Answer:
a real number such as π or an integer such as 42. The value of a variable or a constant is any number or other mathematical object assigned to it.
Answer:
A 70
Step-by-step explanation:
We know that angle B and angle C are equal because this is an isosceles triangle and the angles at the base of the equal sides are equal.
The three angles of a triangle add to 180 degrees
A + B+ C = 180
40 + C + C = 180 since B = C
Combine like terms
40 + 2C = 180
Subtract 40 from each side
40-40 + 2C = 180-40
2C = 140
Divide by 2
2C /2 =140/2
C = 70
Answer:
The first one is by using your mind. If you know that factorial of any non negative integer denoted by n!
defined as
n!=n(n−1)(n−2)⋯3⋅2⋅1
then 5!=5∗4∗3∗2∗1. You can calculate it in your mind which will give you 5!=120.
That's it.
The next method is using your calculator. In my calculator Casio fx-991es, I pressed 5 and then shift+x−1
button and I got 120. Similarly, you can use Google to calculate it like I did and got this.

Find 5 days :
----------------------------------
1 day = 1.5km
5 days = 1.5 x 5 = 7.5 km
----------------------------------
Convert km to m
----------------------------------
1 km = 1000 m
7.5km = 7.5 x 1000
7.5 km = 7500 m
--------------------------------------------------------------------
Answer: She walked 7500 m
