Someone help me find the answer to this

The diameter of the plate is 12, and the formula for finding circumference is diameter times pie. so you multiply pie (or 3.14 if you aren't using a calculator) times 12 and it should give you 37.6991. rounded to the nearest tenth, that's 37.7, hope I helped!

If the legs of a right triangle are x, (2x - 1) and its hypotenuse is (2x + 1), what is the value of x?​
Ber [7]

Answer:

x=8

Step-by-step explanation:

(2x + 1)² = x² + (2x - 1)² = x² + (2x - 1)(2x - 1)

(2x + 1)(2x + 1) = x² + 4x²-2x-2x+1

4x²+2x+2x+1 = 5x²-4x+1

4x²+4x+1 = 5x²-4x+1

0= 5x²-4x²-4x-4x+1-1

0= x²-8x

x²-8x=0

x²=8x

x=8

The sum of three numbers is 3068.Two of the numbers are 1266 and 1755,find the third number<br><br>​
ratelena [41]

Answer:

The third number is 47.

Step-by-step explanation:

The sum of three numbers is 3068 - this can be expressed mathematically as:

\displaystyle{x + y + z = 3068}

Given that two of the numbers are 1266 and 1755 (in order) then substitute x = 1266 and y = 1755:

\displaystyle{1266 + 1755 + z = 3068}

Find the third number - solve for z-variable:

\displaystyle{3021 + z = 3068}\\\\\displaystyle{z = 3068-3021}\\\\\displaystyle{z = 47}

Therefore, the third number is 47.

Alvin takes pictures with his smartphone. Of the pictures 5/6 are animals. 3/4 of the animals are dogs. What fraction of the pic
ollegr [7]

Answer:

\dfrac{5}{8}

Step-by-step explanation:

Alvin takes pictures with his smartphone.

Of the pictures \frac{5}{6} are animals.

\frac{3}{4} of the animals are dogs.

To find which fraction of all pictures are pictures with dogs, you can simply multiply two fractions:

\dfrac{5}{6} \times \dfrac{3}{4} =\dfrac{15}{24} =\dfrac{5}{8}

<u>Another way</u> to solve this question:

Let the number of all pictures be 24 (divisible by both 4 and 6).

Then the number of pictures with animals is

\dfrac{5}{6} \times 24=5\times 4=20

and the number of pictures with dogs is

\dfrac{3}{4} \times 20=3\times 15

Hence, the fraction of pictures with dogs of all pictures is

\dfrac{15}{24}=\dfrac{5}{8}

People in Spaceland live in 8 space stations, and travel between the stations in tubes.Every pair of stations is connected by tw
NeTakaya

Based on the way these stations are connected, we can infer that there are <u>56 tubes. </u>

<h3>Number of tubes in Spaceland </h3>

Each pair of stations have 2 tubes. This means that every station is connected to each of the others.

We can therefore infer that each station has 7 tubes to the other stations.

The total number of tubes would therefore be:

= Number of stations x Number of tubes per station

= 8 x 7

= 56 tubes

In conclusion, there are 56 tubes.
