How big is the target in compound archery?
The target in a compound event is set at 50 metres. The target face is 80cm in diameter with the innermost 10-point ring 8cm in diameter. A barebow is the most primitive form of bow in archery, with archers allowed no stabilisers or sight pins to shoot at their targets.
4 is the answer because you multiply
Answer:
x = -1, y = 7
Step-by-step explanation:
8x + 3y = 13
3x + 2y = 11
Multiply the first equation by -2 and the second equation by 3. Then add them.
-16x - 6y = -26
(+) 9x + 6y = 33
--------------------------
-7x = 7
x = -1
Now substitute x = -1 in the first original equation and solve for y.
8x + 3y = 13
8(-1) + 3y = 13
-8 + 3y = 13
3y = 21
y = 7
Answer: x = -1, y = 7
Answer:
This is an indirectly proportional relation, because the food will last less if the number of animals increases.
What we can do is a rule of three, as we know that the food lasts 30 days for 100 animals, and we want to know how many days does it last for 120:
30 days -- 100 cows
x days -- 120 cows
As it's an inderect rule of three, x =
= 25.
The food will last 25 days for them.
You have to make the lines congruent so it is 23by10
