What is 10 5/16-(5 1/4 +2 9/16)

1 answer:

4 0

$10\frac{5}{16}-(5\frac{1}{4}+2\frac{9}{16})=\ \ \ \ | make\ common\ denominator\\\\
10\frac{5}{16}-(5\frac{4}{16}+2\frac{9}{16})=\ \ \ | omit\ the\ bracket\\\\
10\frac{5}{16}-5\frac{4}{16}+2\frac{9}{16}=7\frac{5-4+9}{16}=7\frac{10}{16}\\\\
Solution\ is\ 7\frac{10}{16}.$

What’s the answer for m

Archy [21]

Answer:

$m\angle D=35.5^o$

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal interior angles

In this problem

Triangle CDE is an isosceles triangle

because

EC ≅ DE

therefore

$m\angle C=m\angle D$ ----> equation A

Remember that

The sum of the interior angles in any triangle must be equal to 180 degrees

$m\angle C+m\angle D+m\angle E=180^o$ ----> equation B

$m\angle E=109^o$ ---> equation C

substitute equation A and equation C in equation B

$m\angle D+m\angle D+109^o=180^o\\$

$2m\angle D=180^o-109^o$

$m\angle D=35.5^o$

A psychology class consists of 14 males and 36 females. if the professor selects names from the class list using random sampling

Sonbull [250]

The probability of selecting a female student for the first picking is $\frac{36}{50} = \frac{18}{25}$
The number of students left to select from after the first two students selected is 50 - 2 = 48 students, which consist of 34 females (two have been selected) and 14 males (none has been selected so far)
The probability that the third pick is a male is $\frac{14}{48}= \frac{7}{24}$
