The Smiths spend 6% of their budget on entertainment. Their total budget this year is $2,000 more than last year, and this year they plan to spend $2,760 on entertainment. What was their total budget last year? Their total budget last year was?

Answers

Answer: Their total budget last year was $44,000.

Step-by-step explanation:

Given: Smiths spend 6% of their budget on entertainment.

Total budget this year = $ 2000 more than last year.

Let x = Budget for this year.

Money on entertainment = 0.06x = 2760

[tex]\Rightarrow\ x=\dfrac{2760}{0.06}= \$46,000[/tex]

⇒ Budget for this year = $ 46,000

Budget for last year = $ 46,000 - $2,000 = $44,000

Hence, their total budget last year was $44,000.

February 29th is on Sunday. on what day will the next February 29th be?​

Answers

Answer: Friday

Step-by-step explanation:

If February 29th is on a Sunday, then, the day that the next February 29th will fall on will be Friday.

First and foremost, we should realise that February has 28 days but in leap years which takes place every 4 years, it has 29 days.

We should realise that the dates in the calendar are arranged in such a way that if a particular date falls on a particular day this year, the date will fall on the next day next year. e.g. since January 20 falls on. Wednesday this year, it will fall on a Thursday next year.

Since February 29 is a date for a leap year, following the above explanation, if February 29th is on a Sunday, then, the day that the next February 29th will fall on will be Friday which is in the next four years.

Determine the solution to the system of equations:
x = 2y - 5
3y + x = 10

Answers

Answer:

In this system of equations, x is equal to one, and y is equal to three.

Step-by-step explanation:

We can solve this by rearranging either equation to define either x or y, and plugging that into the other.  As it happens, the first equation is conveniently arranged to define x, so let's use that:

3y + x = 10

3y + (2y - 5) = 10

5y - 5 = 10

y - 1 = 2

y = 3

Now that we know the value of y, we can plug it in to either of the original equations to find x:

x = 2y - 5

x = 2(3) - 5

x = 6 - 5

x = 1

Now we can check that our answer is correct by plugging that x value into either of the original equations:

3y + x = 10

3y + 1 = 10

3y = 9

y = 3

And because that gives us our original y value, we know that our answer is correct.

Luke invested $2400 in two accounts. The first account pays 3% simple interest. The second account pays 3% compound interest with interest compounded annually(at the end of each year) After 10 years how much will the second account be worth than the first account?

Answers

The first account would be 720 in simple interest and the second account would be 3238.32 so subtracting would give 2518.32 more with than the first account. Comment if you need the full workings

The second account (compound interest) is worth more than the first account (simple interest) is $105.4.

What is compound interest?

Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.

What is simple interest?

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

Luke invested $2400 in two accounts.

The first account pays 3% simple interest.

The second account pays 3% compound interest with interest compounded annually(at the end of each year) After 10 years.

The interest from the first account will be

[tex]\rm Simple \ Interest = \dfrac{2400*3*10}{100} = \$720[/tex]

The interest from the second account will be

[tex]\rm Compound \ interest = 2400(1.03)^{10} - 2400\\\\Compound \ interest = \$825.4[/tex]

Then the second account be worth more than the first account will be

→ $825.4 – $720 = $105.4

Answers

Answer:

[tex]17.3\:\mathrm{m^2}[/tex]

Step-by-step explanation:

Solution 1:

As the angles are marked, the figure forms a 30-60-90 right triangle with the height. Therefore the height will be  [tex]\frac{4}{2}\cdot\sqrt{3}=2\sqrt{3}[/tex]. The area of this figure can be given as [tex]b\cdot h[/tex], therefore our answer is [tex]5\cdot 2\sqrt{3}\approx \fbox{$17.3$}[/tex].

The figure forms two triangles when cut by the shortest diagonal. The area of a triangle can be given by [tex]\frac{1}{2}ab\sin C[/tex]. Since there are 2 of these triangles, the area of the entire figure is [tex]2\cdot\frac{1}{2}\cdot4\cdot 5\cdot \sin 60^{\circ}\approx \fbox{$17.3$}[/tex].

plz help me find answer. what are the coordinates of slope when y= x/1–x² when dy/dx=1​

Answers

Step-by-step explanation:

dy/dx

= d/dx [x / (1 - x²)]

= [(1 - x²)(1) - (x)(-2x)] / (1 - x²)²

= (1 + x²) / (1 - x²)².

When dy/dx = 1, (1 + x²) / (1 - x²)² = 1.

=> 1 + x² = 1 - x²

=> 2x² = 0, x = 0.

Also when x = 0, y = (0) / [1 - (0)²] = 0.

Hence the coodinates is (0, 0).

Your school is going to have a free dress day if 80% of students do their homework. There are 300 students at your school and 210 of them did their homework. What percent of students did their homework last week?

Answers

Answer: 70 % of students did their homework last week.

Step-by-step explanation:

Given :

Total students = 300

Students who did their homework  = 210

Percentage of students who did their homework = [tex]\frac{\text {Students who did their homework}}{\text {Total students}}\times 100\%[/tex]

Putting the values we get:

Percentage of students who did their homework = [tex]\frac{210}{300}\times 100\%=70\%[/tex]

Thus 70 % of students did their homework last week.

Answers

Answer:

Approximately 0.6009

The value of tan 31 is 0.6008606.

What is Trigonometry?

The branch of mathematics concerned with specific functions of angles and their application to calculations.

As, the angle 31° lies between and 90° (First quad).

So, tangent function is positive in the first quadrant.

Tan 31 degrees= tan (0.54105 . . .) in radians.

As, using degree to radian conversion,

θ(radians) = θ in degrees × (π/180°)

31 degrees = 31° × (π/180°) rad

= 0.5410

So, tan 31°

= tan(0.5410)

= 0.6008606.

Hence, tan 31= 0.6008606.
