10^n = 10^3 times the square root of (10^31 / 0.001.)
What is n?

Answer:

0.27

0.18

0.21

60 packes because it costs 18 cents per pack and others are higher cost than that.

Step-by-step explanation:

5.49/20=027

10.97/60=0.18

18.95/90=0.21

so the best value will be box of 60 packs

Answer:

2x

Step-by-step explanation:

To combine like terms you must have a variable in both numbers. 3x-x is the same thing as 3x-1x. You combine and you get 2x. Hopefully that helps you out :)

Simplify the equation first:

8x+56=0

-56 on both sides

8x=-56

-56/8=-7

That's your answer: -7

Answer:

3,2.5, and 0.5

Step-by-step explanation:

3 + 2.5 = 5.5 and if you need the answer to be 6 then add 0.5

no way i can do math like that

Answer:

x=31

Step-by-step explanation:

2x+4x-6=180

6x=180+6

6x=186

x=31

Answer:

x = 31

Step-by-step explanation:

2x and 4x - 6 are alternate angles and supplementary, sum to 180°, then

2x + 4x - 6 = 180

6x - 6 = 180 ( add 6 to both sides )

6x = 186 ( divide both sides by 6 )

x = 31

Answer:

first find the length of trangel using

h^2=p^2+b^2

Equivalent expression for the missing side length of a rectangle is [tex]\sqrt{60} x[/tex]

The missing side length when x =3 is 23.2 inch

In a rectangle , opposite sides are equal . The vertex of rectangle is right angle . The diagonal of rectangle forms a right angle triangle.

Given the width of the triangle is 2x. The diagonal of triangle is 8x inches

Let 'L' be the length of the rectangle

To find out the expression for the length of the triangle use pythagorean theorem

hypotenuse ^2=length ^2 + width ^2

[tex](8x)^2=L^2+(2x)^2\\64x^2+4x^2+L^2\\64x^2-4x^2=L^2\\60x^2=L^2\\L =\sqrt{60x^2}\\ L=\sqrt{60}x[/tex]

An equivalent expression for the missing side length of a rectangle

[tex]\sqrt{60} x[/tex]

find the missing side length when x=3

Substitute 3 for x

[tex]L= \sqrt{60} x\\L =\sqrt{60}(3)\\L= 23.2 inch[/tex]

Equivalent expression for the missing side length of a rectangle is [tex]\sqrt{60} x[/tex]

Answer:

2 fancy shirts

5 plain

Step-by-step explanation:

2 fancy- 70$

5plain- 50$

50+70=120

Answer:

she bought 2 fancy shirts, and 5 plain shrits.

Step-by-step explanation:

$35×2=$70 (for the fancy shirts so she bought 2 fancy shirts)

Now, we have 5 shirts left that she bought so they must be plain shirts. to check, we would multiply $10×5=$50, then we would add $70(from the fancy shirts) and $50 (from the plain shirts) and get a total of $120.

I hope this helps!

Answer:

i = -7/12

Step-by-step explanation:

(-3/4 + 4/3) + i = 0

(-9/12 + 16/12) + i = 0

7/12 + i = 0

i = -7/12

Answer:

14 points.

Step-by-step explanation:

To solve this problem, let's make an equation.

Let x represent the unknown number, or the amount of points Andre scored.

We know that Noah scored 10 points.

Noah scored twice as many points as Diego, therefore Diego must've scored 5 points, because 5 * 2 = 10.

So, if Diego scored 9 points less than Andre, and we know that Diego scored 5 points, then the equation we are left with is

x - 9 = 5

To solve, just add 9 to both sides.

x - 9 + 9 = 5 + 9

We are left with:

x = 14

So, Andre scored 14 points.

Answer:

Option A i.e. 8, 3, -2, -7, ... is correct.

Step-by-step explanation:

Let us check the sequence given in option A

[tex]8, 3, -2, -7, . . .[/tex]

An arithmetic sequence has a constant difference '[tex]d[/tex]' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

determine the differences of all the adjacent terms of Arithmetic sequence

[tex]3-8=-5,\:\quad \:-2-3=-5,\:\quad \:-7-\left(-2\right)=-5[/tex]

The difference between all the adjacent terms is the same and equal to

[tex]d=-5[/tex]

Therefore, we conclude that the arithmetic sequence 8, 3, -2, -7, ... has a common difference -5.

Hence, option A i.e. 8, 3, -2, -7, ... is correct.

Answer:

8, 3, –2, –7, . . .

Answer:

3.14d > 50 cm

Step-by-step explanation:

Given that the circumference of a circle is approximately 3.14 times the length of its diameter

If the circumference is C and the length of the diameter is d then

C = 3.14d

If the circumference of a circle is more than 50 cm then

3.14d > 50

The  inequality can be used to find all possible diameter lengths, d,

d > 50/3.14

d > 15.92cm
