sergiy2304 [10]

Answer:

$39.33 (rounded to nearest cent)

Step-by-step explanation:

Cost of shirt normally = $65

Cost of shirt for 3 days = $\frac{100-45}{100}$ × $65

= $\frac{55}{100}$ × $65

= $35.75

Cost of shirt on 4th day = $\frac{100+10}{100}$ × $35.75

= $\frac{110}{100}$ × $35.75

= $39.33 (rounded to nearest cent)

Find the value of the length x rounded to 1 DP.

ivanzaharov [21]

Answer:

x = 13.6 cm

Step-by-step explanation:

part A:

using tan rule:

$tan(x) = \frac{opposite}{adjacent}$

$tan(39) = \frac{6}{adjacent}$

$adjacent = \frac{6}{tan(39)}$

$adjacent = 7.41$

part B:

using tan rule:

$tan(x) = \frac{opposite}{adjacent}$

$tan(44) = \frac{6}{adjacent}$

$adjacent = 6.213$

Total length of x:

part A + part B

$7.41 + 6.213$

$13.6$ cm
