Calculate the unit rate for Machine A and Machine B. Determine which is the greater rate.

Damm [24]

Answer:

Machine B

Step-by-step explanation:

Since, Machine A covers $\frac{5}{8}$ square feet in $\frac{1}{4}$ hours,

Rate at which the Machine A is covering = $\frac{\frac{5}{8}}{\frac{1}{4}}$

= $\frac{5}{8}\times \frac{4}{1}$

= 2.5 square feet per hour

Machine B covers $\frac{2}{3}$ square feet in $\frac{1}{5}$ hours,

Rate at which the Machine B is covering = $\frac{\frac{2}{3}}{\frac{1}{5}}$

= $\frac{2}{3}\times \frac{5}{1}$

= $\frac{10}{3}$

= 3.33 square feet per hour

Therefore, Rate of Machine B is greater.

If anyone could answer this for me I would very much appreciate it

baherus [9]

Answer:

a3 = 45

Step-by-step explanation:

a1 = 20

an = a(n-1) *3/2 where n is the term number

a2 = a(2-1) *3/2

a1 *3/2

We know a1 = 20

a2 = 20*3/2 = 30

a3 = a(3-1) *3/2

= a2 *3/2

We know a2 = 30

= 30*3/2 = 45
