pychu [463]

Sid and Libby are planning to sell pies at a local fair.
=> $200 to rent a table at the fair.
=> $3.00 per pie costs for ingredients, other supplies, baking, and packaging
They plan to sell the pies for $8 each.
Let's find out how many pies will they be selling inorder to gain profit
=> 200 + 3.00(n) = 8(n), where n is the number of pie.
Let's try 40
=> 200 + 3(40) = 8 (40)
=> 320 = 320
=> 200 + 3(41) = 8 (41)
=> 323 = 328
Thus, in their 41st pie, they will get a profit

If 180°<θ<270°, and sin⁡θ=−3/4, what is the value of sin(−θ)?

Oxana [17]

Answer:

$sin(-\theta)=\frac{3}{4}$

Step-by-step explanation:

Given:

180°<θ<270° and $sin(\theta)=-\frac{3}{4}$

We know for any angle $\theta$ ,

$sin(-\theta)=-sin(\theta)$

∴ $sin(-\theta)=-(-\frac{3}{4})=\frac{3}{4}$

Nataliya [291]

The U.S RDA for protein is 46g for girl

If a piece of fried chicken contains 23g

To find the pieces of chicken she is to eat to satisfy the U.S RDA requirement,

The number of pieces of chicken is

$\text{Number of pieces}=\frac{U.S.\text{ RDA g protein required for a girl}}{g\text{ of protein in a piece of chicken}}$

The number of pieces of chicken is

$\begin{gathered} \text{Number of pieces of chicken}=\frac{46}{23}=2\text{ pieces of chicken} \\ \text{Number of pieces of chicken}=2\text{ pieces of chicken} \end{gathered}$

Hence, the right option is B
