This is a similarity and congruence question.
When shapes are similar, their angles are equal but their sizes are proportionate
So we can say this:
Angle GHE or z = Angle CDA
Angle GHE or z = 110
Answer would be 110
Answer:
878 years
Step-by-step explanation:
The amount of carbon-14 present in animal bones after t years is given by:
If the bone has lost 10% of its carbon-14.
Its Initial Amount of C-14, =100%=1
Present Amount, P(t)=(100-10)%=90%=0.9
Substituting these values in the model
The bone is 878 years old.
Answer:
Every hour the tempreture goes up 2.5 degrees
Step-by-step explanation:
The time (hours) goes up in segments of 2, while the degrees goes up in segments of 5. This means that in order to get the correct rate of change, you have to divide both numbers by 2.
Answer:
(9 1/2)/(4 3/4)
19/2)/19/4) Divide:
19*4/2*19= 76/38= 2 rooms
Step-by-step explanation:
