1. Let x = #

2. "Five less than six times a number" can be written as: 6x - 5

3. "is at least" is the same as "greater than or equal to" and can be written as: >=

4. "nine subtracted from two times that number" can be written as: 2x - 9

5. the equation is: 6x - 5 >= 2x - 9

6. solve for x by grouping the x variable terms on one side and the constants on the other side:

6x - 5 >= 2x - 9

-2x +5 -2X +5

4x >= -4

7. divide each side by 4, and you get: x = -1

Slope 1,passes through (2,5)
Write equation in slope intercept form

Answers

Answer:

all work is pictured and shown

Final answer:

The equation of a line with a slope of 1 that passes through the point (2,5) in slope-intercept form is y = x + 3.

Explanation:

To write the equation of a line in slope-intercept form (y = mx + b), you need to know the slope (m) and the y-intercept (b). Since the slope is given as 1 and the line passes through the point (2,5), we can use the point-slope formula to find the y-intercept.

The point-slope formula is y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point the line passes through. Plugging in the values we have:

y - 5 = 1(x - 2) → y - 5 = x - 2 → y = x + 3

So, the equation of the line in slope-intercept form is y = x + 3.

What is an equation of the line that passes through the point (-2,3) and is parallel to the line whose equation is y=3/2x-4?​

Answers

Answer:

Step-by-step explanation:

We can model a line with slope-intercept form:

[tex]y = mx + b[/tex]

where [tex]m[/tex] is the slope and [tex]b[/tex] is the Y-intercept.

We know that the new line is parallel to the given line, so the two lines have the same slope, or [tex]m = \frac{3}{2}[/tex]:

[tex]y = \frac{3}{2}x + b[/tex]

To determine [tex]b[/tex], we just need to plug in the given point that the line passes through, [tex](-2, 3)[/tex]:

[tex]y = \frac{3}{2}x + b[/tex]

[tex](3) = \frac{3}{2}(-2) + b[/tex]

[tex]3 = -3 + b[/tex]

[tex]b = 6[/tex]

This gives us the following equation:

[tex]y = \frac{3}{2}x + 6[/tex]

The equation of the line is y = (3/2)x + 6.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of the line passes through the point (-2,3).

y = m(1)x + c

The equation of the line is parallel to the line whose equation is y=3/2x-4.

​This means,

y = (3/2)x - 4

This is in the form of y = m(2)x + c

m(2) = (3/2)

So,

m(1) = m(2)

Now,

(-2, 3) = (x, y)

y = m(1)x + c

3 = (3/2) x (-2) + c

3 = -3 + c

c = 3 + 3

c = 6

Now,

y = m(1)x + c

y = (3/2)x + 6

Thus,

The equation of the line is y = (3/2)x + 6.

A band is performing at an auditorium for a fee of $1500. In addition to this fee, the band receives 30% of

a. Write an equation that represents the band's revenue R when x tickets are sold.

An equation is R=

B. The band needs 5000 for new equipment so how many tickets need to b sold in order to get enough koney to buy the equipment.

Answers

Answer:

A. [tex]R=1,500+6x,\ x\le 800[/tex]

B. 584

Step-by-step explanation:

A band is performing at an auditorium for a fee of $1500.

In addition to this fee, the band receives 30% of each $20 ticket sold. Let x be the number of tickets sold, then these x tickets cost $20x. Calculate 30% of 20x:

[tex]20x\cdot 0.3=6x[/tex]

A. The total cost is

[tex]R=1,500+6x[/tex]

The maximum capacity of the auditorium is 800 people, so x≤800.

B. The band needs $5,000 for new equipment so

[tex]1,500x+6x\ge 5,000\\ \\6x\ge 3,500\\ \\x\ge \dfrac{3500}{6}\\ \\x\ge 583.333...[/tex]

So, it is enough 584 tickets to be sold.

The band's revenue equation is R = 1500 + 0.30 * 20 * x. To earn $5000 for new equipment, the band needs to sell at least 584 tickets, considering their fixed fee and the additional revenue from ticket sales.

Calculating Revenue for a Band's Performance

The band's total revenue (R) when x tickets are sold can be calculated using the equation: R = 1500 + 0.30 *20* x. This equation includes their fixed fee of $1500 plus the variable amount obtained from ticket sales, which is 30% of the ticket price ($20). For every ticket sold, the band adds $6 (30% of $20) to their revenue.

For the band to afford new equipment costing $5000, we need to determine how many tickets need to be sold. The equation becomes:

R = 1500 + 0.30 * 20 * x

$5000 = 1500 + 6 * x

$5000 - 1500 = 6 * x

$3500 = 6x

x = $3500 / 6

x = 583.33

Since the band cannot sell a fraction of a ticket, they would need to sell at least 584 tickets to meet their goal of $5000.

6. You cut a styrofoam ball in half for a project. Find the surface area of each half of the styrofoam ball. (Round your answer to two decimal places.)

Answers

Answer: [tex]2,412.74\ cm^2[/tex]

Step-by-step explanation:

You need to use the following formula for calculate the Total surface area of a solid hemisphere:

[tex]SA_{total}=3\pi r^2[/tex]

Where "r" is the radius.

 Since you cut a styrofoam ball in half, the total surface areas are equal.

The exercise gives you the diameter. Observe in the figure that this is:

[tex]d=32\ cm[/tex]

Since the radius is half the diameter, you know that:

[tex]r=\frac{d}{2}\\\\r=\frac{32\ cm}{2}\\\\r=16\ cm[/tex]

Finally, you can substitute the radius into the formula:

 [tex]SA_{total}=3\pi (16\ cm)^2=2,412.74\ cm^2[/tex] (Of each half of the styrofoam ball)

You can use the fact that along with the surface area of hemisphere, you need to add the surface area of the circle that's on the top of each hemisphere.(hemisphere means half of sphere)

The surface area of each half of the styrofoam ball is [tex]3\pi r^2 \: \rm unit^2[/tex]

What is the surface area of a hemisphere?

Surface area of sphere = [tex]4 \pi r^2[/tex] sq. units where r is radius of sphere.

Since hemisphere is half of the sphere, thus,

Surface area of hemisphere = [tex]2\pi r^2[/tex] sq. units.

Using the above formula along with the area of circle to find the needed surface area

Since the foam ball is not hollow, if we slice it in half, each of the half piece is having surface = outer half sphere's surface + that circle which is formed due to slicing the ball

Thus, surface area of each half of the Styrofoam ball is calculated as

Surface area = Surface area of hemisphere + area of circle

Let the ball had radius r, then we have the needed surface area as:

[tex]S = 2\pi r^2 + \pi r^2 = 3\pi r^2 \: \rm unit^2[/tex]

S is surface area of each half of the styrofoam ball.

Answers

Answer:

1.  0.8 cm

2.  1.6 cm

Step-by-step explanation:

1.

The scale for 2nd map is 1 cm to 50 km, that means "1 cm on map" is "50 km in real life".

We already know distance from Cleveland to Cincinnati is 40 km, which is less than 50, so we know the distance on map would be less than 1 cm.

So we set up ratio and figure out (let x be distance on map from Cleveland to Cincinnati):

[tex]\frac{1}{50}=\frac{x}{40}\\50x=40\\x=\frac{40}{50}\\x=0.8[/tex]

Hene, 0.8 centimeters would be the distance in 2nd map

2.

A scale of 1:50 means 1 cm equal 50 cm

So, 0.8m would be

0.8 * 100 = 80 cm

Hence, 80 cm would be represented by 80/50 on the map, that is:

[tex]\frac{80}{50}=1.6[/tex]

That is 1.6 centimeters

Draw a rectangle with six regions to expand (2x + 4) (3x2 + 5x + 7).

Answers

To expand (2x + 4) (3x^2 + 5x + 7), draw a rectangle with six regions, multiply the terms in each region and add them together. The final expanded form is 6x^3 + 22x^2 + 34x + 28.

To expand the polynomial expression (2x + 4) (3x2 + 5x + 7), we will use the rectangle (or area) method. This involves drawing a rectangle divided into six regions, each representing a product of a term from the first binomial and a term from the second trinomial.

First, draw a 2x3 rectangle, with the dimensions representing the two terms in the first binomial and the three terms in the second trinomial.

Label the length of the rectangle with the three terms from the second trinomial, 3x2, 5x, and 7.

Label the width of the rectangle with the two terms from the first binomial, 2x and 4.

Fill in each of the six regions by multiplying the term at the end of the row by the term at the top of the column. For example, the top-left region would be 2x multiplied by 3x2, giving 6x3.

Continue filling in the other five regions: 2x times 5x is 10x2, 2x times 7 is 14x, 4 times 3x2 is 12x2, 4 times 5x is 20x, and 4 times 7 is 28.

a taxi charges $1.75 for the first 1/8 mile and $0.30 for each additional 1/8 mile write an equation that gives the cost c of a taxi ride in terms of the number of miles m how many miles did you drive if a ride cost $7.75

Answers

Final answer:

The cost of a taxi ride can be calculated using the equation c = 1.75 + (m - 1/8) * 8 * 0.30, where c represents the total cost and m represents the total miles driven. Solving this equation for m when the total cost is $7.75 would yield the number of miles driven.

Explanation:

The subject of this question is the creation of an equation to calculate the cost of a taxi ride. According to the question, a taxi charges $1.75 for the first 1/8 mile and $0.30 for each additional 1/8 mile. First, we need to convert miles to 1/8 miles, since the pricing is based on this fraction. We know that each full mile is equal to 8 fractions of 1/8 mile. Therefore, to convert miles to 1/8 miles, we multiply the number of miles by 8.

Given this pricing structure, the costs associated with additional miles driven beyond the first 1/8 mile (which are already accounted for by the initial $1.75), can be represented by (m-1/8)*8*0.30. Here, (m-1/8) represents the additional miles traveled beyond the first 1/8 mile, and multiplying this by 8 converts these miles into 1/8 miles.

The total cost, c, can thus be represented by the equation c = 1.75 + (m - 1/8) * 8 * 0.30. If a ride cost $7.75, we can substitute this cost into the equation and solve for m to find the number of miles driven. This would give us the equation: 7.75 = 1.75 + (m - 1/8) * 8 * 0.30.

The shorter the wavelength, thethe frequency.greater1 smallerU stronger The horn on a commuter train emits sound with a frequency of 342.5 Hz when the train is at rest. The train sounds its horn as it passes a passenger platform at a constant speed of 41 m/s. What overall change in frequency is detected by a person on the platform as the train moves from approaching to receding? Remember that change of frequency means the final frequency minus the initial frequency. Be sure to include the correct sign on the answer. (Take the speed of sound to be 345 m/s.) Using the digits 0 through 9, find out how many 4-digit numbers can be configured based on the stated conditions: a. [1 pt] The number cannot start with zero and no digits can be repeated. b. [1 pt] The number must begin and end with an odd digit. (Repeated digits are okay.) c. [1 pt] The number must be at least 5000 and be divisible by 10. (Repeated digits are okay.) d. [2 pt] The number must be less than 3000 and must be even. No digits may be repeated in the last 3 digits. (That is, 2234 would be okay, but 2334 would not be okay.) While following a treasure map, you start at an old oak tree. You first walk 825 m directly south, then turn and walk 1.25 km at 30.0 west of north, and finally walk 1.00 km at 32.0 north of east, where you find the treasure: a biography of Isaac Newton! (a) To return to the old oak tree, in what direction should you head and how far will you walk? Use components to solve this problem. (b) To see whether your calculation in part (a) is reason- able, compare it with a graphical solution drawn roughly to scale. The rules of the game are as following: a player draws one card from a standard 52-card deck. If the player picks a heart, they win $10. If they pick a face card that is not a heart, the player wins $8. Picking a face card heart counts the same as picking a heart. If a player picks another card, they lose $6.

She told her classmates that she noticed her cupcakes were moister and even taller. She said she measured each cupcake and the ones made with 3 eggs instead of two were 0.25-.05 centimeters taller than the ones with only 2 eggs. She also said that the ones with more eggs seemed to be a darker shade than the ones with fewer eggs. Jamie said the amount of eggs didnt affect how many cupcakes she could make. She was only able to get 6 jumbo sized cupcakes with the recipe even if she added an extra egg. Question: List at least 2 qualitative and 2 quantitative observations that Jamie made in her experiment.
