franklin sold water bottles in two sizes, large ($2.50 each ) and regular ($1 each). He sold 113 bottles altogether and collecte
Ivahew [28]
Let's make a system of equations.

1 large bottle = l
1 regular bottle = r

l + r = 113
221 = 2.5l + r

Isolate r in the first equation and substitute it into the second equation:

l + r = 113
r = 113 - l

---

221 = 2.5l + 113 - l
221 = 1.5l + 113
108 = 1.5l
72 = l

Now, substitute that back into the first equation:

l + r = 113
72 + r = 113
r = 41

Finally, check your work by substituting back into both equations:

72 + 41 = 113    -->    113 = 113    <-- True
221 = 2.5(72) + 41    -->    221 = 180 + 41    <--True

Answer:
Franklin sold 72 large bottle of water and 41 regular-sized bottles of water.

A blueberry pie is shot out of a pie cannon from a height of 6m and with a velocity of 60 m/s. How many seconds will pass before
sveta [45]

Answer: 1.106 s

Step-by-step explanation:

This situation is related to projectile motion and one the equation that models the height of the blueberry pie in time is:

y=y_{o}+V_{o}sin(\theta) t-\frac{1}{2}gt^{2}

Where:

y=0 m is the blueberry pie final height (when it hits the ground)

y_{o}=6 m is the blueberry pie initial height

V_{o}=60 m/s is the blueberry pie initial velocity

\theta=0 \° is the angle, assuming the pie was shot horizontally

t is the time

g=9.8 m/s^{2} is the acceleration due gravity

Rewriting the equation:

0=y_{o}-\frac{1}{2}gt^{2}

Isolating t:

t=\sqrt{\frac{2y_{o}}{g}}

t=\sqrt{\frac{2(6 m)}{9.8 m/s^{2}}}

Finally:

t=1.106 s

HELPPPPP PLEASEEEEEE !!!!!!!A recipe requires x number of cups of flour to produce y number of servings.
Makovka662 [10]
Looking at 1 1/2 makes 12 cups, you can divide them to see the total of cups it would make with one cup of flower. 1 1/2 is equal to 1.5 , and with that information we do 12 divided by 1.5 which is 8. the answer is 8 per 1 cup of flower.
