Answer:
the speed of sound is 12 miles per minute
Step-by-step explanation:
To know the speed we have to divide the distance by the time because the speed of sound is constant and we have to use a formula of uniform rectilinear motion
Uniform rectilinear motion: When an object travels at a constant speed with zero acceleration it is known as uniform rectilinear motion
The distance it gives us is 1 mile and the time it gives us is 1/12 minute
v = speed
v = 1mi / (1/12 m)
v = 12 mi/m
in the result as we can see we have a whole number (12)
the speed of sound is 12 miles per minute
Answer: ![\frac{5}{11}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B11%7D)
Step-by-step explanation:
Given
Kira order 2 pieces of tuna and 5 pieces of crab
While Marcy ordered 3 pieces of tuna and 6 pieces of crab
Total tuna ordered =2+3=5 pieces
Total crab ordered=5+6=11 pieces
The ratio of Tuna and crab is ![\frac{2+3}{5+6}=\frac{5}{11}](https://tex.z-dn.net/?f=%5Cfrac%7B2%2B3%7D%7B5%2B6%7D%3D%5Cfrac%7B5%7D%7B11%7D)
Answer:
Complementary and supplementary both describe an angle relationship. Complementary angles are angles that when added are equal to 90 degrees, (right angle). Supplementary angles are angles that when added together are equal to 180 degrees, (straight line). Two angles do not have to be adjacent to be complementary or supplementary.
5y - 10 = -25
5y = -25+10
5y=-15
y= -15/5
y=-3
