Clare has a set of cubes with a volume of 1 cm³ each. She also has a box with a volume of 24 cm³. Exactly two layers of cubes can fit in this box. How many cubes must be in each layer? its a school problem I'm having trouble with

Answers

Answer:

12 cubes

Step-by-step explanation:

If the total volume of the box is 24 cm³ and the volume of each cube is 1 cm³ then that means that 24 total cubes can fit perfectly inside the box. Since there can only be two layers of cubes then we simply need to divide the total amount of cubes that will fit in the box by 2 to find the number of cubes in each layer...

24 / 2 = 12 cubes

Finally, we can see that each layer within the box will contain 12 cubes

I'm having trouble solving the system of linear equations. This is the system: 5x + 6y = 50 x - 6y = -26 Can you please help me? Don't give the answer, but can you just explain?

Answers

Answer:

y = 5 ; x = 4

Step-by-step explanation:

Given :

5x + 6y = 50 - - - (1)

x - 6y = -26 - - - (2)

From (2)

x = - 26 + 6y

Put - 26 + 6y for x in (1)

5(-26 + 6y) + 6y = 50

-130 + 30y + 6y = 50

-130 + 36y = 50

-130 - 50 = - 36y

-180 = - 36y

y = 180 / 36

y = 5

Put y =5 in x = - 26 + 6y

x = - 26 + 6(5)

x = - 26 + 30

x = 4

y = 5 ; x = 4

Answers

Answer:

a. 18

b.144

c.108

Step-by-step explanation:

Using the given, Angle R equal 5x-54 and Angle T is 8u.

Also RS is congruent to ST. Since SR is congruent to ST, their opposite angles are also congruent using base angle theorem. So angle R is equal to Angle T. However, STU is a exterior angle so STU isn't congruent to SRT.

However, we can add , interior angle T, and STU to 180 to find x.

Interior angle T=SRT so interior angle t=5x-54.

Set up equation

[tex]5x - 54 + 8x = 180[/tex]

[tex]13x - 54 = 180[/tex]

[tex]13x = 234[/tex]

[tex]x = 18[/tex]

b.Plug 18 into 8x

[tex]8(18) = 144[/tex]

STU=144

c. Using the triangle exterior angle theorem, the exterior angle is equal to the measure of the sum of two non adjacent angles.

Angle S and Angle R are the non adjacent angle to STU.

So we cast up this equation.

[tex]5x - 54 + s = 180[/tex]

plug 18 in for x

[tex]5(18) - 54 + s = 144[/tex]

[tex]90 - 54 + s = 144[/tex]

[tex]36 + s = 144[/tex]

s=108

How would you calculate the area of the quarter circle represented in the upper left hand corner of this figure?

(see pictures for answer options)

Answers

Answer:

Step-by-step explanation:

To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.

Answer: [tex]\frac{\pi *r^{2} }{4}[/tex]

Step-by-step explanation:  We know that the formula for the area of a whole circle is πr². A quarter circle is one-fourth of a circle, so if we divide the area of the whole circle into four, we can find the area of the quarter circle: [tex]\frac{\pi *r^{2} }{4}[/tex]

Consider the sequence 1, –3, 9, –27, 81, … Which statement describes the sequence?
The sequence diverges.
The sequence converges to 0.
The sequence converges to 1.
The sequence converges to ∞.

Answers

Answer:

There is a similar problem with the same numbers except with no negatives so it goes 1 , 3 , 9 , 27, 81 for this question the answer is that it diverges.

Step-by-step explanation:

It was on the unit test review for edge and the answer was that it diverges.

This is about  understanding the behavior limits of sequence.

The sequence diverges.

The given sequence is;

1, –3, 9, –27, 81,...

Now, from the sequence above, we can see that each number is multiplied by -3 to get the next one in the sequence.

From mathematical definition, A divergent sequence is one in which the values are approaching an infinite value which could either be positive or negative whereas if it is a convergent sequence it will be approaching 0.

In this sequence given, we can see that the values are increasing to either positive or negative and as such it will keep changing till an infinite positive or negative value which corresponds with the definition of a divergent sequence as earlier defined.

• Thus, the sequence is a divergent one.
