Answer:
length: 200
width: 65
Step-by-step explanation:
length: 3w + 5
width: w
perimeter = 2L + 2W
530 = 2(3w + 5) + 2w
530 = 6w + 10 + 2w
530 = 8w + 10
520 = 8w
w = 65
length: 3w + 5 = 3(65) + 5 = 200
width: w = 65

Answer:
36 and 27
Step-by-step explanation:
4+3=7
63/7=9
9x4=36
9x3=27
The altitude of the smaller triangle will be given as follows:
let the altitude of the smaller triangle be x
scale factor of small to large triangle is 3:5
but
scale factor=(length of small Δ)/(length of large Δ)
plugging in our values we get:
3/5=x/24
solving for x we get:
x=3/5×24
x=14.4 inches
Answer: 14.4 inches
Answer:
The third number in the sequence is 24.
Step-by-step explanation:
Sum of five consecutive numbers is 120.
Let the numbers be represented by x,x+1,x+2,x+3,x+4
So the relevant equation for the sum of the numbers is represented as:
x + (x+1) + (x+2) + (x+3) + (x+4) = 5x + (1+2+3+4) = 5x+10
=> 5x + 10 = 120
=> 5x = 120-10
=> 5x = 110
=> x= 110/5 = 22
So the 5 consecutive numbers are 22, 22+1, 22+2, 22+3 , 22+4
In other words the required numbers are 22,23,24,25,26
The third number in the sequence is 24.
