Answer:
17.11 meters
Step-by-step explanation:
You are using trigonometry in this problem.
The height of the flagpole represents the side <u><em>opposite</em></u> the given angle.
The base of the triangle is given as 19 meters and represents the side <u><em>adjacent</em></u> to the given angle.
Out of the main trigonomentric functions (sine, cosine, and tangent), only tangent uses both the opposite and adjacent sides.
Tan(angle) = opposite / adjacent
If we plug in what we know into that equation: <em>tan(42 degrees) = h / 19</em>
This means that <em>your answer = 19 * tan(42) = 17.11</em> meters
Answer:
Sybil may have confused the units, since 65 centimetres is 6.5 meters The correct length of the desk in meters is 0.65 because a centimetre is 0.01 of a meter.
Step-by-step explanation:
Her desk is actually 65 centimetre long . She made an error and conclude the length of her desk is 6.5 meter long. She made a mistake in her conversion .
1 centimetre = 0.01 meters
65 centimetres = ? meters
cross multiply
65 × 0.01 = 0.65 meters
A centimetre is equal to 0.01 meters. Therefore, using that conversion rate 65 centimetres will evaluate to 0.65 meters.
The actual length of her desk in meters is 0.65. She made an error when converting her desk length from centimetres to meters.
Answer: 56 oranges
Step-by-step explanation:
In a sample of 25 oranges, 2 oranges weigh 5 ounces.
Proportionally represented, that would be:
= 2 / 25
Assuming the 25 is representative for all 700 oranges, the number of oranges that can be expected to weigh 5 ounces from the shipment is:
= Proportion of 5 ounces oranges from sample * Total number of oranges
= 2/25 * 700
= 56 oranges
Step-by-step explanation:
Let Jim earned $ x
Therefore, Debbie earned = $(x + 1600)
According to the given information:
Thus, Jim`s earning = $2800
Debbie`s earning = 2800 + 1600 = $4400
