They are asking what direction is it from point A to point B. hope that helps
So the first one is 1 square meter of ceiling, and it says 1 square meter of cieling is 10.75. <em>So the first one is just that, 10.75</em>
The second one says 10 square meters, so just multiply 10.75, by 10.
In which case you get <em>107.5.</em> So that's the answer.
Third one, it gives you how many ceiling tiles you have. So you divide the 100 tiles by 10.75, which gives you 9.30232558, which becomes <em>9.3</em>
I'm sure you can figure out the last one.
Answer:
Explanation:
<u />
<u>1. First find the density of your chain</u>
- Volume = displaced water volume
= Volume of Final level of water - initial level of water
= 20 ml - 15 ml = 5 ml
- Density = 66.7g / 5 ml = 13.34 g/ml
<u />
<u>2. Second, write the denisty of the chain as the weighted average of the densities of the other metals:</u>
Mass of gold × density of gold + mass of other metals × density of other metals, all divided by the mass of the chain.
Calling x the amount of gold, then the amount of other metals is 66.7 - x:
Then, there are 26.47 grams of gold in 66.7 grams of chain, which yields a percentage of:
- (26.47 / 66.7) × 100 = 39.7%
Answer:
-36
Step-by-step explanation:
le x be 2 then
f(x) = -2-2 =-4
g(x)= 2square +1-2 =3
to find:(f×g)(3)
(-4×3)(3)
=-36
1.5/3=1.66667
2.6/3=2
3.2/9=2/9 (can not be simplified)
4.18/1=18
5.9/27=2/9
6.9/12=3/4
7.28/7=4
8.13/10=13/10(can not be simplified)
9.16/27=16/27(can not be simplified)
10.3/18=1/6
11.4/32=18
