A photo 5 inches wide and 8 inches long is enlarged. How long is the new photo if it is How wide is the new photo if it is (1)12
ddd [48]

Answer:

1) 7.5 inches, 2) 12.5 inches, 3) 6.25 inches

Step-by-step explanation:

In the problem statement, it is stated that the original dimensions of the photo are 5 inches by 8 inches. The 3 parts of the problem are asking what the respective width of the new photo would be given a different length measurement.

Using the ratio (5:8) you can set up an equation with x representing the missing measurement, and cross multiply to calculate the new width.

1) If the length is 12 inches, the width is 7.5 inches

\frac{5}{8} = \frac{x}{12}

60=8x

\frac{60}{8} =x

7.5 = x

2) If the length is 20 inches, the width is 12.5 inches

\frac{5}{8} = \frac{x}{20}

100=8x

\frac{100}{8} =x

12.5 = x

3) If the length is 10 inches, the width is 6.25 inches

\frac{5}{8} = \frac{x}{10}

50=8x

\frac{50}{8} =x

6.25 = x

Lola needs to sign 96 invitations. Using a stopwatch that measures time to tenths of a second, it takes Lola 5.3 seconds to sign
andrew11 [14]

Answer:

8.48\ minutes

Step-by-step explanation:

we know that

it takes Lola 5.3 seconds to sign her full name

so by proportion

Find how many seconds take Lola  to sign 96 invitations

\frac{5.3}{1}\frac{seconds}{invitation}=\frac{x}{96}\frac{seconds}{invitations} \\ \\ x=96*5.3\\ \\x= 508.8\ seconds

Convert seconds to minutes

Remember that

1\ minute=60\ seconds

so

508.8\ seconds=508.8/60=8.48\ minutes
