Answer:
comparing both equation we get,
2X+1=X+9
or, X=8
Y=X+9
or, Y=17
therefore the required solution is (8,17)
Answer:
Step-by-step explanation:
volume = area of base * height = area of base * 9 = 72
-> area of base = 72/9 = 8
let a,b,c be the length of sides of isosceles right triangle base
we have a = b and a*b/2 = 8 ft2
-> a*a/2 = 8ft2
-> a*a = 16
-> a=4ft=b
have c^2 = a^2 + b^2 = 16 +16 = 32
-> c =
= 5.656 ft
Since i dont know that is DF, i calculate both a,b and c

Answer:
A) Silvie is incorrect; the sum of a rational number and an irrational number is always irrational
Step-by-step explanation:
The concept of adding rational and irrational numbers states that the result will always be irrational.
Take for instance the addition of 4.5 and 3.142857
4.5 is a rational number because it can easily be expressed in fractions while 3.142857 is irrational because it can't be expressed as a simple fraction.
The addition of these two numbers gives 7.642857
7.642857 is an irrational number.
Similarly, any sum of two numbers (rational and irrational) will always result in irrational number.
Hence, Silvie is incorrect.
Answer:
500 mL
Step-by-step explanation:
1 L = 1,000 mL
-> We use the formula of L * 1,000 = mL
1,000 mL / 2 = 500 mL
-> We only have half of the L, so we can divide it by 2 to get the correct number of mL
