Explanation:
Turn 18.9% into a decimal, which is 0.189
Then multiply 0.189 times 277, which is 52.4
When you divide 1722 by 6 you get 287 so it's not a repeating number so if you estimate 287 to 290 then you get 1740 so your answer is 287.
For 4 copies, the total cost for preparing and printing will be the same.
Step-by-step explanation:
Let,
p be the number of pages
Company A;
Charges of preparing = $6
Charges of per page print = $2.50
A(p)= 2.50p + 6 Eqn 1
Company B;
Charges of preparing = $4
Charges of per page print = $3
B(p)= 3p + 4 Eqn 2
For equaling the cost;
A(p) = B(p)

Dividing both sides by -0.50

For 4 copies, the total cost for preparing and printing will be the same.

As the triangles are similar, the ratio of their length and area will be the same
so as the ratio of the length is
16:12=4:3
the ratio of the area is also 4:3
we know the bigger triangle area is 105.
So 105 would be 4 units.
1 unit would be 26.25
and 3 units would be 78.75
rounded up to 79
