Answer:

Step-by-step explanation:

We have a triangle 45° - 45° - 90°.

Sides are in the ratio 1 : 1 : √2 (<em>look at the picture</em>).

If $BC=12\sqrt2$ then $AB=(12\sqrt2)(\sqrt2)=(12)(2)=24$

Used $(\sqrt{a})(\sqrt{a})=a$

Find the perimeter of the figure to the nearest hundredth.

beks73 [17]

Answer:

28.87 inch

Step-by-step explanation:

The perimeter of a figure is the sum of the length of the boundary sides of the figure surrounding it.

For the above figure the perimeter is the sum of the three sides of the rectangle and circumference of the semicircle.

Diameter of the semicircle forming in the figure is 5 inch(given)

Circumference of the semicircle forming in the figure = $\pi r$

$3.14*2.5= 7.85 inch$ : $\pi =22/7=3.14$

The perimeter of the above given figure = $5 inch+7inch+7inch+7.85 =26.87 inch$

HELP PLEASE

let's first off convert the mixed fractions to "improper" and then proceed,

$\bf \stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}}\\\\ -------------------------------\\\\ \cfrac{\quad \frac{7}{2}pages\quad }{\frac{3}{4}hour}\implies \cfrac{7}{2}\cdot \cfrac{4}{3}\implies \cfrac{28}{6}\implies \stackrel{simplified}{\cfrac{14}{3}}\cfrac{pages}{hour}$
