Answer:
400 in²
Step-by-step explanation:
(20×16) + (½×8×20)
320 + 80 = 400 in²
Answer:
2550 miles in 6 hours
Step-by-step explanation:
if you divide the miles and hours by each other you will get the m/ph (miles per hour)
3400 ÷ 8 = 425
now, that we know the plane travels 435 m/ph, then if we multiply it by 6 we will get the answer
425 × 6 = 2550
So remember the formula for working out the slope:
(y2 - y1) ÷ (x2 - x1)
We already know two points:
(11, 5) and (20, 5) (Remember points are like (x, y)
Therefore y2 = 5 and y1 = 5 and x2 = 20 and x1 = 11
Substitute these into the formula from the start:
(y2 - y1) ÷ (x2 - x1)
(5 - 5) ÷ (20 - 11)
0 ÷ 9
And we can determine the slope is equal to 0 as 0 ÷ 9 = 0
Answer:
31.929
Step-by-step explanation:
29.95×6/100=1.797
29.95+1.797=31.929
Your guesses are correct.
