Find 10% of 40 to find the amount of the tax:
Convert 10% to a decimal
Multiply:
So the amount of the tax is $4. Just add this to the purchase amount to find the total amount he paid:
So the total amount he paid was $44.
Answer:
Account balance is not proportional to the number of weeks.
Step-by-step explanation:
Initially Adrian's saving account balance was = $28
He deposits $15 in his account each week.
If we denote week with a variable 'x' then after 'x' weeks total amount in is account = $15x
So, total amount in his account after 'x' week will be;
y = 15x + 28
It's a linear equation representing total amount after 'x' weeks with a constant growth rate of 15 and initial amount 28.
In other words equation is in the form of y = mx +b.
This equation doesn't show the proportional relation because equation in the form of y = kx represents the relation of proportionality only.
Answer:
x y
0 28
1 24
2 20
3 16
4 12
5 8
6 4
7 0
8 -4
9 -8
10 -12
Step-by-step explanation:
Not sure how many you needed, but I graphed it out here is the table from 1-10 on it.
Answer: H, 28.26
Step-by-step explanation:
Circle formula: A = πr^2
Diameter = 2r
π = 3.14 (Rounded)
1/2 of 6mm is 3mm.
3π^2 = 28.26 (I rounded)
So the correct answer is H.
I hope this helped!
