A builder is putting floor tiles on each of the 15 kitchen floors in an apartment building. Each floor uses 40 tiles. Each floor tile costs $7.

How much does the builder spend on the floor tiles?

Final answer:

The house will be worth $153,420 when it is 16 years old, calculated by finding the annual increase in value from the given data and projecting this increase over the relevant time period.

Explanation:

To calculate the worth of the house when it is 16 years old, we need to establish the rate at which the house's value is increasing over time, based on the information given for its value at 2 years and at 7 years. The house is valued at $125,000 when it is 2 years old and $135,150 when it is 7 years old, showing an increase of $10,150 over 5 years.

First, we find the annual increase in value by dividing the total increase by the number of years:

Annual increase = $10,150 / 5 = $2,030.

Next, we predict the value when the house is 16 years old by multiplying the annual increase by the number of years from the starting point (2 years old) to 16 years old:

14 years (from year 2 to year 16) × $2,030 annual increase = $28,420 increase since year 2.

Finally, we add this increase to the original value at year 2:

Projected Value at Year 16 = $125,000 + $28,420 = $153,420.

Hence, according to the model, the house will be worth $153,420 when it is 16 years old.

Answer:

The two numbers are 25 and 15.

Step-by-step explanation:

Let's find out the two numbers, this way:

x = first number

y = second number

This is the equations system:

x + y = 40

x - y = 10

Solving for x in the first equation:

x + y = 40

x = 40 - y

Solving for y in the second equation:

40 - y - y = 10

40 - 2y = 10

-2y = 10 - 40

-2y = - 30

y = -30/-2 = 15

Solving for x:

x + y = 40

x + 15 = 40

x = 40 - 15

x = 25

The two numbers are 25 and 15.

Answer:

[tex]y =-\frac{1}{3}-2[/tex]

Step-by-step explanation:

We are given;

We are required to determine the equation a line passing through a point (6, -4) and perpendicular to the given line;

y = 3x -3

But; m₁ × m₂ = -1 (For perpendicular lines)

Therefore;

m₂ = -1 ÷ 3

    = -1/3

Therefore, the slope of the line in question is -1/3 and the line passes through (6, -4).

To get its equation, we get another point (x, y)

Then;

[tex]\frac{y+4}{x-6}=\frac{-1}{3}[/tex]

Thus;

[tex]3(y+4) = -1(x-6)\\3y + 12 = -x+6[/tex]

In the form of slope-intercept, the equation will be;

[tex]3y = -x - 6\\y =-\frac{1}{3}-2[/tex]

Thus, the equation of the line is;

[tex]y =-\frac{1}{3}-2[/tex]

We can extend 352.83 and write as  (3 x 100) + (5 x 10) + (2 x 1) + (8/10) + (3/100)

Step-by-step explanation:

Considering the given value 352.83 we can expand that step by step as,

(3 x 100) which will give us a value of 300.

Now adding the multiplied answer of (5 x 10) will give us 350.

Next we can also add the multiplied answer of (2 x 1 ) which will further give us 352.

Now adding the divided answer of (8/10) we will get 352.08

Finally adding the divided answer of (3/100) we will get the exact value of 352.83 as mentioned above.

The expanded notation for the number [tex]352.83[/tex] is [tex](3\times 100)+(5\times 10)+(2\times 1)+(8\times \dfrac{1}{10})+(3\times \dfrac{1}{100})[/tex]

A number can always be written in the expanded notation by multiplying the face value with the face notation.

Here, [tex]3[/tex] is at the [tex]100th[/tex] place of the number so, it can be written as [tex]3\times 100[/tex].

Similarly, the digits which are located after the decimal point can be expanded by dividing the face value of the number by [tex]10[/tex] raised to the power of face notation.

Here, [tex]8[/tex] is present just after the decimal point and so, its expanded form is [tex]8\times \dfrac{1}{10}[/tex].

Hence, the expanded notation of  [tex]352.83[/tex] is [tex](3\times 100)+(5\times 10)+(2\times 1)+(8\times \dfrac{1}{10})+(3\times \dfrac{1}{100})[/tex].

Step-by-step explanation:

Assuming that you need to simplify the expression, below is the explanation to do it.

Given the following expression:

[tex]-\frac{1}{3}\sqrt{-90}[/tex]

You need to decompose the radicand (The number inside the square root) into its prime factors:

[tex]90=2*3*3*5=2*3^2*5[/tex]

Knowing that, you can rewrite the expression in this form:

[tex]=-\frac{(1)(\sqrt{-2*3^2*5})}{3}=-\frac{\sqrt{-2*3^2*5}}{3}[/tex]

Since [tex]\sqrt{-1}=i[/tex], you must substitute it into the expression:

[tex]=-\frac{i\sqrt{2*3^2*5}}{3}[/tex]

Now you need to remember the following property:

[tex]\sqrt[n]{a^n}=a^{\frac{n}{n}}=a[/tex]

Then, applying that property, you get:i:

[tex]=-\frac{3i\sqrt{2*5}}{3}=-\frac{3i\sqrt{10}}{3}[/tex]

Ex: Babken has 10 meters left, Cecilia is 9 meters behind.

So, the answer is 10+9=19.

19 meters.

Cecilia's position is  19 m behind when Arman is at the finish line.

Arman, Babken, and Cecilia 3 decided to compete in a 100m run.

Distance is defined as the difference in position.

Here,

Cecilia covers 90% of Babken's covered distance. Babken Covered 90% of Arman distance. So distance covered by Cecilia is.
= 90/100 * 90/100 x 100
= 81m

Now, distance between Cecilia and Arman when he crossed the finish line,
= 100m-81m

Answer:11

Step-by-step explanation:

Add 18 and 15 then find the GCF

The maximum number of pots she can make is 15.

The process of subtracting one number from another is known as subtraction.

Given that, Tina has 18 sunflower seeds and 15 daisy seeds.

Since Tina wants to distribute the sunflower seeds and daisy seeds equally in each pot, each pot must contain at least one daisy seed and one sunflower seed.

Therefore, if, she has 1 daisy seed and 1 sunflower seed in each pot, then she can make 15 pots, as there are only 15 daisy seeds.

Now, there are only 3 sunflower seeds left but she cannot use them to make a pot as there are no daisy seeds.

Hence, the maximum number of pots she can make is 15.

So the algebraic expressions is :

Hey there! :)

~ They give us some good information in this equation. Let's use it! This can be used to change "45 min" into ".75 hours".

~ Now, let's write an equation; "distance = speed * time."

~ 3(.75) + .5x = 6

~ 2.25 + .5x = 6

Final answer:

To find Jess's running speed, the total distances she walked and ran are calculated and added to equal the given total distance of 6 km. Solving the equation 6 km = 2.25 km + 0.5x km reveals that Jess ran at 7.5 km/h.

Explanation:

To find the value of x, which represents Jess's running speed, we can use the information provided to set up equations based on the distance formula: distance = speed × time.

Jess walked for 45 minutes at 3 km/h. First, convert 45 minutes to hours by dividing by 60: 45 minutes / 60 minutes/hour = 0.75 hours. The distance walked is:

Distance walked = Speed × Time = 3 km/h × 0.75 hours = 2.25 km.

Next, Jess ran for 30 minutes or 0.5 hours at x km/h. The running distance is:

Distance ran = Speed × Time = x km/h × 0.5 hours = 0.5x km.

According to the question, the total distance from the starting point after both activities is 6 km, so:

Total distance = Distance walked + Distance ran

6 km = 2.25 km + 0.5x km

Now, solve for x:

6 km - 2.25 km = 0.5x

3.75 km = 0.5x

x = 3.75 km / 0.5

x = 7.5 km/h

Therefore, Jess ran at 7.5 km/h.
