Write an equation to represent the relationship between the step number, n, and the number of dots, y.
KengaRu [80]

The equation that represents the relationship between step number and the number of dots is y=5^n.

Solution:

Let the number of dots be y.

Step number 0: Number of dots = 1

y = 1

Using exponential rule: a^0=1

y=5^0

Step number 1: Number of dots = 5

y = 5

y=5^1

Step number 2: Number of dots = 25

y = 25

y=5^2

Step number 3: Number of dots = 125

y = 125

y=5^3

Note that in step number 0 the power is 0, 1st step power of 5 is 1, 2nd step power of 5 is 2 and the third step power of 5 is 3.

If the process goes on up to n steps, then power of 5 is n.

∴ Step number n:

y=5^n

Number of dots = 5^n.

Hence the equation that represents the relationship between step number and the number of dots is y=5^n.

Tamiku [17]

Answer:

\large\boxed{x=\dfrac{8}{9}}

Step-by-step explanation:

9x-8=0         <em>add 8 to both sides</em>

9x-8+8=0+8

9x=8          <em>divide both sides by 9</em>

\dfrac{9x}{9}=\dfrac{8}{9}\\\\x=\dfrac{8}{9}

Joshua sells 13 toys per hour. Sarah sells 16 toys per hour. This week Sarah sold an additional 20 toys. Write an expression tha
snow_tiger [21]
Assuming that they each work 24hrs a day 7 days a week (I haven't got anything else to go on...sorry) to find the total for Joshua you must first multiply 13x24 = 312, for the toys sold per day, and then 312x7 = 2184, for the number of days per week. so j = 2184
then for Sarah's total we must first multiply 16x24 = 384 for the toys sold per day and then 384x7 = 2688 for the toys sold per week. and 2688+20 = 2708 for the extra 20 she sold. so s = 2708

REMEMBER, THIS IS ASSUMING THEY WORK 24/7 MEANING THEY WORK 168 HOURS PER WEEK. 

IF YOU NEED A DIFFERENT ANSWER LET ME KNOW AND I'LL TRY TO FIX IT. IF YOU LET ME KNOW THE HOURS THEY WORKED I CAN DO TAT FOR YOU AS WELL.
