Find the value of cos C rounded to the nearest hundredth, if necessary
Sindrei [870]

\bold{\frac{5}{13} or 0.38}

Answer:

Solution given:

here

by using Pythagoras law

hypotenuse =

\displaystyle\sqrt{adjacent ²+opposite ²}\\=\sqrt{15²+36²}=39

Cos C=\frac{adjacent} {hypotenuse}=\frac{15}{39}=\frac{5}{13} or{0.38}

6x − y + z = −3<br> 4x − 3z = −13<br> 2y + 5z = 15<br> Find the solutions?
Alla [95]

Answer:

The solution of the equation are x = - 1 , y = 0 and z = 3

Step-by-step explanation:

Given three linear equation as :

6 x - y + z = - 3        ......A

4 x - 3 z = - 13           ......B

2 y + 5 z = 15            ......C

Solving eq A and C

I.e 2× (6 x - y + z ) = -3 ×2

or, 12 x - 2 y + 2 z = - 6

So, ( 12 x - 2 y + 2 z ) + ( 2 y + 5 z) = - 6 + 15

Or,  12 x + 7 z = 9         ......D

Solving eq B and D

I.e 3 × ( 4 x - 3 z ) = - 13 × 3

or, 12 x - 9 z = - 39

So, (   12 x + 7 z ) - ( 12 x - 9 z ) = 9 + 39

or,  16 z = 48

∴   z = \frac{48}{16}

i.e  z = 3

put the value of z in eq D

So, 12 x + 7×3 = 9  

Or, 12 x = 9 - 21

or,  12 x = - 12

∴   x = -  \frac{12}{12}

I.e  x = - 1

Now, Put The value of z in eq C

or, 2 y + 5 z = 15    

or,  2 y + 5 × 3 = 15

Or,  2 y = 15 - 15

or,  2 y = 0  

∴  y = 0

Hence The solution of the equation are x = - 1 , y = 0 and z = 3  Answer

for every 140 feet that kelly rides on her bicycle, the wheels turn 20 times. about how many times do the wheels turn in 5 miles
lana [24]

Answer:

184800 times

Step-by-step explanation:

The first step is to find out how many times the wheels turn in one foot. The ratio of rotations per minute is 20:140. This can be simplified to 1:7, meaning there is 1/7 of a rotation for every 1 foot.

Next, we need to find out how many times they turn in one mile. The ratio is 1:7, and the 1 needs to become 5280. To do this, multiply both sides of the ratio by 5280. You will get 5280:36960, meaning there is 36960 rotations every mile (the ratio of miles to rotations is 1:36960).

Now, multiply 1:36960 by 5 to get the amount of rotations per every 5 miles. You will get 184800.

Final answer: the wheels turn 184800 times in 5 miles.
