At the end of the day, Mr. Díaz drains the pool. The equation
y = -50x + 300 can be used to find y, the number of gallons of
water left after draining the pool for x minutes. Graph the
equation. How long does it take to drain the pool? Explain.
Answer: 6 minutes.
Step-by-step explanation: You can use a graphing calculator to see the exact graph, but you're trying to figure out what value of x gives you a y of 0. -50 times 6 is 300, plus 300 equals 0.
The graph of the equation y = -50x + 300 is a straight line, and plotted below. The time it take the pool to drain, according to this equation, is 6 minutes.
How do we make graph of a function?Suppose the considered function whose graph is to be made is f(x)
The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values f(x) are plotted on the vertical axis.
They are together plotted on the point
(x,y) = (x, f(x))
This is why we usually write the functions as:
y = f(x)
For this case, we're specified that:
y = the number of gallons of water left after draining the pool for x minutes.The relationship between x and y given is: y = -50x + 300Take two different values of x, let it be 0 and 1.
Then, the value of y we get is:
Case 1: x = 0:[tex]y = -50x + 300\\y = -50 \times 0 + 300\\y = 300[/tex]
Thus, one point on the equation y = -50x + 300 is (0,300)
Case 2: x = 1:[tex]y = -50x + 300\\y = -50 \times 1 + 300\\y = 300 - 50 = 250[/tex]
Thus, another point on the equation y = -50x + 300 is (1,250)
Plot these points taking x on horizontal and y on vertical axis. Then join those two points by a straight line. This is the graph of the considered equation as equation of type [tex]y = mx +c[/tex] is a straight line's equation and for straight line, two of its points are sufficient to plot it.
The graph is given below.
Since we know that:
y = number of gallons of water left after draining the pool for x minutes,
so when the pool drains of fully, there will be no water left, or y = 0.
Putting y = 0 in the equation y = -50x + 300, we get:
[tex]y = -50x + 300\\0 = -50x + 300\\\\\text{Adding 50x on both the sides}\\\\50x = 300\\\\\text{Dividing both the sides by 50}\\\\x = \dfrac{300}{50}= 6[/tex]
Thus, when y= 0, we get x = 6, so when the fully filled pool is drained for 6 minutes, the whole pool gets drained (for this case).
Thus, the time it take the pool to drain, according to this equation, is 6 minutes. The graph of the equation y = -50x + 300 is given below.

Answer: For 5 pirate ships, you need 55 pirates. For 11 pirate ships, you need 121 pirates.
Step-by-step explanation:
22 (# of pirates) divided by 2 (# of ships) = 11 pirates per ship. Use this knowledge of 11 pirates per ship to find how many pirates you need for different numbers of ships:
11*5= 55 for 5 ships &
11*11= 121 pirates for 11 ships.

Yesterday, Grace drove 38 1/2 miles. She used 1 1/4 gallons of gasoline. What is the unit rate for miles per gallon?
Answer:
The unit rate for miles per gallon is 30 3/5
miles per gallon
Step-by-step explanation:
To get the unit rate for miles per gallon, we simply divide the number of moles by the amount of gallons
Number of miles is 38 1/2 which is 77/2 miles
Number of gallons = 1 1/4 = 5/4
So unit rate will be;
77/2 divided by 5/4
= 77/2 * 4/5 = 154/5 = 30 3/5 miles per gallon

A biker travels the 120 mi from New York , NY to Wilmington, DE in 8 hours. A bus, a truck, and a rider on a horse take the same route as the biker. At what speed does each of them travel if it takes them 2 hours, 2.5 hours, and 18.75 hours respectively to reach Wilmington? Do the speed and the time vary directly or inversely proportional when the same distance is traveled? Explain why.
Answer:
First, remember the relation:
Distance = Speed*Time.
We know that the distance is 120mi.
A) For the biker we know that:
Time = 8hours.
Speed = Distance/Time = 120mi/8h = 15 mi/h.
B) For the bus we know that:
Time = 2 hours.
Speed = Distance/Time = 120mi/2h = 60 mi/h.
C) For the truck we know that:
Time = 2.5 hours.
Speed = Distance/Time = 120mi/2.5h = 48 mi/h.
D) For the rider on a horse we know that:
Time = 18.75 hours.
Speed = Distance/Time = 120mi/18.75h = 6.4 mi/h.
E) The equation for the speed is:
Speed = Distance/Time.
You can see that time is in the denominator, this means that if for a fixed distance, the time increases, then the denominator increases, which would imply that the speed decreases.
Then the speed is inversely proportional to the time when the distance is fixed.

2. Which part of the triangle is always directly
opposite the right angle?
Answer:
So BASically
A triangle has 3 sides
One is the hypotenuese
The other is the Base
and the last one is perpendicular
Step-by-step explanation:directly
opposite the right angle is The HYPOTENUESE
For any triangle, the longest side is always opposite the largest angle. The largest angle of a right triangle is always the 90 degree angle. If you had any larger angle, then the triangle wouldn't be a right triangle and instead it would be obtuse.
In a right triangle, the longest side is given the special name hypotenuse. The other sides of a right triangle are called the legs.

Write an equation that is parallel to y=4/5x+1?
Answer:
y=4/5×
Step-by-step explanation:
its parallel. U just have to leave the slope alone but find a different y intercept.
When parallel lines passes through origin (0,0) the the equation of line parallel to [tex]y=\frac{4}{5}x+1[/tex] is
[tex]y=\frac{4}{5}(x)[/tex]
Given :
Given the equation is [tex]y=\frac{4}{5}x+1[/tex]
the given equation is in the form of y=mx +b
where m is the slope and b is the y intercept
[tex]y=\frac{4}{5}x+1\\slope =\frac{4}{5}[/tex]
when two lines are parallel to each other then the slopes are equal
slope of parallel line = slope of given line
slope of parallel line =[tex]\frac{4}{5}[/tex]
When parallel lines passes through origin (0,0) the the equation of line parallel to [tex]y=\frac{4}{5}x+1[/tex] is
[tex]y-0=\frac{4}{5}(x-0)\\\y=\frac{4}{5}(x)[/tex]

(x+16)°
(4x-5)°
Find the measure of the angle.
I
[tex]4x - 5 = x + 16[/tex]
Subtract the sides of the equation plus 5
[tex]4x = x + 16 + 5[/tex]
[tex]4x = x + 21[/tex]
Subtract the sides of the equation minus x
[tex]3x = 21[/tex]
Divided the sides of the equation by 3
[tex] \frac{3}{3} x = \frac{21}{3} \\ [/tex]
[tex]x = 7[/tex]
So the measure of the angle equals :
[tex]4(7) - 5 = 28 - 5 = 23 [/tex]
