In the blueprint for A rectangular balcony is 1 inch by 1.75 inches if the actual length is 7 feet what is the perimeter

Answers

Answer 1
Answer:

Answer:

22 feet

Step-by-step explanation:

Given

  • In blue print,dimensions of rectangular balcony are, length(l)=1.75inch and breadth(b)=1inch
  • The actual length(L)=7 feet

To find the actual perimeter, we need the breadth of balcony(B)

The ratio of length to breadth in blue print must be equal to the ratio of actual length to breadth

⇒

\frac{\text{length of rectangular balcony in blueprint}}{\text{breadth of rectangular balcony in blueprint}} =\frac{\text{length of rectangular balcony actually}}{\text{breadth of rectangular balcony actually}}

(l)/(b) =(L)/(B) \nB* l=L * b\nB= (L * b)/(l)=(7 * 1)/(1.75) =4

Therefore Breadth actually=4 feet

⇒Perimeter

=2*(length+breadth)\n=2*(7+4)\n=2*(11)\n=22

Therefore perimeter of rectangular balcony= 22 feet

Jack crawled 4 ft and Christine crawled 3⁄4 the distance Jack crawled. If you add the distance they each crawled together, what is the total distance the two children crawled. (Write the answer in inches.)

Answers

Before going into the details of the problem, let us first write down the most important information required for solving this problem.
1 ft = 12 inches
The distance that was crawled by Jack = 4 ft
                                                                = (4 * 12) inches
                                                                = 48 inches
The distance crawled by Christine = 3/4 of the distance crawled by Jack
                                                         = (3/4) * 48 inches
                                                         = 3 * 12 inches
                                                         = 36 inches
Then
The total distance crawled by the two children's = (48 + 36) inches
                                                                             = 84 inches
So Jack and Christine together crawled a distance of 84 inches.
Christine crawled:
4 ft* (3/4)= 3 ft.

4 ft+ 3ft= 7ft.

The total distance the two children crawled is 7ft~

WILL MARK BRAINLIEST!The multipliers of this system of equations have been determined to create opposite terms of the y-variable.

4 (one-fourth x minus three-fourths y = 34) right-arrow x minus 3 y = 136
24 (three-fourths x + one-eighth y = negative 12) right-arrow 18 x + 3 y = negative 288

Answers

Answer:

thus, x=-34 and y=170/-3

Step-by-step explanation:

4((1/4)*x-(3/4)*y)=34

x-3y=136

24((3/4)*x+(1/8)*y)=12

18x+3y=-288

4x-3y=34⇒x-3y=136

18x+3y=12⇒18x+3y=-288

lets solve 4x-3y=34⇒x-3y=136 first:

4x-3y=34

x-3y=136

4x-3y=34    

-x+3y=-136

3x=-102

x=-102/3

x=-34

lets plug in x to one of the equations, since both equations are equal to each other:

4x-3y=34

4(-34)-3y=34

-136-3y=34

-3y=170

y=170/-3

now lets solve: 18x+3y=12⇒18x+3y=-288

18x+3y=12

18x+3y=-288

18x+3y=12

-18x-3y=288

0\neq300

so, this system doesn't work

thus, x=-34 and y=170/-3
