Someone pls help me and I will give brainliest of you answer correctly. plssssss

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)

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)

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.

option C is correct answer

Answer:

50

Step-by-step explanation:

From the pattern, you can see that to get y from x, you have to multiply 5.

For example:

[tex]1*5=5[/tex]

[tex]4*5=20[/tex]

[tex]6*5=30[/tex]

Thus,

[tex]10*5=50[/tex]

Answer:

60

Step-by-step explanation:

Sorry if it was wrong ight so what i did was 6 divied by 10 and got 0.6 i know u can't put 0.6 so i multiplied 6 by 10 and got 60

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!

240

Step-by-step explanation:

it’s simple math!

Since 60% of the 400 kids want more Library books, all you need to do is:

100% - 60% = 40%

find 40% of 400:

400 x 0.4 = 160

then subtract 160 from 400 to get 60%:

400 - 160 = 240

therefore 240 is your answer! :)

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.

Answer:

The Answer is A

Step-by-step explanation:

First you take 3/8 and 3/5. After that, you put 3/8 over 3/5. To get Miles per Hour, you want to put distance over time. Next you invert and multiply. When you are doing this you want to have it looking like this: [tex]\frac{3}{8}[/tex] * [tex]\frac{5}{3}[/tex]. Finally you multiply the top and the bottom and reduce the fraction. Your final answer will me 5/8.

Answer:

n=-7.75

Step-by-step explanation:

Based on the given conditions, formulate: 5.5+2×X=-10

Rearrange unknown terms to the left side of the equation:2x=-10-5.5

Calculate the sum or difference:2x=-15.5

Divide both sides of the equation by the coefficient of variable:x=-15.5/2

Multiply both the numerator and denominator with the same integer:-155/20

Cross out the common factor:-31/4

get the result:  -7.75

Answer: -7.75

=========================================================

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.
