Answer:
Step-by-step explanation:
<u>Area formula:</u>
<u>The height is:</u>
- h = (x + 2)sin 45° = √2(x + 2)/2
<u>Substitute the area value an set an equation:</u>
- 4√2 = (2x - 3)√2(x + 2)/2
- (2x - 3)(x + 2) = 8
- 2x² + x - 6 = 8
- 2x² + x - 14 = 0
- D = 1 + 4*2*14 = 113
- x = (-1 + √113)/4 = 2.41 (rounded)
Note. the second root ignored as negative
Answer:
2/11 or 18 %
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 3 - 2 = 1, thus
= 2 + (43 × 1) = 2 + 43 = 45
Answer:
17.5 gallons of water was dispensed
Step-by-step explanation:
Total amount of water dispersed= (Amount of water dispersed to each rider×Number of Riders) where;
Amount of water dispersed to each rider=5/8 gallons
Number of Riders=28
Substituting;
(5/8)×(28)=17.5 gallons
