Well x=1 always unless it tells you other wise so 1+0.5 would equal 1.5 and so after that you keep adding so 1.5 + 0.5 equal 2 so you keep taking the previous answer and adding 0.5 to it

The world brand of rivet placement is 11209 rivets in 9 hours and belongs to J. Mair of Ireland. If another person places 11209

Ilya [14]

Answer:

4.74 hours

Step-by-step explanation:

Given that both person have to place same number of rivets that is

11209

first person take 9 hours to complete the work

hence 1 hour work of 1st person is $\frac{1}{9}$ of total work

second person takes 10 hours to complete the same work

hence 1 hour work of 2nd person is $\frac{1}{10}$

Now if both work together then

1 hour work of both person = $\frac{1}{9} +\frac{1}{10}$ = $\frac{19}{90}$

thus working together they need $\frac{90}{19}$ hours = 4.74 hours to complete the whole work which is placing 11209 rivets

Please Help! (Math)(tanβ)

sertanlavr [38]

Answer:

<u>Find the missing side first.</u>

x = $\sqrt{12^2 - 7^2} = \sqrt{144 - 49} = \sqrt{ 95}$

1) tangent = opposite leg / adjacent leg

tanβ = √95/7
Correct choice is B

2) sine = opposite leg / hypotenuse

sinβ = √95/12
Correct choice is D
