The given figure is divided into two rectangles. We will find the area of both reactangles and then add their area to find the total area of the composite figure...

<h3>Area of reactangle 1⤵️</h3>

Length = 4cm
Breadth = 6cm

$\sf \: area = length \times width$

$\sf \: area = 4 \times 6$

$\tt \: area = 24cm ^{2}$

<h3>Area of rectangle 2⤵️</h3>

Length = 5cm
Breadth = 6+4= 10cm

*Note:- The measure of dotted line will be equal to the side opposite to it since it is a rectangle...

$\sf \: area = length \times breadth$

$\sf \: area = 5 \times 10$

$\tt \: area = 50cm ^{2}$

<em>Thus, The area of figure A is 24cm² and area of Figure B is 50cm²....</em>

And the total area of composite figure will be

24cm²+50cm²
74cm² is the total area...

Answer:

The second option is correct.

Step-by-step explanation:

$Solution,\\Breadth(b)=5cm\\Length (l)=4cm+6cm=10cm\\Now ,\\Area=l*b=5cm*10cm=50cm^{2}$

Jason deposited $18 000 in a bank that offers an interest rate of 5% per annum compounded

8_murik_8 [283]

Answer:

$1995.97.

Step-by-step explanation:

Amount in bank after 20 days =

18000(1 + 0.05/365)^20

= $18049.38

So H = 18049.38 - 16093.41

= $1995.97.

A survey asked people of different ages whether they get their news by reading the paper. What is the probability that a person

Bingel [31]

C. 60%

The probability that a person surveyed is 40 or older and gets the news by reading the paper is 60%.

Step-by-step explanation:

In our case, we have to find the probability of a person getting their news by reading the paper. But we are given with a condition that the person must be 40 or older.

The survey is conducted among 80 people.

Number of people aged 40 or older = 40

No of people aged 40 or older and read paper = 24

Probability formula is the ratio of number of favorable outcomes to the total number of possible outcomes.

Probability of a person aged 40 or older reads a paper =

(No. of People aged 40 or older and read paper)/(No. of people aged 40 or older)

= 24/40

= 0.6

= 60%

Find an equation of the line satisfying the given conditions Through (6,4); perpendicular to 3X + 5Y =38

Katyanochek1 [597]

To answer this, we will need to know:

• The slope of the equation we are trying to get
• The point it passes through using the

First, we will need to find the slope of this equation. To find this, we must simplify the equation $3x+5y=38$ into $y=mx+b$ form. Lets do it!

$3x+5y=38$
= $5y = -3x+38$ (Subtract 3x from both sides)
= $y= -\frac{3}{5}x+ \frac{38}{5}$ (Divide both sides by 5)

The slope of a line perpendicular would have to multiply with the equation we just changed to equal -1. In other words, it would have to equal the negative reciprocal.

The negative reciprocal of the line given is $\frac{5}{3}$ .

Now that we know the slope, we have to find out the rest of the equation using the slope formula, which is:

$\frac{y-y _{1} }{x- x_{1} }=m$

Substituting values, we find that:

$\frac{y-4}{x-6}= \frac{5}{3}$

By simplifying this equation to slope-intercept form (By cross-multiplying then simplifying), we then get that:

$y= \frac{5}{3}x-6$ , which is our final answer.

Thank you, and I wish you luck.
