Answer:
Both cases will give the same price
Step-by-step explanation:
The total purchase that Joshua do will be:
2* $10.98 + 1 * $11.50 + 2* $15.99 = $65.44
Let's compare the price for both scenario
1. If the tax added before discount
taxed price $65.44 * (100+6.5)% =$69.6936
discounted price= $69.6936* (100-20)%= $55.75488
2. If the tax added after the discount
discounted price= $65.44 * (100-20)%= $52.352
taxed price $52.352 * (100+6.5%) = 55.75488
Both prices will be the same since the operation in this calculation is only multiplication.
Right away, mode is not applicable because mode entails the repetition of the same number. No numbers are repeated here.
To find median, you must put the numbers in numerical order. You should get
111, 114, 121, 179, 216, 220, 234, 246
Next, find the middle. In this case, the middle is split between 179 and 216. To find the median, add 179 and 216 then divide by two. You should get 197.5.
To find the mean, add all the numbers then divide by the number of numbers present (in this case there are 8 numbers). You should get 180.125.
Because the median and mean are off, it is safe to say A is the correct choice.
Answer:
Your answer is drum roll please...... D!
Step-by-step explanation:
3(4+9)
12+27
D. (3x4) + (3x9)
12 + 27
Now hand me my money
The terms 9r^2 and 6r^2 are like terms. We add the numbers to the left of the "r^2" to get 9+6 = 15.
So 9r^2+6r^2 becomes 15r^2
The r^2 stays the same. We do not say something like r^2+r^2 = r^4. You might be thinking of r^2 * r^2 = r^(2+2) = r^4
When it comes to adding like terms, we keep the variables the same.
The other pair of like terms are 3r and 2r, so they add to 3r+2r = 5r
--------------------------------------------------------------------------------------------
Overall,
(9r^2+3r+6)+(6r^2+2r) = (9r^2+6r^2)+(3r+2r)+6
(9r^2+3r+6)+(6r^2+2r) = 15r^2+5r+6
Answer:
(-4.5, 4.25) The first one.
Step-by-step explanation:
Plug in -4.5 in for x and 4.25 for y in BOTH problems. When you plug them in and they both work out for BOTH problems then its the answer.
