I = PRT

14,300 = (700)(0.0725)(t)
14,300 = 50.75(t)
14300/50.75 = t
281.77 = t    or    t = 281.77

hope this helps :)

Please help. I don’t understand and don’t know what do to.
Bingel [31]

Answer:

  72

Step-by-step explanation:

The triangles are said to be similar. (ΔNPQ ~ ΔRSQ) That means corresponding sides have the same ratio:

  NP/RS = NQ/RQ = PQ/SQ = 24/32 = 21/28 = 3/4

This ratio, or scale factor, also applies to the perimeters of the two triangles.

  perimeter NPQ / perimeter RSQ = 3/4

Using the given expressions for the perimeters, we have ...

  (7x +2)/(10x -4) = 3/4

We can solve this equation in the usual way to find the value of x. Then we can use that value to find the perimeter of ΔNPQ.

  4(7x +2) = 3(10x -4) . . . . . multiply both sides by 4(10x -4)

  28x +8 = 30x -12 . . . . . eliminate parentheses

  20 = 2x . . . . . . . . . . . add 12-28x to both sides

  10 = x . . . . . . . . . . . divide both sides by 10

The perimeter of ΔNPQ is ...

  7x +2 = 7(10) +2 = 72

The perimeter of triangle NPQ is 72 units.

Find square root of 144 by factorisation method​
Nady [450]

\huge \boxed{\mathbb{QUESTION} \downarrow}

  • Find square root of 144 by factorisation method.

\large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}

We can find the square root of 144 using the factorisation method. In this method, you need to factorise 144 first. Then, you'll get your answer in the form of prime factors. In this case, it's ⇨ 2 × 2 × 2 × 2 × 3 × 3.

__________________

To find the square root using factorisation, we need to group the same number in pairs. That is, 2 × 2 × 2 × 2 × 3 × 3 by grouping same numbers in pairs will become ⇨ (2, 2), (2, 2), (3, 3).

__________________

Now, you should take only 1 of the number from these groups. So, (2, 2), (2, 2), (3, 3) will change to ⇨ 2 × 2 × 3.

__________________

Finally, just multiply this set of numbers to find the square root of 144. 2 × 2 × 3 = 4 × 3 = \large\boxed{\underline{\bf \: 12}} ⇨ square root of 144.

  • The square root of 144 is <em><u>1</u></em><em><u>2</u></em><em><u>.</u></em>

At a local park there is a large compass painted on the sidewalk. Blaine starts at due north and walks 150° in a clockwise direc
Reika [66]

Yo sup??

the angle is in 3rd quadrant.

we can say that

sin(90+150)

=sin(180+60)

=-sin(60)

=-3^(1/2)/2

Hence the correct answer is option A

Hope this helps
