A random sample from the 6th and 7th grade student population was taken to determine which clubs were the most popular. 6th Grade: Yearbook 10; Student Council 24; Jump Rope 6
7th Grade: Yearbook 18; Student Council 20; Jump Rope 2

What percent of 6th graders are involved in the yearbook club?

your answer is  

d.

196.5 m2

step-by-step explanation:

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
