Answer:
$64.36
Step-by-step explanation:
12% percent of %79.70 is %9.56 and there is a 12% discount so you will subtract $9.56 from %79.70 and you will get $70.14. Now we need 8.25% of %70.14 and now you have $64.36.
I hope this helps.
Answer: The value of y is 
.
Explanation:
It is given that the graph of a proportional relationship passes through (12, 16)
and (1, y).
The graph of a proportional relationship means the x and y coordinates are in a proportion k. The equation of the graph is in the form of y=kx. Where k is the proportion factor.
It is given that the graph passing through (12,16).
So the equation of the line is,
put x=1.
Therefore, the value of y is .
Answer:
5
Step-by-step explanation:
by pythagoras theorem
(hyp)^2=(leg1)^2+(leg2)^2
the hypotenuse is the side opposite to 90 degree (BC=13)
AC=leg 1 = 12
13^2=12^2 + leg 2^2
169=144+ leg 2^2
leg2 ^2=169-144
leg2^2= 25
leg2= root 25
leg2=5
One way to do this is to factor both parts of the fraction (prime factors):-
45 = 3*3*5
243 = 3*3*3*3*3
note that 3*3 is common to both factors
so we can write its as 5 / 3*3*3 = 5/27
Answer:
The combination of linear equations is
x+y = 75
y+15 = x
Step-by-step explanation:
x = representation of minutes Jack jogs
y = representation of minutes Jack bikes
Sum of 75 minutes for biking and jogging
x+y = 75
The combination of linear equations is
x+y = 75
y+15 = x
He bikes for 15 minutes higher than he jogs
y+15 = x
