Use any method to add or subtract 5/7 {3/14+3/14}
OlgaM077 [116]

Answer:

15/49

Step-by-step explanation:

5/7 (3/14 + 3/14)

first combine like terms

3/14 + 3/14 = 6/14

then simplify by 2

6/14 to 3/7

now that both the term inside and outside have the same denominator, multiply

5/7 x 3/7 = 15/49

Help please ASAP !!!
Arisa [49]

For this case we have that by definition of trigonometric relations of rectangular triangles, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. So:

Sin (45) = \frac {leg} {h}

Where h is the hypotenuse.

\frac {\sqrt {2}} {2} = \frac {leg} {h}

We cleared h:

h = \frac {2leg} {\sqrt {2}}

We rationalize:

h = \frac {2leg} {\sqrt {2}} * \frac {\sqrt {2}} {\sqrt {2}}\\h = \frac {2 \sqrt {2} * leg} {2}\\h = \sqrt {2} * leg

Find the area of the figure. round your answer to the nearest hundredth
liraira [26]

Answer: 84.14

Step-by-step explanation:

Area of the rectangle is L*W=B*H

14*5=70

To find the area of the half circle we must use the formula pi r^2/2

r=radius

and the radius is 6 because we add 4 and 4 and need to get to 14

because the line below it is 14 and it is a rectangle so the lengths are the same.

Diameter=6

So radius =3

pi (3)^2/2=

9/2 pi + 70=

84.14
