2/3 x 5/6 = 5/9
3/2 x 6/5 = 9/5

It’s basically the numerator and denominator flipped

Answer:

Area = 6.25 $\pi$ ft^2

Step-by-step explanation:

Area = $\pi \\$ $r^{2}$

The diameter is 5 feet. That makes the radius 2.5 feet

Area = $\pi \\$ $r^{2}$

Area = $\pi \\$ $2.5^{2}$

Area = 6.25 $\pi$ ft^2

Hey there! posted picture of question help please

Firdavs [7]

1. To answer the questions shown in the figure atttached, it is important to remember that the irrational number e is aldo called "Euler's number" and you can find it in many exercises in mathematics.

2. Then, the irrational number e is:

e=2.71828

3. When you rounded, you have:

e=2.718

4. Therefore, as you can see, the the correct answer for the exercise above is the option c, which is: c. 2.718

Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 2x-y=

Bond [772]

Answer:

The system of linear equations has infinitely many solutions

Step-by-step explanation:

Let's modified the equations and find the answer.

Using the first equation:

$2x-y=5$ we can multiply by 2 in both sides, obtaining:

$2*(2x-y)=2*5$ which can by simplified as:

$4x-2y=10$ which is equal to:

$4x=2y+10$

Considering the second equation:

$=4x+ky=2$

Taking into account that from the first equation we know that: $4x=2y+10$ , we can express the second equation as:

$2y+10+ky=2$ , which can be simplified as:

$(2+k)y=2-10$

$(2+k)y=-8$

$y=-8/(2+k)$

Because (-8) is being divided by (2+k), then (2+k) can't be equal to 0, so:

$2+k=0$ if $k=-2$

This means that k can be any number different than -2, and for each of these solutions, there is a different solution for y, allowing also, different solutions for x.

For example, if k=0 then

$y=-8/(2+0)$ which give us y=-4, and, because:
