Answer:

- 1 2/3 < 1/4

Step-by-step explanation:

hope this helps!!

The relationship between the numbers -1 2/3 and -1/4 in an inequality is -1 2/3 > -1/4. This is because -1 2/3 is closer to zero than -1/4, meaning in the negative number line, -1 2/3 is greater than -1/4.

To create an inequality that describes the relationship between the given numbers, -1 2/3 and -1/4, first convert them into the same form. Both of these numbers are negative, but -1 2/3 is greater because it is closer to zero.

So the inequality which represents this relationship is -1 2/3 > -1/4.

Let's convert them into improper fractions to make it easier to understand.

So, -1 2/3 becomes -5/3 and -1/4 remains the same as -1/4. Hence our inequality becomes -5/3 > -1/4, which confirms that -1 2/3 is greater than -1/4.

Answer:

-7

Step-by-step explanation:

Lets assume the number Peggy is thinking of be "x".

Now as given, when twice the number is added to three times one more than the number. We can write it as

∴ [tex]2x+3(x+1)[/tex]--- Equation 1

Again, it is given that Peggy gets the same result as when she multiplies four times one less than the number.

∴ [tex]4(x-1)[/tex]-- equation 2

Next, we can equate both the equation 1 and 2 as it is given that result is same.

[tex]2x+3(x+1)= 4(x-1)[/tex]

Let´s distribute 3 into [tex](x+1)[/tex] and 4 into [tex](x-1)[/tex]

⇒ [tex]2x+3x+3=4x-4[/tex]

⇒ [tex]5x+3=4x-4[/tex]

Subtract both side by 4x and 3

∴ [tex]x=-7[/tex]

If x₂ - x₁ = 0

Since division by zero is undefined then the slope of the line is undefined

This applies to a vertical line parallel to the y- axis

Answer:

Step-by-step explanation:

Let us suppose r be the total number of meals eaten in a restaurant

Let us suppose c be the total number of meals eaten in a car

Let us suppose h be the total number of meals eaten in a home

Substituting Equation [B] into [A],

[tex]r + c + h = 171.....[A][/tex]

[tex]r + r + 11 = 171[/tex]

[tex]2r + 11 = 171[/tex]

Answer:

About 14.29 minutes

Step-by-step explanation:

Each page has 125 words

There are 4 pages

SO, total number of words:

125 * 4 = 500 words

The rate of typing is 35 wpm (words per minute)

So, to find time it will take to type 500 words is found by dividing the number of words (500) by the rate (35), so we have:

500/35 = 14.2857 minutes

So, it will take about 14.29 minutes to type up the whole documentary

Solve for h

That means ----> isolate the variable h

subtract  2πr² both sides

[tex](SA-2\pi r^{2})=2\pi rh[/tex]

Divide by 2πr both sides

[tex]\frac{SA-2\pi r^{2}}{2\pi r}=h[/tex]

[tex]h=\frac{SA}{2\pi r}-r[/tex]

Step-by-step explanation:

4x + 10 = 32

4x = 32 - 10

4x = 22

x = 11/2

if we add 4 to both sides of the equation :

4x + 10 + 4 = 32 + 4 ➡ 4x + 14 = 36

4x = 36 - 14 ➡ 4x = 22 and x = 11/2

as you can see the value for x didn't change because when we add/subtract or multiple/divide same number from both sides of an equation the result won't change.

Answer:

The length of the rectangular field is (3 a - 3) meters

Step-by-step explanation:

Given as :

The Perimeter of rectangular field = p = ( 10 a - 6 ) meters

The width of the rectangular field = w = 2 a meters

Let The length of the rectangular field = L meters

Now From The perimeter formula

Perimeter of rectangular field = 2 × Length + 2 × width

Or, p =  2 × L +  2 × w

Or,  ( 10 a - 6 ) meters =  2 × L meters + 2 × 2 a meters

Or, 10 a - 6 =  2 × L + 4 a

Or, 10 a - 4 a - 6 = 2 L

Or, 6 a - 6 = 2 L

∴  L = [tex]\dfrac{6 a - 6}{2}[/tex]

i,e L = 3 a - 3

So, The length of the rectangular field = L = (3 a - 3) meters

Hence,The length of the rectangular field is (3 a - 3) meters  Answer

m = total measures of music she must memorise - (number of measures she memorises per day x d)

m = 90 - 6(d)

m = 90 - 6d

Step-by-step explanation:

Point (-12 , 8) is on the line that passes through (0, 6) and is parallel to the given line ⇒ 1st

Step-by-step explanation:

Parallel lines have:

The formula of the slope of a line which passes through points [tex](x_{1},y_{1})[/tex] and [tex](x_{1},y_{1})[/tex] is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

∵ The given line passes through points (-12 , -2) and (0 , -4)

∴ [tex]x_{1}[/tex] = -12 , [tex]x_{2}[/tex] = 0

∴ [tex]y_{1}[/tex] = -2 , [tex]y_{2}[/tex] = -4

- Use the formula of the slope above to find the slope of the given line

∵ [tex]m=\frac{-4-(-2)}{0-(-12)}=\frac{-4+2}{12}=\frac{-2}{12}=\frac{-1}{6}[/tex]

∴ The slope of the given line is [tex]\frac{-1}{6}[/tex]

∵ The two lines are parallel

∴ Their slopes are equal

∴ The slope of the parallel line = [tex]\frac{-1}{6}[/tex]

∵ The parallel line passes through point (0 , 6)

- The form of the linear equation is y = mx + b, where m is the slope

  and b is the y-intercept (y when x = 0)

∵ m = [tex]\frac{-1}{6}[/tex] and b = 6

∴ The equation of the parallel line is y = [tex]\frac{-1}{6}[/tex] x + 6

Let us check which point is on the line by substitute the x in the equation by the x-coordinate of each point to find y, if y is equal the y-coordinate of the point, then the point is on the line

Point (-12 , 8)

∵ x = -12 and y = 8

∵ y = [tex]\frac{-1}{6}[/tex] (-12) + 6

∴ y = 2 + 6 = 8

- The value of y is equal the y-coordinate of the point

∴ Point (-12 , 8) is on the line

Point (-12 , 8) is on the line that passes through (0, 6) and is parallel to the given line

The point on the line that passes through (0, 6) and is parallel to the given line is (2, 8).

To find a point on a line parallel to the given line, we can use the slope of the given line, which is equal to the slope of the parallel line.

The slope of the given line can be calculated using the coordinates (-12, -2) and (0, -4):

Slope (m) = (change in y) / (change in x) = (-4 - (-2)) / (0 - (-12)) = (-2) / (12) = -1/6.

Now that we know the slope of the parallel line is -1/6, we can use the point-slope form of a linear equation to find the equation of the parallel line:

y - y1 = m(x - x1),

where (x1, y1) is the point (0, 6) and m is the slope (-1/6). Plugging in these values:

y - 6 = (-1/6)(x - 0),

y - 6 = (-1/6)x,

y = (-1/6)x + 6.

Now, we can choose any x-value to find the corresponding y-value. If we plug in x = 2 into the equation, we get:

y = (-1/6)(2) + 6 = -1/3 + 6 = 8.

So, the point (2, 8) is on the line that passes through (0, 6) and is parallel to the given line.

Answer: number 2

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Answer: z = 3

Step-by-step explanation: To solve this equation for z, we can first combine our like terms on the left side of the equation. Since 12 and 7 both have z after their coefficient, we can subtract 12z - 7z to get 5z.

Now we have 5z - 2 = 13.

To solve from here, we add 2 to the left side of the equation in order to isolate 5z. If we add 2 to the left side, we must also add 2 to the right side. On the left side, the -2 and +2 cancel out. On the right, 13 + 2 simplifies to 15.

Now we have 5z = 15.

Solving from here, we divide both sides of the equation by 5 to get z alone. On the left side, the 5's cancel out and we are simply left with z. On the right side, 15 divided by 5 simplifies to 3 so we have z = 3.

The correct answer is:

Jessica can wax approximately 34,533,185 square meters per hour at her constant rate of waxing the floor.

To find out how many square meters Jessica can wax per hour, we first need to convert the square miles to square meters, then divide by the time taken.

1. Convert square miles to square meters:

  Since 1 mile = 1609.34 meters, to convert square miles to square meters, we square this conversion factor:

[tex]\[ 1 \text{ mile}^2 = (1609.34)^2 \text{ meters}^2 \] \[ 1 \text{ mile}^2 = 2,589,988.36 \text{ meters}^2 \][/tex]

  So, 20 square miles would be:

[tex]\[ 20 \text{ miles}^2 \times 2,589,988.36 \text{ meters}^2/\text{mile}^2 = 51,799,767.2 \text{ meters}^2 \][/tex]

2. Calculate the rate per hour:

  Jessica waxes 20 square miles in [tex]\( \frac{3}{5} \)[/tex] of an hour.

  So, her rate per hour is:

 [tex]\[ \frac{20 \times 2,589,988.36}{\frac{3}{5}} \text{ meters}^2/\text{hour} \][/tex]

  To simplify the calculation, we'll first find the reciprocal of [tex]\( \frac{3}{5} \): \[ \frac{1}{\frac{3}{5}} = \frac{5}{3} \][/tex]

  Now, we multiply the reciprocal by 20 square miles:

 [tex]\[ 20 \times 2,589,988.36 \times \frac{5}{3} \text{ meters}^2/\text{hour} \] \[ \text{meters}^2/\text{hour} = 34,533,184.8 \][/tex]

So, Jessica can wax approximately [tex]\( 34,533,184.8 \)[/tex] square meters per hour at her constant rate.

Answer:

(-4,2)

Step-by-step explanation:

Answer:

(-4,2)

Step-by-step explanation:

Answer:

15.7 years

Step-by-step explanation:

Use the formula for compound interest. A = P(1 + i)ⁿ

A is the total amount of money. A = 7200

P is the principal, starting money. P = 3000

i is the interest per compounding period in decimal form. Since interest is compounded annually, i = 0.0575

n is the number of compounding periods. n = ?

Substitute the information into the formula and isolate n.

A = P(1 + i)ⁿ

7200 = 3000(1 + 0.0575)ⁿ    Solve inside the brackets

7200 = 3000(1.0575)ⁿ

7200/3000 = 1.0575ⁿ       Divide both sides by 3000

2.4 = 1.0575ⁿ

n = (㏒ ans) / (㏒ base)

n = (㏒ (2.4)) / (㏒ (1.0575))

n = 15.659.....     Exact answer

n ≈ 15.7       Rounded to the nearest tenth of a year

Therefore the person must leave the money in the bank for 15.7 years until it reaches 7200 dollars.

Answer:

m+n = 337

Step-by-step explanation:

Lets start from the first triangle, It is given to be as 30-60-90.

The hypotenous of first rectangle be 2x, then other sides are by default x and

[tex]\sqrt{3}(x)[/tex] , using laws of trigonometry.

(sin(30) = 0.5  and cos(30) = [tex]\frac{\sqrt{3}}{2}[/tex])

The perimeter of first triangle is ,

= [tex]2x + x + \sqrt{3}(x) = x(3+\sqrt{3}) = \sqrt{3}x(1+\sqrt{3})[/tex]

Now, for second triangle, the longer leg is 2x, and similarly again,

other 2 sides are [tex]\frac{2x}{\sqrt{3}}  and \frac{4x}{\sqrt{3}}[/tex].

Again the perimeter of triangle comes out as,

= [tex]\sqrt{3}(x)(1+\sqrt{3})(\frac{2}{\sqrt{3}})[/tex]

Thus, the repeating pattern is identified. The consecutive perimeters differ by, multiplying by factor [tex]\frac{2}{\sqrt{3}}[/tex]

Thus, we can say that perimeter of 4th triangle is,

= [tex](\frac{2}{\sqrt{3}})^{3}(X)[/tex], where X is the repeating constant.

And of 12th triangle is,

= [tex](\frac{2}{\sqrt{3}})^{11}(X)[/tex],

Evaluating the above ratio, we get,

= [tex]\frac{81}{256}[/tex]

Thus, m =256 and n=81.

Thus, m+n = 256+81 = 337.

The other parallel side is 44 m

Step-by-step explanation:

Let us revise the formula of the area of a trapezium

[tex]A=\frac{1}{2}(b_{1}+b_{2})h[/tex] , where

∵ The area of a trapezium is shaped field is 480 m²

∴ A = 480 m²

∵ The distance between two parallel sides is 15 m

∴ h = 15 m

∵ One of the parallel side is 20 m

∴ [tex]b_{1}[/tex] = 20 m

We need to find [tex]b_{2}[/tex]

Substitute all these value in the rule of the area below

∵ [tex]A=\frac{1}{2}(b_{1}+b_{2})h[/tex]

∴ [tex]480=\frac{1}{2}(20+b_{2})(15)[/tex]

- Multiply the two sides by 2

∴ [tex]960=(20+b_{2})(15)[/tex]

- Divide both sides by 15

∴ [tex]64=20+b_{2}[/tex]

- Subtract 20 from both sides

∴ [tex]44=b_{2}[/tex]

The other parallel side is 44 m

Step-by-step explanation:

We will use the distributive property shown below to break it down first.

Distributive Property:  [tex]a(b-c)=ab-ac[/tex]

The expression is:

[tex]\frac{1}{2}(n-8)+7-n[/tex]

Let's distribute:

[tex]\frac{1}{2}(n-8)+7-n\\=\frac{1}{2}(n)-\frac{1}{2}(8)+7-n[/tex]

Now, we multiply:

[tex]\frac{1}{2}(n)-\frac{1}{2}(8)+7-n\\=\frac{1}{2}n-4+7-n[/tex]

Now we combine like terms (variables and numbers separately):

[tex]\frac{1}{2}n-4+7-n\\=-4+7-n+\frac{1}{2}n\\=3-\frac{1}{2}n[/tex]

This is the simplified expression.

-8 i think

Step-by-step explanation:

The y-intercept of the graph for the function y = (x - 2)(x + 4) is found by setting x to zero, which results in a y-intercept of -8.

The y-intercept on a graph represents the point where the curve or line crosses the y-axis.

To find the y-intercept of the graph of y = (x - 2)(x + 4), you need to determine the value of y when x is zero. By substituting x with 0 in the equation,

we calculate the y-intercept:

Therefore, the y-intercept of the graph is -8.

Ribbon B is [tex]\frac{11}{15}[/tex] meters long

Solution:

Given that,

Ribbon A is 1/3 meter long. It is 2/5 meter shorter than ribbon B

To find: length of Ribbon B

From given information in question,

Length of Ribbon A = [tex]\frac{1}{3} \text{ meter }[/tex]

Length of Ribbon A is 2/5 meter shorter than ribbon B

Therefore we can say,

Length of Ribbon A = length of ribbon B - [tex]\frac{2}{5}[/tex]

[tex]\frac{1}{3} = \text{ length of ribbon B } -\frac{2}{5}\\\\\text{length of ribbon B } = \frac{1}{3} + \frac{2}{5}\\\\\text{length of ribbon B } = \frac{ 5 + 6}{15} = \frac{11}{15}[/tex]

Therefore ribbon B is [tex]\frac{11}{15}[/tex] meters long
