Answer:

[tex]x < 0[/tex]

Step-by-step explanation:

Given

The expression is:

[tex]-3x > 0[/tex]

Required

Determine the inequality

[tex]-3x > 0[/tex]

Divide both sides by -3

[tex]\frac{-3x}{-3} > \frac{0}{-3}[/tex]

The inequality sign changes after the division because we're dividing be a negative number (-3).

So, we have:

[tex]x < 0[/tex]

Hence, the inequality is: [tex]x < 0[/tex]

Answer:

56 inches cubed

Step-by-step explanation:

First divide into two boxes.

One of them being 1 in by 2 in by 4 in

The second one being 3in by 4 in by 4in

1 X 2 X 4 = 8

3 X 4 X 4 = 48

8+48= 56 in cubed

Step-by-step explanation:

Volume of Sphere

= 4/3πr³

= (4/3)(3.14)(60/2)³

= 113,040ft³.

The diameter of the sphere is 60 ft

Volume of sphere = 4/3πr³

= (4/3)(3.14)(60/2)³

= 113,040ft³

The volume of the given sphere is 113,040ft³

Answer:

5) First you have to find x, then use it with supplementary angles theorem.

6) STQ = 150˚

Step-by-step explanation:

To find x, add (2x+8), (71-x), and 90˚ together to add up to 180˚ (those three angles are supplementary):

(2x+8) + (71-x) + 90 = 180˚

x + 169 = 180

Then solve for x:

x = 11

You can check if x is right by inputing it back into the two equations and see if all three of the angle measures together equal 180˚.

Now, you only need m∠MTS (2x+8) to find m∠STQ...

m∠MTS + m∠STQ = 180˚ because they are supplementary angles.

Input the found x to find m∠MTS:

(2(11)+8) = 30

Subtract 30 from 180 to find m∠STQ:

180 - 30 = 150

m∠STQ = 150˚

Answer:

Let's define:

P = pies that Phoebe ate

F = pies that Finn ate

We know that together they ate 29/12 pies, then:

P + F = 29/12

We know that Finn ate more than Phoebe, then F > P.

And we know that Phoebe ate more than 5/6 of a pie, then:

P > 5/6.

Then we have the relations:

P + F = 29/12

P > 5/6

F > P

To find different combinations we can just give one of the variables a value.

We have a direct condition on P, which is:

P > 5/6

So we can just give P any value larger than 5/6 and find the value of F.

For example:

P = 6/6 = 1

Then:

F + 1 = 29/12

F = 29/12 - 1 = 29/12 - 12/12 = 17/12

And 17/12 > 5/6

So we meet the condition F > P.

Then we have the combination:

P = 1

F = 17/12

Now let's find another condition, this time let's use:

P = 5/6 + 1/12 = 10/12 + 1/12 = 11/12

Then:

F + 11/12 = 29/12

F = 29/12 - 11/12 = 18/12

And 18/12 > 11/12

Then we meet the condition:

F > P.

We have the combination:

F = 18/12

P = 11/12

Now for the last combination, we can use:

P = 5/6 + 3/12 = 10/12 + 3/12 = 13/12

Then:

F + 13/12 = 29/12

F = 29/12 - 13/12

F = 16/12

And 16/12 > 13/12

Then we meet the condition F > P

We have the combination:

F = 16/12

P = 13/12.

Answer:

9/35.............,..........

Answer:

1/5

Step-by-step explanation:

2/5 - 1/7 = ???

find the least common denominator!

45 would be the least common demoninator!

so...

2 (7) / 5(7) - 1 (5) / 7 (5) = ?

14/ 45 - 5 /45 = ?

14 - 5 = 9

9/45. Simplify!

9/45 divide 9 from both sides

9/9 /  45/9

= 1/5, one fifths is your answer!

Is there any other question that you have??? (preferably one that could be answered)
