Answer:
x = 36.27
Step-by-step explanation:
By using the steps to find sin θ backwards, we can find x, the hypotenuse.
sin θ = [tex]\frac{opposite}{hypotenuse}[/tex] or side [tex]\frac{a}{c}[/tex] (as seen in my example picture).
We already know the value for sin (α), which is 32° because its given. The opposite side (a) is 20 and the hypotenuse side (c) is x which are both also given.
So the equation now looks like:
sin 32° = [tex]\frac{20}{x}[/tex]
Don't solve for the sin 32 yet! First, we have to isolate the variable.
To get rid of the x in the denominator you have to multiply both sides by x:
( sin 32 ) · x = ( [tex]\frac{20}{x}[/tex] ) · x
( sin 32 ) x = 20
Then, you have to divide both sides by sin 32 to get x by itself:
(( sin 32 ) x ) ÷ ( sin 32 ) = 20 ÷ ( sin 32 )
x = 20 ÷ ( sin 32 )
Lastly, you have to use a calculator to find 20 ÷ ( sin 32 ), and it should give you 36.2695543766.
The question asks you to round to 2 decimal places so:
x = 36.27

73% of the model is shaded, 146/200 is the equivalent ratio.0.73 is the equivalent decimal and 146/200 is the equivalent fraction
What is Fraction?A fraction represents a part of a whole.
Given,
A grid model with 100 squares. 73 squares are shaded.
We need to find percent of the model is shaded
As there are 100 grids with 73 shaded.
73% of the model is shaded
Now let us find equivalent ratio of 73/100
Multiply numerator and denominator 2
73/100×2/2
146/200
146/200 is the equivalent ratio.
73/100=0.73 is the equivalent decimal.
146/200 is the equivalent fraction.
Hence,73% of the model is shaded, 146/200 is the equivalent ratio.0.73 is the equivalent decimal and 146/200 is the equivalent fraction.

working alone, kali can pick forty bushels of apples in 15 hours,l. One day her friend Natalie helped her and it only took 6 hours. How long would it take Natalie to do it alone.
(please help I'm struggling)
Answer:
The time it will take Natalie to pick the forty bushels alone is 10 hours
Step-by-step explanation:
The time it takes Kali to pick forty bushels of apples alone = 15 hours
The time it takes Kali and Natalie to pick forty bushels = 6 hours
The rate at which Kali picks bushels = 40/15 bushels per hour = 8/3 bushels per hour
Let x represents the rate at which Natalie picks bushels, we have;
8/3 × 6 + x × 6 = 40
x × 6 = 40 - 8/3 × 6 = 24
x = 24/6 = 4
Therefore;
The rate at which Natalie picks the bushels of apples = 4 bushels/hour
The time it will take Natalie to pick the forty bushels alone = (40 bushels)/(4 bushels/hour) = 10 hours.
An architect built a scale model of a shopping mall. On the model, a circular fountain is 21 inches tall and 17.5 inches in diameter. If the actual fountain is to be 6 feet tall, what will its diameter be?
Answer:
The diameter is 5ft
Step-by-step explanation:
Given
[tex]Height : Diameter = 21\ in: 17.5\ in[/tex]
Required
Determine the diameter when the height is 6ft
Recall that the scale is a ratio of height to diameter;
So 6ft height can be represented on the following scale model;
[tex]Height : Diameter = 6ft : x[/tex]
Convert to fraction
[tex]\frac{Height}{Diameter} = \frac{6}{x}[/tex] ---- (1)
Recall that:
[tex]Height : Diameter = 21\ in: 17.5\ in[/tex]
Convert to fraction
[tex]\frac{Height}{Diameter} = \frac{21 }{17.5}[/tex] ---- (2)
Equate (1) & (2)
[tex]\frac{6}{x}= \frac{21 }{17.5}[/tex]
Cross Multiply
[tex]21 * x = 6 * 17.5[/tex]
[tex]21x = 105[/tex]
[tex]x = 105/21[/tex]
[tex]x = 5[/tex]
Hence, the diameter is 5ft

A binomial event has n = 35 trials. The probability of success for each trial is 0.45. Let x be the number of successes of the event during the 35 trials. What are μx and σx? (4 points) a)15.75 and 3.1996 b)15.75 and 2.9432 c)19.25 and 2.9432 d)19.25 and 3.1996 e)30 and 2.9432
Answer:
b)15.75 and 2.9432
Step-by-step explanation:
The computation of the mean and the standard deviation is shown below:
The mean of a binomial distribution is:
[tex]\mu[/tex] = np
And the standard deviation is
[tex]\sigma[/tex] = √(npq)
where,
n = 35,
p = 0.45,
and q = 1 - 045 = 0.55
Now mean is
= 35 × 0.45
= 15.75
And, the standard deviation is
= √(35 × 0.45 × 0.55)
= 2.9432
Hence, the correct option is B.

Answer:
x = ± 6i
Step-by-step explanation:
Given
x² + 27 = - 9 ( subtract 27 from both sides )
x² = - 36 ( negative value indicates the solutions are complex )
Take the square root of both sides
x = ± [tex]\sqrt{-36}[/tex] = ± 6i

Ella made a checker board. Each individual square has a side with a length of x + 3. Find the area of the ENTIRE board in terms of x if each side of the board is made up of 6 congruent squares.
Answer:
Total area of board = 36x² + 324 + 216x
Step-by-step explanation:
Given:
Side of square = x + 3
Total number of square = 6 x 6 = 36
Area of each square = Side x Side
Area of each square = (x + 3)²
Area of each square = x² + 9 + 6x
Total area of board = 36[Area of each square]
Total area of board = 36[x² + 9 + 6x]
Total area of board = 36x² + 324 + 216x
