Answer:
The total amount paid for the shoe is $36.45
Step-by-step explanation:
In this question, we are asked to calculate the total amount to be paid for a shoe ordered online given the tax to be paid and the shipping cost.
The value of the sales tax = 6.5% of $30
This is mathematically equal to; 6.5/100 * 30 = $1.95
The shipping is 15% of the shoe price
Mathematically this is equal to 15/100 * 30 =
$4.5
The total amount paid for the shoe is thus; $30 + $1.95 + $4.5 = $36.45
A^2 + b^2 = c^2...where a and b r the legs and c is the hypotenuse
35^2 + b^2 = 37^2
1225 + b^2 = 1369
b^2 = 1369 - 1225
b^2 = 144...by taking the sqrt of both sides, this eliminates the ^2 on left
b = sqrt 144
b = 12...so ur other leg is 12 <==
I guess you want to find the values of x & y. If so:
7x+2y=24
8x+2y=30
1) multiply the 1st equation by (-1)==> -7x-2y=-24
2) Now add -7x-2y=-24 to 8x+2y=30 ==> x + 0y = 6 ==> x = 6
3) replace x by 6 in any of te two equation & you will find y= - 9
Answer:
135
E = - 14.5t + 135
Step-by-step explanation:
Given that, descent rate is constant ;
Elevation after 2 days = 106 m
Elevation after 6 days = 48 m
Let
Rate of elevation per day= x
Initial elevation = a
Hence,
a - 2x = 106 - - - (1)
a - 6x = 48 ___(2)
-2x + 6x = 106 - 48
4x = 58
x = 58/4
x = 14.5 meters per day
Hence, initial elevation :
a - 2(14.5) = 106
a - 29 = 106
a = 106 + 29
a = 135
Relationship between Rover's elevation, E and elapsed time, t
E = - 14.5t + 135
-14.5 = rate per day
