1. you have to figure out what 3/4 of Ella's time is.
1 \frac{3}{5}  =  \frac{8}{5}
(You find that out by multiplying 5x1. Then add 3.)
2. Convert the fractions into decimals. (This will help make it easier when dividing.)
\frac{8}{5}  = 8 \div 5 = 1.6
\frac{3}{4}  = 3 \div 4 = .75
3. Next you are going to divide 1.6 by .75
1.6 \div .75 = 2.13
4. Now multiple 2.13 by 5.
2.13 \times 5 = 10.65
Answer is 10

Divide rs 350 in ratio 2:5​
mihalych1998 [28]

Answer:

100 : 250

Step-by-step explanation:

Sum the parts of the ratio, 2 + 5 = 7 parts

Divide the quantity by 7 to find the value of one part of the ratio.

350 ÷ 7 = 50 ← value of 1 part of the ratio, thus

2 parts = 2 × 50 = 100

5 parts = 5 × 50 = 250

350 = 100 : 250 in the ratio 2 : 5

lesya [120]
Resultant Vector: 554 N in the angle 80 degrees with the horizontal.


First, we must put each given in Polar form:
1. 500 N in the angle of 35 degrees with the horizontal
2. 400 N in the angle of 140 degrees with the horizontal in the same direction of the first guy wire (counterclockwise direction)

Then, add up the two polar forms, and it would give 553.59 in the angle of 79.26 with horizontal- counterclockwise direction. As estimated, 554 N in the direction of 80 degrees North of East.
