Answer:
6,535.06 feet
Step-by-step explanation:
The set up is right angles
hypotenuse = 7000feet
angle of elevation = 21 degrees
Required
horizontal distance (adjacent)
Using SOH, CAH TOA trig identity
cos theta = adj/hyp
cos 21 = adj/7000
adj = 7000 cos 21
adj = 7000(0.9336)
adj = 6,535.06
Hence the HORIZONTAL distance until the plane flies over the island is 6,535.06 feet
Answer:
73.9
Step-by-step explanation:
multiply 5.50 by 8 and 14.95 by 2
EDIT: then add the products together
Answer:
$1,855
Step-by-step explanation:
Rent per year = $15.90 psf
Hence,
Rent per month = 15.90/12 psf = $1.325 psf
Rent of the store per month
= 1400 * $1.325 psf
= $1,855
2a + 8b + 10
-3a + 7b + 16
2a + 8b + 10 - 5a -b +6= -3a + 7b +16
Next, group the similar figures
2a - 5a + 8b - b + 10 + 6= -3a + 7b + 16
Answer: 83
Step-by-step explanation:
Since the student want to have a mean of 83 in the 7 tests, the total score of the tests will be:
= 83 × 7
= 581
Then, we add the value of the 6 tests and this will be:
= 88 + 73 + 81 + 83 + 79 + 94
= 498
We will now subtract 498 from 581 and this will be:
= 581 - 498
= 83
He needs to score 83 in the 7th test
