Answer:
a; 3.45 * 10^3
b) 2.34 * 10^18
c) 80%
Step-by-step explanation:
a) 3450 in standard form
To write in standard form, we have to place a decimal at the back of the first non-zero number
we have this as ;
3.450
The count of numbers after the decimal point is 3
This will be the power to which 10 will be raised
We have this as;
3.45 * 10^3
b) 234 * 10^16
Let us write 234 in standard form
That will be;
234 = 2.34 * 10^2
So we have ;
2.34 * 10^2 * 10^16
Using the law of indices, we have;
2.34 * 10^(2 + 16) = 2.34 * 10^18
c) From the question, Kuwait is 4/5 of Hong kong’s population
Let Honk Kong’s population be x
4/5 * x = 2.4 million
4x = 5 * 2.4 million
x = 5 * 2.4/4
x = 5 * 0.6
x = 3 million
so writing the population of Kuwait as a percentage of that of Hong kong, we have
2.4/3 * 100%
= 0.8 * 100% = 80%

Answer:
He would collect 28 cans
Step-by-step explanation:
Ethan = 1/3
84 * 1/3 = 28
Answer:
28 cans were collected by Ethan
Step-by-step explanation:
It says that the total amount of cans collected was 84 cans. Of the 84 total cans, Ethan collected 1/3 of them. To find the number of cans Ethan collected, you would multiply 84 • 1/3. (You could also divide 84 by 3 in this case)
84 • 1/3 = 28

A triangle has side lengths 25 in 33 in and 41 in is a front of a cute obtuse or right
Answer
The triangle is an obtuse.
Step-by-step explanation:
25 + 33 + 41 = 99
90 Is a right angel.
But the triangle is 99 which makes it an obtuse.
The sum of squares of the two smaller sides is greater, the triangle is acute.
Acute triangle :To determine whether the triangle is acute, right, or obtuse, add the squares of the two smaller sides, and compare the sum to the square of the largest side.
Given sides of triangle are, [tex]25,33[/tex] and [tex]41[/tex].
Squares of the two smaller sides is,
[tex]=25^{2} +33^{2} \\\\=625+1089=1714[/tex]
Square of third side [tex]=41^{2} =1681[/tex]
Since the sum of squares of the two smaller sides is greater, the triangle is acute.

Since 2005, the amount of money spent at restaurants in a certain country has increased at a rate of 5% each year. In 2005, about $290 billion was spent at restaurants. If the trend continues, about how much will be spent at restaurants in 2020? PLEASE HELP ME
Answer:
About $603
Step-by-step explanation:
Given data
The time interval 2005-2020= 15 years
The principal amount spent= $290 billion
The rate= 5%
Let us apply the compound interest formula
A=P(1+r)^t
substitute
A=290(1+0.05)^15
A= 290(1.05)^15
A= 290*2.0789
A= $602.881
Hence about $603 will be spent in 2020

add 21 both sides
[tex]87\geq 7x[/tex]
divide both sides by 7

Determine the length of the longest piece of timber which could be stored in a rectangular shed 6cm by 5cm by 2m high
Answer:
6 90u7 jhi
Step-by-step explanation:
Answer:
200.2
Step-by-step explanation:
I would hate to own such a shed. It's not very big.
2 meters = 2 * 100 cm = 200 cm
The diagonal of the floor is the diagonal of 6cm by 5cm. Using a^2 + b^2 = c^2
5^2 + 6^2 = 25 + 36 = 61
The square root of 61 is 7.81 cm
Now the diagonal of the floor diagonal and the height
a^2 + h^2 = board^2
61 + 200^2 = board^2
61 + 40000 = board^2
40061 = board^2
sqrt(board^2) = sqrt(40061)
board = 200.2cm long.
