A tourist calculated that if he walks to the railroad station with a speed of 4 mph, he’ll miss the train by half an hour, but if he walks with a speed of 5 mph, he’ll reach the station 6 minutes before the departure of the train. What distance does the tourist have to cover?
Answer: 12 miles
Step-by-step explanation:
speed
=
distance
/time
The tourist says that if his speed is 4 mph
, then he will be 30 minutes late (which is 0.5 hours). This means that he will travel d miles in t+0.5 hours.
4=d/t+0.5
The tourist also says that if his speed is 5
mph, then he will be 6 minutes early (which is 0.1 hours). This means that he will travel d miles in t
−
0.1 hours.
5=d/t−0.1
Multiply by the denominator to get 4t+2=d, and 5t-0.5=t.
We know that the two equations are equivalent, so
4t+2=5t-0.5
Simplify
t=2.5
Plug it in to the distance formula
4t+2=d
d=12
The tourist covers 12 miles.

6+3x+-4x=-4 what does x equal
Answer:
x=10
Step-by-step explanation:
sinplify the algebraic terms first, 3x + -4x is equals to -x, so the equation can be rewritten as 6 + -x = -4
now add x to both sides of the equation(which still holds true since you are adding to both sides)
6 = -4 + x
x = 6 + 4 = 10
Answer: x=10
Step-by-step explanation:
3x + -4x= -1x
-6 +-4= -10
-10/-1 is 10
Locate some pieces by these artists, or others who work in the same style, and describe what you see. How does the artist use geometry to elicit a feeling or emotion in the viewer? What might be the artist's purpose in creating the work? In your mind, how does geometry contribute to the success or failure of the piece? Do you appreciate this kind of "geometrical" artwork? Why or why not?
Answer:
Follows are the solution to this question:
Step-by-step explanation:
It is popular for their conceptual paintings or mathematical works, photographers such as Al Held, Bridget Riley, etc. Riley is known through its craft.
Many abstract painting forms are famous in addition to optical art. Its creativity and viewer are imbued with such a sense of creativity. To produce a finished piece which reflects a particular thing, its artistic work combines different colors, structure, or materials.
We like this type of art because it is so, pure types, that allows us to understand the forms of art. These forms examine the relationship between shapes, colors as opposed to traditional forms. In contrast, art reflects culture often. Visual art, hence it's important because it represents a community that has moved after 2000 years.
John and Matt are going to eat at the same restaurant and they are paying separately. Matt ordered 2 burgers and 1 side item, his total was $14.75. John ordered 3 burgers and 2 side items, his total was $24.00.
Write and solve a System of Equations to determine the price of 1 side item.
Answer:
s = 3.75
Step-by-step explanation:
Let b = price of a burger
Let s = price of a side item
2b+s = 14.75
3b+2s = 24
Multiply the first equation by -2
-4b-2s =-29.50
Add to the second equation to eliminate s
-4b-2s =-29.50
3b+2s = 24
---------------------
-b = -5.50
Multiply by -1
b = 5.50
Now find s
2b+s = 14.75
2*5.50 +s =14.75
11 + s = 14.75
Subtract 11 from each side
s = 14.75 -11
s = 3.75

A community pool offers two types of memberships: monthly and yearly. At the beginning of the year the ratio of monthly to yearly was 10:3. However the pool offered an incentive to have members change to the yearly membership. After the incentive the ratio was 5:8. If there were 59 monthly members after the incentive, then there were how many monthly members before the incentive?
Answer:
There were 118 monthly members before the incentive
Step-by-step explanation:
Let the total number of incentive
Monthly membership after incentive = a
Yearly membership after incentive = b
a/b = 5/8
We are told in the question that: 59 monthly members after the incentive,
5/8 = 59/b
Cross Multiply
5b = 59 × 8
b = 59 × 8/5
b = 472/5
b = 94.4
Therefore, number of yearly members = 94.4
Total number of Membership after incentive
= 94.4 + 59
= 153.4
Note that total number of members before incentive = total number of members after incentive
From the question, At the beginning of the year the ratio of monthly to yearly was 10:3.
Monthly membership after incentive = a
Yearly membership after incentive = b
a/b = 10/3
10b = 3a
b = 3a/10
a + b = 153.4
a + 3a/10 = 153.4
10 × a + 3a × 1/ 10 = 153.4
10a + 3a = 10 × 153.4
13a = 1534
Divide both sides by 13
a = 1534/13
a = 118
Therefore, the number of members before monthly incentive = 118

One box can hold 24 muffins and 7 cups of flour are required to make 9 muffins. How many cups of flour are required?
A. 140/3 B. 94 C. 324/5 D. 280 E. 420
Clearly show the work.
Hi!
Your answer would be: 10 cups of flour.
Reason being: You have 8 cups of flour to 24 muffins, which can be shown as 8:24, or 8/24.
You need to find x cups of flour to 30 muffins, which can be shown as x:30, or x/30. You will want to cross multiply.
8 x 24 30
8 x 30 = 24 x X
240 = 24x
10 = x
Therefore, you need 10 cups of flour.
Hope this helps!

Need help with the domain and range
Domain is basically all of x values.
Range is basically all of y values.
That means if you want to find the domain, you can check from the coordinate-x and if you want to find the range, you can check from the coordinate-y.
As you can see in the graph, there are the colored and non-colored dot. Both present the inequality symbol. If it's a colored circle/dot then it's either ≤ or ≥ but if it is non-colored dot then it's either > or <
From the graph, we can say that the minimum value is at -4 when x = -5
and there is no maximum value considering the x = 1 then y = 7 isn't counted due to being uncolored dot.
As mentioned, Domain is the set of all x values. We check the coordinate-x plane and notice that it begins from x = -5 to x = 1. That means it is -5≤x<1
Remember that the x = 1 one is uncolored so it's either > or < but it is < because 1 has more value than -5. Now we know the domain.
About range, we check coordinate-y plane. It starts from -4 to 7. Therefore, the range is -4≤y<7.
Therefore, Domain is -5≤x<1 and Range is -4≤y<7

Find The midpoint of the segment with the given endpoints.
(10,3) and (6,-3)
Answer:
Step-by-step explanation:
You can use the midpoint formula: [tex]\frac{ChangeInX}{2} ,\frac{ChangeInY}{2}[/tex]
So, the Change In X is: 10 - 6= 4
And the Change in Y is: 3 - (-3) = 6
Once you divide both of the changes by 2, you get
X: 2
Y: 3
So the midpoint is: (2,3)
Nicole has $25 to spend on dinner for herself. Tax on her meal is 5.5%, and she wants to tip 20% on the amount of her meal only. Which of the following amounts Nicole could spend on her meal, while still staying under budget after tax and tip are added
Answer:
The meal must cost less than or equal to 19.92
Step-by-step explanation:
Let x be the cost of the mean
First find the tax
tax = x* 5.5%
=.055x
Then find the tip
tip = x * 20%
tip = .20x
Add the total cost together
total cost = meal + tax + tip
=x + .055x + .20x
=1.255x
This must be less than or equal to 25
1.255x ≤ 25
Divide each side by 1.255
1.255x/1.255 ≤ 25/1.255
x ≤ 19.92
Reuben has 26 new magazines to read.
Let M be the number of magazines he would have left to read after reading R of them.
Write an equation relating M to R. Then use this equation to find the number of magazines he would have left to read after reading 21 of them.
Equation:
Nomber left to read after reading 21 of them: magazines
Answer:
5
Step-by-step explanation:
So the total number of magazines he has to read are 26
He has read R magazines = 21 magazines
So the equation relating M to R is
m + r = 26
We also know that r = 21
Hence, m + 21 = 26
subtract 21 from both sides
m = 5
The equation is m + r = 26
And, the number of magazines should be 5
Calculation of the number of magazines:
Since Reuben has 26 new magazines to read
And, here M be the number of magazines he would have left to read after reading R
So here the equation is m + r = 26
Since r = 21
So, m + 21= 26
m = 5

Maylin goes to her local sporting goods store to buy socks and jogging shorts. Socks cost $10 per pair and jogging shorts cost $15 each. At her current consumption bundle pair of 4 pairs of socks and 2 jogging shorts, her marginal benefit from the last pair of socks is 20 and the marginal benefit of the last jogging short is 30. Maylin should ________.
Answer:
Maylin should purchase one unit of each socks & jogging shorts.
Step-by-step explanation:
In case of two goods, consumer is at equilibrium when marginal utility per dollar spent on last unit of the goods are equal, ie MU 1 / P1 = MU 2 / P2 (MU are the marginal utilities / marginal benefit of two goods, P are the price of two goods)
Given : MU1 (So) = 20, MU2 (JSh) = 30, P1 (So) = 10, P2 (JSh) = 15
So, equilibrium is at where MU1 (So) / P1 (So) = MU2 (JSh) / P2 (Jsh)
20/10 = 2, & 30/15 = 2. MU's per dollar are equal for both.
So Maylin is in equilibrium, she should purchase one unit of each socks & jogging shorts.
The consumption schedule for Maylin is given as
4 pairs of socks at $10 per pair
2 jogging shorts at $15 per short
Marginal benefit from socks = MUs = 20
Marginal benefit from socks = MUj = 30
To maximize utility. The necessary condition =
[tex]\frac{MUs}{Ps} =\frac{MUj}{Pj} \\\\\frac{20}{10} =\frac{30}{15}[/tex]
2 = 2
The condition is fulfilled because the utility maximization is met.
Therefore Maylin should leave her consumption bundle unchanged.
