Answer:
$1.53
Step-by-step explanation:
Sales Tax Rate = 8.25%
Book Sales Cost = $18.50
Book Sales Tax = 8.25% x $18.50
= 8.25/100 x $18.50
= 0.0825 x $18.50
Book Sales Tax = $1.53
4d = 24 would be the right equation. To double check you would divide both sides by 4 (the number of legs) to find the amount of dogs.
Answer:
8 cookies left to be baked
Step-by-step explanation:
<u>Len</u>
Len bakes 1/3 of 30 cookies
To find 1/3 of 30, divide 30 by 3 then multiply by 1:

Therefore, Len bakes 10 cookies
<u>Sallesh</u>
Sallesh bakes 2/5 of 30 cookies
To find 2/5 of 30, divide 30 by 5 then multiply by 2:

Therefore, Sallesh bakes 12 cookies
<u>Cookies left to bake</u>
To calculate how many cookies are left to bake, subtract the found number of cookies Len and Sallesh have baked from 30:
30 - 10 - 12 = 8
So there are 8 cookies left to be baked.
<u>Solution for question 5:</u>
f(x) = 4x - 8
To find f^-1(x) write it as an equation:
y = 4x - 8
Then take x to left and y to right;
x = 4y - 8
Then solve for y;
y = (x + 8)/4 = x/4 + 2
Your y is the inverse of f(x) = 4x - 8
f^-1(x) = x/4 + 2
Answer:
140
I am not completely sure but what i did was
56/? = 40/100
56*100
