Answer:

From a search on google, the first part of this problem is:

Kelsey has to pay $200 to rent a booth at the craft fair. The materials for each  pendant cost $7.80, and she plans to sell each pendant for $13.50. To make  a profit, she must make more money than she spends. Kelsey has already  made 10 pendants.

We know that:

I takes Kelsey 5 hours to make 12 pendants.

She works 8 hours per day, for 3 days.

then she works a total of 24 hours.

We want to find the number of pendants that she can make in that time, first, how many groups of 5 hours there are in 24 hours?

(24h/5h)

And in each one of those groups, she can make 12 pendants, this means that the total number of pendants that she will make is:

(24h/5h)*12 = 57.6 pendants.

And we should round it down to 57 pendants because 0.6 of a pendant does not make sense.

Now let's calculate the profit.

Remember that the profit is the difference between the revenue and the costs.

The costs will be:

C(x) = $200 + $7.80*x

Where x is the number of pendants that she made.

In these 3 days, she made 57 pendants, plus 10 that she did before, she has 67 pendants, then x = 67.

C(67) = $200 + $7.80*67 = $722.60

And the revenue will be:

R(x) = $13.50*x

for the 67 pendants:

R(67) = $13.50*67 = $904.50

Then the profit will be:

P = R - C = $904.50 - $722.60 = $181.90

So yes, her profit will be a lot more than the minimal of $50 asked in the question.

The speed of Becca for the given data is 3/2 miles per hour.

The distance that an object travels in relation to the amount of time it takes to do so can be used to define speed. In other terms, it is a measurement of an object's motion's speed without direction The term "velocity" refers to the combination of direction and speed.

Given the hiking distance of Becca = 9/10 miles

time taken = 3/5 hours

to find the speed,

speed = distance/time

speed = (9/10) ÷ (3/5)

speed = 9/10 x 5/3

speed = 3/2 miles per hour

Hence the speed of Becca is 3/2 miles per hour.

3.28833605E+18 (Scientific Notation, for example, aE+b = a × 10^b) [ 3,288,336,052,853,678,818 ]

Step-by-step explanation:

123-20+8,098*67^8 =

(123 - 20) + (8,098 × 67^8)

103 + (8,098 × 67^8)

103 + 3,288,336,052,853,678,715 [3.28833605285367815E+18] =

3,288,336,052,853,678,818 [3.28833605285367815E+18]

≈ 3.28833605E+18

This is due to the order of operations, that defines the mathematical steps to solve arithmetic problems. This is known as PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction).

So each part of the expression must be worked out in a certain order to get the correct answer.

Answer:

x = 3

Step-by-step explanation:

(x - 1)2 + 2 = x + 3

~Distribute left side

2x - 2 + 2 = x + 3

~Combine like terms

2x = x + 3

~Subtract x to both sides

x = 3

An arts academy requires there to be 3 teachers for every 57 students and 4 tutors for every 44 students. How many students does the academy have per​ teacher? Per​ tutor? How many tutors does the academy need if it has ​121 students?

Answer:

a)19 students per teacher

b)11 students per tutor

c)11 tutors if they have 121 students

Step-by-step explanation:

An arts academy requires there to be 3 teachers for every 57 students and 4 tutors for every 44 students.

a) How many students does the academy have per​ teacher?

3 teachers for every 57 students

3 teachers = 57 students

1 teacher = x

Cross Multiply

3x = 1 × 57 students

x = 57 students/3

x = 19 students

Hence, we have 19 students per teacher

b) How many students Per​ tutor?

4 tutors for every 44 students.

4 tutors = 44 students

1 tutor = x students

Cross Multiply

4x = 44 × 1

x = 44/4

x = 11 students.

This means that we have 11 students per tutor

c) How many tutors does the academy need if it has ​121 students?

4 tutors for every 44 students.

44 students = 4 tutors

121 students = x

Cross Multiply

x = 121 × 4/44

x = 11 tutors

Hence, the school would need 11 tutors if they have 121 students

Answer: 88

Step-by-step explanation:

First use the distributive property.

4(15 + 7) can turn into 4(15) + 4(7)

Then we simplify until we get the answer.

4(15) = 60

4(7) = 28

Then it is...

60 + 28

Just add them together...

60 + 28 = 88

So the answer is 88. I hope this helps, and I hope it's not wrong, but I do not think it is.

Step-by-step explanation:

After eight years, the value of Edward's home increased by $24,386.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

Edward purchased his home for $89,000.

For the first three years after he moved in the real estate market was very lively, so his property value grew by 4.8% every year.

And,  For the next five years, the market slowed down somewhat, and his property value grew by 2.6% every year.

Now,

After three years, the value of Edward's home increased by,

⇒ 3 × (4.8% of $89,000)

⇒ 3 × (4.8/100 × 89,000)

⇒ 3 × 4,272

⇒ $12,816

And, After five years, the value of Edward's home increased by,

⇒ 5 × (2.6% of $89,000)

⇒ 5 × (2.6/100 × 89,000)

⇒ 5 × 2,314

⇒ $11,570

Thus, After eight years, the value of Edward's home increased by,

⇒ $12,816 + $11,570

⇒ $24,386
