Answer:

Option B is correct.

Step-by-step explanation:

Let's first turn 7:6 into a fraction:

=> 7:6 = 7/6

Now, let's simplify all the options to see which one is the correct answer.

Option A:

=> 14:18
=> 14/18
=> 7/9
=> 7/9 ≠ 7/6

Therefore, Option A is incorrect.

Option B:

=> 21:18
=> 21/18
=> 7/6
=> 7/6 = 7/6

Therefore, Option B is correct.

Option C:

=> 21:12
=> 21/12
=> 7/4
=> 7/4 ≠ 7/6

Therefore, Option C is incorrect.

Option D:

=> 18:14
=> 18/14
=> 9/7
=> 9/7 ≠ 7/6

Therefore, Option D is incorrect.

We can conclude that Option B is correct.

The following is an equilateral triangle. Solve for y.

GuDViN [60]

Answer:

y = 68 degrees

Step-by-step explanation:

Here, we want to solve for an equilateral triangle with the internal angle measurement being y-8

If one of the angles is y-8, then the rest are y-8 too

mathematically, by adding all , we have a total of 180

Thus;

3(y-8) = 180

y-8 = 180/3

y-8 = 60

y = 60+8

y = 68 degrees

Simplify √(x^2-10x+25) if -5≤x<5

romanna [79]

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's simplify ~

$\qquad \sf \dashrightarrow \: \sqrt{ {x}^{2} - 10x + 25 }$

$\qquad \sf \dashrightarrow \: \sqrt{ {x}^{2} - 5x - 5x + 25 }$

$\qquad \sf \dashrightarrow \: \sqrt{ {x}^{} (x- 5) - 5(x - 5) }$

$\qquad \sf \dashrightarrow \: \sqrt{ (x- 5) (x - 5) }$

$\qquad \sf \dashrightarrow \: \sqrt{ (x- 5) {}^{2} }$

$\qquad \sf \dashrightarrow \: (x- 5)$

value x lies between :

$\qquad \sf \dashrightarrow \: - 5 \leqslant x \leqslant 5$

if the value of x is taken -5

$\qquad \sf \dashrightarrow \: - 5 - 5$

$\qquad \sf \dashrightarrow \: - 10$

if value of x is taken as 5

$\qquad \sf \dashrightarrow \:5 - 5$

$\qquad \sf \dashrightarrow \:0$

So, the possible values of the required expression lies between ~

$\qquad \sf \dashrightarrow \: - 10 \leqslant \sqrt{ {x}^{2} - 10x + 25 } < 0$

I hope you understood the whole procedure. let me know if you have any doubts in given steps ~

I’m really confused on how to solve this can someone please help me fast!!!!

beks73 [17]

Answer:

130.24

Step-by-step explanation:

8*10+3.14*4^2=

80+50.24=130.24 ft^2

Cut the shape into a semi-circle and rectangle (with length 10 and width 8).

You'll find the radius of the semi-circle is 4.

The area of the rectangle is 80.

Then use the pir^2 formula but replace pi with 3.14

3.14 multiplied by radius 4 squared is 50.24

50.24 plus 80 is 130.24 ft squared.
