4.7, because its tenths place is highest
Answer: About 81 feet
Step-by-step explanation:
15^2+80^2= diagional^2
225+6400=6625
square root of 6625
about 81
Answer:
This is not very clearly written, so i will answer in a general way.
When you have two numbers, A and B, such that:
B > A
and you want to find a number between A and B, you must find a number larger than A and smaller than B.
A < x < B.
Then if we have:
13 and 12.
The largest number is 13, then we want a number smaller than 13, and larger than 12.
An option is 12.5
12< 12.5 < 13.
6.42 and 2
The largest number is 6.42, then we want a number smaller than 6.42 and larger than 2.
An option is 4.
2 < 4 < 6.42
A harder example can be:
13.24 and 13.25
We want something larger than 13.24 and smaller than 13.25
Then we can write:
13.245
This is larger than 13.24 (by 0.005)
And smaller than 13.25 (by the same amount)
13.24 < 13.245 < 13.25
Answer: 2/561
Step-by-step explanation:
You have 36 possibilities for the first one
you have 35 possibilities for the second one
you have 34 possibilities for the third one
you have 33 possibilities for the last one
36*35*34*33
10*9*8*7= 5040
X = number of days, y = tunnel completion amount in ft
(6,410)(15,815)
slope = (815 - 410) / (15 - 6) = 405/9 = 45
y = mx + b
slope(m) = 45
(6,410)....x = 6 and y = 410
sub and find b
410 = 45(6) + b
410 = 270 + b
410 - 270 = b
140 = b
equation is : y = 45x + 140
after 26 days....x = 26
y = 45(26) + 140
y = 1170 + 140
y = 1310 ft <==
