Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
Amount Josh earn each summer = $2700
Rate of simple interest = 4.5%
According to question, he deposits the same amount each year.
First summer, he deposited = $2700
In Second summer, he deposited = $2700×2= $5400
In Third summer, he deposited = $2700 × 3=$8100
At the end of his third summer, his money becomes,
As we know the formula for "Amount" that it becomes at the end of his third summer:
Hence, Option 'B' is correct.
Answer:
Step-by-step explanation:
You must state the "price before tax". Let this be P. Also, you must state the sales tax rate. Let this be r, where r is a decimal fraction.
Then the sales tax is rP, the product of the tax rate and the "price before tax."
The total cost of the item (for which it is sold) is (P + rP)($40).
If P = $40 and the sales tax rate is 7%, then
this total cost is (1 + 0.07)P = 1.07P = $42.80
Your question would be clearer if you wrote it like this: Given that the base price of an item is $40 and that the sales tax rate is 7%, find the total cost of the item with tax. That would be (1 + 0.07)($40), or $42.80.
The sales tax is $42.80 - $40 = $2.80.
Answer:
Step-by-step explanation:
You'll need to share the set of data if you want a precise answer.
But here's how to find the IQR:
1. Arrange the data in ascending (increasing) order
2. Identify the median. This divides the list of data into two parts.
3. Find Q1 and Q3. They are the medians of these two parts.
4 Subtract Q1 from Q3. The result is the IQR that you wanted.
Answer:
$60
Step-by-step explanation:
36/0.6 = 60
60 x 0.6 = 36
I hope that's correct? :)
Answer:
I won't write it in paragraph but use this:
- angle A + angle B + angle C = 180 so when one angle is missing add the other 2 and subtract it to 180, that would be the answer for the missing angle; applies only to triangle (all kinds)
- if its the exterior angle, add them all like the one above but subtract it instead to any shapes or if it is adjacent to a given degree, you can always subtract it to 180 to get the exterior
- if its a different shape, count the sides and subtract it by two then multiply by 180; thats the degree for the total angles of the shape
- if its variable, do the third one (unless you know what it is) add them all like the first one and subtract to the answer in the #3
