Answer:
l =10 units, 9.7 units, 5.5 units
Step-by-step explanation:
Area = length x breadth
Area of a square = l^2
100= l^2
√100 =√l^2
l=10 units
95=l^2
√95 = √l^2
l= 9.7 units
30=l^2
√30=√l^2
l= 5.5 units
The green object below,is best defined as a ___ named____.
The green object below, is best defined as a Ray named AC.
In geometry, a ray is a part of a line that consists of a single initial point called the endpoint and extends infinitely in one direction. It can be thought of as a half-line, with one end point and the other end extending infinitely.
Rays are named using two points, with the endpoint being mentioned first.
Here, in the figure the green line has one point A and the next C and it is further extending.
Thus, the Green line is a Ray name as ray AC.

Answer:
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
Step-by-step explanation:
the perimeter of the rectangular yard needs to be 20 yards
Perimeter of a rectangle = 2 x ( length + width)
20 = 2 x ( length + width)
( length + width) = 20 /2
( length + width) = 10
The sum of the length and width should equal 10
Possible dimensions that would equal 10 are :
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
Lamar has a list of 600 pages to read to finish his book for his upcoming book report. He sets a goal to read half of the pages left in his book each day.
Answer:
a.) Total pages Lamar have to read the first day to meet his goal = 300
Total pages left to read after 3 days = 75
b.) Total pages he need to read on day 8 = 4.6875
Step-by-step explanation:
The exact question is as follows :
Given - Lamar has a list of 600 pages to read to finish his book for his upcoming book report. He sets a goal to read half of the pages left in his book each day.
To find -
a) How many pages will Lamar have to read the first day to meet his goal?
How many will he have left to read after 3 days?
b) How many pages will he need to read on day 8?
Solution -
Given that,
Total number of pages = 600
Now,
In Day 1 ,
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (600)[/tex] = 300
i.e.
In Day 1 , he Finished 300 pages.
So,
At the end of Day 1, total pages left = 600 - 300 = 300
so,
Total pages Lamar have to read the first day to meet his goal = 300
Now,
For day 2 ,
Total pages = 300
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (300)[/tex] = 150
i.e.
In Day 2 , he Finished 150 pages.
So,
At the end of Day 2, total pages left = 300 - 150 = 150
Now,
For day 3 ,
Total pages = 150
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (150)[/tex] = 75
i.e.
In Day 3 , he Finished 75 pages.
So,
At the end of Day 3, total pages left = 150 - 75 = 75
So,
Total pages left to read after 3 days = 75
Now,
For day 4 ,
Total pages = 75
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (75)[/tex] = 37.5
i.e.
In Day 4 , he Finished 37.5 pages.
So,
At the end of Day 4, total pages left = 75 - 37.5 = 37.5
Now,
For day 5 ,
Total pages = 37.5
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (37.5)[/tex] = 18.75
i.e.
In Day 5 , he Finished 18.75 pages.
So,
At the end of Day 5, total pages left = 37.5 - 18.75 = 18.75
Now,
For day 6 ,
Total pages = 18.75
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (18.75)[/tex] = 9.375
i.e.
In Day 6 , he Finished 9.375 pages.
So,
At the end of Day 6, total pages left = 18.75 - 9.375 = 9.375
Now,
For day 7 ,
Total pages = 9.375
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (9.375)[/tex] = 4.6875
i.e.
In Day 7 , he Finished 4.6875 pages.
So,
At the end of Day 7, total pages left = 9.375 - 4.6875 = 4.6875
So,
At the starting of Day 8,
Total pages = 4.6875
So,
Total pages he need to read on day 8 = 4.6875

1. A box without a top is to be made from a rectangular piece of cardboard, with dimensions 3 in. b)
in., by cutting out square corners with side length x and folding up the sides.
Answer:
a) The volume of the box is represented by [tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex].
b) A side length of 0.653 inches leads to the maximum volume of the box: 6.299 inches.
Step-by-step explanation:
a) The volume of the box ([tex]V[/tex]), in cubic inches, is modelled by the equation for the cuboid:
[tex]V = (3-2\cdot x) \cdot (7-2\cdot x) \cdot x[/tex] (1)
Where [tex]x[/tex] is the side length of the cutted square corners, in inches.
[tex]V = (21 - 20\cdot x + 4\cdot x^{2})\cdot x[/tex]
[tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex]
The volume of the box is represented by [tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex].
b) The method consist in graphing the polynomial and looking for a relative maximum. We graph the equation found in a) by means of a graphic tool. We present the outcome in the image attached below. According to this, a side length of 0.653 inches leads to the maximum volume of the box: 6.299 inches.

The Vertical Angles Theorem states that vertical angles, angles that are opposite each other and formed by two intersecting straight lines, are congruent. This means that 48° should equal (7x+13)°, because they're vertical angles. The equation should appear as 48=7x+13. Subtract 13 on both sides to get. 35=7x. Divide 7 on both sides to result with x=5.

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Fiona deposited $900 in the bank over 2 years.
She earned $60 in simple interest at the end of the 2 years.
We have to find the annual interest rate
I=PRT
60=900×2×T
60=1800T
Divide both sides by 1800
T=3.33%
Hence, the annual interest rate is 3.33%

Step-by-step explanation:
look at the number line. I always had trouble with this so I get where your coming from first, look at where the line is touching don't pay attention to the box yet because it's confusing the entire point of this line is to show you that there MAY have been 1 or two people who where at 0 for this data and 1 or two people who were at 15
the point here is that the bulk of the data was 11-14, but because there were less people down lower, the mean of the data is at 13, and the data is bigger (skewed) to the left.

Sara hina and Arslan have a total of RS 390in their wallet . Sara has Rs. 7more than Hina .Arslan has 3 times what sara has . How much do they have in their wallets?
Answer:Sara hina and Arslan Have RS79.4,RS 72.4 and RS238.2 respectively.
Step-by-step explanation:
Step 1
Let the amount that hina has be x
the amount that sara has be represented as 7+x
and the amount that Arslan have be represented as 3(7+x)
such that the total amount in their wallet which is 390 can be expressed as
x+7+x + 3(7+x)=390
Step 2
Solving
x+7+x +21+3x=390
5x+28=390
5x==390-28
x=362/5=72.4
Hina has RS 72.4
Sara =7+x==72.4+77= RS 79.4
Arslan =3(7+x)=3 x 79.4=RS 238.2
