C^2=a^2+b^2-2abcosC
13^2=10^2+11^2-2×10×11×cos(°)
169=100+121-220cos(°)
220cos(°)=100+121-169
220cos(°)=52
cos(°)= 13/55
°=cos-1(13/55)
°=76.328°

In standard form the two equations are
7x +y = 5
7x +y = -5

The equations describe lines that are parallel.

Answer:1/16 for each of us

Step-by-step explanation:

Since only 1/4 is left and you and the teachers are splitting it up,you’d get 1/16 each because the half of 1/4 (1/8) was split into 2 (1/16)

I will pick brainliest first come, first serve! I need help! Give me an answer that makes sense!

nordsb [41]

Step-by-step explanation:

Total amount of apples in one bag:

$x + y + z$

Hence, total amount of apples in two bags:

$2(x + y + z)$

or

$2x + 2y + 2z$

or

$x + x + y + y + z + z$

Hence, B, D and E are correct.

A is incorrect because you are adding 2 more apples on top of the total amount of apples in one bag, and you cannot assume that there are 2 apples in each bag.

C is incorrect because you are multiplying the apples together, but you are supposed to add them up to find the total.

F is incorrect because you are finding 1/2 a bag.
