Answer 1

The ratio of any two right-angled triangle sides may be used to compute trigonometric ratios.

How is trigonometric ratio rule calculated ?You may determine trigonometric ratios by either utilising the provided acute angle or by figuring out the ratios of the right-angled triangle's sides. The formulae for trigonometric ratios are sin = Perpendicular/Hypotenuse and cos = Base/Hypotenuse.Triangle side length ratios are known as trigonometric ratios. In trigonometry, these ratios show how the ratio of a right triangle's sides to each angle. Sine, cosine, and tangent ratios are the three fundamental trigonometric ratios. The sin, cos, and tan functions may be used to obtain the other significant trig ratios, cosec, sec, and cot.The ratio of any two right-angled triangle sides may be used to compute trigonometric ratios. The Pythagorean theorem may be used to evaluate the third side.

Given details :

The measurement of the given angle is 30 degree.

Here we use trigonometric ratio rule which is sin theta= opposite/hypotenuse

Here theta = 30 degree, opposite =7 and hypotenuse =a

So we get

sin 30 = 7/a

a= 7/sin 30

And value of sin 30 = 0.5

So we get , a = 7/0.5 = 14

So the value of a is 14 .

The lowest integer value m can take in the inequality 7m + 5 > 49 - 3m is 5.

How to solve inequality?

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

In other words, Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤.

Therefore, let's solve the inequality for the lowest integer value of m

7m + 5 > 49 - 3m

add 3m to both sides of the inequality

7m + 5 > 49 - 3m

7m + 3m + 5 > 49 - 3m + 3m

10m + 5 > 49

subtract 5 from both sides of the inequality

10m + 5 > 49

10m + 5 - 5 > 49 - 5

10m > 44

Answers

The Cp and Cpk values indicate that the process is capable of meeting the specifications for relative humidity in the greenhouse.

What is relative humidity?

The amount of water vapor in the air as compared to the maximum amount that it can contain at a certain temperature is known as relative humidity. It is computed as a percentage by dividing the actual amount of water vapor in the air by the maximum amount of water vapor the air can contain at the same temperature, then multiplying the result by 100. For instance, if the air can hold 10 grams of water vapor at a certain temperature and there are only 5 grams of water vapor present, the relative humidity would be 50%. High relative humidity can be uncomfortable and promote the development of mold and other microorganisms.

How to solve?

The mean is (60+78+70+84+81+80+85+60+88+75)/10 = 76.8

The standard deviation is sqrt(((60-76.8)^2+(78-76.8)^2+(70-76.8)^2+(84-76.8)^2+(81-76.8)^2+(80-76.8)^2+(85-76.8)^2+(60-76.8)^2+(88-76.8)^2+(75-76.8)^2)/10) = 6.9

Cp = (85-65)/(66.9) = 0.56

Cpk = min((85-76.8)/(36.9), (76.8-65)/(36.9)) = min(0.86, 0.71) = 0.71

how much is 1kg of corn plus 1 cup of precooked corn ??​

Answers

Answer:

Step-by-step explanation:

It is not possible to accurately compare the weight of 1 kilogram of corn to 1 cup of precooked corn because the weight of the corn will change after it is cooked. Corn is composed of water, starch, and other nutrients, and the weight of the corn will change depending on how much water is retained in the kernels.

For example, 1 cup of uncooked corn kernels (about 168 grams) will yield about 1 1/4 cups of cooked corn (about 210 grams), while 1 cup of precooked corn (about 160 grams) will yield about 1 cup of cooked corn (about 160 grams).

Therefore, the weight of 1 kilogram of corn (about 1000 grams) is significantly greater than the weight of 1 cup of precooked corn (about 160 grams). It is not possible to accurately compare the weight of these two quantities because they are in different states (raw versus cooked) and have different densities.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the amount of petrol in Spain be = A

Let the amount of petrol in Wales be = B

Now , the total amount Sam paid for 18 Liters of petrol in Spain = 27 euros

1 euro = 0.85 pounds

So ,

Total amount Sam paid for 18 Liters of petrol in Spain = 27 x 0.85 pounds

Total amount Sam paid for 18 Liters of petrol in Spain = 22.95 pounds

So ,

The amount for 1 Liter of petrol in Spain = Total amount Sam paid for 18 Liters of petrol in Spain / 18

Substituting the values in the equation , we get

The amount for 1 Liter of petrol in Spain = 22.95 / 18

The amount for 1 Liter of petrol in Spain = £ 1.275

And ,

Now , the total amount Sam paid for 8 gallons of petrol in Wales = £ 40.80

1 gallon = 4.5 Liters

8 gallons = 4.5 x 8 Liters

8 gallons = 36 Liters

So ,

Total amount Sam paid for 36 Liters of petrol in Wales = £ 40.80

So ,

The amount for 1 Liter of petrol in Wales = Total amount Sam paid for 36 Liters of petrol in Spain / 36

Substituting the values in the equation , we get

The amount for 1 Liter of petrol in Wales = 40.80 / 36

The amount for 1 Liter of petrol in Wales = £ 1.13

£ 1.13  <   £ 1.275

Therefore , the amount for 1 Liter of petrol in Wales is less than the amount for 1 Liter of Petrol in Spain

Hence , The amount for 1 Liter of petrol in Wales is less than the amount for 1 Liter of Petrol in Spain

Answers

Answer:25$

Step-by-step explanation: 21$ is 84% of how much money Cho had last month. So we need to find 100%. You can use a proportion which makes it easier to solve in my opinion. The proportion is 21 over x = 84/100. x is the amount of money Cho had last month which we don't know. 84/100 is 84% out of 100% since any percent is always out of 100. If we cross-multiply and make the proportion into an equation. The equation: 84*x=21*100 which simplifies into 84x=2100. If you do 2100/84, you would get 25 which is x which is the amount of money Cho had last month.

A blimp is flying to cover a football game. The pilot sights the stadium at a 7° angle of depression. The blimp is flying at an altitude of 400 m. How many kilometers is the blimp from the point 400 m above the stadium?

Answers

To find the distance from the blimp to the stadium, we can use the tangent function and the information given in the problem. The tangent of an angle is defined as the ratio of the opposite side to the adjacent side in a right triangle. In this case, we can use the angle of depression to the stadium, the altitude of the blimp, and the distance from the blimp to the stadium to form a right triangle.

We can then use the tangent function to find the distance from the blimp to the stadium as follows:

tan(7°) = opposite/adjacent

opposite = tan(7°) * adjacent

opposite = tan(7°) * 400 m

opposite = 0.1214 * 400 m

opposite = 48.56 m

To convert this distance from meters to kilometers, we can divide the distance in meters by 1000, as follows:

Distance in kilometers = 48.56 m / 1000

Distance in kilometers = 0.0486 km

Therefore, the distance from the blimp to the stadium is approximately 0.0486 km.

Substituting the values of x we get,

y = -3 (-4) - 3 ⇒ 12 - 3 = 9

y = -3 (-2) - 3 ⇒ 6 - 3 = 3

y = -3 (0) - 3 ⇒ 0 - 3 = -3

y = -3 (2) - 3 ⇒ -6 - 3 = -9

Hence, the values of y are [tex]9,3,-3,-9[/tex].

One diamond in the safe deposit box is worth 12,000 if each of the other jewels are worth 2,160 how many total jewels are inside the box (including the diamond)

Answers

The total jewels that are inside the box will be 14160.

How to illustrate the expression?

It should be noted that expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.

Since one diamond in the safe deposit box is worth 12,000 if each of the other jewels are worth 2,160. The total jewels that are inside the box will be:

= 12000 + 2160

= 14160

A square is inscribed in a circle. Write the area of the square as a function of the radius.

Answers

Area will be 2[tex]r^{2}[/tex]

What is area?

Area is the entire amount of space occupied by a flat (2-D) surface or an object's form.

Given radius of circle is r

Then area of circle=π[tex]r^{2}[/tex]

The diagonal of the square is comparable to the diameter (2r) of the circle since two opposing corners of the square contact it.

Now, we will set up Pythagoras' Theorem to determine one side of the square:

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

Since it is a square a=b which means all  the sides are same

∴2[tex]a^{2}[/tex] = [tex]c^{2}[/tex]

We know c, which is 2r, the diagonal.

∴2[tex]a^{2}[/tex] = [tex](2r)^{2}[/tex]

⇒[tex]a^{2}[/tex] = 2[tex]r^{2}[/tex]

We can leave it as [tex]a^{2}[/tex]

since a is one side of the square and [tex]a^{2}[/tex] would be the area of the square.

So the area of the square =2[tex]r^{2}[/tex]

Multiplications of 2 matrices

Answers

The product of matrix A and matrix B is matrix C

a)  [tex]C = \begin{pmatrix}23\end{pmatrix}[/tex]

b) [tex]C = \begin{pmatrix}5\end{pmatrix}[/tex]

What is multiplication of matrices?

The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. The first matrix must have the same number of columns as the second matrix has rows. The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix

Given data ,

a)

Let the first matrix be A

The value of A is

[tex]A = \begin{pmatrix}2&3\end{pmatrix}[/tex]

The value of second matrix B is

[tex]B = \begin{pmatrix}4\\ \:5\end{pmatrix}[/tex]

Now , the product of matrix A and matrix B is matrix C

The value of matrix C is

[tex]C = \begin{pmatrix}2&3\end{pmatrix}\begin{pmatrix}4\\ 5\end{pmatrix}[/tex]

On simplifying the value of matrix C , we get

[tex]C = \begin{pmatrix}2\cdot \:4+3\cdot \:5\end{pmatrix}[/tex]

[tex]C = \begin{pmatrix}23\end{pmatrix}[/tex]

Therefore , the value of matrix C is [tex]C = \begin{pmatrix}23\end{pmatrix}[/tex]

b)

Let the first matrix be A

The value of A is

[tex]A = \begin{pmatrix}1&2\end{pmatrix}[/tex]

The value of second matrix B is

[tex]B = \begin{pmatrix}-3\\ \:4\end{pmatrix}[/tex]

Now , the product of matrix A and matrix B is matrix C

The value of matrix C is

[tex]C = \begin{pmatrix}1&2\end{pmatrix}\begin{pmatrix}-3\\ 4\end{pmatrix}[/tex]

On simplifying the value of matrix C , we get

[tex]C =\begin{pmatrix}1\cdot \left(-3\right)+2\cdot \:4\end{pmatrix}[/tex]

[tex]C = \begin{pmatrix}5\end{pmatrix}[/tex]

Therefore , the value of matrix C is [tex]C = \begin{pmatrix}5\end{pmatrix}[/tex]

Hence , the matrix multiplication is

The product of matrix A and matrix B is matrix C

a)  [tex]C = \begin{pmatrix}23\end{pmatrix}[/tex]

b) [tex]C = \begin{pmatrix}5\end{pmatrix}[/tex]
