One cotton candy at the rodeo cost $5.25. When 4 friends purchases cotton candy, the expression 5.25(4) can be used to determine the total cost. What other expression can be used to determine the total cost?
The other expression for this scenario is 5.25 + 5.25 + 5.25 + 5.25
How to determine the other expression?From the question, we have the following parameters that can be used in our computation:
Cost of cotton candy = $5.25
Number of friends = 4
So, the expression is given as
Expression = 5.25(4)
Express 4 as 1 + 1 + 1 + 1
So, we have the following representation
Expression = 5.25(1 + 1 + 1 + 1)
Open the bracket
Expression = 5.25 + 5.25 + 5.25 + 5.25
Hence, the other expression is 5.25 + 5.25 + 5.25 + 5.25

Jacob is buying pizza dough at the store to make pizzas for his family.
For every 15 pizza doughs he buys, he pays $20.
What is the price per pizza dough?
Answer: $1.33
This can be worked out as a simple algebra problem: 15x=20, x being 1 pizza dough. In order to find the value of one pizza dough (x) you need to isolate it. To do that, divide 15 from both sides and you'll be left with x=1.33
15x=20
/15 /15
x=1.33
13. Suppose you live in a state that collects 18.2c excise tax on a gallonof gasoline. If you buy 18.5 gallons of gasoline, how much state excise taxis collected?a, $3.06b 83.37$2.99C
The excise tax on 1 gallon of gasoline = 18.2 cents
You will buy 18.5 gallons
We need to find the excise tax you should pay
At first let us change the cent to dollar
1 cent = 1/100 dollars
18.2 cents = 18.2 * 1/100 = 0.182 dollars
Now you will buy 18.5 gallons
You will pay = 18.5 * 0.182 = 3.367 Dollars
The state excise tax = $3.367
Round the number to the nearest cent, then it will be $3.37

If ED is the midsegment of ABC, which of the following statements are necessarily true?
If ED is the midsegment of triangle ABC, then that means that the points E and D are the midpoints of segments AC and AB since the midsegment is found by joining the midpoints of a triangle. Since E and D are midpoints then:
[tex]AE\cong EC[/tex]Also, by the midsegments theorem we have:

how many ways can this be done?
The number of ways the customer can select 4 appetizers , 4 main course and 4 desserts for a banquet is 220500 ways .
In the question,
it is given that ,
number of appetizers that catering service can offer = 6
number of main courses that catering service can offer = 8
number of desserts that catering service can offer = 4 ,
The number of ways 4 appetizers can be selected out of 6 = ⁶C₄
number of ways 4 main courses can be selected out of 8 = ⁸C₄
number of ways 4 desserts can be selected out of 10 = ¹⁰C₄
So , total number of ways = ⁶C₄ × ⁸C₄ × ¹⁰C₄
= 15 × 70 × 210
= 1050 × 210
= 220500 ways

Given,
In the question:
A motorboat moves across a lake as a constant speed. when it begins, it is 50 km from the shore
After 9 minutes, it is 14 km from the shore.
So, The rate of change =
= [tex]\frac{Final Distance - initial distance}{time} \\\\\frac{14-50}{9} = -4[/tex]
Negative sign shows that there is decrease in distance per minute
The rate of change of distance is 4 km / minutes
General equation : y = mx+ c
Where m is the slope and c is the constant
Substitute the values in the equation :
y= -4x +50
Where y is the final distance and x is the minutes
So, Option C is true
Hence, The function describes the motorboat's distance from the shore

Answers:
We see that ∠2 and ∠3 are corresponding angles
And since the lines u and v are parallel, ∠2 and ∠3 are congruent.
So, m∠3 = 150
We see that ∠1 and ∠2 are vertically opposite angles
Thus, ∠1 and ∠2 are congruent
So, m∠1 = 150
The relationship between ∠1 and ∠3 is an example of the following rule
When parallel lines are cut by a transversal, alternate interior angles are congruent.
Explanation:
The angles formed by two parallel lines and a transversal that are on the same side of the transversal and in the same position from the parallel lines are called corresponding angles. These angles have the same measure so they are also congruent.
So, we can fill the first part as:
We see that ∠2 and ∠3 are corresponding angles
And since the lines u and v are parallel, ∠2 and ∠3 are congruent.
So, m∠3 = 150
On the other hand, two opposite angles formed by two lines that cross are called vertically opposite. So, these angles have the same measure.
So, we can fill the second part as:
We see that ∠1 and ∠2 are vertically opposite angles
Thus, ∠1 and ∠2 are congruent
So, m∠1 = 150
Finally, we can fill the third part as:
The relationship between ∠1 and ∠3 is an example of the following rule
When parallel lines are cut by a transversal, alternate interior angles are congruent.
Because alternate interior angles are the angles that are inside the parallel line and on opposite sides of the transversal.

-6 = 3х - бу4х = 4 + БуSolving systems of equations using substitution method
-6 = 3x - 6y
4x = 4 + 5y
ok
x = (4 + 5y)/4
Substitution
-6 = 3[(4 + 5y)/4] - 6y
-6 = [12 + 15y]/4 - 6y
-6 + 6y = [12 + 15y]/4
-24 + 24y = 12 + 15y
24y - 15y = 12 + 24
9y = 36
y = 36/9
y = 4
x = (4 + 5(4))/4
x = [4 + 20)/4
x = 24/4
x = 6
Solution x = 6, y = 4

Answer:
length = 12 miles
width = 6 miles
Step-by-step explanation:
Framing algebraic expression and solving:length = x miles
width = (x - 6) miles
Area of rectangle = 72 square miles
length * width = 72
x * (x - 6) = 72
x*x - 6*x = 72
x² - 6x - 72 = 0
Sum = -6
Product = -72
Factors = 6 , (-12) { 6 + (-12) = -6 and 6*(-12) =-72 }
Rewrite the middle term using the factors.
x² + 6x - 12x - 72 = 0
x(x + 6) -12(x + 6) =0
(x + 6)(x - 12) = 0
{x + 6 = 0 is rejected as length will not have negative value}
x - 12 = 0
