Answer:
Legs: [tex]x[/tex]
Hypotenuse: [tex]\sqrt{2}\cdot x[/tex]
Step-by-step explanation:
In this case, a 45-45-90 right triangle is a right triangle whose legs have the same length and hypotenuse is [tex]\sqrt{2}[/tex] times the length of any of the legs. Then, the dimensions of this triangle are, respectively:
Legs: [tex]x[/tex]
Hypotenuse: [tex]\sqrt{2}\cdot x[/tex]
A die has 12 faces numbered 1 through 12. On the die, 5 of the faces show prime numbers, so the theoretical probability of rolling a prime number is 5/12. Which is the most likely prediction for the number of times a prime number will occur when rolling the number cube 300 times?
Answer:
5/12 * 300 = 125 times

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°

Answer:
5
Step-by-step explanation:
5 × 5 × 5= 125 so 5 is the cube root
Answer:
5Step-by-step explanation:
I have this information memorized. The cube root of 125 is simply 5, because 5 x 5 x 5 = 125.
So your answer is 5.

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

(x+5)(x-4)(x+2) is identical to x^3+ax^2
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

4.2x-1.4y= 2.1 what is Y plz i need help and i don't understand
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

. 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?
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

Use substitution to solve the system of equations.how many solutions are there?
1/2x-1/3y=5
X=2/3y+10
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
