Answer
Mandisa uses more balloon per animal.
Amira and Mandisa made the same amount of balloon animals.
Explanation
Mandisa uses 5 balloons per animal.
You can find this out by putting the difference between two of the y values (output, dependent variable, in this case balloons) over the difference between two of the x values (input, independent variable, in this case animals). Let's take 225 and 125 from the y value and 20 and 40 from the x value. Mandisa uses 225-125=100 balloons per 40-20=20 animals. Mandisa uses 5 balloons per animal. 5 is more than 4 (how many balloons Amira uses for each animal), so Mandisa uses more balloons per animal.
Amira and Mandisa made the same amount of balloon animals.
Now you can divide the number of balloons they had at the beginning by the number of balloons per animal to find out how many animals each person made. Amira started with 260 balloons and used 4 balloons for each animal. Amira made 260/4=65 animals.
If Mandisa used 100 balloons to make 20 animals, she would have had 225+100=325 balloons at the beginning. Mandisa made 325/5=65 animals.
Answer:
j=1.571
Step-by-step explanation:
to get j by itself you have to divide 7 by 11
so,
11/7=j
j=1.571
Answer:
282/17
Step-by-step explanation:
6+3/34 =207/34
and 207/34+21/2=282/17
Answer:
For a triangle with <em>a</em> = 33, <em>c</em> = 48 and the angle , the missing side is <em>b = </em>60.4, and the missing angles are and .
Step-by-step explanation:
The Law of Sines says that in any given triangle, the ratio of any side length to the sine of its opposite angle is the same for all three sides of the triangle. This is true for any triangle, not just right triangles.
We know two sides <em>a</em> = 33, <em>c</em> = 48 and the angle , so we use the law of sines to find the angle as follows:
One of the basic properties of triangles is that the sum of the measure of angles, in every triangle, is 180°.
So,
To find the side <em>b</em> we use the law of sines:
$37,000 - $27,000 = $10,000 over 5 years
It depreciates $2000 a year
2007= $27,000 - $2000
2007 = $25,000
2008=$25,000 - $2000
2008= $23,000
2009= $23,000 - $2,000
2009= $21,000
The boat will be worth $21,000 in 2009
