Three pieces of wood measure 20 cm, 41 cm, 44 cm. If the same amount is cut off each piece, the remaining length can be formed into a right triangle. What is the length that is cut off?
Answers
The length that can be cut off from the three given pieces of wood equally to form a right triangle is 5 cm
Given parameters:
dimension of the three pieces of wood = 20 cm, 41 cm and 44 cm
To find:
the length that is cut off to form a right trianglelet the length that is cut off from each of the wood = y
From Pythagoras theorem, we will have the following equation.
[tex](44-y)^2 = (20-y)^2 + (41-y)^2\\\\expand \ the \ equation \ as \ follows;\\\\1936 - 88y + y^2 = 400 - 40y + y^2 + 1681 - 82y + y^2\\\\simplify \ by \ collecting \ similar \ terms \ together\\\\(1936 - 400- 1681) + (-88y + 40y+ 82y) + (y^2 - 2y^2) = 0\\\\-145 +34y - y^2 = 0\\\\multiply \ through \ by \ (-1)\\\\y^2-34y + 145 = 0\\\\factorize \ the \ above \ quadratic\ equation\\\\y^2 -5y - 29y + 145 = 0\\\\y(y - 5) -29(y - 5)=0 \\\\(y -5)(y-29) = 0\\\\y = 5 \ \ \ or \ \ \ \ y = 29[/tex]
Since the least measurement of one of the pieces of the wood is 20 cm, we cannot cut off 29 cm.
Thus, the highest amount we can cut off equally is 5 cm

Determine the measure of x in the figure below.
show how you go the answer so I can see if it makes sense!!!
Answers
Answer:
138
Step-by-step explanation:
x is an exterior angle of a triangle.
If you didn't know, an exterior angle of a triangle is equal to the sum of its opposite interior angles.
The opposite interior angles of x have measures of 80 degrees and 58 degrees.
Hence, x = 80 + 58 = 138
Answer:
138
80+58 = 138
180 - 138 = 42
42+x = 180
x = 180-42 = 138

The coldest place is in Utah is Middlesink,near Logan.One day the temperature there was -17 degrees.You drive from Middlesink to salt lake where the temperature is 30 degrees.What is the change in temperature?
Explain.
Answers
Answer:
47 degrees
Step-by-step explanation:
The number system goes from negative numbers, to zero, to positive numbers. To get to zero from a negative number, you add the positive version of your number to get to zero. In this case we have to add 17 to get to zero. So our answer is 30+17. Because once we get to zero, we know there is 30 degress to get to the temp in Middlesink. So it is a 47 degree change.
Step-by-step explanation: The difference between the two is 47 degrees. The equation is 30-(-17).When you subtract a negative it's really the same as adding.

In March she sent 752 texts
In April she sent 617
Step-by-step explanation:
The phone bill is 35 + additional texts, so in both bills the value relative to the texts are:
72.6 - 35 = 37.6 for March
65.85 - 35 = 30.85 for April
Each texts costs 0.05, so if we divide the value relative to the texts by 0.05 we will have the number of texts she sent:
37.6/0.05 = 752 texts
30.85/0.05 = 617 texts

Apples are cut into 8 pieces to be shared among some children. Twenty-two bags of seven apples are used. How many pieces of apple are cut?
Answers
Answer: 1232 pieces
Work Shown:
1 bag = 7 apples
22 bags = 22*7 = 154 apples
So we have 154 apples to work with in total.
Each of those apples is cut into 8 pieces, giving us 8*154 = 1232 pieces
We can write it as one single calculation to say 22*7*8 = 1232
the sum of two numbers is 63. one ninth of the first number plus one sixth of the second number is 21. find the numbers
Answers
Answer: x= -189, y =252
Step-by-step explanation:
Let the first number be x and second number be y
so
x + y = 63
x = 63-y
now
1/9 of x + 1/6 of y = 21
x/9 + y/6 = 21
substituting x's value from equation i
(63-y)/9 + y/6 = 21
(378-6y+9y)/54 = 21
378+3y = 1134
3y = 1134-378
so, 3y = 756
so, y = 756/3
so, y = 252
now
x = 63-252
so, x = -189
