Answer:
1/4 of the full container remains
Step-by-step explanation:
Step 1: Half the milk is poured out
i.e 1/2 of the milk remains
Step 2: 1/3 of what remains is poured out --> 2/3 of the remaining is not poured out.
Hence amount remaining after step 2 = 2/3 x 1/2 = 1/3 of the total
Step 3: 1/4 of what remains is poured out --> 3/4 of the remaining is not poured out.
Hence amount remaining after step 3 = 3/4 x 1/3 = 1/4 of the full container remains
50 km = 31.069 miles.
(1 km = 0.62 mile. simply multiply 50 km by 0.62 mile. )
So the first one is (7x)^(1/2) or square root of 7x minus - 5 square root all squared so
([7x^(1/2)]-[5^(1/2)]) times ([7x^(1/2)]-[5^(1/2)])
or 7x-(35x^(1/2))-5+(35x^(1/2)) or 7x-5
number 2
since 11 is 1/2 of 22 it can be written as
the square root of 3 or 3^(1/2)
Answer:Translation
Step-by-step explanation:
<em /><em>PURPLE MARBLES=P
WHITE MARBLES=W
</em>First, write out an equation showing the number of purple marbles.
P=5W-6
Then, write out the main equation.
W+P=96
W+5W-6=96
Add 6 to both sides.
W+5W=102
6W=102
Divide both sides by 6
W=17
Now that we know there are 17 white marbles, we can go back to the equation about how many purple marbles there are.
P=5W-6
Plug in the value for W, which is 17.
P=5(17)-6
P=85-6
P=79
To make sure your answer is correct, check your work by plugging in the values for P+W=96.
79+17=96
Answer: There are 79 purple marbles.
