Answer:

It will take 6 hours to get to Houston.

Step-by-step explanation:

We have a total distance:

[tex] d_{T} = 746 mi [/tex]      

And, the distance traveled is:

[tex] d = 296 mi [/tex]

The plan is driving at a constant rate of 75 mi/h, so the time to get to Houston is:

[tex]t = \frac{x}{v}[/tex]

Where:

[tex] x = d_{T} - d = 746 mi - 296 mi = 450 mi [/tex]

[tex]t = \frac{x}{v} = \frac{450 mi}{75 mi/h} = 6 h[/tex]

Therefore, it will take 6 hours to get to Houston.

I hope it helps you!

Answer:

When we have a function y = f(x) we define the domain as the set of the values of x, and the range as the set of the values of y.

In this case we have the function:

E(c) where c represents the number of cupcakes sold by the team.

In this case, the domain will be the possible values that c can take.

The restrictions are:

c ≥ 0.

They can not sell a negative number of cupcakes.

c must be an integer because they can not sell a 0.342 of a cupcake, so the domain is discrete.

c may have an upper limit (for example, if they made 500 cupcakes, they can not sell more than 500) But we do not know any upper limit, so we can ignore this restriction.

Then we can define the domain as:

D = {0, 1, 2, 3, ...}

Answer:

8 3/4 below sea level

Step-by-step explanation:

Given that:

Depth of fish at 7:00 A. M = 3 1/2 feets below sea level

Depth at 11:00a.m (4 hours later) = 5 1/4 feets below it's position at 7:00 a. M

Rational number to represent position of fish with respect to the water surface at 11:00 a. M

Position at 11:00 a. M :

Addition of the two depth distances given :

(3 1/2 + 5 1/4)

7/2 + 21/4 = (14 + 21) / 4 = 35 / 4

35/4 = 8 3/4 feets below sea level

Answer:

8.75, 8 3/4 or 35/4

Step-by-step explanation:

3 1/2 + 5 1/4

=(3+5) + (1/2 + 1/4)

=8 + (2/4 + 1/4)

=8 + 3/4= 8 3/4

=8 3/4= 35/4

Answer: For the first part, her total savings would be $88, and for the second part, (let's pretend s = the total savings) the equation would be s = 40 + w x 6.

Step-by-step explanation: As for the first part, we would need to multiply her money per week times the amount of weeks she works. We can do this by simply multiplying the amount she makes (6) by the amount of weeks she works (8), resulting in 48, but we still have to add that number to the amount she already has, or 40, making $88 in total, as for the second part, this does a great job of explaining the reasoning behind that as well.

Answer:

f(x) = -(x+3)(x-4)

f(x) = -[tex]x^{2}[/tex]+x+12

Step-by-step explanation:

The equation of the parabola is y = -(x + 3) (x - 4).

In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.

Given that a graph of a parabola, we need to find the equation of the parabola,

Intercept form equation of the parabola:

y = a(x - p) (x - q), x-intercepts are (-3, 0) and (4, 0).

x = -3 ------ x + 3 = 0

x = 4 ------- x - 4 = 0

y = a(x + 3) (x - 4)

It passes through (0, 12). Substitute (x, y) = (0, 12)

12 = a(0+3)(0-4)

12 = -12a

a = -1

Intercept form equation of the parabola:

y = -(x + 3) (x - 4)

Hence, the equation of the parabola is y = -(x + 3) (x - 4).

Answer:

x = 27

Step-by-step explanation:

The angle at any point on a straight line is 180 degrees.

The middle line over there is creating a right angle which is 90 degrees.

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

Explanation:

Use the slope formula to find the slope of line E

m = (y2-y1)/(x2-x1)

m = (10-8)/(4-7)

m = 2/(-3)

m = -2/3

The slope of line E is -2/3

The slope of line F is also -2/3 since parallel lines have equal slopes but different y intercepts.

[tex]8\leq x[/tex]

Step-by-step explanation:

Given: Moises comes up to Juan and tells him, "I bet you $45 I can get more phone numbers than you!"

Moises gets 8 phone numbers that week

To find: an inequality that represents how many phone numbers Juan needs to not lose the bet.

Solution:

Amount of bet = $45

Number of calls that Moises get that week = 8

Moises wins a bet if he gets more phone numbers than Juan

Let [tex]x[/tex] denotes phone numbers that Juan get.

An inequality that represents how many phone numbers Juan needs to not lose the bet is [tex]8\leq x[/tex]

Henry can download at most 225 MB more.

Step-by-step explanation:

The capacity of Henry's MP3 player is 512MB. He has downloaded 287MB and will continue to download m more megabytes.

Since the capacity of the player is 512MB. The used memory plus 287MB cannot be greater than 512MB, thus the inequality that shows how many more megabytes he can download are:

m + 287 ≤ 512

Solving:

m  ≤ 512 - 287

m  ≤ 225

Henry can download at most 225 MB more.
