Answer:
1. A fossil is the remains of a once living animal from long ago. Fossils can be Bones, Shell, Exoskeleton, stone prints and more.
2. A observation is something seen and physically recorded as in a inferences is a guess or idea that needs to be supported BY EVIDENCE.
4. For a fossil to be fossilized it needs to be covered in sediment which prevents the fossil from decaying.
5. I THINK that's false
Answer:
x = 
Step-by-step explanation:
given
=
( cross- multiply )
5(x + 1) = 33
5x + 5 = 33 ( subtract 5 from both sides )
5x = 28 ( divide both sides by 5 )
x = 
Answer:
The length of BC = 28 units
Step-by-step explanation:
* In triangle ABC
∵ Angles B and C are congruent
∴ m∠B = m∠C
* In any triangle if two angles are equal in measure, then the triangle is isosceles means the two sides which opposite to the congruent angles are equal in length
∴ AB = AC
∵ AB = 4x - 7
∵ AC = 2x + 7
∴ 4x - 7 = 2x + 7 ⇒ collect like terms
∴ 4x - 2x = 7 + 7
∴ 2x = 14 ⇒ divide both sides by 2
∴ x = 14 ÷ 2 = 7
* Now we can find the length of BC
∵ The length of BC = 4x ⇒ substitute the value of x
∴ The length of BC = 4 × 7 = 28 units
They are similar. I don't remember what it is called but it is 100% ALWAYS true that the angles of a triangle must add up to 180 degrees. Always. If you have two angles, that are 60 degrees, the other must always be 60. again, always. So, They are similar by their angles.
Answer:
To fill the aquarium, she will need to fill the container 320 times.
Step-by-step explanation:
This question can be solved using a rule of three.
Each pint has 0.125 gallons.
So each fill of the container contains 0.125 gallons. How many fills are needed for 40 gallons?
1 fill - 0.125 gallons
x fills - 40 gallons



To fill the aquarium, she will need to fill the container 320 times.
