Answer 1

The constant of proportionality in terms of the cost per text is the coefficient of [tex]t[/tex] in the equation [tex]b=0.25t[/tex]. Since the coefficient of [tex]t[/tex] is 0.25, the constant of proportionality in terms of the cost per text is 0.25.
Proportionality constants are usually expressed as fractions, so lets convert 0.25 to a fraction. To do that we are going to add the denominator 1 to our decimal, and then we will multiply both numerator and denominator by ten for every number after the decimal point:
[tex] \frac{0.25}{1} [/tex]
[tex] \frac{0.25}{1} . \frac{100}{100} = \frac{75}{100} [/tex]
Finally, we can simplify our fraction:
[tex] \frac{25}{100} = \frac{1}{4} [/tex]

We can conclude that the constant of proportionality in text of the cost per text is 1/4

Find the sum. 13(9−6m)+14(12m−8)

Answers

Final answer:

To solve the expression 13(9−6m)+14(12m−8), distribute the numbers and combine like terms to get the sum, which is 90m + 5.

Explanation:

To find the sum of the expression 13(9−6m)+14(12m−8), we need to distribute the numbers outside the parentheses across the terms inside the parentheses and then combine like terms.

Distribute the numbers:

13 × 9 = 117

13 × (−6m) = −78m

14 × 12m = 168m

14 × (−8) = −112

Now we combine like terms:

117 (−78m) + (168m − 112)

Simplifying this we get:

−78m + 168m = 90m

−112 + 117 = 5

So the sum is 90m + 5.

Mrs. Bowen told Mr. Bowen that there is no way he is way he is spending that much money on golf clubs. instead she wants to buy a new flat screen television for the living room. Walmart has a 55 inch ultra slim HDTV flat screen that is normally $1099.99 but its on sale for 42% off. The sales tax on the TV will be 6.5%. How much will the final price of the TV be?
Can you please explain how to do it?

Answers

Hi there!
Sounds confusing, I know.

But let me try to explain.
First we need to subtract the discount from the total.

1099.99- 42%= 637.99

So, 637.99 is our new total, but wait!
We have to add the SALES TAX!! That’s kind of important. ; )

Okay so now let’s take our new total and then add the tax.

637.99+ 6.5%= 679.45

And... there we have it. $679.45 for that beautiful flat screen tv.
Looks like the Bowen’s are in for some big savings! Maybe they can buy those golf clubs after all...

Have a terrific day! I hope I have successfully helped you.

If y is 12 when x is 15 that means that x is 3 more than y. x=y+3 so when y is 21, x=21+3 so x=24

A wire is stretched from the top of an 8 ft. pole to a bracket 5 ft. from the base of the pole. How long is the wire?

Answers

pathagorean theorem:
[tex] {a}^{2} + {b}^{2} = {c }^{2} \\ {8}^{2} + {5}^{2} = {c}^{2} \\ 64 + 25 = {c}^{2} \\ 89 = {c}^{2} \\ \sqrt{89 } = \sqrt{ {c}^{2} } \\ the \: wire \: is \: 9.43ft[/tex]

The length of the stretched wire is required.

The length of the wire is 9.43 feet.

Pythagoras theorem

b = Length of the pole = 8 ft

a = Distance between bracket and base of pole = 5 ft

c = Length of wire

The two lengths form a right triangle.

From the Pythagoras theorem we have

Suppose one third of each of 5 same sized posters is covered with opaque paper.What fraction of the posters are Not covered by opaque paper?Explain how to use multiplication to find what part of the posters are not covered by opaque paper?

Answers

Final answer:

Two-thirds of each poster are not covered with opaque paper. Multiplying (2/3) by 5 gives us 10/3, which can be converted to 3 and 1/3, indicating that three whole posters plus one-third of another are not covered.

Explanation:

If one third of each of 5 same sized posters is covered with opaque paper, then two thirds of each poster are not covered. To find what fraction of the posters are not covered by opaque paper, you apply multiplication. You start with one poster: one-third covered means two-thirds are not covered. Represent this as 2/3. Since the question concerns 5 identical posters, you multiply the fraction of one poster (2/3) by the number of posters (5).

Mathematically, this looks like:

(2/3) × 5 = 10/3

However, 10/3 represents more than one whole, and it can be converted into a mixed number to represent the total unobstructed fraction of the posters. This is 3 and 1/3, meaning that in total, you have three whole posters and one-third of another poster not covered by opaque paper.

The population of a city in 2005 was 18000. By 2010, the city’s population had grown to 45,000. Economists have determined that the growth is exponential. If they are correct, what is the projected population for 2015?

Answers

first do 45000-18000=27,000
and approx projected population is 45,000+18000=63,000
your answer is 63,000

Solution:

we are given that

The population of a city in 2005 was 18000.

By 2010, the city’s population had grown to 45,000.

Economists have determined that the growth is exponential.

As we know the exponential growth is defined by the relation

[tex]P=p_0e^{rt}\\ \\ \text{where P is the population at time t and initial population is } p_0\\[/tex]

Here we have [tex]p_0=18000, P=45000, t=5[/tex]

substitute these values we get

[tex]45000=18000e^{5r}\\ \\ r=0.183[/tex]

So we get

[tex]P(t)=18000e^{0.183t}[/tex]

So For population is 2015 substitute t=10

[tex]P(10)=18000e^{0.183*10}[/tex]

[tex]P(10)=112209.9598 [/tex]

The projected population for 2015 is 112210

Rewrite the following equation in slope-intercept form. 19x − 20y = -13 Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Y= 0

19x = -13
X= -13/19

X=0

-20y=-13
Y= 13/20

Final answer:

To rewrite the equation 19x - 20y = -13 in slope-intercept form, you subtract 19x on both sides and then divide by -20 to isolate y. The resulting equation is y = (19/20)x + 13/20.

Explanation:

To rewrite the equation 19x - 20y = -13 in slope-intercept form, follow these steps:

Move 19x to the other side by subtracting it from both sides: -20y = -19x - 13

Divide by -20 to isolate y: y = (19/20)x + 13/20

Therefore, the equation in slope-intercept form is y = (19/20)x + 13/20.

Nathan has a sculpture in the shape of a pyramid. The height of the sculpture is 3 centimeters less than the side length, x, of its square base. Nathan uses the formula for the volume of a pyramid to determine the dimensions of the sculpture:

Here, a is the side length of the pyramid’s square base and h is its height.

If 162 cubic centimeters of clay were used to make the sculpture, the equation x3 +
x2 +
= 0 can be used to find that the length of the sculpture’s base is
centimeters.

Answers

Final answer:

The student needs to apply the formula for the volume of a pyramid, V = 1/3 * a² * h. Since the height is 3 cm less than the side length, this introduces a variable in the equation, (x - 3), to solve for x.

Explanation:

The question relates to pyramid volume and the formulation of mathematical equations. First, it requires understanding that the volume of a pyramid is derived using the formula V = 1/3 * a² * h, where V is the volume, a is the length of the side of the square base, and h is the height of the pyramid. Since the height is stated as 3 cm less than the base (x), we can interpret this in the formula as h = x - 3.

Replacing these values in the volume formula gives us V = 1/3 * x² * (x-3). As the volume given is 162 cubic centimeters, this forms the equation: 162 = 1/3 * x² * (x-3). Simplifying this equation would provide the base length x in cm.

Leon works at a grocery store for $8 an hour. He also mows lawns for $10 an hour. He needs to earn at least $120 per week, but he does not want to work more than 20 hours per week. Use a system of inequalities to find a possible combination of hours he can work at the grocery store and mowing lawns in order to meet his goal.

Answers

You could do 10 hours of mowing and 5 hours at the store. He would work at both places for one hour. number of hours = 140

Answer:

The data we have is:

He works for $8 an hour.

He mows lawns for $10 an hour.

He wants to work no more than 20 hours per week, and wants to hearn at least $120 week.

So if S is the number of hours he works in the store, and M is the number of hours that he mowns lawns, we have the inequalities:

S + M ≤ 20

S*$8 + M*$10 ≥ $120

So let's choose a possible solution:

Let's select M = 12 and S = 0

in this way, he worsk

0h + 12 h = 12 h that is less than 20 hours, and he wins:

0*$8 + 12*$10 = $120, which is the minimum amount of money that he wants to win.

and we have a lot of other possible solutions:

S= 1, M = 12

S = 2, M= 12.. and so on.

And [tex]\overline{RS}=59\text{ and }\overline{ST}=10x-31[/tex]

Since, we know that congruent arcs have congruent chords.

Therefore, [tex]\overline{RS}=\overline{ST}[/tex]

[tex]59=10x-31\\\\\Rightarrow\ 10x=59+31\\\\\Rightarrow 10x=90\\\\\Rightarrow x=\frac{90}{10}\\\\\Rightarrow x=9[/tex]

To solve the problem we must know the Chord's Equidistant From The Center Of A Circle Theorem.

Equidistance chords

If two chords of a circle are equidistant from the center then they are congruent to each other and their corresponding arcs are also congruent.

The value of x is 9.

Given to usRS = 59,ST = 10x-31,

In circle,

Chord RS and chord ST are equidistant from the center. therefore,

RS = ST

[tex]59 = 10x-31\\ 59+31 = 10x\\ 90 = 10x\\\\ x= \dfrac{90}{10}\\\\ x= 9[/tex]

vivien's handspan measure 18.5 centimeters.estimate the number of times Vivien uses her handspan to measure a length of 1 meter 75 centimeters

Answers

1.75 meters is 175 centimeters
Estimate what is 175 ÷ 18.5 . It cant be 10 because 18.5 is 185 which is greater than 175 , so lets estimage Vivien will have to use her handspan 9 times.

Final answer:

Vivien would use her handspan, which measures 18.5 centimeters, approximately 9 times to measure a length of 1 meter 75 centimeters. This estimate assumes precision in her handspan measurement.

Explanation:

To estimate the number of times Vivien uses her handspan to measure a length of 1 meter 75 centimeters, we need to divide the total length by the length of her handspan. Since Vivien's handspan measures 18.5 centimeters, and the total length to measure is 1 meter 75 centimeters (which equals 175 centimeters), we perform the following calculation:

Convert 1 meter 75 centimeters to all centimeters: 1 meter = 100 centimeters, so 1 meter 75 centimeters = 100 + 75 = 175 centimeters.Divide the total length by the length of Vivien's handspan: 175 cm/18.5 cm =9.45945945945946Round the result to the nearest whole number to estimate the number of handspans: approximately 9 times (since we typically round down when the decimal is less than 0.5).

This is an estimation technique that assumes Vivien's measurement with her handspan is accurate. The accuracy of this measurement can vary based on several factors, including the precision of Vivien's handspan and the method used for measuring.
