Answer:
60+4.5pi
Step-by-step explanation:
First find the area of the rectangle alone which is l*w
so 6*10 is 60,
then, you find the area of the semicircle which is 1/2pir^2
so 1/2(pi)(3^2) = 4.5pi
the radius is 3 because its 6/2
then you add it together which is 60+4.5pi
Answer:
Step-by-step explanation:
A of rect. + A of semicircle = Area of the figure
lb + [tex]\frac{\pi r^2}{2}[/tex]
Length of rectangle = 6
Breadth of rectangle = 10
Diameter of semicircle = 6
Radius of semicircle = 3
∴ (6x10) + [tex](\frac{22}{7}[/tex]x[tex]3^2[/tex] x[tex]\frac{1}{2}[/tex])
= 60 + [tex]\frac{99}{7}[/tex]
= 74.14 cm sq
Round off to nearest tenths place = 70 cm sq

Answer: (6x+10)
Step-by-step explanation:
To find the side of the square, we have to first factorise it:
[tex]36x^2[/tex] + 120x + 100
= 36[tex]x^2[/tex] + 60x + 60x + 100
= 12x(3x + 5) + 20(3x + 5)
= (12x+20)(3x+5)
= 4(3x+5)(3x+5)
= 2(3x+5)2(3x+5)
= (6x+10)(6x+10)
∴ Hence, side = (6x+10) units

In the first week of July, a record 1,060 people went to the local swimming pool. In the second week, 105 fewer people went to the pool. In the third week, 135 more people went to the pool than in the second week. In the fourth week, 136 fewer people went to the pool than in the third week.
What is the percent change in the number of people who went to the pool between the first and last weeks?
Answers
Answer:
The percent change in the number of people who went to the pool
between the first and last week is 10% less
Step-by-step explanation:
The given is:
. In the first week of July, a record 1,060 people went to the local swimming
pool
In the second week, 105 fewer people went to the pool
⚫ In the third week, 135 more people went to the pool than in the second week
. In the fourth week, 136 fewer people
went to the pool than in the third week
We need to find the percent change in the number of people who
went to the pool between the first and last weeks
::There were 1060 people in the 1st week
There were 105 fewer people in the 2nd week .. The number of people in the 2nd week =
1060 - 105 = 955
.. There were 955 people in the 2nd week
:: There were 135 more people in the 3rd
week than the 2nd week
There were 955 people in the 2nd week
.. The number of people in the 3rd week = 955 + 135 = 1090
There were 1090 people in the 3rd week
:: There were 136 fewer people in the 4th week than in the 3rd week
There were 1090 people in the 3rd week
.. The number of people in the 4th week =
1090-136 = 954 .. There were 954 people in the 4th week
Let us find the change from 1st week to last week
: There were 1060 people in the 1 st week
There were 954 people in the last week
.. The change = 1060-954 = 106
:: Percent change =
Change
Original * 100%
.. Percent change = * 100%
106
1060 Percent change = 10%
The percent change in the number of people who went to the pool
Learn more:
between the first and last week is 10% less
percent change = (new value - old value) / old value x 100
First we need to find the number of people who went to the pool in the last week, which is the number of people who went in the first week minus 105, plus 135, minus 136.
So:
Last week = 1060 - 105 + 135 - 136 = 954
Then we can calculate the percent change:
percent change = (954 - 1060) / 1060 x 100 = -10%
So the percent change in the number of people who went to the pool between the first and last weeks is -10%. This means that the number of people who went to the pool in the last week is 10% less than the number of people who went in the first week.

A rectangle has a width that is twice the length. If the area of the rectangle is represented by the expression 18x² + 48x + 32, what expression represents the length of the rectangle? Explain.
Answers
Answer:
Step-by-step explanation:
Length of rectangle = l (let length of rectangle be 'l')
Width of rectangle = 2l
Area of rectangle = lb --> l(2l)
∴ Here, the area is given = [tex]18x^2 + 48x + 32[/tex]
So,
Area of rectangle = lb
[tex]18x^2 + 48x + 32[/tex] = l x 2l
[tex]18x^2 + 48x + 32[/tex] = [tex]2l^2[/tex]
[tex]\frac{18x^2 + 48x + 32}{2}[/tex] = [tex]l^2[/tex]
[tex]\sqrt{\frac{18x^2 + 48x + 32}{2}}[/tex] = [tex]l[/tex]
∴ Length is [tex]\sqrt{\frac{18x^2 + 48x + 32}{2}}[/tex]

V=πr^2h
You have the diameter which is 2 times to radius. In order to get the radius you half the diameter which is 9.
9 to the second power is 81. Then you multiply it by the height which is 11. 81 x 11 is 891. So 891 x pi would be about 2799.16.
2r=d 2 r = d.
So plug in 18m in as d.
2r=18
/2 /2
r= 9
The volume of a cylinder is v= πr^2h
Use Pi symbol in calculator unless specified to use 3.14
The height is 11m
V=πr^2h
V= π(9)^2(11)
V= π(81)(11)
V= π(891)
V= 2,799.159054348506
So, to the nearest whole number: v= 2,800 m
