Allison ran 3/8 km (0.375 km) in 3 minutes.

Set up a proportion to find how long it takes for her to run 1 km

\frac{0.375\textrm{km}}{3 \textrm{min}} = \frac{1\textrm{km}}{x \textrm{min}}

Cross multiply to get:

3 = 0.375x

Solve:

x = \frac{3}{0.375}

x = 8 minutes

Each day a small business owner sells 200 pizza slices for $1.50 per slice and 85 sandwiches at $3.50 each. Business exspenses c
notsponge [240]

Answer:

The owner's profit for a ten-day period is $4675

Step-by-step explanation:

Each day a small business owner sells 200 pizza slices for $1.50 per slice and 85 sandwiches at $3.50 each.

Let's find the revenue.

Revenue = 200($1.50) + 85($3.50)

= $300 + $297.50

Revenue per day = $597.50

Revenue for 10 days = 10($597.50) = $5975

Business expenses per day = $130

Business expenses for 10 days = 10($130) = $1300

Now let's find the profit.

Profit for 10 days = Revenue - Expense

= $5975 - $1300

= $4675

So the owner's profit for a ten-day period is $4675

The first five terms of a sequence are
Elena L [17]

Answer:

(a) 7 + 3( n - 1 )

(b) 1006

Step-by-step explanation:

ARITHMETIC SEQUENCE.

The number of term of an Arithmetic progression has the formular :

nth term = a + ( n - 1 ) d

a = 7

d = 10 - 7 = 3

nth term = 7 + ( n - 1 ) 3

= 7 + 3n - 3

= 7 + 3( n - 1 )

Therefore,

the nth term of the sequence

= 7 + 3( n - 1 )

(b) For the 1000th term

= 7 + 3 ( 1000-1 )

= 7 + ( 999 )

7 + 999 = 1006

Therefore,

the 1000th term = 1006
