Alice purchased a compass from an online retailer. The cost of the compass was $60.00, and was marked 40% off. Sales tax for the item is 7.5%, plus a shipping fee of $5.99. What is the final price, including discount, tax and shipping?
Answer:
$60.00 * 1.075 * .6 + 5.99 = $44.69
when you have multiple fees and discounts and taxes and whatever else, you should follow the order of all operations. multiplication and division before addition and subtraction, and so on.
Step-by-step explanation:
For discount and sales tax you multiply, and for shipping you just add the fee. We will save shipping for last since it doesn't effect the discount or tax. Meanwhile you could apply the discount and tax in any order.
To apply a discount you take the price and multiply by 1 minus the percent in decimal form. decimal form of a percent is basically the number divided by 100. so 40% = .4 then 1 - .4 = .6
to apply a ttax you multiply 1 plus the percent in decimal form. tax is 7.5% so in decimal form that's .075 then 1 plus the tax is 1.075
so now you multiply 60 * .6 * 1.075 and also remember 60 * .6 * 1.075 = 60 * 1.075 * .6 but the answer is $38.70
Now add the shipping, so 38.70 + 5..99 = $44.69

Alex only keeps ten pence coins and some twenty pence coins in
his coin box. He has a total of 18 coins which amounts to £2.30.
Work out the number of ten pence coins and twenty pence coins
in Alex's coin box.
Answer:
In the box. we have 5 20 pence coins and 13 10 pence coins
Step-by-step explanation:
Let the number of 10 pence coins be x and the number of 20 pence coins be y
The sum of these numbers is 18
Thus;
x + y = 18•••••••(i)
Writing the value in pence only
£2.30 * 100 = 230 pence
Now we have that;
total 10 pence coin amount = 10 * x = 10x
Total 20 pence coin amount = 20 * x = 20y
10x + 20y = 230
x + 2y = 23 •••••••(ii)
from ii;
x = 23-2y
Substitute this into i
23-2y + y = 18
23-18 = 2y-y
y = 5
Recall;
x + y = 18
x + 5 = 18
x = 18-5
x = 13

The half-life of the isotope Osmium-183 is 12 hours. Choose the equation below that gives the remaining mass of Osmium-183 in grams, M.
after n half-lives have elapsed if there was an initial mass of 590 grams before decay. Then, use the equation to determine the mass remaining
after 36 hours have passed
Mn = 590. ()": M3 – 148
D
M, = 590 C4)*-* : My ~ 148
Mn = 590 - ()": Mz - 74
Mi = 590 - (1) * + : Mz - 74
The given equations are incomprehensible, I'm afraid...
You're given that osmium-183 has a half-life of 12 hours, so for some initial mass M₀, the mass after 12 hours is half that:
1/2 M₀ = M₀ exp(12k)
for some decay constant k. Solve for this k :
1/2 = exp(12k)
ln(1/2) = 12k
k = 1/12 ln(1/2) = - ln(2)/12
Now for some starting mass M₀, the mass M remaining after time t is given by
M = M₀ exp(kt )
So if M₀ = 590 g and t = 36 h, plugging these into the equation with the previously determined value of k gives
M = 590 exp(36k) = 73.75
so 73.75 ≈ 74 g of Os-183 are left.
Alternatively, notice that the given time period of 36 hours is simply 3 times the half-life of 12 hours, so 1/2³ = 1/8 of the starting amount of Os-183 is left:
590/8 = 73.75 ≈ 74
What is the solution of the equation?

Suzy is shopping at a book sale.The table show prices for paperback books.
Answer:
6,9
Step-by-step explanation:
Got it right on edg
The ordered pair which is also on the graph is (6, 9).
What is the number pattern?A number pattern is a pattern in a series of numbers that represents the common relationship between the numbers.
Suzy is shopping at a book sale.
We can see from the table that when books( x) is 2 then the value of y is 3.
Similarly, x = 4 then y = 6
then we can say that the value of y is the addition of half of the value of x in itself.
So, according to the number pattern;
if we take x = 6
Then 6 + 3 = 9
y = 9
Thus, The ordered pair which is also on the graph is (6, 9).
