1) Tanθ= opposite/adjacent
θ=Tan-1(9/7)
θ=52.125 = 52 degrees

2) Cosθ= adjacent/hypothesis
θ=Cos-1(5/12)
θ=65.376 = 65 degrees

Aleks04 [339]

589 in base five is  4324_{5}.

Given number:

589

converting to 589_{5}.

⇒ 5|589

⇒ 5|117|4

⇒ 5|23|2

⇒ 5|4|3

⇒ 5|4|4

Now we write the last digit from last number to first that is,

= 4324_{5}.

Hence 589 in base five is  4324_{5}.

A fruit stand sells two varieties of strawberries: standard and deluxe. A box of standard strawberries sells for $4, and a box o
Andreas93 [3]

Answer:

75 boxes of standard varieties and 40 boxes of deluxe varieties.

Step-by-step explanation:

Let x be the number of standard variety and y be the number of the deluxe variety of the strawberry,

∵ Total number of strawberries = 115,

⇒ x + y = 115

⇒ x = 115 - y -----(1),

Total spending amount is $ 700, in which each standard variety costs $ 4 and deluxe variety costs $ 10,

⇒ 4x + 10y = 700 ----(2),

From equation (1),

4(115-y) + 10y = 700

460 - 4y + 10y = 700

460 + 6y = 700

6y = 240

⇒ y = 40

Again from equation (1),

x = 115 - 40 = 75

Hence, there are 75 boxes of standard varieties and 40 boxes of deluxe varieties.

A homeowner's backyard is a rectangle with width 18 yards long and length 16 yards long. They plan to put in a square pool with
Ugo [173]

Answer:

Step-by-step explanation:

Given the dimension of the  homeowner's backyard to be width 18 yards long and length 16 yards long, the area of the rectangular backyard id expreesed as;

Area of rectangle = Length * Width

Area of the rectangular backyard = 18yards * 16yards

Area of the rectangular backyard = 288yards²

If they plan to put in a square pool with side length 5 yards long in the backyard, the area of the pool = 5yd*5yd = 25yd²

The remaining area that will contain the tiles = Area of the rectangular backyard -  area of the pool

The remaining area that will contain the tiles = 288yd² - 25yd² = 263yd²

<em>Note that we cannot determine the amount of tiles they need to buy since we are not given the dimension of each tile to use</em>. The area needed for the tiles for the rest of the backyard is therefore 263yd².

Amount of tiles needed to buy can be expressed as 263/dimension of a tile.
