Answer:

\boxed{\sf \frac{15}{22} }

Step-by-step explanation:

The radius of the circle is 7 cm.

The two legs of the triangles are 7cm as well.

Area of a trinagle is ( base × height )/2.

\frac{7 \times 7}{2} =24.5

Multiply the value by 2 since there are two triangles.

24.5 \times 2 = 49

Calculate the area of the circle.

\pi r^2

The radius is given.

\pi (7)^2

Take \pi as \frac{22}{7}

49(\frac{22}{7} )

=154

Subtract the area of the two triangles from the area of the whole circle.

154-49=105

The area of the shaded part is 105 cm². The total area of the shape is 154cm².

\frac{105}{154} =\frac{15}{22}

Six times the amount of women that were at the banquet last year will be in attendance this year. The same amount of men will be
Rina8888 [55]

Answer:

m+6n

Step-by-step explanation:

Let number of men who attended last year=m

Let number of women who attended last year=n

This year, we expect Six times the amount of women attendance last year =6 X n = 6n

The same number of men, m will be expected this year

Therefore, Number of Expected Attendees

= Number of Men + (Six Times the Number of Women)

=m+6n

We can expect (m+6n) people to be in attendance this year.

A company manufactures skateboards. Each skateboard requires 1 6/7 hours of labor to assemble and 2 1/2 hours of labor to finish
Assoli18 [71]

Answer: The total cost will be $156.85.

Step-by-step explanation:

Since we have given that

Time taken by labor to assemble the each skateboard is given by

1\frac{6}{7}\ hours\\\\=\frac{13}{7}\ hours

Time taken by labor to finish and stain each skateboard is given by

2\frac{1}{2}\ hours\\\\=\frac{5}{2}\ hours

Cost of labour to the company per hour = $36.00

According to question,

We will use "Distributive Property":

a\times (b+c)=a\times b+a\times c

36(\frac{13}{7}+\frac{5}{2})\\\\=36\times \frac{13}{7}+36\times \frac{5}{2}\\\\=\frac{468}{7}+18\times 5\\\\=\frac{468}{7}+90\\\\=\frac{468+630}{7}\\\\=\frac{1098}{7}\\\\=\$156.85

Hence, the total cost will be $156.85.
