Your answer is D){28, 42, 56, 70, 84}

To answer this question you just have to make sure the amount he pays is a multiple of 7.If you know you times table then this should be easy

Times table of 7:

7,14,21,28,35,42,49,55,63,70,77,84.

Now you just need to find an answer choice who has these numbers.Lets check it out!

A) 11 isn't a multiple of 7

B) 56 isn't a multiple of 7

C) None of these are multiples of 7 except 7 so this is also incorrect

D) This is correct because they are all multiples of 7

Hope this makes sense.

$\bf 6-5x+6=4\implies -5x+12=4\implies \stackrel{\textit{adding 5x to both sides}}{12=4+5x}\\\\\\\stackrel{\textit{subtracting 4 to both}}{8=5x}\implies \cfrac{8}{5}=x\implies 1\frac{3}{5}=x$

Problem A park has a large circle painted in the middle of the playground area. The circle is divided into 444 equal sections, a

Vladimir79 [104]

Answer:

25 $\pi\ m^2$

Step-by-step explanation:

Given that:

A large circle in the park has its middle part painted.

The circle is divided in 4 equal parts.

Radius of the circle = 10 meters

To find:

Area of each section of the circle, $A$ = ?

Solution:

Here, we need to find the area of the bigger circle first and then need to divide it into 4 equal parts to find out the answer.

First of all, let us have a look at the formula for area of a circle with given radius $r$ :

$Area = \pi r^2$

Here, $r = 10 m$

Putting the value in the above formula, we get:

So, area = $\pi 10^2 = 100\pi\ m^2$

Now, there are 4 equal parts of the circle, therefore area of each section will be equal.

Area of each section of the circle:

$\dfrac{100\pi}{4} = \bold{25 \pi}\ m^2$
