Write each as the sum of two terms in the form t_n,r. t_5,3 , t_11,2 , t_15,13
Anarel [89]

The sum of two terms are:

  • t₅, ₃ = 8
  • t₁₁, ₂ = 13
  • t₁₅,₁₃ = 28.

<h3>What is the sum about?</h3>

The sum of two numbers is one that tells you to find the sum of two or more numbers, and as such, you have to add the numbers altogether.

t₅, ₃ =  5 + 3

= 8

t₁₁, ₂ = 11 + 2

= 13

t₁₅,₁₃ =  15 + 13

= 28.

Hence the correct sum of two terms are:

  • t₅, ₃ = 8
  • t₁₁, ₂ = 13
  • t₁₅,₁₃ = 28.

Help me please, its mathwatch
mars1129 [50]

Answer:

<h2>60 cm^2</h2>

Solution,

Let ,

a = 13

b = 13

c= 10

then,

s = a + b + c /2

= 13 + 13 + 10 / 2

= 36/2

= 18

Now,

Area of triangle:

\sqrt{s(s - a)(s - b)(s - c)}

\sqrt{18(18 - 13)(18 - 13)(18 - 10)}

\sqrt{18 \times 5 \times 5 \times 8}

\sqrt{3600}

60 \:  {cm}^{2}

Hope this helps ....

Good luck on your assignment...

Two consecutive whole number that lies between the square root of 38
Semenov [28]
√38

Let's name all the squares.
1² = 1 x 1 = 1
2² = 2 x 2 = 4
3² = 3 x 3 = 9
4² = 4 x 4 = 16
5² = 5 x 5 = 25
6² = 6 x 6 = 36
7² = 7 x 7 = 49
8² = 8 x 8 = 64

Okay that's far enough. Now we look for which numbers 38 is in between.
That would be 36 and 49.
But it's asking for where the square root of 38 is, so √36 and √49 ⇒ 6 and 7.

Found the value of t needed to make the equation shown true.<br><br> 25t = 12.5
liberstina [14]

Answer:

0.5

Step-by-step explanation:

To find the value of t, we need to get t by itself.

25t=12.5

25 is being multiplied by t. To undo this, divide both sides by 25, since division is the opposite of multiplication. This will cancel out the 25, and leave t by itself.

25t/25=12.5/25

t=0.5

So, the value of t that makes the equation true is 0.5
