If rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated, how many hours must have passed if there are 5 inches of rain? Create a linear equation that is a model for the rain that has accumulated. Select the two correct answers. (1 point)
Given :
Rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated.
To Find :
How many hours must have passed if there are 5 inches of rain .
Solution :
Let , after x hours rain accumulated is 5 inches .
We know , general equation of line :
y = mx +c
Here , m = 0.5 and c = 1 .
So , equation of rain accumulated is :
[tex]y=0.5x+1[/tex]
Now , putting value of x = 5 hours .
We get :
[tex]y=0.5\times 5+1\\\\y=2.5+1=3.5\ inches[/tex]
Hence , this is the required solution .
Answer:
0.5h+1.5=5
1.5h+0.5=5

is 2.7 a rational or a irrational
Answer:
Rational
Step-by-step explanation:
2.7 can be written as a fraction, so therefore it is ration[tex]2.7=2\frac{7}{10} =\frac{27}{10}[/tex]al.
The number 2.7 is a rational number.
A rational number is a number that can be expressed as a ratio of two integers, where the denominator is not zero.
In other words, a rational number can be written in the form p/q, where p and q are integers, and q is not equal to zero.
Now, let's express 2.7 as a fraction:
2.7 = 27/10
Since 27 and 10 are both integers, and the denominator (10) is not zero, we have successfully expressed 2.7 as a fraction of two integers.
Therefore, 2.7 is a rational number.
On the other hand, an irrational number cannot be expressed as a simple fraction of two integers. Examples of irrational numbers include π (pi) and √2 (the square root of 2).
These numbers have non-repeating and non-terminating decimal expansions, and they cannot be written as a fraction of two integers.
However, 2.7 is a terminating decimal (it has a finite number of decimal places), and it can be expressed as a fraction, making it a rational number.

As we look at both triangles, we can see that they have a few things in common.
Each triangle shares a right angle, one leg, and an acute angle.
LL = leg and leg
HA = hypotenuse and angle
HL = hypotenuse and leg
LA = leg and angle
The triangles do not share two legs, nor do they share a hypotenuse.
Therefore,
LA is the only choice that makes sense.
For these two right triangle, LA(Leg and angle) verifies that ΔDEF ≅ ΔSTU.
What is the condition of congruence of two right triangles?If the hypotenuse and a side of a right- angled triangle is equivalent to the hypotenuse and a side of the second right- angled triangle, then the two right triangles are said to be congruent.
In these two given right triangles, ∠D = ∠S and ∠F = ∠U.
Therefore, the third angle of each triangle are equal as per the third angle theorem.
The leg of each triangle is equal as mentioned.
Therefore, LA(Leg and angle) verifies that ΔDEF ≅ ΔSTU.

if a car travels 45 miles in 30 minutes how far will the car travel in 2.5 hours
Answer:
225
Step-by-step explanation:
well divide 45 by 30 to get miles per min. = 1.5
and theirs 150 min in 2 1/2 hours
so now multiply 150 by 1.5 = 225

4. Explain how to graph the equation y = -2x + 3 *
Answer:
Step-by-step explanation:
Easy way: type the equation into a graphing calculator.
__
By hand: find a couple of points and draw a line through them.
The equation is in "slope-intercept" form:
y = mx + b
where m is the slope (-2) and b is the y-intercept (3). The y-intercept is where the line crosses the y-axis, so right away you know one point on the line. That point is (0, 3).
The slope of -2 means for each horizontal unit, the line drops 2 units vertically. The point 1 unit to the right of (0, 3) is (1, 3); and the point 2 units below that is (1, 3-2) = (1, 1). So, another point on the line is (1, 1).
You can plot those two points and draw the line through them.
