The Lopez family is traveling from the beach to their house at a average speed of 65 miles per hour. At noon, they have driven 50 miles. Which equation represents the total distance they have driven, d, in terms of the number of hours since noon, h?
The equation that represents the total distance they have driven, d, in terms of the number of hours since noon, h is:
d = 65h + 50
Which equation represents the total distance that the family has traveled?The equation that represents the total distance that the family traveled must show the initial distance they started with, the velocity at which they are traveling and the time they have covered.
The initial distance that they started with is = 50 miles
The velocity at which they are traveling is 65miles/hr
Therefore the total distance they have driven, d, in terms of the number of hours since noon, h
= 65h + 50
Therefore, the third option is correct.

How can you determine the equation of a line in y =mx + b form from its graph?
Answer:
I'm gonna go a little out of order.
To determine b, find where the line crosses the y-axis. If it's positive, put it as " + " and if it's negative, put it as " - ".
To determine m, find two points on the line that are directly on the number. Example, choose (4, 1) instead of (4.1, 5.2). Go up/down and left/right (while making sure to count) until you reach the second number. going up and right will be considered positive while down and left are considered negative.
Using rise/run, put your number for up/down as a numerator over your left/right, which will be a denominator.
Insert m and b and you're good to go!

Explain how the net of rectangular prism can help you find the surface area or the prism?
A 3d cardboard box has 6 sides, each of which are rectangles. If you unfold the 3D box, and flatten it out, then you'll be left with 6 rectangles such as what you see in the attachment below. This is one way to unfold the box. This flattened drawing is the net of the 3D rectangular prism. You can think of it as wrapping paper that covers the exterior of the box. There are no gaps or overlapping portions. If you can find the area of each piece of the net, and add up those pieces, that gets you the total area of the net. This is the exactly the surface area of the box.
In the drawing below, I've marked the sides as: top, bottom, left, right, front, back. This way you can see how the 3D box unfolds and how the sides correspond to one another. Other net configurations are possible.

Evan borrowed money from his mom. If he paid her back 9.60 which is 20% of the total he owns, then how much did he owe her to begin with
Given:
Evan paid his mom back 9.60 which is 20% of the total he owns.
To find:
How much did he owe her to begin with.
Solution:
Let x be the amount Evan owns.
According to the question,
20% of x = 9.60
[tex]\dfrac{20}{100}x=9.60[/tex]
[tex]\dfrac{1}{5}x=9.60[/tex]
Multiply both sides by 5.
[tex]x=48[/tex]
Therefore, Evan owns 48 from his mom.
d is proportional to S^2
d=900 when s=20
calculate the value of D when S=25
Answer:
d = 1406.25
Step-by-step explanation:
Given d is proportional to s² then the equation relating them is
d = ks² ← k is the constant of proportion
To find k use the condition d = 900 when s = 20
900 = k × 20² = 400k ( divide both sides by 400 )
2.25 = k
d = 2.25s² ← equation of proportion
When s = 25, then
d = 2.25 × 25² = 2.25 × 625 = 1406.25
The first term of an arithmetic sequence is 12. The 9th term is -20. What is the common
difference of the arithmetic sequence?
Answer:
-4
Step-by-step explanation:
The formula of an arithmetic sequence is nth term=a+(n-1)d. First term is a and common difference is d.
Let's plug our info in.
-20=12+(9-1)d
-20=12+8d
Subtract 12 from both sides.
-32=8d
Divide both sides by 8.
d=-4

How do i get the answer x= 3, -1 for equation (3/x^2)+ 2/x =1
Answer:
Steps below
Step-by-step explanation:
(3/x²)+ 2/x =1 (x ≠ 0)
(3/x²) + 2x/x² = 1
(3 + 2x) / x² = 1
3 + 2x = x²
x² - 2x - 3 = 0
(x + 1) (x - 3) =0
x = -1 or x = 3

The energy that generates wind comes from what source A. Soar radiation B. Magnetic attraction C. Moon's gravity D. Coriolis effect
Answer:
A. Soar radiation
Step-by-step explanation:
Blowing wind rotates the wind turbine and generates the energy called wind energy. More the speed of wind, more the energy can be generated.
That's how, wind energy depends on the speed of the wind and the speed of the wind is due to the pressure difference in various regions.
The zone having more solar radiation has low pressure and the zone having less solar radiation have high pressure of air and winds flows from high to low-pressure zone.
Therefore, the energy that generates wind comes from what source soar radiation.
Hence, option (A) is correct.

====================================================
Explanation:
The Pythagorean theorem converse can be used to determine if we have a right triangle or not.
The converse says that if a^2 + b^2 = c^2 is a true equation, then we have a right triangle.
The value of c is always the longest side. The order of 'a' and b doesn't matter (usually b is larger than or equal to 'a'). So we could have [tex]a \le b < c[/tex] or [tex]b \le a < c[/tex], but convention usually leans toward the first inequality mentioned.
----------------------------------
In choice A, we have the following steps
a^2 + b^2 = c^2
(7.5)^2 + (18)^2 = (21.5)^2
380.25 = 462.25
Since the third equation is false, this means the first equation is false for those a,b,c values. Choice A is not a right triangle. We can cross it off the list.
----------------------------------
In choice B, we have a = 7.5, b = 19.5 and c = 21.5
So,
a^2 + b^2 = c^2
(7.5)^2 + (19.5)^2 = (21.5)^2
436.5 = 462.25
which is also false. Cross choice B off the list.
-----------------------------------
With choice C we have: a = 18, b = 19.5, c = 21.5
a^2 + b^2 = c^2
(18)^2 + (19.5)^2 = (21.5)^2
704.25 = 462.25
Cross choice C off the list since the third equation is false.
-------------------------------------
In choice D, we have the sides a = 7.5, b = 18, c = 19.5
a^2 + b^2 = c^2
(7.5)^2 + (18)^2 = (19.5)^2
380.25 = 380.25
We get the same number on both sides, so the third equation is true. Consequently, this leads to the first equation being true for those a,b,c values. Choice D is a right triangle, and it's the final answer.

Step-by-step explanation:
Explain why it makes sense that a system of two lines with equal slopes but different y-intercepts has no solutions.
Answer:
Please check explanations
Step-by-step explanation:
Here, we want to seek why the system has no solutions
An example is necessary
Let us have two lines with equal slopes and different y-intercepts
y = 2x + 5
y = 2x - 3
To solve this system, we equate the y-values
2x + 5 = 2x - 3
The reason why this has no solution is that there is no x value that would validate the equality
It is impossible to find an x value which when inserted would make both equations equal
In the absence of this, we can make that conclusion that the system of equations has no solution
