1/2, 2/3, 1/4, 5/6 = 6/12, 8/12, 3/12, 10/12 = 1/4, 1/2, 2/3, 5/6
First add 45 and 55 because sum means addition. 45+55=100 and teiple means multiplication and 3x100= 300 hope this helped :)
Answer:
As to sidea are equal therefore it is an isosceles triangle .
therefore
,80+x+x=180
80+2x=180
2x=100
x=50
Average speed is ALWAYS calculated as total distance / total time
<span>total distance is 100mi </span>
<span>total time is (50mi / 33) + (50mi / 80) </span>
<span>total time is = 1.52 + 0.625 = 2.145 </span>
<span>so average speed going to grandmothers house is 100mi / 2.145 hrs = 46.62 mph </span>
<span>on her return trip </span>
<span>x = V1 x t/2 + V2x t/2 </span>
<span>100 = 33t/2 + 80t/2 </span>
<span>100 = 113t/2 </span>
<span>t = 100x2/113 = 1.7699hrs </span>
<span>average speed = 100mi/1.7699hrs = 56.60mph</span>
*Hint: In order to find the area of a rectangle you multiply the length and width.
Because the scale is 1:240, you multiply the sides by 240.
2.5 turns into 600.
2 turns into 480.
A = lw
A = (600)(480)
A = 288,000
The area would be 288,000 square feet.
