Cost of 7 gallons=$24.50
Cost of 1 gallon=24.50/7=3.5
Cost of 15 gallons=15*3.5=52.5
Cost of 15 gallons will be $52.5
The total nom of code that can be used is equal to 5+3 = 8
The solution is in the following image
F=ma
where F=force
m=mass
a=acceleration
Here,
F=4300
a=3.3m/s2
m=F/a
=4300/3.3
=1303.03kg
Salesperson will make 6% of 1800
=(6/100)*1800
=108
Salesperson will make $108 in $1800 sales
The answer is in the image
30% of 420 are first year students
first year students = (30/100 )*420
=126 students
Student who are not in first year = 420-126
=294 students
Area of rectangle= L*b
here,
L=12.4 cm
b= 8.8 cm
A= L*b
= 12.4 * 8.8 = 109.12 cm^2
Cost before sale tax=$46.00
Cost after including tax=$48.76
Sale tax=$48.76-46.00
=$2.76
we know,
sale tax=((sales tax rate)/100) * cost before sale tax
2.76=((sales tax rate)/100) *46.00
sale tax rate=(2.76*100)/46
=276/46
=6%
There fore sales tax rate=6%
It will provide an instant answer!
