Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

$\cos 90^\circ=0$

As we know that

Sine function and Cosine function are complementary.

So, it becomes ,

$\cos(90^\circ-90^\circ)=0\\\\\implies \sin 0^\circ=0$

Hence, Option 'a' is correct i.e. a. 0, because the angles are complementary.

Elisa is making strawberry shortcake. One serving of strawberry shortcake requires one third cup of strawberries and one shortbr

Kisachek [45]

Given, To make a strawberry shortcake for one person, we need :

▪︎ $\frac{1}{3}$ cup of strawberry

▪︎one shortbread biscuit

Quantity of strawberries Elisa has = 3 cups

Number of shortbread biscuits she has = 12

Number of shortcakes she can make :

$= \tt3 \div \frac{1}{3}$

$= \tt\frac{3 \times 3}{1}$

$\color{plum} =\tt 9 \: people$

Thus, Elisa can serve strawberry shortcakes to 9 people.

With 12 dozen shortbread biscuits she can serve 12 people.

Quantity of strawberries needed to serve 12 people :

$=\tt \frac{1}{3} \times 12$

$=\tt \frac{12}{3}$

$\color{plum} = \tt4 \: cups$

<h3>○=> Therefore :</h3>

▪︎Elisa can serve strawberry shortcakes to <u>9 people</u>.

▪︎Elisa will need <u>4 cups of strawberries</u> if she wants to use all dozen shortbread biscuits.

The expression that represents the total amount that can be raised from selling 50 tickets is -2t + 250 and the total amount that can be raised is $194.

What is total revenue?

Total revenue is the amount of money earned by a company from the sale of its goods and services. In other words, businesses use this metric to determine how well their core revenue-generating operations are performing. Total revenue is directly related to marginal revenue.

Number of tickets that will be sold = 50

Number of student tickets that will be sold = t

Number of adult tickets that will be sold = 50 - t

The total amount of money that can be raised from selling 50 tickets is the sum of the total amount raised from selling student tickets and adult tickets.

Total revenue = total amount raised from selling students tickets + total amount raised from selling adults tickets

Total revenue = [3 x t] + [(50 -t) x $5]

Total revenue = $3t + $250 - 5t

Total revenue = -2t + 250

Total revenue = -2(28) + 250

Total revenue = -56 + 250 = $194

Hence, the expression that represents the total amount that can be raised from selling 50 tickets is -2t + 250, and the total amount that can be raised is $194.
