Hello! A can is the shape of a cylinder. The formula for the volume of a cylinder is this: pi * r^2 * h. The radius is 1/2 of the diameter. Half of 13.6 is 6.8. 6.8^2 is 46.24. 46.24 * 15 is 693.6. Now, we can multiply by pi as 3.14. 693.6 * 3.14 is 2,177.904 or 2,177.9 when rounded to the nearest tenth. The volume of the cam is approximately 2,177.9 cubed centimeters.

Divide the known y's by the known x's:

1/3 = 1/3

2/6 = 1/3

4/12 =1/3

The Y values are 1/3 of the x values.

Multiply the know x value by 1/3 to get y:

y = 9 x 1/3 = 3

y = 3

Hank's car travels 600 feet in 20 seconds. Andy's motorcycle travels 300 feet in 12 seconds. Which is faster, the car or the mot

Alexus [3.1K]

Answer:

the car travels faster

Step-by-step explanation:

Since the motorcycle has traveled 300 feet, and the car has traveled 600 feet, we will divide 600 by 2

600 divided by 2 = 300

Hank would have traveled 300 feet in 10 seconds

Andy traveled 300 feet at 12 seconds

Therefore Hanks car travels faster

netineya [11]

Answer:

Therefore

$det(A)*det(A^{-1}) = 1$ and $det(A^{-1}) = 1/det(A)$

Step-by-step explanation:

Remember that if

$I$ = Identity Matrix

then $det(I)=1$ .

Also remember that for any invertible matrix

$A*A^{-1} = I =$ Identity Matrix.

Therefore

$det(A*A^{-1}) = det(A)*det(A^{-1}) = det(I) = 1$

Therefore

$det(A)*det(A^{-1}) = 1$ and $det(A^{-1}) = 1/det(A)$

The mean temperature for the first 4 days in January was 8°C. The mean temperature for the first 5 days in January was 7°C. What

ahrayia [7]

Answer : The 5th day = 3 Celsius

Explanation:
the average of the first 4 day is 8
Which mean the combine temp on the first 4 day is 8 x 4 = 32

Now on the first 5 day the average temp is 7

Then the combine temp on the first 5 day is 7 x 5 = 35

Find the 5th day

4 days combine temp + 5th day = the combine temp of 5 days

32 + 5th day = 35
5th day = 35-32
5th day temp = 3C
