For solving this question we will have to make use of a formula that will help us find out the area of any rectangle.

The formula states that the area of a rectangle is the product of it's length and it's breadth (or width).

Therefore as per this formula, the area of a rectangle can be written as:

Area = Length x Breadth

Now, we can use this formula to solve our question. The given rectangle is 25 inches long and 13 inches wide. Thus, the area of this rectangle will be:

Area = 25 inches x 13 inches = 325 squared inches

Round 0.5289 to the nearest thousandth.

Anit [1.1K]

Answer:

0.5289 to the nearest thousandth is 0.529.

Step-by-step explanation: If a number is less than 5, round down, but if a number is 5 or more, round up. The digit after the thousandths place is the digit we should look at to answer the question and it is 9, so we round up from 0.528 or 0.529. So, the answer is 0.529.

Find The art length of a sector with an area of 8 square units.

frez [133]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta \pi r^2}{360}\quad 
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad degrees\\
------\\
A=8\\
r=4
\end{cases}\implies 8=\cfrac{\theta \pi 4^2}{360}\implies \cfrac{8\cdot 360}{4^2\pi }=\theta 
\\\\\\
\cfrac{2880}{16\pi }=\theta \implies \boxed{\cfrac{180}{\pi }=\theta }\\\\
-------------------------------\\\\$

$\bf \textit{arc's length}\\\\
s=\cfrac{\theta \pi r}{180}\quad 
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad degrees\\
------\\
\theta =\frac{180}{\pi }\\
r=4
\end{cases}\implies s=\cfrac{\frac{180}{\underline{\pi} }\underline{\pi} \cdot 4}{180}\implies s=\cfrac{\underline{180}\cdot 4}{\underline{180}}
\\\\\\
\boxed{s=4}$

if you do a quick calculation on what that angle is, you'll notice that it is exactly 1 radian, and an angle of 1 radian, has an arc that is the same length as its radius.

that's pretty much what one-radian stands for, an angle, whose arc is the same length as its radius.

Answer:

Step-by-step explanation:

(-3/4)x + 9 = (-1/2)x + 8

9 - 8 = (-1/2)x + (3/4)x

1 = (1/4)x

x = 4

y = (-3/4)4 + 9

y = -3 + 9

y = 6
