jerry is a judge. He hears 5 cases every 2 3/8 hours. Jerry hears caese at a constant rat. How many cases does he hear per hour

faust18 [17]

Answer:

The number of cases heard by Jerry per hour is $2\frac{21}{500}$

Step-by-step explanation:

The rate of hearing the cases is 5 cases in 2 3/8 hours.

Now, $2\frac{3}{8} = 2+\frac{3}{8} = 2 + 0.375 = 2.375$

⇒The judge hears 5 cases in 2.375 hours.

So, the number of cases per hour = $= \frac{\textrm{Total Number of cases heard}}{\textrm{Number of Hours}} = \frac{5}{2.375}$

= 2.105

Also, $2.105 = 2 + 0.105 = 2 + \frac{105}{1000} = 2+\frac{21}{500} = 2\frac{21}{500}$

Hence, the number of cases heard by Jerry per hour is $2\frac{21}{500}$

If (x,y) is a solution to the system of equations shown below, what is the product of the y-coordinates of the solutions? x^2+4y

aliina [53]

Answer:

The product of the y-coordinates of the solutions is equal to 3

Step-by-step explanation:

we have

$x^{2}+4y^{2}=40$ -----> equation A

$x+2y=8$ ------> equation B

Solve by graphing

Remember that the solutions of the system of equations are the intersection point both graphs

using a graphing tool

The solutions are the points (2,3) and (6,1)

see the attached figure

The y-coordinates of the solutions are 3 and 1

therefore

The product of the y-coordinates of the solutions is equal to

(3)(1)=3

What function is the inverse of the exponential function y = (1.5)x?

vagabundo [1.1K]

Correct question is;

What function is the inverse of the exponential function y = 1.5^(x)?

Answer:

y = log_1.5_x

Step-by-step explanation:

The inverse of exponential functions is usually written in form of logarithm.

For example inverse of y = p^(x) will be written as; y = log_p_(x)

Similarly applying this same pattern to our exponential function y = 1.5^(x), we have the inverse as;

y = log_1.5_x

2. Which equation is equivalent to 2 + 4x = 5 - 3(x + 1)? A. 2 + 4x = 2x - 3 B. 2 + 4% = 5 - 3 -3. C. 6x = 5-(+ 1). D. 2 + 4 = 2

Andre45 [30]

Answer:

B) 2 + 4x = 5 - 3 - 3x

Step-by-step explanation:

By simplifying JUST the right side and re-arranging them

2 + 4x = 5 - 3(x + 1),

2 + 4x = 5 - 3x -3,

2 + 4x = 5 -3 - 3x
