Answer:
The answer to your question is 14.5 weeks
Step-by-step explanation:
Data
Total cost = C = $87
money earned = m = $6
Number of weeks to have the money = w = ?
Process
1.- Write an equation that represents the situation
Weeks = Total cost / Money earned
w = C/m
2.- Substitute the values
w = 87 / 6
3.- Result
w = 14.5
4.- Conclusion
Niki will last 14.5 weeks to have enough money to buy a dog bed.
Quick answer
Any irrational number. I can't think of any exception to this statement.
sqrt(5) is irrational. 1/2 * sqrt(5) is still irrational.
-sqrt(5) is irrational. -1/2 * sqrt(5) is still irrational
2 + sqrt(5) is irrational. Multiplying this by 1/2 is still irrational.
1/2(2 + sqrt(5) = 1 + 1/2 * sqrt(5) ) is irrational.
Conclusion
There are no exceptions to this. All irrational numbers produce irrationals when multiplied by 1/2
Answer: A. They are both incorrect
Step-by-step explanation:
x=3√2
y=6
z=3√2
-----------------------
45-45-90=1:1:√2
------------------------
solve for x
x is the side accordingly to 90 in the smaller triangle, so it should be the [45] side times √2
3×√2=3√2
-----------------------
solve for y
y is the side accordingly to 90, so it should be the [45] side times √2
3√2×√2=6
----------------------
solve for z
z is the side accordingly to 45 in the bigger triangle, x is also accordingly to 45 in the bigger triangle
z=x
z=3√2
The base b of a logarithmic function should be greater than zero and not equal to 1. Therefore, the first and second choice is the only ones left possible:
b> 0 and b = 1
b > 0 and b=/ 1
but it was stated earlier that the value of b should not be equal to 1, therefore, the answer is
b > 0 and b =/ 1<span />
Answer:
49
Step-by-step explanation:
12 hotdogs per min × 8 minutes = 96
145-96= 49
So he will have 49 hotdogs left.
