Answer:180

Step-by-step explanation:

you start by finding the prime factorization of the number

5=1*5

9=3*3

12=2*2*3

the shortest way to find the factors is to find is most of them like example, at max, there are 2 two's, 2 three's and 1 five then you multiply them all together

4*9*5=180 and that's the answer

the perimeter of a field has a perimeter of 270 feet and the length is 35 feet longer than the width. Write and graph the system
Stells [14]

Answer:

So I don't know the equation but I know the answer.

Length: 170 ft.

Width: 100 ft.

Step-by-step explanation:

The perimeter (The length all around) is 270. You do the perimeter divided by two and add 35, because we know they are almost equal except for one side is 35 ft. longer, That is your length. You the take the perimeter minus the length to get the width.

Equationish: P÷2= x+35= y -> P-y=w

Or: 270÷2= 135+35=170 -> 270-170= 100ft.

in the diagram, a building casts a 35-ft shadow and a flagpole casts a 10-ft shadow. if the flagpole is 22tall, how tall is the
8_murik_8 [283]

Let, the height of the building be x ft.

Given the building casts 35ft shadow.

The height of the flagpole given which is 22ft and casts a shadow of 10ft.

Now to find the height of the building we have to equate the ratio of height and shadow of the building and the flagpole.

So we can write,

x/35 = 22/10

To find x, we have to get rid of 35 from the left side and have to move it to right side. As 35 is divided there, we will multiply 35 to both sides.

(x/35)× 35 = (22/10)×35

x = (22×35)/10

x = 770/10

x = 77

So, the height of the building is 77 ft which is the required answer here.
