What kind of operation is this ? it just says x and a nine.
Answer:
r = 5
Step-by-step explanation:
To solve for r, plug in the change in x values and change in y values, since the hypotenuse is simply the diagonal of both the y-coordinate and x-coordinates shown via drawing legs on the vertical and horizontal axis. So, since (0,0) is the initial point, r = sqr[(-4-0)^2 + (-3-0)^2 = sqr(16 + 9) = 5.
Now, the angle theta is the angle in which the sine, cosine, and tangent ratios are found. Simply use opposite over hypotenuse for sine, adjacent over hypotenuse for cosine, and opposite over adjacent for tangent using theta as the angle in which these values are obtained.
So... 4 folks, working for 8hours per day, do it in 15days
hmm alrite...so 4 folks working for 8hrs in 1 day, each one does 8, 4 of them, 4*8 = 32, so, they do 32 workhours every day, now for 15 days, that'd be 32*15, or 480
so, the whole job really takes 480 hours
now hmm let's see, the firm decides to increase the folks, but decrease the hours, so, 5 folks each working 6hours every day
how many workhours total? well 5*6 = 30
each is working 6hrs, 5 of them, so 30 workhours
how long will it take them if they only do 30 workhours everyday?
well the whole job is 480hours
Answer:
a>-21(1/3)
Step-by-step explanation:
3/4a>-16
first thing is to divide both sides by 3/4 to isolate the variable.
Since it is not negative, the sign stays the same.
-16/0.75=-21.3 repeating or just 1/3
Answer:
33
Step-by-step explanation:
- Fabric for 1 pillow case: 1.5 ÷ 3 = 0.5
- Amount of pillow cases made with 16.5 yards of fabric: 16.5 ÷ 0.5 = 33
I hope this helps!
