Rename 7/20 as a percent

igomit [66]

Step-by-Step Explanation:

a) Rename $\frac{7}{20}$ as a percent

$\frac{7}{20}\times 100\\\\=7\times 5\\\\=35\%$

b) Rename .245 as a percent

$.245\times 100\\\\=\frac{245}{1000}\times 100\\\\=24.5\%$

c) Rename 28% as a fraction and a decimal in simplest form

$28\%=\frac{28}{100}=\frac{7}{4}\text{ as a fraction}\\\\\frac{7}{4}=1.75\text{ as a decimal}$

d) Put .367,36.5%, $\frac{9}{25}$ in order least to greatest.

$\text{ First we put change all into percent form}\\\\.367\times 100=\frac{367}{1000}\times 100=36.7\%\\\\\frac{9}{25}\times 100=9\times 4=36\%$

Now, we have 36.7%, 36.5%, 36%

We have write it in ascending order i.e. least to greatest ,

Here it is,

36%, 36.5%, 36.7%

$\frac{9}{25},36.5\%\ and\ .367$

How do you implicitly differentiate: sqrt(xy)=x^2y+1

Furkat [3]

Implicit expression refers to equation that are not strictly expressed in terms of y and x separately. In this case, the derivative of expression
sqrt(xy)=x^2y+1 is

sqrt x * 0.5 y ^-0.5 dy + sqrt y * 0.5 x ^-0.5 dx= x^2 dy + 2xy dx
dy (x^2 - 0.5 (x/y) ^0.5) = dx (2xy - 0.5 (y/x)^0.5)
dy/dx = (2xy - 0.5 (y/x)^0.5) / (x^2 - 0.5 (x/y) ^0.5)

Using x as the variable, write a formula to find the perimeter of the figure. Use the formula to find the perimeter. a regular d

Mamont248 [21]

Answer:

c. 12x; 111 cm

Step-by-step explanation:

The regular dodecagon has 12 sides. Each side has a length of x=9.25 cm, and we know that the perimeter of the figure is the sum of the lengths of all the sides: Therefore, since we have 12 sides, the perimeter will be given by the product between the length of each side, x, and the number of sides, 12:

$p=12 \cdot x$
