If the mountain is 1,200 feet tall, find the length of the ski lift
Answers
Step-by-step explanation;
By an online search, i found that the sky lift
rises at an angle of 20.75 degrees.
Then we can think on a triangle rectangle, such
that:
One cathetus is 1200ft, this is the opposite
cathetus to the angle of 20.75°
The length of the ski lift would be the
hypotenuse of this triangle rectangle.
Then we can use the relationship:
Sin(a) = opposite cathetus/hypoteuse.
such that:
a = 20.75°
opposite cathetus=1200ft
then:
sin(20.75°) = 1200ft/hypotenuse
hypotenuse =1200ft/sin(20.759) =3.387.05 ft
The length of the sky lift is 3.387.05 ft

explain why 0.3 x 0.9 doesn't equal 2.7
Answers
Answer:
equals 0.27
because of the 0
Step-by-step explanation:
When multiplying decimals 0.3 x 0.9, the correct product is 0.27 not 2.7.
Due to the fact that multiplying decimals requires taking into account the place value of each decimal digit, the product of 0.3 times 0.9 does not equal 2.7.
To reach the result in the hundredth place when multiplying 0.3 by 0.9,
and, multiply the tenth place (0.3) by the tenth place (0.9).
So, 0.3 x 0.9 = 0.27
The product is 0.27, not 2.7.
When the entire numbers 3 and 9 are multiplied, gives number 27.
When the decimal places are ignored, gives 2.7.
Thus, the correct product is 0.27, not 2.7.

There are 25 students in Laura's class, and 21 of the students went on the class trip to the zoo. What percentage of students went on the class trip?
(Explain for brainlist)
Answers
Answer: 84%
Step-by-step explanation:
A percentage is really a fraction with the denominator of 100. That means we can take the fraction of the students that went to the field trip (21/25) and make the denominator to 100. Since 25x4 is 100 we can do that but we also must do 21x4 because what you do to the top of the fraction you must do to the bottom. So you'd get 84/100 which is 84%
\(\frac{21}{25}\) ×\(\frac{4}{4} =\frac{84}{100}\)

5. Use 3.14 for Pi to estimate the area of a circle. The diameter is given. Round your answer to the nearest hundredth if necessary.
Answers
Answer:
Step-by-step explanation:
248.85
Answer:
221.47m^2
Step-by-step explanation:
To estimate the area of a circle, we can use the formula:
Area = π x (radius)^2
Since the diameter of the circle is given as 16.8m, we can first find the radius by dividing the diameter by 2:
radius = diameter / 2 = 16.8m / 2 = 8.4m
Now, using the given value of pi as 3.14, we can estimate the area of the circle as:
Area = π x (radius)^2
= 3.14 x (8.4m)^2
= 3.14 x 70.56m^2
= 221.47m^2 (rounded to the nearest hundredth)
Therefore, the estimated area of the circle is approximately 221.47 square meters.

\(\frac{1}{6} + \frac{7}{12} - 2x = \frac{8}{3} x (\frac{1}{2} - x)\)
\(\frac{1}{6} + \frac{7}{12} - 2x = \frac{4}{3} - \frac{8}{3}x\)
Step 2:
\(\frac{1}{6} + \frac{7}{12} - 2x = \frac{4}{3} - \frac{8}{3}x\)
\(\frac{3}{4} - 2x =\frac{4}{3} - \frac{8}{3}x\)
Step 3:
\(\frac{3}{4} - 2x =\frac{4}{3} - \frac{8}{3}x\)
\(9 - 24x = 16 - 32x\)
Step 4:
\(9 - 24x = 16 - 32x\)
\(9 - 24x + 32x = 16\)
\(-24x + 32x = 16 - 9\)
Step 5:

\(8x = 16 - 9\)

In the rectangle below, the line MN cuts the rectangle into two regions. Find x, the length of segment NB, so that the area of the quadrilateral MNBC is 40% of the total area of the rectangle.
Answers
The length of segment NB is 0.833
Finding x, the length of segment NBFrom the question, we have the following parameters that can be used in our computation:
The rectangle
The area of the rectangle is
Area = (20 + x) * 10
The area of MNBC is
Area = 1/2 * 10 * (x + 20 + x - 5)
Area = 5(2x + 15 )
The area of the quadrilateral MNBC is 40% of the total area of the rectangle
So, we have
5(2x + 15) = 40% * (20 + x) * 10
5(2x + 15) = 4* (20 + x)

(-7)6 can be written as (-7)•(-7)•(-7)•(-7)•(-7)•(-7)
Now, using the rule that says minus times minus is plus, (-7)6 can be written as (49)•(49)•(49) which in turn can be written as (7)•(7)•(7)•(7)•(7)•(7) or 76 which is positive.

Substituting the given values, we have:
125.6 = 3.14 x r^2 x 10
Dividing both sides by 3.14 x 10, we get:
r^2 = 4
Taking the square root of both sides, we get:
r = 2 cm
Therefore, the radius of the cylinder is 2 cm.

Barbara runs a lemonade stand to raise money for Barton Children's Hospital. Last weekend, she made 8 liters of lemonade to sell. Saturday was rainy, so she only sold 8 glasses. The weather was better on Sunday, so she sold 24 glasses. If each glass holds 200 milliliters, how many liters of lemonade does Barbara have left?
PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
1.6 liters of lemonade
Step-by-step explanation:
There are 1000 milliliters in one liter so she made 8000 milliliters of lemonade
Next we have to figure out how many milliliters of lemonade she sold each day:
Saturday: 200 milliliters of lemonade in a glass * 8 glasses = 1600 milliliters of lemonade sold
Sunday: 200 milliliters of lemonade in a glass * 24 glasses = 4800 milliliters of lemonade sold
1600 + 4800 = 6400 total milliliters of lemonade sold
Since there are 1000 milliliters in one liter, we have to divide 6400 by 1000:
6400 ÷ 1000 = 6.4 liters
Lastly, we have to subtract 6.4 from 8:
8 - 6.4 = 1.6 liters of lemonade
