Answer:
Step-by-step explanation:
Some foundation pieces:
Floor is 30 ft^2
tiles are 3w
Equation:
30=(3w)*10
3=3w
1=w
Now that you know that w has to 1 you can write the formula 30=(3w)×10
Answer:
x² - 9x +14 = 0
x²-x(7+2)+14=0
x²-7x-2x+14=0
x (x-7) -2(x-7)
(x-7) (x-2)
either x-7=0
x=7
or (x-2)=0
or x=2
Step-by-step explanation:
Find the circumference to see how much of the wheel is touhing the ground
c=2pir
c=2pi1.9
c=2.8pi
2.8pi=distance per 1 rotation
number of rotations per second times 2.8pi=12feet per second
dvide both sides by 2.8pi
number of rorations per second=12/2.8pi
number of roations per second=6/1.4pi
number of roations per second=3/0.7pi
number of roations per second=30/7pi
aprox
number of roations per second=1.364 rotations per second
Answer:
219 Seconds ; He was 1 second faster
Step-by-step explanation:
Two halfs equal one whole, meaning both of the times added will equal the full time he took:
