An E. coli bacterium has a diameter of about 5×10^-7 meter. Write this measurement as a decimal in standard notation. Explain .

Archy [21]

5<span>×</span>10^-7 = 0.0000005
When 10 is to a negative power, you move the decimal to the left because the number is less than positive 1. Here 10 is to the power of -7, so you move the decimal (which is after/behind 5) to the left 7 times.

In math class the girl to boy ratio is 8 to 6 if there are 24 girls in the class , how many boys are there ?

Volgvan

Answer: The required number of boys in the class is 18.

Step-by-step explanation: Given that in math class, the girl to boy ratio is 8 to 6 and there are 24 girls in the class.

We are to find the number of boys in the class.

Let 8x and 6x represents the number of girls and boys in the class.

Then, according to the given information, we have

$8x=24\\\\\Rightarrow x=\dfrac{24}{8}\\\\\Rightarrow x=3.$

Therefore, the number of boys in the class is given by

$6x=6\times3=18.$

Thus, the required number of boys in the class is 18.

Please help if you can

Arisa [49]

Answer:

Option D

Step-by-step explanation:

Formula to be used,

Scale factor = $\frac{\text{Dimension of the image rectangle}}{\text{Dimension of the original}}$

By this formula,

$\frac{7}{2}=\frac{\text{Length of the dilated rectangle}}{\text{Length of the original rectangle}}$

$\frac{7}{2}=\frac{L}{22}$

L = $\frac{7\times 22}{2}$

= 77 inches

Similarly, width of the the dilated rectangle = $\frac{7}{2}\times 10$

= 35 inches

Perimeter of the new rectangle = 2(Length + width)

= 2(77 + 35)

= 224 inches

Option (D) will be the correct option.
