Josue broke a cell sample into 12 batches, each weighing 6.9 x 10 ^-10
Klio2033 [76]

Using proportions, it is found that the original sample weighed 8.28 \times 10^{-9} grams.

  • This question is solved by <em>proportions</em>, using a rule of three.
  • The weight of 1 batch, in grams, is of 6.9 \times 10^{-10}. How much do the sample of 12 batches weigh?

The rule of three is:

1 batch - 6.9 \times 10^{-10} grams.

12 batches - x grams

Applying cross multiplication:

x = 12 \times 6.9 \times 10^{-10} = 82.8 \times 10^{-10}

Applying scientific notation:

8.28 \times 10^{-9}

The original sample weighed 8.28 \times 10^{-9} grams.

US<br> Find the value of x.<br> 80<br> 93<br> 112<br> y<br> Z<br> x = [?]
Elenna [48]

Answer:

x = 74°

Step-by-step explanation:

The diagram shown in this question, is a Quadrilateral inscribed in a circle

It is important to note that

The sum of opposite angles in a Quadrilateral = 180°

93° + z = 180°

z = 180° - 93°

z = 87°

In a cyclic quadrilateral,

Intercepted angle = 1/2(Intercepted arc)

Intercepted angle = 93°

Intercepted arc = x + 112°

Hence,

93° = 1/2(x + 112)°

93° × 2 = x + 112°

186° = x + 112°

x = 186° - 112°

x = 74°

One leg of a right triangle has a length of 7 m. the other sides have lengths that are consecutive integers. find these lengths
andreyandreev [35.5K]
Let's make an equation based off of the pythagorean theorem.
7²+x²=(x+1)²
Since the diagonal is the biggest of the three lengths, the diagonal is the bigger even number. Since they are consecutive, they are one away. Let's distribute.
49+x²=x²+2x+1; let's subtract 1 from both sides.
48+x²=x²+2x; lets subtract x² from both sides.
48=2x; let's divide.
48÷2=24=x
So, since smaller integer is 24, the bigger one is 25. Let's make sure this makes sense.
7²+24²=25²
49+576=625
625=625

So, the missing lengths are 24 and 25.
