The cooper's weight as an adult dog will be 90 pounds.

What is percentage?</h3>
Percentage, which is a relative figure used to denote hundredths of any quantity. One percent (symbolized as 1%) is equal to 100 parts; hence, 100 percent denotes the complete amount, and 200 percent designates double the amount specified.
A typical method for calculating a percentage is the formula shown below:
- Determine the total amount of what you want to find a percentage.
- Divide the number to determine the percentage.
- Multiply the value by 100.
Calculation for the weight of Cooper as an adult;
Cooper's present weight is 20 pounds.
He will weigh about 350% as much as his current weight.
Calculate 350% of 20 pounds.
= (350×20)/100
= 70
The increment of the weight of Cooper will be 70 pounds.
Thus, the total weight is 20 + 70 = 90.
Therefore, the weight of Cooper after 350% as an adult would be 90 pounds.

Answer:
(1) 9
(2) 
(3) 6()
Step-by-step explanation:
From the question,
(1) (
)²
Applyin the law of multiplication of surds
()² = (
(2) (
)× (
) =
Also applying the the law of multiplication of surd
(
)×() = () ( This is an irational answer)
∴ ()×() =
(3) 2()×3()
Also applying the law of multiplication of surds i.e Multiply surds to surds and whole number to whole number
= 2×3×()×()
6×() = 6(
Given:
Total number of calculators in a box = 10
Defective calculators in the box = 1
To find:
The number of ways in which four calculators be selected and one of the four calculator is defective.
Solution:
We have,
Total calculators = 10
Defective calculators = 1
Then, Non-defective calculator = 10-1 = 9
Out of 4 selected calculators 1 should be defective. So, 3 calculators are selected from 9 non-defective calculators and 1 is selected from the defective calculator.
Therefore, the four calculators can be selected in 84 ways.
To find the mean, you add up the numbers and divide by
how many numbers there are.
So if the mean of 'A' and 'B' is 40, then A + B = 80 .
And if the mean of 'B' and 'C' is 35 then B + C = 70.
==========================================
You said that (A + B) + C = 100 .
From something else that you said, I noticed that A + B = 80 .
So I can write (80) + C = 100
Subtract 80 from each side: C = 20
==========================================
I also noticed, from what you said, that B + C = 70 .
So I can write B + 20 = 70
Subtract 20 from each side: B = 50
==========================================
Now I know that C = 20 and B = 50.
Finally, you said that A + B + C = 100 ,
So I can write A + 50 + 20 = 100
Combine like terms on the left: A + 70 = 100
Subtract 70 from each side: A = 30
==========================================
<em> A = 30</em>
<em> B = 50</em>
<em> C = 20</em>
Answer:
The answer would be 70000, because the 10 is powered to 4 you have to put down 4 zeros and since the equation is 7×10^4 you have to put down a 7 before the 4 zeros, therefore the answer would be 70000
