Every member of the family gives a gift to every other member of the family. There are ten members this year. If there are just 2 members exchanging gifts, how many gifts will be exchanged

Answers

Answer 1

Answer: The statement is contradictory, because it is said that every member of the family gives a gift to every other member of the family. And from 10 members, there are just 2 exchanging. Anyway, maybe they are only 2 members exchanging the gifts at that point in time.
So, each member will exchange 9 gifts (that is 10 members total minus herself), and 2 members are exchanging gifts at that point, so 18 gifts are being exchanged.

5. What is the area of the figure to the nearest square centimeter? It is composed of a symmetric hexagonand a semicircle 4 cm6 cm3 cm4 cmc 100 cmA 50 cm2D 129 cmB 86 cm

Answers

Area of the given figure is equal to $86\ cm^(2)$ ( nearest square centimeter).

What is area?

" Area is defined as the total space occupied by any two-dimensional object enclosed in it."

Formula used

Area of rectangle = length × width

Area of triangle $= (1)/(2) * base * height$

Area of semi-circle $= (1)/(2) * (\pi r^(2) )$

$r=$ radius of the circle

According to the question,

Given figure is composed of :

two congruent rectangles, four congruent triangles, one semi-circle

Given dimensions,

Length of a rectangle $= 6cm$

Width of a rectangle $= 4cm$

Height of a triangle $= 4cm$

Base of a triangle $= 3cm$

Radius of the semicircle $= (6)/(2)$

$=3cm$

Substitute the value in the formula to get the required area,

Area of a rectangle $= 6 * 4$

$= 24 cm^(2)$

Area of a triangle $= (1)/(2) * 3* 4$

$= 6 cm^(2)$

Area of a semicircle $= (1)/(2) * \pi * 3^(2)$

$=4.5 * 3.14\n\n= 14.13 cm^(2)$

Substitute the value to get the required area,

Area of the given composed figure $= 2* 24 + 4* 6 + 14.13$

$= 48 + 24 + 14.13\n\n= 86.13 \ cm^(2)$

≈ $86 cm^(2)$ (nearest square centimeter)

Hence, Option(B) is the correct answer.

Convert 0.00049 to scientific Notation

Answers

i think its 4.9 x 10-4

Answer:

It is 4.9 x 10-4

Step-by-step explanation:

So every time you do this type of scientific notation you need to count how many "0" there are and you need to check if they are in front of the number ( ex: 74.000 ) or if the are in the back ( ex: 0.0074 ) In this case since is in the back you would get the 10 and put it to the power of -4 since there is 4 zeros behind it. and then you just get the " 4 9 "( put a " . " between it ) and multiply it by $10^(-4)$ . ( You don't need to actually do the multiplication unless your teacher ask you to )

What percent is equivalent to .41

Answers

A percentage is always out of 100 and so if this is converted to a decimal, it is always out of 1.
The number has simply been divided by 100.
So to change a decimal to a percentage you simply multiply by 100.
So 0.41 x 100 =41%
