Answer:

78 = (5x - 2) \\  \\ 78 = 5x - 2 \\  \\ 78 + 2  = 5x \\  \\ 80 = 5x \\  \\ x =  \frac{80}{5}  \\  \\ x = 16

it's was vertical angel they are equal ( = ) each other

it's was helpful to you

<h2><u>Solution</u><u>:</u><u>-</u></h2>

<u>\\  \mapsto78 = (5x - 2)</u>

<u>\\  \mapsto78 = 5x - 2</u>

<u>\\  \mapsto78 + 2 = 5x</u>

<u>\\  \mapsto80 = 5x</u>

<u>\\  \mapsto \frac{80}{5}  = x</u>

<u>\\  \mapsto16 = x</u>

<u>\\ \mapsto \: x = 16</u>

<h2><u>Answer</u><u>:</u><u>-</u></h2>

[Hence, the value of x is 16.]

Answer: The area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.

Step-by-step explanation:

Let r be the radius of the circle having the center O,

⇒ The area of the circle = \pi r^2  square unit.

And, the central angle AOB = \frac{5\pi}{4}\text{ radian}

=(\frac{5\pi}{4}\times \frac{180}{\pi})^{\circ}  ( since, \pi = 180° )

=(\frac{900}{4})^{\circ}

=225^{\circ}

Hence, the area of sector AOB

=\frac{225^{\circ}}{360^{\circ}}\times \pi r^2

=\frac{5}{8}\times \pi r^2 square unit.

Now,

\frac{\text{Area of sector AOB}}{\text{Area of circle}}=\frac{\frac{5}{8}\times \pi r^2}{\pi r^2}

=\frac{5}{8}

⇒ Area of sector AOB = 5/8 × Area of the circle.

Hence, the area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.

mixas84 [53]

Answer:

85751

Step-by-step explanation:

81924

+ 3827

_______

 85751


- Start from the right side, 4 + 7 = 11, but the 1 is carried over

- 2 + 2 + 1 = 5

- 9 + 8 = 17, but the 1 is carried over

- 1 + 3 + 1 = 5

- 8 + 0 = 8

Thus, the answer becomes 85751.

A particular computer takes 11 minutes to download a 33​-minute TV show. How long will it take the computer to download a 2.5​-h
zhenek [66]

First off.. we need to get the units the same.  All in hours,

or all in minutes.  36 minutes = 36/60 hours = 3/5 hours = 0.6 hours.

12 minutes = 12/60 hours = 1/5 hours = 0.2 hours

Set up a proportion:

0.2 is to 0.6 as x is to 22.5

x/22.5 = 0.2/0.6

x = 0.2(22.5)/0.6

x = 7.5 hours


thanx
