Answer:
StartFraction 16 over 81 EndFraction
Step-by-step explanation:
There are 4 prime numbers from 2 to 10 (2, 3, 5, 7) and 9 numbers from 2 - 10. Total possibilities: 9 * 9 = 81
Prime possibilities: 4 * 4 = 16
Therefore the answer is 16/81 or StartFraction 16 over 81 EndFraction
-16t^2 + 25t + 8 = 10
-16t^2 + 25t - 2 = 0
t = 1.48 seconds
If he spent half his savings on supplies and the other half on lunch he shouldn't have money left over. It's a trick question.
First find the slope,
m=(y2-y1)/(x2-x1)=(1-(-9))/(7-6)=10
Next, use the point slope form to find the equation:
L : y-y1=m(x-x1) => y-1=10(x-7)
[in point slope form, point is (7,1), slope=m=10 ]
4h+3=The Pay of Shea
3.5h +6= The pay of Kelly
4h+3=3.5h+6
-3 -3
4h=3.5h+3
-3.5h
.5h=3
*2 *2
h=?
Then stick "h" into one of the original equations and solve for someones pay to get "p"
3.5(h)+6=p OR 4(h)+3 =p
