bixtya [17]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In point A:

The two-point C and y is given, where C is the scale drawing lengths  and y is the actual mural lengths so, the formed equation is:  

\to \frac{c}{y}=\frac{2}{5}

In point C :

Using the value of the scale:

let  1 feet: 20 feet

therefore the equation is:

\to \frac{c}{y}=\frac{1}{20}

The size of c will be the length of:

\to c= \frac{y}{20}\\\\\to c= \frac{8}{20}\\\\\to c= 0.4\\

The diagram c scale width will be:

\to c= \frac{y}{20}\\\\\to c= \frac{15}{20}\\\\\to c= 0.75\\

Dvinal [7]

Let width be W


Then length = 5W

P=2L+2W

P< 96cm

Then the Perimeter  of the rectangle is equal to

(2L+2W)< 96

2*(5W)+2W)≤96


Therefore, 2w+2⋅(5w)≤96


should be your answer

dolphi86 [110]
You will take 140 times 5 since that is the amount she made so you times it buy the price she earns then after you do that subtract it buy 650 since that is what you have to pay
140 x 5 = 700
700 - 650 = 50

Raul drove 80 miles. This represents 50% of his entire trip. What is the total number of miles in Raul's trip?
Dafna11 [192]
If 80 miles is 50% of his trip, then you know that 80 miles is only HALF of his entire trip. To get the distance Raul traveled in total, simply double the 80 miles. This would be 160 miles. 
Raul traveled a total of 160 miles in his trip.
