aksik [14]

Answer:

15 liters

Step-by-step explanation:

Given:

We need 5 liters of Yoda soda for 12 guest.

To find:

If we have 36 guest how many liters of Yoda soda we need.

Solution:

<u>By unitary method:</u>

For 12 guests, we need liters of Yoda soda = 5

For 1 guest, we need liters of Yoda soda = \frac{5}{12}

For 36 guests, we need liters of Yoda soda = \frac{5}{12}\times36=\frac{180}{12} =15\ liters

Therefore, we need 15 liters of Yoda soda for 36 guests.

If an object is projected upward from ground level with an initial velocity of 128 ft per sec, then it's height in feet after t
antoniya [11.8K]

Answer: t= 4 seconds

Maximum height = 256 feet

Step-by-step explanation:

The height of the object projected upwards after t seconds is given by

s(t)=-16t^2+128t.

The expression is a quadratic equation. When this equation is plotted on a graph, height against time, it takes the shape of a parabola whose vertex represents the maximum height attained by the object.

To get the value of t at the maximum height,

t = -b/2a

From the equation,

a = -16

b = 128

t = -128/-2×-16

= -128 /- 32= 4

it will take 4 seconds to reach its maximum height

To find maximum height attained, put t= 4 in the equation

s(t)=-16t^2+128t

S = -16× 4^2 + 128×4

S = -256+512

S = 256 feet

Going into a recent election, only about 62% of people old enough to vote were registered. In a community of about 55,200 eligib
luda_lava [24]
All we need to do is to divide the number of eligible voters by 62% to find out how many people have been registered:

55200 ÷ 62% =
= 55200 ÷ 62/100 =
= 55200 * 100/62 =
= 5520000 / 62 =
= 89032,25806451613 ≈          (note the rounding to the nearest whole number)
≈ 89032

Doublecheck:

89032 * 62% =
= 89032 * 62/100 =
= 5519984 / 100 =
= 55199,84 ≈                        (the difference is because of the rounding before)
≈ 55200

Answer: There were 89,032 people registered.
