Answer:
explanations: we multiply with a rational surd
(x-9)*√(x+9)/(√(x-9)*√(x+9)
=(x-9)√(x+9)/
B.( x-9)/√x+3 =( x-9)*(√x-3)/(√x+3)*(√x-3)
= (x-9)*(√x-3)/x-9
=√x-3
Answer:
The answer is 1825.35
Step-by-step explanation:
Since the first week isn’t included, we only count 4 weeks.
So first, 2000 x 0.03 = 60
(By the way 0.03 is 3%)
2000 - 60 = 1940
Subtracting 2000 by 60 represents the amount of money the aquarium went down in that week.
Then, week 3:
1940 x 0.03 = 58.2
1940 - 58.2 = 1881.8
Now, the last week, week four:
1881.8 x 0.03 = 56.45
1881.8 - 56.45 = 1825.35.
Therefore, 1825.35 after 5 weeks.
Word problems are the best to model real world problems. Most word problems use real world situations and problems that need a solution that can be solved through operations
Answer:
Step-by-step explanation:
<u>Area of triangle:</u>
We have the value of b but not h.
Added auxiliary segments which help to find the value of h.
<em>See attached for details</em>
- sin 40° = h/4
- h = 4 sin 40°
- h = 2.57 km
<u>The area is:</u>
- A = 1/2*6*2.57 = 7.71 km²
P = 2(L + W)
P = 264
W = 54
264 = 2(L + 54)
264 = 2L + 108
264 - 108 = 2L
156 = 2L
156/2 = L
78 <=== Length is 78 yards
