How many 1/4 cup servings of raisins are in 7/8 cups of raisins?

Ostrovityanka [42]

Answer:

Step-by-step explanation:

Divide 7/8 by 1/4. (You divide the "supply" of raisins into 1/4 cup "parts".)

$\frac{7}{8} \div \frac{1}{4} = \frac{7}{8} \times \frac{4}{1} = \frac{28}{8} =\frac{7}{1} =7$

Multiply 7/8 by the reciprocal of 1/4 ("flip" the 1/4).

The result is 28/8, which can be simplified ("reduced") to 7.

Answer:

2.0 seconds

Step-by-step explanation:

Given quadratic functions:

$\begin{cases}y=-7x^2+26x+3\\y=-6x^2 +23x+5\end{cases}$

To find the time, in seconds, that the balloons collided at the highest point, substitute one equation into the other equation and rearrange to equal zero:

$\begin{aligned}-6x^2+23x+5 & = -7x^2+26x+3\\-6x^2+23x+5+7x^2 & = -7x^2+26x+3+7x^2\\x^2+23x+5 & = 26x+3\\x^2+23x+5-26x & = 26x+3-26x\\x^2-3x+5& = 3\\x^2-3x+5-3& = 3-3\\x^2-3x+2& = 0\end{aligned}$
