Answer:

Percentage of hits in English,French,Spanish and Japanese are 0.59%,0.16%,0.13% and 0.11% respectively.

Step-by-step explanation:

We have to find the percentage of hits for each version of the website.

The hits for the versions are

English = 4860

French = 1350

Spanish = 1080

Japanese = 900

<u>Total number of hits = 8190 hits.</u>

Percentage of hits = $\frac{number of hits of a version}{Total number of hits}$

Percentage of English = $\frac {4860}{8190}$

= 0.59 %

Percentage of French = $\frac {1350}{8190}$

= 0.16 %

Percentage of Spanish = $\frac{1080}{8190}$

= 0.13 %

Percentage of Japanese = $\frac{900}{8190}$

= 0.11 %

These are the required percentages.

Salsk061 [2.6K]

Answer:

<h3>The expression for the perimeter P is $P=\frac{784+h^2}{2h}$ feet.</h3><h3> Area=49=lx square feet ( here $x=\frac{h}{4}$ )</h3>

Step-by-step explanation:

Given that rectangle with height equals 4times width.

It can be written as

$h=4\times width$

Let x be the width of the given rectangle

Therefore $h=4\times x$

$h=4x$

$\frac{h}{4}=x$

Rewritting the above equation we get

$x=\frac{h}{4}$

<h3>To write an expression for the perimeter P of the given rectangle :</h3>

Also given that area of the rectangle is 49 square feet.

Area=49 square feet.

We know area of rectangle = lw square units.

<h3>Therefore area=49=lx square feet ( here area=49 and w= $x=\frac{h}{4}$ )</h3>

Rewritting we get

lx=49 square feet.

$l=\frac{49}{x}$

$=\frac{49}{\frac{h}{4}}$

$l=\frac{49\times 4}{h}$

<h3> $l=\frac{196}{h}$ feet</h3><h3>Perimeter P $=2(l+w)$ units </h3>

$P=2(\frac{196}{h}+\frac{h}{4})$

$P=\frac{2(196)}{h}+\frac{2(h)}{4}$

$=\frac{392}{h}+\frac{h}{2}$

$=\frac{392(2)+h^2}{2h}$

Who can solve this exercises pleaseeee i have a exam

Answer:

Step-by-step explanation:

1) Two angles supplementary. So sum of two angles is 180

One angle = x

Other angle = 2x

x + 2x = 180

3x = 180

x = 180/3 = 60

The angles are 60, 120

2)Two angles complementary. So sum of two angles is 90

one angle = x

Other angle = x + 20

x +x +20 = 90

2x + 20 = 90

2x = 90- 20

2x = 70

x = 70/2 = 35

The angles are 35,55

3) one angle =x

Other angle = 3x - 20

x + 3x - 20 = 120

4x = 120 + 20

4x = 140

x = 140/4 = 35

The angles are 35,85

5) x + 4x -20 = 180

5x = 180 + 20

5x = 200

x = 200/5 = 40

x = 40

6) This sum is not clear only half is visible
