A mixture contains 3.7 × 10–6 grams of carbon powder and 0.000092 grams of ammonium carbonate.
What is the difference in the amounts of carbon powder and ammonium carbonate?
Answer:
The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.
Step-by-step explanation:
According to this statement, we have a mixture with [tex]3.7\times 10^{-6}[/tex] grams of carbon powder and [tex]92\times 10^{-6}[/tex] grams of ammonium carbonate. The difference between those amounts consist in subtracting the latter quantity for the former one. That is:
[tex]\Delta m = 92\times 10^{-6}\,g \,-\,3.7\times 10^{-6}\,g[/tex]
[tex]\Delta m = 88.3\times 10^{-6}\,g[/tex]
The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.

You want to wrap a gift shaped like the regular triangular prism shown. How many square inches of wrapping paper do you need to completely cover the prism?
length 11 in
height 8.7 in
width 10 in
7.
The width of a rectangle is 33 centimeters. The perimeter is at least 776 centimeters.
a. Write and solve an inequality to find the length of the rectangle.
b. Write an inequality to find the area of the rectangle in square centimeters.
A. 2(33) + 2ℓ ≤ 776; ℓ ≤ 355; A ≤ 33(355)
B. 2(33) + 2ℓ ≥ 776; ℓ ≥ 335; A ≥ 33 + 335
C. 33 + ℓ ≥ 776; ℓ ≥ 743; A ≥ 33(743)
D. 2(33) + 2ℓ ≥ 776; ℓ ≥ 355; A ≥ 33(355)
Answer:
D. 2(33) + 2ℓ ≥ 776; ℓ ≥ 355; A ≥ 33(355)
Step-by-step explanation:
Answer:
Width of the rectangle is given to be 33 centimeters
Let the Length of the rectangle be x centimeters
So, Perimeter of rectangle is given by formula : Perimeter = 2 × (Length + Width)
⇒ Perimeter = 2 × (x + 33)
⇒ Perimeter = 2x + 66
Now, The perimeter of the rectangle is at least 776 centimeters
⇒ Perimeter > 2x + 66
⇒ 776 > 2x + 66
⇒ 2x < 710
⇒ x < 355
So, The length of the rectangle must be less than 355 cm
⇒ Area of the rectangle < 355 × 33
⇒ Area of the rectangle < 11715 cm²

Given:
The quadratic equation is :
[tex]16x^2-20x-6=0[/tex]
To find:
The quadratic formula for the given equation after substituting the values.
Solution:
If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is:
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
We have,
[tex]16x^2-20x-6=0[/tex]
In this equation, [tex]a=16,b=-20,c=-6[/tex].
Substituting [tex]a=16,b=-20,c=-6[/tex] in the above formula, we get
[tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex]
Therefore, the required quadratic formula for the given equation after substituting the values is [tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex].

Solve for x
Answer:
x = 22
Step-by-step explanation:
6x + 48 = 180
6x = 132
X = 22
Please help with this word problem!
Answer:
a)
x = (158-112) / 1x
or 158-112 / x
b) 112+ 23 /158-23 = x
or if you want x to be the same value as the first part then you could write
112+x / 158-x = 135/135
or revise as an equality
23 ≤ 112 < 158
112 + 23 = 158
112 + x = 158
Step-by-step explanation:
Tailwind speed
x = 158-112 / 2
x = 46/2
x = 23 knots
Speed
x = 112 + 23 / 158-23
x = 135 / 135 m/h = same speed as stated in question.

If the angle of a sector measures 45° what fraction of the circle is the sector
The fraction of the circle measured by a sector which subtends an angle; 45° is; 1/8 (one-eighth).
It has been established from circle geometry that the angle subtended at a point is 360°.
On this note, the algebraic sum of angles in a circle is; 360°.In essence, a sector which measures 45° is only 1/8 of the circle.
45/360 = 1/8.Read more on sectors and circles;

A dessert of both yogurt and idiots were together in the ratio of 1:4 the idiot had 45 said LISA (lol)
Answer:
11.25
Step-by-step explanation:
Ratio of yogurt : ratio of idiot = 1 : 4
Idiot had 45
Yogurt = x
Ratio of yogurt : ratio of idiot = x : 45
Equate the ratios
1 : 4 = x : 45
1/4 = x/45
Cross product
1 * 45 = 4 * x
45 = 4x
x = 45/4
x = 11.25
Yogurt = x = 11.25

Solving inequalities by multiplication and division
1. -8 < 8w
Answer:
w > -1
Step-by-step explanation:
Hello There!
We want to simplify this expression to be more specific we want to isolate the variable (w) using inverse operations
So we want to get rid of the 8 in 8w
8w is the same as 8 times w (multiplication)
The inverse of multiplication is division so to get rid of the 8 we want to divide by 8 but remember whatever we do to one side we want to do to the other side. So we divide each side by 8
-8/8 = - 1
8w/8=w
we're left with w > -1
[tex]\huge\text{Hey there!}[/tex]
[tex]\mathsf{-8 < 8w}[/tex]
[tex]\large\text{TURN/FLIP the given EQUATION around}[/tex]
