A model represents its diameter as 8 um. What is the ratio of model size to
actual size?
O A. 1:1,000
B. 1:100
O C. 100:1
OD. 1,000:1

Answers

Answer 1
The actual size would be 1,000:1

thank youuuuu

Answer 2

A red blood cell has a diameter of approximately 8 micrometers, or 0.008 um. if a  model represents its diameter as 8 um.

The ratio of the model size to the actual size would be

What is a unit of measurement?

A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.

As given in the problem a red blood cell has a diameter of approximately 8 micrometers, or 0.008 um. if a  model represents its diameter as 8 um.

Size of the model /actual size = 8 /.008

                                                  =1000: 1

Thus, the correct answer is option D.

A parking lot is going to be 40 m wide and 100 m long. Which dimensions
could be used for a scale model of the lot?
A. 10 cm x 25 cm
B. 100 cm x 300 m
O C. 75 in x 225 cm
D. 25 cm x 75 cm


Answers

Answer: A

Explanation: You need to find the dimensions of the scale model of the lot that can be multiplied equally to get the original length. Basically 40 m and 100 m need to be divided by the same number to make the scale model evenly, and right off the bat you see that 10 and 25 could be multiplied by 4 and equal the original numbers. Hope this helps! Also sorry if it was kinda hard to understand lol, when i explain things its hard to get out of my own head ;P

You may not think earthquakes and volcanoes can go together, but they are unlikely friends, creating sensations under the earths surface. Most earthquakes occur because of the movement of tectonic plates previously described. Sometimes earthquakes happen below a volcano. This happens because magma, which is hot molten rock beneath the earths surface, pushes on rock until it breaks the rock and seeps into it. Then, the magma builds more pressure until it leaks more magma into the crack. Little earthquakes happen each time the rock breaks and lets in more magma. These little earthquakes are too small to feel. They are called harmonic tremors, perhaps because of their constant release of energy, like one long song played underground. What does the underlined analogy mean in this paragraph? A) When little earthquakes occur, they make sounds much like musical harmonies do. B) The same amount of energy is required to play harmonic songs as it is to create a little earthquake. C) Much like music that might play softly in the background, little earthquakes tremor underground without much notice. D) The tremors from multiple little earthquakes cause energetic beats much like musical harmonies do. please solve 6 number An isosceles triangle two sides equal is placed on top of the square as shown in the picture if the two equal sides are 22 ft long and each side is 39 ft Urgent please answer Which reforms, first introduced by the Populist Party in the late 1890s, had the most impact on expanding the influence of citizens on the government?Select three that apply.A adoption of bimetallismB direct election of senatorsC graduated income taxinitiativeD recall 3.
