1. Find the greatest number that will divide 43, 91 and 183 so as to leave the same remainder in each case
A. 4
B. 7
C. 9
D. 13
Ans:A
Explanation: Required number = H.C.F. of (91 – 43), (183 – 91) and (183 – 43)= H.C.F. of 48, 92 and 140 = 4.
1. The H.C.F... |
The distance d that an object will travel is equal to its rate r times its time t.
d = r t
Rate is sometimes called speed or velocity. Rates are given as ratios, such as “miles per hour” or mph and “kilometers per hour” or km/h.
The distance covered in 1 hour at 20 miles per hour is the same as the distance covered ... |

h = 1886.8 m
Step-by-step explanation:
Step 1: Get one more angle in the left triangle.
Notice that there is an angle suplementary to angle β.
angle = 180° - β = 180°- 49° = 131°
Step 2: Get hypotenuse.
You can either calculate hypotenuse of the big right triangle or small right... |
# What Is the Difference Between Direct and Inverse Proportion?
The difference between direct and an inverse proportion is simple to explain by using equations. While the equation for direct proportions is y = kx, the equation for inverse proportions is y = k/x. In these equations, k is a constant, and x and y are the... |
