Answer:
5.9 × 10⁻¹⁶
Step-by-step explanation:
To solve this, you need to convert one of the two numbers to the same power of ten as the other. We can do that by multiplying the first number by 10:
6.7 × 10⁻¹⁶ - 8.2 × 10⁻¹⁷
= 67× 10⁻¹⁷ - 8.2 × 10⁻¹⁷
= (67 - 8.2) × 10⁻¹⁷
= 58.8 × 10⁻¹⁷
= 5.9 × 10⁻¹⁶
Note that we're rounding to the nearest tenth, as the original numbers given were as well.

Answer:
1st part is 958
2nd part is 1024
Step-by-step explanation:
Answer:
a. 958 inches
b. 1024 inches
Step-by-step explanation:
a. The perimeter is 2(234+245) = 958 inches, by the formula of the perimeter of a rectangle.
b. This will increase the perimeter by 2 * 33 = 66 inches (because we're increasing in one dimension), so the answer is 958 + 66 = 1024 inches.

Answer:
The second option from the left
Step-by-step explanation:
The right answer is the second option because if we follow the pattern through we will get the following...
[tex]y =2(4)^{x} \\y = 2(4)^{0} = 2(1) = 2\\y = 2(4)^{1} = 2(4) = 8\\y = 2(4)^{2} = 2(16) = 32\\y = 2(4)^{3} = 2(64) = 128[/tex]
From this we know the pattern must be 2, 8, 32, 128

B)describe the two dimensional figure cross section that results from slicing the cylinder number 6 with a vertical cross-section
PLEASE HELP QUICK
Answer:
What is the two dimensional shape that is created when the shape provided is sliced horizontally? Explanation: A horizontal cut is a side to side cut. This shape is a right rectangular pyramid, which has a base of a rectangle and sides in the shape of triangles; thus, a horizontal cut would make a rectangle.

The equation p = −5x2 + 100x − 250 models the profit p in dollars from selling pizza, where x is the price per pizza in dollars. What is the highest price you can charge per pizza to profit $100?
The highest price per pizza in a profit of $100 is approximately $15.48
The profit equation is given by:
p = -5 [tex]x^2[/tex] + 100x - 250
Substitute p = 100 and solve for "x":
100 = -5 [tex]x^2[/tex]+ 100x - 250
To solve this quadratic equation, it can be rearranged it to standard form [tex](ax^2 + bx + c = 0)[/tex]
[tex]5x^2- 100x + 350 = 0[/tex]
Now, we can solve the quadratic equation using the quadratic formula:
[tex]x = \dfrac{(-b\pm \sqrt ({b^2 - 4ac)}}{2a}[/tex]
In our equation, a = 5, b = -100, and c = 350. Substitute these values into the formula:
x =[tex]\frac{(\sqrt{(-100)^2 - 4 \times 5 \times 350}}{2\times5}[/tex]
x= [tex]\dfrac{{100 \pm\sqrt{3000}}}{10}[/tex]
Thus, the two possible solutions for "x":
[tex]x_1[/tex] =[tex]\dfrac{100 + \sqrt{3000}}{10}[/tex]
[tex]x_2[/tex] =[tex]\dfrac{100 - \sqrt{3000}}{10}[/tex]
Calculating the values:
[tex]x_1[/tex]≈ 15.48
[tex]x_2[/tex] ≈ 4.23
The highest price per pizza that results in a profit of $100 is approximately $15.48 (rounded to two decimal places).

Answer:
[tex]\frac{-24p + 5}{30p}[/tex]
Step-by-step explanation:
Did you mean to add the terms. You can only solve equations or inequalities and this is an expression. Assuming you are to add the terms, then the lowest common denominator is 30p
So, [tex]\frac{-2(10)}{3p(10)} + \frac{6p}{5(6p)} - \frac{30p}{30p} + \frac{5(5)}{6p(5)}[/tex]

Decide whether n = 9 is a solution to
the equation 2+n=7. Write yes or no
Answer:
No. The answer would be n=5

[tex][Kindly\ refer\ the\ attachment.]\\We\ are\ given\ that,\\\triangle ABC\ is\ a\ right-triangle\ and\ has\ it's\ legs\ x\ and\ z.\\It's\ altitude\ CD\ separates\ it\ into\ two\ triangles:\\\triangle BCD\ and\ \triangle ADC,\ both\ of\ which\ are\ right-triangles.\\Now,\\The\ Pythagoras\ Theorem\ tells\ us\ that:\\'The\ sum\ of\ squares\ of\ both\ the\ legs\ is\ equal\ to\ the\ square\ of\ the\\ hypotenuse'.\\Here,\\Lets\ consider\ three\ triangles\ separately.\\[/tex]
[tex]In\ \triangle ADC\ right\ angle\ is\ at\ \angle ADC.\\Hence,\\AC\ is\ the\ hypotenuse, and\ AD\ and\ DC\ are\ it's\ legs.\\Hence,\\AD^2+DC^2=AC^2\\Or,\\9^2+y^2=x^2\\\\Lets\ take\ the\ above\ equation\ as\ E_1.[/tex]
[tex]In\ \triangle BDC\ right\ angle\ is\ at\ \angle BDC.\\Hence,\\BC\ is\ the\ hypotenuse, and\ DC\ and\ DB\ are\ it's\ legs.\\Hence,\\DC^2+DB^2=BC^2\\Or,\\21^2+y^2=z^2\\Lets\ take\ the\ above\ equation\ as\ E_2.[/tex]

6(y + 6) = 3y - 33 solve
Answer:
y=-23
Let's solve your equation step-by-step:
6(y+6)=3y−33
Step 1: Simplify both sides of the equation
6(y+6)=3y−33
(6)(y)+(6)(6)=3y+−33(Distribute)
6y+36=3y+−33
6y+36=3y−33
Step 2: Subtract 3y from both sides
6y+36−3y=3y−33−3y
3y+36=−33
Step 3: Subtract 36 from both sides
3y+36−36=−33−36
3y=−69
Step 4: Divide both sides by 3.
3y/3=−69/3
y=−23
Answer:
y=−23
