Answer:
13
Step-by-step explanation:
Set Susan's present age as x, her age from 3 years ago as x-3, and her age in three years as 2(x-3)
Since her age in seven years = 2 times as old as she way 3 years ago, set up the equation:
x+7 = 2(x-3)
x+7 = 2x-6
x = 13
$1250
Use the formula i = prt
In this case, we don't know P or Principal amount
i = 400
r = .04 *found by diving 4/100*
n = 8
Set formula to solve for P like: P= i/r(n)
P=400/.04(8)
P= 400/.32
P = 1250
The output would depend on the input so relating this to the question, the input is the time (in minute) and the output is the amount of water left in the tank
We can give a letter 't' for the time, the input, and f(t) for the output
----------------------------------------------------------------------------------------------------------------
The original amount of water in the tank is 10450, so this will be the fixed constant.
The amount of water lost per minute is 270 so this will be the term that varies depends on the variable of time, we write this as 270t
The function is given f(t) = 10450 - 270t
--------------------------------------------------------------------------------------------------------------
Given, t = 10
f(10) = 10450 - 270(10)
f(10) = 7750 ml
Answer:
From given relation the value of β is 37.5°
Step-by-step explanation:
Given as :
α and β are two acute angles of right triangle
Acute angle have measure less than 90°
Now given as :
= 
Or, 
=
SO, 
= 
Or, 90° = + 
or, 90° = 
+ 4x
Or, 90° = 
So, x = 
= 15°
∴ = 
So, = sin
∴ The value of Ф_1 = = 37.5°
Similarly = 
So ,The value of Ф_2 = 
= 52.5°
∵ β 
α
So, As 37.5°52.5°
∴ β = 37.5°
Hence From given relation the value of β is 37.5° Answer
Answer:
2.00
Step-by-step explanation:
let the empty box be the variable n. n+0.34=2.34
subtract .34 from both sides
n=2.00
