The circumference of a circle is 22 cm.
valkas [14]

\bf \: Circumference \:  of  \: a \:  circle = 2\pi \: r

\implies22 = 2 \times  \dfrac{22}{7}  r

\implies22 =  \dfrac{44}{7}  \times r

\implies \: r =  \dfrac{22 \times 7}{44}

\implies \boxed{ r =  \dfrac{7}{2} }

Now,

\bf \: Area \:  of  \: circle = \pi {r}^{2}

\rightarrow \:  \frac{22}{7}   \times  ({ \frac{7}{2}) }^{2}

\rightarrow \frac{22}{ \cancel7}  \times  \frac{ \cancel{49}}{4}

\rightarrow \: 22 \times  \frac{7}{4}

\rightarrow \: 11 \times  \frac{7}{2}

\rightarrow \frac{77}{2}

\rightarrow \: 38.5 \: cm {}^{2}

Area of rectangle = 38.5 cm².

Slope = -1/5

Step-by-step explanation:

(-5, -2)(5, -4)

Slope: \frac{y^{2}-y^{1}  }{x^{2}- x^{1} } = \frac{-4-(-2)}{5-(-5)} =\frac{-4+2}{5+5} =\frac{-2}{10}=-\frac{1}{5}

Tripp and Rico are two dogs. Tripp weighs exactly 35 pounds more than Rico. Together, they weigh exactly 49 pounds. How much doe
babymother [125]
Call the weights of the two dogs t and r.

We know that Tripp weights 35lbs more than Rico, or:
t=r+35

We also know that the total weight of both dogs is 49lbs.:
t+r=49

Now, by substitution:
(r+35)+r=49
2r+35=49
2r+35-35=49-35
2r=14
r=\frac{14}{2}
r=7
Rico weighs 7lbs.

Then:
t=r+35
t=7+35
t=42
Tripp weighs 42lbs.

To check our work:
t+r=49
42+7=49
49=49  CHECK!
