Answers
Answer:
111
Step-by-step explanation:
divide 222 by 2 and you get your answer
Answer:
55.5
Step-by-step explanation:
since we don't know the length or width of any side, one length side will only be 1/4 of 222. And perimeter is all the sides added up. This rectangle will actually be a square.
222/4=55.5

if the length of diagonal of a square is 4-√2 cm, find it's length, perimeter and area.
Answers
Step-by-step explanation:
1) the length of the side is:
[tex]\frac{4-\sqrt{2} }{\sqrt{2}}=2\sqrt{2}-1.[/tex]
2) the required perimeter is:
[tex]P=4(2\sqrt{2} -1)=8\sqrt{2} -4.[/tex]
3) the required area is:
[tex]A=(2\sqrt{2} -1)^2=9-4\sqrt{2}.[/tex]
Answer:
Side length = (2√2 - 1) units
Perimeter = (8√2 - 4) units
Area = (9 - 4√2) units²
Step-by-step explanation:
Properties of a square:
It is a quadrilateralThe opposite sides are parallelAll four sides are equal in lengthAll interior angles measure 90°The diagonal of a square creates two right triangles, with the diagonal being the hypotenuse, and the sides of the square being the 2 legs.
Let x = side length of the square
Using Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
⇒ x² + x² = (4 - √2)²
⇒ 2x² = 18 - 8√2
⇒ x² = 9 - 4√2
⇒ x = ±(2√2 - 1)
⇒ x = 2√2 - 1 only (as distance is positive)
Perimeter of a square = 4x
= 4(2√2 - 1)
= 8√2 - 4
Area of a square = x²
= (2√2 - 1)²
= 9 - 4√2
This is the same triangle you used for Question 2. Triangle ABC has angle measures as shown below. Using the information in the diagram, and the value of x that you calculated i Question 2, find the measure of Angle C. In your answer, give the measure of Angle C and explain how you calculated it.

simplify 15a+21b-6a-4
Answers
Answer:
9a+21b-4
Step-by-step explanation:
first of all combine the like terms
15a + 21b - 6a - 4
= 9a + 21b - 4 Ans.
The simplified expression of 15a+21b-6a-4 is 9a+21b-4
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is 15a+21b-6a-4
Fifteen times of a plus twenty one times of b minus six times of a minus four.
a and b are the variables and plus, minus are the operators
Add the like terms in the expression
15a-6a+21b-4
Fifteen times of a and minus six times of a are the like terms.
So add these like terms.
When 15 and -6 are added we get 9
So the expression becomes as Nine times of a plus twenty one times of b minus four.
9a+21b-4
Hence, the simplified expression of 15a+21b-6a-4 is 9a+21b-4

A lawyer charges a $75 consultation fee and then $120 per hour thereafter.
a). Identify the dependent and independent variable.
b). Make a table of values for the cost of $C of an appointment with the lawyer for time t hours where t= 0,1,2,3,4.
c). What is the relationship between C and t linear?
d). If you graphed this relationship, is it sensible to join the points graphed with a straight line? Give reason with your answer.
e). For every increase of 1 hour for t, what is the change in C?
f). For an appointment with the lawyer, what is the fixed cost and variable cost?

Answer:
(a) The dependant veriable is the $120 per hour and the independant veriable is the $75 consultaion fee.
(b) The table of vaules for this would look like this, [tex]\frac{C}{T} \frac{75}{0} \frac{195}{1} \frac{315}{2} \frac{435}{3} \frac{555}{4}[/tex], where C = cost and T = time.
(c) The relationship between C and T is linear, beacause with the more hours you take the cost increases.
(d) Yes, it is sensible because the points would be in line due to the steady increase of the hourly rate.
(e) For every hour spent the cost increases 120 dollars.
(f) The fixed cost is 75 dollars for consultation and the veriable cost is 120 per hour.
