Answer:
Base = x = 18ft
Height = x - 4 = 14ft
Step-by-step explanation:
The formula for the area of A the triangle is given by the following equation:
1) A = (base * heigth)/(2)
From this problem, we know that
base = x and that the height is 4ft less than the base, so height = base - 4 = x - 4.
We also know that the area is 126ft², so A = 126 ft². Now we can replace these informations in equation 1).
126 = (x(x-4))/2
x² - 4x = 252
x² -4x - 252 = 0
The roots of this equation are x = 18 or x = -14. But we know that a triangle cannot have negative dimensions, so we use x = 18.
The base is x, so base = 18ft.
Height is 4ft less than the base, so height equals 18-4 = 14ft
Hello!
We have been given enough information to solve this question!
We know that the length of the rectangle is 2.5, and we also know how to find the area:
A = l × w
But we don't need the area, we need to find the width of the rectangle! You see, we had to multiply the length by the width to find the area.
Now, to find the width, we must flip the problem around and use the opposite of multiplication, which is division.
W = a ÷ l
W = 10 ÷ 2.5
W = 4
Therefore, the width of the rectangle is 4.
This would be so easy for you to solve, in about 3 minutes with a calculator.
A fraction means division ... (the top number) divided by (the bottom number).
Take the fraction part of each choice, do the division for each one,
and see which one gives you 0.4545... repeating.
A). 227/500 = 0.454 That's not 0.45 repeating.
B). 9/20 = 0.45 That's not 0.45 repeating.
C). 5/11 = 0.4545... THAT's 0.4545... repeating !
D). 9/2 = 4.5 That's not 0.45 repeating.
Answer:
60
Step-by-step explanation:
5 x 4 x 3=60
Answer:
let integers be x,2x, 3x respectively
x+2x+3x= 267
6x= 267
x=267/6= 44.5
2x= 44.5*2= 89
3x= 44.5*3= 133.5
largest integer = 133.5
hope it helps
