Answer:
t = 45d
Step-by-step explanation:
Number of days = d
Number of minutes = t
Number of minutes per day = 45 minutes
Total number of minutes of practice after d number of days will be :
t = number of minutes per days * Number of days
t = 45 * d
t = 45d
Answer:
The measure of C is 75 degrees
Step-by-step explanation:
Since ABC is isosceles, we know that C is equal to B. Therefore, we can add all the angles together and set equal to 180 to find the value of x.
A + B + C = 180
x + 5 + 3x + 3x = 180
7x + 5 = 180
7x = 175
x = 25
Now we can plug in the value of x into 3x to find C.
C = 3x
C = 3(25)
C = 75
Answer:
454
Step-by-step explanation:
set up a system of equation
let y be the number of students
let x be the number of adults
because there are twice the amount of students attended as adults, we can use y=2x as one equation
the other equation will be 6.5y+9x=4972 because this represents the total amount of money
plug 2x for y : 6.5(2x)+9x=4972 : x=226
plug 226 in for the first equation : y=2(226) : y=452

Answer:
The minimum payment should she have is $ 6546.035
Step-by-step explanation:
Given as ;
Amount credit card balance = $12,300
The rate of interest = 13.45 %
The time period is 5 years
Let The principal be P
Now,
Amount = Principal ×
Or , $12,300 = p ×
Or, $12,300 = p ×
∴ p =
Or, P = $ 6546.035
Hence The minimum payment should she have is $ 6546.035 Answer
