A standard interior staircase has steps each with a rise (height) of 21 cm and a run (horizontal depth) of 24 cm. Research sugge
Alisiya [41]

Answer:

The staircase would extends 1.20 m if the changes were made.

Step-by-step explanation:

Acording tho the statement the total heigth is 5.04 m, that is 504 cm, each steps rises 21 cm. with this information we can calculte how many steps are in the whole staircase:

Number steps= \frac{Total heigth}{each step} \\Number steps= \frac{504}{21}  = 24 steps

To calculate how much the staircase will extend, whe have to multiply the horizontal depth times the number of steps.

using the run of 24 cm that gives us a lengt of 576 cm and if the changes were made the new length will be 696 cm.

So the staircase would extend an amount of (696 - 576), that is 120 cm, or 1.20 m, if the changes were made.

Will give brainliest worth 25 points
dezoksy [38]

Find the difference in temperature between each 1000 feet:

From 1 to 2: 30 - 23.5 = 6.5

From 2 to 3: 23.5 - 17 = 6.5

From 3 to 4: 17 - 10.5 = 6.5

The temperature change is constant as it drops 6.5 degrees for every 1000 foot gain in elevation.

At 5,000 feet the temperature would be : 10.5 - 6.5 = 4

At 6,000 feet: 4 - 6.5 = -2.5

At 7,000 feet: -2.5 - 6.5 = -9

At 8,000 feet: -9 - 6.5 = -15.5

At 8,000 feet the temperature would be  -15.5 degrees.

Consider the expression: (x + 3)•(y + 1)•(x + 2)
emmainna [20.7K]

Answer:

Step-by-step explanation:

First we multiply x through (y+1). This equals xy +x.

Second we take 3 through (y+1). This equals 3y+3.

Next we take xy + x through (x+2). This equals 2x squared, y + 2x squared.

Fourth we take 3y+3 through (x+2). This equals 6xy + 6x.
