Answer:
2.5x10^3= 2,500
5x10^6= 5,000,000
Step-by-step explanation:
Here is a great trick that I always keep in mind whenever you are squaring 10 you add that many zeros for example.
10^4= 10000 (there are 4 zeros).

The perimeter of a regular decagon is 267m.
State the length of one of its sides??
Answer: 26.7m
Step-by-step explanation:
Since a decagon has 10 sides, you'll have to divide 267m by 10.
267÷10= 26.7
One side of the decagon is 26.7m
The sixth-grade class is competing in the school field day. There are 32 girls and 56 boys who want to participate. Each team must have the same number of girls and boys. What is the greatest number of teams that can be formed? How many boys and how many girls will be on each team?
Answer:
8 teams each team will have 4 girls and 4 boys
Step-by-step explanation:
We use GCD to solve this
the GCD of 32 and 24 = 8
8 is the greatest number of teams.
each team must have equal number of boys and girls so divided by two
8/2 = 4
4 girls and 4 boys
I have attached how to do GCD.
If you need any clarification or more explanation pls do mention at the comment section
Hope this helps and if it does pls mark as brainliest answer thx

A 16-ounce bag of cereal costs about $2.88. What is the unit rade of the cereal?
Answer:
18 cents per ounce
Step-by-step explanation:
The first step is to identify the unit. In this case, you are told you have 16-ounces. Therefore, your unit is an ounce.
To find the price of one ounce, just divide your price of $2.88 by 16.
Unit rate = $2.88 / 16 = 0.18 or 18 cents per ounce.
Colin gets £x wages each week. After he pays his tax of £t, he
then pays his rent of £120. He shares what's left between
himself and his wife. How much do they each get?
Answer:
They will each get ;
(x-t)/2 - 60
Step-by-step explanation:
Here, we want to know the amount of money that Colin and his wife gets
we start by subtracting the necessary terms
Mathematically, that would be;
x-t-120
So what each of them get will be;
(x-t-120)/2
= (x-t)/2 - 60

For the current reaction, 2NO2 ↔ N2O4, we have:
Kc = [tex]\frac{[N_{2} O_{4}]}{[NO_{2}]^{2} }[/tex]
Concentration of NO2 = 11.95
Concebtration of N2O4 = 6.05
Based on the current concentrations of NO2 and N2O4, what is Kc?
[tex]\displaystyle K_c \approx 0.0424[/tex]

A bookstore charges a standard rate for paperback or hardback books. The cost of a paperback book is 4 dollars less than the cost of a hardback book. Recently, one day of sales totaled $1065.10. That day the bookstore sold 51 paperback books and 47 hardback books. Write a system representing this situation. Use the graph to estimate the solution of the system. What does the solution mean in this situation? How much does each type of book cost? Use substitution to verify your solution.
Answer: for one hard cover book it is about $17 and paperback is $13

help with this bounds question please
Answer: 6.68km/litre
Step-by-step explanation:
Distance(d) = 187km ( to 3 significant figures)
Petrol(p) = 28litres ( to 2 significant figures)
A number, x, rounded to 1 significant figure is 200
Write down the error interval for x
Calculating the lower and upper bound for both 'd' and 'p'
Upper bound 'd' = 187.5km
Lower bound 'd' = 186.5km
Upper bound 'p' = 28.5km
Lower bound 'p' = 27.5km
Therefore,
Petrol consumption (C) = d/p
Upper C = 187.5 / 28.5 = 6.57894
Lower C = 186.5 / 27.5 = 6.781818
Accuracy answer for C = (6.57894 + 6.781818) / 2 = 6.680379
= 6.68km/ litre ( to 3 significant figures)
To achieve a reasonable level of accuracy, the upper and lower bounds of P and D was used to calculate C, which was then averaged.
Using 3 significant figures ensure that we capture the C better, instead of early rounding.
