In an hour there are 60 minutes.
6:38 PM + 22minutes = 7 PM
From 7 PM to 7:23 PM there are 23 minutes
So, (23 + 22) minutes = 45 minutes.
Answer:
x = 4y + 28
Step-by-step explanation:
x/4 - 7 = y
+7 +7
x/4 = y + 7
× 4 × 4
x = 4y + 28
Answer:
A linear formula for S as a function of D is S=17D+1534
Step-by-step explanation:
We are supposed to find a linear formula for S as a function of D.
Equation of line : y = mx+c
We are given that At the surface, the speed of sound is 1534 meters per second.
c = 1534
We are given that for each increase in depth by 1 km, the speed increases by 17 m/s
So, Slope = m = 17
Substitute the values in equation
y=17x+1534
x denotes depth
y denotes speed
We are given that Use D for depth and S for the speed of sound
So, S=17D+1534
Hence a linear formula for S as a function of D is S=17D+1534
