Answer: 3 = 12 , 4 = 2 , 2 = 22
Step-by-step explanation: Since t represents the number of tickets purchased, we need to plug that into our equation.
d = -10t + 42
d = -10(3) + 42
We know that d is the balance of the bank account, so if we plug in the number of tickets purchased, we will solve to get the balance of the bank account.
d = -10(3) + 42
d = -30 + 42
d = 12
In this equation, If we purchase 3 tickets, the balance of the bank account would be 12 dollars.
Let's do the last 2 equations using d = -10t + 42.
d = -10(4) + 42
d = -40 + 42
d = 2
In this equation, If we purchase 4 tickets, the balance of the bank account would be 2 dollars.
d = -10(2) + 42
d = -20 + 42
d = 22
In this equation, If we purchase 2 tickets, the balance of the bank account would be 22 dollars.

What is perimeter and area of this object?
Answers
Answer:
Step-by-step explanation:
You have a circle with radius r = 3 ft and a 3-by-12 rectangle.
Area of circle = πr² = 9π ft²
Area of rectangle = 3 × 12 = 36 ft²
Total area = 36 + 9π ≈ 64.3 ft²
Perimeter of circle = 2πr = 6π ft
Perimeter of rectangular projections = 18 ft
Total perimeter = 6π +18 ≈ 36.8 ft
Find the perimeter of the semicircle below. Use 3.14 for
pi.
1.6 ft
Answers
Answer:
8.2ft
Step-by-step explanation:
Perimeter of a whole circle = 2*pi*r with radius r
Here we have 1.6ft as the radius so the whole circle's perimeter would be
2 * 3.14 * 1.6 = 10.048
We have half the circle so we half this number to 5.024.
Now we have to add the bottom straight line, which is two radii (two lots of 1.6)
5.024 + 1.6 + 1.6 = 8.224 which is rounded to 8.2ft

how do I find the percent of budget?
Answers
Answer:
First, subtract the budgeted amount from the actual expense. If this expense was over budget, then the result will be positive.
Next, divide that number by the original budgeted amount and then multiply the result by 100 to get the percentage over budget. If your expenses were lower than your budgeted amount, then this number will be negative, describing the percentage under budget.

What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Jenna's profit for selling 38 ornaments is $104.50. Suppose Jenna keeps track of the number of sales (x) and profit (y) on a graph.
Assume that the equation of the graph representing Jenna's profit is -
y = mx + c
Then, it is a basic fact that with 0 sales, $0 profit will will be there. So, the line passes through (0, 0). Hence, the y - intercept [c] = 0. Then -
slope = [m] = (104.5)/38 = 2.75
So, the equation of line would be -
y = 2.75x
Therefore, the equation of the graph representing Jenna's profit is -
y = 2.75x

30 points!!!! a class of 30 students the Ratio of the numbers of boys to girls 7:8
How many girls are there in the class?
Answers
Answer:
16 girls in the class
14 boys in the class
Step-by-step explanation:
Because of the ratio of 7:8, I added 7+8.
7+8= 15
30 (the number of students in the class) divided by 15 (the sum of the ratio)
30/15= 2
I then multiplied 8 from the "girls" part of the ratio by 2 (the quotient of 30/15) and got 16. Then I subtracted 16 from 30 and got 14, which s the number of boys in the class.
