Answer:
£85.55.
Step-by-step explanation:
The total additions is (0.2 + 0.1) = 0.3x where x is the cost excluding VAT and service, then:
x + 0.3x = 111.21
x = 111.21 / 1.3
= £85.55.
Answer:
Step-by-step explanation:
it's important to mention this only works for right triangles. Or in other words a triangle that has a 90 degree angle. the two sides connected to that right angle are called legs, while the one side not touching it is the hypotenuse, which is what we're looking for.
we are going to use the Pythagorean theorem. if we label one leg a and the other as b, it doesn't matter which one is which, and the hypotenuse as c we have the relation
so let's plug in.
let me know if you need any more help.
Answer:
A. <u>4</u> trucks will make $80 because 4 × 20 = 80, so they need to wash <u>38</u> cars to make the other $380 because 38 × 10 = 380.
($80 + $380 = $460)
B. <u>15</u> trucks will make $300 because
15 × 20 = 300, so they need to wash <u>16</u> cars to make the other $160 because 16 × 10 = 160. ($300 + $160 = $460)
C. <u>21</u> trucks will make $420 because
21 × 20 = 420, so they need to wash <u>4</u> cars to make the other $40 because 4 × 10 = 40.
($420 + $40 = $460)
D. <u>27</u> trucks will make $540, so they won't have to wash any cars because they would have already exceeded their goal of $460.
Not sure what to do for letter E. Sorry. I hope the rest makes sense though :)
