Answer:
1/3 gallons of waterStep-by-step explanation:
If Daniela has 2 1/4 basketball games left to play in a tournament, and she has 3/4 gallon of water left to drink, since she drinks the same amount in each game, we can say;
2 1/4 games = 3/4 gallons
To calculate how much he has to drink in a game, this can be expressed as;
1 game = x gallon
Solve for x;
2 1/4 games = 3/4 gallons
1 game = x gallon
Cross multiply
3/4 = 2 1/4x
3/4 = 9/4 x
9x/4 = 3/4
cross multiply;
9x * 4 = 4*3
36x = 12
x = 12/36
x = 1/3
Hence she can drink 1/3 gallons of water in each game.
According to your graphing calculator what is the approximate solution to the trigonometric inequality tan(x/4)<1/5 over the interval 0<= x<=2pi radians 
0<=x<0.7896
0<=x<0.9799
0<=x<0.9870
0<=x<1.2249
The approximate solution to the trigonometric inequality will be 0<=x<0.7896. Option A is correct.
What is the definition of inequality?Inequality is a sort of equation in which the equal sign is missing. As we will see, inequality is defined as a statement regarding the relative magnitude of two claims.
Given inequality;
tan(x/4)<1/5
x/4 = tan⁻¹(1/5)
0<=x<0.7896
The approximate solution to the trigonometric inequality will be 0<=x<0.7896.
Hence option A is correct.

I please need help with this question. Thank you
Part (A)
The input variable is the shoe size because it is along the horizontal axis, or x axis. It's not clear what the units for the shoe size are, but it's possible the units are in inches.
The output variable is the y value, which in this case is the height. The units for the height is in inches.
====================================================
Part (B)
We have a positive trend. We determine this visually by noting the regression line, or trend line, is going upward as we move from left to right.
Algebraically, the equation for the trend line has a positive slope, which leads to a positive trend.
A positive trend is where x and y increase together. As shoe size goes up, height goes up as well.
While not all the points are on the line, there is a tendency for the points to go uphill as we move from left to right.
As for the strength of the correlation, that part is subjective. If we knew the correlation coefficient r, then we could be more certain; however, we don't know this value. So instead we have to eyeball the given graph and give an estimate. Based on the graph, I'd say there's a moderate positive correlation going on. It's somewhere in the middle of weak and strong positive correlation because the data points are somewhat scattered randomly, but they trend upward nonetheless.
====================================================
Part (C)
The rate of change is the slope. The slope is the coefficient of the independent variable x. In this problem, the slope is 1.728
So the rate of change is 1.728 inches per shoe size.
In other words, as the shoe size increases by 1 unit (1 inch perhaps?), the height will increase by roughly 1.728 inches.
---------------------------------------------------------
Extra info:
The equation
Height = 51.46 + 1.728(Shoe Size)
is the same as
y = 51.46 + 1.728x
where x is the shoe size and y is the height
We can rearrange that into
y = 1.728x + 51.46
So that it matches with the familiar y = mx+b slope intercept form. This is optional.

Answer:
2x + 5y = -4
Step-by-step explanation:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
========================================================
Explanation:
Let's use point slope form to get
y - y1 = m(x - x1)
y - y1 = -4(x - x1) .... plug in the given slope m = -4
y - 5 = -4(x - 2) .... plug in the given point (x1,y1) = (2,5)
Now we isolate y
y - 5 = -4(x - 2)
y - 5 = -4x + 8
y = -4x + 8 + 5
y = -4x + 13
This equation is in slope intercept form y = mx+b
m = -4 is the slope
b = 13 is the y intercept
To get this into standard form, we add 4x to both sides so that the x and y terms are on the left side
y = -4x+13
y+4x = 13
4x + y = 13 is the final answer
This is in standard form Ax+By = C where
A = 4
B = 1
C = 13
--------------------------
Let's check the answer. Plug in (x,y) = (2,5) to find that...
4x+y = 13
4*2 + 5 = 13
8 + 5 = 13
13 = 13
We get the same thing on both sides, so the last equation is true. This means the first equation is true when (x,y) = (2,5). This confirms the point (2,5) is on the line and helps confirm the answer.

Wingspans of adult horses have approximate normal distribution with mean 125 cm and standard deviation 12 cm. What are the rst and third quartiles of the wingspans
Answer:
The first and third quartile of the wingspans are 116.9 cm and 133.1 cm respectively.
Step-by-step explanation:
The first and third quartile of a normal distribution are:
[tex]Q_{1}=\mu-0.675\sigma\\\\Q_{3}=\mu+0.675\sigma[/tex]
The information provided is as follows:
[tex]\mu=125\\\sigma=12[/tex]
Compute the first and third quartile of the wingspans as follows:
[tex]Q_{1}=\mu-0.675\sigma=125-(0.675\times 12)=116.9\\\\Q_{3}=\mu+0.675\sigma=125+(0.675\times 12)=133.1[/tex]
Thus, the first and third quartile of the wingspans are 116.9 cm and 133.1 cm respectively.

At one time the price of gasoline was $1.279 a gallon. Then the price
increased 130% of the original price. What was the cost of the increase in
the price of gasoline?
Answer:
1.6627 (money wise, $1.66)
Step-by-step explanation:
Since its 130%, you know there was already a whole increase. So first you would do 1.279 + 1.279, which would give you 2.558. Then you need to calculate 30% of 1.279 for the rest of the increase. That gives you 0.3837 Add 2.558 and 0.3837 together, which would give you 2.9417. To get the INCREASE, you would have to subtract the new total from the original price, so 2.9417 - 1.279. This would give you 1.6627.
There were 935 offenses in 2000 and 2448 offenses in 2019. What is the percentage increase?
Answer:
Approximately 262%
Step-by-step explanation:
To find the percentage increase divide the new amount of offenses by the old amount of offenses:
2448/935 = 2.618
2.618 rounds to 2.62. Convert 2.62 into a percentage: 262%
The percentage increase between the amount of offenses in 2000 and the amount of offenses in 2019 is approximately 262%.

Two people climbed to the roof of a building. The old person walked up a gentle ramp. The young person climbed up a steep spiral staircase. Which person did more work? Explain.
Answer:
both people actually did the same work
Step-by-step explanation:
Work = Force × Distance
The person that climbed the steep spiral staircase used more force but covered a shorter distance. On the other hand, the person that walked up a gentle ramp used less force but covered a longer distance. Since both people reached the same height, the force against gravity was the same.
Based on the information given, the person that will do more work is the young person.
From the information given, it was stated that two people climbed to the roof of a building. The old person walked up a gentle ramp while the young person climbed up a steep spiral staircase.
In this case, since the young person climbed up a steep spiral staircase, the young person will do more work.
