Answer:

319.5in

Step-by-step explanation:

First lets calculate the area of all the rectangles

2(6in * 15in) = 180in

The 2 is because there are two rectangles with the dimensions of 6in and 15in.

7.5in * 15in = 112.5in

112.5in + 180in = 292.5

Next lets calculate the area of the triangles.

4.5in * 6in / 2 = 13.5in

13.5 + 13.5 = 27in

292.5in + 27in = 319.5in

hope this helps!

What is f×e where e={1,2,13} and f={44,8,2}?

alexandr1967 [171]

Answer:

$f\times e=\{(1,44),(1,8),(1,2),(2,44),(2,8),(2,2),(13,44),(13,8),(13,2)\}$

Step-by-step explanation:

The Cartesian Product of two sets is all <u>pairs</u> in which the first element of each pair comes from the first set, and the second element comes from the second set.

$f\times e=\{(1,44),(1,8),(1,2),(2,44),(2,8),(2,2),(13,44),(13,8),(13,2)\}$

This was built using 1 from the first set paired with each number in the second set, then using 2 from the first set paired with each number in the second set, then 13 from the first set paired with each number in the second set.

A company can send a maximum of 40 workers to complete a

rewona [7]

Answer:

Step-by-step explanation:

For the sake of the problem, let's make female workers "x" and male workers "y".

x+y<40 This equation shows that the total number of workers has a max of 40.

30x+20y<1,000 This equation shows that the total cost the manager pays ($30 to each woman, $20 to each man) has a max of $1,000.

Now you can solve for x and y.

X+y<40

-y -y

X<-y+40

Substitute -y+40 in for X in the second equation

30(-y+40)+20y<1,000

-30y+1200+20y<1,000 Distribute

-10y+1,200<1,000 Combine like terms

-10y<-200 Subtract 1,200

y>20 Divide by -10; flip the sign

Since y>20, and y=male workers, you now know that the minimum

number of male workers he should send is 20

I need help please help!

Blababa [14]

Answer:

50.5 m^3

Step-by-step explanation:

Volume of pyramid = 1/3 × base area × height.

Height: 11
Base Dimensions: 4.3 and 3.2

Area of Base:

$4.3 * 3.2$
$13.76$

Next, we multiply 13.76 by 11.

13.76 × 11
151.36

Lastly, divide by 3 and round to nearest tenth.

151.36 ÷ 3
50.453333..
≈ 50.5

Therefore, the answer is 50.5 m^3
