Radian measure by diving the length of an arc by the radius of the circle. Therefore, 1 radian is the angle subtended to the center of a circle by an arc length equivalent to the radius of a circle.
radius is 48 millimeters and the length of an arc is 36π millimeters
Hence, radians =S/r
= 36 π/48 if we take π as 3.14
= 36 ×3.14 /48
= 2.355 radians

Answer:

LM+MN=LN

3x-5+x+7=17

4x=17+5-7

4x=15

x=15/4=3.75

LM= 3x-5=3*3.75-5=6.25

Convert the equation to slope-intercept form: 2y = x + 8

nalin [4]

Answer:

y=(1/2)x+4

Step-by-step explanation:

Since slope-intercept form is y=mx+b, all we need to do is divide both sides by 2:

2y=x+8

y=1/2x+4

Thus, the equation would be y=1/2x+4

Tickets prices for a science museum are $18 for adults and $12 for students. If $162 is collected from a group of 12 people, how

riadik2000 [5.3K]

X=number of adults, y= number of students

x+y=12
18x+12y=162

You can simplify the second equation by dividing by six: 3x+2y=27
Rearrange the first equation: y= 12-x. Plug y into the simplified second equation:

3x+2(12-x)=27
3x-2x+24=27
x=3.

Plug the now known x value into y=12-x. So y= 9.
Therefore, there are 3 adults and 9 students.
