Answer:
19/4 or 4.75
Step-by-step explanation:
Week 1: 1 1/8 = 1.125
Week 2: -2 5/8 = -2.625*
Week 3: 1 3/4 = 1.75
Week 4: -1 1/2 = -1.5
Week 5: 2 1/8 = 2.125*
2 1/8 - (-2 5/8) = 2.125 - (-2.625)
19/4 or 4.75
STEP 1:
convert meters to centimeters
100 cm= 1 meter
= 100 cm/m * 2.5 m
= 250 cm
STEP 2:
x= length of first shelf
2x+18= length of second shelf
x-12= length of third shelf
x+4= length of fourth shelf
since the whole board has to be used, add lengths of all shelves and set it equal to the whole length of the board (250 cm).
x + (2x+18) + (x-12) + (x+4)= 250 cm
combine like terms
5x + 10= 250
subtract both sides by 10
5x= 240
divide both sides by 5
x= 48
STEP 3:
find length of second shelf
= 2x + 18
= 2(48) + 18
= 114 cm
CHECK:
x + (2x+18) + (x-12) + (x+4)= 250
48 + (2(48)+18) + (48-12) + (48+4)= 250
48 + (96+18) + 36 + 52= 250
48 + 114 + 36 + 52= 250
250= 250
ANSWER: Shelf two is 114 cm.
Hope this helps! :)
It would be 243 because it saids all-together the number if figurines Mike and Alex. 186+57=243
Answer:
Step-by-step explanation:
The first time the basketball bounces it reaches a height of 
.
The second time the basketball bounces it reaches a height of ![(0.722) (0.722) (6) = [(0.722) ^ 2] (6)](https://tex.z-dn.net/?f=%280.722%29%20%280.722%29%20%286%29%20%3D%20%5B%280.722%29%20%5E%202%5D%20%286%29)
. Therefore, after b rebounds the height that the basketball will reach is given by:
30% , 3/5 , 0.8
Checking:
30%=30%
3/5=60%
0.8=80%
