Gas prices in Cook county are at $3.30 per gallon. If a market scientist predicts a 20% increase in the price of gas in the coming month, what will the price of gas be?

Answers

Answer 1

3.30*1.2=3.96
$3.96 will be the new price of gas

Answer 2

The price of the gas is $3.96.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Gas prices in Cook-County are at $3.30 per gallon.

If a market scientist predicts a 20% increase in the price of gas in the coming month,

that means,

100 + 20% = 120% increase = 1.2 in decimals.

The price of gas,

= 3.30 + 3.30 x 1.2

= 3.96

Therefore, the new price is $3.96.

Answers

The answer is 13. To figure this out I used 10 notebooks sold as a guide. I knew the answer could not be 10, because $27.95/10 was not a number stopping in the hundredths place (or a true money amount).

I tried numbers greater than 10 using a trial and error strategy until I got to 13 notebooks sold and found that it $27.95 was divisible by 13 to get an answer between $2 and $3 ($2.15 exactly).

Rhono has a part-time job at the local supermarket working 3 hours after school each night and 5 hours on saturdays. His gross hourly pay is $8.75. Estimate and then calculate his next wages for the month, after 20% tax is deducted. Each month his expenses are: Entertainment $35.00, health and beauty $21.00, transport $18.00, clothing $24.00, hire purhases payments $15.75. Calculate the amount Rhono has left over at the end of each month, and how much he would have saved at the end of 12 months.

Answers

Rhono apparently works 5*3+5 = 20 hours per week. His net pay for 4 weeks* is
.. 4*20*8.75*(1 -0.20) = $560

The listed expenses add to
.. 35 +21 +18 +24 +15.75 = 113.75

The amount left over at the end of each 4-week period is
.. $560 -113.75 = $446.25

If he saves the remainder, after 12 months, he will have saved
.. 12*$446.25 = $5,355.00

___
* There are 13 periods of 4 weeks in a year. If Rhono takes no vacation, his savings balance may be $560 more than the above amount, that is, $5,915.00.

Rhono earns a net monthly pay of $560.00 after taxes, with monthly expenses totaling $113.75. This leaves him with $446.25 per month, resulting in a total savings of $5,355.00 at the end of 12 months.

Let's calculate Rhono's monthly wages first.

Rhono works:

- 3 hours each night after school

- 5 hours on Saturdays

His gross hourly pay is $8.75.

To calculate his monthly wages, we need to find his total hours worked per month.

In a week, he works 3 hours × 5 days from Monday to Friday and 5 hours on Saturday,

which totals 15 hours + 5 hours

= 20 hours per week.

In a month (considering approximately 4 weeks per month), he works 20 hours × 4 weeks

= 80 hours per month.

Now, let's calculate his gross monthly income before tax deductions:

Gross monthly income = hourly wage × total hours worked per month

Gross monthly income = 8.75 × 80

Gross monthly income = $700

Now, let's calculate the amount of tax that will be deducted.

Rhono's gross monthly income is $700, and 20% of this will be deducted.

Tax deduction = 0.20 × 700

Tax deduction = 140

Now, let's calculate his total monthly expenses:

Total monthly expenses = 35.00 + 21.00 + 18.00 + 24.00 + 15.75

Total monthly expenses = $113.75

Now, let's calculate the amount Rhono has left over after tax and expenses:

Net monthly income = Gross monthly income - Tax deduction - Total monthly expenses

Net monthly income = 700 - 140 - 113.75

Net monthly income = $446.25

This is the amount Rhono has left over at the end of each month.

To calculate how much he would have saved at the end of 12 months, we multiply this amount by 12:

Total savings after 12 months = 446.25 × 12

Total savings after 12 months = $5,355

So, Rhono would have saved $5,355 at the end of 12 months.

Which is a true statement about the diagram? m∠5 + m∠6 = m∠1 m∠3 + m∠4 + m∠5 = 180° m∠1 + m∠2 = 180° m∠2 + m∠3 = m∠5

Answers

m<1 +m<2 = 180° is the answer

Answer:

Third option is the right choice.

Step by step explanation:

We have been given an diagram and we are asked to choose the true statement about the diagram.

Let us see our all choices one by one.

1. [tex]m\angle5+m\angle6=m\angle1[/tex]

We can see that [tex]\angle5[/tex] and [tex]\angle6[/tex] are supplementary and there measure should be equal to 180 degrees. [tex]\angle1[/tex] is exterior angle of our triangle and its measure must be equal to sum of measures of [tex]\angle5[/tex] and [tex]\angle3[/tex].

Therefore, 1st option is incorrect.

2. [tex]m\angle3+m\angle4+m\angle5=180^{o}[/tex]

We can see that [tex]\angle3[/tex] and [tex]\angle4[/tex] are supplementary and they must be equal to 180 degrees. Therefore, 2nd option is also incorrect.

3. [tex]m\angle1+m\angle2=180^{o}[/tex]

We can see from our diagram that [tex]\angle1[/tex] and [tex]\angle2[/tex] are supplementary. Therefore, 3rd option is the correct choice.

4. [tex]m\angle2+m\angle3=m\angle5[/tex]

We can see that [tex]\angle2[/tex], [tex]\angle3[/tex] and [tex]\angle5[/tex] are interior angles of our triangle and their measure should be equal to 180 degrees. By exterior angle theorem sum of measures of [tex]\angle2[/tex] and [tex]\angle3[/tex] will be equal to measure of [tex]\angle6[/tex] instead of [tex]\angle5[/tex].

Therefore, our 4th option is also incorrect.

Ms. Romero is buying a scrapbook and sheets of designer paper. She has $30 and needs at least $15.75 to buy the scrapbook. Each sheet of paper costs $0.29. 30−0.29x≥15.75 to find the number of sheets of paper, x, she can buy. How many sheets of paper can she buy?

Answers

we need to solve the inequality to find what x could be
solving inequalities is similar to solving unknowns in an equation, the same set of steps are followed, except that x could be equal to the final answer or more or less than that value depending on the sign .
30−0.29x ≥ 15.75
-0.29x ≥ -14.25
when dividing by a negative number (-0.29) the inequality side should change its direction
In this case ≥ changes to ≤
x ≤ -14.25/-0.29
x ≤ 49.13
since they are asking for number of sheets of paper it should be the nearest whole number that is less than or equal to 49.13
since 49.13 is not a whole number we should round it off to the nearest whole number that is less than that.
x ≤ 49
she can buy maximum 49 sheets of paper and have enough money to buy the scrapbook.
49 x $ 0.29 + 15.75 = 14.21 + 15.75 = $29.96

Ms. Romero can buy up to 49 sheets of paper.

To determine the number of sheets of paper $ x $ that Ms. Romero can buy, we start with the inequality:

[tex]\[ 30 - 0.29x \geq 15.75 \][/tex]

First, isolate the term involving $ x $ by subtracting 15.75 from both sides:

[tex]\[ 30 - 15.75 \geq 0.29x \][/tex]

Simplify the left side:

[tex]\[ 14.25 \geq 0.29x \][/tex]

Next, solve for $ x $ by dividing both sides by 0.29:

[tex]\[ \frac{14.25}{0.29} \geq x \][/tex]

Calculate the value:

[tex]\[ x \leq \frac{14.25}{0.29} \]\[ x \leq 49.13793103448276 \][/tex]

Since $ x $ must be a whole number, we take the greatest integer less than or equal to 49.13793103448276, which is 49. Therefore, the maximum number of sheets of paper she can buy is:

[tex]\[ x = 49 \][/tex]

Thus, Ms. Romero can buy up to 49 sheets of paper.

The perimeter of a rectangle is twice the sum of length and width, so the sum of length and width is 360 meters.

360 m - 160 m = 200 m

The width of the garden is 200 meters.

_____
Of course, you know that 1 km = 1000 m, so 0.72 km = 720 m.

Hello!

In order to find the answer to the question, we can begin by converting the measurements into one common unit. In this case, we can convert 0.72km to 720 meters, which will make the final calculation a bit easier.

The formula to find the perimeter of the garden is L2+W2.

The length is 160 meters, so we can multiply this by two to find a portion of the rectangle.

160 x 2 = 320

Now, we can subtract 320 from the total number: 720

720 - 320 = 400

To find the width, we simply now need to divide 400 by 2.

[tex] \frac{400}{2} [/tex] = 200

The width of the garden is 200 meters.

the city is planning to build a new park by enlarging the current park by a scale factor of 4. The current park has an area of 37,625 yd squared. what is the area of the new park

Answers

The new area would be 602,000 yd².

When you enlarge a shape (or a park) by a factor, you are multiplying the length of its sides by that factor. In this case, we are multiplying its length and width by 4.

Let l be the old length and w be the new length. The old area would be given by A=lw.

Enlarging this by a factor of 4 would make the new length 4l and the new width 4w. The new area would be 4l(4w)=16lw. The new area is 16 times larger than the old area, so:

37,625(16)=602,000.

Multiply x^2-8x+15/3x * 8x/x-3

Answers

You must follow the steps below:

1. First, you should apply the dstributive property:

=(x²-8x+15/3x)(8x/x-3)
=(8x³-64x²+120x)/3x(x-3)

2. As you can see, the common factor in the numerator is: "8x". So, you have:

=8x(x²-8x+15)/3x(x-3)

3. Then, when you simplify, you obtain:

=8(x²-8x+15)/3(x-3)

Therefore, the solution is: 8(x²-8x+15)/3(x-3)

The height of a triangle is increasing at a rate of 2 cm/min while the area of the triangle is increasing at a rate of 12 square cm/min. at what rate is the base of the triangle changing when the height is 4 centimeters and the area is 12 square centimeters?

Answers

Given Information:
- Rate of height = 2 cm/min
- Rate of area = 12 cm^2/min
- Initial height = 4 cm
- Initial area = 12 cm^2
Calculation:
- Find Initial base using initial height and area:
Since A = 1/2 * b * h; Therefore, 12 = 1/2 * b * 4
Solve for b: 12 = 2b; Therefore, b = 6
- Find rate of base:
after 1 minute: height increased 2 cm, area increased 12 cm^2
which is: height = 6, area = 24 <-- (using these, find base)
24 = 1/2 * b * 6; 24 = 3b; b = 8 (after 1 min)
Therefore, since base changed from 6 to 8 the rate is 2 cm/min

Answer: 2 cm/min

Final answer:

When the height of a triangle is 4 cm and the area is 12 square cm, with the height increasing at 2 cm/min and the area increasing at 12 square cm/min, then the base of the triangle is changing at a rate of 5 cm/min.

Explanation:

The subject of this question is Mathematics and is at the High School level. This question deals with the concept of related rates in calculus. First and foremost, remember the formula for the area of a triangle, which is A = 1/2bh, where A is the area, b is the base, and h is the height. Since we're given the rate of change of the height (dh/dt=2 cm/min) and the area (dA/dt=12 square cm/min), we can use this information in combination with the formula for the area of a triangle to derive an implicit function representing the rate of change of the base. By differentiating with respect to time t, we get dA/dt = 1/2b dh/dt + 1/2h db/dt. Plugging in the given values and solving for db/dt (the rate of change of the base length), we get db/dt = (2*dA/dt/h) - dh/dt. Then input the specific values at the given point, h = 4 cm and dA/dt = 12 square cm/min, dh/dt = 2 cm/min. The calculation results in db/dt = 5 cm/min. Therefore, the base of the triangle changes at a rate of 5 cm/min when the height is 4 cm and the area is 12 square cm.

Which ordered pair represents the x-intercept for the linear equation, 3y + 4x = 8?

Answers

3y + 4x = 8 represents a line on the x-y plane, looking like the image I attached.

To find the x-intercept means to find the place where the line intersects the x-axis. If the line is intersecting the x-axis, then the point where it intersects the x-axis must be a place where y = 0. If y didn't equal 0, then that point wouldn't be on the x-axis.

So, to find the x-intercept, we set y in the given equation to 0, like this:
[tex]3y + 4x = 8 [/tex]
[tex]3(0) + 4x = 8[/tex]
[tex]4x = 8[/tex]
[tex]x = \frac{8}{4}[/tex]
[tex]x=2[/tex]
So, [tex]x=2[/tex]. We assumed that [tex]y=0[/tex] to find the x-intercept at the beginning. Then, our ordered pair in the usual order [tex](x,y)[/tex] is [tex](0,2)[/tex]. You can see this is correct by looking at the attached graph.

Final answer:

To find the x-intercept for the equation 3y + 4x = 8, set y to 0 and solve for x, which results in x = 2. Thus, the ordered pair for the x-intercept is (2, 0).

Explanation:

The question is asking to determine the x-intercept of the linear equation 3y + 4x = 8. The x-intercept occurs where the graph of the equation crosses the x-axis, which is when y is equal to 0. To find the x-intercept, you set y to 0 and solve for x:

3(0) + 4x = 8

4x = 8

x = 8/4

x = 2

Therefore, the ordered pair that represents the x-intercept is (2, 0). This is the point on the graph where the line crosses the x-axis.
