Answer:

3600 tickets were sold for the musical performance.

Step-by-step explanation:

Given that:

Number of people seated for musical performance = 108

Percent to people to arrive yet = 97%

It means that the people who have already come are 3%.

Let,

x be the number of tickets sold.

3% of x = 108

$\frac{3}{100}x=108\\$

0.03x = 108

Dividing both sides by 0.03

$\frac{0.03x}{0.03}=\frac{108}{0.03}\\x=3600$

Hence,

3600 tickets were sold for the musical performance.

For a circle with a radius of 6 feet, what is the measurement of the central angle (in degrees) that intercepts an arc with a le

makkiz [27]

Answer:

135 degrees

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=2\pi r$

we have

$r=6\ ft$

substitute

$C=2\pi (6)$

$C=12\pi\ ft$

step 2

Remember that the circumference of the circle subtends a central angle of 360 degrees

using proportion

Find out the measurement of the central angle (in degrees) that intercepts an arc with a length of 9π/2 ft

$\frac{12\pi}{360^o}=\frac{(9\pi/2)}{x}\\\\x=360(9\pi/2)/12\pi\\\\x=135^o$

X^2 + y^2 = 13,

Marysya12 [62]

Answer:

A, B, C and D. are solutions.

Step-by-step explanation:

x^2 + y^2 = 13

x^2 - y^2 = 5

Check which roots fit the original equations:

If x = 3, A gives

9 + y^2 = 13 giving y = +/- √4 = 2 or -2.

Now plug in x = 3 and y = 2 in the second equation:

9 - (2)^2 = 5

Therefore (3,2) is a solution of the 2 equations.

Following the same procedure for B, C and D:

B. Substituting x = 3 and x = -2 fits both equations so (3, -2) is a solution.

The same is true for C and D.
