(4x + 2) = 8x² + 4x
Answer:
probability that the child DOES NOT play the piano
Step-by-step explanation:
A students' choir contains 25 children
n(S) =25
The number of students play the piano =5
Let 'E' be the event of the child play the piano so n(E) =5
The probability of that the child play the piano
Let 'E⁻ be the event of the child play does not play the piano
<u>Conclusion</u>:-
probability that the child DOES NOT play the piano
