A) 0 represents the surface of the pool.
B) The height of the pool is 10 above the pool surface
C) It should be -3 since it is going down so it is going to be a negative number and it is also below the pool's surface.
Answer:
A
Step-by-step explanation:
112/0.8 = 140
Answer:
A and C
Step-by-step explanation:
Let Triangle ABC is a right angle traingle.
From Option A
AB= 24, BC= 26 and AC=10
By Pythagorean Triplet
(AB)^2 + (AC)^2 = (24)^2 + (10)^2
= 576+100
(AB)^2 + (AC)^2 = 676 ---------------- (I)
(BC)^2 = 26^2 = 676 -------------------(ii)
From (I) and (ii)
(BC)^2 = (AB)^2 + (AC)^2
Therefore, the sides 10,24 and 26 are the sides of the right angle triangle.
From Option C
AB= 18, BC= 30 and AC=24
By Pythagorean Triplet
(AB)^2 + (AC)^2 = (18)^2 + (24)^2
= 324+576
(AB)^2 + (AC)^2 = 900---------------- (I)
(BC)^2 = 30^2 = 900 -------------------(ii)
From (I) and (ii)
(BC)^2 = (AB)^2 + (AC)^2
Therefore, the sides 18, 24 and 30 are the sides of the right angle triangle.
Answer:
<em>3n; 2 nickels and 6 quarters</em>
Step-by-step explanation:
"Peggy had three times as many quarters as nickels."
Whatever number of nickels she has, the number of quarters is 3 times as many.
Since she has n nickels, she has 3 times n quarters.
The number of quarters is 3n.
A nickel is worth $0.05, so n nickels are worth 0.05n.
A quarter is worth $0.25, so 3n quarters are worth 0.25(3n).
0.05n + 0.25(3n) = 1.60
0.05n + 0.75n = 1.6
0.8n = 1.6
n = 2
She has 2 nickels.
3n = 3(2) = 6
She has 6 quarters.
