Answer:

175 guests

Step-by-step explanation:

19 + 121 = 4/5x

140= 4/5x (multiply by the reciprocal of 4/5 to get x by itself: 5/4)

140 x 5/4 = x

x= 175

A ball is dropped from a height of 10 meters. Each time it bounces, it reaches 50% of its previous height. The total vertical di
yan [13]

Answer:

28.75 m.

Step-by-step explanation:

It is given that a  ball is dropped from a height of 10 meters. Each time it bounces, it reaches 50% of its previous height. So,

For first bounce the vertical distance a_1= 10\ m

For next bounce ball has to travel up and down by 50% of previous distance, i.e., 10 m.

For second bounce the vertical distance a_2=2\times (\dfrac{50}{100}\times 10)=2(5)=10\ m

Similarly,

For third bounce the vertical distance a_3=2\times (\dfrac{50}{100}\times 5)=2(2.5)=5\ m

For fourth bounce the vertical distance a_4=2\times (\dfrac{50}{100}\times 2.5)=2(1.25)=2.5\ m

For fifth bounce the vertical distance a_5=2\times (\dfrac{50}{100}\times 1.25)=2(0.625)=1.25\ m

The total vertical distance down the ball has traveled when it hits the the 5th time is

\text{Total distance}=a_1+a_2+a_3+a_4+a_5

\text{Total distance}=10+10+5+2.5+1.25  

\text{Total distance}=28.75\ m

Therefore, the total vertical distance  down the ball has traveled when it hits the the 5th time is 28.75 m.

Verizon [17]
X^2+4x=-3
x^2+4x+3=0
(x+1)(x+3)=0
x+1=0 so x=-1
x+3=0 so x=-3
so the solution is x=-3,-1
Hope this helped! Please rate my answer if I helped you! Any questions please feel free to ask! Thank you so much!

Divide (16x6 − 12x4 + 4x2) by 4x2.
Degger [83]
We know that
<span>(16x6 − 12x4 + 4x2) / 4x2
is equal to
[16x6/4x2]+[-12x4/4x2]+[4x2/4x2]
=[4x4]+[-3x2]+[1]
=4x4-3x2+1

the answer is
</span>4x4-3x2+1<span>

</span>
