Answer:
true
Step-by-step explanation:
The student clearly made a mistake, because he found that he needs to mix more solution that he wants to end up with. Mixing 1.17 L of one solution with more of some other solution will make more than 1 L of another solution.
The mistake is writing <em>x</em> - 1 instead of 1 - <em>x</em>.
Answer: Option B is the correct answer.
Step-by-step explanation:
Let x represent the number of pennies.
Out of 40 coins, 16 are dimes. This means that the number of coins remaining is
40 - 16 = 24
Half of the remaining coins are quarters. This means that the number of quarters is
1/2 × 24 = 12 quarters
the rest are pennies and nickels. This means that the total number of
pennies and nickels is 12
There are 2 nickels for every penny. This means that the number if nickels is 2x. Therefore,
2x + x = 12
3x = 12
x = 12/3 = 4
there are 4 pennies
Answer:
Option (2)
Step-by-step explanation:
Standard form of the polynomial will be in the form of (ax⁴+ bx³+ cx²+ dx + e).
Which means exponents of each successive term will be in the reducing form and the last term will be a constant term.
Now we can rearrange the terms of the given polynomial (5x + 2x⁴ - 4) for the standard form.
(2x⁴ + 5x - 4)
Since, degree of the leading term = 4
And number of terms = 3
Given polynomial is a fourth degree trinomial.
Option (2) will be the answer.
If they drank 40%, then there are (100 - 40) = 60% still in the glass.
60% of 32 ounces = 0.6 x 32 = 19.2 ounces .
