Step-by-step explanation: Lets estimate first to the nearest whole number.
15.8 kilograms estimated is 16 kg
17.42 kilograms estimated is 17 kg
16.28 kilograms estimated is 16 kg
Now add the estimated values, 16 + 17 + 16 = 49 kg
The estimate gives you the correct answer because it gives you an accurate reasonable amount in this problem.
Answer:
The area of the kitchen is 84 square feet
Step-by-step explanation:
Let
x-----> the area of the kitchen in square feet
y ----> the area of the playroom in square feet
z ----> the area of the dining room in square feet
we know that
----> equation A
so
----> ---> equation B
----> ---> equation C
substitute equation B and equation C in equation A
solve for x
therefore
The area of the kitchen is 84 square feet
Answer:
2/3
4/6
8/12
Step-by-step explanation:
The answer is C... because after multiplying everything by itself that’s what you get.
The answer is the first option: it has the same domain as the function f(x) = - √(-x).
The domain is the set of x-values for which the function is defined.
The square root function is defined only for zero and positve values.
- x is positive when x negative.
So the domain for - √(-x) and √(-x) are the same: x less than or equal to zero.
