Can someone please help me !
kipiarov [429]

Answer:

A = \frac{5}{6}

Step-by-step explanation:

From the number line attached in the figure,

Number of small parts from number 0 to 1 on the given number line = 6

A is the point which lies at 5th part from 0.

Each small part represents the fraction = \frac{1}{6}

Therefore, A represents the fraction = 5\times \frac{1}{6}

                                                             = \frac{5}{6}

So A = \frac{5}{6} will be the answer.

Mrs. Jackson earned a 500 bonus for signing a one-year contract to work as a nurse. Her salary is 22 per hour. If her first week
jekas [21]
Ok so your first step is to make this an equation
she gets paid x amount per hour and she works for 22 hours
so 22x plus her bonus
22x + 500 =1204
so now solve the equation
subtract both sides by 500
22x +500 =1204
-500 = -500
to get
22x = 704
now divide both sides by 22
x = 32

How much will it cost to pour a circular slab 18 ft in diameter by 3 in. For a patio if the concrete costs $40.00 per cubic yard
sasho [114]
A circular concrete slab is a cylinder. Vol = pi%2Ar%5E2%2Ah
in this cylinder:
r = 18%2F2 = 9 ft
h = 3%2F12 = .25 ft
:


Find the volume in cu/ft:
V = pi%2A9%5E2%2A.25
V = 63.61725 cu/ft
:
Change to cubic yds; (1 cu/yd = 27 cu/ft) and multiply by $40:
Cost = 63.61725%2F27 * 40
Cost = $94.25


In practical terms , they may require you to buy 3 cu/yds , which is $120
