The reasonable estimates are indicated in the following choices:
A) 1 foot
B) 2 feet
C) 5 feet
D) 9 feet
So, from the given choices, 2 feet or approximately 24
inches would be the most viable answer because most standard desks have a
height around 28 inches to 30 inches. 1 foot is too low, while 5 feet and 9
feet are too high. Therefore, 3 to 4 feet would be the most perfect answer but
since we have a limited number of options, the nearest reasonable estimate
value would be 2 feet. <span>The original numbers from a problem does not exceed in a reasonable
estimate.</span>
4x-2 bc a pos x neg = neg
we are given
exterior angle is 18
so,
now, we can use formula
number of sides of regular polygon = 360/(exterior angle)
so, we get
so, number sides is 20..........Answer
The gallons of the first brand of antifreeze should be 60 gallons.
The gallons of the second brand of antifreeze should be 90 gallons.
<h3>What are the linear equations that represent the question?</h3>
0.2f + 0.45s = 52.50 (0.35 x 150) equation 1
f + s = 150 equation 2
Where:
- f = gallons of the first antifreeze
- s = gallons of the second antifreeze
how many gallons of each brand of antifreeze must be used?
Multiply equation 2 by 0.2
0.2f + 0.2s = 30 equation 3
Subtract equation 3 from equation 2
0.25s = 22.50
s = 22.50 / 0.25
s = 90
f = 150 - 90 = 60 gallons

1/7(1000) = 1/7(7000/7)
1*7000
7*7
7000
49
1000
7
so 1/7(1000) = 1000/7 or 142 6/7
