Answer:

10 z's

Step-by-step explanation:

5x's=4y's = 15x's=12y's

12y's = 5z's

15x's = 12y's = 5z's so 15x's = 5z's

multiply both by 2

30x's = 10 z's

a taxi ride costs 40 dollars for the first 500 meters and each additional 300 meters (or a fraction thereof) adds $3.50 to the f
Colt1911 [192]

Answer:

$ 71.5

Step-by-step explanation:

firstly kilometer to meters

<em>1 km = 1000 m </em>

therefore 3 km = 3000m

for the first 500 = $40

hence deduct the 500 from 3000m

3000 - 500 = 2500

now find out how many 300m go into 2500

2500 / 300 = 8.33

which is rounded up to 9

therefore the total amount is :

40 + 9 * 3.5

<u>= $71.5</u>

|3x-7|-7=x solve the equation for all values of x
romanna [79]

The solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.

<h3>What are the solutions to the given equation?</h3>

Given the equation in question;

|3x-7| - 7 = x

First, add 7 to both sides.

|3x-7| - 7 + 7 = x + 7

|3x-7|  = x + 7

Next, remove the absolute value term, this creates a ± on the right side of the question.

|3x-7|  = x + 7

3x-7  = ±( x + 7 )

The complete solution is the result of both the negative and positive portions of the solution.

For the first solution, use the positive of ±.

3x-7  = ( x + 7 )

3x - 7  =  x + 7  

3x - x = 7 + 7

2x = 14

x - 14/2

x = 7

For the second solution, use the negative of ±.

3x-7  = -( x + 7 )

3x-7  = -x - 7

3x + x = -7 + 7

4x = 0

x = 0/4

x = 0

Therefore, the solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.

A cylindrical container is used to hold drinking water on the sidelines for a football team. The maximum capacity of the contain
wlad13 [49]
To solve this we are going to use the formula for the volume of a cylinder: V= \pi r^2h
where
V is the volume of the cylinder in cube centimeters 
r is the radius of the cylinder in centimeters 
h is the height of the cylinder in centimeters 

We know for the problem that volume of our cylinder is 26,460 mL. Since 1 mL =1cm^3, the volume of our cylinder is 26460cm^3. We also know for our problem that the height of our cylinder is 60 cm, so h=60. Lets replace those values in our formula and solve for r:
V= \pi r^2h
26460= \pi r^2(60)
26460=60 \pi r^2
r^2= \frac{26460}{60 \pi }
r^2= \frac{441}{ \pi }
r= \sqrt{ \frac{441}{ \pi } }
r= \frac{21}{ \sqrt{ \pi } }
r=11.8

We can conclude that the radius of the football team's <span>cylindrical container is 11.8 cm</span>
