Answer:
27 degrees
Step-by-step explanation:
they have relation with vertical opposite angle
The square root of 16=4, 4x2=8, x2=8.
F(x)= x+13
F(-2)= -2 +13
= 11
You plug in -2 for the x
Answer: 12 minutes
Step-by-step explanation:
Two rates for hoses A and B. FP is the Fish Pond.
A = 20 min/FP or (1/20)FP/min
B = 30 min/FP or (1/30)FP/min
The time in minutes, X, to fill one FP:
1FP = X*((1/20)FP/min) + X*((1/30)FP/min)
1FP = X*(1/20+1/30)FP/min
1FP = X*(2.5/30)FP/min
X = 12 minutes
Using Pythagoras:
12^2+5^2= 144+25=169
√169= 13
