Brian wants to put this picture in the school newspaper in a space that is 5 inches tall. if he enlarges the picture proportionally so that it is 5 inches tall, how many square inches will it cover in the paper? (picture- height=2 1/2 length=1 1/4)

The enlarged picture will cover 12.5 square inches in the paper.

Step-by-step explanation:

For the original picture, height is inches and length is inches.

The height of the enlarged picture is 5 inches.

Suppose, the length of the enlarged picture is   inches.

As he enlarges the picture proportionally, so the equation according to the ratio of height and length will be.......

Thus, the length of the enlarged picture is 2.5 inches.

So, the area of the enlarged picture

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
