Answer: 49
Step-by-step explanation:
There would be 49 dots because each number is a square number. You skip 1 so every square‘s number is one less than the square root of the number of dots.

Answer:
answer
Step-by-step explanation:
PR=QR so 3x-0.6=x+2.4
2x=3
x=1.5
PR=QR=3.9
PQ is cut put but you just have to add 1.5 to the value added with the plus
Answer:
On 5 liters of petroleum he can go 100km.
He needs 37.5 liters of petroleum to go 750km.
Step-by-step explanation:
He goes 20km on 1 liter. Now we must find how far he can go on 5 liters.
1 * 5 = 5
20 * 5 = 100
The reason we multiplied was because we had to multiply 1 by 5 to get the number of liters of petroleum and what you to one side you must do to the other.
To find how many liters are needed to go 750km you must divide:
750/20 = 37.5
He needs 37.5 liters of petroleum to travel 750km.
Hope this helps! :)
Answer:
<h2>
300 + 69x</h2>
Step-by-step explanation:
Given initial population of animals = 300 animals
If the population increases by 23% annualy, yearly increment will be expressed as:
Yearly increment = 23% of 300
Yearly increment = 0.23*300
Yearly increment for = 69
Let the total number of years of be x
Increment after x years = 69x
Increase in population of animals after x years with an annual rate of 23% = Initial population + Increment after x years
= 300 + 69x
<em>Hence, the equation represents a population of 300 animals at the increase and an annual rate of 23% is expressed as 300 + 69x</em>
15*15=225. There's only one square root of 225... there's only one square root of any number ...
