For the pan one, you would colour all 4 of them (lightly) because she used all 4. For the cutting them up one, you did it right. For the next one, the first thing you need to do is colour 1 slice on the first triangle, on the 3rd on colour 2 slices, on the 2nd one colour two slices, and on the 4th one colour 4 slices. (Colour these ones hard.)
Answer:
BD = 12.1 (nearest tenth)
Step-by-step explanation:
∆ABC is an isosceles triangle, since it has two equal sides, AB and BC. Also, this means that <BAD and <BCD = 60° each.
BD divides ∆ABC into two equal parts.
Apply trigonometric ratio to find BD.
Reference angle = <BAD = 60°
Adjacent = AD = 7
Opposite = BD
Thus, we would have:
tan 60 = opp/adj
Tan 60 = BD/7
7*Tan 60 = BD
12.1 = BD
BD = 12.1 (nearest tenth)
Answer:
300=initial time and 0.05 is the amount of time shaved off of the initial time to run the marathon
Step-by-step explanation:
2p-14=4(p+5)
Step 1, parentheses
2p-14=4p+20
Subtract 20 from each side of the equation
2p-34=4p
Subtract 2p from each side
-34=2p
Divide each side by 2
-17=p
A unit fraction is a rational number written as a fraction where the numerator is one and the denominator is a positive integer. A unit fraction is therefore the reciprocal of a positive integer, 1/n. Examples are 1/1, 1/2, 1/3, 1/4 ,1/5, etc.
