peter buys 4 1/2 pounds of fertilizer for his front yard every 5 weeks. He uses the same amount every time he gardens. How many kilograms of fertilizer will he buy each year

Answers

I believe the answer is 21.23 kilograms.

Explanation
You take 52 and divide by 5 because you’re trying to figure out for the whole year. Then you take what 52 divided by 5 is and multiply by 4.5 since he buys 4.5 pounds every 5 weeks. Then you convert that number which is 46.8 into kilograms which gives you 21.22812

The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds
600 people. By selling tickets, the members would like to raise $
3,300 every night to cover all expenses. Let d represent the number of adult tickets sold at $
7.50. Let s represent the number of student tickets sold at $
4.50 each. If all
600 seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise exactly $
3,300? At one performance there were
two times as many student tickets sold as adult tickets. If there were
360 tickets sold at that performance, how much below the goal of $
3,300 did ticket sales fall?

Answers

a) At $3,300 for 600 seats, the average price per seat is 3300/600 = $5.50. The mix of tickets that results in that average can be found using an X diagram as shown below. The numbers on the right are the differences along the diagonals. When they are multiplied by 2, they add to 600. This shows that the required sales for revenue of $3,300 are
200 adult tickets
400 student tickets

b) When 3 student tickets are sold for each adult ticket, the average seat price is
(3*$4.50 +7.50)/4 = $5.25
Then the shortfall in revenue is ...
$3,300 -480*$5.25 = $780

PLEASE HELP DUE IN 30 MIN I WILL GIVE BRAINLIEST PLEASE HELP AND DONT SPAM PLEASE HELP IM ALREADY FAILING MATH :-(

Answers

System of equations will be important here. We have two pieces of information: how many tickets were sold, and the total price.

A= adults, S = students

A + S = 155 (# of tickets)
7A + 3S = 645 (total profit)

S = 155 - A , based on the first equation

Now substitute S into the second equation.

7A + 3(155 - A) = 645

7A + 465 - 3A = 645

4A = 180

180/4 = 45 adult tickets sold.

Step-by-step explanation:

Complementary angles are two angles that have measures with a sum of 90°. Angles P and Q are complementary and the measure of angle P is 6° more than twice the measure of angle Q.

Write a system of equations and use substitution to find the measures of angles P and Q.

Input Field 1 of 1

Answers

Answer:

P = 62° Q = 28°

Step-by-step explanation:

Let x = measure of angle Q

then y = measure of angle P

Now x + y = 90 and 2x + 6 = y

Substituting 2x + 6 from the second equation in for y in the first equation, we get x + 2x + 6 = 90 since the two angles are complementary.

3x + 6 = 90

3x = 84

x = 28

y = 2(28) + 6 = 56 + 6 = 62

Check: 28 + 62 = 90
