Answer:
6 chickens, 11 cows.
Step-by-step explanation:
x - chickens
y - cows
x + y = 17
2x + 4y = 56 <-- chickens have 2 legs, cows have 4.
y = -x + 17
Substitute (-x+17) for y in the second equation.
2x + 4(-x + 17) = 56
2x -4x + 68 = 56
2x = 12
<u>x = 6 chickens</u>
Now substitute 6 for x
6 + y = 17
<u>y = 11 cows</u>
Answer:
Option D
Step-by-step explanation:
From the picture attached,
m∠K ≅ m∠C [Given]
m∠L = m∠D [Given]
By AA property of similarity,
Both the triangles ΔDEC and ΔLMK are the similar triangles.
Option D will be the correct option.
Answer:
C. 15 cm
Explanation:
The radius is the same in a circle. PA and PB has same length of 8 cm.
In order to find AC, find the length of PA and PC.
Here given:
- PC = PB + BC = 8 cm + 9 cm = 17 cm
Hence solve using Pythagoras theorem:
0.5 ,0.6 ,0.7 ,0.8 ,0.9 ,1,1 .1 ,1.2 ,1.3
The answer is either a or d but we know she did all of this for more than 52 minutes.
