How to give a fraction of an hour

Answer:

see explanation

Step-by-step explanation:

∠ A and ∠ FCE are corresponding angles and are congruent , then

∠ A = 150°

∠ FCE and ∠ C are vertically opposite angles and are congruent , then

∠ C = 150°

∠ FCE and ∠ ECB are adjacent angles on a straight line and sum to 180°

∠ ECB = 180° - ∠FCE = 180° - 150° = 30°

∠ E = 180° - (30 + 45)° ← sum of angles in a triangle

∠ E = 180° - 75° = 105°

∠ CBE and ∠ D are same- side interior angles and sum to 180° , then

∠ D = 180° - 45° = 135°

Answer:

Step-by-step explanation:

We can use the point-slope formula to write an equation for this line. The point-slope formula states :

where m  is the slope and (x1   y1)  is a point the line passes through .

We can substitute the slope and values from the point to give:

(y-1) = 8 (x-7)

We can also transform this equation to the slope-intercept form by solving for  

y

. The slope-intercept form of a linear equation is: y=mx+b

where the m is the slope and b s the y-intercept value.

y-1= (8 times x) - ( 8 times 7)

y-1=   8x - 56

y-1 + 1= 8x- 56 + 1

y-0=  8x- 55

y= 8x - 55

Expand 359 as a sum of the largest powers of 2 that you can:

359 = 256 + 103

359 = 256 + 64 + 39

359 = 256 + 64 + 32 + 7

359 = 256 + 64 + 32 + 4 + 3

359 = 256 + 64 + 32 + 4 + 2 + 1

359 = 2⁸ + 2⁶ + 2⁵ + 2² + 2¹ + 2⁰

359 = 1 0110 0111₂

Answer:

$212.5

Step-by-step explanation:

x= 100*170/80

x= 17000/80

x= 212.5

Step-by-step explanation:

the slope of a line is the ratio y/x.

that means when going from one point to the other, how many units is y changing, when x changes a certain number of units.

so, going from one point to the other here, x changes by 30 units (from -12 to +18). and y changes 15 units (from -9 to 6).

therefore, the slope is

15/30 = 1/2

Step-by-step explanation:

51 3/5 = 258/5

258/5 / 4 = 12.9 (meters the submarine dives each min)

now we have to find out what 12.9 is as a fraction!

12.9= 12 9/10 because .9 is equal to 9/10, and 12. equals 12!

Answer:

The roots of the equations are 2 and 6.

The equation of the form ax² + bx +c is known as a quadratic equation.

Given that, the quadratic equation is x² - (4 + p)x + 12= 0.

Let the roots of the quadratic equation be a and b.

If the coefficient of x² is 1 in a quadratic equation, then the coefficient of x is equal to the sum of the roots and the constant term is equal to the product of the roots.

Therefore,

a + b = -(4 + p)    (1)

ab = 12                (2)

Given that, one root is three times the other, so, let a = 3b and substitute it into equation (2)

3b(b) = 12

3b² = 12

b² = 4

b = 2

Therefore, the value of a is:

a= 3(2)

a = 6

Hence, the roots of the equations are 2 and 6.

Step-by-step explanation:

Answer:

steps below

Step-by-step explanation:

Set    log x = a     and     log y = b

x = 10ᵃ     and       y = 10ᵇ

if a>b      10ᵃ > 10ᵇ

so  x > y

x = 57²⁰¹⁸              y = 51²⁰²⁰

log x = log 57²⁰¹⁸ = 2018 * log 57 = 3543.36 :  (a)

log y = log 51²⁰²⁰ = 2020 * log 51 = 3449.29 : (b)

3543.36 > 3449.29       log x > log y    

x > y:        57²⁰¹⁸ > 51²⁰²⁰

Answer:

  perpendicular: undefined

  parallel: zero

Step-by-step explanation:

The line y = -6 is a horizontal line. Between any two points on the line, the difference in y-values is zero, and the difference in x-values is non-zero. The slope of this horizontal line is the ratio of these differences:

  slope = 0/(non-zero) = 0

Any parallel line will have the same slope. The slope of a parallel line is 0.

__

A line perpendicular to a horizontal line is a vertical line. It will have the equation x = constant. Between any two points on the line, the difference in y-values is non-zero, and the difference in x-values is zero. The slope of this vertical line is the ratio of these differences:

  slope = (non-zero)/0 = undefined

The slope of the perpendicular line is undefined.
