Answers
Answer:
176.25in^2
Step-by-step explanation:
You can tell that the two triangles on the left, and the two triangles on the right make a rectangle if you flip one of them. Because of this, you can multiply the base and height to get the area of both.
7.5*16=120 (left side)
7.5*7.5=56.25 (right side)
Now we add them to get the full area:
120+56.25=176.25in^2

If A ( a , b ) and B ( b , a ) lie in 6x-y =1 and 2x - 5y = 5 respectively , find the equation of AB. Show your workings too!
~Thanks in advance! :D
Answers
Answer:
Solution given:
A(a,b) lie in 6x-y =1
substituting value of A in equation ,we get
6a-b=1...................(1)
B(b,a) lie in 2x - 5y = 5
substituting value of B in equation ,we get
2b-5a=5
b=5(a+1)/2............(2)
substituting value of b in equation 1 ,we get
6a-5(a+1)/2=1
12a-5a-5=2
7a=2+5
a=[tex] \frac{7}{7} [/tex]=1
substituting value of a in equation 1 ,we get
6×1-b=1
6-1=b
b=5
so points are A(1,5) and B(5,1)
we have
equation of line having two points
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1) [/tex]
[tex](y - 5) = \frac{1-5}{5-1} (x - 1) [/tex]
[tex](y - 5) = -1 (x - 1) [/tex]
y-5=1-x

Determine whether the pair of coordinate pairs will make the linear inequality true or false.(10, 6).Y ≤ -5/5x+3
Answers
Answer:
False.
Step-by-step explanation:
We have the ordered pair (10, 6) and we want to see if this ordered pair is a solution of the inequality:
y ≤ -5/5x+3
Remember that a generic ordered pair is written as (x, y)
Then for the ordered pair (10, 6) we have:
x = 10
y = 6
So we just need to replace these two values in the inequality and see if the inequality is true or false.
Replacing these values we get:
6 ≤ (-5/5*10) + 3
6 ≤ (-1/10) + 3
This is false, 6 is not less than the thing at the right, so we can conclude that (10, 6) is not a solution of the inequality.
So the coordinate pair makes the inequality false.

a.When the numerator and the denominator have no common factor other than 1; he fraction is either a proper fraction or mixed number
Answers
Answer:
The fraction is a proper fraction (and irreducible)
Step-by-step explanation:
Given
[tex]x = Numerator[/tex]
[tex]y = Denominator[/tex]
[tex]Common\ factor = 1[/tex]
Required
The type of fraction
A fraction with the given features is a proper fraction and cannot be further reduced.
Take for instance:
[tex]x = 2[/tex]
[tex]y = 7[/tex]
The only common factor between [tex]2\ and\ 7[/tex] is 1
[tex]\frac{x}{y} = \frac{2}{7}[/tex]
See that 2/7 is a proper fraction and also 2/7 cannot be reduced (simplified)
The above logic is applicable to all fraction that have the attribute stated in the question (e.g. 3/7, 3/8, 4/9, 7/10, etc.)

Answers

Sam's nature reserve is [tex]14\times 10^6\ m^2[/tex]
Also, [tex]1\ \text{hectare}=10,000\ m^2[/tex]
Devin reserve in square meter [tex]14\ \text{hectares}=14\times 10^4\ m^2[/tex]
Clearly, [tex]14\times 10^6> 14\times 10^4[/tex]
