The measure of the side length (that is hypotenuse) of the right-angle triangle will be √202 units.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Let the missing side of this right triangle be х.
Then the measure of the side length (that is hypotenuse) of the right-angle triangle will be
x² = 9² + 11²
x² = 81 + 121
x² = 202
x = √202

1/2x-1/3y=5
X=2/3y+10
Answers
Answer:
one solution
x = 0
y = -15
Step-by-step explanation:
1/2x-1/3y = 5
x = 2/3y+10
substitute x
1/2(2/3y+10)-1/3y = 5
1/3y+5-1/3y = 5
5 = 5
x = 0
-1/3y = 5
-1/3y/-1/3 = 5/-1/3
y = -15

When using the given diagram to determine the area of the pentagon by decomposition, which statements are correct?:
Answer choices:
(A) Area of ∆ABC = 84 in²
(B) Area of ∆ABC = 42 in²
(C) Area of trapezoid = 1/2(14 ÷ 10)8
(D) The area of the pentagon is 180 in²
(E) The area of the pentagon is 138 in²
APPLY TO ALL THAT IS TRUE
Answers
Answer:
Options (B) and (E)
Step-by-step explanation:
Area of ΔABC = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(14)(6)[/tex]
= 42 in²
Area of trapezoid ADEC = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
[Here, [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides and 'h' is the height of the isosceles trapezoid given]
= [tex]\frac{1}{2}(10+14)(8)[/tex]
= 96 in²
Area of the pentagon = Area of triangle ABC + Area of trapezoid ADEC
= 42 + 96
= 138 in²
Therefore, Options (B) and (E) are the correct options.

What translation was used?
Answers
Answer:
up 2, right 3
Step-by-step explanation:
up 2, to the right 3.
The translation was 2 units right and 3 units up.
As per the given data:
We are given AB with the coordinates as, A(-3, -1) and B(2, 1).
After translation, AB becomes A'B' with A'(-1, 2) and B'(4, 4).
We can find out the translation by finding out the change in the corresponding coordinates.
For A to A':
Change in x coordinate = -1 - (-3) = -1 + 3 = 2
Change in y coordinate = 2 - (-1) = 2 + 1 = 3
Increase in x coordinate of 2 units = 2 units right.
Increase in y coordinate of 3 units = 3 units up
Hence, the translation was 2 units right and 3 units up.

Answer:
x = 20
y = 10
m∡8 = 110°
Step-by-step explanation:
m∡1 + m∡2 = 180
5x + y + 3x + y = 180
8x + 2y = 180
m∡1 = m∡8 (they are alternate-exterior angles and are congruent)
5x + y = 3x + 5y
2x = 4y
x = 2y
Substitute '2y' for 'x' in 8x + 2y = 180
8(2y) + 2y = 180
18y = 180
y = 10
x = 2(10)
x = 20
m∡8 = 3(20) + 5(10) = 110°

(x+5)(x-4)(x+2) is identical to x^3+ax^2
Answers
Answer:
a = 3
Step-by-step explanation:
Factorize (x+5)(x-4)(x+2)
(x+5)(x-4)(x+2)
= (x²-4x+5x-20)(x+2)
= (x²+x-20)(x+2)
= (x³+2x²+x²+2x-20x-40)
= x³+3x²-18x -40
Compare with x^3+ax^2
3x² = ax²
3 = a
Rearrange
a = 3
Hence the value of a that makes the expressions identical is 3
. Liliana is renting a beach house for a family vacation. The house charges a $75 cleaning fee plus $95 per night. If Liliana wants to spend a maximum of $645 on the rental, which inequality represents “n”, the number of nights can she afford to rent the beach house?
Answers
Answer:
6 nights
Step-by-step explanation:
Set up your equation:
645=95n+75
then subtract the cleaning fee from the total to remove it from both sides
570=95n
then divid the remaining budget by the $95 per night charge
570/95= n =6
Meaning that she can afford 6 nights in the beach house at that price

4.2x-1.4y= 2.1 what is Y plz i need help and i don't understand
Answers
Answer:
y = -1.5 + 3x
Step-by-step explanation
I'm sorry but I have no time, can someone comment me and explain? Thank you :)
Answer: y = -1.4(2.1 - 4.2x)
Step-by-step explanation:
4.2x - 1.4y = 2.1
Firstly you should move 4.2x over (by subtraction) so the new equation is:
-1.4y = 2.1 - 4.2x
Then you want to multiply everything by -1.4 to take it away from the y side. This will bring you to:
y = -1.4(2.1 - 4.2x)
This can be simplified down to
y = -2.94 + 5.88x
or
5.88x -2.94 = y
