Answer: $18
Step-by-step explanation:
Let x= Pretax price of the meal.
Given: Sales tax = 8%
Tip percent = 20%
As per given ,
Amount spent = ( Pretax price) + (Sales tax ) of (Pretax price) + (Tip percent)of (Pretax price)
= x+ 8% of x + 20% of x
= x +0.08+0.20x
= 1.28x
∵ Amount spent = $23.04
So,
Hence, the pretax price of the meal= $18.
4, (16,25,36,49)
5 including the number 64
Answer:
$625 for commision
Step-by-step explanation:
multiply 12,500.00 125% which is 1.25
then you get 15625, subtract 15625 - 12500 = 3125
the multiply that by 20% (.20) which is $625
Begin with cos(θ) = 5/13, θ in Quadrant IV
you should distinguish the 5-12-13 right-angled triangle
and then cosØ = adjacent/hypotenuse
x = 5, r = 13 , y = -12, since Ø is in IV
and sinØ = -12/13
also tan(ϕ) = −√15 = -√15/1 = y/x and ϕ is in II,
y = √15 , x = -1
r^2 = x^2 + y^2 = 15+1 = 16
r = 4
sinϕ = √15/4 , cosϕ = -1/4
you must know that:
cos(θ − ϕ) = cosθcosϕ + sinθsinϕ
= (5/13)(-1/4) + (-12/13)(√15/4)
= -5/52 - 12√15/52
= (-5-12√15)/52
1. 50% of the budget is spent on other:
5,000 x 0.50 = 2,500
Answer is $2,500
2. a full circle = 360 degrees
40% = 0.4
360 * 0.4 =144 degrees
3. third one shows the correct circle graph
