Answer:
216 milliliters of compound A are needed.
Step-by-step explanation:
There are two unknowns for the constituents of the final 576 milliliters of the drug:
amount of compound A (which we name A), and
amount of compound B (which we name B)
So we know two things that can be written in equation form;
1) there are 3 milliliters of A every 5 milliliters of B:
2) the chemist mixes 576 milliliters of the drug:
So we now replace B with its expression in terms of A (from our first equation) in the second equation, and solve for A:
So 216 milliliters of compound A are needed.
The "gradient of F" here is the following sum:
(partial of F with respect to x)i + (partial of F with respect to y)j + (partial of F with respect to z)k.
Please, use "^" to denote exponentiation: F(x, y, z) = x2yz − xyz3 should be presented as <span>F(x, y, z) = x^2yz − xyz^3.
</span>The partial of F with respect to x is 2xyz. That with respect to y is
x^2z. That with respect to z is -3xyz^2.
Thus, your gradient is
G(x,y,z) = 2xyz i + x^2z j + -3xyz^2 k.
Answer:
9
Step-by-step explanation:
2 ( ) = 18
Remember that bracket sign means multiplication. So, if we divide both sides by 2, we have
( ) = 18/2
( ) = 9
The missing integer is 9
Answer:
30% or 0.3
Step-by-step explanation:
Divide 12 by 40
Convert to percentage by multiplying by 100
0.3*100 = 30
→ 30%
