Step-by-step explanation:
Answer: The mid-point of AC easy to calculate.
It is at ((5+3)/2,(5−1)/2)=(4,2) .
What you really asked was the coordinates of the point 3/4 of the way from A to C, and the calculation is very similar. I think of it as giving a “weighting” to the nearest point. So in this case we give a weighting of 3 to point C and 1 to point A.
Then =((5+3∗3)/4,(5−1∗3)/4)
So =(3½,½) .
CHECK:
Distance
2=(5−3½)2+(5−½)2
=(3/2)2+(9/2)2=9/4+81/4
=90/4
So the distance =310‾‾‾√/2
And the distance
2=(3½−3)2+(½+1)2
=1/4+9/4=10/4
And so the distance BC is 10‾‾‾√/2 which is indeed one third of the distance AB.
Step-by-step explanation:
Since it is 2 shirts
15 times 2 = 30
30% of off 30 dollars is 21 dollars
7% tax increase will come to 22.47
The total cost should be $22.47

Answer:
7
Step-by-step explanation:
the area of a triangle is base*height/2. so, if the area is 14 mm^2, we have to figure out how much the area would be without dividing by 2. the opposite of division is multiplication, so 14*2=28. now that we know how much the area would be if we didnt divide by 2, we have to figure out the base. the equation is:4x=28. we divide 4 on each side and we get x=7.
