solve the following pair of equations by elimination method: x+y=4, 2x+y=3​

Answers

Answer 1

Answer:

x = 1

y = 5

Step-by-step explanation:

x + y = 4 __ (1)

2x + y = 3 __ (2)

equation (1) x 2, (2) x 1

2x + 2y = 8

2x + y = 3

0  + y = 5

y= 5 (ANS)

x + y = 4

x + 5 = 4

x = 5 - 4

x = 1 (ANS)

Number of Handshakes If eight people greet each other at a meeting by shaking hands with one another, how many handshakes take place?

Answers

The number of handshake that took place is 28.

In any situation where order of an outcome does not matter, mathematical combination (C) are use calculate the total outcomes of an event.

8 people are to shake each other once. The concept to be use to derive the number of hands that took place is Combination.

The formulae of Combination for this Scenario is n(n-1)/2n(n−1)/2 .

The number of people (n) is 8.

\begin{gathered}Total handshake = n(n-1)/2\\Total handshake = 8 * (8-1)/2\\Total handshake = 8 * 7/2\\Total handshake = 56/2\\Total handshake = 28\end{gathered}Totalhandshake=n(n−1)/2Totalhandshake=8∗(8−1)/2Totalhandshake=8∗7/2Totalhandshake=56/2Totalhandshake=28

In conclusion, the number of handshake that took place is 28.

Area = 12 + 6.25π ft², Perimeter = 6 + 5π ft

Step-by-step explanation:

Area:

So I would break this shape into a triangle and a circle (the two semi-circles make a full circle).

Formula for Area of a Triangle: base · height ÷ 2

6 · 4 ÷ 2 = 24 ÷ 2 = 12

Formula for area of a circle: π · radius²

π · (5/2)² = 6.25π

Area of entire shape: Triangle + Circle

Area = 12 + 6.25π ft²

Perimeter:

So the perimeter is made up of the base of the triangle plus the circumference of the circle.

Base of Triangle: 6

Formula for circumference: 2rπ

5 · π = 5π

Perimeter = 12 + 5π ft

if 1/5 of 100 oranges is given to Ade and 1/4 of the remaining orange is given to Hardy what fraction of the orange is left​

Answers

Answer:

3/5

Step-by-step explanation:

5/5 - 1/5 = 4/5

4/5 × 4/4 = 16/20

16/20 - 4/20 (1/4) = 12/20

12/20=3/5

I think this is right

The remaining fraction of oranges left is A = 3/5 of the total oranges

What is a Fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the remaining fraction of oranges be A

And , if 1/5 of 100 oranges is given to Ade, then Ade gets:

1/5 * 100 = 20 oranges

The remaining oranges are:

100 - 20 = 80 oranges

Now , if 1/4 of the remaining oranges is given to Hardy, then Hardy gets:

1/4 * 80 = 20 oranges

So the total number of oranges given away is:

20 (Ade) + 20 (Hardy) = 40 oranges

The fraction of the oranges that is left is:

(100 - 40) / 100 = 60 / 100 = 3/5

Hence , 3/5 of the oranges are left

The length of a rectangle is 10 ft less than three times the width, and the area of the rectangle is 77ft^2 . Find the dimensions of the rectangle.

Answers

Answer:

The dimensions of rectangle are 11 feet and 7 feet.

Step-by-step explanation:

Given, The length of a rectangle is 10 ft less than three times the width, and the area of the rectangle is 77 ft²

Let's assume width of rectangle be x feet and Length of rectangle be 3x - 10. Using the formula of area of the rectangle we'll find the dimensions of the Rectangle.

[tex] \\ \dashrightarrow{ \red{\underline{\underline{\sf{Area (rectangle) = Length \times width }}}}} \\ \\ [/tex]

Substituting the required values:

[tex]\dashrightarrow \: \: (3x-10)(x) = 77 \\ [/tex]

[tex]\dashrightarrow \: \: 3x^2 - 10x = 77 \\ [/tex]

[tex]\dashrightarrow \: \: 3x^2 -10x -77 = 0 \\ [/tex]

[tex]\dashrightarrow \: \:3x^2 + 11x -21x -77 = 0 \\ [/tex]

[tex]\dashrightarrow \: \: x(3x+11)-7(3x+11) = 0 \\ [/tex]

[tex]\dashrightarrow \: \: (x-7)(3x+11) = 0 \\ [/tex]

[tex]\dashrightarrow \: \: { \red{\underline{\underline { x = 7 \: or \: \dfrac{-11}{3}}}} } \\ \\ [/tex]

Hence,

Width of rectangle = x = 7 feetLength of rectangle = 3x -10 = 3(7) - 10 = 11 feet

[tex] \therefore[/tex] The required dimensions of rectangle are 11 feet and 7 feet.

The dimensions of the given rectangle with an area of 77 ft^2 and given dimensions are; Length = 11 ft and Width = 7 ft

How to find the Area of a rectangle?

Formula for area of a rectangle is;

A = Length * Width

We are given;

Length; L = 3W - 10

Thus;

Area; A = W(3W - 10)

Thus;

W(3W - 10) = 77

3W² - 10W - 77 = 0

Using online quadratic equation calculator, we have;

W = 7

Thus;

L = (3*7) - 10

L = 11 ft
