1st week - Lost 3 pounds = +3 
2nd week - Gained 1 pound = -1    
3+13 = + 22       

So 22+3 = 25                 25-1 = 24 

So Tina lost 24 pounds in 13 weeks.

Find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)
laila [671]
\bf \textit{area of a circle}\\\\
A=\pi r^2\quad 
\begin{cases}
r=radius\\
-----\\
A=452.16
\end{cases}\implies 452.16=\pi r^2\implies \cfrac{452.16}{\pi }=r^2
\\\\\\
\boxed{\sqrt{\cfrac{452.16}{\pi }}=r}\\\\
-------------------------------\\\\
\textit{circumference of a circle}\\\\
C=2\pi r\qquad \qquad \implies C=2\pi \left( \boxed{\sqrt{\cfrac{452.16}{\pi }}} \right)

so, is just that product, recall to use "<span>3.1416 as the value of π".</span>

Malik stops at the grocery store to buy a bag of diapers and 2 cans of formula. He spends a total of $37. The next week he stops
Sedbober [7]

Answer:

Diapers costs $11 and formula is $13.

Step-by-step explanation:

Let's name diapers as A and formula as B.

Simply the equations:

1A + 2B = $37(1)

2A + 5B = $87(2)

Clear D from one equation.

A = $37 - 2B(1)

Replace D into the other equation.

2*($37 - 2B) + 5B = $87(2)

$74 - 4B + 5B = $87

$74 + B = $87

B = $87 - $74 = $13

Find A, now knowing B.

A = $37 - 2($13)

A = $37 - $26 = $11

1/3 of the dimensions means to divide the dimensions by 3. This is to figure out what 1/3 of the dimensions are.
Our length is 6, and our width is 9.
Let's divide our length first.
6/3 = 2.
Our length with 1/3 of it's original dimensions is 2.
Let's divide our width now.
9/3 = 3.
Our width with 1/3 of it's original dimensions is 3.
Our dimensions are 2 by 3.
Your answer is A.) 2 in. by 3 in.
