What’s the value of k?

Answers

Answer: k = 5°

Step-by-step explanation:

A triangle adds up to 180°. Therefore, the equation is 115 + (4k + 5) + (6k + 10) = 180.Remove the parenthesis and combine the like terms. 115 + 5 + 10 = 130 and 4k + 6k = 10k. The equation simplifies to 130 + 10k = 180.Subtract 130 on both sides. 10k = 50Divide by 10 on both sides. k = 5

Answer:

The value of k is 10°

Step-by-step explanation:

Assuming that straight line is 180°. First, you have to find the angle of ZYX by subtracting 115° from 180° :

∠ZYX = 180° - 115° = 65°

Given that total angles in a triangle is 180°. So you have to add up all the angles in the triangle in terms of k :

∠XZY + ∠ZYX + ∠ZXY = 180°

4k + 5 + 65 + 6k + 10 = 180

10k + 80 = 180

10k = 180 - 80

10k = 100

k = 100 ÷ 10

k = 10

10x - 10 = 180°

10x = 190° divide both sides by 10

x = 19

To Find:

The root of the equation.

Solution:

By adding 125 to both the sides, we get

[tex] \huge {\sf { {x}^{3} = 125}} [/tex]

Take cube to the RHS (Right Hand Side), we get

[tex] \huge {\sf { x = 5}}[/tex]

Answer: x = 5

The solution to the expression is x = 5.

We have,

Expression:

x³ - 125 = 0

This can be written as,

x³ = 125

Now,

Cube of 5:

5³ = 5 x 5 x 5 = 125

Now,

x³ = 5³

Cube cancels out on both sides.

x = 5

Thus,

The solution to the expression is x = 5.

What is the slope of the line that passes through the points (10,5) and (9,5)? Write
your answer in simplest form.

Answers

Answer:

slope of line is 0.

Step-by-step explanation:

Slope of a line passing through (x1,y1) and (x2,y2) is given by

m = (y2-y1)/(x2-x1)

Given points are  (10,5) and (9,5)

thus

slope = (5-5)/(9-10) = 0/-1 = 0

Thus, slope of line is 0.

When slope of line is zero it means that the line the which passes through given point is parallel to x-axis.

The slope of the line that passes through the points (10,5) and (9,5) is 0.

Using slope formula,

m = y₂ - y₁ / x₂ - x₁

Therefore,

(10,5) (9,5)

m = 5 - 5 / 9 - 10

m = 0 / -1

m = 0

Therefore, the slope of the line that passes through the points (10,5) and (9,5) is 0.

The coordinates of points A and B are A(4, -2) and B(12, 10). What are the coordinates of the point that is 1/4 of the way from A to B?

Answers

Answer:

Step-by-step explanation:

(4 + 12)/4 = 16/4 = 4

(-2 + 10)/2= 8/4 = 2

(4, 2) is 1/4 of the way from A to B

The coordinates of the point that is 1/4 of the way from A to B is (28/5, 2/5) if the coordinates of points A and B are A(4, -2) and B(12, 10).

What is an ordered double?

It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).

[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]

It is given that:

The coordinates of points A and B are A(4, -2) and B(12, 10)

The coordinates of the point that is 1/4 of the way from A to B

The above statement means that the line segment AB is divided in the ratio of 1:4 internally.

Using the section formula:

Let C be the new coordinate point:

C(x) = [1(12) + 4(4)]/(1+4)

C(x) = 28/5

C(y) = [1(10) + 4(-2)]/(1+4)

C(y) = 2/5

Thus, the coordinate of the point that is 1/4 of the way from A to B is (28/5, 2/5) if the coordinates of points A and B are A(4, -2) and B(12, 10).

To solve this expression we will use the logarithmic properties.

[tex]\text{log}(\frac{1000a^3}{b})=\text{log}1000a^3-\text{log}(b)[/tex] [Since, [tex]\text{log}\frac{p}{q}=\text{log}p-\text{log}q[/tex]]

An equation is a mathematical statement formed when two expressions are equated using an equal sign.

The equations are useful in the determination of unknown parameters.

The equations are of various types, such as Trigonometric equations, and quadratic equations.

Roselyn's family lives 150 km away.

Her average speed is 60km/h

The car tank has 20 L of fuel at the beginning of the the drive.

Fuel efficiency is 6km/ L.

The cost of the fuel is $0.60/L.

The total drive is 150km.

The 6km of distance requires 1 L of fuel

Step-by-step explanation:

First, you have to convert the units, since kilograms and grams aren't the same unit. 1000 grams=1 kilogram. Keep that in mind, and lets move on.

So, that means 3 kilograms=3,000 grams. Let's rewrite our ratio.

500g:3,000g

So now they're the same units, but it isn't simplified. This last parts easy. To simplify a ratio, find the number you can divided both number with. In this situation, that number is 500. 500 divided by 500= 1, and 3,000 divided by 500= 6.

A rectangular lawn is 40 feet by 50 feet. How wide a uniform strip has been mowed around
the edge if 3/10 of the lawn has not yet been mowed?

Answers

Answer:

The width of the strip is 28 ft

Step-by-step explanation:

First lest us calculate the area of the rectangle

given that

length= 50ft

width= 40 ft

Area = length *width

Area=  50*40

Areaa= 2000 ft^2

given that 3/10 of the lawn is yet to be mowed

(3/10)*2000

0.3*2000= 600ft^2

Therefore the area that has been mowed is 2000-600= 1400 ft^2

1400 ft^2

since the direction of the mower is along the lenght of the lawn

area= lenght*width

1400= 50*width

width= 1400/50

width= 28 ft

Suppose f(x)=4x-2 and g(x)=-2x+1. Find the value of f(5)/g(-3)

Answers

Answer:

17/7 (2 3/7 or 2. 428571...)

Step-by-step explanation:

f(x) = 4x-2

Find f(5)

f(5) = 4(5)-3f(5) = 20-3f(5) = 17

g(x) = -2x+1

Find g(-3)

g(-3) = -2(-3)+1g(-3) = 6+1g(-3) = 7

Find f(5)/g(-3)

f(5)/g(-3)17/7 (2 3/7 or 2. 428571...)

The value of f(5)/g(-3) will be 18/7.

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The value of the function are,

⇒ f (x) = 4x - 2 and

⇒ g(x) = -2x + 1

Now,

Since, The value of the function are,

⇒ f (x) = 4x - 2 and

⇒ g(x) = -2x + 1

Hence, We get;

⇒ f (5) = 4 × 5 - 2

          = 20 - 2

         = 18

And, g (- 3) = - 2 × - 3 + 1

⇒ g (-3) = 6 + 1

            = 7

Thus, The value of f(5)/g(-3) = 18/7

If Jamie is riding at 14 mph and cori is riding at 0.04km per minute, how far will each of yjem bike in two hours? 1 mile = 1.61 km use the equation D=V/T

Answers

Answer:

Jamie will have covered a distance of 45.08 km while Cori will be 4.8 km away

Step-by-step explanation:

Here, we want to know how far will each of both riders be in 2 hours time.

Jamie is riding 14 mph

This means the number of miles covered in two hours will be 14 mph * 2 = 28 miles

For comparison purposes, let’s convert this to kilometer.

Since 1 mile = 1.61 km, then 28 miles will be 28 * 1.61 km = 45.08 km

For Cori, he is riding at 0.04 km per minute

1 hour = 60 minutes

so 2 hours = 2 * 60 = 120 minutes

Since the speed is 0.04 km in a minute

Then the distance in 120 minutes will be 0.04 * 120 = 4.8 km
