Lattice multiplication, also known as gelusia multiplication, sieve multiplication, shabakh, Venetian squares, or the Chinese lattice, is a method of multiplication that uses a lattice to multiply two multi-digit numbers.
Answer:
you need to divide 1.2925 by 0.7925=1.630914826498423 or a abrebiation
Step-by-step explanation:
Answer:
You simply take the values away from 180°.
a) 180-85-65 = 30°
b) 180-37-63=80°
c) 180-52-78=50°
d) 180-102-58=20°
e) 180-100-60=20°
f) 180-105-25=50°
g) 180-127-23=30°
Answer:
Speed of sound is 340 meter per second.
Step-by-step explanation:
Let the speed of sound = x meter per second.
It is given that,
The new mode of travel has the speed 170 meter per second, which is 50% less than the speed of sound.
So, we get,
x - 50%x = 170
i.e. x - 0.5x = 170
i.e. 0.5x = 170
i.e. x = 340 meter per second
Hence, the speed of sound is 340 meter per second.
Answer is c. $62.99
Step by step
89.99 x 70% = x
89.99 x .70 = 62.99
Hint: If the dress was 30% off, it’s cost is 70%
You can also do this in two steps
89.99 x 30% = discount of $27.
Then
89.99 - $27 = $62.99
