The question deals with budgeting $60 to buy as many pants and shirts as possible, with at least two pairs of pants to be bought. After purchasing two pairs of pants, the remaining budget can be divided by the price of the remaining item to get the possible quantity.
Explanation:The subject of this question is
Mathematics
, specifically budgeting and maximizing purchases under a fixed budget. You have $60 to spend and each pair of pants costs $8.99, while shirts cost $3.99. If you want to buy at least two pairs of pants, your initial expense will be $8.99 x 2 = $17.98. After buying two pairs of pants, you will have $60 - $17.98 = $42.02 left to spend on either more pants or shirts. Divide this remaining amount by the price of the item you want to buy more of (either pants or shirts) to see how many more items you can purchase. Remember to round the result down to the nearest whole number, since you can't buy a fraction of an item.

Options:
12 hours
15 hours
18 hours
16 hours
Answer:
18 hours
Step-by-step explanation:
We work in fractions of the job done per hour.
So in the case of Tran alone he does 1/9 of the job per hour.
We have the equation 1/9 + 1/x = 1/6 where x is the time taken for Luis to deliver the newspapers.
1/9 + 1/x = 1/6
Multiply through by the LCM 18x:-
2x + 18 = 3x

Jaime has 6 quarters and some dimes in his pocket . The total value of the coins in 4.50. How many dimes does he have in his pockets
Hi there! :)
Answer:
Jaime has 30 dimes in his pocket.
Step-by-step explanation:
First off, you need to know that:
A quarter is equal to = $0.25
A dime is equal to = $0.10
Jaime has 6 quarters, which means that he has 6 times $0.25:
6 × 0.25 = $1.50
Jaime has a total of $4.50 → Subtract the amout of money represented by the quarters and you'll be left with the amout of money represented by the dimes:
4.50 - 1.50 = $3
Jaime has $3 worth of dimes in his pocket. In order to know how many dimes $3 represents, you'll need to divide "3" by 0.10, which is what 1 dime is worth:
3 ÷ 0.10 = 30 → YOUR ANSWER

What is the end behavior of [tex]f(x)=-x^6+2[/tex] ?
Answer:
A. As x→-∞ f(x) →-∞ and as x→∞ f(x) →-∞
Step-by-step explanation:
f(x) = -x^6 +2
As the numbers get very large, the 2 doesn't matter
Let x go to - ∞
f(-∞) = - (- ∞)^6
Anything to an even power is positive
f(-∞) = - ∞
As x →-∞ f(x) →-∞
Let x go to ∞
f(∞) = - ( ∞)^6
Anything to an even power is positive
f(∞) = - ∞
As x →∞ f(x) →-∞

Answer:
continuous.
Step-by-step explanation:
Given function is [tex]f(x)=5x^4-9x^3+x-7[/tex].
and value of a = 7.
Now we need to find if the given function [tex]f(x)=5x^4-9x^3+x-7[/tex] is continuous or not.
By definition of continuity, we know that a function is continuous at a given point if both left and right hand limits are equal.
Left Hand Limit = LHL
[tex]LHL=\lim_{x\rightarrow 7^-}f(x)=5(7)^4-9(7)^3+(7)-7=8918[/tex]
Right Hand Limit = RHL
[tex]RHL=\lim_{x\rightarrow 7^+}f(x)=5(7)^4-9(7)^3+(7)-7=8918[/tex]
Since both limits are equal at a=7 so we can say that given function is continuous at a=7

The total number of restaurant-purchased meals that the average person will eat in a restaurant, in a car, or at home in a year is 189. The total number of these meals eaten in a car or at home exceeds the number eaten in a restaurant by 15. Thirty more restaurant-purchased meals will be eaten in a restaurant than at home. Find the number of restaurant-purchased meals eaten in a restaurant, the number eaten in a car, and the number eaten at home.
Answer:
87 people in the restaurant, 45 people eat in the car and 57 people eat at home.
Step-by-step explanation:
Let x be 'restaurant-purchased meals eaten in a restaurant', y be the 'restaurant-purchased meals eaten in a car' and z be the 'restaurant-purchased meals eaten at home'.
We can use the given information "the total number of restaurant-purchased meals that the average person will eat in a restaurant, in a car, or at home in a year is 189" to write an equation [tex]x+y+z=189[/tex].
We can use the information "the total number of these meals eaten in a car or at home exceeds the number eaten in a restaurant by 15" to write another equation [tex]y+z=x+15[/tex].
We can use the information "thirty more restaurant-purchased meals will be eaten in a restaurant than at home" to write the third equation as x=z+30
Now we need to solve this system of three equations to get the values of x, y and z.
We can solve for x directly from the first two equations.
[tex]x+x+15=189\\2x=174\\x=87[/tex]
Substituting this value of x in the third equation we can get the value of z.
[tex]87=z+30\\z=57[/tex]
Finally, we can substitute the values of x and z in the first (or second) equation to get the value of y.
[tex]87+y+57=189\\y+144=189\\y=45[/tex]
Therefore, 87 people in the restaurant, 45 people eat in the car and 57 people eat at home.
How to solve
3 log 2x=4
Answer:
= 5 * 10 ^ 1/3
Step-by-step explanation:
3 log 2x=4
Divide each side by 3
3/3 log 2x=4/3
log 2x=4/3
Raise each side to the power of 10
10 ^(log 2x)=10 ^(4/3)
2x = 10 ^(4/3)
Divide by 2
2/2x = 1/2 * 10 ^(4/3)
x = 1/2 * 10 ^4/3
10 ^ 4/3 = 10 * 10 ^ 1/3
x = 1/2 ( 10) 10 ^ 1/3
= 5 * 10 ^ 1/3
Mario purchases a prepaid phone plan for $50 at $0.13 per minute. How many minutes can Mario talk on this plan
Mario can talk for 384 minutes on his prepaid phone plan, calculated by dividing his plan's cost, $50, by the per-minute rate of $0.13.
To determine how many minutes Mario can talk on his prepaid phone plan, you would divide the total amount of the plan by the cost per minute. Mario has $50 and the cost per minute is $0.13. To calculate the total minutes, use the formula:
Total Minutes = Total Plan Cost / Cost Per Minute
Let's do the math:
Total Minutes = $50 / $0.13
Total Minutes = 384.6154
Since we cannot have a fraction of a minute in this context, we round down to the nearest whole minute.
Therefore, Mario can talk for 384 minutes on his prepaid plan.

Answer:

lowest degree = 3
maximum of 5 x-intercepts
[tex]y=-4x^7-5x+3[/tex] has y intecept 3
y approaches negative infinity
Step-by-step explanation:
(1) [tex]y=4x^2-3x+7[/tex]
Highest exponent is the degree of the function
Highest exponent =2 so degree =2
Coefficient of x^2 is 4, so leading coefficient is 4
(2) from the graph we can see that
As x approaches infinity, the graph goes down
As x approaches -infinity, the graph goes up
The value of y goes on the opposite direction. So it is a odd degree function. If degree =1 then the graph should be a line
Here the graph is like a curve. Also we have 2 x intercepts . Hence lowest possible degree of the function is 3
(3) y=ax^5+cx^2+f
Here , the degree of the equation is 5
So we will get maximum of 5 x-intercepts
(4) To find the function that has y intercept of 3, we plug in 0 for x in each function
[tex]y=-4x^7-5x+3[/tex]
[tex]y=-4(0)^7-5(0)+3= 3[/tex]
[tex]y=-4x^7-5x+3[/tex] has y intecept 3
(5) [tex]y=-2x^{13}+25x^8-3[/tex]
Here degree is 13 that is odd and leading coefficient is -2 ( negative)
Degree is odd and leading coefficient is negative so the graph of y goes down on the right side.
the graph of y approaches negative infinity when x approaches infinity
The degree and leading coefficient of the polynomial function y=4x2-3x+7 are 2 and 4 respectively. The maximum of x-intercepts for a polynomial graph y=ax5+cx2+f is 5. The polynomial function y=-4x7-5x+3 has a y-intercept of 3 and as x approaches infinity in the function y=-2x13+25x8-3, y approaches negative infinity.
Explanation:1. The degree of the function y=4x2-3x+7 is 2 and the leading coefficient is 4. Therefore B. degree=2 leading coefficient=4 is correct.
2. As the image of the function graphed is not provided, it is impossible to definitively say what the lowest degree of the function is.
3. The maximum number of x-intercepts that can be found on a graph with the equation y=ax5+cx2+f is 5, matching the degree of the polynomial, so D. 5 is correct.
4. The polynomial function y=-4x7-5x+3 has a y-intercept of 3, therefore C. y=-4x7-5x+3 is correct.
5. Since the polynomial y=-2x13+25x8-3 has an odd degree and the leading coefficient is negative, as x approaches infinity, y approaches negative infinity. Therefore D. y approaches negative infinity is correct.

61 = 1/2(y - 119)
Answer:
Option C. [tex]\frac{1}{2}[/tex] ( y-119 ) = 61
Step-by-step explanation:
In the given diagram AB and AC are tangents to circle O.
Length of arc AC = 119°
Inscribed angle between tangents AB and BC is 61°
We have to find the measure 'y' of arc ADC.
As we know the formula

In the Lewis structure for SO2, or sulfur dioxide, there are zero single bonds, two double bonds, zero triple bonds, and one unshared pair of electrons on the central sulfur atom. The correct sequence for SO2 is therefore 0, 2, 0, 1.
Explanation:SO2, or sulfur dioxide, consists of a central sulfur atom with oxygen atoms on both sides. The Lewis structure for SO2 includes one lone electron pair and double bonds with the two oxygen atoms. To calculate this, we first count the valence electrons from the atoms: sulfur has 6 valence electrons and each oxygen atom has 6 as well, for a total of 18 valence electrons.
To start the Lewis structure, we place the least electronegative atom - sulfur - in the center and the two oxygen atoms on each side. We then place a single bond between the sulfur and each oxygen. This accounts for four valence electrons (2 from each bond), leaving us with 14 more. Next, we distribute the remaining electrons to the oxygen atoms as lone pairs, as necessary, to satisfy the octet rule. If there are still electrons left over, we create double bonds until we have used all of the electrons. Here, it results in double bonds between sulfur and each oxygen atom with one lone pair on the sulfur.
Given these steps, for SO2, we have 0 single bonds, 2 double bonds, 0 triple bonds, and 1 unshared pair of electrons on the central atom, sulphur. So the correct option would be 0, 2, 0, 1.

The rectangle below has an area of x^2-11x+30x 2 −11x+30x, start superscript, 2, end superscript, minus, 11, x, plus, 30 square meters and a length of x-5x−5x, minus, 5 meters. what expression represents the width of the rectangle?
Answer:
[tex](x-6)[/tex] meters
Step-by-step explanation:
We have been given that the area of a rectangle is [tex]x^2-11x+30[/tex] square meters and a length of [tex](x-5)[/tex] meters.
Since the area of a rectangle is product of its width and length.
[tex]\text{Area of rectangle}=\text{Width of rectangle*Length of rectangle}[/tex]
We can find width of our rectangle by dividing area of rectangle by length of rectangle.
[tex]\text{Width of rectangle}=\frac{\text{Area of rectangle}}{\text{Length of rectangle}}[/tex]
Let us substitute our given values in above formula.
[tex]\text{Width of rectangle}=\frac{x^2-11x+30}{x-5}[/tex]
Let us factor out numerator by splitting the middle term.
[tex]\text{Width of rectangle}=\frac{x^2-6x-5x+30}{(x-5)}[/tex]
[tex]\text{Width of rectangle}=\frac{x(x-6)-5(x-6)}{(x-5)}[/tex]
[tex]\text{Width of rectangle}=\frac{(x-6)(x-5)}{(x-5)}[/tex]
Upon cancelling out x-5 from numerator and denominator we will get,
[tex]\text{Width of rectangle}=(x-6)[/tex]
Therefore, the expression [tex](x-6)[/tex] meters represents width of the rectangle.

Minimum 22 scarves Jenny has to sell in order to make a profit.
Step-by-step explanation:
Let the number of scarves knitted be 'x'.
Then cost price of the scarves = $ (160+4.5x)
Total selling price of the scarves = $ 12x
In order to attain a profit selling price > cost price
Therefore 12x > 160+4.5x
⇒12x - 4.5x > 160
⇒7.5x > 160
⇒ x >160÷7.5
⇒x > 21.33
SO minimum number of scarves should be 22 a whole number.
To find the minimum number of scarves Jenny must sell to make a profit, set up the inequality 12s > 160 + 4.50s, which represents her earnings from selling scarves being greater than her expenses. Solve for s to obtain s > 21.3. As scarves are sold in whole numbers, Jenny must sell at least 22 scarves to make a profit.
Explanation:To determine the number of scarves that Jenny must sell in order to make a profit, we can set up and solve an inequality. The inequality will represent Jenny's total expenses compared to her total earnings.
Jenny's initial expenses are $160 and it costs $4.50 to make each scarf. This means her total expenses can be represented as 160 + 4.50s, where s is the number of scarves.
Jenny sells each scarf for $12, so her earnings from selling scarves can be represented as 12s.
To establish a profit, Jenny's earnings should be greater than her expenses, so:
12s > 160 + 4.50s
We can solve this inequality by first subtracting 4.50s from each side to isolate the variable:
7.5s > 160
Then, divide both sides by 7.5 to solve for s:
s > 21.3
Since scarves are sold in whole numbers, Jenny needs to sell at least 22 scarves to make a profit.

A line has a slope of -4/5. Which ordered pairs can be points on the line is perpendicular to this line
Answer:
Any ordered pairs which have a slope of 5/4.
Step-by-step explanation:
The line has a slope of -4/5 which means the y values have a difference of -4 and the x values have a difference of 5. If the line is perpendicular to this line then its slope must be the negative reciprocal which is 5/4. Any points which have a difference in y values of 5 and a difference of x values of 4 will be on some line perpendicular to the original.
