<h3>Answer: </h3>

about 1.768 seconds

<h3>Explanation:</h3>

Since the phone is <em>dropped</em>, the first equation applies. The final height is assumed to be zero, so we have ...

... h(t) = 0 = -16t² +50

... 16t² = 50 . . . . . . . . add 16t²

... t² = 50/16 . . . . . . . . divide by 16

... t = √3.125 . . . . . . . take the square root

... t ≈ 1.768 . . . . . . . . round to milliseconds

HELPPPP PLEASEEE IM BEGGING SOMEONE PLEASE PLEASE HELP

Given:

The figure of a rhombus QRST.

To find:

A. The value of x.

B. The measure of angle RQP.

Solution:

A. We need to find the value of x.

We know that the diagonals of a rhombus are perpendicular bisectors. It means the angles on the intersection of diagonals are right angles.

m\angle RPS=90^\circ                       [Right angle]

(5x+15)^\circ=90^\circ

(5x+15)=90

5x=90-15

5x=75

Divide both sides by 5.

x=\dfrac{75}{5}

x=15

Therefore, the value of x is 15.

B. We need to find the measure of angle RQP.

From the given figure, it is clear that

m\angle RQP=(2x+3)^\circ

Putting x=15, we get

m\angle RQP=(2(15)+3)^\circ

m\angle RQP=(30+3)^\circ

m\angle RQP=33^\circ

Therefore, the measure of angle RQP is 33 degrees.

Is 5 + 3x1 - x) equivalent to 8 – 8x?
nalin [4]

Answer:

no

Step-by-step explanation:

5+3x is equal to 8x.

if there is no number in front of a variable, it is understood to be a one. so 1-x would basically be 1-1. this cancels out the x, making it impossible for the equivalent equation to be 8 - 8x

4x + 2(x + 8) = -19+ x
Likurg_2 [28]

4x + 2(x + 8) = -19 + x

4x + 2x + 16 = -19 + x

6x + 16 = -19 + x

6x + 35 = x

-5x = 35

x = -7
