Answer:the weight after 225 days is
22885 kilograms
Step-by-step explanation:
The initial weight of the blue whale calf at birth is 2725 kilograms. blue whale calf gains 90 kilograms of weight each day for the first 240 days after its birth. The weight increases in arithmetic progression. This means that the first term of the sequence, a is 2725, the common difference, d is 90.
The formula for the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
n is the number of terms of the sequence.
a is the first term
d is the common difference
We want to determine its weight, T225 after 225 days after it’s birth. It means that n = 225
Therefore
T225 = 2725 + (225 - 1)90
T225 = 2725 + 224×90 = 2725 + 20160
T225 = 22885
Answer:

Answer:
Step-by-step explanation:
My recommendation is try to find a finals for both pre-algebra or algebra after learning some of the material ahead of time and after taking them, find which one is more comfortable for you
Good luck!
Since the square root of 64 is 8, 8 has an absolute value, so it can be opposites as it, eg. 8 = -8.
The equation whose solution is the given quantity is 90,000,000 = 2,000,000w + 15,000w where w = $44.67
<h3>Equation</h3>
B = xz + yw
Where,
- B = Total cost = 90
- x = number of fighter plane = 20
- y = tons of wheat = 15,000
- w = cost of each tons of wheat
- z = cost of fighter plane
- z = 100,000w
B = xz + yw
90,000,000 = (20 × 100,000w) + (15,000 × w)
90,000,000 = 2,000,000w + 15,000w
90,000,000 = 2,015,000w
w = 90,000,000 / 2,015,000
= 44.6650124069478
Approximately,
w = $44.67
