Answer:
1.- If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.
2.- The square root of a number is that number which when multiplied by itself two times gives us that number.
Example:
Let us use the square root of 64.
√64 = x , so that (x)(x) = 64
We know that, (8)(8) = 64
∴ √64 = 8
The cube root of a number is that number which when multiplied by itself three times gives us that number.
Example:
Let us use the square root of 64
∛64 = x , so that (x)(x)(x) = 64 ,
We know that, 4 x 4 x 4 = 64
∴ ∛64 = 4
Can you tell me a specific name and what grade this is, Cause I have multiple ways of doing this
Answer:
9*11
Step-by-step explanation:
Product means multiplication so to find what Vanessas age is, do 99/9 which gives you 11 and then check it by multiplying 11 and 9 which will get you 99
Answer:
L=22feet
w=19feet
Step-by-step explanation:
Perimeter(p)=82
Length=(L)
Width=(w)
P=2L+2w
2L+2w=82 .......(1)
L-w=3........(11)
From (11) L=3+w
Substitute L=3+w in (1)
2(3+w)+2w=82
Clearing brackets
6+2w+2w=82
6+4w=82
Collect like terms
4w=82-6
4w=76
w=76/4
w=19
Substitute w=19 in (11)
L-19=3
Collect like terms
L=3+19
L=22
The equivalent expression for the given expression (w+9)+3 using associative property is w + 12
<u>Solution:</u>
Given that, expression is ( w + 9 ) + 3
We have to find how do we can use the associative property to write an expression equivalent to ( w + 9 ) + 3
The associative property states that you can add or multiply regardless of how the numbers are grouped
By above definition, we get
(a + b) + c = a + (b + c)
So, now let us apply the above property to the given expression,
Then, ( w + 9 ) + 3 = w + ( 9 + 3 ) = w + 12
Hence, the equivalent expression for the given expression is w + 12
