Percentage is a way to describe a part of a whole. The production of the footwear that will be in 2016 will be 1.65 billion.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
It is given that the production of footwear in 2006 was 1.8 billion which will be reduced by 8.4%, therefore, the number of footwear that will be produced in 2016 is 91.6%(100%-8.4%) of the production in 2006. Therefore, the production of footwear in 2016 will be
[tex]91.6\%\ of\ 2006\\\\= 0.916 \times 1.8\ billion \\\\= 1.6488\approx 1.65\ billion[/tex]

P(A and 2) = 1/12, P(D and 1) = 1/8, P(A and not 2) = 1/6
Step-by-step explanation:
P(A and 2)
There is a 1/4 chance that you hit a when you spin the spinner. There is a 2/6 chance that you hit two when you spin the spinner. 1/4*2/6 = 2/24=1/12
P(D and 1)
There is a 1/4 chance that you hit d when you spin the spinner. There is a 3/6 chance that you hit one when you spin the spinner. 1/4*3/6=3/24=1/8.
P(A and not 2)
There is a 1/4 chance that you hit a when you spin the spinner. There is a 4/6 chance that you hit anything but two in the second spinner. 1/4*4/6=4/24=1/6

The company makes a single serving cereal box that contains a volume of 1.2 ounces of cereal. They plan to make an extra large box for school cafeterias. The extra large box will be a dilation of the single serving box using a scale factor of 9/2
. How many ounces of cereal will the extra large box contain?
Answers
Answer:
109.35 ounces
Step-by-step explanation:
The scale factor is a linear scale factor.
The box is a three-dimensional solid, so the length, width, and height will be dilated by a factor of 9/2.
The volume factor is (9/2)³ = (4.5)³ = 91.125
The number of ounces is proportional to the volume.
1.2 ounces × 91.125 = 109.35 ounces

y=3x-5
y=-6x-5
????
y=8x-9
y=-8x+7
???
-x+6y=21
y=-5x+12
?????
Answers
Given:
y = 3x - 5y = -6x - 5Multiplying y = 3x - 5 by 2:
=> 2(y = 3x - 5)y = -6x - 5
=> 2y = 6x - 10y = -6x - 5
Adding both equations:
=> 3y = -15Dividing 3 both sides:
=> y = -5Substitute the value of y into any equation.
y = -6x - 5=> -5 = -6x - 5=> 0 = -6xDivide -6 both sides.
=> x = 0/-6 = 0Solution (2):Given:
y = 8x - 9y = -8x + 7Add both the equations.
y = 8x - 9y = -8x + 7
2y = -2Divide 2 both sides.
2y = -2=> 2y/2 = -2/2=> y = -1Substitute the value of y into any equation.
y = 8x - 9=> -1 = 8x - 9Add 9 both sides.
=> -1 + 9 = 8x - 9 + 9=> 8 = 8xDivide 8 both sides.
=> 8/8 = 8x/8=> x = 1Solution (3):Given:
-x + 6y = 21y = -5x + 12Reorganize the first equation.
-x + 6y = 21=> 6y = x + 21Multiply the first equation by 5.
5(6y = x + 21)y = -5x + 12
30y = 5x + 105y = -5x + 12
Add both the equations.
31y = 117Divide 31 both sides.
31y = 117=> 31y/31 = 117/31=> y = 117/31Substitute the value of y into any equation.
-x + 6y = 21=> -x + 6(117/31) = 21=> -x + 702/31 = 651/31Subtract 702/31 both sides.
=> -x = 651/31 - 702/31=> -x = -51/31=> x = 51/31Find the circumference.

Answers
Answer:
21
Step-by-step explanation:
If the angles are supplementary, that means they add up to 180 degrees.
That means if we subtract 75 from 180, we get 105.
If we divide 105 by 5, we get 21.
That means 21 * 5 + 75 = 180
or
5(21) + 75 = 180

What is the yearly salary for the RN working 40 hours
a week? How much more is an RN paid in a year than
an LPN?
Helpppppppppp
Answers
Answer:
RN = registered nurse
LPN = licensed practice nurse
RN earns $21.50 per hr
LPN earns $14 per hr
To calculate earnings for a 40 hour working week, multiply the rate per hour by 40:
RN earns: 21.50 × 40 = $860 per week
LPN earns: 14 × 40 = $560 per week
Difference: 860 - 560 = $300
Therefore, an RN is paid $300 more than an LPN for a 40 hour working week.
Number of weeks in a (non leap) year = number of days in a year ÷ 7
= 365 ÷ 7
= 52.14285714...
Rounding to the nearest whole number ⇒ 52 weeks in a year
To calculate the yearly salary, multiply the rate per week by 52:
RN earns: 860 × 52 = $44720 per year
LPN earns: 560 × 52 = $29120 per year
Difference: 44720 - 29120 = $15600
OR we can simply multiply the difference between the amount paid for a 40 hour week by 52:
⇒ 300 × 52 = $15600
Therefore, an RN is paid $15600 per year than an LPN.
