Hiro painted his room. After 3333 hours of painting at a rate of 8888 square meters per hour, he had 28282828 square meters left
lorasvet [3.4K]

Answer:

y = 52 - 8x

Step-by-step explanation:

If he painted for 3 hours at a rate of 8 square meters per hour, the area painted was:

A_P=8*3=24\ m^2

If after 24 squared meters painted, there are still 28 left, the total area is:

A=24+28 = 52\ m^2

The area still left to paint is initially 52 squared meters and decreases at a rate of 8 square meters per hour, the function that describes the relationship between the area left to paint (y) and number of hours (x) is:

y = 52 - 8x

Game 1, 2, 3 Yard 157, 309, 172.
Bas_tet [7]
<span>Part A. How many total yards did Ed run in the first 3 football games.
</span>total yards Ed = 157 + 309 + 172 = 638

<span>Part B. How many more total running yards did Rico have than Ed after the first 3 games of the season?
</span>total yards Rico = 3*total yards Ed = 3*638 = 1914
so Rico has more yards than Ed, 1914 - 638 = 1276, that is, Rico has 1276 more yards than Ed after the 3 first games

Find polar coordinates of the point that has rectangular coordinates (-1, -2).
ch4aika [34]

Answer:

Step-by-step explanation:

The length of the polar coordinates ray is found using the Pythagorean Theorem:  ray length = √( (-1)^2 + (-2)^2 ) = √( 1 + 4) = √5

Because both the x- and the y-coordinates here are negative, the ray is in Quadrant III.  Measuring the angle counterclockwise from 0°, we get

Ф = 180° + arctan 2/1, or Ф = 180° + 63.43°, or 243.43°

The desired polar coordinates are (2√2, 243.43°)

The rectangular pool is 45 feet x 18 feet. The fence needs to be 5 ft away from the edges of the pool or a 5 ft border. How many
Mama L [17]

Answer:

The length of fencing is 146 feet.

Step-by-step explanation:

The length of fencing is equal to the perimeter of the rectangle plus 8 times the width of the border between the edge of the pool and the fence. By Geometry, we find that the perimeter (p), measured in feet, is equal to:

p = 2\cdot (w+f)+2\cdot (l+f) (1)

Where:

w - Width of the pool, measured in feet.

l - Length of the pool, measured in feet.

f - Width of the border, measured in feet.

If we know that w = 45\,ft, l = 18\,ft and f = 5\,ft, then the length needed of fencing is:

p = 2\cdot (45\,ft+5\,ft)+2\cdot (18\,ft+5\,ft)

p = 146\,ft

The length of fencing is 146 feet.
