Step2247 [10]

Answer:

130

Step-by-step explanation:

Given the equation of the relation as c(h) =50 +20 h where c(h) is the total cost for h hours and h is the number of hours of use, then to find the cost of jet ski if 4 hours were used will be;

c(h)=50 +20 h

c(4)=50 +20*4

c(4)=50 +80

=130

What are the coordinates of point S? On a coordinate plane, point S is 0.75 units to the left and 0.5 units up. (Negative three-

ZanzabumX [31]

Answer:

The coordinates of S is $( \frac{-3}{4}, \frac{1}{2})$

Step-by-step explanation:

We are supposed to find the coordinates of point S

Point S is 0.75 units to the left

So, x coordinate of point S = -0.75 = $\frac{-3}{4}$

Now we are given that point S is 0.5 units up.

So, y coordinate of point S = 0.5 = $\frac{1}{2}$

So, The coordinates of S is $( \frac{-3}{4}, \frac{1}{2})$

So, Option A is true .

Let n = 60! + 55! + 50! the unit digit of n and a number of digits to the left of the units digits are consecutive zeros before

Archy [21]

n=8320987125437793528348710310901843271933297732006335848276356027645952000000000000

So you can see there are 12 zeros before you hit the first non-zero, which is 2.
