X=20. Hoped this helped! If you need an explanation ask away....
< 3 + < 4 = 180 degrees ( adjacent angles)
<3 + 52 + 25 = 180 degrees (angles in a triangles)
So if we subtract these 2 equations:-
<4 - (52 + 25) = 0
< 4 = 52 + 25
92.5 percent of the order was missing because 740 of 800 is 92.5 percent good luck
Answer:
4.806 g ≤ n ≤ 5.194 where n is the mass of a nickle.
Step-by-step explanation:
The problem tells us the weight can vary by .194 g, this means it can be up to .194 lighter and 194 heavier. Well what value is .194 lighter and .194 heavier? 4.806 and 5.194 respectively. So that means a nickle can be anywhere in that range, which tells us the inequality.
You can find this answer multiple ways.
One way is to represent it as an equation and solve for x, The total number of vehicles.
0.4x = 98
x = 245 vehicles
Or write a proportion using the fraction for 40%.
2/5 = 98/x
5 x 49 = 245
There are 245 vehicles in the garage.
