Answer: y = -2/5x +8

Step-by-step explanation:

  • 5y = -2x + 40 (subtract 2x from both sides)
  • y = -2/5x + 40/5 (divide both sides by 5)
  • y = -2/5x + 8 (simplify)

A shoemaker makes three new souls every four minutes another shoemaker made to souls every three minutes what was the difference
yKpoI14uk [10]

Answer:

<h2> 15 souls </h2>

Step-by-step explanation:

If a shoemaker makes three new souls every four minutes, the number of soles he will make in an hour can expressed as shown;

3 souls = 4 minutes

x souls = 1hour (60 minutes)

Cross multiplying to get the number of souls;

4 * x = 3 * 60

4x = 180

x = 180/4

x = 45souls

Hence the number of souls made by this shoemaker in an hour is 45 souls.

Similarly, If another shoemaker makes two new souls every three minutes, the number of soles he will make in an hour can expressed as shown;

2 souls = 3 minutes

y souls = 1hour (60 minutes)

Cross multiplying to get the number of souls;

3 * y = 2 * 60

3y = 120

y = 120/4

y = 30souls

Therefore the number of souls made by this shoemaker in an hour is 30 souls.

The difference in the number souls they made in an hour will be x - y where x = 45 souls and y = 30 souls.

x - y = 45 - 30

The difference is equal to 15 souls

The area of a ferris wheel is about 154 square meters. Which of the following is closest to the length of one of the spokes? [As
babunello [35]

Answer:

The length of one of the spoke is 7 m

Option C is correct answer.

Step-by-step explanation:

Area of Ferris Wheel = 154 square meters.

We need to find  the length of one of the spokes.

We are given: Assume  the spokes go from the centre to the edge of the Ferris wheel.

So, We are given area of circle and we need to find radius of circle.

The formula used is: Area\:of\:circle=\pi \:r^2

Putting values and finding radius

Area\:of\:circle=\pi \:r^2\\154=3.14\:r^2\\r^2=\frac{154}{3.14}\\r^2=49\\Taking\:square\;root\\\sqrt{r^2}=\sqrt{49}\\r=7\:m

So, Radius of circle = 7 m

The length of one of the spoke is 7 m

Option C is correct answer.
