Step-by-step explanation:

(i) y = 3x

m = 3

Slope of the line perpendicular to line (y = 3x) = -1/m = -1/3

Answer:

The volume is 196 cubic yards

Step-by-step explanation:

Given

[tex]Base\ Area = 7yd * 2yd[/tex]

[tex]Height = 14yd[/tex]

Required

The volume

The volume is given as:

[tex]Volume = Base\ Area * Height[/tex]

Where:

[tex]Base\ Area = 7yd * 2yd[/tex]

[tex]Height = 14yd[/tex]

So, the equation becomes

[tex]Volume = 7yd * 2yd * 14yd[/tex]

[tex]Volume = 196yd^3[/tex]

Answer:

Shaded region is 18.3 units²

Step-by-step explanation:

First find the area of the white triangle.  The base and height of this triangle are both 8.  Thus, the area of the triangle is (1/2)(base)(height), or 32 units.

Next, find the area of the whole circle.  It is πr², which in this case comes

out to π(8 units)² = 64π units².  Realize that (1/4) of this, or 16π units², is the area of the quarter circle that contains the triangle.

To find the shaded area, take the area of the quarter circle (16 π units²) and subtract the area of the triangle (32 units²).

16π units² - 32 units² = 18.3 units²

Shaded region is 18.3 units²

i)It ended at  21:13

ii) 440*10/100

44 mins longer

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

110% = 440 minutes (Tuesday journey)

100% = 100/110 x 440

100% = 400 minutes (Monday journey)

Tuesday's journey took 40 minutes longer than Monday's journey.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

On Tuesday the train journey took 7 hours and 20 minutes and began at

13:53.

The time train journey ended.

= 13:53 + 7 hours + 20 minutes

= 13 hours + 53 minutes + 7 hours + 20 minutes

= 20 hours + 73 minutes

= 20 hours + 60 minutes + 13 minutes

= 20 hours + 1 hour + 13 minutes

= 21 hours + 13 minutes

This means,

= 21:13

The train ended the journey at 21:13

Tuesday's time of 7 hours and 20 minutes was 10% more than Monday's journey time.

This means,

Converting into minutes.

7 hours 20 minutes

= 60 x 7 + 20 minutes

= 420 minutes + 20 minutes

= 440 minutes

Monday's journey time.

110% = 440 minutes:

100% = 100/110 x 440

100% = 400 minutes

Thus,

Tuesday's journey took 40 minutes longer than Monday's journey.

Step-by-step explanation:

Answer:

D. $892.50

Step-by-step explanation:

First we find out the interest:

850 * 2.5% = 21.25

Since this is 2 years we multiply the interest by 2.

21.25 * 2 = 42.50

Now we add the interest with the amount borrowed.

850 + 42.50 = $892.50

So, the answer is $892.50 in total.

Answer:

Yes, the sides form a right triangle.

Step-by-step explanation:

Pythagorean Theorem:

a² + b² = c²

↓

20² + 21² = 29²

║a² = 20² = 400

║b² = 21² = 441

║c² = 29² = 841

↓

400 + 441 = 841

║This equation is true.

↓

Yes, the sides form a right triangle.

Answer:

x = -9 and x = 5

Step-by-step explanation:

[tex] {(x + 2)}^{2} + 1 = 50[/tex]

[tex] = {x}^{2} + 4x + 4 + 1 = 50[/tex]

[tex] = {x}^{2} + 4x + 5 = 50[/tex]

[tex] = {x}^{2} + 4x + 5 - 50 = 0[/tex]

[tex] = {x}^{2} + 9x - 5x - 45 = 0[/tex]

[tex] = x \times (x + 9) - 5(x + 9) = 0[/tex]

[tex] = (x + 9) \times (x - 5) = 0[/tex]

[tex] = x + 9 = 0[/tex]

[tex] x - 5 = 0[/tex]

[tex] = x = - 9[/tex]

[tex]x = 5[/tex]
