46 out of 200 dogs are short haired breeds. What percent of dogs are not short haired breeds

Ivahew [28]

Hi!

46 out of 200 are short haired, which means that 200 - 46 = 154 out of 200 are not short haired. In percentages, that is:

154/200 = 77/100 = 77%

Hope this helps!

Find f if f′(x)=2x−3/x^4, x>0 and f(1)=2.

slavikrds [6]

$f'(x)=2x-\dfrac3{x^4}$
$\displaystyle\int f'(x)\,\mathrm dx=\int\left(2x-\frac3{x^4}\right)\,\mathrm dx$
$f(x)=x^2+\dfrac1{x^3}+C$

Given that $f(1)=2$ , we get

$2=1^2+\dfrac1{1^3}+C$
$2=2+C$
$\implies C=2$

so that

$f(x)=x^2+\dfrac1{x^3}$

Check my answer? The two triangles are similar. What is the value of x? 5.

Nikolay [14]

20/28 = 3x / (4x + 2)

84x = 20(4x + 2)
84x - 80x = 40
4x = 40
x = 10

so the 2 lines are equal to 30 and 42

A circle has a diameter of 22 cm. What is its circumference?

charle [14.2K]

Answer:

$\boxed {\tt 69.08 \ centimeters}$

Step-by-step explanation:

The circumference of a circle can be found using the following formula:

$c= \pi d$

where d is the diameter. We know the diameter of the circle is 22 centimeters. Substitute the value in for d.

$d= 22 \ cm$

$c= \pi* 22 \ cm$

We also know we are using 3.14 for pi. Substitute it in for pi.

$c= 3.14 * 22 \ cm$

Multiply.

$c=69.08 \ cm$

The circumference of the circle is 69.08 centimeters.
