The front of a house is in the shape of a hexagon with two right angles.
The other four angles are all the same size.
Calculate the size of one of these angles.
Answer: 135°
Step-by-step explanation:
The sum of the interiors angles of the hexagone is (6-2)*180°=720°
Two angles are right: 2*90°=180°
The sum of the four angles is 720°-180°=540°
Each angle is 540°/4= 135°

Explain what the vertical line test is and how it is used.
Answer:
The vertical line test is a way to figure out if a figure on a graph is a function. Imagine a vertical line goes across the graph from left to right. If the line touches two points at the same time, it's not a function.
Answer:
Sample Response: The vertical line test is a way to determine if a relation is a function. This test determines if one input has exactly one output on the graph. If any vertical line passes through more than one point on the graph, then the relation is not a function because two different outputs have the same input.

help please (picture)
Explanation:
The scale factor 3/2 is the same as 1.5
We multiply this by the perimeter 18 to get 18*1.5 = 27
The perimeter is 27 units.
This trick works because we're multiplying each length by 1.5, so ultimately the perimeter is multiplied by this same scale factor.
Which is true about the polynomial 3x - 4 + 5x2?

B
It is a trinomial with a degree of 2.
C
It is a binomial with a degree of 3.
D
It is a trinomial with a degree of 3.
Answer:
b its a trinominal with a degree of 2
The polynomial, 3x - 4 + 5x², is a trinomial with a degree of 2.
What is a polynomial?An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.
Given:
We have the polynomial,
3x - 4 + 5x²
To find the degree of a polynomial:
We take the highest powered variable, and the order of that variable is equal to the degree of the polynomial.
Here, the highest power is 2.
So, the degree is 2.
And the polynomial has three terms.
So, the polynomial is trinomial.
Therefore, it is a trinomial with a degree of 2.

The cost of 6 pounds of almonds is $23.28. What is the constant of proportionality that relates y, the cost in dollars, to x, the number of pounds?
Answer:
3.88
Step-by-step explanation:
y = 23.28/6 x
y = 3.88 x
so, the constant of proportionality is 3.88

Year 8 maths Finding the rule using a table of values
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, a) and (x₂, y₂ ) = (1, b)
m = [tex]\frac{b-a}{1-0}[/tex] = b - a
y = (b - a)x + c
(a)
with coefficient of x being b - a
(b)
The line crosses the y- axis at (0, a ) ⇒ c = a
y = (b - a)x + a
2) Jessica went to the mall. She paid $14.57 on shorts and $10.20 on pants
with two $20 bills. She went to 2 shops. How much money did Jessica get in change?
Answer:
15.23
Step-by-step explanation:
First, you add 14.57 with 10.20 which equals 24.77.
then you minus 24.77 from 40 which equals 15.23!
hope this helps you :D
Hello :D
To do this you need to do:
$20 x 2 = $40.00
$14.57 + $10.20 = $24.77
$40.00 - $24.77 = $15.23
The answer is $15.23. I hope this helps :)
what number can go into 2470,121 and 45
Answer:
Step-by-step explanation:
All of these numbers can be divided by 2, 3, 5, 7, 11, 13...
There is no whole number if you want to divide each number.
121 only goes into 1, 11, and 121. No other numbers have 11
45/2 = 22.5
45/3 = 15
45/5 = 9
2470/2 = 1235
2470/3 = 823.33333...
2470/5 = 494
121/2 = 60.5
121/3 = 40.33333...
121/5 = 24.2

One day, the ticket-selling employees forgot to count how many people came to the park. Using the inverse function (3x - 84 = y) and the number of popcorn bags sold, calculate the approximate park attendance for the following:
a. 30 bags of popcorn
b. 130 bags of popcorn
c. 520 bags of popcorn
Answer:
Step-by-step explanation:
We calculate terms in parentheses: +(3x-84-()), so:
3x-84-()
We add all the numbers together, and all the variables
3x
Back to the equation:
+(3x)
x=0/3
x=0
Answer: b
Step-by-step explanation: y=3x−84.

Answer:
2a. (360x +495)/(8x +11) = 45
2b. 2((8x+11) +45) = 16x +112
Step-by-step explanation:
a) The area is the product of length and width.
A = LW
We are given ...
W = 8x +11
A = 360x +495
The value of length can be found by solving for L:
L = A/W
L = (360x +495)/(8x +11)
The long-division solution to this is shown in the attachment.
L = 45 . . . . simplified expression for length
__
b) The perimeter of the tank is twice the sum of length and width:
P = 2(L +W)
Substituting the values for L and W, this is ..
P = 2(45 +(8x +11)) . . . . expression for length of edge seal
P = 2(8x +56)
P = 16x + 112 . . . . . . simplified expression for seal length
