You look at the decimal place next to the hundredth one. In this case, it’s 4 so you round down
18.19 is the answer
Hack:
x% of 100=x
88% of 100=88
times both sides by 6
88% of 600=6 times 88
88% of 600=528
answer is 528
Given ---›
y = -3
&
y = x - 0.8
So,
=> x = y + 0.8
=> x = -3 + 0.8
=> x = -2.2
Therefore, the best approximation for the solution to this system of equations is = (–2.2, –3)
Answer:
See explanation.
(Before continuing reading, I took the base to be 3. Please tell me if you didn't want the base to be 3.)
Step-by-step explanation:
I assume 3 is suppose to be the base. Let's list some values that can be written as 3 to some integer.
3^0=1
3^1=3
3^2=9
3^3=27
3^4=81
3^5=243
......
I could have also did negative integer powers, but this is all I really need to convince you that log_3(28) is between 3 and 4.
log_3(28) means the value x such that 3^x=28.
Since 28 is between 27 and 81 in my list above, that means 3^x is between 3^3 and 3^4. This means that x is a value between 3 and 4.
Answer:
$450
Step-by-step explanation:
The sale price is computed from ...
... sale price = original price - discount
where ...
... discount = (original price) × 26%
Putting these together, we get ...
... sale price = (original price) - 0.26×(original price)
... sale price = (original price) × (1 - 0.26) = 0.74×(original price)
Dividing by 0.74, we find ...
... original price = (sale price)/0.74
... $333/0.74 = $450 = original price
