a). Area = (length) (width)
= (60 ft) (√18 ft)
= (60 √18) ft²
= 60 √(9 · 2) ft²
= 60 (3) √2 ft²
= 180 √2 ft² (about 254.6 ft²)
b). Volume = (length) (width) (height)
= (60 ft) (√18 ft) (√10 ft)
= 60 √(180) ft³
= 60 √(4 · 9 · 5) ft³
= 60 (2) (3) √5 ft³
= 360 √5 ft³ (about 805 ft³)
The answer is 24. think of x as the original amount, and y as the new
amount. y times 1.5 is x, and y+12 is x. reverse that to figure out y,
which is what we need, and you have x/1.5 = y as well as x-12 = y. Use
the equal values method and make an equation x/1.5=x-12. solve this
equation to get x, which is 36. to figure out the new amount, y, you
need to subtract 12, which would help you get 24 as your final answer.
Answer:
3159.853 km
Step-by-step explanation:
The question says a square has an area of 9,984,670 km^2, which means that all sides are the same length. So you can use the equation:
9984670 = (x)(x) which rearranges to 998470 = x^2
get the square root and you get:
x = 3159.853 km
Answer:
y= -90x+250
Step-by-step explanation:
From the information given, the equation would be that the amount in the account would be equal to -90 that is the amount you withdraw from the account each week multiply for x that is the number of weeks plus $250 that is your initial balance:
y= -90x+250, where
y= amount in the account
x= number of weeks.
