The diagram represents an enlargement of a rectangle by a scale factor of 4.

Tpy6a [65]

Answer:

D. 16 inches by 8 inches

Step-by-step explanation:

We have been given an image of two rectangles and we are asked to find the dimensions of the enlarged rectangle.

Since we have been given that the original rectangle is enlarged b a scale factor of 4, so to find the dimensions of enlarged rectangle we will multiply the dimensions of original rectangle by 4.

$\text{Length of enlarged rectangle}=4\times 4\text{ inch}$

$\text{Length of enlarged rectangle}=16\text{ inch}$

$\text{Width of enlarged rectangle}=4\times 2\text{ inch}$

$\text{Width of enlarged rectangle}=8\text{ inch}$

Therefore, the dimensions of enlarged rectangle are 16 inches by 8 inches and option D is the correct choice.

the catering company is setting the table for a big event that will host 764 people when they set up the tables they need 2 fork

BARSIC [14]

Given:
child = 2 forks
adult = 5 forks
total number of forks = 2992
total number of people = 764

c + a = 764
2c + 5a = 2992

find the value of c using the 1st equation.

c = 764 - a

substitute c in the 2nd equation by its value

2c + 5a = 2992
2(764-a) + 5a = 2992

1528 - 2a + 5a = 2992
1528 + 3a = 2992
3a = 2992 - 1528
3a = 1464
3a/3 = 1464/3
a = 488

c = 764 - a
c = 764 - 488
c = 276

child = 276 ; adult = 488

2c + 5a = 2992
2(276) + 5(488) = 2992
552 + 2440 = 2992
2992 = 2992
