In order to solve it we have to make two equations for Tony and Ray. But first we have to appeal to the formula : Distance = Speed*Time. Since we have two speeds we can match minimum speed and aximum speed with x and y respectively. So, now we can make an equation for both guys:
2x+3.5y=355 for Tony
2x+3y=320 For Ray
Then substracting : the Rae's equation from Tony's one in order to solve both equations.
You get 5y=35 solve for Y which is 70.
The next step is plug the value you have obtained into any equation to find a solution for x.
Let's take this one :
2x+3(70)=320
x=55

The answer is 520x.
Let x be the price of wallpaper per square feet.
Dimensions of a kitchen are:
width: w = 12 ft
length: l = 14 ft
height: h = 10 ft
If you need to put wallpaper in the room, you will put it only on the walls. There are 4 walls in the kitchen: two walls which dimensions are 12 ft and 10 ft, and two walls which dimensions are 14 ft and 10 ft. Since walls are of rectangular shape, we will use the following formula for the area of walls:
A = 2 * w * h + 2 * l * h
A = 2 * 12 * 10 + 2 * 14 * 10
A = 240 + 280
A = 520 ft²
So, if 1 square foot costs x, 520 square feet will cost 520x
Step-by-step explanation:
do 21×3.14= 65.94
then divide by 2 since its a semicircle
equals: 32.97
than find perimeter altogether
21+28+28+32.97= 109.97ft
Answer: 819x/50
Step-by-step explanation:
Answer:
240 square inches
Step-by-step explanation:
1 foot = 12 inches
to convert 4/3 ft to inches, multiply by 12
4/3 × 12 = 16 inches
the area of a square = base × height
base = 16, height = 15
16 × 15 = 240 square inches
