Long distance calls cost $0.17 each. Linda use her card only to make a long distance call. Assuming she made a total of x minutes of long distance calls, the cost would be $0.17x. The amount remaining on her card will be

30 - 0.17x

if the remaining credit on her card is $22.52, the number of minutes,x that the call lasted will be

22.52 = 30 - 0.17x

0.17x = 30 - 22.52

0.17x = 7.48

x = 7.48/0.17 = 44

On Tuesday the temperature is 1 ºC. By Wednesday it has dropped to –2 ºC. The temperature drops by twice as much from Wednesday

Finger [1]

Answer: $-8^{\circ}C$

Step-by-step explanation:

Given

The temperature on Tuesday is $1^{\circ}C$

Temperature drops to $-2^{\circ}C$ on Wednesday

Net drop in temperature $1-(-2)=3^{\circ}C$

The temperature drops twice from Wednesday to Thursday

$\Delta T=2\times 3=6^{\circ}C$

Temperature on Thursday

$\Rightarrow -2-6=-8^{\circ}C$

ABC High School is debating whether or not to write a policywhere all students musthave uniforms and wear them during school hou

larisa [96]

If 45% don't want uniforms, it means that 45 out of 100 students don't want them, so the probability is 45/100 = 9/20

And 55% want unifrms, so the probability = 55/100 = 11/20
