Answer:

2ln5 + ln4 + ln5

Step-by-step explanation:

Think about how we can write 500 in terms of 4 and 5.

[tex]500 = 5^2*(4*5)[/tex]

So ln(500) can be written as ln(5^2*4*5)

Using log rules [tex]log_b(x*y)=log_b(x)+log_b(y)\\logb(x^a)=a*log(x)[/tex]

we can rewrite ln(500) to 2ln5 + ln4 + ln5

Using the properties of equality, the value for m in the equation is: m = pV.

For any given equation, to solve for a variable in the equation, we have to isolate the variable to one side of the equation in order to determine its value. To do this, several properties of equality need to be applied to isolate the variable to one side of the given equation.

Given the equation, p = m/V, we need to isolate the variable m to one side of the equation in order to solve for m.

p = m/V

Multiply both sides of the equation by V

p × V = m/V × V [multiplication property of equality]

Simplify the equation:

pV = m

m = pV

The Sumerians were different from other people of their time as they wee more advanced.

The Sumerians were a southern Mesopotamian people whose civilisation flourished between approximately 4100 and 1750 BCE. Sumer was an ancient civilization that flourished in the Fertile Crescent region of Mesopotamia, between the Tigris and Euphrates rivers. Sumerians are regarded as the creators of civilisation as we know it today, according to their advancements in language, governance, building, and other fields.

They were able to take technologies produced elsewhere and use them on a far larger scale. This allowed them to mass-produce commodities such as textiles and pottery, which they could subsequently trade with others.

Answer:

x = –1/3 and y = 11/3

or can be written as (–1/3, 11/3)

Solve the system of equations:

1x + 2y = 7

y = –2x + 3

Substitute y = –2x + 3 for y in the first equation:

1x + 2y = 7

1x + 2(–2x + 3) = 7

Substract 6 from both sides:

–3x + 6 = 7

–3x + 6 – 6 = 7 – 6

–3x = 1

Divide:

–3x/–3 = 1/–3

x = –1/3

Substitute –1/3 for x in the second equation:

y = –2x + 3

y = –2(–1/3) + 3

y = 11/3

Solution:

x = –1/3 and y = 11/3

In the above question,

It is given that a line that passes through a point = (7 ,8)

The slope of the line = m = -3

The inclination of a line with respect to the horizontal is measured numerically is called as Slope

We know the slope intercept form of the line is

( y - y1) = m (x - x1)

where (x1 , y1 ) = ( 7 , 8)

and  m = -3

Putting values in the slope intercept form of line, we get

( y - 8) = -3 ( x - 7)

y - 8 = -3x + 21

3x + y -8 - 21 = 0

3x + y - 29 = 0

y = -3x + 29

The average speed of this particle over the interval 2 ≤ t ≤ 10 is 25 , the correct option is (b)25  .

In the question ,

it is given that

the position of the particle that travels along the x-axis at time t is given by the function

x(t)=2t²+t

the average speed of the particle can be calculated by using the formula

average speed = (change is distance)/(change in time)

particle position at t=2

x(2) = 2(2)²+2 = 2*4+2 = 10

particle position at t=10

x(10) = 2(10)²+(10)

= 2*100+10

= 200+10

= 210

So, change in distance = 210-10= 200

change in time = 10-2 = 8

Putting the values in the average speed formula we get

average speed = 200/8

= 100/4

=25

Therefore , the average speed of this particle over the interval 2 ≤ t ≤ 10 is 25 , the correct option is (b)25  .

Answer:

1.95 hours or 1 hour and 57 minutes.

Step-by-step explanation:

You can read the problem as 13% of the battery. "Of" is a keyword that means to multiply.

The battery lasts 15 hours, so multiply by 13%. You need to change 13% to a decimal first by dividing it by 100, or moving the decimal left two places.

13% = 0.13

Now solve.

0.13 × 15 = 1.95

If you need to convert the 0.95 to minutes, multiply it by 60 since there are 60 minutes in an hour.

0.95 x 60 = 57 minutes.

259 pieces of candy can be distributed in 80 bags to give 3 candy per bag and there will be 19 candies remaining

The concept for distributing the required candies is achieved by the mathematical operation called division.

Division is an inverse of multiplication. With division we can share and determine number of candy per bag

The question is solved by

= 259 ÷ 80

= 259 / 80

= 3 19/80

This means that there will be 3 candies per bag and after sharing among the nags there will be 19 candies remaining.

Putting this in decimal gives

= 3.2375 ≅ 3.24

In a situation where we are to count the candies if they are 3.25 pieces per bag the we multiply as follows

= 3.25 * 80

= 260

Answer:

2a + b = 180
 a + b = 118

a = 64, b = 56

Step-by-step explanation:

If you look at the triangle on the top right of the diagonal, there are 3 angles a, a and b. Since the 3 angles of a triangle add up to 180°

      a + a + b = 180

=>   2a + b = 180.......(1)

We are given that the largest angle is 118°

The largest angle of the parallelogram is a + b. Remember that opposite angles of a parallelogram are equal and the sum of the angles add up to 360

Therefore a + b = 118 ....(2)

Given equations (1) and (2), subtract (1) from (2):

Eq (1) - Eq(2) :

2a + b - (a + b) = 180 - 118

a = 62

Substitute for a in equation (2) to get

a + b = 118

62 + b = 118

b = 118 - 62 = 56

So the two angles are a = 64° and b = 56°

Answer:

a = 62, b = 56

Step-by-step explanation:

given the largest angle is 118° , then

a + b = 118 ( subtract b from both sides )

a = 118 - b → (1)

the sum of the interior angles of a quadrilateral = 360°

the angle adjacent to a is b ( alternate angles ) , then

a + b + a + a + b + a = 360

4a + 2b = 360 → (2)

substitute a = 118 - b into (2)

4(118 - b) + 2b = 360

472 - 4b + 2b = 360

472 - 2b = 360 ( subtract 472 from both sides )

- 2b = - 112 ( divide both sides by - 2 )

b = 56

substitute b = 56 into (1)

a = 118 - 56 = 62

a = 62 and b = 56

A set of parallel lines and a set of perpendicular lines are: BF║CG, AD⊥BF.

Parallel lines are straight lines that are of equal distance at every point away from each other, and therefore, do not intersect each other at any point. The sign "║" is used to indicate that two lines are parallel lines.

Lines that are said to be perpendicular lines are lines that intersect each other at right angle or 90 degrees. That is, at the point of their intersection, a right angle is formed which is 90 degrees. The sign "⊥" is used to indicate that two lines are perpendicular lines.

In the image given, lines BF and CG do not intersect at any point and they are of equal distance away from each other at every point, therefore, CG and BF are perpendicular lines.

Also, we can see that a right angle is formed at the point of intersection of lines AD and BF, therefore AD and BF are perpendicular lines.

The perimeter of the regular polygon is 108 units.

A regular polygon is a polygon that has all its sides equal to each other.

Therefore,

5(x + 2) = 7x + 4

5x + 10 = 7x + 4

5x - 7x = 4 - 10

-3x  = -6

x = -6 / -3

x = 2

The perimeter of a regular polygon is the sum of the whole sides of the polygon.

Therefore,

each side of the regular polygon = 7(2) + 4

each side of the regular polygon = 14 + 4
