a square has a perimeter of 72 units. if its length measures 3y and its width measures 2x, what is the area of the square
Answer:
324
Step-by-step explanation:
square has 4 sides.
perimeter adds all sides to make 72
72/4=18 units each side
length * width =area of square
square has all sides equal, so 3y and 2x are tricks to confuse. All sides are 18.
18*18= 324

Lesson 3-8. Write an equation for the line perpendicular to the given line through the given point.
Answer:
y = -3x + 14Step-by-step explanation:
Given line:
y = 1/3x - 2/5Perpendicular lines have negative-reciprocal slopes.
We will have a line:
y = -3x + bUse the coordinates of the given point to find the value of b:
-1 = -3(5) + b-1 = - 15 + bb = 14So the line is:
y = -3x + 14Identify the conclusion of the statement Jack will go to school if today is Monday.

5(7+n)
7(5+n)
5 + 7 + n
Answer:
The value of the algebraic expression when n is given as 6 will be 38.
An algebraic expression is when we use numbers and words in solving a particular mathematical question.
Based on the information given in the question, the expression will be:
= 1 + 7n - 5
Note that the value of n = 6
Therefore, 1 + 7n - 5 will be:
= 1 + 7n - 5
= 1 + 7(6) - 5
= 1 + 42 - 5
= 38
Step-by-step explanation:Therefore, the value of the algebraic expression when n is given as 6 is 38.

Answer:
I only know what y is, y is 4a, wait I think a is z and z is a. I’m not sure
Step-by-step explanation:
Step-by-step explanation:
value of a :
4a + a = 180°
5a = 180°
a = 36°
value of y :
y = 4a
y = 4(36)
y = 144°
value of z :
z = a
z = 36°
In London. I pint of milk costs 58p.
In Paris, 1 litre of milk costs 1.05 euros.
1 litre = 1.76 pints
£1 = 1.17 euros
In which city is the milk better value for money, London or Paris?
You must show your working.
Comparing the equivalent cost of Milk in Euro in the two countries, then we can conclude that Milk is a better value for money in Paris.
In other to make accurate comparison of the cost ; we need to using the same unit or milk and same currency value :
Cost of 1 pint of Milk in London :
1 pint = 0.58 pounds
The equivalent value of 1 pint of Milk in terms of Euro in London will be :
1 pound = 1.17 euro
0.58 pound = x
Cross multiply :
x = 1.17 × 0.58
x = 0.6786 euro
x = 0.68 euro
Hence, 1 pint of Milk cost 0.68 euro in London
Cost of 1 pint of Milk in Paris :
1 Litre = 1.76 pint
Hence,
1.76 pint = 1.05 euro
1 pint = c
1.76c = 1.05
c = 1.05 / 1.76
c = 0.597 euro
Hence, cost of 1 pint of Milk cost 0.60 euro in Paris
Therefore, since the cost of Milk in Paris cost less in Paris than in London, then Milk is a better value for money in Paris.

The number T of teams that have participated in a robot-building competition for high-school students over a recent period of time x(in years) can be modeled by T(x) = 17.155x^2 + 193.68x + 235.81, 0 ≤ x ≤ 6.
After how many years is the number of teams greater than 1000? Justify your answer.
Solving the quadratic equation, it is found that the number of teams is greater than 1000 after 3.1 years.
The number of teams after x years is given by:
[tex]T(x) = 17.155x^2 + 193.68x + 235.81[/tex]
Initially, there are T(0) = 236 teams. If will 1000 be when T(x) = 1000, thus:
[tex]17.155x^2 + 193.68x + 235.81 = 1000[/tex]
[tex]17.155x^2 + 193.68x - 764.19 = 0[/tex]
Which has coefficients [tex]a = 17.155, b = 193.68, c = -764.19[/tex], then:
[tex]\Delta = (193.68)^2 - 4(17.155)(-764.19) = 89950.66[/tex]
[tex]x_{1} = \frac{-193.68 + \sqrt{89950.66}}{2(17.155)} = 3.1[/tex]
[tex]x_{2} = \frac{-193.68 - \sqrt{89950.66}}{2(17.155)} = -14.3[/tex]
We want the positive root, so the number of teams is greater than 1000 after 3.1 years.
