Answer:

Step-by-step explanation:

First of all we have to use cos.

cos (30) is √3/2

so (7√3)/(√3/2)

7√3 * 2/√3 = 14√3/√3

(14√3 * √3 )/ 3

42/3 = 14

<u>I AM ASSUMING THIS QUESTION IS NON CALC.</u>

The answer should be 14.

A semicircle is attached to the side of a rectangle as shown.

laiz [17]

Answer:

$58.8\ mm^2$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of rectangle plus the area of semicircle

step 1

Find the area of rectangle

The area of rectangle is equal to

$A=bh$

where

$b=9\ mm\\h=3\ mm$

substitute

$A=(9)(3)=27\ mm^2$

step 2

Find the area of semicircle

The area of semicircle is equal to

$A=\frac{1}{2}\pi r^{2}$

we have

$r=9/2=4.5\ mm$ ---> the radius is half the diameter

$\pi =3.14$

substitute

$A=\frac{1}{2}(3.14) (4.5)^{2}$

$A=31.8\ mm^2$

step 3

Find the area of the figure

$A=27+31.8=58.8\ mm^2$

there are five boys and ten girls in mr johnsons gym class.the simplified ratio of boys to girls is 1/2. what does this ratio me

inn [45]

Answer:

This ratio means for every boy there are two girls.

There are twice as many girls as there are boys. Backwards, it's there are half as many boys as there are girl.

The simplified ratio is found by reducing the ratio to the lower terms.

5/10 = 1/2

Both sides on the unsimplified ratio are division by 5. When done, it became 1/2.
