Using Pythagoras Theorem,
(b is the length of the ladder from the ground)
11x11=6x6+(b^2)
121-36=(b^2)
85=(b^2)
b= 9.219544457292887
b is approximately 9.2
1. D - Since it's random, everyone has an equal chance of being picked
2. B - Since the people are already registered voters it would be easier to get a response from them. Plus, picking ever 10th person makes it random.
3. false - a fair question wouldn't make assumptions about the population
4. B - "Don't you think" causes the answerer to be pushed towards saying yes
hope this helps :)
If the 2 given points are endpoints, then we're in business. The formula for the midpoint is
. If the endpoints of our segment are the coordinates (1,2) and (12,14), our formula would be filled in as follows:
which simplifies to (13/2, 8). See? It's pretty simple once you know how to do it.
Answer:
Adult= $24
child= $21
Step-by-step explanation:
first let's create an equation for each one.
Day 1: 7x+8y=168
day 2: 14x+13y=294
By doing so we can either graph and get the points for x,y or we can substitute each (x=0) (y=0) and solve manually.
x-int.= (24,0)
y-int.=(0,21)
Answer:
C. 148
Step-by-step explanation:
Equation: (12,000-8,448)÷24=x
12,000-8448=3552
3552÷24=148
x=148
