Answer:
<em>Shadows are produced when light hits an opaque object which prevents the light beams from passing through. When an object blocks the light's path, then darkness appears on the other side. This darkness is called a shadow. The sun is a source of light that when hits an object causes shadows.</em>
Answer:
<em><u>x = -</u></em><em><u>1</u></em><em><u>0</u></em>
Step-by-step explanation:
-9x + 7 = -6x + 37
-9x + 6x = 37 - 7
-3x = 30
<u>x = </u><u>-</u><u>1</u><u>0</u>
Answer:
C is the answer
Step-by-step explanation:
2pir = 3pi
r = 3/2
area is pir^2
pi(3/2)^2= 9/4 pi cm^2
Answer:
<u>The correct answer is 5/24 or 0.21</u>
Step-by-step explanation:
1. Let's review all the information given to answer the question correctly:
Science class in seventh grade = 4 girls and 4 boys
Science class in eighth grade = 5 girls and 7 boys
2. What is the probability that both students selected for the competition are girls, a seventh grader and an eighth grader?
These are independent events, therefore:
Probability of two independent events = Probability of A * Probability of B
Probability of both students selected for the competition are girls = 4/8 * 5/12
Probability of both students selected for the competition are girls = 20/96 = 5/24
<u>The correct answer is 5/24 or 0.21</u>
