Hello!

You add the amount of sections have red or purple

2 + 2 = 4

Put this over the amount of sections

4 / 10 = 0.4

Multiply this by the amount of times he spins the spinner

180 * 0.4 = 72

The answer is about 72 times

Hope this helps!

The sphere has surface are of 900π m².

Step-by-step explanation:

Given,

Diameter = d = 30m

Radius = \frac{d}{2} =\frac{30}{2} = 15m

Surface area of sphere = 4\pi\ r^2

Surface\ area = 4*\pi *(15)^2\\Surface\ area = 4*\pi * 225\\Surface\ area= 990\pi

The sphere has surface are of 900π m².

How to solve -8-7x+5=4
Vlad1618 [11]
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation for example : -8-7x+-5(4)=0 . But the zero turned to -1 because a non zero constant never equals 0,but the problem doesn’t have a solution, but the answer is -1

A gardener uses 1/3 of a liter of water to water 2/7 of a garden.
Serjik [45]

the gardener would need (1 + 1/6) liters of water to water the whole garden.

<h3>How much water would the gardener need to water the whole garden?</h3>

Here we know that the gardener needs 1/3 of a liter of water to water 2/7 of a garden.

Then we have the relation:

1/3 L = 2/7 of a garden.

Now, we want to get a "1 garden" in the right side of the equation, then we can multiply both sides by (7/2), so we get:

(7/2)*(1/3) L = (7/2)*(2/7) of a garden

(7/6)L = 1 garden.

(1 + 1/6) L = 1 garden

This means that the gardener would need (1 + 1/6) liters of water to water the whole garden.
