Answer:

15 feets per second

Step-by-step explanation:

Given that:

Distance traveled by plane = 300 feets

Time taken by plane to travel such distance = 20 seconds

Rate at which the plane is diving is obtained thus :

Distance / time

= 300 feets / 20 seconds

= 15 feets / second

Hence, the plane is diving at a rate of 15 feets per second.

In a paint factory, an old conveyer line has filled 20 barrels of paint, and is filling more at a rate of 7 barrels per minute.

vagabundo [1.1K]

It takes 10 minutes for the two lines to have filled an equal number of barrels

Each line will have filled 90 barrels

Solution:

Let "x" be the number of minutes

The old conveyer line has filled 20 barrels of paint, and is filling more at a rate of 7 barrels per minute

Thus, a equation is framed as follows:

Old conveyor: 20 + 7(number of minutes)

Old conveyor: 20 + 7x ------- eqn 1

A worker just switched on a newer line that can fill 9 barrels per minute

Thus, a equation is framed as follows:

New conveyor: 9(number of minutes)

New conveyor: 9x -------- eqn 2

In a little while, the two lines will have filled an equal number of barrels.

Thus, eqn 1 must be equal to eqn 2

$20 + 7x =9x\\\\9x - 7x = 20\\\\2x = 20\\\\x = 10$

Thus it takes 10 minutes for the two lines to have filled an equal number of barrels

How many barrels will each line have filled?

Substitute x = 10 in any one of equations

Substitute in eqn 2

9x = 9(10) = 90

Thus each line will have filled 90 barrels

A gardener is distributing equal amounts of soil into pots. He has 12 kilograms of soil and he wants to put 1/3 of a kilogram in

CaHeK987 [17]

Answer:

36 pots

Step-by-step explanation:

If the gardener has 12kg and wants to put 1/3 in each pot, he would have to divide the 12 kilos by 1/3 kg

12 ÷ 1/3 =

12 x 3 = 36 pots

Help please!!! i need it by 2:00 today. i will give brainliest

MA_775_DIABLO [31]

Answer:

Below in bold.

Step-by-step explanation:

x-intercepts (-3,0) and (6, 0)

y-intercept (0, -5)

Axis of symmetry:

(-3 + 6) / 2 = 1.5

x = 1.5.

Domain = all real x.

Range is f(x) ≥ -6.

Graph is positive for x < -3 and x > 6.

Negative for -3 < x < 6.

Increasing for x > 1.5 and decreasing for x < 1.5.
