Answer:
FIRST.
64 square inches matches to a cross section parallel to the base of a right rectangle prism that is 3 inches long, 7 inches wide, and 11 inches tall
This is shown in the first figure below. A right rectangular prism where every edge connecting its base and the opposite face makes right angles with both faces. Since the tall is the side that measures 11 inches, then the base is formed by 3 inches long and 7 inches wide. Therefore, the area of this shape can be found as the area of a rectangle, which is: 21 in squared.
SECOND.
64 square inches matches to a cross section parallel to the base of a cube whose edges are 8 inches long.
This is shown in the second figure below. A cube is a prism whose sides all have the same length and in this case is 8 inches. We name cross section is to the slice that cuts through a solid. If the cross section is parallel to the base of a cube, then it forms a square with length . Therefore, the area of this shape can be found as the area of a square, which is: 64 in squared.
Third.
7 square inches matches to a cross section passing through the diagonal of opposite faces of a cube with edges that are 7 inches long and a diagonal that is approximately 10 inches
This is shown in the third figure below. As you can see, the cross section passes through the diagonals of the base and the top of the cube that are two opposite faces. This form a rectangle having sides where:
So: 70 in squared
FOURTH.
300 square inches matches to a cross section perpendicular to the base and passing through the diagonals of the base and opposite face of a right rectangular prism that is 24 inches wide, 7 inches long, and 12 inches tall and measures 25 inches along the diagonal of the base.
This is shown in the fourth figure below. The cross section passes through the diagonals of the base and the top of the right rectangular prism. They are opposite to each other, so the shape of the cross section is a rectangle whose sides are where:
So: 300 in squared.

for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm

If two sectors have an area of 12π square units, and one sector is from a circle with radius 6 units, while the other is from a circle with a radius of 4 units, how do the central angles for these sectors compare?
Answer:
Thus, the ratio of the central angles is 4 : 9.
Step-by-step explanation:
Area, A = 12 π square units
radius, R = 6 units
radius, r = 4 units
Area of sector is given by
[tex]A=\frac{\theta }{360}\times \pi r^{2}[/tex]
For first sector
[tex]12\pi=\frac{\theta }{360}\times \pi \times 6^{2}\\\\\theta = 120^{o}[/tex]
For second sector
[tex]12\pi=\frac{\theta' }{360}\times \pi \times 4^{2}\\\\\theta' = 270^{o}[/tex]
So, the ratio is
[tex]\frac{\theta}{\theta'}=\frac{120}{270} =4 : 9[/tex]
Answer:
4 : 9
Step-by-step explanation:
Given:
Two sectors, each has an area of 12pi, but with radii r1=6 and r2=4 units.
Find ratio of central angles.
Solution:
Let A = central angle
Area of a sector = pi r^2 (A/360)
Since both sectors have the same area,
pi r1^2 (A1/360) = pi r2^2 (A2/360)
simplifying
A1 r1^2 = A2 r2^2
Therefore
A1 : A2 = r2^2 : r1^2 = 4^2 : 6^2 = 4 : 9

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:
1) Fossils are the preserved remains, or traces of remains, of ancient organisms. Fossils are not the remains of the organism itself! They are rocks.
A fossil can preserve an entire organism or just part of one. Bones, shells, feathers, and leaves can all become fossils.
Fossils can be very large or very small. Micro-fossils are only visible with a microscope. Bacteria and pollen are microfossils. Macrofossils can be several meters long and weigh several tons. Macrofossils can be petrified trees or dinosaur bones.
Preserved remains become fossils if they reach an age of about 10,000 years. Fossils can come from the Archaeaean Eon (which began almost 4 billion years ago) all the way up to the Holocene Epoch (which continues today). The fossilized teeth of wooly mammoths are some of our most "recent" fossils. Some of the oldest fossils are those of ancient algae that lived in the ocean more than 3 billion years ago.
2)It is important to understand that an observation is something that can be easily seen whereas an inference is a guess or idea that needs to be supported by evidence. For example, students can make the observation that a gecko has four short, skinny legs.
3) I don't know what the simulation is, but I'm guessing that one observation could be made about the amount of time that a certain amount of organisms fossilize on the beach, the floodplain and the upper river.
4) Sediment (soon after death)
5) True

A tree in John's backyard has been growing for 4 1/2 years. The tree is 4/5 meters tall. What is the unit rate in meters per year? No links or I will report. Answer in a fraction or mixed number in simplest form or whole number. Answer fast please.
Answer:
5 127/200 meters
Step-by-step explanation:
4 1/2 = 4 5/10 | 4/5 = 8/10
--------------------------------------
4 5/10 = 4.5 | 8/10 = 0.8
--------------------------------------
4.8 divided by 0.8 = 5.625
--------------------------------------
5.635 = 5 635/1000
635/1000 divided by 5 = 127/200
--------------------------------------
5 + 127/200 = 5 127/200
The unit rate in meters per year is 8/45 meter/year.
Given that, a tree in John's backyard has been growing for [tex]4\frac{1}{2} = \frac{9}{2}[/tex] years. The tree is 4/5 meters tall.
What is the unit rate?Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.
Now, unit rate = 4/5 ÷ 9/2
= 4/5 × 2/9
= 8/45 meter per year
Therefore, the unit rate in meters per year is 8/45 meter/year.
