Answer: This coil will not be enough to complete the job.
Step-by-step explanation:
The circumference of the coil of wiring can be calculated with:
Where r is the radius and 
The radius can be calculated by dividing the diameter by 2. Then:
Convert 9 inches to yards (1 yard=36 inches):
Substitute this radius into the formula:
Since there are 21 circles of wire, you need to multiply 
by 21:
The coil has 32.97 yards of wire and Alex needs 34 yards, therefore, this coil will not be enough to complete the job.
Answer:
x+2 x+2 x+2
Step-by-step explanation:
Answer:
C.
x + 0.05x = 3.15, which has one solution
Step-by-step explanation:
Let x = the price Joshua pays for the pack of pens
He add 5% (=.05 in decimal form)
That is x* .05
The new cost is 3.15
x+.05x = 3.15
This will have one solution
Answer:
The Probability = 0.20
Step-by-step explanation:
From the question stated, the first step to take is to find probability that an employee selected at random will need either eyeglasses or major dental work
Solution
Given
Now,
The exams showed tha the number of employees needed eyeglasses = 8%
Employees that needed major dental work = 15%
Employees that needed both eyeglasses and major dental work =3%
Thus,
The P(needed eyeglasses ) = 8% = 0.08
P(major dental work) = 15% = 0.15
P(eye glasses and major dental work) = 3% = 0.03
The probability that an employee selected at random will need either eyeglasses or major dental work is given as
= P(eye glasses ) + P(major dental work) - P(eyeglasses and major dental work)
= 0.08 + 0.15 - 0.03 = 0.20
Therefore the Probability = 0.20
4x+13=5x-12
-4x. +12
25=x
3(25)-8=4y+7
75-8=4y+7
67=4y +7
-7
60=4y
y=15
lol i know this is correct bc this was a problem on my homework a couple days ago and i got it right
