(10 + a / 2, 2 + b / 2) = (8, 1)
10 + a / 2 = 8
10 + a = 16
a = 6
2 + b / 2 = 1
2 + b = 2
b = 0
so V(6, 0)
Answer:
Step-by-step explanation:
<u>Surface area:</u>
- S = 2(lw + lh + wh) + 2πrh
- S = 2(9*4 + 9*5 + 4*5) + 2*3.14*2*3 = 239.7 cm² (rounded)
<u>Volume:</u>
- V = lwh + πr²h
- V = 9*4*5 + 3.14*2²*3 = 217.7 cm³ (rounded)
Answer:
C. 10 times greater
Step-by-step explanation:
every time you move left a number space, the value increases by a multiple of 10x (the opposite is true for moving right)
for example:
1.0
10.0
100.0
<u>1</u><u>0</u><u> </u><u>is </u><u>1</u><u>0</u><u>x</u><u> </u><u>greater </u><u>than </u><u>1</u>
<u>1</u><u>0</u><u>0</u><u> </u><u>is </u><u>1</u><u>0</u><u>x</u><u> </u><u>greater </u><u>than </u><u>1</u><u>0</u><u> </u><u>or </u><u>1</u><u>0</u><u>0</u><u>x</u><u> </u><u>greater </u><u>than </u><u>1</u>
<u>*</u><u>notice </u><u>how </u><u>the </u><u>number </u><u>1</u><u> </u><u>is </u><u>moving </u><u>one </u><u>space </u><u>to </u><u>the </u><u>left</u>
