Step-by-step explanation:
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.
Answer:
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.

Hey there!
Your answer is c)
Answer:
2√5
Step-by-step explanation:
The triangle that's shown on the page is a special isosceles right triangle with angle measures of 45° - 45° - 90°
Since one of the side length that sees 45° angle measure is 2√5 the other also has to be equal to this value so the answer is 2√5

A cube has a surface area of 150
cm squared. Find the side length of the cube in cm.
Answer:
Step-by-step explanation:
6 faces have an area of 150 cm^2
1 face has an area of 150/6 = 25 cm^2
The formula for the area of one face of a cube = s^2 which is the length of a side squared.
s^2 = 25
sqrt(s^2) = sqrt(25)
s = 5

At the school election there were three candidates. Isabella got 40 votes, Amelia got 60 votes and Mason got ⅓ of the votes. How many people voted in the election?
Answer: 150 people voted in the election.
Step-by-step explanation:
Let x = Total number of votes.
Mason got [tex]\dfrac{x}{3}[/tex] votes.
Isabella got 40 votes, Amelia got 60 votes.
Then,
Combined votes = [tex]40+60+\dfrac{x}{3}=x[/tex]
[tex]100=x-\dfrac{x}{3}\\\\100=\dfrac23x\\\\ x=100\times\dfrac32\\\\ x=50\times3\\\\ x=150[/tex]
Hence, 150 people voted in the election.

Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the temperature in Hawaii on Thursday was 85°F while thee temperature in Colorado on Thursday was 5°F.
The expression(s) that represent this situation using the absolute value of the difference will be:
= 85°F - 5°F
= 80°F

y = 5x − 7 −3x − 2y = −12 solved by substitution please show the work too so i can understand
Answer:
y=3, x=2
Step-by-step explanation:
-3x-2(5x-7)=-12 (substitute y=5x-7)
simplify
{-13x+14=-12\}
isolate x for -13x +14=-12: x=2
for y=5x-7 substitute x=2
simplify y=3

A shop sells packs of black pens, packs of red pens and packs of green pens.
There are
2 pens in each pack of black pens
5 pens in each pack of red pens
6 pens in each pack of green pens
On Monday, the ratio of number of packs of pens sold was Black : Red : Green = 7 : 3 : 4
A total of 212 pens were sold.
Work out the number of green pens sold.
Answer:
The number of green pens sold are 96 green pens
Step-by-step explanation:
The given parameters for the packs of pens sold by the shop are;
The number of pens in each pack of black pens = 2 pens
The number of pens in each pack of red pens = 5 pens
The number of pens in each pack of green pens = 6 pens
The ratio of number of packs of pens sold Black : Red : Green = 7 : 3 : 4
The total number of pens sold = 212
Let 'x' represent the number of packs of pens sold
Therefore, the fraction of the packs the pens sold that are black pens = 7/(7 + 3 + 4) = 7/14 = 1/2
∴ 1/2 of the number of packs of pen sold = packs black pens = x/2
The fraction of the packs the pens sold that are red pens = 3/14
∴ 3/14 of the number of packs of pen sold = packs of red pens = 3·x/14
Similarly, we have;
The fraction of the packs the pens sold that are green pens = 4/14 = 2/7
∴ 2/7 of the number of packs of pen sold = packs of green pens = 2·x/7
Therefore, we have;
x/2 × 2 + 3·x/14 × 5 + 2·x/7 × 6 = 212
Where;
x/2 × 2 = The number of black pens sold
3·x/14 × 5 = The number of red pens sold
2·x/7 × 6 = The number of green pens sold
∴ 53·x/14 = 212
x = 212 × 14/53 = 56
∴ The number of packs of pens sold = x = 56 packs
The number of green pens sold = 2·x/7 × 6 = 2 × 56/7 × 6 = 96
The number of green pens sold = 96 pens.
