The students in Mr. Sanchez's class are converting distances measured in miles to kilometers. To estimate the number of kilomete

rs, Abby takes the number of miles, doubles it, then subtracts 20% of the result. Renato first divides the number of miles by 5, then multiplies the result by 8. Write an algebraic expression that shows the process that both students used. Abby's expression: Renato's expression:

Step-by-step explanation:

Abby’s Expression:

Double m, giving 2m. She then takes 20% of the result, which we can write 0.2(2m). Finally she subtracts this from 2m, giving 2m−(0.2)2m

2m − (0.2)2m

Renato’s Expression:

Divide m by 5, giving m ÷ 5 = m/5, and then multiplies the result by 8, giving:

8(m/5)

A(n)=a(1)+d(n-1),    d=a(16)-a(15)=-5-(-53)=48
a(15)=a(1)+d*(15-1),  
-53=a(1)+48*(15-1),

A theater group is having a carwash fundraiser. The group can only wash 45 cars with the amount of soap they purchased. Each car
Vesnalui [34]

Answer:

<h2>The domain for this function is c > 0 where c \in Z.</h2>

Step-by-step explanation:

The given function is

f(c)=7c

Where c represents cars. This function models the profits they make.

Now, as you can deduct already, we can define to different domains, the mathematical one and the reasonable one.

The reasonable domain is about all the useful values to the problem. For example, as we are talking about car, they can't wash -5 cars, so negative numbers are excluded. Similarly, they can't wash 6.75 cars, because that would imply an incomplete job.

Therefore, the domain for this function is c > 0 where c \in Z.

(Notice that we specify that the independent valur can only use whole positive numbers only).

In geometry, how do defined terms and undefined terms relate to each other

There are three words in geometry that are not formally defined. These three undefined terms are point, line and plane. 

POINT (an undefined term) 
In geometry, a point has no dimension (actual size). Even though we represent a point with a dot, the point has no length, width, or thickness. A point is usually named with a capital letter. In the coordinate plane, a point is named by an ordered pair, (x,y). 

LINE (an undefined term) 
In geometry, a line has no thickness but its length extends in one dimension and goes on forever in both directions. A line is depicted to be a straight line with two arrowheads indicating that the line extends without end in two directions. A line is named by a single lowercase written letter or by two points on the line with an arrow drawn above them. 

PLANE (an undefined term) 
In geometry, a plane has no thickness but extends indefinitely in all directions. Planes are usually represented by a shape that looks like a tabletop or wall. Even though the diagram of a plane has edges, you must remember that the plane has no boundaries. A plane is named by a single letter (plane m) or by three non-collinear points (plane ABC). 

Undefined terms can be combined to define other terms. Noncollinear points, for example, are points that do not lie on the same line. A line segment is the portion of a line that includes two particular points and all points that lie between them, while a ray is the portion of a line that includes a particular point, called the end point, and all points extending infinitely to one side of the end point. 

Defined terms can be combined with each other and with undefined terms to define still more terms. An angle, for example, is a combination of two different rays or line segments that share a single end point. Similarly, a triangle is composed of three noncollinear points and the line segments that lie between them. 

Everything else builds on these and adds more information to this base. Those added things include all the theorems and other "defined" terms like parallelogram or acute angle. <span>

11^2^3x=983298f+0220.2^2(38) <br> whats x.
Mazyrski [523]

Answer:

x=1638831.492383738758729e+23f+0

Step-by-step explanation:

(1123)(x)=983298f+(220.22)(38)

Step 1: Divide both sides by 8.954302432552374e+23.

8.954302432552374e+23x

8.954302432552374e+23

=

983298f+1842545.52

8.954302432552374e+23

x=

163883

1.492383738758729e+23

f+0
