Which of the following proportions could be used to find x?

OLga [1]

$\frac{x}{2}$ = $\frac{6}{1.5}$

The 2 right triangles are similar and so the ratios of corresponding sides are equal

The corresponding sides are x and 2, 6 and 1.5, hence

$\frac{x}{2}$ = $\frac{6}{1.5}$

A Super Happy Fun Ball is dropped from a height of 4 feet and rebounds 4 5 of the distance from which it fell. How many times wi

viva [34]

Answer:

More than 6.21 times

Step-by-step explanation:

The common ratio $r=\dfrac{4}{5}$

Distance of first bounce

$a_1=4\times \dfrac{4}{5}=\dfrac{16}{5}$

Second bounce

$a_2=ar^{n-1}=\dfrac{16}{5}(\dfrac{4}{5})^{2-1}\\\Rightarrow a_2=\dfrac{16}{5}(\dfrac{4}{5})$

n bounce

$a_n=ar^{n-1}\\\Rightarrow a_n=\dfrac{16}{5}(\dfrac{4}{5})^{n-1}$

Now the nth bounce will be less than 1 feet

$\dfrac{16}{5}(\dfrac{4}{5})^{n-1}$

Applying logarithms on both sides we get

$(n-1)\ln \dfrac{4}{5}\dfrac{\ln\dfrac{5}{16}}{\ln \dfrac{4}{5}}+1$

The inequality changes as both $\ln\dfrac{5}{16}$ and $\ln \dfrac{4}{5}$ are negative numbers.

So,

$n>6.21$

Hence, the number of bounces is more than 6.21 times.

3x-z+2x+3y+2x<———— Can you please help me with solving this expression please?

SVETLANKA909090 [29]

Answer:

7x+3y-z

Step-by-step explanation:

Starting off by separating the different variables, you should get:

(3x + 2x ) + (-z + 2z) + (3y)

Then you simplify in between the parentheses...

(5x) + (z) + (3y)

And you finally simplify the equation with only a single number of a certain variable to get your answer...

5x + z + 3y
