Answer:
0.5 meters
Step-by-step explanation:
In order to find the remaining amount of meters needed, we first need to find out how much Rita has as of now. To do that, we need to convert our lengths into meters.
1 meter=100 centimeters. Divide 250 centimeters by 100 to find how many meters it is. 250/100=2.5 meters
Next, 1 meter=1,000 millimeters. Divide 1,250 millimeters by 1,000 to find how many meters it is. 1,250/1000=1.25 meters
Add these lengths together (including the 3.75 meters). 1.25+2.5+3.75=7.5
Subtract this number from 8 to find the needed meters.
8-7.5=0.5
Rita needs 0.5 more meters of blue ribbon for her project.

Answer:
- insufficient information
- 7.2 miles
- 18.5 miles
Step-by-step explanation:
1. <u>Insufficient information</u>. We need to know the direction of one observer from the other, and the reference for the angles being measured.
__
2. See the first attachment. The law of sines tells you the distance r is ...
r = s(sin(R)/sin(S))
The angle at S is the supplement of the sum of the given angles:
∠S = 180° -35° -45° = 100°
Then the distance is ...
r = (10 mi)sin(45°)/sin(100°) = 7.1802 mi
The distance from Juan to the ship is about 7.2 miles.
__
3. See the second attachment. The law of sines tells you the distance 'a' is ...
a = b(sin(A)/sin(B))
a = (10 mi)sin(45°)/sin(50°) ≈ 18.4612 mi
The distance from airplane B to the airport is about 18.5 miles.
Each choice has 7x and 3x which multiply to 21x^2.
The original trinomial has positive 20 and positive 43, so all factors of 21 and of 20 must be positive.
Only choice B has all positive terms, so choice B must be the answer.
Price after discount = original price - discount.
price after discount = 16.99 - (16.99 x 0.20)
= 16.99 - 3.398
= 13.592 or $13.59
