The answer is (1,-2). Here’s the work
If we take 6/15 and want to make 2/a equivalent to it, we first find out what was done to 6 (the numerator) to make it a 2. The 6 was divided by 3. So we do the same for 15.
15/3=5
The 3rd fraction is 2/5.
You use a similar method for the 4th fraction, b/120.
Now, we find out what was done to 15 (the denominator) to make it a 120.
The 15 was multiplied by 8. So we do the same for 6.
6*8=48
The 4th fraction is 48/120.
For the last fraction 16/c, we use 2/5 as one numerator (16) is a multiple of the other (2).
2 was multiplied by 8 to get to 16, so we do the same for 5.
5*8=40
The last fraction is 16/40.
The answer would be B) AD=DC, the reason why is because line AD is a reflection of line DC
Answer:
1766 using 3.14 for pi
1767 using the pi button
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
we need to know the radius
r =d/2 = 15/2 = 7.5
V = 4/3 (pi)( 7.5)^3
V =562.5 pi
Approximating pi by 3.14
V = 562.5 (3.14)
V =1766.25
To the nearest whole number
V = 1766
If you use the pi button
1767.14586
To the nearest whole number
1767
To determine this in a very fast and efficient way, divide the numerator by the denominator.
904 / 100 = 9.04
Now since we have our hundredths place as 4, divide 100 by 4 to find the fraction (0.04 is the rate).
100 / 4 = 25.
For every 0.04 we gain, we gain 1/25.
D.) 9 1/25 is your answer.
I hope this helps!
