After watching baking shows on T.V., Angie signs up for a cake-decorating class. To practice her new skills, she decorates a batch of cupcakes with sugar flowers. Angie puts 4 sugar flowers on each cupcake. In all, Angie puts 32 sugar flowers on the cupcakes.
Which equation can you use to find the number of cupcakes c Angie decorates?
Solve this equation for c to find the number of cupcakes Angie decorates.
Answers
Angie decorates 8 cupcakes after putting 4 sugar flowers on each cupcake.
To find the number of cupcakes c Angie decorates, we can use the equation:4c = 32where 'c' is the number of cupcakes Angie decorates.
4 represents the number of sugar flowers Angie puts on each cupcake, and 32 is the total number of sugar flowers Angie puts on the cupcakes.
To solve this equation for c, we need to isolate c on one side of the equation. We can do this by dividing both sides of the equation by 4. This gives us:c = 8
Therefore, Angie decorates 8 cupcakes.Here's how we get to this answer:4c = 32Divide both sides by 4 to isolate c:c/4 = 32/4c = 8

A golfer completed 18 holes with a total of 79 strokes. On each hole, he met par, which was either four or five each time. How many holes were played in four-strokes?
Answers
Answer:
11
Step-by-step explanation:
Let a= times he hit 4 par
Let b = times he hit 5 par
a+b=18 => 4a+4b = 72
4a+5b=79
b=79-72=7
So a = 11
answer:
18 = 4a + 5b = 79, b = 79 - 72 = 7 → 11 holes

Write an equation that expresses the following relationship.
P varies with D and U and inversely with V
In your equation, use K as the constant of proportionality
Answers
The relationship "P varies with D and U and inversely with V" can be written mathematically as:
P = K * (D * U) / V
where K is the constant of proportionality.
This equation shows that P is directly proportional to the product of D and U, and inversely proportional to V. As V increases, P decreases, while as D or U increase, P also increases, assuming all other variables remain constant. The constant of proportionality K is determined by the specific situation and the units used for each variable.

Please give me the answer ASAP The average of 5 numbers is 7. If one of the five numbers is removed, the average of the four remaining numbers is 6. What is the value of the number that was removed Show Your Work
Answers
Answer:
The removed number is 11.
Step-by-step explanation:
Given that the average of 5 numbers is 7. So you have to find the total values of 5 numbers :
\(let \: x = total \: values\)
\( \frac{x}{5} = 7\)
\(x = 7 \times 5\)
\(x = 35\)
Assuming that the total values of 5 numbers is 35. Next, we have to find the removed number :
\(let \: y = removed \: number\)
\( \frac{35 - y}{4} = 6\)
\(35 - y = 6 \times 4\)
\(35 - y = 24\)
\(35 - 24 = y\)
\(y = 11\)
Okay, let's slightly generalize this
Average of \(n\) numbers is \(a\)
and then \(r\) numbers are removed, and you're asked to find the sum of these \(r\) numbers.
Solution:
If average of \(n\) numbers is \(a\) then the sum of all these numbers is \(n\cdot a\)
Now we remove \(r\) numbers, so we're left with \((n-r)\) numbers. and their. average will be \({\text{sum of these } (n-r) \text{ numbers} \over (n-r)}\) let's call this new average \( a^{\prime}\)
For simplicity, say, sum of these \(r\) numbers, which are removed is denoted by \(x\) .
so the new average is \(\frac{\text{Sum of } n \text{ numbers} - x}{n-r}=a^{\prime}\)
or, \( \frac{n\cdot a -x}{n-r}=a^{\prime}\)
Simplify the equation, and solve for \(x\) to get,
\( x= n\cdot a -a^{\prime}(n-r)=n(a-a^{\prime})+ra^{\prime}\)

Someone please answer!! What is the surface area in yards squared of the triangular prism shown below?
Answers
Answer:
1,120 yd²
Step-by-step explanation:
Surface area of the triangular prism = (bh) + (s1 + s2 + s3)*L
Where,
b = 15 yd
h = 8 yd
s1 = 17 yd
s2 = 15 yd
s3 = 8 yd
L = 25 yd
Substitute
Surface area = (15*8) + (17 + 15 + 8)*25 = 120 + 40*25 = 120 + 1,000
Surface area = 1,120 yd²

Which of these events is not mutually exclusive?
A) the chance that you will get a heads or tails when you flip a coin once.
B) the chance that you will only study for the test alone or with a friend.
C) the chance that you will meet your friends for pizza or at a chinese restaurant for dinner today at 6.
D) the chance that you will answer the ringing phone or take a walk.
Answers
The chance that you will get a heads or tails when you flip a coin once (option A) is not mutually exclusive.
Mutually exclusive events are events that cannot occur at the same time, or that do not have any overlap. In the case of flipping a coin, the possibility of getting a head and the possibility of getting tails are independent of each other, and both can occur simultaneously. Therefore, the chance that you will get heads or tails when you flip a coin once is not mutually exclusive.
On the other hand, the other events listed (B, C, and D) are mutually exclusive. The chance that you will only study for the test alone or with a friend cannot occur simultaneously, as you can either study alone or with a friend, but not both. Similarly, the chance that you will meet your friends for pizza or at a Chinese restaurant for dinner today at 6 cannot occur at the same time, as you can either go to the pizza place or the Chinese restaurant, but not both. And the chance that you will answer the ringing phone or take a walk cannot occur simultaneously, as you can either answer the phone or take a walk, but not both.

The chance that you will get a heads or tails when you flip a coin once (option A) is not mutually exclusive.
this question is related to probability.
mutually exclusive
Mutually exclusive events are those events that do not occur at the same time.
For example, when a coin is tossed then the result will be either head or tail, but we cannot get both the results. Such events are also called disjoint events since they do not happen simultaneously.
probability
Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

What is Distribution Property?
Distribution property is used in a format like a ( b + c ). To simplify these kinds of expressions, we multiply the outside term by each of the inside terms. So in this instance, a ( b + c ) is equal to ab + ac.
Let's put this in the expression3x ( 2x - 8 ) + 4x
Let's use what we learned above, and multiply the outside term (-3x) by each of the inside terms.
-3x · 2x + (-3x) · (-8) +4x
Simplify by multiplication:
-6x² + 24x +4x
Finally, we add:
-6x² +28x
Now, to simplify further, we can look for terms that show up in numbers.
We can see that the variable x is present in each of the terms, so we can factor that out, removing it from the term as follows:
x ( -6x + 28)
We can look and see that 2 is also a common factor between the two terms, so we can take that out too.
2x ( -3x + 14)
This is the most simplified it can get.

Si a y b son 2 números reales positivos tales que 1/a+1/b igual a 8/3 y a²+b²=5/2 determine el valor de a*b
Answers
Por métodos de resolución de sistemas de ecuaciones no lineales, el valor de a · b tal que a y b son números reales positivos es igual a 3 / 4.
¿Cómo determinar el producto de dos números reales positivos?
En esta pregunta encontramos un sistema de dos ecuaciones no lineales con dos variables y se nos solicita determinar el producto de dos números reales positivos. Por la ley de signos conocemos que el producto de dos números de igual signo es igual a un número positivo. El sistema es el siguiente:
1 / a + 1 / b = 8 / 3 (1)
a² + b² = 5 / 2 (2)
De (1):
(b + a) / (a · b) = 8 / 3
(a + b)² / (a · b)² = 64 / 9
(a² + 2 · a · b + b²) / (a · b)² = 64 / 9
a² + 2 · a · b + b² = (64 / 9) · (a · b)²
(a² + b²) + 2 · a · b = (64 / 9) · (a · b)²
(2) en (1):
5 / 2 + 2 · a · b = (64 / 9) · (a · b)²
(64 / 9) · (a · b)² - 2 · a · b - 5 / 2 = 0
128 · (a · b)² - 36 · a · b - 45 = 0
Por la fórmula cuadrática encontramos las siguientes raíces:
(a · b)₁ = 3 / 4, (a · b)₂ = - 15 / 32
Solamente la primera raíz satisface las condiciones del problema.

From the top of a lighthouse 82 m tall, a guard sees two ships at sea.
The angle of depression to the closer ship is 53° and to the further ship is 39°.
How far are the ships apart from each other to the nearest metre?
Answers
The distance between the two ship based on the angle of depression is 42 meters.
The distance of each ship can be calculated thus:
TanX = opposite / Adjacent
The first ship:
Tan53 = distance/ 82
distance= 108.82 meters
The second ship:
Tan39 = distance/ 82
distance= 66.40 meters
The Difference between the ships are :
108.82 - 66.40 = 42.42 metersTherefore, the distance between the two ships is 42 meters.
