andriy [413]

I'm pretty sure the original price would be $90.75 because 3/4 is .75, so all you have to do is add that to the $90

A water and sprinkle our sins water out in a circular pattern how many feet away can it spread water if the area formed by the w

ludmilkaskok [199]

Answer:

11 feet away.

Step-by-step explanation:

Given:

A water and sprinkle our sins water out in a circular pattern

Area formed by the watering pattern is 379.94 square feet

To find:

How many feet away can it spread water means we have to find distance from the middle point to the last end of circular pattern of water sprinkling (radius of a circle) = ?

solution:

By using ,Area of a circle = $\pi r^{2}$

Area of a circle = 379.94 square feet (given)

$\pi r^{2}$ = $379.94$

$3.14\times r^{2} = 379.94\\$

Dividing both side by 3.14

$r^{2} = \frac{379.94}{3.14} = 121$

Taking square root both side

$r = \sqrt[2]{11\times11}$ (Taking common)

$r = 11$

Therefore, radius = 11

Thus, it can spread water 11 feet away.

Need help so confused thankssss

Let complementary angle be x,

Then the other angle is 4x

x + 4x = 90 ( complementary angles)

5x = 90

x = 90/5

x = 18,

The measure of the smaller angle = 18

And the measure of the larger angle = 4x

= 4 * 18

= 72

The supplementary of the larger angle is,

Let y be the other supplementary angle.

72 + y = 180 ( Supplementary angles)

y = 180 - 72

y = 108.

Hence, the other supplementary angle is 108 degrees.

Hope you understood. Plzzz let me know if you have any doubts.

If 12 children represents 12.5% of the people attending a concert, how many people are attending the concert

NeTakaya

96 people are attending the concert.

Step-by-step explanation:

Given,

Number of children at concert = 12

This represents 12.5% of the people attending concert.

Let,

p be the total people attending concert.

12.5% of p = 12

$\frac{12.5}{100}*p=12\\0.125p=12$

Dividing both sides by 0.125

$\frac{0.125p}{0.125}=\frac{12}{0.125}\\p=96$

96 people are attending the concert.
