The simplest form of Sin 30° x tan 60° is √3/2 or sin  60° or cos 30°.

What are trigonometry ratios?

Trigonometric By definition, ratios are the values of all trigonometric functions based on the right-angled triangle's side ratio. The trigonometric ratios of a given acute angle are the ratios of the sides of a right-angled triangle with respect to that angle.

Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).

Given that the trigonometry function is

sin 30° x tan 60°

Putting sin 30° = 1/2 and tan 60° = √3

=  (1/2) ×√3

=  (1/2) ×(√3/1)

Now multiply the denominators and numerators:

= √3/2

Putting √3/2 = sin 60°

= sin 60°

Answer:

1/5 of 1,212

Step-by-step explanation:

Note that 25% = 1/4 and 30% = 3/10.

The least value is achieved when we take the smallest fraction, which is 1/5.

Answer:

1/5 of 1212 is the smallest value

Step-by-step explanation:

if we convert 25% to a fraction we have 1/4

if we convert 30% to a fraction we have 3/10

now we convert each of the four fractions into equivalent fractions using lowest common denominator of 60

1/3 = 20/60

1/5 = 12/60

1/4 = 15/60

3/10 = 18/60

the smallest fraction is 12/60, or 1/5

therefore 1/5 of 1212 is the smallest value

Given that the side lengths of the ramp are 10 feet, 2.5 feet, and 10.5 feet.

We know that for making a right angle A Pythagoras triplet must follow

So, a² + b² = c²

Where a, b, c are the lengths of the triangle and a, b <=c

So, on applying the above formula

We have,

2.5² + 10² = 10.5²

6.25 + 100 = 110.25

But 106.25 is not equal to 110.25

The labeled quadrants in the standard xy coordinate plane is Quadrant II

What is Quadrants?

The intersection of the x-axis (the horizontal number line) and the y-axis in the cartesian system divides the coordinate plane into four equal pieces (the vertical number line). Because each of these four areas occupies a quarter of the entire coordinate plane, they are collectively referred to as quadrants.

Concept:

The x and y coordinates are both positive in quadrant I. In quadrant II, the x and y coordinates are oppositely positive. The x and y coordinates are both negative in quadrant III. The x-coordinate is positive and the y-coordinate is negative in quadrant IV.

The origin, or the point where the x- and y-axes connect, is where both the x and y coordinates are zero (0, 0).

The point is in the first quadrant if both x and y are positive. If both x and y are negative, the point will be in the second quadrant. In the third quadrant if both x and y are negatives, the point is located.

Answer: Frank has to pay 56,250 dollars

Step-by-step explanation:  If Frank's repair costs 55% of the original price, that means he'll have to pay 123,750 dollars because 55% of 225,000 is 123,750. But he doesn't have to pay that amount because the car insurance is paying 30% of 225,000 which is 67,500 dollars. So the car insurance is paying 67,500 dollars out of the 123,750 dollars in damage. So you'll have the subtract 123,750 by 67,500 which is 56,250 dollars.

Answer:

b. r = 18%

Step-by-step explanation:

0.3(0.82)^x:

0.3(0.82)^x:

The 0.82 is getting affected since it is raised to the power of x

Hence, for every iteration of x, the object is becoming 82% of itself.

100%-82%=18%

r = 18% ==> b

Option B is correct, 18% is the  rate of decay of the exponential function f(x) = 0.3(0.82)ˣ

A relation is a function if it has only One y-value for each x-value.

The exponential function f(x) = 0.3(0.82)^x can be written in the form f(x) = a(b)ˣ, where a = 0.3 and b = 0.82.

In an exponential function of the form f(x) = a(b)ˣ

the base b represents the rate of change.

If b is between 0 and 1, then the function represents exponential decay. The rate of decay r can be found using the formula:

r = (1 - b) x 100%

In this case, b = 0.82, so the rate of decay is:

r = (1 - 0.82) x 100%

= 0.18 x 100%

= 18%

Hence, option B is correct, 18% is the  rate of decay of the exponential function f(x) = 0.3(0.82)ˣ

Based on the rate of change, Zehra is buying 7 cans per week.

The rate of change gives the ratio between the change in one quantity to the change in another quantity.

Linear relationships have a constant rate of change and the rate of change is usually represented as the slope or gradient.

For instance, the number of cans changed from 29 to 57, a difference of 28, as the number of weeks changed from 5 to 9, a difference of 4.

The rate of change can be expressed as 28/4 or 7.

The number of cans after 5 weeks = 29

The number of cans after 9 weeks = 57

The change in weeks = 4 (9 - 5)

The change in the number of cans = 28 (57 - 29)

The rate of change = 7 (28/4)

Thus, we can conclude that Zehra buys 7 cans weekly.

z-score of a value is  -5.96

What is z-score in binomial distribution?

The Z score represents the number of standard deviations above or below the mean. The Z score of the mean is 0 by definition.

What is Probability?

The area of mathematics known as probability explores potential outcomes of events as well as their relative probabilities and distributions.

Given,

A random variable, let's call it X, has parameters that fit the Binomial distribution: n (number of trials) = 50 and p (success probability) 0.76.

We must ascertain the z-score (Z) of the value 20 =  that this random variable X has chosen.

Now, for a random variable, say X, its z-score (Z) is defined as ,

Z = (X - mean of X)/ Standard deviation of X

A binomial random variable with the parameters once more n and p, its mean is given as np and its standard deviation is given as [tex]\sqrt{n*p*(1-p)}[/tex]

The standard deviation of X is provided as [tex]\sqrt{50*0.76*0.24}[/tex] = [tex]\sqrt{9.12}[/tex] = 3.0199933  while the mean of X is given as 50*0.76 = 38.

Therefore, the required z-score (Z) for X = 20, is given as,

Z = 20-38/3.0199933

Z= -5.9602781238

Z= -5.96 that is the necessary z-score.

As AB is the perpendicular bisector of IK so we conclude that the right option is AJ=BJ.

A precise drawing in which a line is split in half by another line that is at a 90-degree angle to the original line is known as a perpendicular bisector. To divide into two equal portions is to bisect. When two lines intersect at a straight angle, they are perpendicular.

A line that precisely divides a line segment connecting two locations in half at a 90 degree angle is known as a perpendicular bisector. Finding the midpoint and negative reciprocal of two points, then entering these solutions into the equation for a line in slope-intercept form, will get the perpendicular bisector of the two points.

Option J can not be true as A can not be the midpoint of IK as A is not on IK.  Because J is on the IK as AB is the perpendicular bisector of IK, dividing or cutting it i,e IK into two equal segment parts. Hence, J is assumed as the midpoint of IK.

Option H i.e IJ = JK can not be true because AJ does not necessarily equal to BJ.

Option G i.e m∠IAJ  also does not true necessarily true. The reason is simple i.e AJ is arbitrary.

The smallest number of bags to cover the circular field is 3.0 pounds.

Area of a circle.

A circle is a shape that has a curved sides referred to as a  circumference. Its area can be determined by;

Area of a circle = [tex]\pi r^{2}[/tex]

where r is the radius of the circle

So that,

the radius of the circular field = 290/ 2

                                                 = 145 feet

The area of the circular field =  [tex]\pi r^{2}[/tex]

                                              = 22/7 x (145)(145)

The area of the circular field = 66078.57 square feet.

Given a bag has a capacity of 50 pounds, and that one pound of grass seed covers about 400 square feet.

Then,

total pounds in a bag = 50 x 400

                                    = 20000 pounds

the number of bags of grass seed needed = 66078.57 / 20000

                                                        = 3.304

The number of bags of grass seed needed = 3.30

What is 30-60-90 traingle?

The 30-60-90 triangle is cut straight through the middle along its altitude, like one half of an equilateral triangle. Its name is derived from its three angles of 30 degrees, 60 degrees, and 90 degrees. Any triangle with angles of 30-60-90 will look like this: The hypotenuse is always twice as long as the shortest leg, and the length of the long leg can be calculated by multiplying the short leg by the square root of three. The shortest leg is across from the 30-degree angle.

By 30-60-90 triangle rule,

Side across 60° angle = x

Hypotenuse side = 2x= 15

Side across 30° angle = x√3

By solving,

2x= 15

x= 7.5cm

So side across 60° angle= 7.5 cm

Side across 30° angle = 7.5×√3
