Answer:
$8.75
Step-by-step explanation:
Tiffany allowance is reduced by $1.25 each time she forgets to clean her room
If she forgets to clean her room 7 times this month
Then her allowance is reduced by
= 1.25 × 7
= 8.75
Hence Tifanny allowance is reduced by $8.75
Answer:
104 burgers
Step-by-step explanation:
So there are 64 burgers sold with cheese and the rest were sold without cheese and the ratio is 8:5.
So basicly divide 64 by 8 and you get 8.
Then multiply 8 by 5 and you get 40.
So there were 40 burgers sold without cheese and 64 with cheese.
So in total the answer is 104.
The answer for this question:
y>-1.1
Well, firstly, that equations seems a bit strange. Let's use an equation I know a bit better: a^2 + b^2 = c^2. To clarify, '^2' means 'to the power of 2'. In this equation, 'c' represents the hypotenuse or the longest side of the angle. It is the only side that is diagonal. In this equation, we are given both the height and the length with the height being either 'a' or 'b' and the length being represented by 'c'. Using our formula, we would get this: 16^2 + b^2 = 20^2. To solve for 'b' which is representing our width, we would subtract '16^2' from both sides like so: b^2 = 20^2 - 16^2. From here, solve to get this: b^2 = 144. From here, square root both sides to get b = 12 or width = 12. Plug in your unit of measurement, feet (ft), and you have your answer!
