Matilda is planning a walk around the perimeter of wedge park, which is shaped like a circular wedge, as shown below. the walk a

alukav5142 [94]

The area of the circular sector is
$A=\frac{1}{2}r^{2}\theta$

From that, the equation for the central angle is
$\theta=\dfrac{2A}{r^{2}}$

The perimeter of the circular sector is the sum of the arc length and twice the radius.
$P=2r+r\theta\\\\P=r(2+\theta)$

From that, the equation for the central angle is
$\dfrac{P}{r}=2+\theta\\\\ \theta=\dfrac{P}{r}-2$

The value of r can be found by equating these two expressions for θ.
$\dfrac{2A}{r^{2}}=\dfrac{P}{r}-2\\\\2r^{2}-Pr+2A=0\\\\2r^{2}-2.9r+0.5=0$

By any of several means, you can find that r=0.2 or 1.25. The latter value corresponds to the requirement that the central angle be less than 90°. The radius is ...
1.25 miles.

Complete each of the ratios on the table show calculations

arsen [322]

Answer:

From left to right:

2, 4, 32

Step-by-step explanation:

Using the one column which is completed, determine the ratio of yellow to blue by reducing to lowest terms.

yellow to blue = 8 to 16

8 and 16 are both divisible by 8. 8/8 = 1 and 16/8 = 2

8 to 16 = 1 to 2

This means there is half as much yellow paint as there is blue paint. If said backwards, there is double the amount of blue paint as there is yellow paint.

In the first two columns, yellow paint is blue paint divided by 2.

4/2 = 2

8/2 = 4

In the last column, blue paint is yellow paint times 2.

16 X 2= 32

All of the ratios yellow to blue are:

2 to 4

4 to 8

8 to 16

16 to 32

The attendance at a baseball game was 400 people. Adult seats sold for $15 and children seats sold for $10. Total ticket sales w

Natasha_Volkova [10]

Answer:

112 adult and 288 children

Step-by-step explanation:

x= adult seats

y= children seats

15x + 10y = 4560

x + y = 400 --> y=400-x

so plug 400-x for y in the other equation

15x + 10(400-x)= 4560

now solve this equation

15x + 10(400-x)= 4560 --> 15x + 4000-10x= 4560 --> 15x -10x = 560 --> 5x=560 --> x = 560/5 --> x= 112

now plug in 112 for this equation (x+y=400) --> 112+y=400 --> y= 288
