Answer:Center: (0,1)
Radius: √66
Step-by-step explanation:
Set each set of parentheses to 0 and solve for the x’s
X-1= 0
Add 1 to both sides
X =1
X-7 = 0
Add 7 to both sides
X = 7
The zeros are 1,7
To plot them make dots at (1,0) and (7,0)
If you are finding the perimeter the answer would be:
$15.50
If you do 9*$1.75=$15.75
If you do 10*$1.75=17.50
When you find perimeter it’s length+length+ width+ width
This gives you $15.50
If you are finding the area the answer would be:
$157.50
To find area you do 10*9=90
Then, you do 90*$1.75=$157.50
Answer:
Step-by-step explanation:
Step one:
Given data for Heather's company
Fixed cost = $5000
Additional cost = $250
in a week there are 168 hours
hence they will produce a total of 168/5= 33.6
=34 systems
the expression for the total cost can be modeled as
c=mn+f
where c=total cost
m= the Additional cost
n= number of systems produced per hour
h= the number of systems produced per hour
f= fixed cost
Step two:
c=mn+f
given that n=34, we can find the total cost as
c=250(34)+5000
c=8500+5000
c=13500
the total cost for each week is $13,500
Answer:
Naomi had the correct measurement the ring weighed 0.625 carats
Step-by-step explanation:
* The diamond ring weighed 5/8 carats
- To know who is right lets change the fraction 5/8 to a decimal number
∵ 5/8 means 5 ÷ 8
- 5 is smaller than 8 so we will multiply it by 10 and
insert decimal point in the quotient (answer of division)
∴ It will be 50 ÷ 8 = 6 and remainder 2/8 ⇒ 1/4
∴ The quotient = 0.6 and remainder 1/4
- 1 is smaller than 4 so we will multiply it by 10
∴ It will be 10 ÷ 4 = 2 and remainder 2/4 ⇒ 1/2
∴ The quotient = 0.62 and remainder 1/2
- 1 is smaller than 2 so we will multiply it by 10
∴ It will be 10 ÷ 2 = 5 without remainder
∴ The quotient = 0.625
* Naomi had the correct measurement the ring weighed 0.625 carats
