These are just multiplications.  For percents we have to move the decimal point two places. I assume calculators are OK.

2.

19.6% of 244 = .196(244) = 47.824

3.

20% of 75 = .2 (75) = 75/5 = 15

Didn't need a calculator for that one.

Find the 52nd term of the given arithmetic sequence-30, -38, -46, -54...
torisob [31]

The sequence is given to be:

-30,-38,-46,-54...

The nth term of an arithmetic sequence is calculated using the formula:

a_n=a_1+(n-1)d

where a₁ is the first term, n is the number of terms, and d is the common difference.

From the given sequence, the following parameters can be gotten:

\begin{gathered} a_1=-30 \\ d=-38-(-30)=-8 \end{gathered}

Therefore, the parameters can be substituted into the formula to find the 52nd term:

\begin{gathered} n=52 \\ \therefore \\ a_{52}=-30+(52-1)(-8) \\ a_{52}=-30+51(-8)=-30-408 \\ a_{52}=-438 \end{gathered}

The 52nd term is -438.

6(-p+8)= -6p + 12<br> Can someone help me please
Leno4ka [110]

Multiply the bracket by 6

6(-p+8)= -6p + 12

-6p+48= -6p+12

Move -6p from right side to left side

Sign changes from -6p to +6p

-6p+6p+48= -6p+6p+12

48= 12 ( No solution )

Answer : No solution

Danny’s supermarket has 1 litter water bottles normally priced at $1.50 reduced 25%
geniusboy [140]

Answer: Danny's supermarket

Step-by-step explanation:

Danny's price- 0.75x1.5= $1.12 for 1 liter water bottle

Marta's price- $1.50 for 1.25 liter water bottle

1.12x1.25=1.40, if Danny was selling a 25% bigger bottle(making the bottle size equal to Marta's) it would cost $1.40, the lower price

Please help me with this word problem!!!
Inessa [10]

Answer:

The number of customers needed to break even is

\simeq 6775.

Step-by-step explanation:

Rent per month = $ 7200

Rent per year, $ 7200 \times 12

                        = $ 86400 -------------(1)

Insurance per year = $ 4200 ---------(2)

Total  direct cost  for 2 servers (withoout  tax) per year,

= $ 2 \times 15 \times 8 \times 5 \times 50

= $ 60000

Total cost for helper ( without tax) per year,

= $ 4 \times 15 \times 5 \times \50

= $ 15000

Total cost for employees per year (without tax),

= $ (60000 +15000)  = $ 75000

Total cost per year for employees including tax,

$ \frac {(75000 \times (100 + 6.2 + 1.45)}{100}

= $ \frac {(75000 \times 107.65 }{100}

= $ 80737.5 -----------------------(3)

So,

total cost for running the restaurant (except food)

= (1) + (2) + (3) = $ (86400 + 4200 + 80737.5)

= $ 171337.5

Average total profit per customer,

= ( Average per customer payment - average cost of food per customer)

= $ (45.47 - 20.18)

= $ 25.29

So, total number of customer needed to break even,

= \frac {171337.5}{25.29}

\simeq   6775

How do I write a compound inequality?
ss7ja [257]

Answer:

it can either be written as x > -1 and x < 2 or as -1 < x < 2.

Step-by-step explanation:

The graph of a compound inequality with an "and" represents the intersection of the graph of the inequalities. A number is a solution to the compound inequality if the number is a solution to both inequalities. It can either be written as x > -1 and x < 2 or as -1 < x < 2.
