Aleonysh [2.5K]3 years ago

Answer:

x=5

Step-by-step explanation:

First, let's understand logarithms.

When there is no base given, like in this problem's right side of the equation, the base is automatically 10.

So, let's re-write that.

\frac{7}{x+2}=log_{10}x+5

Now, let's test a few of the numbers out. For brevity, I already know it's 3. Let's show you why.

\frac{7}{5+2}  =log_{10}(5+5)\\\frac{7}{7} =  log_{10}(10)\\1 = 1

Determine whether it is possible to form a triangle using each set of segments with the given measurements.
Gnesinka [82]
Are we talking about edges or the physical sides of the triangle?

If edges (corners / angles of the triangle), then no, because it doesn’t add up to 180. I don’t think the measurements of the sides matter, tho.

What is the simplified form of startroot startfraction 72 x superscript 16 baseline over 50 x superscript 36 baseline endfractio
ziro4ka [17]

The simplified form of the given equation is =\frac{6}{5x^{10}}

We have given that,

\sqrt{\frac{72x^{16}}{50x^{36} }

Apparently, you want to simplify the given equation,

\sqrt{\frac{72x^{16}}{50x^{36} }

 

The applicable rules of exponents are,

<h3>What is the exponent rule?</h3>

 (a^b)(a^c) = a^(b+c)

 1/a^b = a^(-b)

 (a^b)^c = a^(bc)

So the expression simplifies as

 =\sqrt{\frac{72x^{16}}{50x^{36} }}\\\\=\frac{6}{5x^{10}}

Therefore the simplified form of the given equation is =\frac{6}{5x^{10}}

Bryan created a scale drawing of his rectangular bedroom. His drawing had dimensions of 6 inches by 8 inches. If the scale that
vlabodo [156]

Answer:

56 feet

Step-by-step explanation:

If 1 inch = 2 feet, we can first find the actual dimensions of his room by multiplying the number of inches by 2.

6(2)

= 12

8(2)

= 16

So, the actual dimensions of his room are 12 feet by 16 feet.

To find the perimeter, use the perimeter formula, P = 2l + 2w.

Plug in the length and width:

P = 2l + 2w

P = 2(12) + 2(16)

P = 24 + 32

P = 56

So, the perimeter of his actual room is 56 feet.

23. The letters of the alphabet are written on
Alla [95]

Answer:

21/676

Step-by-step explanation:

The total number of letters of the alphabet will be the total outcome which is 26 alphabets.

If consonant numbers are drawn out, the probability of drawing a consonant will be total consonants/total alphabets

Total consonants in the alphabet is 21.

Probability of drawing consonants = 21/26.

Since all the consonants are replaced before drawing a Z, our total outcome will not change i.e it will still be 26.

Probability of drawing a letter Z will be 1/26.

Therefore, the probability of drawing a consonant,replacing it, and then drawing a Z will be;

21/26×1/26

= 21/676
