Answer:

The scale factor is 0.4 - FALSE; The scale factor is 2.5 - TRUE

Step-by-step explanation:

Since the arrow points from the smaller rectangle to the larger one, this means the scale factor must be greater than 1, since the figure is enlarged.

To find the factor that the figure is enlarged, divide the resulting length by the original length:

5/2 = 2.5

Take the length of the larger divide it by the smaller

Clayton is at most 2 meters above sea level. Using C for Clayton, which inequality correctly represents this statement?
Nataly [62]

Answer:

C ≤ 2

Step-by-step explanation:

Given that :

Clayton is at most 2 meters above sea level ;

Let Clayton = C

Clayton's distance can be represented by the inequality :

2 meters above sea level is positive, +2

At most 2 meters above sea level means, Clayton could be anywhere between + 2 metwrs but not more than 2 meters

Hence, Clayton's distance can be represented by the inequality :

C ≤ 2

Melissa and Emily are playing at the pool.They have three different measuring jars for; liters, cups, and pints. They find that
Deffense [45]
7 cups + 3 litres = 9.8 pints 
7c+3l=9.8p ⇒ Equation 1

5 litres - 9 cups = 6 pints
5l-9c=6p ⇒ Equation 2

Relationship between cups and litres
Rearranging equation 1 to make pints the subject
7c+3l=9.8p
p= \frac{7c+3l}{9.8} ⇒ substitute this into Equation 2

5l-9c= \frac{7c+3l}{9.8}
49l-88.2c=7c+3l
49l-3l=7c+88.2c
46l=95.2c
l=2.1c

Hence, 1 litre = 2.1 cups

Relationship between cups and pints
Rearrange equation 1 to make litres the subject
7c+3l=9.8p
3l=9.8p-7c
l= \frac{9.8p-7c}{3} ⇒ Substituting this into Equation 2

5( \frac{9.8p-7c}{3})-9c=6p
\frac{49p-35c}{3}-9c=6p
\frac{49}{3}p- \frac{35}{3}c-9c=6p
\frac{49p}{3}-6p= \frac{35}{3}+9c
\frac{31}{3}p= \frac{62}{3}c
p=2c

Hence, 1 pint = 2 cups

Relationship between pints and litres
Rearranging equation 1 to make cup the subject

7c=9.8p-3l
c= \frac{9.8p-3l}{7} ⇒ subsitute this into equation 2

5l-9( \frac{9.8p-3l}{7})=6p
5l- \frac{63}{5}p+ \frac{27}{7}l=6p
5l+ \frac{27}{7}l=6p+ \frac{63}{5}p
\frac{62}{7}l= \frac{93}{5}p
l=2.1p

Hence, 1 litre = 2.1 pints
