Answer:

Step-by-step explanation:

This a not so simple ratio problem:

     MN is to LN as TN is to UN as MT is to LU

     MN/LN    =   TN/UN    =   MT/ LU         trying to find LU

     88 / (? + 32)   =  (88-56)/32   = 56/?

                            =     32 / 32   = 56 / ?        

                                   1  =  56 / ?  

                                   ?  = 56  

     88 / (56 +32)  = 1      This must be an Isosceles triangle and UT bisects

                                       LN and MN

elixir [45]

Answer:

According to the graph presented within the proposed interrogate, the answer to such is identified as ‘C’: 2, 3, 5, 5, 6, 7, 8, 10, 11.

Step-by-step explanation:

To evaluate for such a problem, a comprehension of the “Whisker” plots is obligated.

- The box geometric figure with the vertical line contained within represents the average of the numbers presented.

* In this peculiar case, 6 is acknowledged as the individual value responsible for the mean.

Thus far, browsing at such answer choices, we are obligated to appoint an answer where 6 is the standard deviation or the mean (where 6, and only 6, is found in the middle of the set of numbers provided).

The only answer choice in which certifies to all conditions thus far declared is disseminated as “C”.

*I hope this helps.

Step-by-step explanation:

<h3>Given GP with:</h3>
  • a1 = 10
  • r = -2
<h3>To find</h3>
  • S7
<h3>Solution</h3>

<u>Formula of sum:</u>

  • Sn = a1(r^n - 1)/(r - 1)

<u>Substitute values:</u>

  • S7 = 10((-2)^7 - 1)/(-2 - 1) = 10(- 128 - 1)/(-3) = 10*129/3 = 430

(t-5)=5(t-5)+8 I need the steps to solve also
Afina-wow [57]

Answer:

t = 3

Step-by-step explanation:

\tt (t-5)=5(t-5)+8

1) Expand

\tt t-5=5t-17

2) Add 5 to both sides

\tt t -5+5=5t-17+5

\tt t=5t-12

3) Subtract 5t from both sides

\tt t-5t=5t-12-5t

\tt -4t=-12

4) Divide both sides by -4

\tt \cfrac{-4t}{-4}=\cfrac{-12}{-4}

\tt t=3

Hope it helps! :)
