Answer:
degree measure of arc AB = 120°
length of arc AB = 40π/3 in.
Step-by-step explanation:
arc AB has the same measure as its central angle. So, arc AB = 120°
120 is 1/3 of 360, Therefore, the length of arc AB is 1/3 of the circumference.
Therefore, the
length of arc AB = 1/3πd = 1/3π(40) =
= 40π/3 in.
You can either express the decrease that happened in the account savings by integers. To do this you simply subtract 55$ from the initial amount in the account. This is expressed as:
initial amount - 55$
or, you can express the decrease in the form of percentage by calculating how much is 55$ from the total amount. This is expressed as:
(5/initial amount) x 100
Answer:
i guess it's the second one, 16x2+9y2, since they are both raised to 2 and they are binomial
9 because every ten plants is equal to 3 gallons. 30 plants are equal to 9 gallons.
tell me if if helps.
12)
9/10 / 3/4
= 9/10 * 4/3
= 12/10
= 6/5
