Answer:

2135 miles

Step-by-step explanation:

ok so the plane is going at a speed of 610 mph

1 hour = 610 miles

this is a whole break down of what goes on in my head

610 x 3.5 = ?

600 x 3 = 1800

600 x .5 = 300

10 x 3 = 30

10 x .5 = 5

1800 + 300 + 30 + 5 = 2135

the plane will fly 2135 miles in 3.5 hours

Answer:

2135

Step-by-step explanation:

610 divided by to is 305 so the half of the hours the plane flys 305 miles.

The Wellbuilt Company produces two types of wood chippers, economy and deluxe. The deluxe model requires 3 hours to assemble and
seropon [69]

Answer:

The maximum profit is reached with 4 deluxe units and 6 economy units.

Step-by-step explanation:

This is a linear programming problem.

We have to optimize a function (maximize profits). This function is given by:

P=98D+72E

being D: number of deluxe units, and E: number of economy units.

The restrictions are:

- Assembly hours: 3D+2E\leq24

- Paint hours: 0.5D+1E\leq8

Also, both quantities have to be positive:

D\geq 0\\\\E\geq0

We can solve graphically, but we can evaluate the points (D,E) where 2 or more restrictions are saturated (we know that one of this points we will have the maximum profit)

(8;0) \rightarrow  P=98*8+72*0= 784\\\\(0;8) \rightarrow P= 98*0+72*8=576\\\\(4;6) \rightarrow P=98*4+72*6=824

The maximum profit is reached with 4 deluxe units and 6 economy units.

Find the slope of the line represented by the data on the picture
arsen [322]

Answer:

slope = - 4

Step-by-step explanation:

Calculate the slope m using the slope formula and any 2 ordered pairs from the table.

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 8) and (x₂, y₂ ) = (- 1, 4) ← 2 points from the table

m = \frac{4-8}{-1+2} = \frac{-4}{1} = - 4
