Answer:
Is C
Step-by-step explanation:
You can use the similarity approach of these two triangles CBD and CAE
as a result:
so:
? = 6x^2 / 10 = 0.6 x^2
and the fact of:
"The
segment connecting the midpoints of two sides of a triangle is parallel to the
third side and equals its half length"
so:BD = 0.5 AE 10 = 0.5 * 2x >>> x= 10
Back to:
? =0.6 x^2 = 0.6 * 10^2 = 0.6 * 100 = 60
AHope that helps
Answer:
250 students
Step-by-step explanation:
Let the number of sixth grade students be represented by = x
We were told that:
At a school, 40% of the sixth-grade students said that hip-hop is their favorite kind of music. 100 sixth-grade students prefer hip hop music.
Hence:
40% of x = 100
40/100 × x = 100
40x/100 = 100
Cross Multiply
40x = 100 × 100
x = 10000/40
x = 250
The number is sixth-grade students is 250 students
