pickupchik [31]

Answer:

The length of the third side of the triangle is $7\sqrt{91}\ units$

Step-by-step explanation:

Let

c ----> the length of the third side of the triangle

we know that

Applying the law of cosines

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

we have

$a=42\ units\\b=35\ units\\C=120^o$

substitute the given values

$c^2=42^2+35^2-2(42)(35)cos(120^o)$

$c^2=2,989-2,940cos(120^o)$

$c^2=4,459\\c=\sqrt{4,459}\ units\\c=7\sqrt{91}\ units$

A person has a bag containing dimes and nickels. There are a total of 120 coins in the bag, and the total value of the coins is

telo118 [61]

Answer:

There are 65 dimes. There are 55 nickels.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of dimes

y is the number of nickels.

There are a total of 120 coins in the bag

This means that x + y = 120.

The total value of the coins is $9.25.

The dime is worth $0.10 and the nickel is worth $0.05. So

0.1x + 0.05y = 9.25

System:

$x + y = 120$

$0.1x + 0.05y = 9.25$

From the first equation:

$y = 120 - x$

Replacing in the second:

$0.1x + 0.05y = 9.25$

$0.1x + 0.05(120 - x) = 9.25$

$0.1x + 6 - 0.05x = 9.25$

$0.05x = 3.25$

$x = \frac{3.25}{0.05}$

$x = 65$

$y = 120 - x = 120 - 65 = 55$

There are 65 dimes. There are 55 nickels.
