The perimeter of a triangle is 240 cm.The lenghts of the sides are in the ratio 3:4:5.calculate the lenghts of the longest and shortest sides
Answer:
Longest : 100 , Shortest : 60
Explanation:
Step by step to answer :
Take 3+4+5 = 12
240/12 = 20
20 x 5 = 100 (Longest )
20 x 3 = 60 (Shortest )
20 x 4 = 80
100 + 60 + 80 = 240 correct

When might an ASDS be most useful and why?
Answer:
They're platforms in the ocean for spacecraft to land on. They can help save money and are reusable while the rocket normally just lands somewhere in the ocean and descends to the bottom of the ocean.
Explanation:
The ASDS is most useful when space craft must have to first land on something instead of allowing it to crash in the open ocean.
What are ASDS?The term ASDS refers to Autonomous spaceport drone ships which are used to await the landing of space crafts.

A wallet card for each family member
A) A list of friends for each family member
B) A map of the house
C) An enlarged picture of each family member
D) Two emergency contacts
Answer: A safe place in the neighborhood seems the most reasonable or D
Explanation:
A map of the house wouldn't make sense because im pretty sure they would know around there house. An enlarges picture of each family member would also not make sense because it is just not helpful at all. A wallet card for each family wouldn't help them in there situation. A safe place for the family pet would help the pet but not everyone in the house so no. A list of friends for each family member would really be useful.
Answer:
D
Explanation:
It sounds way more reasonable then any of these questions.
Organ systems of the human body interact to maintain a balanced internal environment. As blood flows through certain organs of the body, the composition of the blood changes because of interactions with those organs. State one change in the composition of the blood as it flows through the respiratory system.
The organ system interacts with each other to maintain the normal functioning of the body. The composition of blood changes due to this interaction. The change is the blood going out from the lungs is deoxygenated and the one coming to the lungs is oxygenated.
What is the interaction of the respiratory and circulatory systems?The respiratory system involves inhalation of oxygen and using this to release energy and exhalation of carbon dioxide.
The circulatory system is comprised of the heart and blood vessels. The heart pumps blood to different body organs through these blood vessels.
The transfer of oxygen is done with the help of blood. During this transfer, the composition of blood changes from being oxygenated means having oxygen to deoxygenated means having carbon dioxide.
Thus, in this way, the interaction changes the composition of blood.

Q5: Vestigal Structures
Q8: Enviorment
Explanation:
Q5:
Vestigial structures can provide insights into an organism's ancestry. For instance, the tiny vestigial leg bones found in some snakes reflect that snakes had a four-legged ancestor. The small leg-like structures of some snakes species, like the Boa constrictor, are vestigial structures.
Q8:Birds' beaks are the tools they have to use to gather food. The best adapted (fittest) to the available food have the best chance of surviving (not starving to death) and of having descendants. The different variations in these beak forms are each an experiment in natural selection.
Answer:
Vestigial structuresVariationsVestigial structures are structures that have a good function in the past, but are now no longer used. Let's say I have an unknown type of leg, then that leg in the future generation of my family no longer has that leg or it's changed. This is caused by variation and genetic changes, which we discuss right now.
In natural selection, variations are what likely causes beaks to vary. Variations are similar to a new thing, generation, or type of something. Like I have a lamp shade are there are tons of the same brand with different colors, that is a variation of one thing.
What is a potential benefit to mutations?
