yan [13]

Answer:

<h2> 105 tickets</h2>

Step-by-step explanation:

To solve this problem we need to model an equation to represent the situation first.

the goal is to archive $7500 in the even, bearing in mind that there is a cost of $375 fee for rent, we need to put this amount into consideration

let the number of tickets be x

so

75x-375>=7500--------1

Equation 1 above is a good model for the equation

we can now solve for x to determine the number of tickets to be sold to archive the aim

75x-375>=7500--------1

75x>=7500+375

75x>=7875

divide both sides by 75 we have

x>=7875/75

x>=105 tickets

so they must sell a total of 105 tickets and above to meet the target of $7500 with the rent inclusive

laiz [17]

Answer:

<u>The correct answer is C. 5,000</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of fresh meat Joseph eat per week = 11 pounds

2. How many grams of meat does Joseph eat per week?

Let's answer the question this way:

Conversion of pounds to kilograms

Number of kilograms = 11/2.2

Number of kilograms = 5

Conversion of kilograms to grams

Number of grams = 5 * 1,000

Number of grams = 5,000

<u>The correct answer is C. 5,000</u>

Deffense [45]

Answer: Approximately d = 208.72

============================================================

Work Shown:

Make sure your calculator is in radian mode

A quick way to check is to compute cos(pi) and you should get -1

cos(angle) = adjacent/hypotenuse

cos(x) = 200/d

cos(0.29) = 200/d

d*cos(0.29) = 200

d = 200/cos(0.29)

d = 208.715135166392 which is approximate

d = 208.72

I rounded to two decimal places since x is rounded in that manner as well. Round however else you need if your teacher instructs.
