The denominator of the seventh term is
125
216
343
512

Thus, Third option is correct.

Step-by-step explanation:

Since we have given that

So, we can see the pattern:

General term of the series is given as

So, we just put the value of n = 7, to get the required denominator:

Hence, the denominator of the seventh term is 343.

Thus, Third option is correct.

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
