Answer: a) 154 kilograms
Step-by-step explanation:
Given : Daisy, the african elephant weighs 10,250 pounds.
The daily feed intake for an elephant is approximately 1.5% of the animals body weight.
1.5% can be written as 0.015.
Now, the amount of feed is to be feed to Daisy to meet her requirements will be :_
Hence, 154 kilograms of feed is to be feed to Daisy to meet her requirements.
Answer:
5r^3 + 4r^2 - 8r + 16
Step-by-step explanation:
(8 + 5r^3 - 2r^2) - (8r - 8 - 6r^2) =
The first set of parentheses is there just to show you that what is inside is a polynomial. The second set of parentheses has a second polynomial inside. The subtraction sign just to the left of the second set of parentheses shows that you are subtracting the second polynomial from the first one.
The first set of parentheses is not needed and can be dropped.
You are subtracting the second polynomial fromt he first one, so you can think of the the subtraction sign as a -1, and you need to distribute the -1 by the second polynomial, That will result in all signs inside the second set of parentheses changing.
Below, just the first set of parentheses is removed.
= 8 + 5r^3 - 2r^2 - (8r - 8 - 6r^2)
Now, we change every sign inside the second set of parentheses by distributing -1.
= 8 + 5r^3 - 2r^2 - 8r + 8 + 6r^2
Now we need to combine like terms. Like terms have the same variable part. We can rearrange the terms grouping like terms together before combining them. Also, it is customary to list the terms in descending order of degree.
= 5r^3 - 2r^2 + 6r^2 - 8r + 8 + 8
Now we combine like terms.
= 5r^3 + 4r^2 - 8r + 16
Answer: $10.90
Step-by-step explanation:
Skittles-1.44
M&M's-3.744
Pretzels-5.72
Not sure if its a typo, thats if theres 3.12lbs of of M&M's
The answer is theres 312 M&M's is 374.4
Answer:Y= -2x-5
Step-by-step explanation:
What is the Equation of the line that passes through the point (-3,1) and has a slope of -2
Y=mx+b
Y= 1
X=-3
M=-2
1=-2(-3)+b
1= 6+b
1-6=b
-5=b
Y= -2x-5
