A ray is a defined term because it

Answers

Answer 1

Answer:

A ray is a defined term because it extends infinitely in one direction from an endpoint. A line is an infinite series of points in a row and it does not occupy any space. They are also called one dimensional since the direction is in one dimension. A point has a location but no specific size. It can describe a location but you can never determine its actual size. Imagine the point at the end of the previous sentence. And then imagine it getting smaller and smaller until it disappears. We can only use a dot to represent the point.

The equatorial diameter of a model of earth is 25.6 cm. What is the total surface area of the model

Answers

Answer:

$2059.7\,\,cm^2$

Step-by-step explanation:

Diameter of a model of earth (D) = 25.6 cm

Radius of a model of earth (r) = $(D)/(2)=(25.6)/(2)=12.8\,\,cm$

Earth has the shape of a sphere.

Total surface area of a sphere = $4\pi r^2$

Put $\pi=(22)/(7)\,,\,r=12.8\,\,cm$

So,

Total surface area of the model $=4((22)/(7))(12.8)^2=2059.7\,\,cm^2$

85% of what number equals 17

Answers

percent means parts out of 100
85%=85/100=0.85
'of' means multiply

therefor
85% of x equals 17 means
0.85 times x=17
divide both sides by 0.85
x=20

the number is 20
