The number of gallons of water in the bathtub is a function of time. Therefore, it is true.
How to illustrate the graph?
The graph shows a curve that lets you find the number of gallons of water given any value of t betweeh 0 and 30 plus.
Hence, the number of gallons of time indeed is a function of time, in the interval shown by the graph.
The answer is true, because each t value is paired with exactly one number of gallons".

The number of $15 tickets is
Answer:
the answr is 87 jistg ebcaujse
Step-by-step explanation:
3,500 tickets were sold for $15 each and 4,600 tickets were sold for $25 each.
Let x be the number of $15 tickets and y be the number of $25 tickets.
We know that:
x + y = 7,500 (the total number of tickets sold)
15x + 25y = 153,500 (the total amount of money made from ticket sales)
We can use the first equation to express y in terms of x:
y = 7,500 - x
We can substitute this expression of y into the second equation:
15x + 25(7,500 - x) = 153,500
Solving for x:
15x + 25(7,500) - 25x = 153,500
15x + 187500 - 25x = 153,500
-10x = -34,000
x = 3400
Therefore, 3,400 tickets were sold for $15 each and 7,500 - 3,500 = 4000 tickets were sold for $25 each.

a lateral edge of a right prism ïs 6cm and the perimeter of its base is 20cm find area of its lateral surface
The area of a 2D form is the amount of space within its perimeter. The lateral area of the right prism is 120 cm².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Given the perimeter of the base of the right prism is 20 cm, while the lateral height is 6 cm. Therefore, the lateral area of the right prism is,
Lateral Area of Right Prism = 6cm × 20cm = 120cm²

In order for the triangles to be congurent due to ASA, we need to know two pairs of congruent angles and one pair of congruent sides. We have one pair of sides and angles, so we only need another angle pair, therefore eliminating C and D, which are giving sides.

side a = 147side b = 166angle C = 50 degreesUse these facts to find side c
c^2 = a^2 + b^2 - 2*a*b*cos(C)
c^2 = 147^2 + 166^2 - 2*147*166*cos(50)

On a popular television game show, a contestant must choose one of the five envelopes. One envelope contains the grand prize, a car. Find the probability of not choosing a car. Show your solution.
Urgent! Please answer immediately. The answers that are nonsense will be reported.
Answer:
4/5
Step-by-step explanation:
First, we know that we have 5 envelopes. So the denominator of the probability is going to be x/5. We then realize that only one envelope has the car, so the probability of that is 1/5. If we subtract 1/5 from the probability of choosing an envelope (5/5), we get 5/5-1/5=4/5.
