Answer:

Step-by-step explanation:

Evaluate the fractions inside the absolute value

2 $\frac{5}{6}$ + $\frac{7}{4}$ ( change mixed number to improper fraction )

= $\frac{17}{6}$ + $\frac{7}{4}$ ( the LCM of 6 and 4 is 12 ) , then

= $\frac{17(2)}{6(2)}$ + $\frac{7(3)}{4(3)}$

= $\frac{34}{12}$ + $\frac{21}{12}$ ( add the numerators, leaving the common denominator )

= $\frac{55}{12}$

= 4 $\frac{7}{12}$ → D

Find the value of X.

Tju [1.3M]

Answer:-

x=110 degree

Step-by-step explanation:

It's quadrilateral so it's total sum degree is 360

then 40+82+128+x=360

360-(128+82+40)=X

x=360-250

x=110 degree

Is 890,353 mL bigger than 89 L 353mL

Gemiola [76]

Yes, because 89L = 89,000ml. So 89L 353mL = 89,353mL. Thus, 890,353mL is greater.

John and Martha are contemplating having children, but John’s brother has galactosemia (an autosomal recessive disease) and Mart

Rina8888 [55]

<h2>Answer:</h2>

$Probability=\frac{1}{24}$

<h2>Step-by-step explanation:</h2>

As the question states,

John's brother has Galactosemia which states that his parents were both the carriers.

Therefore, the chances for the John to have the disease is = 2/3

Now,

Martha's great-grandmother also had the disease that means her children definitely carried the disease means probability of 1.

Now, one of those children married with a person.

So,

Probability for the child to have disease will be = 1/2

Now, again the child's child (Martha) probability for having the disease is = 1/2.

Therefore,

<u>The total probability for Martha's first child to be diagnosed with Galactosemia will be,</u>

$Probability=\frac{2}{3}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{4}\\Probability=\frac{1}{24}$

(Here, we assumed that the child has the disease therefore, the probability was taken to be = 1/4.)

<em><u>Hence, the probability for the first child to have Galactosemia is $\frac{1}{24}$ </u></em>

A cone is formed from a 300-degree sector of a circle of radius 18 by aligning the two straight sides. what is the result when t

vampirchik [111]

The radius of the completed cone is

... 18×(300°/360°) = 15

The height of the completed cone is found from the Pythagorean theorem:

... 15² + h² = 18²

... h = √99 = 3√11

The volume is given by

... V = (1/3)πr²·h = (1/3)π·15²·3√11

Dividing this value by π gives 225√11 cubic units.
