Answer:
4 ft
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
9 = 1/2 (4.5)h
9 =2.25 h
Divide each side by 2.25
9/2.25 = 2.25h/2.25
4 =h
Answer:
x > 3
Step-by-step explanation:
You have the following inequality:
In order to obtain the solution for x, you first apply distribution property in the left term of the inequality:
Next, you sum 2x on both sides, and you subtract 28 on both sides too:
(where you have simplifies similar terms)
Finally, you divide the inequality for -6, but you take into account that the inequality symbol change (because the operation with a negative term):
hence, the solution to the inequality is x > 3
(2 3/4) / (1/2) = x / 1.....2 3/4 miles to 1/2 hr = x miles to 1 hr
(11/4) / (1/2) = x/1
cross multiply
(1/2)(x) = (11/4)(1)
1/2x = 11/4
x = (11/4) / (1/2)
x = 11/4 * 2/1
x = 22/4
x = 5 1/2 <=== she jogged 5 1/2 miles per hr
