Scuba diving in the reef will cost $120 Australian dollars I have $118 US dollars in my pocket use the equation y = 1.03x where

Lana71 [14]

Answer:

Yes,he can go to scuba diving

Step-by-step explanation:

Given the has $118 american dollars

Also given that the relation betweeen the australian and american currency is y = 1.03x where y is the amount in australian currency and x is the amount in the american currency.

Now we have x= 118.

$y=1.03\times118=121.54$

So the guy has $121.54 Australian dollars and the scuba diving is $120 Australian dollars.Since it cost's less he can afford the scuba diving.

The diagonals of a quadrilateral QRST intersect at P(-1,3). QRST has vertices at Q(3,6) and R(-4,5). What must be the coordinate

erica [24]

S = (-5,0)

T = (2,1)

Step-by-step explanation:

Step 1 :

Given

Q = (3,6) and R = (-4,5). P = (-1,3)

Let S be (a,b) and T be (c,d)

The diagonals of a parallelogram bisect each other. so in order to ensure that QRST is a parallelogram, P must be the mid point of the diagonals QS and RT.

Step 2 :

P is the midpoint of QS

So we have (3+a) ÷ 2 = -1 and (6 + b) ÷ 2 = 3

=> 3 + a = -2 and 6 + b = 6

=> a = -5 and b =0

So S should be (-5,0)

Step 3 :

P is the midpoint of RT

So we have (-4+c) ÷ 2 = -1 and (5 + d) ÷ 2 = 3

=> -4+ c = -2 and 5 + d = 6

=> c = 2 and d =1

So T should be (2,1)

Step 4 :

Answer :

S = (-5,0)

T = (2,1)

A square has a side length 9cm . What is its area?

Leya [2.2K]

Answer:

81 cm^2

Step-by-step explanation:

1. The area of a square is s^2, where s = length of side. In this case, s = 9.

$9^2$
$9 * 9$
$81$

Therefore, the area is 81 cm^2.

HELP me with These questions 2

LUCKY_DIMON [66]

Answer: 4

Step-by-step explanation:

A = $\frac{1}{2}$ r²θ

50 = $\frac{1}{2}$ (5)²θ

100 = (5)²θ

100 = (25)θ

4 = θ

********************************************************************************

Answer: 1570.80 cm²

Step-by-step explanation:

A = $\frac{1}{2}$ r²θ

A = $\frac{1}{2}$ (100)² $(\frac{\pi}{10})$

A = 500π

A = 1570.80

********************************************************************************

Answer: 19.63 m²

Step-by-step explanation:

A = $\frac{1}{2}$ r²θ

= $\frac{1}{2}$ (5)² $(\frac{\pi} {2})$

= $\frac{25\pi} {4}$

= 19.63

********************************************************************************

Answer: 15°

Step-by-step explanation:

$\frac{\pi }{180} = \frac{\pi} {12x}$

180 = 12x

15 = x

********************************************************************************

Answer: A

Step-by-step explanation:

Quadrant I: 0° - 90°

Quadrant II: 90° - 180°

Quadrant III: 180° - 270°

Quadrant IV: 270° - 360°

255° is in Quadrant III
