7b. Find the value of y."
Your answer
This is a required question
Answer:
x = 36
y = 34
Step-by-step explanation:
✔️Sum of the interior angles of an n-sided polygon = (n - 2) × 180
Thus, the figure given is a hexagon with 6 sides.
Therefore, the sum of its interior angles = (6 - 2) × 180
= 4 × 180 = 720.
This means:
(5x) + (4x + 2) + (5x + 5) + (2x - 2) + (3x + 5) + (x - 10) = 720
Solve for x
5x + 4x + 2 + 5x + 5 + 2x - 2 + 3x + 5 + x - 10 = 720
Add like terms
20x = 720
Divide both sides by 20
x = 36
✔️(2y - 1) + (3x + 5) = 180 (angles on a straight line)
Plug in the value of x
2y - 1 + 3(36) + 5 = 180
2y - 1 + 108 + 5 = 180
Add like terms
2y + 112 = 180
Subtract 118 from each side
2y = 180 - 112
2y = 68
Divide both sides by 2
y = 68/2
y = 34

A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in ? In 1 hour?
Answer:
45 miles.
Step-by-step explanation:
Ok, so it goes 1.75 (1 3/4) miles in 2 minutes and 20 seconds, or 140 seconds. Divide 1.75 miles by 140 and you get 0.0125 miles per second, or 0.75 (3/4) miles per minute. Multiply 0.75 by 60 minutes and you get 45 miles.
5/8 divided by 1 1/3? In fraction form
Answer:
15/32
Step-by-step explanation:
15/32 is the fraction form of the statement 5/8 divided by 1 1/3.
To divide 5/8 by 1 1/3, we first need to convert the mixed number 1 1/3 to an improper fraction.
1 1/3 can be written as (3/3 + 1/3), which simplifies to 4/3.
Now, we can rewrite the division as the multiplication of the dividend by the reciprocal of the divisor:
(5/8) * (3/4)
Multiplying the numerators and denominators:
(5 * 3) / (8 * 4) = 15/32
Therefore, 5/8 divided by 1 1/3 in fraction form is equal to 15/32.

Is the discriminant of g positive, zero, or negative?
Answer:
The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation. A positive discriminant indicates that the quadratic has two distinct real number solutions. A discriminant of zero indicates that the quadratic has a repeated real number solution.
Step-by-step explanation:
The discriminant of the quadratic equation g is negative.
In algebra, the discriminant of a quadratic equation plays a crucial role in determining the nature of its roots. For a quadratic equation of the form ax² + bx + c = 0, the discriminant is given by Δ = b² - 4ac. Depending on whether the discriminant is positive, zero, or negative, we can determine the types of roots the equation possesses.
When the discriminant is negative, it implies that the quadratic equation has no real roots. In this case, the graph of the quadratic equation does not intersect the x-axis at all, indicating that it has complex roots. These complex roots are a pair of complex conjugates of the form (p + qi) and (p - qi), where p and q are real numbers and i is the imaginary unit (√(-1)).

Each year it loses 20% of it value at the start of this year. work out its value in 5 years time.
pls show working out
I will mark brainest and rate 5 stars
Answer:
£2,621.44
Step-by-step explanation:
Original cost of car = £8000
If it looses 20% of its value yearly
Value at the end of first year
80% * 8000
= 0.8 * 8000
= 6400
Value at the end of second year
80% * 6400
= 0.8 * 6400
= 5120
Value at the end of third year
80% * 5120
= 0.8 * 5120
= 4096
Value at the end of fourth year
80% * 4096
= 0.8 * 4096
= 3,276.8
Value at the end of fifth year
80% * 3,276.8
= 0.8 * 3,276.8
= 2,621.44
Hence the value in 5 years time will be £2,621.44

The area of the September is 336cm is all this model rectangles are exactly the same what is the perimeter of rectangle if the length of one rectangle is 12 CM
Answer:
Perimeter is 80cm
Step-by-step explanation:
A rectangle's area is calculated by multiplying the length by the width. If we are given the area of the rectangle and the length then we would simply need to solve for the width of the rectangle using the area formula we just mentioned...
A = l * w
336[tex]cm^{2}[/tex] = 12cm * w ... divide both sides by 12cm
28cm = w
Now we can see that the width of this rectangle is 28cm. To find the perimeter we need to add all four sides together, since we know that a rectangle's opposite sides are the same then we add the length and the width twice to calculate the perimeter (P)
P = 12cm + 12cm + 28cm + 28cm
P = 80cm
