If QRST is a rectangle with QT=50 and RS=4x+8, find x

Alenkinab [10]

<span>If QRST is a rectangle with QT = 50 and RS = 4x + 8, find x.
.
QT = RS (opposite sides of a rectangle are equal)

50 = 4x + 8
42 = 4x

A bag contains tiles with the letters p -r-o-b-a-b-i-l-i-t-y Tyler chooses a tile without looking and doesn't replace it he choo

ipn [44]

Answer:

$\frac{1}{55}$

Step-by-step explanation:

Total number of tiles: 11 (obtained from counting the letters in probability)

Probability of picking the letter "i" the first time:

There are 2 letter "i's", and 11 total options, so the probability of picking an "i" is:

$\frac{2}{11}$

Probability of picking the letter "i" the second time:

We now have one less letter in the bag, as the first letter "i" was not replaced.

This means we now only have 1 letter "i", and 10 total options, so the probability of picking the last "i" is:

$\frac{1}{10}$

When you have two probabilities that are dependant on each other, you multiply them to get the probability of one, given that the other has happened.

Total probability:

$\frac{2}{11}*\frac{1}{10} = \frac{2}{110}$

Simplify by dividing by 2:

$\frac{1}{55}$

Solve for X answer as a whole number

stepladder [879]

Step-by-step explanation:

${a}^{2} = {4}^{2} + {2}^{2} \\ {a}^{2} = 16 + 4 \\ {a}^{2} = 20 \\ a= \sqrt{20} \\ {x}^{2} = {( \sqrt{20} )}^{2} + {3}^{2} \\ {x}^{2} = 20 + 9 \\ {x}^{2} = 29 \\ x = 5.385$

as a whole number = 5
