Answer:

k=16

Step-by-step explanation:

k/4-1=3

first add 1 to both sides of equation

k/4-1+1=3+1

k/4=4

A company that offers tubing trips down a river rents tubes for a person to use for $20 and “cooler” tubes to carry food and wat
Licemer1 [7]

<u>Answer:</u>

The number of each type of tube does the group rent is 11 tubes for person and 4 “cooler” tubes to carry food and water  

<u>Explanation:</u>

The rents for tubes for a person to use = $20

The rents for “cooler” tubes to carry food and water = $12.50.

The rent for a total of 15 tubes = $270

11 tubes whose rent cost  $20 =11 \times 20

                                                   = 220

4 “cooler” tubes rent cost  $12.50 =4 \times 12.5

                                                   = 50

Therefore for 15 tubes = 11 +4= 15

                            cost = 220 + 50

                                    =270                                                  

The number of each type of tube does the group rent is 11 tubes for person and 4 “cooler” tubes to carry food and water

Help please. Having some trouble with this question
xeze [42]

Answer:

The answer to your question is 55 ft

Step-by-step explanation:

Data

Person's height = 5 ft

Person's shadow = 10 ft

Tree's height = ?

Tree's shadow = 110 ft

- Use the Thales' theorem to solve this problem

 Person's height / Person's shadow = Tree's height / Tree's shadow

- Substitution

                     5 / 10 = x / 110

-Solve for x

                     x = 5 (110) / 10

-Simplification

                     x = 550 / 10

-Result

                     x = 55 ft

-Conclusion

The tree is 55 ft height

The central angle of a circle measures 108 degrees and intercepts an arc of 6pi inches.
damaskus [11]

An arc is a part of the circumference of a circle and the angles that subtend the arcs are proportional to the length of the arc.

So, you basically have two arcs to compare: a 10cm arc and a 60cm arc. But the 60cm arc also happens to be the circumference in this case, so you know that the angle that subtends that arc is 360 degrees (the whole circle). The 10cm arc is 1/6 of the whole circumference so the angle is going to be 1/6 of 360 degrees, which is <span>60 degrees.</span>
