Answer:
The dog should receive 400 mL of the i.v. bag.
Step-by-step explanation:
40% x 1000 = 400
(4*4*10)*3
160*3=480
(5*3*10)*2
150*2=300
480+300=780 cub. meters
Answer:
D. 63%
Step-by-step explanation:
the white marble was picked out 41 of the 65 times, so 41/65
divide 41 by 65 in your calculator and you get .6307
then multiply it by 100 because it asked for a percentage and you get 63%
Ta-Da!
Let the first integer be x. Then the next consecutive integer is x+1.
Translating the word problem into symbols, x(x+1)-20(x+1) = 442.
Then x^2 + x - 20x - 20 = 442
or x^2 - 19x - 462 = 0
Solve by completing the square:
x^2 - 19x + 90.25 - 90.25 - 462 = 0
(x-9.5)^2 - 552.25 = 0
Taking the positive square root of both sides, we get x-9.5 = 23.5, or
x = 33
The two consecutive integers are 33 and 34.
Check: (33)(34)-20(34) = 442 (as expected).
