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: Third option.
Step-by-step explanation:
By definition, Rational Functions have the following form:
Where 
and 
are polynomials.
The Restrictions of the Domain of Rational Functions are those Real numbers that make the denominator equal to zero, because the division by zero is not defined.
In this case, you have the following Rational Function:
The Restrictions of the Domain can be found applying this steps:
- Make the denominator equal to 0:
- Solve for "x":
Then, the Domain of this function includes all "x" not equal to 2.
Therefore, the answer is:
Let the number = 10x+y
x+y = 9
y-x = 1
(x+y)+(y-x) = 9+1
2y = 10
y = 10/2
<h3><u>y = 5</u></h3>
x+y = 9
9-y = x
x = 9 - 5
<h3><u>x = 4</u></h3>
<h2>So, your number is <u>45</u></h2>

Answer:
150 ft^3
.1 ton or 200 lbs
Step-by-step explanation:
The volume is given by
V = l*w*h
V = 5*5*6
V = 150 ft^3
To find how much 1 ft^3 weighed take the weight and divide by the volume
15 tons / 150 ft^3
.1 ton / 1 ft^3
1 ft^3 weights .1 ton
We know that 1 ton = 2000 pounds
.1 ton = 200 pounds

Split the figure into 2 different shapes. We’re gonna split it where the 19 line is. So now you have sort of a square and a rectangle. You need to find the area of each. If the line in bottom is 35 and the rectangle top line is 19, just subtract 19 from 35 and you get the bottom line of your square. Same for the 25 on the left of the whole figure. Do the same with figure band divide where the 7 line is. Find the area of each
