Answer:
If this is the complete question them the answer is 1250 m²
Step-by-step explanation:
the pool in the drawing is 15x7.5 and the scale is 3/1000 so if the size in the drawing is 3 then the actual is 1000.
x=15*1000/3=5000cm which would be 50m
x=7.5*1000/3=2500cm which is 25m
the actual area of the pool is 50*25=1250 m²
When u find the volume , u multiply the length and width and height together
The laws of sines is already indicated in the provided images.
1. sin20/3.3 = sinC/5.4
Thus, angle C is 34.03 degrees. To find angle B: 180 - 20 - 34.03 = 126 degrees. Using the law of sines,
sin20/3.3 = sin(126)/b
b = 7.8 units
From this answer, we can already tell that the answer is letter C: <span>3 units and 7.8 units.
2. Angle J = 180 - 120 - 40 = 20 degrees. Then,
sin(20)/2 = sin(120)/k
k = 5.1 units</span>
Answer:
6) B
7) D
Step-by-step explanation:
6)
The surface area of a cylinder is 2 * pi * r * (r + h)
SA = 2 * 3.14 * 3.6 * (3.6 + 8.5) = 2 * 3.14 * 3.6 * 12.1 = 273.6 cm^2
7)
The volume of a cylinder is pi * r^2 * h
V = 3.14 * (3.6)^2 * 8.5 = 345.9 cm^3
We conclude that the closest measure to 73 hectograms is 16.09 pounds,
<h3>
Which of the following are approximately equal to 73 hectograms?</h3>
First, notice that:
1 hectogram = 100 grams.
Now let's write all of the given measures in grams, and let's see which one is approximately equal to 73 hg.
Remember that:
1 ounce = 28.3 grams.
1 pound = 453.6 grams.
Then the given measures are:
- 257.5 oz = (257.5)*28.3 grams = 7,287.25 grams.
- 0.73 lb = 0.73*(453.6 grams) = 331.128 grams.
- 16.09 oz = (16.09)*28.3 grams = 455.347 grams.
- 16.09 lb = (16.09)*453.6 grams = 7,298.4 grams
The one that is closest to 73 hectograms is the last measure, that when written in hectograms are:
7,298.4 grams = (7,298.4/100) hectograms = 7.298 hectograms.
We conclude that the closest measure to 73 hectograms is 16.09 pounds.
