Answer:4
Step-by-step explanation: Since she did it by completing the square, then you must do the same thing to get the same form so you can see what that number is.
So first subtract the constant which is -12 so we need to add twelve to get the constant on the other side. So we now have 2x^2+16x=12
The constant of the x^2 must be 1 so we need to divide by 2 on every term to get x^2+8x=12
So to make it so to get a perfect factor we need to divide the x factor by 2 so we get 4.
So the answer is 4 cause it is a perfect factor so were going to get 4 on both factors.
Answer:
4
Step-by-step explanation:
x²+2(x)(?)+?²=22
multiply by 2 because the coefficient of the higher degree in the first equation is 2
2x²+2(2(x)(?))+2(?²)-2(22)=0
2x²+4x(?)+2?²-44=0
Comparison
4x(?)=16x
?=4
2?²-44=-12
So, 2?²=-12+44
2?²=32
?²=16
?=4

A 45 degree angle is 1/8 of a circle, so keep that in mind for later. You're looking for the circumference of that 1/8 fence, so you have to use the formula, circumference/diameter=pi. Now, the problem gives you half the diameter, a.k.a the radius, so double it to get 44 ft. then, you multiply that by 3.14 (pi) to get 138.16. Now take the 1/8, from before, of the circumfrence and you get your final answer, 17.27 ft!

an employer pays three workers x,y,z a total amount of 6100 a month. x is paid 125% of the amount y is paid; which represent 80% of the amount z is paid. how much does x receive a month
Answer: 2178.57
Step-by-step explanation:
Given
The employer pays 6100 total money a month
Suppose z receives A amount
Amount paid to y is 80% of A i.e.
[tex]\Rightarrow y=0.8A[/tex]
Amount paid to x is 125% of y i.e.
[tex]\Rightarrow x=1.25y=1.25\times 0.8A=A[/tex]
The Sum of their total money must be 6100
[tex]\Rightarrow A+0.8A+A=6100\\\Rightarrow 2.8A=6100\\\Rightarrow A=2178.57[/tex]
Amount receive by x is 2178.57

Find the volume of the cylinder.
1607.7 in 3
2845.7 in 3
6430.7 in 3
401.9 in 3
Answer:
[tex]\Huge\boxed{1607.7in^3}[/tex]
Step-by-step explanation:
Hello There
The volume of a cylinder can be found using this formula
[tex]V=\pi r^2h[/tex]
where r = radius and h = height
The cylinder shown has a radius of 8 inches and a height of 8 inches
Knowing this information we plug it in into the formula
[tex]V=\pi 8^28\\8^2=64\\64*8=512\\512\pi=1607.68[/tex]
Finally we round to the nearest tenth and get that the volume of the cylinder is 1607.7 in ^3
What is the interest you will pay if you borrowed $120 at 5% interest for 6 years?
Answer:
Hope this helps!
Step-by-step explanation:
We will need the loan payment formula:
That formula is really complex and we expect you to solve it.
Your monthly payment would be $1.93 per month for 6 years making the TOTAL loan cost 1.93 * 12 * 6 = 138.96
Since the principal you borrowed is $120 the total interest =
(138.96 minus 120.00) which equals $18.96
Answer:
The answer is 36
Step-by-step explanation:
120*0.05=6
6.6=36

to answer this question you have to first split up the diagrams,I'm to lazy to do that but I'll try
area of rectangle- 2mm×4mm=8mm²
area of rectangle 2-6mm×3mm=18mm²
area of rectangle 3- 4mm×2mm=8mm²
area of triangle =1/2 b×h
=1/2×6×18
=54mm²
total area = 8mm²+18mm²+8mm²+54mm²

Find the value of x 116 degrees and 33 degrees
Answer:
x = 31 degrees
Step-by-step explanation:
This is a triangle because there are 3 angles so they all add up to 180 degrees.
116 + 33 + x + 180 Add 116 and 33
149 + x = 180 subtract both sides by 149
x = 31
