At the nearest wholesale store, 3 bags of cereal cost $21.75. Which equation represents the proportional relationship?
The cost of the 5 bags using proportionality method is: $36.25
What is proportionality?
In mathematics, the term proportionality can be defined by considering a two quantities in constant ratio. And the two quantities can be recognized as the variable y and x. Where, the variable y is defined as directly proportionate to the changes in the variable x which is based on its constant ratio.
According to the question, the given data states that 5 bags will cost $36.25.
By using proportionality method to solve the given statement. Put the price over the number of bags
21.75 x
---------- = ---------
3 bags 5 bags
Using cross products defined in standard mathematics,
21.75 * 5 = 3x
108.75 = 3x
Divide each side by 3
108.75/3 = 3x/3
36.25 =x
5 bags will cost 36.25

Given that,
base salary = b = 5000$
Comission rate = 6% = 0.06
Let's say, the sales are = x
As given in the question, he receives 6% commission on all sales over $8000.
Hence, the commissionable amount is (x - 8000) '.' x - 8000 shows the amount greater than 8000, which receives a commission.
hence, gross income will be
base salary + commission * (commisonable amount)
=> 5000 + 0.06 * (x - 8000)
how can i find x and y in a triangle?
Using the sine formula;
sin 60 / x = sin 90 / 16
cross-multiply
x sin 90 = 16 sin 60
Divide both-side of the equation by sin 90
x = 16 sin 60 /sin 90
x= 13.86
To find y, we can simply use the Pythagoras theorem
opp² + adj² = hyp²
13.86² + y² = 16²
192.0996 + y² =256
subtract 192.0996 from both-side of the equation
y² = 256 - 192.0996
y² = 63.9004
Take the square root of both-side

You have to perform two transformations the first one is a 180º rotation with respect to the origin r(180º,O) and the second one is a translation of one unit left and 5 units up T(-1,5)
Given point A(8,-6)
To make a 180º rotation you have to invert the signs of both coordinates, following the rule:
[tex](x,y)\to(-x,-y)[/tex]For point A, the rotation is the following:
[tex]A(8,-6)\to A^{\prime}(-8,--6)=(-8,6)[/tex]Once you rotate the point, you have to perform the translation T(-1,5). The rule for the translation can be expressed as follows

Speed is calculated by the equation S = d/t, where S = speed, d = distance, and t = time travelled. For what amount of time (in hours) did a car travel if its speed was 75 miles per hour and it travelled a distance of 187.5 miles?
We get from the question the following equation:
S = d/t
We have the following informations:
Speed(S) = 75 miles /h
Distance(d) = 187.5 miles
If you plug those informations into the formula, you'll get the following:
75 miles/h = 185.5 miles/ t
Now, you just have to solve for "t". If you invert the equation, you'll get(I'm going to omit the units, to make it clearer, but don't forget about them!)
1/75 = t / 185.5
If you multiply both sides by 185.5, you'll get
185.5/75 = t
Solving this calculation, we get the final solution!
t = 185.5/75 hours = 2.47 hours

Answer
The solution is
-3 < x < 3
Explanation
To solve an expression with the absolute value symbol. we obtain two solutions for it.
We first solve when the other side of the equation to the absolute value symbol has positive sign.
Then, we obtain another solution by setting that other side (the right-hand side) to negative. For equations involving inequality signs, the second solution usually changes the inequality sign.
| 2x + 3 | < x + 6
First solution
2x + 3 < x + 6
2x - x < 6 - 3
x < 3
Second solution
2x + 3 > -(x + 6)
2x + 3 > -x - 6
2x + x > -6 - 3
3x > -9
Divide both sides by 3
(3x/3) > (-9/3)
x > -3
So, the solution written together,
x > -3 and x < 3
together, it is
-3 < x < 3

To divide the 1/4 of a pound into two equal parts, it is necessary to divide 1/4 by 2, as follow:
(1/4)/2
if 2 is written as 2/1, the previous quotient can be written as a product:
(1/4) (1/2) = 1/8

Ronny is selling coffee mugs for $4.00. So far, he has earned $344.00. Ronny needs to earn more than $392.00 in order to meet his sales goal. How many more coffee mugs, x, does Ronny need to sell in order to reach his sales goal?
Answer:
25 more cups
Step-by-step explanation:
1. You need more than $636.00, but you already have $492.00. To find the needed amount of cups needed to sell, you need to find the difference of the two prices first. In other words, you need to subtract the total needed by the amount already raised.
2. You can get the equation, 636 - 492 = 144
3. Now that you have the amount needed, you can divide the number that you got (144) by 6. You divide it by 6 because that is the amount each cup costs.
4. After dividing 144 by 6, you should get 24. This gives your answer for getting EXACTLY 636. However, in this case, you need more to reach your goal. Since you cannot sell fractions of a cup, just raising it by one can reach your goal. We can add one to 24, making it 25.
In conclusion, you need to sell 25 more cups to reach your goal.
A machine used to paint white lines on a road uses 250 litres of paint for
each 8km of road marked. Calculate:
a how many litres of paint would be needed for 200km of road
b what length of road could be marked with 4000 litres of paint.
a) Amount of paint needed for 200 km road = 6250 litres
b) Length of road that can be painted by using 4000 litres of paint = 128 km
Amount of paint used for painting white lines on road= 250 litres
Length which was painted = 8 km
By using unitary method;
Thus for 1 km amount of paint required = 250/8
= 31.25 litres
a) Amount of paint needed for 200 km road = 31.25 × 200
= 6250 litres.
therefore, Amount of paint needed for 200 km road = 6250 litres
b) Since for 1 km 31.25 liters paint is required this implies with 1 liter = 1/ 31.25 = 0.032 km can be covered.
Length of road that can be painted by using 4000 litres of paint = 4000× 0.032
= 128 km
Thus, Length of road that can be painted by using 4000 litres of paint = 128 km

The height, h (in meters above ground), of a projectile at any time, t (in seconds), after the launch is defined by the function h(t) = −5t2 + 13t + 6. The graph of this function is shown below. When rounded to the nearest tenth, what is the maximum height reached by the projectile, how long did it take to reach its maximum height, and when did the projectile hit the ground?
As we can se from the graph, the maximum value of the function is almost 15 meters, it is reached between t=1s and t=2s, and the height is 0 again when the time is approximately 3 seconds.
We can find the exact values by using the equation.
First, find the zeroes of the function by setting h(t)=0 and solving the quadratic equation for t:
[tex]\begin{gathered} h(t)=-5t^2+13t+6=0 \\ \Rightarrow t=\frac{-13\pm\sqrt[]{13^2-4(6)(-5)}}{2(-5)} \\ \Rightarrow t_1=-0.4;t_2=3 \end{gathered}[/tex]Then, the projectile hits the ground at t=3s.
To find the time at which the projectile reaches its maximum height, find the average between both zeroes:
[tex]t_{\max }=\frac{t_1+t_2}{2}=\frac{-0.4s+3s}{2}=1.3s[/tex]To find the maximum height, evaluate h at t=1.3s:
[tex]h(1.3s)=-5(1.3)^2+13(1.3)+6=14.45[/tex]Therefore, to the nearest tenth, the projectile reached a maximum height of 14.5 meters in 1.3 seconds and it took 3.0 seconds for it to hit the ground.
The correct option is the second one.
