Answer:

5 5/7 km

Step-by-step explanation:

We assume the length of thread is proportional to the number of boxes of shirts. If L is the thread length required, then that assumption means

... L/(6 boxes) = (3 1/3 km)/(3 1/2 boxes)

Multiplying the equation by (6 boxes), we get

... L = (3 1/3 km)(6/(3 1/2)) = (10/3 km)(6/(7/2))

... = (10/3 km)(12/7) = 40/7 km = 5 5/7 km

For f(x) = 2x + 1 and g(x) = x2 - 7, find (f + g)(x).​
horsena [70]

Answer:

(f+g)(x)=x²+2x-6

Step-by-step explanation:

(f+g)(x)=2x+1+x²-7

collect like terms

(f+g)(x)=x²+2x+1-7

according to mathematics x² is not a like term of 2x so don't add the them

(f+g)(x)= x²+2x-6

Find the missing side. Round it to the nearest tenth
Klio2033 [76]
Answer: 53.6

Explanation:

When given a side and its opposing angle and another angle, to find its opposing side you may use the sine rule.

sin(Angle)/opposing side = sin(Angle)/opposing side

Applying this formula will give us the following:

1) sin90/x = sin66/49
2) 1/x = 0.01864
3) 1/0.01864 = x
4) x ≈ 53.6

Hope this helps, brainliest would be appreciated :)
