Answer:the number of cupcakes that Sue purchased is 12
Step-by-step explanation:
Let x represent the number of cupcakes that Sue purchased at the bakery.
Let y represent the number of cookies that Sue purchased at the bakery.
She needs to serve 36 people. This means she would purchase a total of 36 people. Therefore,
x + y = 36
Cupcakes cost $2.50 each, cookies cost $1.00 each. She spends $54.00. This means that
2.5x + y = 54 - - - - - - - - - 1
Substituting x = 36 - y into equation 1, it becomes
2.5(36 - y) + y = 54
90 - 2.5y + y = 54
- 2.5y + y = 54 - 90
- 1.5y = - 36
y = - 36/ - 1.5
y = =24
x = 36 - y = 36 - 24 = 12

It's exactly in between the steep slope and the flat line and the steep line's slope is x or 1x.
Answer:
Step-by-step explanation:
The given arc length relation requires the central angle be expressed in radians. There are π radians in 180°.
s = rθ = (5 in)(170°×π/180°) = 85π/18 in ≈ 14.84 in
Since 158 minus 113 is 45, Manny only has to read 45 pages. If Manny reads nine pages a day, you have to divide 45 by 9, which leaves you with 5. It will take Manny 5 days to finish the book.
Answer:
Neither options one or two is true
Step-by-step explanation:
When we test a statistical hypothesis, we must specify a level of significance. It is this level of significance that presents the maximum probability at which we are willing to risk committing a type one error.
Therefore, it is independent of any other level of significance used.
Hence, we conclude that neither options one or two is true.
