Answer:

A- Rational

Step-by-step explanation:

If a and b are rational and b is not zero, then a/b is also rational. Indeed, if a=m/n and b=p/q, where m,n,p, and q are integers, then a/b=mq/pn, i.e. it is also a ratio of two integers, and is therefore rational.

The coordinate grid shows points A through K. What point is a solution to the system of inequalities?

Eddi Din [679]

Answer:

Option D) F

Step-by-step explanation:

we have

$y < -2x+10$ -----> inequality A

The solution of the inequality A is the shaded area below the dashed line $y=-2x+10$

The y-intercept of the dashed line is (0,10)

The x-intercept of the dashed line is (5,0)

$y < \frac{1}{2}x-2$ ----> inequality B

The solution of the inequality B is the shaded area below the dashed line $y=\frac{1}{2}x-2$

The y-intercept of the dashed line is (0,-2)

The x-intercept of the dashed line is (4,0)

The solution of the system of inequalities is the shaded area between the two dashed lines

see that attached figure

Remember that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area of the solution

therefore

The solution are the points

E, F and G

Find the surface area of a cylinder with a base diameter of 8ft and a height of 6ft. Write your answer in terms of pi, and be su

Ksju [112]

Given that diameter of the base of the cylinder = 8 ft

Given that height of the cylinder = 6 ft

We have to find the surface area of the cylinder in terms of pi.

So we need to use formula of surface area of the cylinder which is

$Area= 2\pi r(r+h)$

where h= height = 6

r= radius = diameter/2 = 8/2 = 4

Now plug these values into above formula

$Area= 2\pi *4(4+3)$

$Area= 2\pi *4(7)$

$Area= 2\pi *28$

$Area= 56\pi$

Hence final answer is

$Area= 56\pi$ square ft
