Liam works at a zoo. He was looking at some data showing the masses of their 555 African elephants. The mean mass of the elephan

ts was 3{,}800\,{\text{kg}}3,800kg3, comma, 800, start text, k, g, end text, and the median mass was 3{,}600\,{\text{kg}}3,600kg3, comma, 600, start text, k, g, end text. The smallest elephant, named Lola, weighed 2{,}700\,{\text{kg}}2,700kg2, comma, 700, start text, k, g, end text. Lola then got very sick and lost weight until her mass reached 1{,}800\,{\text{kg}}1,800kg1, comma, 800, start text, k, g, end text. How will Lola's mass decreasing affect the mean and median? Choose 1 answer: Choose 1 answer: (Choice A) A Both the mean and median will decrease. (Choice B) B The median will decrease, and the mean will stay the same. (Choice C) C The mean will decrease, and the median will stay the same. (Choice D) D The mean will decrease, and the median will increase.

Two movie tickets and 3 snacks are $24. Three movies tickets and 4 snacks are $35. How much is a movie ticket and how much is a
Vsevolod [243]

Answer: A movie ticket is $9 while a snack is $2

Step-by-step explanation: We shall let a movie ticket be m while a snack is s. So, from the clues given, if two movie tickets and three snacks cost $24, we can write it as the following expression;

2m + 3s = 24

Also if three movie tickets and four snacks cost $35, we can as well write another expression as follows;

3m + 4s = 35.

Now we have a pair of simultaneous equations which are

2m + 3s = 24 ----------(1)

3m + 4s = 35 ----------(2)

We shall solve this by using the elimination method, since none of the variables has a coefficient of 1. We'll start by multiplying equation (1) by 3 and multiplying equation (2) by 2 (so as to eliminate the m variable)

2m + 3s = 24 -------- x3

3m + 4s = 35 ---------x2

We now arrive at the following

6m + 9s = 72--------(3)

6m + 8s = 70--------(4)

Subtract equation (4) from equation (3) and we arrive at

s = 2

Having determined that s equals 2 we can now substitute for the value of a into equation (1)

2m + 3s = 24

2m + 3(2) = 24

2m + 6 = 24

Subtract 6 from both sides of the equation

2m + 6 - 6 = 24 - 6

2m = 18

Divide both sides of the equation by 2

m= 9

Therefore one movie ticket costs $9 while one snack costs $2

The width of a rectangle is the length minus 2 units. The area of the rectangle is 35 units. What is the width, in units, of the
Andrews [41]

Answer: width = 5 units

Step-by-step explanation:

Let L represent the length of the rectangle.

The width of a rectangle is the length minus 2 units. It means that the width of the rectangle is (L - 2) units.

The formula for determining the area of a rectangle is expressed as

Area = length × width

The area of the rectangle is 35 units. It means that

L(L - 2) = 35

L² - 2L = 35

L² - 2L - 35 = 0

L² + 5L - 7L - 35 = 0

L(L + 5) - 7(L + 5) = 0

L - 7 = 0 or L + 5 = 0

L = 7 or L = - 5

Since the length cannot be negative, then

L = 7 units

Width = 7 - 2 = 5 units
