Answer:
2.34 grams
Step-by-step explanation:
In this problem, we need to find how many grams in 2.34mL. To solve the problem, we must know the relationship between grams and millilitre.
We know that,
1 milliitre = 1 gram
Hence,
2.34 mL = 2.34 grams.
-2 / 1/4
If you are dividing you have to switch 1/4 to 4/1
-2/1 / 4/1
= -8

Answer:
646.04 cm³
Step-by-step explanation:
<u>Cube volume formula:</u>
V=l*w*h
V=8*8*8
V=512
<u>Hemisphere volume formula:</u>
V=(4/3πr³)1/2
V=(4/3π4³)1/2
V=128/3
<u>Add both together</u>
128/3 + 512 ≈ 646.04cm³

Answer:
x = 0
y = 5
z = -5.
Step-by-step explanation:
X-5y-z=-20
-2x-y-6z=25
-x-4y-z=-15
Add equation 1 and 3:
-9y - 2z = -35 .......... A
Multiply the first equation by 2:
2x - 10y - 2z = -40
Now add this to equation 2:
-11y -8z = -15.............B
Now multiply equation A by -4:
36y + 8x = 140.........C
Add equations B and C:
25y = 125
y = 5.
Substitute for y in equation A:
-9*5 - 2z = -35
2z = -45 + 35 = - 10
z = -5.
Now find x by substituting for y and z in the first equation:
x - 5(5) - (-5) = -20
x - 20 = -20
x = 0.
