Multiply 5 by 5 to get 25
25ab
Answer:
0
Step-by-step explanation:
To find the slope of two points, here is the formula (y2-y1)/(x2-x1)
So we have (1,2) and (4,2),
We let y2 = 2 and y1 = 2 and we let x2 = 4 and x1 = 1
So, (2-2)/(4-1) = 0/3
Our slope is 0.
Answer:
a) 
b) t = 0.3 seconds
c) d = 4.9t²
d) d = 11 cm.
Step-by-step explanation:
One test involves catching a 1 m ruler and measuring the distance, d in meters, that the ruler will travel before being caught, the reaction time t in seconds is then calculated using the formula
.......... (1)
a) the simplified expression is
......... (2)
b) If d = 44 cm = 0.44 meters, from equation (2) we get,
t = 0.299 seconds ≈ 0.3 seconds (Approximate)
c) If we make d as the subject of the equation, then
⇒ d = 4.9t² .......... (3)
d) Now, if 
seconds, then from equation (3) we get,
d = 4.9 (0.15)² = 0.11 meters = 11 cm (Answer)
Answer:
Her estimate is reasonable.She can make 25 completed centerpieces
Step-by-step explanation:
Estimate 20 flowers per centerpiece. 430 flowers divided by 20 flowers per centerpiece.
430 /20 is approximately 21 centerpieces. Her estimate is reasonable.
430/20 Divide the top and bottom by 10
43/2 is 21*2 = 42 with 1 left over 21 1/2
We know we underestimated when we rounded 17 to 20. Se we are a little under with 21.5
Exact answer:
430÷17
17 goes into 43 2 times (17*2 = 34 43-34 = 9 left over)
17 goes into 90 5 time (17*5 = 85 90-85 = 5 left over)
She can make 25 completed center pieces
there are 3600 seconds per hour
5280 feet per mile
1 foot per second = 3600/5280 = 0.681818 Miles per Hour
60 seconds per minute
so 1500/60 = 25 feet per second
25 x 0.681818 = 17.05 miles per hour
