Answer:
169 cm²
Step-by-step explanation:
Recall that the area of the largest square is |PR|²
Also recall from Pythagoras Theorem that:
|PQ|² +|QR|² =|PR|² ---->1
Also we have that the sum of the areas of the three squares is 338 square centimeters.
This implies that:
|PQ|² +|QR|² +|PR|²=338---->2
Put equation (1) into (2)
|PR|²+|PR|²=338
Simplify to get:
2|PR|²=338
Divide both sides by 2 to get:
|PR|²=338
|PR|²=169
After 2 minutes, temperature = 9/10 x 70 = 63F
After 4 minutes, temperature = 9/10 x 63 = 56.7F
After 6 minutes, temperature = 9/10 x 56.7 = 51.03F
Answer:
5.9 hours
Step-by-step explanation:
1/13+1/11=1/x
looking for x
x= 5.9
are you clear?
