Answer:
Percentage = 14.2%
Step-by-step explanation:
<u>Given the following data;</u>
Cost of plane ticket = £588
Airport tax = $130
£1 = $1.34
To find the percentage of the total cost spent on airport tax;
First of all, we would convert the ticket cost in pounds (£) to dollars ($).
Cost of plane ticket = £588 to $ = 588 * 1.34 = $787. 92
Total cost = Cost of plane ticket + Airport tax
Total cost = 787. 92 + 130
Total cost = $917.92
<em>Percentage cost = 14.16 to 1 d.p = 14.2%</em>
<em>Therefore, the percentage of the total cost spent on airport tax by Rimo is 14.2 percent. </em>
The length of guy wire needed to make an angle of 30° with the ground is 310 feet. The angle between the end of the shadow and the vertical side of the building is 23°
<h3>What is
trigonometric ratio?</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
a) Let l represent the length of the guy wire.
sin(30) = (170 - 15) / l
l = 310 feet
b) Let Ф represent the angle, hence:
tanФ = 100/230
Ф = 23°
The length of guy wire needed to make an angle of 30° with the ground is 310 feet. The angle between the end of the shadow and the vertical side of the building is 23°

Theresa would have to pay $31.96 for 4 yards of fabric.
Answer:
B
Step-by-step explanation:
the six(6) muffins plus the $3 she saved
To find the difference of the given expression, first step is to get rid of parenthesis. So, distribute negative sign to each terms of the second parenthesis. Hence,
(9x² + 10x + 4) - (9x² + 5x - 1)
= 9x² + 10x + 4 - 9x² - 5x + 1.
= (9x² - 9x²) +(10x - 5x) + (4 + 1) Group the like terms.
= 0 + 5x + 5 Combine the like terms.
= 5x + 5.
So, first choice is correct.
Hope this helps you!
