Reena bought a mobile phone for 16,240 that included a GST of 12%. Find the price of the mobile phone before the GST was added.
Person who answers will be marked brainliest
Answer: 14500
Step-by-step explanation:
Let the price of the mobile phone before the GST was added be represented by x.
Therefore,
x + (12% × x) = 16240
x + 0.12x = 16240
1.12x = 16240
x = 16240/1.12
x = 14500
The price of the mobile phone before the GST was added was 14500

Answer: 1.567 × 10⁹
Step-by-step explanation:
1.6 × 10⁹ = 1.6 × 1000000000 = 1,600,000,000
3.3 × 10⁷ = 3.3 × 10000000 = 33,000,000
1,600,000,000 - 33,000,000 = 1,567,000,000

If the sum of measures of angle a and b is 280 degrees, what is the measure of angle C?
A. 80 degrees
B. 160 degrees
C. 140 degrees
D. 40 degrees
Answer:
40 degrees
Step-by-step explanation:
because angle b and angle a are vertical angles they are congruent and if they add up to 280 you just have to divide that by 2 to get the value of one of the angles
280/2=140
because angle c and angle b are supplementary they are going to add up to equal 180
180-140=40 so c=40
Answer:
40

What is the image of (- 4, 3) after a dilation by a scale factor of 2 centered at the origin?
Answer: (-8,6)
Step-by-step explanation:
Question: What is the image of (-4,3)(−4,3) after a dilation by a scale factor of 22 centered at the origin?
Dilation: multiply each coordinate
(x,y)\rightarrow (2x,2y)
(x,y)→(2x,2y)
Dilations multiply by scale factor
(\color{red}{-4},\color{blue}{3}) \rightarrow (2\cdot \color{red}{-4},2\cdot \color{blue}{3})=\mathbf{(-8,6)}
(−4,3)→(2⋅−4,2⋅3)=(−8,6)
This was on my delta math so i hope this helps
The image of the point (- 4, 3) after dilation will be (-8,6).
What is dilation?Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.
The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making.
Given point is (-4, 3). The dilation of the point will be calculated as below:-
Dilation:- multiply each coordinate.
(x,y)→(2x,2y)
Dilations multiply by a scale factor
(−4,3)→(2⋅−4,2⋅3)=(−8,6)
Therefore, the image of the point (- 4, 3) after dilation will be (-8,6).

The diagram shows the position
of three towns represented by
letters A, B and C.
B is 7 km from A on a bearing of 037°
C is 8 km from B on a bearing of 140°
Find the bearing of C from A.
Give your answer correct to 1 decimal place.
Answer:
56.29
Step-by-step explanation:
56.29^° is the answer
The bearing of town C from town A at the given position of the three towns is determined as 93.3⁰.
Distance of C from A
The distance of town C from town A is calculated by applying Cosine rule. The distance of town C from town A is represented by small letter "b" as shown in the image.
b² = a² + c² - 2ac[cos B]
b² = (8)² + (7)² - 2(8 x 7 x cos77)
b² = 87.81
b = √87.81
b = 9.37 km
Angle AThe value of angle A is determined by applying Sine rule as shown below;
sin A/a = sin B/b
sin A = (a x sin B)/b
sin A = (8 x sin 77)/9.37
sin A = 0.832
A = sin ⁻¹ (0.832)
A = 56.3⁰
Bearing of town C from town AThe bearing of town C from town A is determined from the sum of 37⁰ and angle A.
θ = A + 37⁰
θ = 56.3⁰ + 37⁰
θ = 93.3⁰
Thus, the bearing of town C from town A at the given position of the three towns is determined as 93.3⁰.
