Answer:

Step-by-step explanation:

Since AB ≅ BD that means they equal the same

2x + 3 = 5x - 6

First: subtract 2x from both sides thus giving you

3 = 3x - 6

Second: add six to both sides, divide by three and simplify

9 = 3x

$\frac{9}{3}$ = $\frac{3x}{3}$

x = 3

Lastly: substitute values of x and simplify

AB = 2(3) + 3 = 9

BD = 5(3) - 6 = 9

9 + 9 = 18

AD = 18

The measure of segment AB is 2x-3 and the measure of segment BD is 5x-6.
If you want to find the measure of segment AD you have to add up AB and BD

So $2x-3+5x-6$ , combine like terms 2x+5x equals 7x and -3-6 equals -9, so the measure of segment AD is $7x-9$

What is the logarithmic formula 10000= 625/8*2^t ?

Answer:

log(128) = t·log(2)

Step-by-step explanation:

You can take logarithms the way the formula is, or you can simplify it first.

log(10000) = log(625) -log(8) +t·log(2)

<u>Simplified</u>

8·10000/625 = 2^t . . . . . multiply by 8/625

128 = 2^t

log(128) = t·log(2)

_____

Solution:

t = log(128)/log(2) = 7

So far, this is shaping up to be a very interesting and engaging exercise. Now, what do you want done with the model ? To put it in other words, what is the question ? ? (Other than the fact that no real flight can fit this model.)

Camryn practices the trumpet every 11th day and the flute every 3rd day. Camryn practiced both the trumpet and the flute today.

QveST [7]

Answer: 33 days.

Step-by-step explanation:

Given :- Camryn practices the trumpet every 11th day and the flute every 3rd day.

Camryn practiced both the trumpet and the flute today.

To find the number of days until Camryn practices the trumpet and flute again in the same day, we need to find the least common multiple (L.C.M.) of 11 and 3.

As they both are co-prime numbers thus its L.C.M.= 11×3=33

Therefore, Camryn practices the trumpet and flute again in the same day after 33 days.
