Answer:
In the end he would have made a total of 234 dollars
Step-by-step explanation:
440-128=312 This is the amount left after taking out the rotten apples
312/4= 78 Since he then put the apples in groups of four, he would have 78 groups of four apples a piece.
78 X 3= 234 Lastly he would have a profit of 234 dollars seeing as he has 78 groups of apples, each individual group costing 3 dollars a piece
From my research the given equations are:
30x + 30y = 450

The problem asks to solve for the number of square feet Paul has shoveled more than Melinda. This can be solved by using the system of equations to solve for the values of x and y (the respective values of how each they have shoveled each).
Using the system of equations, the following values were obtained:
x = 6
y = 9
Therefore, Paul has shoveled 3 square feet per minute more than Melinda.
Answer:
6.25 feet.
Step-by-step explanation:
Please find the attachment.
Let L be the length of the ramp in feet.
We have been given that steel loading ramps are used to load a lawn mower onto a truck bed 37.5 inches above the ground. The ramp make a 30° angle with the ground.
We can see from our attachment that ramp and truck bed forms a right triangle with ground. The truck bed is opposite side and length of ramp is hypotenuse of our given angle.
Since we know that Sine relates the opposite and hypotenuse of a right triangle, so we will use Sine to solve for L.
Upon substituting our given values in above formula we will get,
Therefore, the length of the ramp is 75 inches.
Let us convert the length of ramp in feet.
1 feet = 12 inches.
Therefore, the length of the ramp is 6.25 feet.
Answer:
6 and 15
Step-by-step explanation:
n1 + n2 = 21
2(n1) + 3 = n2
n1 = 6
n2 = 15
6 + 15 = 21
