Answer:
Step-by-step explanation:
6 miles in 49 minutes = x miles in 1 minute
proportion time
6 x
------- = ------ cross multiply
49 1
49x = 6 ......divide both sides by 49
x = 6/49
x = 0.12244 rounds to 0.12 miles per minute <====
===============================
22 bucks for 5 hrs = x bucks for 1 hr...
22 x
------ = -------- cross multiply
5 1
5x = 22...divide both sides by 5
x = 22/5
x = 4.4.....so its $ 4.40 per hr <===
Answer:
-3
Step-by-step explanation:
use the equation y = mx + b where m is the slope and b is the y-intercept so just plug in what you know. y = 2/3x + 2 then solve the equation for x . To do that, just put y = 0 so then it would be -2 = 2/3x then -2/ 2/3 = x and -2 divided by 2/3 would be -3

76.8 words per minute
Step-by-step explanation:
Step-by-step explanation:
first of all, your teacher wrote nonsense in the answer options : an area is always given in squared units. never in cubed units (which would be volume).
the area is : 1/2 × perimeter × apothem
the perimeter is simply 12 × 5 = 60 meters.
apothem = (a/2)×cot(pi/12) = 5/2 × cot(pi/12) =
= 9.330127019... meters
so the area is
1/2 × 60 × 9.330127019... = 279.9038106... m²
therefore, the third answer option is correct (although it is m², and not m³).
by the way, you have question 3 wrong. I answered this with the correct apothem calculation in the explanation for question 4.
