a square pyramid has a base edge of 32 inches and an altitude of 1 foot. a square pyramid whose altitude is one-fourth of the original altitude is cut away at the apex of the original pyramid. the volume of the remaining frustum is what fractional part of the volume of the original pyramid?

Answers

The fractional part of the volume of the original pyramid that remains in the frustum is 91.65%.

To find the volume of the original pyramid, we can use the formula for the volume of a square pyramid:

V = (1/3) * B * h

where B is the area of the base and h is the altitude.

The area of the base of the pyramid is:

32 inches * 32 inches = 1024 square inches, and the altitude is 1 foot = 12 inches, so the volume of the original pyramid is:

V = (1/3) * 1024 square inches * 12 inches = 4096 cubic inches.

The new pyramid that is cut away from the original pyramid has an altitude of 1/4 of the original pyramid, so the altitude of this pyramid is:

12 inches / 4 = 3 inches.

The volume of this smaller pyramid can be found using the same formula:

V = (1/3) * 1024 square inches * 3 inches = 341.3333 cubic inches.

The remaining frustum is the original pyramid with the smaller pyramid cut away, so the volume of the frustum is the volume of the original pyramid minus the volume of the smaller pyramid:

V = 4096 cubic inches - 341.3333 cubic inches

= 3744.6667 cubic inches

To find the fractional part of the volume of the original pyramid, we divide the volume of the frustum by the volume of the original pyramid and multiply by 100%

V(frustum) / V(original)

= 3744.6667 cubic inches / 4096 cubic inches = 0.9165

Therefore, the volume of the remaining frustum is 91.65% fractional part of the volume of the original pyramid.

you invest a total of $5000 between two saving accounts. account A pays 2% annual interest and account B pays 4% annual interest. after one year, you have earned a total of $135 in interest. How much did you invest in each account

Answers

The Investment in Account A is 1750, Investment in Account B is 3250

What is simple interest?

Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.

Simple Interest = (Principal × Rate × Time) / 100

Given;

The total investment = 5000

Let the amount invested in account A be x

Therefore, the amount invested in account B = 5000-x

In Account A, rate of interest = 4% per year

Thus, interest earn in one year

= x*4*1/100

= 4x/100

Now, The interest in account B = 2% per year

Thus, the interest earn in one year

= (5000-x)*2*1/100

= 2(5000-x)/100

Therefore, total interest;

(x*4*1/100)*((5000-x)*2*1/100)

(2x+10000)/100=35

x=1750

Hence, investment with interest in account A and account B will be $1750 and 5000-1750 = $3250

Answers

To make a 360mL mixture that contains 9% vinegar, use 240mL of the first brand and 120mL of the second brand.

What is an equation?

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.

You want to set up an equation that will match the word problem. Let's call the amount of the first brand, F, and the amount of the second brand, S.

We want the total mixture to be 360mL so: F + S = 360

Also, you want the total mixture to contain 9% vinegar so:

.08F + .11S = .09(360)

Now, we can solve the system of equations using substitution.

F + S = 360

.08F + .11S = .09(360)

F = 360 - S [solve 1st equation for F]

.08(360 - S) + .11S = .09(360) [substitute into 2nd equation]

28.8 -.08S +.11S = 32.4

.03S = 3.6

S = 120

F + 120 = 360 [substitute answer for S back into original equation]

F = 240

Answer: To make a 360mL mixture that contains 9% vinegar, use 240mL of the first brand and 120mL of the second brand.

Answers

The total price of the phone including the tax is $35.97.

What is a percentage?

The percentage is calculated by dividing the required value by the total

value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Price of the phone = $33

Tax = 9%

The total price of the phone.

= 33 + 9% of 33

= 33 + 9/100 x 33

= 33 + 2.97

= $35.97

Thus,

The total price of the phone is $35.97.

What is Probability ?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Basic Probability Properties are :

P(E) = [Number of favorable outcomes of E]/[Total number of possible outcomes of E] is the formula for calculating an event's probability.The likelihood of a given occurrence or a sure thing happening is 1.There is no chance that an impossible occurrence will occur.A number P(E) that has the formula 0≤ P(E)≤ 1 represents the probability of an occurrence E. The probability scale is always positive.If events A and B are two occurrences that can never occur together, then P(A∪B) = P(A) + P (B).An basic event is one that has just one result. The total likelihood of such outcomes in an experiment is 1, or 1.

The probability of a house valued less than $ 500, 000 is

(P < $500,000) = P(X<$250,000) + P($250,000 <x <$500,000)

The first step in solving a system of equations is to solve one of the equations with a variable.

A collection of one or more linear equations containing the same variables is known as a system of equations. When the graphs do not meet, there is no solution to a system of linear equations. When the graphs of the equations overlap at all locations, there can be an endless number of solutions or just one when they do not.

Solving one of the equations for one of the variables in terms of the other variable is the first step in solving a system of equations by substitution.

The total amount of money in the savings account after 3 years will be $1,614.00. This is calculated by multiplying $1500 by 1.04 three times, which equals $1,614.00.

1. 1500 x 1.04 = 1560

2. 1560 x 1.04 = 1624.40

3. 1624.40 x 1.04 = 1683.76

4. 1683.76 rounded to two decimal places = $1,614.00

Annie invests $1500 in a savings account that earns 4% simple interest annually. After 3 years, the amount of money in the savings account can be calculated by multiplying the initial investment of $1500 by 1.04 three times. This results in a total of $1,614.00 in the savings account after 3 years, without any additional deposits or withdrawals. This is because 4% simple interest annually means that the interest earned each year is 4% of the initial investment. This is calculated by multiplying the initial investment by 1.04. The 1.04 is the amount of interest earned which is then added to the initial investment. This process is repeated for 3 years, resulting in the total of $1,614.00.

How do you find the distance between two points in fractions?

Answers

Answer:

√((x2-x1)^2 + (y2-y1)^2)

Step-by-step explanation:

To find the distance between two points in fractions, you can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

To use the Pythagorean theorem to find the distance between two points, you can think of the two points as the endpoints of one of the legs of the right triangle. Let the two points be (x1, y1) and (x2, y2). The distance between the two points is the length of the hypotenuse of the right triangle formed by the two points and the origin. The distance can be computed using the formula:

distance = √((x2-x1)^2 + (y2-y1)^2)

This will give you the distance between the two points in whatever unit you are using for x and y.

How many distinct solutions does the following equation have x1 x2 x3 x4 100?

Answers

The given equation has 161700 distinct solution.

If a sum of non-negative integers whose values is pre-defined say m is equal to a fixed value say n such that:x1+x2+x3+...+xm=nthen the total combination of m non negative integersx1,x2,...xmin mathematical form can be written as:n+m−1Cm−1.

The above problem can also be written as:

x1+x2+x3+x4=100x1≥1x2≥2x3≥0x4≥0

Herex3 and x4 are non-negative integers and there is a restriction onx1 and x2.

Removing the restriction onx1 and x2 as:100 - 1 - 2 = 97

The number of distinct solution that the equationx1+x2+x3+x4=100has is equivalent to the non-negative solution. ofx1+x2+x3+x4=97 and is given by:

97+4−1C4−1=100C3=161700

Hence, the number of distinct solution that the equationx1+x2+x3+x4=100 has is 161700.

To find solution of equation

The solutions of equations basically depends on the power of variables present on it .

The solutions of equations also show that the how much the power of variables Is present that times it cuts the axis .

For example

1.if x+2=0 then x=—2 that means it has one solution and it also means it cut the x -axis one time .

2.if x^2–4=0 then x have two values that is x=+2,x=—2 it also means it cut the x-axis two times

Similar for power is 3 then it have three solution.

And so on for if power is n then it have solutions .
