Mikel gave a $1.32 tip for an order that cost $8.80
notsponge [240]

Answer:

1. Proportional

2. Not proportional

3. Not proportional

Step-by-step explanation:

Let's see what percentage of the $8.80 order is the $1.32 tip.

To find what percent a p[art is of a whole, divide the part by the whole and multiply by 100%.

$1.32/$8.80 * 100% = 15%

Mike's tip was $15% of the total.

1. $2.22 tip on $14.80 order

15% of $14.80 = 0.15 * $14.80 = $2.22

Tip is proportional

2. $1.86 tip on $10.50 order

15% of $10.50 = 0.15 * $10.50 = $1.58

Tip is nor proportional

3. Same as option 2 above.

Find the focus of the parabola whose equation is y=1/8 x^2
Mama L [17]

Answer:

The focus is: (0,2)

Step-by-step explanation:

Given

y = \frac{1}{8}x^2

Required

Determine the focus

The focus of a parabola

(x- h)^2 = 4p(y - k)

is:

(h,k+p)

So, we have:

y = \frac{1}{8}x^2

Cross multiply

8y = x^2

Rewrite as:

x^2 = 8y

Rewrite as:

(x - 0)^2 = 8(y - 0)

Express 8 as 4 * 2

(x - 0)^2 = 4 * 2(y - 0)

By comparison with: (x- h)^2 = 4p(y - k)

h = 0    p =2     k = 0

So, the focus (h,k+p) is:

(h,k+p) = (0,0+2)

(h,k+p) = (0,2)

A pack of cinnamon-scented pencils sells for $5.00. What is the sales tax rate if the total cost of the pencils is $5.25?
IgorLugansk [536]
The sales tax rate is 5%

Given:
Sales price = 5.00
Total amount paid = 5.25

Sales tax value = Total amount paid - sales price
                          = $5.25 - $5.00 
Sales tax value = $0.25
Sales tax rate = Sales tax / Sales price
<span>                        = 0.25/5 </span>
<span>Sales tax rate  = 0.05 or 5%</span>
