Answer:
in my knowledge I think 13
we know the turtle is half as old as her parrot
so if we divide 10 by 3/4 we can get how old the turtle is
3/6 because absolute value of any number has to be positive and you have to subtract the 2 answers to find the distance
4>-3
-2>-5
1=1
They want to make sure you understand inequalities and know how to use the inequality signs.
Answer:
∠BAD=20°20'
∠ADB=34°90'
Step-by-step explanation:
AB is tangent to the circle k(O), then AB⊥BO. If the measure of arc BD is 110°20', then central angle ∠BOD=110°20'.
Consider isosceles triangle BOD (BO=OD=radius of the circle). Angles adjacent to the base BD are equal, so ∠DBO=∠BDO. The sum of all triangle's angles is 180°, thus
∠BOD+∠BDO+∠DBO=180°
∠BDO+∠DBO=180°-110°20'=69°80'
∠BDO=∠DBO=34°90'
So ∠ADB=34°90'
Angles BOD and BOA are supplementary (add up to 180°), so
∠BOA=180°-110°20'=69°80'
In right triangle ABO,
∠ABO+∠BOA+∠OAB=180°
90°+69°80'+∠OAB=180°
∠OAB=180°-90°-69°80'
∠OAB=20°20'
So, ∠BAD=20°20'
What you do is add up all the values, then divide by the number of values.
The average of the data is
4.8575.
