Answer 1

Answer:

x = 9.83

Step-by-step explanation:

Taking 55 as the reference angle,

hypotenuse (h) = 12

perpendicular (p) = x

Sin 55 = p/h

Sin 55 = x / 12

x = Sin55 x 12

x = 9.83

Answers

Answer:

Total students = 460+320+165=945

Key stage 3 ... asafraction = 460 divide by 945

the number in a sample of 100 = 460 divide by 945 x 100= 48.67

which pair of these points defines a line with a slope 2/3? A. (2, 6) and (3, 0) B. (6, 2) and 3, 0) C. (6, 2) and (0, 0) D. (2, 6) and (0, 0)

Answers

Answer:

B. (6,2) and (3,0)

Step-by-step explanation:

To find the slope the equation is [tex]\frac{y_{2-y_{1} } }{x_{2} -x_{1} }[/tex] so for (6,2) and (3,0) the equation would look like this [tex]\frac{0-2}{3-6}[/tex] which simplies down to [tex]\frac{-2}{-3}[/tex] and a negative divided by a negative is a positive so you're slope is [tex]\frac{2}{3}[/tex] and it matches the question.

Explain (in words) what you would do to find the missing value in the equation. You do not find the missing number! Equation: ? + 59 5/8= 82 2/3 I will give Brainly whoever has the correct answer.

Answers

Answer:

The missing value = [tex]23\frac{1}{24}[/tex]

Step-by-step explanation:

Given - Equation: ? + 59 5/8= 82 2/3

To find - Explain (in words) what you would do to find the missing value in

              the equation. You do not find the missing number.

Proof -

Let the missing number = x

So, the equation becomes x + [tex]59\frac{5}{8}[/tex] = [tex]82\frac{2}{3}[/tex]

⇒x = [tex]82\frac{2}{3}[/tex] - [tex]59\frac{5}{8}[/tex]

     = [tex]\frac{248}{3} - \frac{477}{8}[/tex]

     = [tex]\frac{1984 - 1431}{24}[/tex]

     = [tex]\frac{553}{24}[/tex]

     = [tex]23\frac{1}{24}[/tex]

⇒x = [tex]23\frac{1}{24}[/tex]

∴ we get

The missing value = [tex]23\frac{1}{24}[/tex]

Explanation -

Here we have given the ? with addition of number that is equation to some number.

We just have to subtract the two numbers to find the missing value , as we do above.

An equilateral triangle with side length 9 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.

Answers

The answer is 35.1 cm².

Hope this helps; have a great day!

Question:-

Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.

_______________________________________________

Solution:-

In an equilateral triangle all sides are equal.

Let s = side length = 9 cm

Then, area of equilateral triangle is given as:

A = (√3/4)s²

Putting the value of s here,

A = (√3/4) * (9 cm)²

=> A = (√3/4) * 81 cm²

=> A = √3 * 20.25 cm²

We know that, √3 = 1.732

=> A = 1.732 * 20.25 cm²

=> A = 35.073 cm²

Rounding to one decimal place,

=> A = 35.1 cm²

Then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

2x × 12 = 15(x + 3) , that is

24x = 15x + 45 ( subtract 15x from both sides )

9x = 45 ( divide both sides by 9 )

x = 5
