The ordered pairs that shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after can starts dispensing water: {(1, 7.8), (2, 7.6), (3, 7.4)}
For given question,
A watering can dispenses water at the rate of 0.20 gallon per minute.
The original volume of water in the can was 8 gallons.
We need to find the ordered pairs that shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after can starts dispensing water.
The ordered pair is of the form (x, y) means the first coordinate is time in minutes and the second coordinate is the volume of water in the can in gallons.
Initially, for x = 0 minutes, y = 8 gallons
After 1 minute, the amount of water in can is 8.0 - 0.20 = 7.8 gallons.
So, the ordered pair of the form (time, volume of water) are: {(1, 7.8), (2, 7.6), (3, 7.4)}
Therefore, the ordered pairs that shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after can starts dispensing water: {(1, 7.8), (2, 7.6), (3, 7.4)}

What is the ratio for sin A?
Answers
According to the given triangle the value of sin A = 4/5
In a right-angled triangle, the sin of an angle is equal to the ratio of the opposing side to the hypotenuse according to the sin theta formula.
Sin A = Opposite angle / hypotenuse= 4/5
There are about six trigonometric ratios—sine, cosine, tangent, cosecant, secant, and cotangent—which describe the many configurations that can be made in a right-angled triangle.
Trigonometry can only be used to solve a side of a right-angled triangle when the lengths of the other two sides and the angle of a side are already known. Before utilizing algebra to determine the value for the unknown side, one must first select a ratio that includes both the unknown and the given sides.
We are aware that the angle-length relationship in right-angled triangles will be covered in trigonometry.

Given that,
In the picture there is a triangle with ABC angles.
Sides AB=5, BC=3, CA=4
Trigonometric ratios, which contain the values of all trigonometric functions, are based on the ratio of sides of a right-angled triangle. The ratios of a right-angled triangle's sides with regard to a certain acute angle are known as its trigonometric ratios.
The right triangle's three sides are as follows:
Hypotenuse (the longest side)
Perpendicular (opposite side to the angle)
Base (Adjacent side to the angle)
According to the sin theta formula, the sin of an angle in a right-angled triangle is equal to the ratio of the opposite side to the hypotenuse.
Sin A = Opposite side / hypotenuse
SinA=3/5
Therefore, SinA=3/5.

Ama is sliding down the Super Mega Ultra Slide at a local amusement park. She slides at a rate of 8 m/s downward, and after 3 seconds is 5 m off of the ground. How many seconds will it take her to slide to the ground from the top? Round your answer to the nearest tenth. *
Answers
Answer:
3.0625 seconds
Step-by-step explanation:
From the question,
✓She slides at a rate of 8 m/s downward
✓after 3 seconds is 5 m off of the ground
We can calculate the the number of seconds she will use to get to the ground by
Velocity= distance/time
Time= distance/ velocity
=5/8 seconds
=0.625seconds
To know how many seconds it will take her to slide to the ground from the top can be calculated as
( 3seconds + 0.625 seconds)
= 3.0625 seconds

Answers
Answer:
x = 5Step-by-step explanation:
The sum of two complementary angle is 90 degrees. Given the following complementary angles;
<1 = 6x + 5
<2 = 8x + 15
<1 + <2 = 90 (complementary angles)
6x + 5 + 8x + 15 = 90
14x + 20 = 90
14x = 90-20
14x = 70
x = 70/14
x = 5
Hence the measure of x is 5

Answers
Answer:
C. The interquartile range (IQR) for the Wolverines, 30, is less than the IQR for the Panthers, 40.
Step-by-step explanation:
The interquartile Range (IQR) of a data describes or measures how spread out the data values are.
Thus, IQR = Q3 - Q1. which is the range of the rectangular box in the box plot given.
Thus,
IQR for the Wolverines = 85 - 55 = 30
IQR for the Panthers = 90 - 50 = 40
Therefore, comparing their spreads, the most appropriate statement is:
C. The interquartile range (IQR) for the Wolverines, 30, is less than the IQR for the Panthers, 40.

Answer:
y = 4
or (0, 4)
Step-by-step explanation:
intersecting the y-axis is basically when x is equal to 0.
1.5(0) +4.5y = 18
y = 4
So your y-intersect is (0, 4) and thats when it intersects the y-axis.
If y varies directly with x, and y = 15 when x = 20, find y when x = 75.

Fwd:The hardware store is having a 15% off sale on lawn mowers this weekend. If x is the original price of a lawn mower, what will be the final sales price, excluding tax? Select two that apply. (0.15 + x) , x - 0.15 , 0.15x, (x - 0.15x) , x(1.00 - 0.15)
Answers
Answer:
(x - 0.15x) and x(1.00 - 0.15)Step-by-step explanation:
Let x be the original price of a lawn mower,
If the hardware store is having a 15% off sale on lawn mowers this weekend, the amount discounted is expressed as;
= 15 % of x
= 0.15 of x
= 0.15x
Final sales price = Original price - discounted price;
Final sales price = x - 0.15x
Factor out x;
x - 0.15x = x(1 - 0.15)
Hence the correct equations are (x - 0.15x) and x(1.00 - 0.15)
