Answer:
A choice.
Step-by-step explanation:
Irrational number is a number that cannot be written in a fraction form. All square roots are classified as an Irrational number unless can be evaluated to Rational number.
From A choice, you cannot evaluate the square root of 7 into any rational number. Therefore, it is an Irrational number.
B choice, even though there is a square root, but you can still evaluate from square root of 4 to 2.
For C and D, both are integers. Integers are classified to be Rational Number. Therefore, C and D both are rational.
The 7-digit number we are looking for is 8,92a,bcd
"The value of the thousands digit is double that of the ten thousands digit."
The value of the ten thousands digit is 2. Thus the value of the thousands digit is 4.
The 7-digit number we are looking for is 8,924,bcd
"The sum of all its digits is 24."
8+9+2+4+b+c+d = 23 + b+ c+ d
Thus b+c+d = 1
The digits to the tens and hundreds places are the least and same value.
These two digits (b and c) must be 0, because b+c+d = 1
That means that the digit "d" must be equal to 1.
The 7-digit number we are looking for is 8,924,001
This number is the only number that satisfies all the conditions stated in the question.
Answer: 8x
Step-by-step explanation:
Product stands for multiplication, so we need to use (×)
Let x = the number.
----------------------------------------------
The product of 8 and a number
8 × x=8x
Answer:
100g : 60g : 80g
Step-by-step explanation:
5+3+4 =12 total parts
(5/12 of 240)
5/12 x 240 = 100g
3/12 x 240 = 60g
4/12 x 240 = 80g
Check:
100g + 60g + 80g = 240g
Hope this helps!
Answer:
No solutions
Step-by-step explanation:
The graph does not contact the x axis
There are no real answers for this reason.
