Someone please help ! The landlord of an apartment building needs to purchase enough digits to label all of the apartments from

100 through 125 on the first floor and 200 through 225 on the second floor. The digits can only be purchased in a package that contains one of each digit 0 through 9. How many packages must the landlord purchase?

Since 1 and 2 are used at least once in half of the apartments, and no other number is used this often, either 1 or 2 will be the most frequent digit used.

<span>Since all of the numbers of the form </span><span> appear but only 6 of the numbers </span><span> appear, 2 will be used less often than 1 and we should count the number of 1s to find the number of packages needed.</span>

100 through 125 requires 26 ones just for the hundreds place. 100 through 125 and 200 through 225 require the same number of ones for the tens and units places; that is, thirteen.

<span>So, there are </span><span> ones used. Therefore, the landlord must purchase </span><span> 52   packages.</span>

On a coordinate plane, a line goes through (negative 3, 0) and (0, negative 6).
shusha [124]

Answer:

B. (1,-8)

Step-by-step explanation:

Slope of the first one:

(-6-0)/(0--3) = -6/3 = -2

y = -2x - 6

3y + 30 = 6x

y + 10 = 2x

-2x - 6 + 10 = 2x

4 = 4x

x = 1

y = -2(1) - 6

y = -8

Need help with gem trip sequences <br> 36 points!!!!!!!!!
coldgirl [10]

Answer:

a_{n} = 8(-3)^{n-1}

Step-by-step explanation:

The n th term of a geometric sequence is

a_{n} = a(r)^{n-1}

where a is the first term and r the common ratio

Here a = 8 and r = - 24 ÷ 8 = - 3, thus

a_{n} = 8(-3)^{n-1}

what is the polynomial function of lowest degree with leading coefficient of 1 and roots 2 and 1 + square root2
Marta_Voda [28]
If the roots to such a polynomial are 2 and 1+\sqrt2, then we can write it as

(x-2)(x-(1+\sqrt2))

courtesy of the fundamental theorem of algebra. Now expanding yields

(x-2)(x-1-\sqrt2)=x^2-2x-(1+\sqrt2)x+2(1+\sqrt2)=x^2-(3+\sqrt2)x+2+2\sqrt2

which would be the correct answer, but clearly this option is not listed. Which is silly, because none of the offered solutions are *the* polynomial of lowest degree and leading coefficient 1.

So this makes me think you're expected to increase the multiplicity of one of the given roots, or you're expected to pull another root out of thin air. Judging by the choices, I think it's the latter, and that you're somehow supposed to know to use 1-\sqrt2 as a root. In this case, that would make our polynomial

(x-2)(x-(1+\sqrt2))(x-(1-\sqrt2))=x^3-4x^2+3x+2

so that the answer is (probably) the third choice.

Whoever originally wrote this question should reevaluate their word choice...

Which of the following graphs represents the solution set for 7(4x – 1 ) + 6x &gt; –279? PLEASE HELP
Luda [366]
First, solve the inequality:
7(4x - 1 ) + 6x \ \textgreater \  -279\\&#10;28x-7+6x\ \textgreater \ -279\\&#10;34x\ \textgreater \ -272\\&#10;x\ \textgreater \ -8
Since x is <u>greater than</u> -8, you have the arrow point up the graph towards the positive side starting at -8.
Since it's greater than but not equal to -8, the circle is open.

Thus your graph is D.

Use Euler’s Formula to find the missing number.<br> Edges: 37<br> Faces: 25<br> Vertices: ?
matrenka [14]

Answer:

Step-by-step explanation:

Comment

The formula that relates edges faces and vertices is  F + V = E + 2

Givens

Edges (E): 37

Faces (F) = 25

Vertices: x

Solution

25 + x = 37 + 2                Subtract 25 from both sides.

25-25 +x= 37 - 25 + 2    Combine

x = 12 + 2

x = 14

Answer: The vertices =<u> 14</u>
