Answer:
the weight of a liquid is 138.37 grams.
Step-by-step explanation:
we are given that the volume of the container=202 ml(milliliter).
also, the density of the liquid is given =0.685 grams over milliliter.
we know that the mass or weight of the liquid is given by:
weight=density×volume .
weight=(0.685×202) grams.
weight=138.37 grams.
hence, the weight of the liquid that exactly fills a 202.0-milliliter container is 138.37 grams.
Answer:
108.505
Step-by-step explanation:
Let's talk money for just a second. Which would you rather have 20 dollars or 20.32 20dollars and 32 cents?
Isn't 20.32 bigger than 20.
You should say yes.
If that is true, then 108.505 should be larger than 108.5 not by much, but still larger.
Answer:
x = $0.85 per pound = 19.85 pounds
y = $2.70 per pound = 1.14 pounds
Step-by-step explanation:
Let
x = $0.85 per pound
y = $2.70 per pound
x + y = 21 (1)
0.85x + 2.70y = 19.95 (2)
From (1)
x = 21 - y
Substitute x = 21 - y into (2)
0.85x + 2.70y = 19.95 (2)
0.85(21 - y) + 2.70y = 19.95
17.85 - 0.85y + 2.70y = 19.95
- 0.85y + 2.70y = 19.95 - 17.85
1.85y = 2.1
y = 2.1 / 1.85
y = 1.14
Substitute y = 1.14 into (2)
0.85x + 2.70y = 19.95
0.85x + 2.70(1.14) = 19.95
0.85x + 3.078 = 19.95
0.85x = 19.95 - 3.078
0.85x = 16.872
x = 16.872 / 0.85
x = 19.85
x = $0.85 per pound = 19.85 pounds
y = $2.70 per pound = 1.14 pounds
A+b=9i-8j+7k+(7i-9k)
=9i-8j+7k+7i-9k
=16i-8j-2k
9a+7b=9(9i-8j+7k)+7(7i-9k)
=81i-72j+63k+49i-63k
=130i-72j
|a|=| 9i-8j+7k |
|a-b|=|9i-8j+7k-(7i-9k)|
=|9i-8j+7k-7i+9k|
=|2i-8j+16k|
i hope this is helping
Answer:
The order of the values from greatest to least are as
Step-by-step explanation:
Negative number goes on decreasing in this way as -1,-2,-3,-4,-5... and so on.
So,-11 > -13 > -21
Here the denominator is same and the numerator is in decreasing order i.e greatest to the least that is 21 > 11 > 3 > -11 > -13 >-21 .Therefore, the order is
