Answer:
8 feet.
Step-by-step explanation:
If we know the shadow (30 ft) of a tower (15 ft), we can use use the ratio
where 'x' is the height of the telephone pole. Cross multiply, and we get the equation . The rest of the problem is pretty straightforward, we divide both sides by 30 to find x. In the end, you will find that the height of the telephone pole is 8 feet.
Hope this helped!
Answer:
ABQ = 139
BCR is the same as QBC since they are alternate interior angles
BCR = 41
Step-by-step explanation:
CBQ and SCB are same side interior angles so they add to 180
2a-9 + 5a +14 = 180
Combine like terms
7a +5 = 180
Subtract 5 from each side
7a = 175
Divide by 7
7a/7 = 175/7
a = 25
ABQ is the same as SCB since they are corresponding angles so
ABQ = SCB = 5a+14 = 5*25+14 = 125+14 = 139
BCR is the same as QBC since they are alternate interior angles
BCR = QBC = 2a-9 = 2*25 -9 = 50-9 = 41
1/3 * 7/9 kg = (1 * 7)/(3 * 9) kg = 7/27 kg
He used 7/27 kg of sugar.
