8.) Henry's MP3 player has 512MB of memory.
He has already downloaded 287MB and will
continue to download m more megabytes.
Write and solve an inequality that shows how
many more megabytes he can download.
Answer:
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.

−2.5⋅0.6⋅5.8=−2.5⋅5.8⋅0.6
i dont know ethrreer
Step-by-step explanation:
Answer:
Step-by-step explanation:The distributive property dictates that:
a(b + c) = ab + ac
Thus,
(0.7 x 0.7) + (0.7 x 0.9) + (0.7 x 0.2)
= 0.7(0.7 + 0.9 + 0.2)
follows the distributive property. The third option is correct.

−23
Answer:
y = 4/9
Step-by-step explanation:
2(−2x+1)−5x+2 = 0
2*(−2x) +2*(1)−5x+2 = 0
-4x +2 -5x +2 = 0
-9y +4 = 0
-9y = -4

A fish was swimming 3 in a half feet below the water surface at 7:00 a.M. Four hours later, the fish as at a depth that is 5 one fourth feet below where it was at 7:00 a.M. What rational number represents the position of the fish with respectto water surface at 11:00 a.M
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

Solve for x.
a) 30
b) 27
c) 33
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.
This must mean that both sides are 90 degrees.
3x+9 = 90
3x = 81
x = 27

Write a function in any form that would match the graph shown below.
Answer:

f(x) = -[tex]x^{2}[/tex]+x+12
Step-by-step explanation:
The equation of the parabola is y = -(x + 3) (x - 4).
What is parabola?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).

Line e passes through points (7, 8) and (4, 10) Line f is parallel to line e. What is the slope of line f?
==================================================
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.
The distance from El Paso Texas to Houston
Texas is approximately 746 miles. If you
have already traveled 296 miles and you plan
on driving at a constant rate of 75 miles per
hour, how long will it take to get to Houston?
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: 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. Hope this answered your question!
Moises comes up to Juan and tells him, "I bet you $45 I can get more phone numbers than you!". Juan takes Moises up on that bet. If Moises gets 8 phone numbers that week, write an inequality that represents how many phone numbers Juan needs to not lose the bet.
Answer:
[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]
