Answer:
7. 7.1+5.4+2.9=15.7
10.3+5.4=15.7
8. 373.4 - 152.9 = 220.5
373.4 - 153 = 220.4
220.4 - 0.1 = 220.5
9. 18.25 + 7.99 + 4.75 = 30.99
10. 1.05 + 3 + 4.28 + .95 = 9.28
11. 302.504
12 50.5
Answer:
The equation of a line is y = ax + b, where a is the slope and b is the y-intercept.
Since we have the y-intercept, all we need to do is find the slope. To find the slope, you need 2 coordinates.
The y-intercept is where the line crosses the y axis, so it is where x is 0. Since the y intercept is -2, that means the first coordinate is (0, -2)
The x-intercept is where the line crosses the x axis, so it is where y is 0. Since the x intercept is 4, that means the second coordinate is (4, 0)
Since we already have the y-intercept, all we do is put the slope in the equation: y = 1/2x - 2.

Step-by-step explanation:
4 administrator are eligible and the student relations committee has only 2 administrator there are C (4,2) ways of choosing the administrators for the student relations committee
similarly for faculty members ways (8,3) and for students C (20,5)
the number of possible committee = 4!/2!2! × 8!/3!5! ×20!/5!15!
= 6 ×56 ×15504
= 5,209,344
Answer:
19 paddle boards were rented.
Step-by-step explanation:
The rent of a surf board is $45
And the rent of a paddle board is $60
Total of paddle board and surf board rented were 44
let the paddle board rented be x
Hence, surf board rented will be 44-x
According to question we are given that 44 both boards were rented means


On solving the above equation we will get:



Hence, 19 the paddle boards were rented.
