7 0

$1400 = $4000 × 7 × r / 100

$1400 = 28000 × r / 100

$ 1400 = $ 280 × r

rate = $1400 ÷ $ 280

rate = 5

on Serena's 10th birthday her mom was 3 times her age.How old will Serena and her mom be when her mom's age times 0.5 equals Ser
alex41 [277]
When Serena is 10, her mom is 3*10=30. Her mom is 20 years older than Serena.

If her mom's age divided by half is equal to Serena's, then she will be twice as old as Serena.

20 + 20 = 40
20 * 2 = 40

Serena will be 20, her mom will be 40.

what is the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube
Dmitrij [34]
Let the least possible value of the smallest of 99 cosecutive integers be x and let the number whose cube is the sum be p, then

\frac{99}{2} (2x+98)=p^3 \\  \\ 99x+4,851=p^3\\ \\ \Rightarrow x=\frac{p^3-4,851}{99}

By substitution, we have that p=33 and x=314.

Therefore, <span>the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube is 314.</span>

30 pts for this one.... (only if you give a reasonable answer no BS)
Keith_Richards [23]

Answer:

  1. y = 3000x + 40000
  2. a) the base salary of the salesperson
  3. a) the commission per subscription

Step-by-step explanation:

Slope intercept form is found by [ y = mx + b ] where m = slope and b = y-intercept. We are given that a salesperson gets $40000 as a base salary. Since this value doesn't change it is the starting value, in other words the y-intercept. The salesperson also gets $3000 for every subscription they sell. Since this amount grows at a constant rate, that is the slope. Now, we can write the slope intercept form of [ y = 3000x + 40000 ].

Best of Luck!
