Two cars leave New York at the same time traveling in opposite directions. One travels at an average speed of 59mph and the other at 58mph. In how many hours will they be 468 miles apart?
Answer: In 4 HOURS they will be 468 miles apart.
Step-by-step explanation:
1st car DATA:
rate = 59 mph ; time = x hrs. ; distance = 59x miles
2nd car DATA:
rate = 58 mph ; time = x hrs. ; distance = 58x miles
EQUATION:
distance + distance = 385
59x + 58x = 468
117x = 468
x = 4 hours.

Answer:
y=4x-6
Step-by-step explanation:
That is how you would graph it.
Hope this helps!
The first step is to find any two sets of points on the line to find the slope. Let's use (0, -6) and (4,10).
[tex]Slope=\frac{y2-y1}{x2-x1} =\frac{10--6}{4-0} =\frac{16}{4} =4[/tex]
Ok, now we found the slope. Now let's put it into the point-slope form which requires any one point on the line and the slope. Lets use the point (0,-6)
[tex](y-y0)=m(x-x0)\\(y+6)=4(x-0)\\y=4x-6[/tex]
The last equation is the slope-intercept form.

Straight away, we can see there is some sort of reflection over the y-axis.
Eliminate B and D.Then, we can see that, there is a reflection over the x-axis.
Eliminate C.This matches up with A.
Marie built a sand castle that is made a
of two rectangular prisms. If there are
2,000 cubic inches of sand in a bag of
sand, how much sand was left after
Marie built her sand castle? Explain
how you found your answer.
Answer:
Are there any measurements for the size of the prisms? I think we need more info for this. I'll delete this when you answer and upload a new one :)
Step-by-step explanation:
The amount of sand left after building the sand castle is 290 inches³.
What is Rectangular Prism?Rectangular prism is a three dimensional shape which consist of six faces. The two faces are at the top and bottom and the other faces are lateral faces.
We have to find the volume of each of the rectangular prism to know how much sand is used to make the castle.
Volume of a rectangular prism = l × w × h
where l, h and w are length, height and width of the prism respectively.
Volume of larger prism = 15 × 15 × 6
= 1350 inches³
Volume of smaller prism = 9 × 8 × 5
= 360 inches³
Total volume of the castle = 1350 + 360 = 1710 inches³
Remaining sand = 2000 - 1710 = 290 inches³
Hence the sand that remains is 290 inches³.

The length of a rectangle is 6 inches more than the width. If the perimeter is 68 inches, what are the length and the width?
Answer: The length of the rectangle would be 20 inches and the width would be 14 inches.
Step-by-step explanation:
If the length is 20, first, it’s 6 more than 14, and second it would add up to 40. If the width is 14, it’s 6 less than 20, and adds up to 28. If you add those two together, you’d get your total of 68 inches for the perimeter!

The table shows the number of gallons of gas used and the number of miles driven. Gallons of Gas Used 12 15 18 12 14 16 Miles Driven 300 400 450 350 400 450 Is the resulting data set a function? Explain your reasoning. A The table is a function. The function can have more than one input value paired with the same output value. B The table is a function. The function can have more than one output value paired with the same input value. C The table is not a function. The function cannot have different input values paired with the same output value. D The table is not a function. The function cannot have the same input value paired with different output values.
There is one input being mapped into two different outputs, so this is not a function. The correct option is D.
What is a function?A function is a relation that maps elements from one set (the domain) into elements from another set (the range). Such that each element from the domain can be mapped into only one element from the range.
In this case, the table is:
Gallons of Gas Used: 12 15 18 12 14 16Miles Driven: 300 400 450 350 400 450So, the input "12" appears twice, the first time is mapped into 300 miles, and the second time is mapped into 350.
So the same value from the domain is being mapped into two different values of the range, meaning that this is not a function. So the correct option is D.

For problems like this in the future, pay attention to the order of words, and how they go together! For example- "the difference of 23 and a number" means to subtract a number from 23, whereas "the difference of a number and 23" would mean to subtract 23 from the number. Words like "increase" and "sum" both mean addition; "product" and "times" both mean multiplication; "difference" and "less" mean subtraction. Just keep these in mind (and watch for context)!

Problem 3
Answer: Not possible to solveA triangle cannot be constructed with these parameters.
----------------------------
Explanation:
Use the Law of Sines to find angle B
sin(A)/a = sin(B)/b
sin(120)/12 = sin(B)/13
sin(B) = 13*sin(120)/12
sin(B) = 0.93819419
B = arcsin(0.93819419) or B = 180 - arcsin(0.93819419)
B = 69.75047247 or B = 180 - 69.75047247
B = 69.75047247 or B = 110.24952753
These angle values are approximate.
-----------
If B = 69.75047247, then,
A+B+C = 180
C = 180 - (A+B)
C = 180 - (120 + 69.75047247)
C = -9.75047247000001
We get a negative result which isn't valid.
This means B = 69.75047247 isn't valid either.
-----------
If B = 110.24952753, then,
A+B+C = 180
C = 180 - (A+B)
C = 180 - (120 + 110.24952753)
C = -50.24952753
We get a similar conclusion here as well.
-----------
No matter what value of B we go with, we end up with a negative value for angle C.
Negative angles are not allowed.
Therefore, we cannot construct a triangle with sides a = 12, b = 13 and angleA = 120 degrees.
This is one example of an SSA triangle leading to no possible solutions. Refer to the SSA ambiguous case for more info.
-----------
Check out the diagram below. Imagine that point B can be anywhere on the dotted circle. Imagine it can rotate around as in an animation. This circle is centered at point C and has radius a = 12. No matter where point B is placed, we cannot get it to land on the horizontal line to therefore form a triangle. Simply put: side a = 12 is too short.
I used GeoGebra to make the diagram and make sure it's to scale. This is to visually verify that we cannot construct such a triangle with these parameters.
