Answer:
Fred = 26, Natalie = 15
Step-by-step explanation:
N + F= 41 // N = 41 - F (eqn 1)
4N + F = 86 (eqn 2)
sub eqn 1 into eqn 2
4(41 - F) + F = 86
164 - 4F + F = 86
-3F = - 78
F = 26
sub F = 26 into eqn 1
N = 41 - F
N = 41 - 26
N = 15
Since BC is the hypotenuse...
α = 12
c = 13
Hence..
13² = 12² + ß²
ß = √(13² - 12²)
= √(169 - 144)
= √25
= 5
Hence, AB = 5
I hope this helps!
You can either express the decrease that happened in the account savings by integers. To do this you simply subtract 55$ from the initial amount in the account. This is expressed as:
initial amount - 55$
or, you can express the decrease in the form of percentage by calculating how much is 55$ from the total amount. This is expressed as:
(5/initial amount) x 100
Answer:
Irrational
Step-by-step explanation:
The number is irrational because when you convert it to decimal form, you get 276.4601... a repeating decimal that goes on and on.
B because the sum of 2 sides must be GREATER than the 3rd side
