Answer:
<u>(2) x </u>
<u> 4</u>
Step-by-step explanation:
Given the sqrt(x), x zero
So, given sqrt(x -4), x -4 0
Now solve for x
x - 4 0
x 4
Answer:
Tia cut a 4-meter 8-centimeter wire into 10 equal pieces. for Jay 10 quarts would be the answer. Step-by-step explanation: He needs x quarts for the inside painting and x + 19 quarts for the outside. These two measures add up to 2x + 19, which equals 107 (quarts) total. The last one is tring A is 35 cm long, string B is 5 times as long as string A, then string B is 35·5=175 cm long. In total both strings have length 35+175=210 cm. The total length of string needed for 17 identical decirative bottes is cm that is 35.7 m.
10 red
8 blue
2 green
Total number = 20
Probability that Gina takes a red pen = number of red pens divided by the total = 10/20 = 0.5 = 50%
If she repeats the event, the second time the probability is the same: 0.5 = 50%
Probability of two events = probability of the first one multiplied by the probability of the second = 0.5 x 0.5 =0.25 = 25%
Answer:
Probability = 0.25 = 25%
