Answer:

For 360 km of distance , The cost of fare = Rs 112

Step-by-step explanation:

Given as :

The distance cover by rail = 900 km

The cost of 900 km = Rs 280

Let The cost of journey for 360 km = Rs x

So , ∵ For 900 km of distance , The cost of fare = Rs 280

  ∴  For 360 km of distance , The cost of fare = \frac{280}{900} × 360

Or, For 360 km of distance , The cost of fare = 0.311 × 360

∴ For 360 km of distance , The cost of fare = Rs 112     Answer

Answer:

Option B. 8.6%

Step-by-step explanation:

Simple index of two stocks: i=?

i=[(5,000*5.1+2,500*7.45)/(5,000*4.5+2,500*7.25)-1]*100%

i=[(25,500+18,625)/(22,500+18,125)-1]*100%

i=[(44,125)/(40,625)-1]*100%

i=[1.086153846-1]*100%

i=[0.086153846]*100%

i=8.6153846%

i=8.6%

What is the slope of the line that passes through the points (3, -4) and (7, 4)?
Andrews [41]
The correct option is: Option (C) 2

Explanation:

The slope formula is = m = \frac{y_2 - y_1}{x_2 - x_1}

Insert the values in the above formula:

m = \frac{4 - (-4)}{7 - 3} =  \frac{8}{4} = 2

Which is Option (C).

2. Write the equation of a circle that has a diameter of 12 units if its center is at (4,7).
ahrayia [7]

Answer:

The Answer is B

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here diameter = 12, thus radius = 12 ÷ 2 = 6 and (h, k) = (2.5, - 3.5), thus

(x - 2.5)² + (y - (- 3.5))² = 6², that is

(x - 2.5)² + (y + 3.5)² = 36 ← equation of circle

Please answer both questions and Show Work... I will mark you brainliest and give you five starts
netineya [11]

Answer:

Step-by-step explanation:

For each problem you need to make sure that the angles are the same.

So x + 22 = 90

x = 90 -22 = 68 degree

For the second problem

7x + 10 = 8x

10 = 8x -7x

x = 10 degree

Slope intercept form is y = mx + b where m is slope and b is y intercept.

The line crosses the y axis at y = 4

The slope is 4/3

So the answer is y = (4x/3) + 4
