what is 0.9 repeating as a rational number? ​

Answer:

[tex]4.5375*10^1[/tex]

Step-by-step explanation:

we know that

[tex]45\frac{3}{8}=45+\frac{3}{8}=45+0.375=45.375[/tex]

Convert decimal number in scientific notation

A number expressed in  scientific notation   has the form

[tex]a*10^{n}[/tex]

where

[tex]1\leq a < 10[/tex]

n is a integer

Expressing 45.375 in this form means writing the number as a value between 1 and 10

so

For a=4.5375,n=1

[tex]45.375=4.5375*10^1[/tex]

Final answer:

The mixed number 45 3/8 can be expressed in scientific notation as 4.5375 *[tex]10^2[/tex] by first converting it to an improper fraction, then to a decimal, and finally moving the decimal point two places to the left.

Explanation:

To write the mixed number 45 3/8 in scientific notation, let's first convert it into an improper fraction and then into a decimal. The mixed number 45 3/8 is equivalent to (45 * 8 + 3) / 8, which simplifies to 363/8 or 45.375 as a decimal.

Now, to express this in scientific notation, we move the decimal point two places to the left so that the number falls between 1 and 10. As a result, we get 4.5375. Since we moved the decimal two places to the right, we multiplied by 10 to the power of 2([tex]10^2[/tex])

Finally, 45 3/8 in scientific notation is 4.5375 *( [tex]10^2[/tex] ).

The height of the tree = 15m.

let us say the height of the tree=h

in this problem,

the height of the sam can be treated as perpendicular of a right-angle triangle.

while his shadow can be treated as the base of the same triangle.

now, we need to calculate the angle of elevation α

it is the angle between the line of sight and the horizon.

hence,

the tangent of the angle of elevation α= height/length of the shadow

tanα= 5/4

tan α = height of the tree/length of the shadow of the tree

5/4 = h/12

h=15m

therefore, the height of the tree = 15m

Margaret needs 2 1/2 cups of sugar and chocolate chips to make the fudge.

To make the fudge, Margaret needs 1 1/4 cups of sugar and 1 1/4 cups of chocolate chips.

To find the total number of cups needed, add the amounts of sugar and chocolate chips: 1 1/4 + 1 1/4 = 2 1/2 cups.

Therefore, Margaret needs 2 1/2 cups of sugar and chocolate chips to make the fudge.

The equation of the line with a slope of 2/3 and y-intercept of 4 is y = 2/3x + 4.

The equation of a line in slope-intercept form (which is the most common form we deal with in algebra) is y = mx + b, where m is the slope and b is the y-intercept.

In this case, you're given that the slope (m) is 2/3 and the y-intercept (b) is 4. Substituting these values into the equation gives you the equation of the line: y = 2/3x + 4.

This is the equation that represents the given line

Final answer:

The equation of the line with a slope of 2/3 and a y-intercept of 4 is y = 2/3x + 4.

Explanation:

To find the equation of a line with a slope of ⅓ and a y-intercept of 4, we can use the slope-intercept form of a line, which is y = mx + b where m is the slope and b is the y-intercept.

The given slope is ⅓, so m = ⅓. Given that the y-intercept is 4, b = 4.

Plugging these values into the slope-intercept equation, we get y = ⅓x + 4, which is the equation of the desired line.

The equation of a line is a mathematical expression that describes the relationship between the independent variable (x) and the dependent variable (y) for points on that line in a Cartesian coordinate system. It allows you to represent a straight line graphically on a two-dimensional plane.

Answer:

40

explanation:

240 ÷ 6 = 40

The value of expression 240 divided by 6 would be equal to 40

When 'a' is divided by 'b', then the result we get from the division is part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We need to find the expression of 240 divided by 6

A negative divided by a negative is positive

240 ÷ 6 = 40

Therefore, The value of 240 divided by 6 is; 40

Answer:

C✔(*/ω＼*)

Step-by-step explanation:

None of the given equations are perpendicular to the equation '5y = 2x +4'. This is because perpendicular lines have reciprocal, negative slopes and none of the given lines meet this criteria.

To find the equations that are "perpendicular" to the given equation 5y = 2x +4, we first need to find out the slope of the given equation. The slope of the equation is obtained by rearranging it into the y=mx+b form where m stands for the slope. Thus, y=(2/5)x+4/5, which gives us a slope (m) of 2/5.

Perpendicular lines have slopes that are negative reciprocals of each other. So, for a line to be perpendicular to the given line, it should have a slope of -5/2.

Given the equations 7 y = 6x + 8, 4y = 8, and y + 7 = 3x, let's find out their slopes. The slope for the first equation is 6/7, for the second equation is undefined as it's a horizontal line, and for the third equation is 3. Hence, none of these lines are perpendicular to the given line. Similarly, none of the lines Y2 = -173.5+ 4.83x − 2(16.4) and line Y3 = -173.5+ 4.83x + 2(16.4) don't have a slope of -5/2 and hence, are not perpendicular to the given line.

Answer:

w=6

Step-by-step explanation:

3w+5=23

3w=23-5

3w=18

w=6

The solution to the equation 3w + 5 = 23 is w = 6.

The given equation is 3w + 5 = 23.

We need to solve for w.

Subtract 5 from both sides of the equation to isolate the term with 3w:

3w + 5 - 5 = 23 - 5

3w = 18

Divide both sides of the equation by 3 to solve for w:

(3w) / 3 = 18 / 3

This simplifies to:

w = 6

Therefore, the solution to the equation 3w + 5 = 23 is w = 6.

Answer:

The x-intercept is at -8 and the y-intercept is at -5.

Step-by-step explanation:

When you simplify 5x + 8y = 40 into y = mx + b form, you get y = -5/8x - 5.

Answer: x-intercept is (-8,0) and y-intercept is (0,-5)

Step-by-step explanation:

5x+8y=-40

To find the x-intercept, you plug in 0 in for y.

5x+8(0)=-40

5x=-40

Then solve for x

5x/5=-40/5

x=-8

The x-intercept is (-8,0)

To find the y-intercept, you plug in 0 in for x

5(0)+8y=-40

8y=-40

Solve for y

8y/8=-40/8

y=-5

y-intercept is (0,-5)
