Mathematics
1 answer:
n200080 [17]3 years ago
3 0

Answer:

3/4

Step-by-step explanation:

Let's say that r is the radius of the large circle or the diameter of the small circle.

Area of the big circle is \pi r^{2} .

Area of the small circle is \pi \frac{r}{2} ^{2} = \pi \frac{r^{2}}{4}.

The ratio of these 2 circles is 1/4 (calculation in the comments).

So the shaded part represent 1 - 1/4 = 3/4.

PLEASE HELP ASAP I WILL GIVE BRAINSLET TO THE CORRECT ANSWER!!!!!!!!!!
cestrela7 [59]

<u>Answer</u>:

Therefore has one solution.

<u>explanation</u>:

Given equations:

6x + y = -7

-24x -7y = 25

Make y the subject:

6x + y = -7

y = -7 - 6x ..............equation 1

-24x -7y = 25

-7y = 25 + 24x

y = (25 + 24x)/-7 ..........equation 2

Solve them simultaneously:

(25 + 24x)/-7 = -7 - 6x

25 + 24x = -7 (-7 - 6x)

25 + 24x = 49 + 42x

42x - 24x = 25- 42

18x = -24

x = -\frac{4}{3}

Then y is:

y = -7 - 6x

y = -7 - 6( -\frac{4}{3})

y = 1

Has one separate value of x and y: (  -\frac{4}{3} , 1 ); so it has one solution.
