Answer:
with discount+tax= $23.15
Step-by-step explanation:
board game is 25
discount: 15%
tax: 7.5%
discount means you take off that amount
tax means you add that amount
discount: 15% off
tax: +7.5%
to find 15% of 25 multiply 25 by 15% (15/100=0.15)
25*0.15
= 3.75
then subtract that from 25
25-3.75
=21.25
tax:
0.075*25
=1.875
~1.9
21.25+1.9
=23.15
Not unless the digits in each period are also in the same order. That is, the digit in each PLACE must be the same.
Answer:
Step-by-step explanation:
Let the no of cars be x and no of buses be y.
x + y = 60 -> y = 60 - x
6x + 30y = 600
with the available equations let us calculate the values of x and y.
6x + 30 * (60-x) = 600
6x + 1800 - 30x = 600
24x = 1200
x cars = 50
y buses = 10
maximum profit = 50 * 2.5 + 10 * 7.5 = $200

Answer:
43.638 cubic meters
Step-by-step explanation:
The triangular prism has 5 faces - 3 rectangular and 2 congruent triangular. Calculate the area of each face then add them together to find the surface area.
The triangles are 5.3 by 1.26 so the area of the two is 6.678.
The largest rectangle face is 5.3 by 3.3 so the area is 5.3*3.3 = 17.49.
The side rectangle face that is 3.3 by 3.6 so the area is 3.3*3.6 = 11.88.
The side rectangle face that is 2.3 by 3.3 so the area is 2.3*3.3 = 7.59.
Add all the areas together.
6.678 + 17.49 + 11.88 + 7.59 = 43. 638
