The admission fee at a small fair is $1.50 for children and $4.00 for

1 answer:

7 0

1.50c + 4.00a = 5,050

c + a = 2,200

-1.50 (c + a = 2,200)

1.50c + 4.00a = 5,050
-1.50c - 1.50a = -3,300

2.5a = 1750

a = 700

c + 700 = 2,200

c = 1500

700 adults and 1500 children attended the fair.

A central angle of a circle measures 1.5 radians. If the radius of the circle is 3 cm, what is the area of the related sector?

soldi70 [24.7K]

Answer:

Option B. $6.75\ cm^{2}$

Step-by-step explanation:

we know that

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=3\ cm$

substitute

$A=\pi (3^{2})=9 \pi\ cm^{2}$

Remember that

$2\pi$ radians subtends the complete circle of area $9 \pi\ cm^{2}$

by proportion

Find the area of the related sector for a central angle of $1.5$ radians

Let

x------> the area of the related sector

$\frac{9 \pi}{2\pi}\frac{cm^{2}}{radians} =\frac{x}{1.5}\frac{cm^{2}}{radians}\\ \\x=9*1.5/2\\ \\x= 6.75\ cm^{2}$

The sides of a triangle measure 3√6 2√24 7√54 what is the perimeter of the triangle

Sliva [168]

Answer:

Step-by-step explanation:

3*√6 + 2√24 + 7√54= P

3√6 + 2√2*2*6 + 7√3*3*6

3√6 + 2*2√6+7*3√6

3√6 + 4√6 + 21√6

28√6 = the perimeter.
