The correct answer is option 1. Because when he is 5, he is in division one, that circle is filled in (that means it’s inclusive). When he turns seven, though, he moves up to division two. That means that it’s inclusive when he turns seven, but not when he turns five. So, it’s an inclusive closed circle on the left, and an exclusive open circle on the right. Lmk if u need more clarity!
Answer:
Age of Alice = 25, Age of Jane = 20.
Step-by-step explanation:
Let age of Alice = x
Then age of Jane is 80% of the age of Alice
=> Age of Jane = 80% of x = 80/100 * x = 0.8x
Adding the two ages gives 45.
The two ages are x and 0.8x.
The sum of the two ages is x+ 0.8 x = (1+0.8)x = 1.8x.
=> 1.8 x = 45
Dividing both sides by 1.8, x = 45/1.8
=> x= 25
But x represents the age of Alice.
So age of Alice is 25.
Age of Jane = 0.8* 25 = 20
Verification: Adding the two ages gives 45.
Answer:
<em>Width = 6k²</em>
<em>Length = 5k+1</em>
Step-by-step explanation:
Given the area of a rectangle expressed as
A = 30k³ + 6k²
Get the greatest common factor
30k³ = (2 * 3 * k²) * k * 5
6k² = (2 * 3 * k²)
The common factor is the value in bracket i.e 2 * 3 * k² = 6k²
<em>Width of the rectangle = 6k²</em>
<em></em>
Get the length
A = LW
L = A/W
L = 30k³ + 6k²/6k²
L = 6k²(5k+1)/6k²
L = 5k + 1
<em>Hence the length L = 5k+1</em>
Answer:
net income = (cost of goods sold) - (net sales) - (operating expenses)
Step-by-step explanation:
because income is based on sales, thus the cost of how much you got minus all the expenses must be the net income.
