$(3,\ 4)\to x=3,\ y=4\\\\y > x+2$

Substitute the values of x and y to the inequality:

$4 > 3+2\\\\4>5\ \ FALSE$

<h3>Answer: (3, 4) is not a solution if given inequality.</h3>

Sam has 1000 to distributed among two groups equally. Later ,the first part is divided among five children and second part is di

melisa1 [442]

So basically sam split the 1000 to 2 groups so we have 1000 ÷ 2
now the first group divided the 500 (since 1000÷ 2 is 500) among five children so it would be 500 ÷ 5 which equals 100 per child and the second group divided their 500 between to boys, so you would get 500÷2 which is 250
so for group one it would be: 1000÷2÷5 which equals 100 per child and the second group is 1000÷2÷2 which equals 250 for each brother

Im not so sure about this. I need help making a proof that is 9 steps long. (See image)

Leona [35]

Step-by-step explanation:

Not entirely sure, but I believe something like this:

∠1 + ∠2 = 180° since they are a linear pair;

Since ∠1 = ∠2, we can say:

∠1 + ∠1 = 180°

2(∠1) = 180°

∠1 = 90°

And since:

∠1 = ∠2

∠2 = 90°

So the angle between t and s is 90°;

An angle of 90° means t and s are perpendicular (⊥)

A spherical ball just fits inside a cylindrical can,16 centimeters y'all, with a diameter of 16 centimeters. What is the express

Veseljchak [2.6K]

Answer:

The correct answer is the expression of the volume of the sphere is $\frac{4}{3}$ ×π× $8^{3}$ and the expression of the volume of the leftover space is π× $8^{3}$ ×16 - $\frac{4}{3}$ ×π× $8^{3}$ .

Step-by-step explanation:

Height of the given cylindrical can = 16 cms.

Diameter of the given cylindrical can = 16 cms.

Now a spherical ball just fits in this given cylindrical can. Thus the diameter of the ball is equal to the diameter of the can, equal to 16 cms.

Thus the expression of the volume of ball = $\frac{4}{3}$ ×π× $r^{3}$ = $\frac{4}{3}$ ×π× $8^{3}$

Expression of the volume of the cylindrical can is π× $r^{3}$ × h = π× $8^{3}$ ×16

Expression of the leftover volume would be volume of can minus volume of the ball = π× $8^{3}$ ×16 - $\frac{4}{3}$ ×π× $8^{3}$ .
