Answer:
a. Kito has been billed correctly
Step-by-step explanation:
We simply need to check Kito's work to see if his price is accurate.
First, we can add the prices together to find the price before the sales tax is applied: 39.99 + 24.99 + 26.99 = $91.97
We can use this formula to figure out the total cost, C, after the sales tax, t is added:
C = l + (l * (t / 100)), where l = the price before applying the sales tax
C = 91.97 + (91.97 * (6 / 100)) = 97.4882 = $97.49
We know that the total cost lies between the 50 and 100 and that Kito chose the express shipping. Thus we add: 97.49 + 8.20 = $105.69.
If we did not round before, we would still get the same answer when rounding: 97.4882 + 8.20 = 105.6882 = $105.69
Ok, if you say so. Jean took 1/2 hour to complete 3/8 of a math problem.
Answer:
2 hrs and 32 mins
Step-by-step explanation:
Step 1. Because Inez worked more we are going to start by subtracting the the minutes. 23-51= -28.
Step 2. Now we move on to the hours. 7-4= 3. Know we know that the hour time is going to be three. But wait!
Step 3. Because we can't have negative numbers, we need to subtract some more. 60-28= 32. Now I know that my minutes will be 32.
Step 4. But because we used a negative number we have to subtract another hour from our time.
Answer: 2 hrs and 32 mins
Hope this helps!
Answer: C) $480
Step-by-step explanation:
Given: Jose invested $5000 into a fund with an interest rate of 4.8%.
Therefore, Principal amount (P)$5000
Rate of interest = 4.8%
In decimal rate of interest(r)=0.048
Time (t)= 2 years
We know that the simple interest is given by
Hence, the interest after 2 years = $480
Answer:
1808.64 in²
Step-by-step explanation:
We can first convert 9 cm into 24 in using the scale. From there on outwards, we know that the area of a circle is equal to πr², so we just plug in 3.14 for π and 24 in for r. Then, we get 576(3.14) and finally 1808.64 in².
By the way, the scale is wrong. It should be 8 cm = 3 in, not 3 cm = 8 in.
