Answer:
he counted from 32 to 40 , and not to -40
Step-by-step explanation:
the difference is 72 degrees
Complete question
To find
, Beau found
and
. He said that since 5 is between 4 and 9,
, is between 2 and 3. Beau thinks a good estimate for
, is
Is his estimate high or low? How do you know?
Answer:
The estimation is high because 5 is very close to 4 so
will also be very close to
which is lower than the estimate
In order to get a good estimate
The first step is to choose a number between 2 and 3 let say 2.8 , 2,85 , 2.9 and the square them
i.e



From here we can see that
lies between 2.2 and 2.3 but is closer to 2.2
So a good estimate for
is 2.2
Step-by-step explanation:
Answer:
B. X squared is -3 times -3, which is equal to 9.
Step-by-step explanation:
Answer:
1. -60
2. 32
Step-by-step explanation:
The property of each given rational number operation are respectively; Commutative Property; Closure Property; Associative Property; Closure Property; Distributive Property
<h3>What is the property of the rational number?</h3>
The main properties of rational numbers are:
a) The property used here is commutative property which says that;
a + b = b + a.
This tallies with the operation used on the rational numbers.
b) The property used here is called Closure Property. This is because for two rational numbers say a and b, the results of addition, subtraction and multiplication operations gives a rational number.
c) The property used here is called associative property because it states that; a * (b * c) = (a * b) * c.
d) The property used here is called Closure Property. This is because for two rational numbers say a and b, the results of addition, subtraction and multiplication operations gives a rational number.
e) The property used here is called distributive property because it states that; a * (b * c) = (ab * ac)
