The price of one share of Starbucks declined five dollars per day for four days in a row. How much did the price of one share change in total after the four days?

Answer:

  5x -2y = -10

Step-by-step explanation:

Slope-intercept form of the equation for a line is ...

  y = mx + b . . . . where m is the slope and b is the y-intercept.

Using the given numbers, the equation is ...

  y = 5/2x + 5

Multiplying by 2 gives ...

  2y = 5x + 10

Subtracting 2y+10 puts the equation into standard form, with positive leading coefficient and mutually prime coefficients.

  5x - 2y = -10

Answer: It's 2.2 times more expensive to buy the 12-oz can of pop compared to buying it in a 2.00 L bottle

Step-by-step explanation:

You know that:

[tex]1.00\ L = 1.057\ quarts[/tex]

[tex]1.00\ quart=32\ oz[/tex]

Then, you can make the conversion from liters to quarts:

[tex](2.00\ L)(\frac{1.057\ quarts}{1.00\ L})=2.114\ quarts[/tex]

Now, you need to make the conversion from quarts to ounces:

[tex](2.114\ quarts)(\frac{32\ 0z}{1.00\ quart})=67.648\ oz[/tex]

You know that a 12-oz can of soda pop costs 89 cents (which is $0.89). Then, the cost per ounce is:

[tex]\frac{\$0.89}{12}=\$0.074[/tex]

 And a 2.00 L bottle (67.648 oz) of the same variety of soda pop costs $2.29. The cost per ounce is:

[tex]\frac{\$2.29}{67.648}=\$0.033[/tex]

Finally, you must divide $0.074 by $$0.033:

[tex]\frac{\$0.074}\$0.033}=2.2[/tex]

Therefore, It's 2.2 times more expensive to buy the 12-oz can of pop compared to buying it in a 2.00 L bottle.

Buying soda pop in a 12-oz can is about 2.19 times more expensive per ounce than buying it in a 2.00 L bottle.

To compare the cost effectiveness of buying soda pop in different quantities, we first need to convert the volume measurements consistently:

1. Convert 2.00 L to ounces:

  Since 1.00 L = 33.8 oz (using the conversion factor 1.00 L = 1.057 quart and 1 quart = 32 oz),

  [tex]\[ 2.00 \text{ L} = 2.00 \times 33.8 \text{ oz} = 67.6 \text{ oz} \][/tex]

2. Calculate the cost per ounce for the 2.00 L bottle:

  [tex]\[ \text{Cost per ounce} = \frac{\$2.29}{67.6 \text{ oz}} \approx \$0.0339 \text{ per ounce} \][/tex]

3. Calculate the cost for the 12-oz can:

  [tex]\[ \text{Cost of 12-oz can} = \$0.89 \][/tex]

4. Compare the costs:

  [tex]\[ \text{Cost per ounce for the can} = \frac{\$0.89}{12 \text{ oz}} = \$0.0742 \text{ per ounce} \][/tex]

5. Calculate how many times more expensive the can is compared to the bottle:

  [tex]\[ \text{Times more expensive} = \frac{\$0.0742}{\$0.0339} \approx 2.19 \][/tex]

Buying a 12-oz can of soda pop costs approximately $0.0742 per ounce, while buying a 2.00 L bottle costs approximately $0.0339 per ounce. This makes the can approximately 2.19 times more expensive per ounce compared to the bottle.

What is an inequality?

The word inequality means a mathematical expression in which the sides are not equal to each other. Basically, an inequality compares any two values and shows that one value is less than, greater than, or equal to the value on the other side of the equation.

An inequality may be expressed by a mathematical sentence that uses the following symbols:

< is less than

> is greater than

≤ is less than or equal to

≥ is greater than or equal to

≠ is not equal to

Given, inequality is

40m +300 > 1000

40m > 1000-300

To find the consecutive odd integers, we need to let x represent the lesser odd integer and solve the equation x + 77 = 6(x+2). The solution is x = 13, so the lesser odd integer is 13 and the greater odd integer is 15.

Let's assume that the lesser consecutive odd integer is x and the greater consecutive odd integer is x+2.

According to the given information, 77 added to the lesser consecutive odd integer is six times the greater consecutive odd integer:

x + 77 = 6(x+2)

Solve the equation:

The lesser consecutive odd integer is 13 and the greater consecutive odd integer is 15.

Answer:

For 2 months

Step-by-step explanation:

Let after x months the cost of each health club is same,

Now, In club A,

Membership fees = $ 19,

Monthly fees = $ 21,

So, the total fees for x months = membership fees + total monthly fees for x months

= 19 + 21x

In Club B,

Membership fees = $ 23,

Monthly fees = $ 20,

So, the total fees for x months = membership fees + total monthly fees for x months

= 23 + 20x

Thus, we can write,

19 + 21x = 23 + 20x

21x - 20x = 23 - 21

x = 2

Hence, for 2 months the total cost of each health club would be same.

Answer:

Whittingham's time through the 200 m was 5.55 seconds.

Step-by-step explanation:

Huber's peed = 200m / 6.509s = 30.72m/s

1 meter per second = 3.6 km per hour

30.72 m/s =  [tex]30.72\times36.=110.6[/tex] km/hr

Sam's speed is 110.6 + 19 = 129.6 km/hr

1 km per hour = 0.2778 meter per second.

So, 129.6 km/hr = [tex]129.6\times0.2778[/tex]= 36m/s

So, Sam Whittingham's time through the 200 m was =

[tex]\frac{200}{36}= 5.55[/tex] seconds.

Final answer:

Chris Huber's average speed was 30.73 m/s. Sam Whittingham beat this by 19.0 km/h, or 5.28 m/s, totaling to an average speed of 35.01 m/s. Whittingham's time for the 200m stretch was thus approximately 5.71 seconds.

Explanation:

To calculate Sam Whittingham's time through the 200 m stretch, we first need to find Chris Huber's average speed during his record-setting ride. Huber's time was 6.509 seconds for a 200 meter stretch, giving us an average speed of 200 m / 6.509 s ≈ 30.73 m/s. Whittingham beat Huber's record by 19.0 km/h. Since 1 km/h is approximately 0.27778 m/s, a 19.0 km/h increase translates to 19.0 km/h * 0.27778 m/s/km/h ≈ 5.28 m/s. Therefore, Whittingham's average speed was 30.73 m/s + 5.28 m/s = 35.01 m/s.

To find Whittingham's time for the 200 m stretch, we divide the distance by his average speed.
Time = Distance / Speed
Time = 200 m / 35.01 m/s ≈ 5.71 seconds.

Therefore, Sam Whittingham's record-breaking time through the 200-meter distance was approximately 5.71 seconds.

Answer:

a) Δ ABC is rotated around the origin by angle 180° and then translated 1

unite to the right and 3 units up

b) R (O , 180°) and T (x + 1 , y + 3)

Step-by-step explanation:

* Lets revise some transformation

- If point (x , y) rotated about the origin by angle 180° then its image

 is (-x , -y)

- If the point (x , y) translated horizontally to the right by h units

 then its image is  (x + h , y)

- If the point (x , y) translated horizontally to the left by h units

 then its image is  (x - h , y)

- If the point (x , y) translated vertically up by k units

 then its image is  = (x , y + k)

- If the point (x , y) translated vertically down by k units

 then its image is  (x , y - k)

* Lets solve the problem

∵ Δ ABC change its place from 2nd quadrant to the 4th quadrant

  and reverse its direction Point A up and its image A" down

∵ No change in its size

∴ Triangle ABC rotates 180° clockwise around the origin

# Remember : There is no difference between rotating 180° clockwise

  or  anti-clockwise around the origin

∵ The vertices of Δ ABC are:

# A = (-3 , 5)

# B = (-3 , 2)

# C = (-1 , 2)

∵ If point (x , y) rotated about the origin by angle 180° then its image

 is (-x , -y)

∴ A'' = (3 , -5)

∴ B'' = (3 , -2)

∴ C'' = (1 , -2)

∴ Triangle ABC rotates 180° around the origin to form ΔA"B"C"

∵ The vertices of Δ A'B'C are:

# A' = (4 , -2)

# B' = (4 , 1)

# C' = (2 , 1)

- By comparing the x-coordinates and y-coordinates of points of

 Δ A''B''C'' and Δ A'B'C' we will find that every x-coordinate add by 1

 and every y-coordinate add by 3

∵ 4 - 3 = 1 and 2 - 1 = 1 ⇒ x- coordinates

∵ -2 - (-5) = -2 + 5 = 3 and 1 - (-2) = 1 + 2 = 3 ⇒ y-coordinates

∴ ΔA''B''C'' translates to the right 1 unite and up 3 units to form

  Δ A'B'C'

a) Δ ABC is rotated around the origin by angle 180° and then

   translated 1 unite to the right and 3 units up

b) R (O , 180°) and T (x + 1 , y + 3)

Answer:

y - 1 = -4(x - 7).

Step-by-step explanation:

Point-slope equation is:

y - y1 = m(x - x1)  where m = the slope and (x1, y1) is a point on the line.

Here m = -4 , x1 = 7 and y2 = 1, so:

y - 1 = -4(x - 7).

An equation of the line in point-slope form is: D. y - 1 = -4(x - 7).

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

x and y represent the data points.

m represent the slope.

At data point (7, 1) and a slope of -4, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 1 = -4(x - 7)

Hi Jakeyriabryant! I hope you’re fine!

I hope I have understood the problem well.

If so, what the exercise raises is the following equality:

(x-1) / 5 = 2/3

From this equation you must clear the "x".

First, we pass the 5 that is dividing on the side of the x, to the other side and passes multiplying

(X – 1) / 5 = 2/3  

(X – 1) = (2/3)*5

X – 1 = 10/3

Then we pass the one that is subtracting from the side of the x, to the other side and passes adding

X  = 10/3 + 1

Remember that to add or subtract fractions they must have the same denominator or a common denominator (in this case we can write 1 as fraction 3/3). Then,

X = 10/3 + 3/3

X = 13/3

I hope I've been helpful!

Regards!

The solution to the equation 2/3 = (x-1)/5 is x = 13/3. This is achieved by cross-multiplying, then isolating x.

To solve for x in the equation 2/3 = (x-1)/5, you will need to isolate the variable 'x'. This requires you to perform the same mathematical operation on both sides of the equation in order to maintain balance. Here we have a situation that involves proportions. Solve it by cross-multiplying:

When observed, the given scatter plot has one cluster and one outlier.

Hence, option A) is the correct answer.

Approximately [tex]\(8.51 \times 10^8\)[/tex] ice cream cones are purchased in one year, given a rate of 1.7 thousand cones per minute over [tex]\(5.3 \times 10^5\)[/tex] minutes.

To find the total number of ice cream cones purchased in one year, we can multiply the rate of purchase per minute by the total number of minutes in a year.

Given: Purchase rate = 1.7 thousand ice cream cones per minute, and there are [tex]\(5.3 \times 10^5\)[/tex] minutes in a year.

[tex]\[ \text{Total cones in one year} = \text{Rate per minute} \times \text{Minutes in a year} \][/tex]

[tex]\[ \text{Total cones} = 1.7 \times 10^3 \, \text{cones/minute} \times 5.3 \times 10^5 \, \text{minutes} \][/tex]

Now, multiply the coefficients and add the exponents:

[tex]\[ \text{Total cones} = 8.51 \times 10^8 \, \text{ice cream cones} \][/tex]

Therefore, approximately [tex]\(8.51 \times 10^8\)[/tex] ice cream cones are purchased in one year.

Final answer:

By multiplying 1.7 × 10³ cones per minute by 5.3 × 10⁵ minutes per year, the total number of cones purchased in one year is approximately 9.01 × 10⁸ cones.

Explanation:

To calculate the total number of ice cream cones purchased in one year, we can use scientific notation and multiplication. First, convert the number of ice cream cones bought per minute into scientific notation:

1.7 thousand cones per minute = 1.7 × 10³ cones/minute

Next, multiply this by the total number of minutes in a year, also given in scientific notation:

5.3 × 10⁵ minutes/year

The calculation will look like this:

(1.7 × 10³ cones/minute) × (5.3 × 10⁵ minutes/year) = (1.7 × 5.3) × (10³× 10⁵) = 9.01 × 10⁸ cones/year

The approximation for the number of cones purchased in one year is 9.01 × 10⁸ cones.

3/4r + 1/2(r+6)=23

3/4r + 1/2r +3=23

5/4r =20

Multiplying by 45 yields r=16

DaMarcus's speed is r=16 miles per hour & Fabian's speed is r+6=22 miles per hour.

Speed of demarcus is 16 mph & speed of fabian is 22 mph.

The rate of change of position of a particle with respect to time is called speed of that particle.

Distance = Speed × time

Let, Demarcus rides x mph for 3/4th of an hour i.e. 0.75 hour

So, he rode 0.75x miles

Given that, Fabian's speed is 6 mph more than Demarcus's speed.

Fabian rides (x+6) mph for half an hour, i.e. 0.5 hour

So, he rode 0.5(x+6) miles

According to the question,

0.75x+0.5(x+6) = 23

⇒ 0.75x+0.5x+3=23

⇒ 1.25x = 20

⇒ x = 20/1.25

⇒ x = 16 mph

So, Demarcus's speed is 16 mph

Answer:

k = Y*A/L

Step-by-step explanation:

We can apply the Law of Hooke in order to explain the problem.

If we define k = F / ΔL  and the Y = S / δ

Where S is the uniaxial stress: S =  F / A   (i)

and δ is the strain: δ = ΔL / L   (ii)

ΔL is the change in length

we can combine the equations i and ii as follows

Y = (F / A) / (ΔL / L) = (F * L) / (A * ΔL)   (iii)

if k = F / ΔL the equation iii results

Y = k * (L / A)  ⇒   k = Y*(A / L)

The spring constant of a metal bar for low values of tensile strain can be determined using Hooke's Law. It is given by the formula k = (A * Y) / L, where A is the cross-sectional area, Y is the Young's modulus of the material, and L is the initial length of the bar.

The 'spring constant' of a metal bar for low values of tensile strain can be determined using Hooke's Law, which relates the applied force to the resulting elongation. In this case, the elongation is equivalent to the tensile strain.

Therefore, the spring constant of a metal bar for low values of tensile strain is

k = (A * Y) / L
