Answer:

Value of house in 2017  = 231525$

Explanation:

 At the start of 2014 worth of Lucy's house = 200000$

 Rate of increase of the value of the house = 5% = 0.05

 Value of house in 2015 = 200000+0.05*200000 = 210000$

 Value of house in 2016 = 210000+0.05*210000 = 220500$

 Value of house in 2017 = 220500+0.05*220500 = 231525$

 Number of years in between 2014 and 2017 = 2017 - 2014 = 3 years.

 Value of house in 2017 [tex]=200000*1.05^3=231525$[/tex]

Answer:

Step-by-step explanation:

13,501 rounded to the nearest ten thousand is 14,000. This is because if you look at the 3, the number next to it is 5, causing it to round up. Numbers 0-4 are rounded down, and numbers 5-9 are rounded up.

Answer:

10,000

Step-by-step explanation:

When we round a number to the nearest ten thousand we check the digit at the thousand place,

If the digit ≥ 5,

The number is rounded to next ten thousand,

If the digit < 5,

The number is rounded to previous ten thousand.

Here, the given number,

13,501,

Digit at thousand place = 3 ( < 5 )

Thus, 13,501 ≈ 10,000 ( nearest ten thousand )

Answer:

6 appointments are cancelled per day

Step-by-step explanation:

Question says  4 out of 24 appointments are cancelled.

It means out of 1 appointment , the cancelled appointments = [tex]\frac{4}{24}[/tex]

=[tex]\frac{1}{6}[/tex]

Now the questions says each day there are 36 appointments

And we have to find how many appointments got cancelled each day,

It means we have to find how many appointments got cancelled out of 36 appointments each day

So we multiply 36  by [tex]\frac{1}{6}[/tex]

=[tex]36 * \frac{1}{6}[/tex]

= 6

Hence , 6 appointments got cancelled each day.

Jasmine has 6 appointments cancelled per day, determined by scaling the given cancellation ratio (4 out of every 24) to match the number of daily appointments she books (36).

To answer this question, we first need to understand the rate at which appointments are cancelled. The problem states that 4 out of every 24 appointments are cancelled. To find out how many appointments are cancelled each day, we use this ratio and apply it to the 36 appointments that Jasmine books each day.

First, we need to scale the ratio to match Jasmine's daily bookings. To do this, we multiply the numerator and denominator of the ratio by 36/24, which is 1.5. This gives us a new ratio of 6 cancellations for every 36 appointments.

So, each day, out of the 36 appointments that Jasmine books, 6 appointments are cancelled.

Answer:

-3

Step-by-step explanation:

The question requires matching verbal descriptions of numbers with their corresponding numeric representations using decimal notation. The place value of each digit is used to determine the correct numeric form of the verbal description.

When matching the verbal descriptions to the correct number sentences, you will use the value of each place within a number to write it in decimal notation. For example, in the number 1837, the digit 7 is in the ones place (10⁰ = 1), the digit 3 is in the tens place (10¹ = 10), the digit 8 is in the hundreds place (10² = 100), and the digit 1 is in the thousands place (10³ = 1000). This helps us correctly identify the number sentences.

If the two equations intersect at [tex](50,60)[/tex] then this point must satisfy the two equations.

[tex]3x+2y=270---(1)[/tex]

We substitute  [tex](50,60)[/tex]  in to erquation (1)

[tex]3(50)+2(60)=270[/tex]

[tex]150+120=270[/tex]

[tex]270=270[/tex]

[tex]y=\frac{4}{5}x+20 ---(2)[/tex]

We now substitute  [tex](50,60)[/tex]  in to erquation (2) also

[tex]60=\frac{4}{5}(50)+20[/tex]

[tex]60=40+20[/tex]

[tex]60=60[/tex]

Since the point satisfy all the two equations, it is true that they intersect at [tex](60,50)[/tex]

The fourth graph represents the function.

We have to rewrite the given function into the standard form of a parabola.

A parabola is a U-shaped plane curve that is symmetrical about its vertex.

The standard form of a parabola is given by:

y = (x-h)²+k

Where (h,k) is the vertex of the parabola.

f(x) = x²+2x-1

We can rewrite this as:

f(x) = x²+2x+1-2

f(x) =( x+1)²-2

Now compare this with the given graphs. The only graph that has its vertex at (-1,-2) is the fourth graph.

We have found the graph that represents the function f(x) = x²+2x-1 to be the fourth graph.

Measure of ∠P = 60°

Step-by-step explanation:

Consider triangle PMO.

Since PM is perpendicular to MO , hence m∠PMO = 90°

Also given that m∠MOP = m∠2 = 30°

And since sum of three angles of a triangle is 180°

⇒ m∠PMO + m∠MOP + m∠MPO = 180°

⇒m∠MPO = 180° - (m∠PMO + m∠MOP) = 180° - ( 90 + 30 ) = 60°

Hence m∠MPO that is m∠P is 60°

Answer:

m 2 = 30°, m P = 60

The correct choice is 60

Problem 1

Plug in x = 0 and solve for y to get the y intercept

6x+12y = 60

6(0)+12y = 60

12y = 60

12y/12 = 60/12 ... divide both sides by 12

y = 5

Step-by-step explanation:

From the given figure, it can be seen that TG and LI are the chords of the circle with center O such that TG=LI=10.4 which means that TG is congruent to LI.

Also, OE and OH gives the shortest distance(perpendicular) of the chord LI and TG respectively from center of circle O.

And, We know that "the congruent chords are equidistant from the center of a circle."

Therefore, we can conclude that, OH is congruent to OE.

Hence, option (A) is correct.

From the figure we can conclude that OH is congruent to OE.

The perimeter of a shape is the sum of all visible side lengths of the shape. The perimeter of polygon qrst is 16 units.

Given that:

[tex]q = (-3,2)[/tex]

[tex]r = (1,2)[/tex]

[tex]s = (1,-2)[/tex]

[tex]t = (-3,-2)[/tex]

First, we calculate the distance between the vertices using distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

So, we have:

[tex]qr = \sqrt{(-3- 1)^2 + (2 - 2)^2} = \sqrt{16} = 4[/tex]

[tex]rs = \sqrt{(1- 1)^2 + (2 - -2)^2} = \sqrt{16} = 4[/tex]

[tex]st = \sqrt{(1--3)^2 + (-2 - -2)^2} = \sqrt{16} = 4[/tex]

[tex]tq = \sqrt{(-3--3)^2 + (-2 -2)^2} = \sqrt{16} = 4[/tex]

The perimeter (P) is the sum of all sides:

[tex]P = qr + rs + st + tq[/tex]

[tex]P = 4 + 4 + 4 + 4[/tex]

[tex]P = 16[/tex]

Whole numbers are a subset of integers, which in turn are a subset of rational numbers.

So, every whole number is an integer, and every integer is a rational number.

So, it is possible for a rational number not to be an integer. Think of any decimal number: 1.356 is a rational number, but it's not an integer.

On the other hand, if a number is not an integer, it can't be a whole number, because all whole numbers are integers.

Number of units purchased = 117

Amount paid to purchase 117 units = $ 1250

Selling price of 117 units = $ 1601

Here, let us assume that all the units were sold at the same price.

So, profit on 117 units = [tex]1601-1250= 351[/tex]

Now, profit per unit will be,

[tex]\frac{351}{117} =3[/tex]

Hence, the profit earned per unit is $3.
