Answer:

The 16 cases will fit the box as shown.

Step-by-step explanation:

One disk case has the dimensions 14.2 cm by 19.3 cm, with thickness 1.6 cm.

Temporarily ignoring the 14.2 cm and 19.3 cm measurements, we multiply this 1.6 cm thickness by 16, obtaining a total thickness for the stack of cases of 25.6 cm.  

1) The 16 cases, arranged as shown, and measuring 25.6 cm from left to right in this diagram, will fit within the 26 cm horizontal distance shown.

2) The horizontal length of each case is 14.2 cm.  Stacked as shown, the 16 cases will fit within the 15 cm depth of the box.

3) The vertical measurement of each case is 19.3 cm.  The 20 cm vertical measurement of the box can accommodate this 19.3 height within 20 cm.

All indications are that the 16 cases will fit comfortably inside the box.

Answer:

16 discs capacity of the cuboid.

Step-by-step explanation:.

for simplicity...

i would just divide 26cm to 1.6cm = 16 .25

therefore,  16 discs capacity of the cuboid.

Answer:

116.6

Step-by-step explanation:

Volume = ⅓ × area of base ×height. We don't have the area of base, we need to find it.

Perimeter (4×Length) = 16.9 cm

Length = 16.9÷4 = 4.225 cm

Area = L² = 4.225² =

Volume of pyramid = 1/3 × 4.225² × 19.6 = 116.624 = 116.6 cm³

Answer:

\(x^2 = -16y\)

Step-by-step explanation:

Given

\(Vertex = (0,0)\\Focus = (0,-4)\)

Required

Equation of the parabola (in standard form)

The standard form of a parabola is \((x - h)^2 = 4p (y - k),\)

Such that

Vertex = (h,k)

Focus = (h, k + p)

For the vertex

This implies that (h,k) = (0,0)

h = 0 and k = 0

For the focus

This implies that (h, k + p) = (0, -4)

\(h = 0\\k + p = -4\)

Recall that \(k = 0;\)

Hence, \(0 + p = -4\)

\(p = -4\)

Substitute \(p = -4\), \(h = 0\ and\ k = 0\) in the given formula

\((x - h)^2 = 4p (y - k),\) becomes

\((x - 0)^2 = 4 * -4 (y - 0),\)

\((x)^2 = 4 * -4 (y),\)

\(x^2 = -16 (y),\)

\(x^2 = -16y\)

Hence,, the standard form is \(x^2 = -16y\)

Answer:

x = 10

Step-by-step explanation:

the two angles shown are supplementary, they add up to 180 degrees

so we can write this equation to solve for 'x':

100 + 9x - 10 = 180

90 + 9x = 180

9x = 90

x = 10

Answer:

\(\tt x=10^o\)

Step-by-step explanation:

The given angles are supplementary angles, meaning they add up to 180°.

\(\tt 100+ 9x - 10 = 180^o\)

\(\tt 90 + 9x = 180^o\)

\(\tt 90+9x-90=180-90\:\: (Subtract)\)

\(\tt 9x=90\)

\(\tt \cfrac{9x}{9}=\cfrac{90}{9}\;\;(Divide)\)

Answer:

#1 = 10.71% decrease (not sure if you should write -10.71%)

#2 = 49.29% decrease (-49.29%) (-49.30% rounded)

#3 = 5.4% increase

#4 = 34.26% decrease (-34.26%. -34.27 if your teacher wants it rounded.)

Step-by-step explanation:

Original:28

New:25

Increase ÷ Original Number × 100.

28-25 =3

3/28 = 0.1071

0,1071*100= 10.71

Original:21.2

New:10.75

21.2-10.75= 10.45

10.45/21.2 = 0.4929

0.4929*100 = 49.29 (49.30)

Original:37

New:39

difference = 2

2/37 = 0.054

0.054*100 = 5.4

Original: $4.29

New:$2.82

4.29-2.82 = 1.47

1.47/4.29 = 0.3426

0.3426*100 = 34.26 (34.27)

Hope this helps! Have a great day! Also, let me know if it is correct.

Answer:

50.23 and 50.24 are both rational numbers.

Step-by-step explanation:

Rational numbers can be written like a ratio.

●Whole numbers (2, 15, 77) are rational bc just put a 1 underneath it (2/1, 15/1, 77/1) now its a ratio.

●Fractions are rational bc the fraction is exactly the ratio (1/2, 5/8, 65/111)

●Decimals that "terminate" that is end or stop are rational like your problem (50.23, 50.24) and ALSO decimals that repeat (2.33333..., 7.666666...) We can do some math on these and find the ratio that is equal to the decimal.

50.23

= 50 + 23/100

= 50•(100/100) + 23/100

= 5000/100 + 23/100

= 5023/100

50.23 is equal to 5023/100.

50.24 = 5024/100 = 2512/50 = 1256/25

Briefly, decimals that do not end either with no pattern or even with a pattern, but not repeating...they are Irrational. (pi, e, and any weird 4.531874569131187732678...no pattern, and 3.1121231234pattern but not a repeat)

Square roots of not-a-perfect square are Irrational (sqrt3, sqrt7, sqrt24) probably tmi, but hope this helps!

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Answer:

the factors of 63 are:

D. 3, 7, 9, 21, 63

Step-by-step explanation:

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Hello, for the first one, the answer should be (C) 3

The following transformation is an enlargement, meaning it would get bigger. Meaning that the scale factor increases by 3.

2x3=6

3x3=9

Therefore, the scale factor is (C) 3.

#5: The answer is (D): 4

Since this is an enlargement, we have to determine what ? x 6 = 24 is. Since the height of the photo is 6, we can conclude that 6 x 4 = 24.

Therefore, the answer is (D): 4
