Both the Math Club and the Spanish Club have a pizza party at the end of the year. The Math Club has 16 members and the sponsor gives each member 1/4 of a pizza at the party. The Spanish Club has 18 members and their sponsor gives each member 1/3 of a pizza at their party. Which statement best represents which club buys more pizzas?
The Spanish Club buys 2 more pizzas than the Math Club.
The Spanish Club buys 10 more pizzas than the Math Club.
The Math Club buys 10 more pizzas than the Spanish Club.
The Math Club buys 2 more pizzas than the Spanish Club.
Answer:
The Spanish Club buys 2 more pizzas than the Math Club.
Step-by-step explanation:
The Spanish club has 6 pizzas (18/3) and the math club has 4 pizzas (16/4 = 4), so if we subtract the two the Spanish club has 2 more pizzas than the math club
Answer:
The Spanish club buys 2 more pizzas than the Math club
Step-by-step explanation:
Math club: 1/4 of pizza per 1 person (16 people)
1/4 = .25
.25 * 16 = 4 (They have to buy 4 pizzas)
Spanish Club: 1/3 of pizza per 1 person (18 people)
1/3 = .33
.33 * 18 = 5.94 ((Rounded = 6)They have to buy 6 pizzas)
Who buys more?
Spanish club: 6
Math club : 4

The required value of the given expression is 38 when substituting the values of w = 2, x = 5, y = 8, and z = 3.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
The expression is given in the question following as:
x² + 2y ÷ 2w + 3z
We have to determine the value of the given expression for w = 2, x = 5, y = 8, and z = 3.
As per the given question, we have
⇒ x² + 2y ÷ 2w + 3z ....(i)
Substitute the values of w = 2, x = 5, y = 8, and z = 3 in the given expression,
⇒ (5)² + 2(8) ÷ 2(2) + 3(3)
⇒ 25 + 16 / 4 + 9
Apply the division operation,
⇒ 25 + 4 + 9
Apply the addition operation, and we get
⇒ 38
Therefore, the required value of the given expression is 38.

In her science classroom Jane noticed that the lengths (in inches) and the weights (in ounces) of the class's pet snakes were directly related by the equation y = kx, where x is the length and y is the weight. Use the information in the table to find k, the constant of proportionality?A.25.0 B.27.5 C.30.0 D.32.5
Answer=30
Use one of the ordered pairs that are given to find the value of 'k', the CONSTANT of variation. This number will not change, hence the word 'constant'.
15 = k*6; dividing both sides by 6 we get k = 2.5; The equation used for the table is y = 2.5x
You can find any value now by using this formula.
y = 2.5*12
y = 30
hope this helps and have a great day:)

Answer:
9. Y=4x 10. Y=0.5x
Step-by-step explanation:
9. The dependent or in other words Y is inches and independent is x in this case Y is dependent so it denpends on x since the inches rely on how much bracelts there are it means inches is y and bracelts is x. Then we do 76 divided by 19 or you can do 36 divded by 9 and both of those give us 4 which is 4 inches per a bracelet and our equation would be Y=kx or in this case Y=4x. You can check if its correct by subtituting x for 9 and if it equals 36 it means its correct. You can also do times 19 and if it equals 76 its correct.
10. Same proccess our x is gallons and our y is hours we can choose either one 3 divided by 6 which is 0.5 or 5.5 divided by 11 which also gives us 0.5 this proves its proporitonal and our equation would be Y=0.5 x. you can check by subtituing x for 6 or x for 11.
