Step-by-step explanation:

At time zero the level was 7 gallons and at time 3 min, the level was 5 gallons.

<u>Take two points:</u>

  • (0, 7) and (3, 5)

<u>Find the rate of change:</u>

  • m = (5 - 7)/3 = 2/3

This is a 2 gallons per 3 minutes

<u>Tank holds 10 gallons, it was emptied by 3 gallons and it took:</u>

If line segment ab is defined by the endpoints a(4,2) and b(8,6) , write an equation of a line that is the perpendicualr bisecto
BlackZzzverrR [31]
Slope of line ab  = 6-2 / 8-4  = 4/4 = 1
So the slope of the perpendicular line is -1/1  = -1
This line passes through the midpoint of ab
The midpoint of ab  =  ( 8+4 / 2 , 2+6 / 2) =  (6, 4)
Finding the equation of the perpendicular line:-
y - y1 = -1(x - x1)  where x1 = 6 and y1 = 4:-
y - 6 = -1(x - 4)
y = -x + 10 is the answer

A parking space shaped like a parallelogram has a base of 17 feet and a height of 9 feet if a mini car 6 feet long and five feet
lesantik [10]

Answer:

123 cm²

Step-by-step explanation:

First of all, we need to know how exactly to find the area of a parallelogram.

<u>Area</u><u> </u><u>of</u><u> </u><u>parallelogram</u><u>=</u><u> </u><u>Base</u><u>*</u><u>Height</u>

PARALLELOGRAM-

BASE= 17 ft

HEIGHT= 9ft

AREA= 17*9= 153 cm²

The area of parallelogram, will be considered as WHOLE AREA.

Now,

AREA OF MINI CAR-

length= 6 ft

Width= 5 ft

Area= 6*5= 30 ft ²

Square feet uncovere-

153 ft²- 30 ft²= 123 ft²

HOPE IT HELPS!
