10 for red and blue together and 5 for green and yellow together
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.
85/100 and in simple terms 17/20
Answer:
The focus is: 
Step-by-step explanation:
Given
Required
Determine the focus
The focus of a parabola
is:
So, we have:
Cross multiply
Rewrite as:
Rewrite as:
Express 8 as 4 * 2
By comparison with:
So, the focus is:
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>
