Answer:
8.5 $
Step-by-step explanation:
Let Kiran 's salary is x $ per hour
hence cousin 's salary is x+ 30% of x per hour
or x+0.3x or 1.3x per hour
cousin 's earning 27(1.3x) = 35.1 x
kiran 's earning 23x
hence 35.1x +23x = 493.85
58.1x = 493.85
x = 493.85/ 58.1
x = 8.5 $
If you would like to solve the following proportion 15 / 21 = 5 / x, you can do this as follows:
15 / 21 = 5 / x /*x
15 / 21 * x = 5 /*21
15 * x = 5 * 21 /15
x = 5 * 21 / 15
x = 7
The correct result would be C. 7.
Answer:
2bricks
Step-by-step explanation:
volume of cuboid = length × breadth ×height
step 1 : calculate the first one
v= 15cm ×8cm× 5cm = 1200cm^3
step 2 calculate the 2nd one
v= 15cm ×10cm×8cm = 600cm^3
number of bricks
1200cm^3 × 1bricks/ 600cm^3 = 2 bricks
The probability that either die is even is 1/2 so the probability that both dies will be even on a single roll of both is:
(1/2)^2=1/4
