Answer:
Step-by-step explanation:
Each atom of the gas weighs 1.67 ⋅ 10−24 grams. 6.71 grams, because (5.04 + 1.67) ⋅ (1023⋅ 10−24 ) = 6.71. ... 0.67 grams, because (5.04 + 1.67) ⋅ (1023⋅ 10−24 ) = 6.71 ⋅ 10−1.
Answer:
480
Step-by-step explanation:
The simplest form of a^2-ab is given by 3x^3 + x^2 + 6x - 9.
We have given that,
a = x^2,
b = 3x + 2,
c = x – 3
We have to determine ab- c^2.
<h3>
What is the meaning of the simplest form?</h3>
A fraction is in its simplest form when the numerator and the denominator have no common factors besides one.
ab- c^2

Perpendicular lines will have negative reciprocal slopes. Example : if u r given a slope of 1/3, to find the negative reciprocal, flip the slope and change the sign. So the negative reciprocal of 1/3 is -3/1 or just -3. So slope 1/3 and slope -3 are perpendicular.
==================
equation 2 :
4x + 2y = 6
2y = -4x + 6
y = -2x + 3...the slope here is -2....a perpendicular line will have a slope of 1/2.
y = (a/3)x - 6......so we have to make a/3 = 1/2......1.5/3 = 1/2
so a = 1.5
===================
eq. 2 : 3/4x + 2
not sure what the entire equation is.....but it looks to have a slope of 3/4. That means a perpendicular line will have a slope of -4/3.
3y + ax = 9
3y = -ax + 9
y = (-a/3)x + 3.....therefore, a has to be 4
Breads/cereals;
11 * 140 = 1540 calories
Fruits/vegetables;
9 * 60 = 540 calories
Meat/milk;
x * 180 = 2800 - (1540 + 540)
180x = 2800 - 2080
180x = 720
x = 4 servings
