Answer:
x(less than or equal to)5
Step-by-step explanation:
add 10 to both sides
20x-10(less than or equal to) 90
+10 +10
20x (less than or equal to) 100
divide by 20 to isolate the variable
20x(less than or equal to) 100
/20 /20
x (less than or equal to) 5
Answer:
Step-by-step explanation:
If the triangle is equilateral :
2x +y/2 = 5x/3+y + ½ = 2/3x +2y +5/2
so the perimeter is : P = 3(2x +y/2) or 3(5x/3+y + ½) or 3(2/3x +2y +5/2)
the simplest is : P = 3(2x +y/2)
P = 6x + (3y)/2
C = 2πr or C = πd
Diameter d = 57 cm
C = πd
C = π*57 = 57π
C ≈ 57 * 3.14159 = 179.07063
Exact circumference is 57π cm or
≈ 179.07 cm.
Answer:
it b
Step-by-step explanation:
The sample is based on the first 25 parents dropping off actors during theater rehearsal hence the sampling method is non random and biased.
A non random sample refers to a sampling method that is not based on chance alone. A biased sampling is one in which some members of the population are more likely to be selected thereby excluding the others.
Since the sample is based on the first 25 parents dropping off actors during theater rehearsal, the sampling method is non random and biased.
