Answer:

Step-by-step explanation:

Let's recall that the interior angles of a triangle always add up to 180 degrees.

Upon saying that, we have:

102 + 39 + x = 180

x = 180 - 102 - 39

x = 39

<u>The value of x is 39 degrees</u>

Answer:

Step-by-step explanation:

$-2(5y-5)-3y\leq -7y+22$

Expand parentheses:

$-10y+10-3y\leq -7y+22$

Move all y's to one side and numbers to the other:

$-6y\leq 12$

Divide both sides by -6. Since you are dividing both sides by a negative number, you need to flip the comparator:

$y\geq -2$

Hope this helps!

To build 12 birdhouses, Felipe needs 5 1/4 meters of wood. He was asked to make 4 1/2 times the number of birdhouses he usually

Dimas [21]

Using proportions, it is found that Felipe needs 23.625 meters of wood to make that many birdhouses.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

To make an amount, he needs 5 1/4 meters = 5.25 meters. How many meters he needs to make 4 1/2 = 4.5 times the amount?

5.25 x 4.5 = 23.625 meters.

Felipe needs 23.625 meters of wood to make that many birdhouses.

In 1990, California switched from a 6/49 lottery to a 6/53 lottery. Later, the state switched again to a 6/51 lottery. (a) Find

zalisa [80]

Answer:

(a) 9.9321*10^{-11}

(b) 6.0498*10^{-11}

(d) 1.6417 times more probable

Step-by-step explanation:

(a) The probability of winning a 6/49 lottery is given by:

$P = \frac{1}{49*48*47*46*45*44} =9.9321*10^{-11}$

(b) The probability of winning a 6/53 lottery is given by:

$P = \frac{1}{53*52*51*50*49*48} =6.0498*10^{-11}$

(c) The probability of winning a 6/51 lottery is given by:

$P = \frac{1}{51*50*49*48*47*46} =7.7120^{-11}$

(d) The ratio between the probabilities of winning the 6/49 lottery and winning the 6/53 lottery is:

$r=\frac{9.9321*10^{-11}}{6.0498^{-11}}\\r=1.6417$

It is 1.6417 times more probable.
