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

_______________________________________________

The answer is 35.1 cm².

Hope this helps; have a great day!

Answer:

6.28 inch =6inch approx is your answer

Step-by-step explanation:

60minute=360°

{5:45-5:35=10)

10minute =360/60×10=60°

radius (r)=6inch

now

length of arc =60/360 ×2πr

=60/360×2×3.14×6=6.28 inch

Answer:

b^5

Step-by-step explanation:

The expression `b+b+b+b+b` is equivalent to 5b, which is a product of a coefficient and a variable.

It is defined as the combination of constants and variables with mathematical operators.

We have:

= b+b+b+b+b

Here, b is the variable after adding b five times we get:

= 5b

5 is the coefficient and b is a variable.

Thus, the expression `b+b+b+b+b` is equivalent to 5b, which is a product of a coefficient and a variable.

Answer:

Jared and Nicole are correct.

Step-by-step explanation:

You can solve for either variable and use the equivalent expression to create a one-variable equation. They manipulated the equation right. They can either write the equation as y as a function of x then substitute it to the y in the other equation and solve for x. For both solutions, they'll still get the same answers.

x+(x-34) =90

2x-34=90

2x=56

x=28 (small angle)

28+34=62 (big angle)

Step-by-step explanation:

Answer:

There will be no real solution. A further explanation is given below.

Step-by-step explanation:

The given equation is:

⇒ [tex]7x-12<7(x-1)[/tex]

On solving bracket, we get

⇒ [tex]7x-12<7x-7[/tex]

On putting numbers on the right side and x's on the left side of the equation, we get

⇒ [tex]7x-7x<-7+12[/tex]

⇒ [tex]0<5[/tex]

Thus the above is the appropriate solution.

Answer:

Step-by-step explanation:

-x-3=y, therefore x = -y-3

-3x - 8y = 4

Find the value of y

Substitute the x in -3x - 8y = 4 with -y-3

We get

-3·(-y-3) - 8y = 4

3y + 9 - 8y = 4
