Step-by-step explanation:
given the perimeter is
64ft
the length l= 3w
we know that the perimeter of a rectangle is given as
P=2l+2W
but L=3w
64=2(3w)+2w
64=6w+2w
64=8w
divide both sides by 8 we have
w=64/8
w=8ft
also
let the lenght of the rectangle be l
side of hexagon=l-4
perimeter of hexagon
P=5(l-4)
P=5l-20
width of rectangle w=l-2
perimeter of rectangle= 2l+2w
but w=l-2
5l-20= 2l+2(l-2)
5l-20=2l+2l-4
5l-20=4l-4
5l-4l=-4+20
l=16ft
perimeter of hexagon
P=5(l-4)
put l=16
perimeter of hexagon
P=5(16-4)
p=5(12)
P=60ft
Answer: 2(3(8))+(2+8)=64 or c
Step-by-step explanation:
You have to replace w with 8 meaning 8 is now the width, therefore, c is the correct answer.

Factor each completely.
10a² - 9a + 2
Answer:
a= [tex]\frac{2}{5}[/tex] or [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Equate the equation to zero
[tex]10a^{2}[/tex]-9a+2=0
[tex]10a^{2}[/tex]-5a-4a+2=0
5a(2a-1)-2(2a-1)=0
Write out the factors
(5a-2)(2a-1)=0
Then equate each factor to zero
5a-2=0 OR 2a-1=0
5a=2 OR 2a=1
a= [tex]\frac{2}{5}[/tex] OR a= [tex]\frac{1}{2}[/tex]
a=[tex]\frac{2}{5}[/tex] or [tex]\frac{1}{2}[/tex]

Is the line through points p (3,-5) and Q(1,4)parallel to the line through points R( -1,1) and S (3,-3)
Answer:
No
Step-by-step explanation:
To find out if the lines that go through the pairs of points are parallel, we must find the slope of each line. If the slopes are equivalent, then they are parallel. If not, then they are not parallel.
We can use the slope formula to find the slope between two points. The slope formula is:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope between the points (x₁, y₁) and (x₂, y₂).
Lets first find the slope between points P and Q.
[tex]m=\frac{-5-4}{3-1}=\frac{-9}{2}=-4.5[/tex]
So the slope between P and Q is -4.5.
Now lets find the slope between the points R and S.
[tex]m=\frac{-3-1}{3-(-1)}=\frac{-4}{4}=-1[/tex]
So the slope between R and S is -1.
Since -4.5 does not equal -1, the lines are not parallel.

Answer:
It lies between 5 and 6
Step-by-step explanation:
Two consecutive numbers are numbers that come after each other:
x , x + 1 are consecutive numbers.
3 \sqrt{3} = 3√3 = 5.19615242271
Therefore, from the above calculation, we can see that square root of 3 is a number that is between consecutive numbers 5 and 6

Answer:
[tex]{\huge{\pink{\underline{\underline{Solution:}}}}}[/tex]
As we know,sum of angles on a straight line is 180 degree..
(5z-4)+90+39=180
=>5z-4+90+39=180
=>5z-4+129=180
=>5z+125=180
=>5z=180-125
=>z=55÷5
Hence,the value of z=11 degree

Find the value of the variable.
The required value of variable m is 15.
Gvien that,
A line segment AC is given, On which B is the midpoint,
AB = 3m + 5
and BC = 4m - 10
AB = BC
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
AC is the line segment where B is the midpoint on the line AC. So,
AC = AB + BC
AB = BC
3m + 5 = 4m - 10
m = 15
Thus, the required value of variable m is 15.

What is the y-intercept of the quadratic function
f(x) = (x - 6)(x - 2)?
Answer:
y = 12 → (0|12)
Step-by-step explanation:
f(x) = (x - 6)(x - 2)
y = (x - 6)(x - 2)
y = x² - 6x - 2x + 12
y = x² - 8x + 12
y = 0² - 8*0 +12
y = 12

Hope this Helps! :)
Have any questions? Ask below in the comments and I will try my best to answer.
-SGO
Answers:
a) 80% nonfiction
b) 1200 fiction, 4800 nonfiction
=========================================
Explanation:
part (a)
We only have two choices: fiction or nonfiction
If 20% are fiction, then 100% - 20% = 80% are nonfiction.
The two percentages 20% and 80% add to 100% to represent all the books.
---------------------
part (b)
20% = 20/100 = 0.20
20% of 6000 = 0.20*6000 = 1200
we have 1200 fiction books
6000-1200 = 4800
and we have 4800 nonfiction books
Note how
80% of 6000 = 0.80*6000 = 4800
which helps confirm part (a)
The barrel of a fountain pen, cylindrical in shape, is 7 cm long and 5 mm in diameter. A full
barrel of ink in the pen is used up on writing 3300 words on an average. How many words can
be written in a bottle of ink containing one fifth of a litre?
Answer:
480,000 words
Step-by-step explanation:
For barrel of pen:
h = 7 cm, d = 5 mm
r = 5/2 = 2.5 mm = 0.25 cm
[tex]Volume \: of \: barrel = \pi {r}^{2} h \\ \\ = \frac{22}{7} \times {(0.25)}^{2} \times 7 \\ \\ = 22 \times 0.0625 \\ \\ = 1.375 \: {cm}^{3} \\ \\ one \: fifth \: of \: a \: litre \\ = \frac{1}{5} \times 1000 \: ml \\ \\ = 200 \: ml \\ \\ = 200 \: {cm}^{3} \\ \\ no \: of \: words = \frac{3300 \times 200}{1.375} \\ \\ = \frac{660000}{1.375} \\ \\ = 480,000 \\ [/tex]
