Answer:
3/5
Step-by-step explanation:
The length 4.8 is given for QX. To find the length of RX add 4.8+3.2. The length of RX is 8.
Substitute 4.8 for QX and 8 for RX.
4.8/ 8
Then, simplify
4.8 and 8 can both be divided by 1.6. This makes the final ratio 3/5.
The length 9 is given for XY. To find the length of XZ add 9+6. The length of XZ is 15.
Substitute 9 for XY and 15 for XZ.
9/15
Then, simplify
Divide 9 and 15 by 3 to simplify. This makes the final ratio 3/5.
The length of YQ is 7.5, and the length of ZR is 12.5.
Substitute 7.5 for YQ, and 12.5 for ZR.
7.5/ 12.5
Then, simplify
Divide 7.5 and 12.5 by 2.5 to simplify. This makes the final ratio 3/5
5+3d-1.5=0.5
3d+3.5=0.5
3d=-3
d=-1
Answer:
The following would be best modeled by an exponential decay function
A.) An island is being eroded away and loses 10% of its beachfront every year.
D.) A machine depreciates (loses value) by $1000 in its first year, by $2000 in its second, $3000 in its third, etc.

Answer:
Step-by-step explanation:
The volume of the metal cuboid = length x width x height = 16 x 8 x 3 = 16 x 24 = 384 cm^3
If this same cuboid is going to be reshaped, then
The volume of the cuboid = The volume of the cube
Therefore,
l^3 = 384
l =
l = 7.268..
l = 7.27cm ( 2dp)
Hope this helps.
