The answer is 15 as when we multiply 3 by 5 we get 15 and then we minus 4 to get 11 and finally add 4 resulting to 15
Answer=15
First, 1950m=1.95km, as 1000m=1km.
Then, 2.5-1.95=0.55km
0.55km = 550m
The side that has length 24 equals to 4y + 8
24 = 4y + 8
24 - 8 = 4y
16 = 4y
y= 16÷4
y = 4
The side that has length 31 equals to 7x - 4
7x - 4 = 31
7x = 31 + 4
7x = 35
x = 35 ÷ 7
x = 5
I would assume that the angle of f equals 50°... sincesince the triangles are similar that means that the angles are most likely equal to each other. since the big triangle you can do it 90 + 40 which equals 130 then 180, since that is the total degrees in a triangle, minus 130 equals 50 this means 50 ° is the angle of c. keep in mind angle c equals angle f.
Percent<span> simply means "per hundred" and the symbol used </span>to<span> express </span>percentage<span> is %. One </span>percent<span> (or 1%) is one hundredth of the total or whole and is therefore</span>calculated<span> by dividing the total or whole number by 100. </span>To calculate<span> the </span>percentage<span>difference between two numbers, the same basic calculations are used</span>
