Answer:
C
Step-by-step explanation:
Since the triangle is right with hypotenuse QR
Use Pythagoras' identity to solve for QR
The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
QR² = 8² + (8
)²
= 64 + 192
= 256 ( take the square root of both sides )
QR =
= 16
X^2-14x+49=0
Factor
(x-7)(x-7)
Check
-7-7=-14
-7*-7=49
Use ZPP
x-7=0
x=7
Final answer: x=7
Answer:
30 is the cost of clothes Kyle bought.
Step-by-step explanation:
Given: Kyle spend 1/5 of his money on clothing.
Remaining money is 120.
Lets assume the total money Kyle had be "x".
∴ Money spent on clothes = 
Now, putting up value in the equation to find the total amount of money.
We know, money remaining is 120

Taking LCD subtract the fraction.
⇒ 
⇒ 
⇒
Multiplying 5 both side
⇒
dividing 4 on both side.
∴
∴ x= 150
Kyle has total 150 money to spend.
Kyle spent
of his total money on clothing.
⇒ cost of clothes kyle bought= 
Hence, Kyle spent 30, which was the cost of clothes kyle bought.
Well if you get 60 dollars every day we can represent that as 60d
We can set that equal to 289999 to solve for days, d.
289999 = 60d
289999/60 = d
4,833.3166667 = d
So 4,834 total days
