515 + 250= $765
175 x 4= $700
765 + 700= $1465
$1465 / 4 = $366.25

Each friend contributed $366.25

Answer:

366.

Step-by-step explanation: $515 and $250 is $765. $175 times 4 hours of playing is $700. $700 Plus $765 is $1465. $1465 divided by 4 equals $366.25 from each friend.

-15 = m

Step-by-step explanation:

-16 = -1 + m

-16 + 1 = m

-15 = m

Why does -1 became +1 , It is because you are adding 1 on both side so that we can cancel out the -1 and it will rest the m.

like this;

+1 -16 = -1 + m +1

-16 + 1 = (0 or nothing) + m

-15 = m

In triangle PQR, PR = 23mm, QR = 39mm, and m&lt;R = 163 degrees. Find the area of the triangle to the nearest tenth.
Schach [20]

Answer: 131.1287 square mm (approx)

Step-by-step explanation:

The area of a triangle,

A=\frac{1}{2} \times s_1\times s_2\times sin \theta

Where s_1 and s_2 are adjacent sides and \theta is the include angle of these sides,

Here PR and QR are adjacent sides and ∠R is the included angle of these sides,

Thus, we can write,

s_1 = PR= 23\text{ mm}, s_2=QR=39\text{ mm} and \theta = 163^{\circ},

Thus, the area of the triangle PQR,

A=\frac{1}{2} \times 23\times 39\times sin163^{\circ}

A=\frac{262.257419136}{2} = 131.128709568\approx 131.1287\text{ square mm}
