7, to find the mean add up all the numbers and then subtract by the amount of Humber a you added.

For example, 1,3,8,10 added together is 22. We added four numbers together, so divide by 4. The mean of 1,3,8,10 is 5.5

Answer:

$8x-40y\geq 600$ and $x>0,y>0$

Step-by-step explanation:

The number of people is $x$ and the number of hours they are present in the space is $y$ .

Per person entry cost is $8.

Per hour cost of rent is $40.

They plan to earn a minimum of $600.

Donations by all the people entering the space is $8x$

Total cost of renting the space is $40y$ which will be subtracted from the total amount of donations.

The inequality that represents the situation is $8x-40y\geq 600$ and $x>0,y>0$ .

Tia cut a 4-meter 8 centimeter wire into 10 equal pieces Marta cut a 540-centimeter wire into 9 equal pieces how much longer is

Artyom0805 [142]

Answer:

12 centimeters

Step-by-step explanation:

First lets separate both wires.

Tia's wire is 408 centimeters long. This is because 1 meter = 100 centimeters. This meter will be cut into 10 equal pieces. To do that, simply divide 408 by 10.

408 / 10 = 48 centimeter long pieces

Marta's wire is 540 centimeters long. This meter will be cut into 9 equal pieces. Like before, we will divide 540 by 9.

540 / 9 = 60 centimeter long pieces

To conclude, one of Marta's wires are 12 centimeters longer than Tia's.

Find the area of this shape

chubhunter [2.5K]

Personally the easiest way for me is to first find the area of the rectangle and take away the missing triangles. So assuming it’s a rectangle we get (4+5)(3+2) = 45. Ok now we find the area of the triangles. 0.5(4)(3) = 6. Now we subtract that twice from our 45.
45-6-6 = 33. The answer is 33
