The school band booster club runs a concession stand for home football games. They sell beverages for $1.50 and candy for $1.25. Their goal is to raise $375 for each game.
Write an equation that is a model for the different numbers of beverages and candy that can be sold to meet the goal.
1.25x + y = 375
x + y = 375
1.50x.- 1.25y = 375
1.50x +1.25y = 375
Answer:
1.50x + 1.25y = 375
Step-by-step explanation:
x = beverages
y = candy
1.50x + 1.25y = 375
The equation that can be used to model the different numbers of beverages and candy that can be sold to meet the goal is 1.50x+1.25y=375.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of beverages sold be x, while the number of candies sold is y.
Given that the selling price of a beverage is $1.50, while the selling price of candy is $1.25. Also, the total amount that is needed to be raised is $375. Therefore, the total cost can be written as,
[tex](\$1.50 \times x)+ (\$1.25 \times y) = \$375\\\\1.50x+1.25y=375[/tex]
Hence, the equation that can be used to model the different numbers of beverages and candy that can be sold to meet the goal is 1.50x+1.25y=375.

Element X decays radioactively with a half life of 8 minutes. If there are 480 grams of
Element X, how long, to the nearest tenth of a minute, would it take the element to
decay to 14 grams?
y=a(.5)
Answer:
40.8 minutes
Step-by-step explanation:
Element X decays radioactively with a half life of 8 minutes. If there are 480 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 14 grams?
The formula to find how long it would take which is the time elapsed is given as:
t = t½ × In(Nt/No)/-In2
t = ?
t½ = 8 minutes
Nt = Amount after the time of decay = 14 grams
No = Original Amount of substances = 480 grams
t = 8 × In(14/480)/-In2
t = 40.796285388407 minutes
Approximately to the nearest tenth = 40.8 minutes
Therefore, it would take the element X, 40.8 minutes to decay to 14 grams

Translate the sentence into an inequality five substracted from the product of 8 and a number is at most 25 use the variable x for unknown number
Answer:
8x - 5 ≤ 25
Step-by-step explanation:
Given that the unknown number is x
product of 8 and a number is expressed as 8x
five substracted from the product of 8 and a number is expressed as 8x - 5
Since this expression is at most 25, the inequality sign that you are to use will be ≤ (less than or equal to) since it cannot be greater than 25. Hence the required inequality expression is 8x - 5 ≤ 25

The value of x in the hexagon is 17.
How to find the angle of a hexagon?A hexagon is a polygon with six sides. The sum of angles in a hexagon is 720 degrees.
Therefore, x can be found in the hexagon as follows:
we have to sum the whole angles to get x.
110 + 8x - 1 + 5x + 36 + 116 7x + 19 + 6x - 2 + 110 = 720
combine like terms
110 + 116 - 2 + 36 - 1 + 19 + 8x + 5x + 7x + 6x = 720
278 + 26x = 720
subtract 278 from both sides of the equation
278 + 26x = 720
278 - 278 + 26x = 720 - 278
26x = 442
divide both sides by 26
x = 442 / 26
x = 17

Neil got a hit 9 of the 11 times he batted in the CDNIS softball tournament. Maggie got a hit 18 of the 22 times she batted in the tournament. Did they have the same batting records?
Answer:
YES
Step-by-step explanation:
If 18/22 is expressed in simplest terms. that is if both the numerator and denominator is divided by 2. It gives 9/11
We can determine if they are the same by multiplying both fractions by 100
9/11 x 100 = 81.8
18/22 x 100 = 81,8
they yield the same number, thus the records are the same

Answer:
-79.78 (really stinking cold)
Step-by-step explanation:
Solving the equation will go like this:
5/9(F - 32) = -62.1
multiply both sides by 9 to get rid of the fraction
5 (F - 32) = -558.9
divide both sides by 5
F - 32 = -111.78
add 32 to both sides
F = -79.78
