Answer:
second one is the answer
Step-by-step explanation:
To find f(4), you want to substitute x for 4 in the equation. It would look like:
f(4) = 3(4) - 6
Then, just do the math:
f(4) = 12 - 6
f(4) = 6
Hope this helps! :)
Answer:
23%
Step-by-step explanation:
Total: 1,302 +1,550+558 +124 +124+372+558 +558 +248 +310 +496=6200
Savings total: 310 +558 +558=1426
so...
1426/6200= 0.23
23%
Ok so to find the slope meaning how much quarts can be made in 1 hour you'd need to divide 140 by 7, if you do so you'll find 20. (20 quarts are made in an hour)
Now you can multiply 20 by 12, which is 240.
So, in 12 hours : 240 quarts of ice cream is made.
70 m * (100cm)/(1m) * (1 in)/(2.54 cm) = 2755.9 in
.
<span>Rough check, 1 m = 39.36 in approx , 70*39.36 = 2755.2

I think that's how it's done. As far as explaining it goes, I can't do that. I had to ask my math teacher and she wrote the calculations down.
