Answer:
AD = 12
Step-by-step explanation:
Find the diagram attached
From the given diagram, it can be inferred that;
AB = AD+DB and AD = DB
AB = AD + AD
AB = 2AD
AD = AB/2
Given that AB = 24
AD = 24/2
AD = 12
Hence the length of AD is 12
I believe the answer is 2
Answer:
The vertical depth travelled by the dolphin = 36 feet
Step-by-step explanation:
The dolphin is a fish that can jump out of the water and therefore it is used in circus shows and exhibitions.
Initially the dolphin is at a depth of 28 feet deep inside the water surface.It comes to water surface and then jumps out of the water to a height of 8 feet.
The vertical distance travelled by the dolphin can be found by taking the difference of final height and initial depth.
Vertical depth = final height - initial depth
= 8 - (-28)
= 36 feet
The vertical depth travelled by the dolphin = 36 feet
That would be B because 65 < 40 + 30
Answer:
2.09 × 10¹⁰ pounds
Step-by-step explanation:
The American chemical industry produces more than 9.5 million metric tons of sodium carbonate.
in this problem we have to calculate the amount in pounds of sodium carbonate are produced annually.
so we will convert the amount of 9.5 million metric tons to pounds.
Since in 1 metric ton = 2204.62 pounds
Hence, 9,500,000 metric ton = 2204.62 × 9,500,000
= 20943890000 pounds
= 2.09 × 10¹⁰ pounds
2.09 × 10¹⁰ pounds of sodium carbonate are produced annually.
