Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

The sine ratio is defined as:

[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

It's required to calculate the sine of angle C. The opposite leg to angle C is 16 and the hypotenuse is 20, thus:

[tex]\displaystyle \sin C=\frac{16}{20}[/tex]

The last choice is correct

Answer:

The numbers are

22 and 23  to solve a problem like this, we need to read and define as we go. Let me explain. So we know that there are two consecutive integers. They can be

x and x+1

. Since their consecutive, one has to be 1

number higher (or lower) than the other. Ok, so first we need "seven times the larger"( 7x+1)

Next, we need to "minus three times the smaller" 7(x+1)−3x

Is equal to " 957(x+1)−3x=95

Alright! There's the equation, now we just need to solve for  x! First we are going to get everything on one side and distribute the 7=7x+7−3x−95=4x−88

Pull out a

=4(x−22)Now that we have two terms, we can set them both equal to

0 and solve.4≠0

This can never be true, lets move to the next term (x−22)=0x=

22 That's it! So your two consecutive numbers are

22

The greatest such intergers are;  Lesser = x = 6. Greater = x + 1 = 7

To find the  sum of consecutive integers, we will use

[tex]1 + 2 + 3 + ... + n = \dfrac{n(n+1)}{2}[/tex]

Here, Two consecutive integers represented as variables:

x, x + 1

Greater one: x + 1

Lesser one: x

Write as an equation

6(Greater) = 7(Lesser)

Substitute in known value;

6(x + 1) = 7(x)

Multiply

6x + 6 = 7x

Subtract 6x from both sides of the equation

6 = x

Lesser = x = 6

Greater = x + 1 = 6 + 1 = 7

0.74 + 0.19 = 0.93

0.1 = 1 tenth

hope this is right i-

The value of the sum of  0.74 and 0.19 is 0.93 and there are 9-tenths in the sum.

A summation, also known as a sum, is the outcome of adding two or more numbers or quantities. There are always an even number of terms in a summation. There could be only two terms, or there could be one hundred, a thousand, or a million.

Given:

Add 0.74 and 0.19,

Write the above phrase in mathematical form as shown below,

0.74 + 0.19

convert this into fractions as shown below,

74 / 100 + 19 / 100

Here the denominator is the same, so add the numerator,

(74 + 19) / 100

93 / 100

Answer:

-8265

Step-by-step explanation:

The product for the expression is -8265.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The product of (91 - 4) and (-91 - 4) can be found using the FOIL method of multiplying two binomials:

(91 - 4)(-91 - 4)

= 91(-91) + 91(-4) - 4(-91) - 4(-4)

= -8281 - 364 + 364 + 16

= -8281 + 16

= -8265

Therefore,

The product is -8265.

Answer:

Step-by-step explanation:

Answer:

205 is my answerrrrrrrrrrr

The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 147 days. Then the correct option is A.

The quadratic equation is given as ax² + bx + c = y. Then the degree of the equation will be 2.

The table shows the connection between the width in kilometers of an oil slick and the time in days. A capability can be utilized to show this relationship.

The equation at (2.4, 1) will be given as,

2.4 = a (1)² + b (1) + c

2.4 = a + b + c                 ...1

The equation at (9.4, 2) will be given as,

9.4= a (2)² + b (2) + c

9.4 = 4a + 2b + c                 ...2

The equation at (21.1, 3) will be given as,

21.1 = a (3)² + b (3) + c

21.1 = 9a + 3b + c                 ...

Solve equations 1, 2, and 3 with the calculator, then we have

a = 2.35, b = -0.05, c = 0.1

Then the equation is given as,

y = 2.35x² - 0.05x + 0.1

The best prediction of the time required for the oil spill to reach a diameter of 10 km will be

y = 2.35(10)² - 0.05(10) + 0.1

y = 235 - 0.5 + 0.1

y = 235.5

The value of y is nearer to the value of 233. Then the value of y will be 233 days.

The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 233 days. Then the correct option is D.

Answer:

y = 2x + 5 is an option

Answer: One unique solution.

Step-by-step explanation:

When we have a system of linear equations like:

y = a*x + b

y = c*x + d

We have 3 possibilities:

1) There is only one solution, this happens when in the graph, the lines intersect at only one point.

2) There is no solution, in this case, the lines never intersect, this would be the case of two parallel lines.

3) We have an infinite number of solutions, this happens when both lines intersect in an infinite number of points, and this can only happen when both lines are the same line.

In this case, we know that we have two lines and they intersect in only one point, (-1, 2)

Then we have only one solution, and the solution is (-1, 2)

Answer:

Step-by-step explanation:

===================================================

Work Shown:

Let's find out how many smaller cubes are needed to go along the 2 & 2/3 inch side length of the bigger box.

First convert to an improper fraction

2 & 2/3 = 2 + 2/3 = 6/3 + 2/3 = 8/3

Divide this over the side length of the small cube to get

8/3 divided by 1/3 = (8/3)*(3/1) = 24/3 = 8

So we need exactly 8 small cubes along the 2 & 2/3 inch side length.

Let A = 8 so we can use this later.

------------------

Repeat the same steps for the 3 & 1/3 inch side length

3 & 1/3 = 3 + 1/3 = 9/3 + 1/3 = 10/3

10/3 divided by 1/3 = (10/3)*(3/1) = 30/3 = 10

We need 10 cubes along the 3 & 1/3 inch side length.

Let B = 10.

------------------

Repeat for the 2 & 1/3 inch side length

2 & 1/3 = 2 + 1/3 = 6 + 1/3 = 7/3

7/3 divided by 1/3 = (7/3)*(3/1) = 21/3 = 7

We need 7 cubes along the 2 & 1/3 inch side length

Let C = 7

------------------

Multiply out the values of A,B,C to get

A*B*C = 8*10*7 = 560

This means we need 560 cubes that are each 1/3 of an inch along the the side to fill up a box that has dimensions of 2 & 2/3 inches by 3 & 1/3 inches by 2 & 1/3 inches.

Answer:

22*7= 154 miles

Step-by-step explanation:

Answer:

154 miles.

Step-by-step explanation:

7×22=154, just multiply

Answer:

1) Perimeter = 34 yards

If one of the width = 5 yards then the other width = 5 yards so 10 yards

34 yards - 10 yards = 24 yards divide by 2

Length = 12 yards

2) Perimeter = 24 m of fencing

Width = 7 m

2nd Width = 7 m

24 m - 14 m = 10 m divide by 2

Length = 5 m

3) The perimeter of a square is 12 feet

Note: All sides in a square is equal!

Side = 3 feet

4) The perimeter of a square pool is 30 feet

Note: All sides in a square is equal!

Side = 5 feet

Answer:

c + 3d = 14.75

2c + 5d = 26

A box of candy is $4.25 and a drink is $3.50

Step-by-step explanation:

Let c represent the cost of a box of candy and let d represent the cost of a drink

c + 3d = 14.75

2c + 5d = 26

Solve by elimination by multiplying the top equation by -2

-2c - 6d = -29.5

2c + 5d = 26

Add them together

-d = -3.5

d = 3.5

Plug in 3.5 as d into one of the equations to solve for c

c + 3d = 14.75

c + 3(3.5) = 14.75

c + 10.5 = 14.75

c = 4.25

So, a box of candy is $4.25 and a drink is $3.50

Total pie = x

Total pie left = 1/5x

Then, three friends came over and shared the leftover pie

How much of the pie did each friend eat?

Pie eaten by each of the three friends = leftover pie / 3 friends

= 1/5x ÷ 3

= 1/5x * 1/3

= 1/15x

Each of the three friends ate 1/15 of the pie
