Answer:
124
Step-by-step explanation: Hope it helps
No matter how much the angle is rotated around the center, the size of the angle remains the same. Therefore, even after the rotation, the size of the angle is still 124 degrees.
When an angle is rotated around a center, the size of the angle doesn't change.
It's an important characteristic of angle rotation. So, if an angle of 124 degrees is rotated d degrees around a center, the size of the rotated angle will still remain 124 degrees. It is just in its new position after rotation. Regardless of the rotation of the angle, its size or measure remains the same as the rotation does not affect the measure of the angle.

Seems like I've done a few of these already today.
1.
a[1] = 4, d=6
Formula: a[n] = 4 + 6(n-1)
a[40]=4 + 6(39) = 238
Table: 4 10 16 22 28 34 ... a[40]=238
--------
2.
a[23]=25, d=3
a[n] = a[1] + d(n-1)
25=a[23]=a[1] + 3(22)
a[1] = 25 - 66 = -41
Table: -41 -38 -35 -32 -29 -26
Let's check a[23]= -41 + 3(22)= 25, good
Formula: a[n] = -41 + 3(n-1)

Their highest common factor (HCF) is 8.
Their lowest common multiple (LCM) is 80.
Find the two numbers, writing your answers on one line in the form,
The two numbers are ... and ...
Answer:
Step-by-step explanation:
Let the numbers be x and y
HCF is 8, so both numbers are multiples of 8 ⇒ x = 8n, y = 8m
As per property of numbers, the product of numbers is equal to product of their LCM and HCF:
Since LCM(x,y) = 80 we have:
Possible option:
Then the numbers are:
Answer:
x = 4 or x = 12
Step-by-step explanation:
Given:
y = -10x² + 160x - 430
When y = $50
50 = -10x² + 160x - 430
50 + 430 = -10x² + 160x
480 = -10x² + 160x
-10x² + 160x - 480 = 0
Divide through by -10
x² - 16x + 48 = 0
Solve the quadratic equation using factorization method
+48 = -12 × -4
-16 = -12 -4
Therefore,
-12 and -4 are both factors
x² - 16x + 48 = 0
(x - 4 )(x - 12 ) = 0
x - 4 = 0
x = 4
OR
x - 12 = 0
x = 12
Answer:
Replace y in the equation with 50: (50 = -10x2 +160x - 430) Use factoring to solve the equation. After writing the equation in standard form and dividing each side by -10, it is easy to factor as 0 = (x - 4)(x - 12).
