There are 80 sundaes possible using one flavor of ice cream and three different toppings.

Here, we are given that a club is hosting an ice cream sundae party with four different flavors of ice cream and six different toppings.

For choosing 1 flavor of ice cream from 4, we have 4 ways.

Now, we need to choose 3 different toppings from the given 6.

This can be done in 6C3 ways

6C3 = 6! / (3! × 3!)

= (6 × 5 × 4) / (3 × 2)

= 120/ 6

= 20

Thus, we have 20 ways of choosing 3 different toppings.

Now, the number of ways of making the sundaes would be-

4 × 20

= 80

Thus, there are 80 sundaes possible using one flavor of ice cream and three different toppings.

What is Set Theory?

We study sets and their characteristics in the area of mathematical logic known as set theory. A set is a collection of things or a group of things. These things are frequently referred to as elements or members of a set. A set is, for instance, a group of cricket players. A set is a clearly defined collection of things or people, as we already learnt in the introduction. Numerous examples from everyday life, such as the number of rivers in India and the colors in a rainbow, can be used to relate sets.

Given,

Total no of people =116

No of people visiting any of the three places = total - people visiting none of the places

= 116 -14 = 102

No of people visiting only Gateway arch = total people visiting gateway arch - (people visiting all the three +  people visiting Gateway ans museum butnot zoo +people visiting gateway and zoo butnot museum)

= 66 - (18+9+14) = 25

Similarly, people visiting only zoo = 14

Step-by-step explanation:

The unit rate per batch of cookies is 2.75 as Lennon uses 5 1/2 cups of flour for every 2 batches of cookies she bakes.

To calculate the unit rate, divide the denominator by the numerator so that the denominator equals 1. For example, if 50 kilometers are reached in 5.5 hours, the unit rate is 50 kilometers/5.5 hours = 9.09 kilometers per hour.

When expressed as a fraction, a unit rate has a denominator of one unit. To write a rate as a unit rate, divide the rate's numerator and denominator by the rate's denominator.

Based on the given conditions, formulate:

(5 1/2)/2

We have to find the common denominator and write the numerators above the common denominator.

(((5×2)/2)+(1/2))/2

Now, we have to calculate the product or quotient:

((10/2)+(1/2))/2

Now, write the numerators over common  denominator,

((10+1)/2)/2

Then, calculate the sum or difference:

(11/2)/2

=11/4

=2.75 (or) 2 3/4

Therefore, the unit rate per batch of cookies is 2.75.

Answer:

  B/A = 1/2

Step-by-step explanation:

You want the scale factor between the two figures shown.

The scale factor is the ratio of the length in one figure to the corresponding length in the other figure. Often, we're interested in the scale factor B/A, which is what A dimensions need to be multiplied by in order to match the B dimensions.

You can pick any corresponding dimensions. Often, it is convenient to choose a short one, so you don't have to count so many grid squares.

We can choose the line from the center, where the lines cross, up and to the right to the upper right corner. In the A figure, that line goes 2 squares to the right and 2 squares up. In the B figure, that line goes 1 square right and 1 square up. Then the scale factor is ...

  (B dimension)/(A dimension) = 1/2

We can choose to look at the lengths of that line (A: 2√2; B: √2), or the x-dimension (A: 2; B: 1) or the y-dimension (A: 2; B: 1). All the measurements are proportional, so we get the same ratio for any pair of corresponding measures.

The scale factor B/A is 1/2.

__

Additional comment

The horizontal magenta lines in the attached figure are another possibility for determining the scale factor. B/A = 2/4 = 1/2.

You need to be careful to understand what scale factor you want. Sometimes it is described as "A to B", which can be ambiguous.

Here, the ratio of an A dimension to a B dimension is A : B = 2 : 1. The same wording can be interpreted to mean "the scale factor that multiplies A to transform it to B." That is the scale factor we have shown.

The scale factor of the figure of the two squares is 1.5

The scale factor is determine using division

The formula involve:

let the scale factor be r then we say

area of square A * r = area of square B

8 * 8 * r = 12 * 12

64r = 144

r = 144 / 64

r = 1.5

using the dimensions

8r = 12

r = 12 / 8

Answer:  9 hours

Step-by-step explanation:

here are a couple of things to notice here. You don’t have a starting temperature, so that will be an unknown. I will call it S.

The next thing to notice is that the current temperature (C) at any given time is just the starting temperature minus 4 times the number of hours (H) that have passed since 1 PM.

C = S – 4*H

We want to solve this for H when the current temperature (C) is -1.

-1 = S – 4*H

You can rearrange this by adding 4*H to both sides and adding 1 to both sides:

4*H = S + 1

Then you divide both sides by 4

H = (S+1)/4

This will tell you the number of hours PAST 1 PM that it takes to get to -1 degrees. Of course, you need to know the starting temperature, S, in order to get a numeric answer.

Let’s check this with an example. If the starting temperature were exactly 4 degrees above -1, then it should take exactly 1 hour. So let S = -1 + 4 = 3. If you plug 3 in for S, you do see that H becomes 1 hour PAST 1 PM (2 PM).

Answers to both the subparts are as follows:

(A) In order to factor A(t), we obtain A(t) = -cost + 1.

(B) t = 1.57 after solving the equation A(t) = 0 for 0 ≤ t ≤ 2.

Two expressions are combined by the equal sign to form a mathematical statement known as an equation.

For instance, a formula might be 3x - 5 = 16.

After solving this equation, we learn that the value of the variable x is 7.

(A) Factorize A(t):

A(t) = 2cost - 3cost + 1

After assembling the cost terms, we have:

A(t) = cost(2 - 3) + 1

A(t) = cost(- 1) + 1

A(t) = -cost + 1

In order to factor A(t), we obtain A(t) = -cost + 1.

(B) Solving equation A(t) = 0 for 0 ≤t≤ 2:

Since A(t) = -cost + 1

When we solve A(t) = 0 for 0 ≤ t ≤ 2, we get:

A(t) = 0

-cost + 1 = 0

-cost = -1

cost = 1

If we take the inverse cosine, we get:

t = cos⁻¹(1)

t = π/2

t = 3.142/2

t = 1.571

t ≅ 1.57

t = 1.57 after solving A(t) = 0 for 0 t 2

What is area of the triangle?

The total area that is bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to 1/2 of the height times the base, or A = 1/2 b h. Therefore, we need to know the triangular polygon's base (b) and height (h) in order to calculate its area.

Suppose

x is the shorter leg of the triangle.

As the longer leg of a right triangle is three times as long as the shorter leg.

⇒ 3x is the longer leg of the triangle.

The hypotenuse of the triangle is, √5.

By using Pythagorean theorem,

[tex]x^2 + (3x)^2 = (\sqrt{5} )^2\\x^2 + 9x^2 = 5\\10x^2 = 5\\x^2 = \frac{5}{10}\\ x^2 = \frac{1}{2} \\x = \frac{1}{\sqrt{2} }[/tex]

⇒ Shorter leg of the triangle is 1/√2.

⇒ Longer leg of the triangle is 3/√2.

Now to find the area of the triangle.

Area of triangle = [tex]\frac{1}{2}(\frac{1}{\sqrt{2} })(\frac{3}{\sqrt{2} } )[/tex]

What is surcharge?

Surcharges are extra fees or taxes, as the name implies. A 10% surcharge on a 30% tax rate effectively increases the total tax burden to 33%. A 10% surcharge is added to the tax obligation for people whose net taxable income exceeds Rs 1 crore. The surcharge is increased to 5% if the net income is greater than Rs 10 crore. If a company's net income surpasses Rs. 1 crore and Rs. 10 crore, they are both provided a margin of relief.

Solution Explained:

Given,

m = 12

d = 3.5

P(z<x) = 0.99 = ¢(Z)

Z = 2.33

Since Z = (x - m)/d

x = dZ + m

x = 3.5*2.33 + 12

x = 20.155 lb approximately

x = 20.2 lb

Therefore, the highest weight for 99% if the parcels is 20.2 lb.
