Select the procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 6 cm, 8 cm, 9 cm, and 13 cm.
A. Knowing that 6^2 + 8^2 = 10^2, draw the 6 cm side and then the 8 cm side with a right angle between them. The 10 cm side will fit to form a right triangle.
B. Knowing that 6^2 + 8^2 > 9^2, draw the 6 cm side and then the 8 cm side with a right angle between them. The 10 cm side will fit to form a right triangle.
C. Knowing that 8^2 + 9^2 does not equal 10^2, draw the 8 cm side, then the 9 cm side with a right angle between them. The 10 cm side will fit to form a right triangle.
D. Knowing that 6^2 + 8^2 = 10^2, draw any two of the side with a right angle between them. The third side will fit to form a right triangle.

Step-by-step explanation:
y=5
Answer:
m∠C = 32°
m∠D = 82°
m∠DEC = 66°
Step-by-step explanation:
Exterior Angle Theorem says that the degree measure that with an angle forms a straight line (Ex. Angle DEF in the picture) is equal to the sum of the two other angles in the triangle. This means that the measure of angle DEF is equal to the measure of angle DCE plus the measure of angle CDE. This would mean that 9y + 1 + 3y + 5 = 114, meaning that 12y + 6 = 114, which means that 12y = 108, which means that y = 9. If we plug 9 in for all of these values, we get that angle D is 9 * 9 + 1, which is 82 and that angle C is 3 * 9 + 5, which is 32. Next, we know that the sum of angles in a triangle is 180, so we subtract 32 and 82 from 180 to find the measure of angle DEC, and this is 66 degrees.

Rearrange x= 3g + 2 to make g the subject
Answers
3g + 2 = x
3g = x - 2
g = (x - 2)/3
Answer:
g = 1/3 x - 2/3
Step-by-step explanation:
x =3g + 2
Switch sides:
3g + 2 = x
Take away 2 from both sides:
3g = x - 2
Divide both sides by 3:
g = 1/3 x - 2/3

Because of all the variables in the side lengths, we don't have enough information to use side-angle-side similarity.
We do have two angles of one triangle congruent to two corresponding angles of the other triangle, so we can use angle-angle similarity.
Sides AE and AD are corresponding sides. Sides AC and AB are corresponding.

What is the greatest surface area of a rectangular solid that can be built from 16 identical unit cubes?
Answers
Answer and explanation:
The surface area of a solid is the sum of the areas of all faces of the solid. The surface area of a cube is calculated using the formula 6a² since a cube has 6 faces in total likewise a cuboid.
We can say the rectangular solid is a cuboid and to find the surface area of the cuboid we add up the surface area of all 16 cubes
Surface area is therefore 16×6a²

A certain college enrolled 29,000. It was reported 54 percent were female and 46 percent were male. In addition 61 percent were over the age of 25. How many students were in each category if 30 percent of those over the age if 25 were male
Answers
Answer:
Step-by-step explanation:
Total number of students = 29000
Number of female = 54% of 29000
54/100 x 29000 = 15660 students
Number of male = 46% of 2900
46/100 x 29000= 13340 students
61% of 29000 are over 25 years
61% of 29000= 61/100 x 29000
= 17690 students
Of the pupils over the age of 25, 30% are male
30% of 17690 students are male
30/100 x 7690 =5307 students
The number of females over the age of 25 = 17690 -5307
17690 - 5307 = 12383 female students.

What is whole number?The whole numbers are the numbers without fractions and it is a collection of positive integers and zero. It is represented by the symbol “W” and the set of numbers are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,……………}. Zero as a whole represents nothing or a null value.
According to the question
First, we consider that if we add together three equal numbers, the result must be a multiple of three. For example, 7 + 7 + 7 = 21, or 11 + 11 + 11 = 33.
Algebraically, we'd say that n + n + n = 3n.
So this means that if we subtract the first number (the one that's a multiple of 19) from 97, we will have a result that is a multiple of 3.
What could the first number be? 19, 38, 57 or 76 . Any other value is larger than the sum of 7, which is not possible if all the integers are non-negative.
Based on this, we can find all possible sums of the other four numbers, by subtracting each of the numbers above from 96:
96 - 19 = 77
96 - 38 = 58
96 - 57 = 39
96 - 76 = 20
Remember what I said earlier? The other four numbers must add to a multiple of 3. The only one of those sums above that is a multiple of 3 is 39. Therefore, we conclude that the first number is 57, and the other four numbers are each 13 (because 39 / 3 = 13).
Hence, other four number is 13
