For which problem situation could the equation 45x + 55x = 350 be used?
A 350 mile telephone cable costs $55 per mile for one section and $45 per mile for a different section. What is the total cost of the cable?
A car, traveling 45 mph, leaves Dallas heading for Odessa 350 miles away. At the same time, a truck leaves Odessa for Dallas traveling 55 mph on the same road. When will the two vehicles meet?
A 350 mile telephone cable is cut so the shorter piece is 45/55 of the whole cable. How long is each piece?
Two vehicles start from the same point traveling in the same direction. One vehicle travels 55 miles per hour (mph) and the other 45 mph. When will the two vehicles be 350 miles apart?
Answer:
45 x + 55 x = 350
x increases until the total equals 350
45 + 55 = 100 = relative speed of approach
(B) traveling cars meet this equation's specifications (x = 3.5)
The correct statement is option B)
What is the speed of an object?Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time
Given here: The equation as 45x+55x=350
A car, traveling 45 mph, leaves Dallas heading for Odessa 350 miles away. At the same time, a truck leaves Odessa for Dallas traveling 55 mph on the same road.
Therefore the relative speed of the two trucks is given by 45+55=100
and let the time taken to meet is x then we can construct an equation as follows x=350/100
or, 45x+55x=350
Hence, The correct statement is option B)

The Cost C (in dollars) of making n bracelets is represented by C=45n+125. How many bracelets are made when the cost is $845?
So we know the cost is $845, which means this is the cost or our C. Lets input this into our equation and solve.
845 = 45n + 125.
Subtract from both sides:
845-125 = 45n + 125-125
720 = 45n
Divide by 45:
720 / 45 = 45n / 45
16 = n
This means that 16 bracelets can be made if the cost is 845.
We can also re-input the information into the equation to be extra sure!
845 = 45 (16) + 125.
845 = 720 + 125.
845 = 845
Yes!
I hope this helps! :)

Wesley does this work to find the decimal equivalent of 2399. What does his work tell you about the decimal equivalent?
answer is 2399
so yeah mhm yeah u d u m b
Answer:
It is 0.23 with the 23 repeating. The decimal repeats when he divided into the same number twice.
Step-by-step explanation:
23÷99=0.232323232
Since 0.232323232 is a repeating decimal with the 23 repeating, it can be represented as 0.23 with the line over 23
Note:
Sorry for the extra words it doesn't allow me to write the vinculum (the line that indicates a number is repeating)
A rectangular box is designed to have a square base and an open top. The volume is to be 2048in.3
What is the minimum surface area that such a box can have?
Answer:
x=y=z in 3 dimensions. So, you have x2y=4=x3⟹x=y=3√4.
Step-by-step explanation:
Answer:
hi
Step-by-step explanation:
Let x = the length of the sides of the base and h = the height:
Volume = (area of base)(height)
V = x2h
2048 = x2h
2048/x2 = h
Surface Area = area of base + 4(area of vertical side)
SA = x2 + 4xh
Eliminate the h by using 2048/x2 = h:
SA = x2 + 4x(2048/x2)
SA = x2 + 8192 x-1
Take the derivative of SA wrt x, set it to zero, solve for x. Plug that value of x into the surface area equation to find the minimum surface area.

=========================================================
Explanation:
The symbol that looks like an "E" is the uppercase greek letter sigma. It's used for summation. Specifically we are adding terms of the form -4+5n. What we do is replace n with values from the set {2,3,4,...,9,10}. After evaluating each item, we add up the results to get our final answer.
If n = 2, then -4+5n = -4+5*2 = 6 which is the first term.
If n = 3, then -4+5n = -4+5*3 = 11 is the second term
and so on until you reach n = 10.
A table is a handy way to keep track of everything (see below). Adding everything in the second column leads to the final answer of 234.

A parabola with no real zeros, a negative leading coefficient, and an odd y-intercept.
pls help!
Answer:
Step-by-step explanation:
A parabolic graph with no real zeros never touches or crosses the x-axis.
If the leading coefficient is negative, that tells us that the parabola opens down (and, in this case, that the entire graph is below the x-axis, because there are no real zeros.
If the y-intercept is odd, then the constant term, c, in ax^2 + bx + c, must be a negative, odd integer.
Suppose we say that the vertex of a particular parabola that is described by the above is (-2, -1) and that the y-intercept is -3. (Note: this is strictly an example.) Then the vertex equation of this parabola is obtained from the general vertex equation of a parabola,
y = a(x - h)^2 + k. Here h = -2 and k = -1, and so the particular parabola is
y = -a(x + 2)^2 - 1, where a is a constant and -a is negative.
In general form, this would be y = -a(x^2 + 4x + 4) - 1, or
y = -ax^2 - 4ax - 4a -1
and the constant terem (-4a -1) must be an odd negative integer
This is only one of an infinite number of possible equations for the parabola described above.
