Elanso [62]

Answer:

a) 1/800 or 0.00125

b) i) 0.0013

ii) 0.001

c) 60%

Step-by-step explanation:

T = [tan(2×30)+1][2cos(30)-1] ÷ (y²-x²)

T = (tan60 + 1)(2cos30 - 1) ÷ (41² - 9²)

T = (sqrt(3) + 1)(sqrt(3) - 1) ÷ 1600

T = (3-1)/1600

T = 2/1600

T = 1/800

T = 0.00125

Error: 0.002 - 0.00125

0.00075

%error

0.00075/0.00125 × 100

60%

sleet_krkn [62]

Answer:

213 euros per month

Step-by-step explanation:

1dollar = 0.7306euros

thus $3,500 dollars can be found by a rule of three

dollar euro

1 ⇒ 0.7306

3500 ⇒ x

we find x as follows:

$x=\frac{0.7306*3500}{1} = 2,557.1$ euros

She will pay 2,557.1 euros per year.

Dividing between the 12 months of the year:

$\frac{2,557.1}{12}=213.1$

Rounding to the nearest whole euro she will pay 213 euros per month.
