Answer:

Step-by-step explanation:

in order to do this we have to look at the ratio and so in order to get from 10 to 60 on the denominator we multiply by 6 so what you do to the bottom you must also do to the top so we multiply the 5 by 6 and we get our answer of 30

ΔABC has three sides with these lengths: AB = 9, BC = 40, and CA = 41. What is the value of cos C?

kotykmax [81]

Answer:

$cos(C) =\frac{40}{41}\\\\cos(C)=0.976$

Step-by-step explanation:

To find the $cos (C)$ we must use the cosine theorem.

The cosine theorem says that:

$c^2 = a^2 +b^2 -2abcos(C)$

In this case:

$c=AB = 9$

$b=CA = 41$

$a=BC = 40$

$9^2 = 40^2 +41^2 -2(40)*(41)cos(C)$

$9^2- 40^2- 41^2 =-2(40)*(41)cos(C)$

$cos(C) = -\frac{9^2- 40^2- 41^2}{2(40)*(41)}$

$cos(C) =\frac{40}{41}\\\\cos(C)=0.976$

There are 36 graduated cylinders to put away on a shelf

Sergio039 [100]

Answer:

There are three possible arrangements of the graduated cylinders on the shelf. 

1. 4 rows of 9 graduated cylinders 

2. 3 rows of 12 graduated cylinders. 

3. 2 rows of 18 graduated cylinders.

Step-by-step explanation:

Number of graduated cylinders to put away on the shelf = 36

Maximum number of graduated cylinders that can fit across = 20

Maximum number of graduated cylinders that can fit deep = 4

The teacher wants each row to have the same number of cylinders.

First option of arrangement:

4 rows of 9 graduated cylinders

It fits across (less or equal to 20) and deep (less or equal to 4)

Total of graduated cylinders used = 36 ( 4 x 9)

Second option of arrangement:

3 rows of 12 graduated cylinders

It fits across (less or equal to 20) and deep (less or equal to 4)

Total of graduated cylinders used = 36 ( 3 x 12)

Third option of arrangement:

2 rows of 18 graduated cylinders

It fits across (less or equal to 20) and deep (less or equal to 4)

Total of graduated cylinders used = 36 ( 2 x 18)

No other arrangement is possible, because a only row of 36 graduated cylinders doesn't fit across or 6 rows of 6 don't fit deep.
