It takes 3 1/3 kilometers of thread to make 3 1/2 boxes of shirts. How many kilometers of thread will it take to make 6 boxes?
Julli [10]

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

2. A guy wire for a tree is 20 ft. long, making a 21o angle with the ground. How far is the base of the tree from a stake anchor
Alenkasestr [34]

Answer:

the base of the tree from a stake anchoring the wire is 18.7 ft long

Step-by-step explanation:

A guy wire for a tree is 20 ft. long, making a 21 degree angle with the ground.

It forms a right angle triangle. the hypotenuse of the triangle is 20 ft

The adjacent side of the given angle 21 degree is the base of the tree from a stake

Let x be the base length

cos(theta)=\frac{adjacent}{hypotenuse}

cos(21)=\frac{x}{20}

20cos(21)=x

x=18.7

the base of the tree from a stake anchoring the wire is 18.7 ft long
