Assuming they will all pay equaliy, including the tip,
100=orignal
100+20=120
120% of 62.50
ssimlify it
120/4=30
30% of 62.50=0.3*62.5=18.75
each person pays $18.75
Answer:
<h2>: 7-⁴</h2>
Step-by-step explanation:
<h3>Exponential Form :</h3><h3>(a^m*a^n ) = (a^m+n )</h3>
<h3>7^-6 = 7^-2 * x </h3>
<h3>(only 7^-4 the term that can add to 7^-2 gives </h3><h3>= 7^-6 )</h3>
<h3>7^-6 = 7^-2 + 7^-4 </h3>
<h3> ( a^m*a^n) = ( a^m+n)</h3>
First you must know that for remarkable angles: cos (0) = 1, cos (π) = - 1, cos (π / 2) = 0, cos (3π / 2) = 0, cos (2π) = 1. Then, by simple substitution in the given formula, you can find the solutions of x. Which for the interval [0, 2π) are: x = π, x = pi divided by two and x = three pi divided by two.Attached solution.
Yes it is because 18÷6 is 3 and 6×3=18
<h3>Answer: Draw a straight line through (0,-7) and (1,-5)</h3>
Explanation:
You could use any two points you want. For me, the easiest is when x = 0. Plug this into the equation to get
y = 2x-7
y = 2(0)-7
y = -7
So we have x = 0 and y = -7 pair up to get (0,-7) as our first point. This is the y intercept.
Repeat for x = 1
y = 2x-7
y = 2(1)-7
y = -5
So (1,-5) is another point on this line. You only need two points at minimum to graph a straight line.
