If he started at 5:35 add 50 minutes to that it would be 6:25
The equation of this line is x = 7 and it's slope is undefined aswell.
Answer:
$81.92
Step-by-step explanation:
tip applies to the cost of the meal before the discount
$78.02 x 0.2 = $15.6
meal cost after the discount
$78.02(1 - 0.15) =
= $78.02 x 0.85
≈ $66.32
the total cost of the meal
$15.6 + $66.32 = $81.92
tiles are needed .
<u>Step-by-step explanation:</u>
Here we have , Raj builds a side table in the shape of a cube. Each edge of the cube measures 15 inches. Raj wants to cover the top and four sides of the table with ceramic tiles. Each tile has an edge length of 5 inches. We need to find How many tiles will he need . Let's find out:
Total area to be covered by tile for covering the top and four sides of the table is
⇒ ![a^2+a^2+a^2+a^2+a^2](https://tex.z-dn.net/?f=a%5E2%2Ba%5E2%2Ba%5E2%2Ba%5E2%2Ba%5E2)
⇒
, Where a is edge of the cube measures 15 inches So , Area :
⇒ ![5(15)^2](https://tex.z-dn.net/?f=5%2815%29%5E2)
⇒ ![5(225)](https://tex.z-dn.net/?f=5%28225%29)
⇒ ![1125 in^2](https://tex.z-dn.net/?f=1125%20in%5E2)
Now , Area of each tile is :
⇒
, Where side is edge length of 5 inches
⇒ ![(5)^2](https://tex.z-dn.net/?f=%285%29%5E2)
⇒ ![25in^2](https://tex.z-dn.net/?f=25in%5E2)
So , Number of tile needed is
⇒ ![\frac{1125}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B1125%7D%7B25%7D)
⇒ ![45](https://tex.z-dn.net/?f=45)
Therefore ,
tiles are needed .
