Answer: 2.48
Step-by-step explanation: The 2 isn't big enough to make the 8 round up to a 9.
Look at the picture.

We have:
and Quadrant II (x < 0, y > 0)
Therefore x=-3 and y = 2. Calculate r:
Substitute to the formula of cosine:
Answer: a.
Answer:
x = 5 when y = 12
Step-by-step explanation:
If y is inversely proportional to x, we can say that x1 : x2 = y2 : y1
The order of y2 and y1 respectively are interchanged as y is inversely proportional to x
Now let us simply substitute our known values, and solve for x2;
x1 : x2 = y2 : y1
20 : x2 = 12 : 3
20/x2 = 12/3
12(x2) = 3(20)
12(x2) = 60
x2 = 60/12 = 5
Answer:
1352 pounds
Step-by-step explanation:
128+128=256
256+254=510
510+128=638
2000-638=1352
Answer:
If the number your dividing has a decimal, move the decimal point all the way to the right, counting how many spaces you have moved it. Then, move the decimal point in the number you're dividing the same number of places to the right.
