The interior angles of a quadrilateral are 2x+15 2x-5 3x+75 3x-25 find x and the smallest interior angle largest interior angle
BartSMP [9]

Answer:x=30^{\circ}

Step-by-step explanation:

We know sum of the interior angles of a quadrilateral is 360^{\circ}

therefore  we can write

(2x+15)+(2x-5)+(3x+75)+(3x-25)=360^{\circ}

so

\Rightarrow 10x+60=360

\Rightarrow 10x=300

\Rightarrow x=30^{\circ}

So smallest interior angle is (2x-5)^{\circ}=(60-5)=55^{\circ}

Largest interior angle =3x+75=90+75=165^{\circ}

How many radians does the minute hand of a clock rotate through over 10 minutes? How many degrees?
Leto [7]

Answer:

10 minutes =  1.047198 radians

10 minutes = 60 degree

Step-by-step explanation:

we know that

There is 60 minutes in an hour

so it is This is 2 Pi radians

so 10 minutes is  \frac{10}{60} or  \frac{1}{6} th of an hour

and here we know  the hand will travel  of the full circle

and we know A full circle measures 2 Pi radians

2 × pi radians = 360 degrees

10 minutes = \frac{1}{6} ×   2 × pi radians

10 minutes =  \frac{1}{3} × pi radians

10 minutes =  1.047198 radians

10 minutes = 60 degree

A long spring is attached to a wall at one end. A pulse is sent down the spring. When the pulse reaches the wall it bounces back
Vika [28.1K]

It is given that at the moment the first pulse reaches the wall, a second pulse is sent down the spring. Now, when the two pulses meet they will be subject to the principle of superposition and as one is upside down (the reflected pulse) and the other is up (the second pulse), there will be a nullifying effect and the spring will appear straight for that split moment. Thus we can say that there will be a destructive interference where one pulse will destroy the other or in other words nullify the other's existence. After that moment the pulses will move towards their respective ends as if nothing happened.

Hence, Option B is the correct option.

The sum of three consecutive even integers is 108. What is the largest number?
nasty-shy [4]
Smallest #: x
Medium #: x + 2
Largest #: x + 4

Equation:
(x) + (x+2) + (x+4)= 108
3x + 6 = 108
3x = 102
x = 34

Largest #: x + 4
Largest #: 34 + 4
Largest #: 38
