Answer:
D. 405
Step-by-step explanation:
First, you find the area of the swimming pool without the water. That is 9 x 9 = 81. Then you multiply the area (without water) by 5 to find the area with the water.
Answer:
A, E, F, D
Step-by-step explanation:
Done this before
A = oz of the solution A
b = oz of the solution B
The scientist knows that solution A is 45% salt and solution B is 95% salt. She wants to obtain 80 ounces of a mixture that is 65% salt.
a + b = 80
0.45a + 0.95b = 0.65*80
by solving the above system of equations you'll find····
a = 48 oz
b = 32 oz
~I hope this helped~
If it doesn't make since, I can try to switch up the wording ^^
14/84 x100 =. 1/6 x 100 = 16.66%
the answer is
x=8y/3(1-8y)
y=3x/8(1+3x)
hope this helped l used cymath to solve this problem.
good day : )
