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.

Bob works at a café, where he earns $11 an hour. Which of the following graphs describes the amount of money that Bob earns after x hours?
Question 15 options:
A Cartesian plane with x-axis labeled "Time (hr)" and y-axis labeled "Earnings ($)". The line intersects the y-axis at y=0, and increases by $11 for every 1 hour.
A Cartesian plane with x-axis labeled "Time (hr)" and y-axis labeled "Earnings ($)". The line intersects the y-axis at y=11, and increases by $0.50 for every 1 hour.
A Cartesian plane with x-axis labeled "Time (hr)" and y-axis labeled "Earnings ($)". The line intersects the y-axis at y=11, and increases by $11 for every 1 hour.
A Cartesian plane with x-axis labeled "Time (hr)" and y-axis labeled "Earnings ($)". The line intersects the y-axis at y=0, and increases by $10 for every 1 hour.
Answer:
First one
Step-by-step explanation:
When he works 0 hr then he will make $0. So the line will intersect y axis at y= 0
He makes $11 an hr. So the earning increases by 11 for every 1 hr
here a subtraction problem that has been solved incorrectly for 21-9=11 choose the addition sentence that check this subtraction problem the choices are 21-9=11 29+9=30 what is the correct answer but my answer came to 21+9=30 all it said is change it to a addition problem
Answer:
11+ 9 = 20
Step-by-step explanation:
=> 21-9=11
21 - 9 equals to 11 is actually a wrong answer
So in order to find the subtraction problem that will help us truly know whether the equation is wrong
=> 11+ 9 = 20
OR THE SECOND EQUATION IS
=> 21 - 11 = 10

Answer:
Base 10 is always the decimal system which is from (0-9).
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!
Choose the symbol that correctly compares these numbers.

Answer:
1) In fig. (1) there are 2 shapes:
A Rectangle A triangleSo,
Area of Rectangle = l × b
where,
length (l) = 12 cm breadth (b) = 14 cm➮ 12 × 14
➮ 168
Hence, the area of rectangle is 168cm².
Now,
Area of Triangle = ½bh
where,
base (b) = 8 cm height (h) = 12 cm➮ ½ × 8 × 12
➮ ½ × 96
➮ 48
Hence, the area of triangle is 48cm².
Thus, Area of the whole fig. :
Area of Rectangle + Area of Triangle
➮ 168 + 48
➮ 216cm² (Ans)
2) In fig. (2) there are also 2 shapes :
A SemicircleA RectangleSo,
Area of Semicircle = ½ (πr²)
where,
pi (π) = 3.14 radius (r) = 5 inches➮ ½ × 3.14 × (5)²
➮ ½ × 3.14 × 25
➮ ½ × 78.5
➮ 39.25
Hence, the area of semicircle is 39.25 in².
Now,
Area of Rectangle = l × b
where,
length (l) = 10 inchesbreadth (b) = 15 inches➮ 10 × 15
➮ 150
Hence, the area of rectangle is 150 in².
Thus, Area of whole fig. :
Area of Semicircle + Area of Rectangle
➮ 39.25 + 150
➮ 189.25 in² (Ans)

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.

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.

If x2 + y2 + z2 = 9, dx dt = 3, and dy dt = 9, find dz dt?
Answer:
dz/dt = -(3x + 9y)/z
Step-by-step explanation:
x² + y² + z² = 9
2x dx/dt + 2y dy/dt + 2z dz/dt = 0
x dx/dt + y dy/dt + z dz/dt = 0
x * 3 + y * 9 + z dz/dt = 0
so
dz/dt = -(3x + 9y)/z

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.
