The most common base used today is the decimal system which means 1 to 9.
The binary system is base two and it only uses the numbers 1 and 0. It does not go over 1. So base 5 is a number system that doesn’t go over four. It’s a little hard to understand until you do some questions relating to it.
1)
= 24z^7
answer
A. 24z^7
2)
= 24 x^2y^9
answer
D. 24 x^2y^9
3)
=w^12z^18
answer
C. w^12z^18
4)
= 4x^6
answer
B. 4x^6
29.) This is simply interpreting the linear function.
The function:
96+2.1x
a.) The 96 is what you start with from the beginning. So, we know Rachel weighed 96 ounces when she was born.
b.) Again, interpretation. The 2.1 is the slope, or the change in the line. So we know that Rachel gains 2.1 ounces each day.
30.) For this one, you just have to plug 9 into the equation for x.
3 1/8 is the answer because 5x5=25 divided by 3 and you get roughly 24 with one left over so you put the one left over in a fraction hence 1/8.
have a nice day!
When it is 3:00 the minute hand and the hour hand would form a 90 degree angle making a right triangle. If you use the Pythagorean theorem you can find the distance between the tips of the hands.
14^2+9^2=x^2
196+81=x^2
277=x^2
X=16.64ft when rounded
