Two squares have areas of 4 cm?
timofeeve [1]

Answer:

1/2

Step-by-step explanation:

First square area = 4cm^2, thus the side length is 2cm

Second square area = 16cm^2, thus the side length is 4cm

This gives a ratio of 2/4, simplifying yields 1/2

3 1/10- 2 5/6 in simplest form​
Allushta [10]

Answer:

\frac{4}{15}

Step-by-step explanation:

3  \frac{1}{10}  - 2 \ \frac{5}{6}

Convert the above mixed numbers to improper fractions through this simple approach: 3 × 10 + 1 /10 = 31/10. Similarly, 2 × 6 + 5 /6 = 17/6

\frac{31}{10}  -  \frac{17}{6}

Take the LCM of the denominators and simplify. LCM = 60. Thus, 60/10 = 6; 6 × 31 = 186. Also, 60/6 =10; 10×17 =170 all divide by 60:

=  \frac{186 - 170}{60}

Common factors between the numerator and denominator is 4, therefore 16/4 = 4 and 60/4 = 15.

=  \frac{16}{60}  =  \frac{4}{15}

Therefore the answer is 4/15 in simplest form.

Do these equations represent direct variation. If so please identify their constant of variation.
ozzi
Yes, these both are direct relationships and can be written like y = kx, where k is the constant of variation.

For the first equation, k = 10. For the second equation, k = -4/3. You find it by rearranging the equation into the form y=kx, and you use the coefficient of x for k.
