Answer:

8 inches

Step-by-step explanation:

Area of a triangle = 1/2 (b) (h)

so let's plug them in.

1/2( (10) (h)

now let's plug in 8

1/2 (10) (8)

10 times 8 equals 80

now

dividing it by 1/2 equals 40

therefore

it's the height is 8 inches

Answer:

x=10

Step-by-step explanation:

x-2(12*1/2)=2(4-2x)+20

x-2(6)=8-4x+20

x-12=28-4x

3x-12=28

3x=30

x=10

The area of a 2D form is the amount of space within its perimeter. The area of the field in square kilometres is 45,000.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

Given that the rectangular field is 300meters long and 150 meters wide. Therefore, the area of the field in square kilometres is,

Area = Length x Width

        = 300 meter x 150 meter

        = 45,000 meter²

Hence, the area of the field in square kilometres is 45,000.

Overall answer: 10 1/9 - 1 5/18x (Most simplified answer)

Step-by-step explanation:

First you have to do all the Distributive property which the answer would be:

2 1/2 - 1/2x + 3 1/9 + 8/9x + 1/6x - 5/18x + 2 14/18 + 1 13/18

Then you have to find the common demoninator which would be 18

After that you have to put them in the correct order since there is two different terms which would be:

2 9/18 + 3 2/18 + 2 14/18 + 1 13/18 - 9/18x + 16/18x + 3/18x - 5/18x

After that you solve the problem which in the end after solving both terms it ends up as..:

10 2/18 - 1 5/18x

and I think that is as simplified as you can go term wise.

I hope this helps and I hope I didn't make a mistake :D

Assumption: 178 wore black (that means some may wear gold + black aka as long as they wore abit of black, it's counted):

since there are 257 students and 34 wore both gold and black, and 178 wore black, the number of students who wore only black = 178 - 34 = 144

no of students who wore only gold = 257 - 144 - 34 = 79

Answer:

The length of other side of rectangle is 5 units.

Step-by-step explanation:

We are given:

Area of rectangle = 30 square units

Length of one side = 6 units

We need to find the length of other side.

The formula used is: [tex]Area \ of \ rectangle=Length \times Width[/tex]

Considering length = 6, we need to find width.

Putting values in formula and finding length of other side

[tex]Area \ of \ rectangle=Length \times Width\\30=6 \times Width\\Width=\frac{30}{6}\\Width=5 \ units[/tex]

So, Width= 5 units

The length of other side of rectangle is 5 units.
