24. Find the perimeter and area of the triangle below.
базь
2a3b
4ab

Answers

Answer:

Answer to the first part:  8a³b + 4ab

Step-by-step explanation:

Perimeter = distance around the three sides

P = 6a³b + 2a³b + 4ab

P = (6a³b + 2a³b) + 4ab           add like terms

P = 8a³b +4ab                          Simply

The value of the perimeter and area of the triangle are,

20.52 cm²  and 28.68 cm

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Now, By Using Pythagoras theorem to find the base of the triangle as;

a² = 6² - 3²

a ² =  27

a = √27

And, b² = 9² - 3²

b² =  72

b = √72

Hence, Base = √27 + √72

= 13.68

So, We get;

Area = 0.5 x 13.68 x 3

Area = 20.52 cm²  

And, The value of perimeter is,

Perimeter = 9 + 6 + 13.68

= 28.68

Thus, The value of the perimeter and area of the triangle are,

20.52 cm²  and 28.68 cm

How do you solve 4 over 5 times 3.75

Answers

Answer:

3

Step-by-step explanation:

First of all simplify 4/5 to .8

Then Multiply:    .8*3.75=3

9514 1404 393

Answer:

  4/5×3.75 = 3

Step-by-step explanation:

There are many solution strategies available. Among them are ...

use a calculator to find 4/5×3.75 = 3convert the numbers to decimal and multiply by hand 0.8×3.75 = 3.000compute 2(2×3.75)/5 = 2(7.5)/5 = 15/5 = 3 in your headconvert 3.75 to an improper fraction and multiply (4/5)(15/4)=15/5=3

__

Additional comment

The mental arithmetic involved in adding a number to itself (doubling a number) is usually pretty easy. This means it is relatively easy to multiply by powers of 2, such as 4, 8, or 16. The second strategy listed above can be done in your head as ...

  8/10×3.75 = 2×(2×(2×3.75))/10 = 2×(2×7.5)/10 = 2×15/10 = 30/10 = 3

The same product can be found as ...

  8/10×3.75 = 8×(3.75/10) = 8×0.375 = 8×(3/8) = 3

In all cases, it is helpful to know your times tables, decimal equivalents of common fractions, and a few shortcut strategies for mental arithmetic. These are not difficult, but they do require you put some effort into memorizing them.

What methods do you know that can be used to solve a quadratic equation?

Answer: If the quadratic equation has real, rational solutions, the quickest way to solve it is often to factorise into the form (px + q)(mx + n), where m, n, p and q are integers. This is especially true where the coefficient of x2 is 1.

Answer:

( i ) ∠AOB = 72

( ii ) ∠BOC = 67

( iii ) ∠COD = 134

( iv ) ∠AOD = 87

Step-by-step explanation:

Sum of angles in a circle is 360,

a + b + c + x = 360

72 + 67 + 134 + x = 360

273 + x = 360

x = 360 - 273

x = 87

∠AOB = a = 72

∠BOC = b = 67

∠COD = c = 134

∠AOD = x = 87

Step-by-step explanation:

From the diagram,

AOB = a= 72

BOC = b = 67

COD= c = 134

&

AOD+AOB + BOC+ COD= 360 [Angle ofcomplete turn]

or,AOD + 72+67+134= 360

or,AOD +273=360

or AOD= 360-273=87degree

Answers

The solution to the algebraic equation, −0.4x − 3.1 = 5.9, is: x = -22.5

Given the algebraic equation, −0.4x−3.1 = 5.9, to solve for x, follow the steps below:

−0.4x − 3.1 = 5.9

Add 3.1 to both sides

−0.4x − 3.1 + 3.1 = 5.9 + 3.1

-0.4x = 9

Divide both sides by -0.4

-0.4x/-0.4 = 9/-0.4

x = -22.5

Therefore, the solution to the algebraic equation, −0.4x − 3.1 = 5.9, is: x = -22.5
