Answer 1

We have the following number, we need to simplify:

[tex]6\cdot\sqrt[]{-2401}[/tex]

we can also express this as:

[tex]\begin{gathered} 6\cdot\sqrt[]{(-1)\cdot(2401)} \\ 6\sqrt[]{(-1)\cdot(49)\cdot(49)} \end{gathered}[/tex][tex]\begin{gathered} =6\sqrt[]{-1\cdot49^2} \\ =6\cdot\sqrt[]{-1}\cdot\sqrt[]{49^2} \\ =6\cdot\sqrt[]{-1}\cdot49 \\ =6\cdot49\cdot\sqrt[]{-1} \end{gathered}[/tex]

since:

[tex]\sqrt[]{-1}=i[/tex]

which represents the imaginary number,

then, we get:

[tex]6\sqrt[]{-2401}=6\cdot49\cdot i=294i[/tex]

You are serving bratwurst and hamburgers at your annual picnic. You want at least three bratwursts or hamburgers for each of your 35 guests. Bratwursts cost $1.3 each and hamburgers $1.2 each. Your budget is $150

Answers

Total cost of bratwursts + Total cost of hamburgers ≤ 150

that is 1.3x + 1.2y ≤ 150

Given,

The total number of guests = 35

Minimum number of bratwursts or hamburgers each one need = 3

The cost of bratwursts = $1.3 each

The cost of hamburgers = $1.2 each

Total budget = $150

We can take number of bratwursts as x and number of hamburgers as y.

Lets check.

Each guest need at least three food items = 35 × 3 = 105

That is, you need more than 105 food items.

So,

x + y ≥ 105

Lets see,

Total cost for bratwursts = 1.3x

Total cost for hamburgers = 1.2y

Now, your total budget is $150. So, the cost of food items must be less than or equal to 150.

That is,

Total cost of bratwursts + Total cost of hamburgers ≤ 150

1.3x + 1.2y ≤ 150

last month, using the tax rate of 15.3%.

Answers

The amount for Kai's self employment taxes for the last month is $407.745 .

In the question ,

it is given that

number of music lessons that Kai taught = 41

per music lesson charge = $65 .

Answers

Given:

The objective is to find the number.

Explanation:

Consider the unknown number as x,

First, four times the number can be written as 4x.

Twenty more than 4 time the number will be,

[tex]4x+20\ldots\ldots.\text{ (1)}[/tex]

Then, twice the number can be represented as 2x.

And the difference between 2 and twice the number will be,

Now, equate both the equations (1) and (2).

[tex]\begin{gathered} 4x+20=2-2x \\ 4x+2x=2-20 \\ 6x=-18 \\ x=\frac{-18}{6} \\ x=-3 \end{gathered}[/tex]

When are reciprocals used to solve an equation?

Answers

It's important to know that reciprocals are the multiplicative inverse of a numbers, for example, the reciprocal of 7 is 1/7.

As you can observe, using reciprocals would help to solve equations when we have to get rid off a factor. For example, if we have the equations 4x = 8, we would use the reciprocal of 4 to isolate the variable x: (4x)/4 = 8/4 then x = 2.

Therefore, reciprocals are used to move factors across the equation to isolate the variable.

Royce deposits $1200 into a savings account. After nine year, he made $3472.32.
What is the annual simple interest rate of the loan?

Answers

The interest rate needed to make $3,472.32 from simple interest on a principal of $1,200.00 over 9 years is 21.04% per year.

How to determine simple interest rate?

Simple interest is expressed mathematically as;

A = P( 1 + rt )

Where A is accrued amount, P is principal, r is rate and t is the time period.

Given the data in the question;

Principal P = $1200 Accrued amount A = $3472.3Time period t = 9 yearsInterest rate r = ?

Plug the given values into the simple interest formula and solve for r

A = P( 1 + rt )

r = (1/t)(A/P - 1)

r = ( 1/9 )( $3472.3/$1200 - 1)

r = ( 1/9 )( 2.8936 - 1)

r = ( 1/9 )( 1.8936)

r = 0.2104

Convert to percentage

r = 0.2104 × 100%

Rate r = 21.04%

Therefore, the interest rate of the loan is 21.04%.

Mellisa buys 2.5 pounds of salmon and 1.25 pounds of swordfish. She pays a total of $31.25, and the swordfish costs $0.20 per pound less than the salmon l. What would be the combined cost of 1 pound of salmon and 1 pound of swordfish.

Answers

The combined cost of 1 pound of salmon and 1 pound of swordfish is $16.60

Let $x be the cost of 1 pound of salmon.

The swordfish costs $0.20 per pound less than the salmon, then $(x-0.20) is the cost of 1 pound of swordfish.

Melissa buys 2.5 pounds of salmon and pays $2.5x for salmon.

Melissa buys 1.25 pounds of swordfish and pays $1.25(x-0.20) for swordfish.

She pays a total of $31.25, then we get an equation,

2.5x + 1.25(x - 0.20) = 31.25

We solve above equation for x.

2.5x + 1.25x - 0.25 = 31.25

3.75x = 31.50

x = 8.4

So, the cost of 1 pound of salmon is $8.40 and 1 pound of swordfish is $8.20

and combined cost = $8.40 + $8.20

Therefore, the combined cost of 1 pound of salmon and 1 pound of swordfish is $16.60

Answers

How to calculate the number of hours Megan spent dancing ?

Megan is involved in a musical production

Yesterday, she practiced for 2 3/4 hours

Today she practiced for 3 1/2 hours

The first step is to calculate the total number of hours she spent at the practice

2 3/4 + 3 1/2

= 11/4 + 7/2

The LCM between both fractions is 4

11/4 + 7/2

11 + 14/4

= 25/4

Megan spent 25/4 hours yesterday and today practicing

Out of this 25/4 hours, she spent 1/3 hours dancing

Therefore the hours she spent dancing can be calculated as follows

= 25/4 × 1/3

= 25/12

= 2 1/12

Hence Megan spent 2 1/12 hours dancing yesterday and today

The equation reads: y = 1/3x - 4/3.

Describe Line.

The points that make up a line can be extended endlessly in opposite directions. Two points along the same line are referred to as collinear points.

The slopes are the same if two lines are parallel to one another.

Consequently, line h's slope would be equal to line g's 1/3.

All that is left to do is plug the points into the formula to determine the y-intercept.

2 = 1/3(10) + b

2 = 10/3 + b

2 - 10/3 = b

2-10/3 = b

-4/3 = b

Hence, the equation for h is y = 1/3x - 4/3.

You have already traveled 30 miles east and then 30 miles north. To get back to the start, you travel 30 miles west in 1 hour and then 30 miles south in a half hour. What are your average speed and average velocity for the whole rally? Explain your answer.

Will report if answer is not related to question

Answers

Using it's concepts, the average speed and the average velocity are given as follows:

Average speed: 40 miles per hour.Average velocity: 0 miles per hour.

Average speed

The average speed is given by the quotient between the total distance traveled and the time taken, that is:

Average speed = total distance/time

In this problem, the total distance is of 60 miles(30 miles west + 30 miles south), in a time of 1.5 hours(1 hour west and 0.5 hours south), hence the average speed is given as follows:

Average speed = 60/1.5 = 40 miles per hour.

Average velocity

The average velocity is given by the quotient between the displacement and the time taken, that is:

Average velocity = displacement/time

The displacement is the difference between the final position and the initial position. Since the person got back to the start, finish = start, hence the displacement is of zero, as is the average velocity.
