Answer:

[tex]A = 52[/tex], [tex]B = 38[/tex]

Step-by-step explanation:

The sum of two complementary angles is always [tex]90[/tex]°

[tex]A + B = 90[/tex]

[tex]A = B + 14[/tex]

substitute [tex]A[/tex] for [tex]B = 14[/tex]

[tex](B + 14)+ B = 90[/tex]

[tex]2B + 14 = 90[/tex]

[tex]2B = 76[/tex]

[tex]B = 38[/tex]

input this into the original equation

[tex]A + 38 = 90[/tex]

[tex]A = 52[/tex]

Answer:

(0, 3)

Step-by-step explanation:

The equation already shows the y-intercept (written as +3). The slope is -4x and the y-intercept is (0, 3).

Answer:

y=3

Step-by-step explanation:

Because we know x equals 0 we put that into the equation so then you have y=4(0)+3 you multiply 4 time 0 and get 0 so all you have left is 3.

Sample answer on Plato

Answer: Its 6:15

Step-by-step explanation:

Its simple math. 7:00 subtract 45minutes, knowing that 60minutes is an hour and that its the 7 hour from the 6 hour. Gets you 6:15.

Yep.

The 45 minutes before 7 o'clock will be 6.15 AM/PM.

the indefinite continued progress of existence and events in the past, present, and future regarded as a whole.

In other words, time is something which measure by motion and it is given by einstein that time depends upon motion.

For example time = distance/velocity so it means time also depends on velocity.

In the given question, we know that in

1 hour  = 60 minutes

45 minutes before of 7 o'clock = 60 - 45 = 15 minutes after 6 o'clock hence 6.15 minutes will be correct answer.

Step-by-step explanation:

x - 4 = 0

=> x = 4

f(x)= 5x – 22x - 2x² – 25x +4

By remainder theorem,

f(4)= 5(4) – 22(4) - 2(4)² – 25(4) + 4

    = 20 - 88 - 32 - 100 + 4 ≠ 0

Since the remainder is not 0, x - 4 is not a factor.

Hope it helps :)

Hello there!

Your question asks to find what was the size of the population in 2017

Answer: 6,721

In order to solve this problem, we're going to need to use the given information in the question in order to find the population in 2017.

Key information:

In 2010, population was 6500

In 2014, population increased by 10% from 2010

In 2017, population decreased by 6% from 2014.

With the information above, we can solve the problem.

We're going to start with 6500 as our starting population.

We know that the population increased by 10% in 2014, so we would multiply 6500 by 1.10.

Answer:

8) interior angle = 160

9) x = 20

Step-by-step explanation:

8)

18-gon has 18 sides

The formula for sum of interior angles for an 18-gon is:

(18x180)-360 = 2880 degrees

2880 degrees / 18 angles = 160 degrees

9)  

exterior angles = 360 degrees

360 = (3x-2)+(x+8)+(4x+9)+(2x-1)+(3x)+(4x+6)

360 = 3x-2+x+8+4x+9+2x-1+3x+4x+6

360 = 17x+20

17x = 340

x = 20 degrees

Answer: The number of child tickets is 85 and the number of adult tickets is 95.

Step-by-step explanation:

Let C = Number of child tickets

A = Number of adult tickets.

As per given, we have

C+A=180          (i)

7C+13A=1830           (ii)

Multiply 7 to both sides of equation (ii), we get

7C+7A=1260     (iii)

Eliminate (iii) from (ii) , we get

[tex]6A=570\\\\\Rightarrow\ A=95[/tex]

Put value of y in (i), we get

C= 85

Hence, the number of child tickets is 85 and the number of adult tickets is 95.
