The Area of Kitchen is 120 square feet.

We have,

Area of living room = 144 square feet

So, the dining room

= 1/3 (area of living room)

= 1/3 (144)

= 48 square feet

and, Area of Dining room = 2/5 x Area of kitchen

48 =  2/5 x Area of kitchen

Area of kitchen = 48 x 5/2

Area of Kitchen = 24 x 5

Answer:

60

Step-by-step explanation:

The area of a parallelogram is base x hight.

A = bh

10(b) x 6(h) = 60

Step-by-step explanation:

a) 11*5=55

15*5=75

8*5+5=45

b) No, because (55+75+45=175°) and the perimeter of a triangle is 180°

The solution in the equation is x = 12.

We have,

To solve the logarithmic equation log (x − 2) = 1,

We can use the definition of logarithm which states that log base b of x equals y if and only if b to the power of y equals x, where b is the base of the logarithm.

In this case, the base is not specified, so we assume it is 10, which is the common base used in most calculators and mathematical applications

Using the exponential form, we have:

log (x - 2) = 1

10^1 = x - 2

10 = x - 2

x = 12

Therefore,

The solution is x = 12.

The time it will take the bird to travel 1.4 m is 0.5738 seconds.

In Science and Mathematics, velocity can be defined as the distance covered by an object per unit of time in a specific direction. This ultimately implies that, velocity is a vector quantity because it has both magnitude and direction.

In Mathematics and Science, the velocity of any a physical object can be calculated by using this formula;

Velocity = distance/time

244 cm/s to m = 244/100 = 2.44 cm/s

By making time the subject of formula, we have:

Time = distance/velocity

Time = 1.4/2.44

Time = 0.5738 seconds.

The instantaneous velocity of the train at t = 9 seconds is approximately 6.8 m/s

To estimate the instantaneous velocity of the train at t = 9 seconds, we can consider the average velocities over several small intervals of time that include the point t = 9. This is an approximation of the slope of the tangent line to the curve s(t) at t = 9, which is the instantaneous velocity.

We can calculate the average velocity over each interval by dividing the change in displacement by the change in time:

Average velocity from [8.5, 9] = (s(9) - s(8.5)) / (9 - 8.5) = (8√9 + 1 - 8√8.5 + 1) / 0.5 = 6.34 m/s (approx.)

Similarly, we can calculate the average velocities over the other intervals:

[8.7, 9]: 6.48 m/s (approx.)

[8.9, 9]: 6.60 m/s (approx.)

[8.99, 9]: 6.66 m/s (approx.)

[9, 9.01]: 6.67 m/s (approx.)

[9, 9.1]: 6.74 m/s (approx.)

[9, 9.3]: 6.87 m/s (approx.)

[9, 9.5]: 7.00 m/s (approx.)

As we consider smaller intervals closer to t = 9, the average velocities approach a limit, which is the instantaneous velocity at t = 9. In this case, we see that the average velocities are increasing as we approach t = 9, indicating that the instantaneous velocity at t = 9 is also increasing.

Based on these calculations, we can estimate that the instantaneous velocity of the train at t = 9 seconds is approximately 6.8 m/s (averaging the average velocities from [8.99, 9] to [9, 9.5]).

The simplification of the given expression is equal to 192524.3.

The expression is equal to,

√2 × √6 × √110 × √120 × √450 × √520

Simplify this expression by first simplifying the square roots under the radical signs,

√2 = √(2 × 1)

     = √2 × √1

√6 = √(2 × 3)

     = √2 × √3

√110 = √(2 × 5 × 11)

        = √2 × √5 × √11

√120 = √(2 × 2 × 2 × 3 × 5)

        = 2√2 × √3 × √5

√450 = √(2 × 3² × 5²)

         = √2 × (3 × 5)²

         = 15√2

√520 = √(2³ × 5 × 13)

        = 2√2 ×√5 × √13

Substituting these simplifications back into the original expression, we have,

√2 × √6 × √110 × √120 × √450 × √520

= √2 × √2 × √3 × √2 × √5 × √11 × 2√2 × √3 × √5 × 15√2  ×  2√2 ×√5 × √13

= 2⁵ × 3² × 5²√(5 × 11  × 13)

The equation will have the solution in the form of an imaginary number "i" as: x = (3 ± 2i)/2

In a quadratic equation, an imaginary number is a complex number that can arise when trying to take the square root of a negative number.

We shall solve for x in the equation as follows:

(2x + 3)² - 2 = -6

add 2 to both sides

(2x + 3)² = 2 - 6

(2x + 3)² = -4

2x + 3 = √(-4) {taking square root of both sides}

subtract 3 from both sides

2x = 3 ± √(-4)

divide through by 2

x = [3 ± √(-4)]/2

note that: √(-4) = √(1-) × √4 where √(-1) = I, so;

x = (3 ± 2i)/2.

The required rate of simple interest is 1.75%.

Here, we have,

(Principal + Interest) is a straightforward interest equation.

A = P(1 + rt)

Where: A is the sum of the accrued principal and interest.

Principal Amount is P.

I is the interest rate.

r is the annual percentage rate of interest, or R/100.

R is the annual percentage rate of interest; R = r * 100 t is the length of time involved in months or years.

Since I = Prt,

the initial formula A = P(1 + rt) evolved from A = P + I to A = P + Prt,

which may be represented as A = P(1 + rt).

Given: Principal is $1,300

Rate is 7% and the amount earned that is A-P is $159.25.

After two years, Swathu will pay back the debt in full, which comes to Rs. 105287.27.

To find the total amount Swathu will pay back after 2 years on a loan of Rs. 90,000 with an interest rate of 8% per annum compounded half-yearly, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^{nt[/tex]

where:

A = the total amount Swathu will pay back

P = the principal amount borrowed (Rs. 90,000)

r = the annual interest rate (8%)

n = the number of times the interest is compounded per year (2 times, since it is compounded half-yearly)

t = the time period (2 years)

Substituting these values into the formula, we get:

[tex]A = 90,000(1 + 0.08/2)^{2*2}\\\\A = 90,000(1 + 0.04)^4\\\\A = 90,000(1.04)^4\\\\A = 90,000(1.16985856)\\[/tex]

A = 105287.27 (rounded to the nearest tenth)
