62 x 1= 1

and that was the bills, add them together, you get 529.

then multiply the amount of what the change is by the amount of change there is so, 13 x 25= 325 3 x 5= 15 and 93 x 1= 93.

If f(1)=3 and f(n)=-2f(n-1)+1,then f(5)=

Drupady [299]

F(5) = - 2f(4) + 1
f(4) = -2f(3) + 1
f(3) = -2f(2) + 1
f(2) = -2f(1) + 1
Therefore:
f(2) = -2(3) + 1 = -5
f(3) = -2(-5) + 1 = 11
f(4) = -2(11) + 1 = -21
Therefore f(5) = -2(-21) + 1 = 43

Sally begins hiking at an elevation of 224 feet. Then, she descends 131 feet and climbs 67 feet higher than her current position

Deffense [45]

Answer:

-3

Three feet below the initial elevation

Step-by-step explanation:

The initial elevation is 224 feet.

We take descent to be negative and ascent to be positive.

The numerical addition expression is

$224+-131+67+-163$

We simplify this to obtain:

$224-131+67-163=-3$

The negative sign means Sally is 3 feet below his initial elevation

Danny's Bike Shop sells a certain model of racing bike for $550. The same bike can be bought at a competing shop for 7 percent l

AleksAgata [21]

Answer:

$511.5

Step-by-step explanation:

Given: Selling price of bike at Danny´s shop is $550

Bike is sold 7% less at competitor´s shop.

Lets find the discounted amount at Danny´s competitor shop.

∴ $\frac{7}{100} \times 550 = \$ 38.5$

Now, finding the cost of bike at Danny´s competitor.

Cost of bike at Danny´competitor= $(\textrm{Price at dannys shop - discount provided by competitor})$

Cost of bike at Danny´s competitor= $550-38.5= \$511.5$

∴ Cost of bike at Danny´s competitor is $511.5.

It takes a hose 2 minutes to fill a rectangular aquarium 8 inches long, 10 inches wide, and 14 inches tall. How long will it tak

kari74 [83]

Answer:

66 minutes, or 1 hour and 6 minutes.

Step-by-step explanation:

let us first do the rectangular aquarium:

8 x 10 = 80

80 x 14 = 1120

now the second box

23 x 25 = 575

575 x 33 = 18975

we can divide the boxes volume:

18975/575 = 33

so all we have to do is times 33 by 2 which equals:

66 minutes, or 1 hour and 6 minutes.
