A teacher wants to test the effectiveness of two
different math textbooks. She divides her class
into two groups. One group studies out of
textbook A and the other out of textbook B. At
the end of the year she tests both groups to
see which one scores higher. This is an
example of

Answer:

Answer:

4.375cm

Step-by-step explanation:

You have to look at what volume equals Volume= l×w×h so 3/2 × 5/4 × 7/3

Step-by-step explanation:

18x²-8

= 2(9x²-4)

= 2(3x+2)(3x-2)

18x² - 8

Common factor is 2.

=》18x² - 8

=》2 (9x²- 4) [option C].

Answer:

26 degrees Celcius

Step-by-step explanation:

The minimum temperature is -11

The maximum temperature is 15

to get from -11 to 0: add 11

to get from 0 to 15: add 15

11+15 = 26

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:

given 4bags of cement =18m2

1 bags of cement =18/4=4.5m2

7 bags of cement =7*4.5=31.5m2

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:

The answer is 256.34mm^2

Step-by-step explanation:

Radius = 9mm

Area = πr^2

Area = 3.14×(9)^2

Area = 3.14×81

Area = 256.34mm^2

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

Answer:

1/2 is a rational number.

Step-by-step explanation:

A rational number can be expressed as a ratio of two numbers. 1/2 is a ratio.

It is also a real number, however you do not list that as a category, so from what you listed, it is only a rational number.

Answer:

Step-by-step explanation:

-3x - 45 + 4 - 5x = 10x - 5

-8x - 41 = 10x - 5

-18x = 36

x= -2

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]

3(3a²-2x)

Step-by-step explanation:

that right answer

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:

its 16

Step-by-step explanation:

area for a triangle is 1/2 the base times the height.

IN order to find out the base you need to multiply the area by two and then divide by 42 to find the base. X will represent the base

so

336 *2 = 42x

672= 42x

672/42=x

16 = x

Well visualize a 10 foot ladder leaning on a wall and how the space from the distance of the wall are gonna form an angle in this question it tells you it forms a 30 degree angle so your gonna go up 10 feet and out how much the angle is on a slant and multiply the two numbers?

the space between is what your determining.

     /l

   /  l < that is the wall

 /    l

/      l

^that is the ladder
