A) Divide the total height by the average height:
26.4 / 1.2 = 22 total boys.
B) Divide total feet by total time:
440 feet / 20 seconds = 22 feet per second.\
Because the submarine is diving the rate would become negative 22 feet per second.
Answer:
-3
Step-by-step explanation:
The slope formula is y2-y1/x2-x1, so replace the variables with the given values.
-5-5/1-x= -5/2, now multiply both sides by "1-x"
-5-5= -5/2(1-x) or -10=-5/2+5/2x, now add 5/2 to both sides
-20/2+5/2=5/2x, now simplify the equation
-15/2=5/2x, multiply both sides by 2/5
-30/10=x or x is -3
Answer:
h = 21.5cm.
Step-by-step explanation:
<em>Step one:</em> Simplify the volume.
220.16 x (pi) = 691.65cm^3.
<em>Step two:</em> Isolate h.
Cylinder volume equation: V = (pi)(r^2)(h), where r is the radius and h is the height.
Divide out the pi and r^2 on both sides to isolate h and move the equation to V/(pi)(r^2) = h.
<em>Step three:</em> Solve for h.
691.65/(pi)(3.2^2) = 21.5cm rounded to the nearest tenths place.
To illustrate this, please check the diagram below.
Answer: 21 degrees
Step-by-step explanation:
In the evening, the temperature is 28 degrees and by midnight it has dropped 31 degrees lower, the temperature by midnight will be:
= 28° - 31°
= -3°
Between midnight and 4 am it goes down 6 more degrees. The temperature by 4am will be:
= -3° - 6°
= -9°
Then, by 9 am, the temperature goes up 30 degrees, the temperature at 9 am will then be:
= -9° + 30°
= 21°
