How many terms are in the algebraic expression 14m-8.8n+5p-1

The volume of the square pyramid is: 3072 ft³

What is the volume of the square pyramid?

The volume (V) of a square pyramid can be calculated using the formula:

V = ⅓ × base area × height

The base area of a square pyramid is given by the formula:

base area = base edge²

Given that the base edges (a) is 24 ft and the slant height (s) is 20 ft, we can calculate the height (h) of the pyramid using the Pythagorean theorem.

h = √(20² - (24/2)²)

h = √256

h = 16 ft

Thus:

Volume = ⅓ * 256 * 16

Volume = 3072 ft³

You can use the fact that 1 quart is equal to 32 ounces.

Next, you can use the division fact, 32 divided by 4 equals 8.

And so, Celia can make 8 smoothies.

Final answer:

The calculation shows that 70 students at Riverview Elementary walk to school.

Explanation:

The question is asking us to calculate what fraction of the total number of students at Riverview Elementary walk to school each day.

Since one fifth of the students walk to school, we need to divide the total number of students by 5 to find the number of students who walk to school.

To find one fifth of 350 students, we calculate:

350 ÷ 5 = 70

Therefore, 70 students walk to school each day at Riverview Elementary.

[tex]cos(60^o)=\frac{a}{12}[/tex]

Step-by-step explanation:

The complete question in the attached figure

we know that

In the right triangle of the figure

The cosine of the angle of 60 degrees is equal to divide the adjacent side to the angle of 60 degrees (BC) by the hypotenuse (AB)

so

[tex]cos(60^o)=\frac{BC}{AB}[/tex]

we have

[tex]BC=a\ units\\AB=12\ units[/tex]

substitute the values

[tex]cos(60^o)=\frac{a}{12}[/tex]

The correct equation that represents the side length is Cos 60 = a/12

From the triangle given, we have the following

Using the soh cah toa identity

Cos theta = adj/hyp

Cos 60 = a/12

Hence the correct equation that represents the side length is Cos 60 = a/12

The value of B = [tex]\dfrac{1}{16}[/tex]

The value of C =  [tex]\dfrac{25}{16}[/tex]

The value of D =  [tex]\dfrac{5}{4}[/tex]

Step-by-step explanation:

Given as :

The following relations are as

[tex]\dfrac{d}{5}[/tex] =4 A           ...........1

d = 20 B                                       ...........2

d = [tex]\dfrac{4}{5}[/tex] C           ...........3

And d = [tex]\dfrac{5}{4}[/tex]

d = [tex]\dfrac{4}{5}[/tex] C  

Put the value of d

So, [tex]\dfrac{5}{4}[/tex] =  [tex]\dfrac{4}{5}[/tex] C    

Or, C = [tex]\frac{5\times 5}{4\times 4}[/tex]

∴ C = [tex]\dfrac{25}{16}[/tex]

Answer

Answer:

0 ≤ t ≤ 5.

Step-by-step explanation:

In the function [tex]f(t)[/tex], [tex]t[/tex] is the independent variable. The domain of [tex]f[/tex] is the set of all values of [tex]t[/tex] that this function can accept.

In this case, [tex]f(t)[/tex] is defined in a real-life context. Hence, consider the real-life constraints on the two variables. Both time and volume should be non-negative. In other words,

The first condition is an inequality about [tex]t[/tex], which is indeed the independent variable.

However, the second condition is about [tex]f[/tex], the dependent variable of this function. It has to be rewritten as a condition about [tex]t[/tex].

[tex]\begin{aligned} f(t) &\ge 0 &&\text{Assumption} \cr 80000 - 16000\, t& \ge 0 && \text{Definition of} ~ f \cr 80000 & \ge 16000\, t && \begin{aligned}&\text{Add $16000\, t$} \\[-0.5em] & \text{to both sides of the inequality}\end{aligned} \cr 5 &\ge t &&\begin{aligned}&\text{Divide both sides of} \\[-0.5em] & \text{the inequality by $16000$}\end{aligned} \cr t &\le 5 && \text{Flip the inequality}\end{aligned}[/tex].

Hence, t ≤ 5.

Combine the two inequalities to obtain the domain:

0 ≤ t ≤ 5.

Answer:

[tex]f^{-1}[/tex](x) = x - 5

Step-by-step explanation:

Let y = f(x) and make x the subject

y = x + 5 ( subtract 5 from both sides )

y - 5 = x

Change y back into terms of x, thus

[tex]f^{-1}[/tex](x) = x - 5

The inequalities that require flipping the sign are:

-5x - 10 > 5

[tex]\frac{x}{-7} + 3 \leq 4[/tex]

Solution:

Let us the inequalities one by one

You can perform on operations on both sides of inequality, and have its truth value unchanged

But if we multiply or divide by a negative number , we must flip the sign

-5x - 10 > 5

Move -10 from L.H.S to R.H.S

-5x > 5 + 10

-5x > 15

Divide the above expression by 5

[tex]-x > 3[/tex]

Divide the above inequality by -1, so we must flip the sign

x < -3

[tex]7x - 5 \leq 16[/tex]

Move the constant term from L.H.S to R.H.S

[tex]7x \leq 16 + 5\\\\7x \leq 21\\\\[/tex]

Divide the above inequality by 7

[tex]x \leq 3[/tex]

This does not required flipping the symbol

[tex]\frac{x}{5} - 6 > -11[/tex]

Move the constant term from L.H.S to R.H.S

[tex]\frac{x}{5} > -11 + 6\\\\\frac{x}{5} > -5[/tex]

Multiply both the sides by 5

[tex]x > -25[/tex]

This does not required flipping the symbol

[tex]x + 12 \leq 29[/tex]

Move the constant term from L.H.S to R.H.S

[tex]x \leq 29 - 12\\\\x \leq 17[/tex]

This does not required flipping the symbol

[tex]\frac{x}{-7} + 3 \leq 4[/tex]

Move the constant term from L.H.S to R.H.S

[tex]\frac{x}{-7} \leq 4-3\\\\\frac{x}{-7} \leq 1\\\\[/tex]

Multiply both the sides by -7, so we must flip the sign

[tex]x \geq -7[/tex]

Thus this requires flipping the sign

Answer:

AB ║ CD. (Proved)

Step-by-step explanation:

See the attached diagram of the triangle.

It is given that Δ ACD is an isosceles triangle.

Therefore, AC = AD and ∠ ACD = ∠ ADC, ⇒ ∠ 3 = ∠ 4 .......... (1)

Again, given that ∠ 1 = ∠ 3 ........... (2)

Now, from equations (1) and (2) we can write, ∠ 1 = ∠ 4

Now, AB and CD are two straight lines and AD is the transverse line and hence, ∠ 1 and ∠ 4 are alternate angles that are equal.

Therefore, AB and CD are parallel straight lines and AB ║ CD. (Proved)

Answer:

x =15°

Step-by-step explanation:

Given that the horizontal line is 90° to the vertical line, then both the angles have to necessarily add up to 90° i.e

(5x-10)° + 25° = 90°

5x - 10 + 25 = 90

5x + 15 = 90  (subtract 15 from both sides)

5x = 90 - 15

5x = 75   (divide both sides by 5)

x = 75 / 5 = 15°

Answer:

1) angle bisector

2) w = 72°

3) t = 44°

4) t = 51°

5) FG = 16 units

Step-by-step explanation:

1) Given that, ∠VYW ≅ ∠WYV

The line which cuts any angle into equal halves is angular bisector of the angle

⇒ YW is angle bisector

2) In a triangle, sum of two interior angle is equal to exterior angle of other side.

⇒ w-41° + w-31° = w.

⇒ w = 72°

3) Sum of interior angles in a pentagon is 540°

(For a n sided it is (n-2)180° )

⇒ 149° + 139° + t+32° + 3t +t = 540°

⇒ t = 44°

4) sum of all exterior angles taken one at each vertex = 360°

⇒ 2t-50° + 46° + 2t + 34° + 2t-50° + 34° + 40° = 360°

⇒ t = 51°

5) Here, by comparing ΔHGF and ΔHIF

   ∠GHF = ∠IHF

  ∠HGF = ∠HIF

 and HF is common side for both triangles

⇒  ΔHGF ≡ ΔHIF ;  i.e) ΔHGF , ΔHIF are congruent triangles

⇒ FG = FI = 16 units

Answer:

The percentage change in volume between cylinder A and cylinder B is 50%

Step-by-step explanation:

The volume of a cylinder is given by the formula

V= πr^2h

For cylinder A, where r=7 and h= 5, π=22/7

V= π * 7^2 * 5

V= π * 49 * 5

V= 769.69 cubic inch

For cylinder B

V= 490π

V= 1539.3804 cubic inch

The percentage change in volume between cylinder A and cylinder B

=[ (VA- VB)/VB] *100

=( 1539.3804 - 769.69) / 1539.3804

= 0.5000 * 100

= 50%

The percentage change in the volume between cylinder A and cylinder B is 50%

A cylinder is a three-dimensional object. It is a prism with a circular base.

volume of a cylinder = πr²h

π=  22/7

r = radius

h = height

Volume of cylinder A = π(7² x 5) = 245π

Percentage change in volume = (245 / 490) - 1 = 50%

The placebo effect describes how a person might show improvement simply because they believe a treatment is working, even if it's a dummy treatment. It's an essential aspect considered during clinical studies to distinguish between actual treatment effects and the impact of patients' expectations.

The placebo effect is best described as the phenomenon in which a person experiences a perceived improvement in their condition or symptoms simply due to their belief in the efficacy of the treatment, even if the treatment is inactive or a 'dummy' treatment, such as a sugar pill. This is represented in the provided choices by option B. Subjects may respond to a treatment simply because they believe it is affecting them.

Notably, this effect is considered in the design of clinical trials and studies. This is typically done by using a control group that receives a placebo treatment, which allows researchers to separate the physiological effects of the treatment from psychological effects induced by expectations- a crucial aspect of medical and scientific research.
