3 x 4 = 12
12/12 - 1/3 ( so 4/12) = 8/12
8/12 - 1/4 ( so 2/12 as you only have 8/12 left) = 6/12
Answer = 6/12 = 1/2 or 50%
Answer:
The length of the altitude from the right angle to the hypotenuse of a right triangle is the <u>geometric</u> mean of the two segments that make the hypotenuse.
Answer: 21 eggs
Step-by-step explanation:
Charlie gathered 3 eggs from each of the three chickens so the total he gathered from chickns is:
= 3 * 3
= 9 eggs
From the 6 turkeys he got:
= 2 * 6
= 12 eggs
Eggs in total:
= 9 + 12
= 21 eggs
Answer:
20 m by 10 m
Step-by-step explanation:
let w be width and l be length , then
2(l + w) = 60 ( divide both sides by 2 )
l + w = 30 ( subtract w from both sides )
l = 30 - w → (1)
lw = 200 → (2)
Substitute l = 30 - w into (2)
w(30 - w) = 200 ← distribute parenthesis on left side
30w - w² = 200 ( subtract 200 from both sides )
30w - w² - 200 = 0 ( multiply through by - 1 )
w² - 30w + 200 = 0 ← in standard form
(w - 10)(w - 20) = 0 ← in factored form
Equate each factor to zero and solve for w
w - 10 = 0 ⇒ w = 10
w - 20 = 0 ⇒ w = 20
Substitute these values into (1)
l = 30 - 10 = 20
l = 30 - 20 = 10
dimensions of field is 20 m by 10 m
