Answer:
C. 7500
Step-by-step explanation:
We must simply find out what 25% of 30,000 is.
Multiply .25 by 30,000 which equals 7,500
In the question, they GIVE you the equation for the line:
y = 1.1 x + 1.37 .
When you look at the graph, you notice that the numbers
are actually thousands, so the equation is really
y = (1.1 thousand) x + (1.37 thousand)
or
y = 1,100 x + 1,370 .
The slope of the line is 1,100 .
Choice 'C' says that, because
the slope of any graph = (change in 'y') / (change in 'x') .
Answer: 2000
Step-by-step explanation:
Set up equation
The total signatures she needs is 4 times as many as she has. From this we can create the equation (4n = total signatures)
We know that the total number of signatures is 8000, so plug this into the equation to get 4n = 8000
Solve for n
Now that we have an equation, we can solve for n by dividing both sides by 4
4n = 8000
n = 8000 / 4 = 2000
Final Answer
Fiona has collected 2000 signatures so far
<span>We have 46°+x°+y°=180°
or </span>x°+y°= 180°-46°
and we have x°+y°= 134°
This is the first two-order equation so there are many solutions of the form (x°;y°)
with y°=134-x°. For example (1°;133°) or (90°; 44°)...

Answer:
Fifth Day (1024 pounds)
Step-by-step explanation:
For every subsequent day, he collected 4 times the previous day.
This increase is a ratio/product, therefore the sequence is a geometric sequence.
The nth term of a geometric sequence,
Where:
a=first term
r=common ratio
n=number of terms
Corey collected 4 pounds of newspaper on day 1., a=4
After day one he collected 4 times the amount and for every subsequent day, he collected 4 times the previous day. r=4
We want to determine on which day he will first collect over a 1000 pounds of new paper.
In order to apply law of indices, we look for the next term greater than 250 which is an index of 4.
Therefore on the fifth day, he will collect an amount over 1000 pounds, precisely 1024 pounds.
