A tennis player keeps track of the number of successful first serves he makes. During the first 8 service points of a game, only
Andru [333]

Answer:

He needs 7 more consecutive successful first serves to raise his first serve percentage to 60%.

Step-by-step explanation:

After n consecutive serves, his total number of serves is going to be n+8, since he has already served 8 times. In the best case, his number of successful first serves is n+2.

His percentage of succesful first serves is the division of the number of succesful first serves divided by the total number of serves. So

P = \frac{n+2}{n+8}

We want P = 0.60. So

0.6 = \frac{n+2}{n+8}

n+2 = 0.6*(n+8)

n + 2 = 0.6n + 4.8

n - 0.6n = 4.8 - 2

0.4n = 2.8

n = \frac{2.8}{0.4}

n = 7

He needs 7 more consecutive successful first serves to raise his first serve percentage to 60%.

Does 15/25 x 25/15 = 0?
sergejj [24]
No, it does not equal 0. Lets multiply it out and see what it actually equals.
15/25 * 25/15
15*25 / 25*15
375 / 375
Anything over itself is 1, so the final answer for the multiplication is 1.

How do I️ graph y+2x=3
algol [13]
Y + 2x = 3....put this in y = mx + b form by subtracting 2x from both sides
y = -2x + 3

so u have a slope of -2 and a y int of 3 or (0,3)

ur x int can be found by subbing in 0 for y and solving for x
y + 2x = 3
0 + 2x = 3
2x = 3
x = 3/2 or 1.5....so ur x int is (1.5,0)

so go ahead and plot ur intercepts (1.5,0) and (0,3).....and since u have a slope of -2, start at (0,3)....come down 2 spaces, then go right 1 space....plot that...then down 2 and to the right 1...plot that...keep doing this and u should cross the x axis at (1.5,0)....then connect ur plotted points and u have ur line.

1000 ft to 1950 ft in 4 miles what is slope
noname [10]

Answer:

0.05

Step-by-step explanation:

Slope is the vertical drop or rise to the horizontal distance;

   Slope  = \frac{vertical interval}{horizontal distance}  

 Let us convert 4 miles to feet;

         1 mile  = 5280ft

        4 miles  = 4 x 5280 = 21120ft

Slope  = \frac{1950 - 1000}{21120}   = 0.05

The slope is 0.05
