Answer:

88.85 Sq m

Step-by-step explanation:

For rectangle:

Length = 18 - 7.8 = 10.2 m

Width = 7.8 m

For both semicircular arcs:

Radius (r) = 7.8/2 = 3.9 m

Area of the shaded region = Area of rectangle + 2*Area of a semicircle - Area of circle with radius 3.5 m

[tex] = lb + 2 \times \frac{1}{2} \pi \times {(3.9)}^{2} - \pi \times {(3.5)}^{2} \\ \\ = 10.2 \times 7.8 + \pi \{{(3.9)}^{2} - (3.5)^{2} \} \\ \\ = 79.56 + \pi {(3.9 + 3.5)} (3.9 - 3.5) \\ \\ = 79.56 + 3.14 \times 7.4 \times 0.4 \\ \\ = 79.56 + 9.2944 \\ \\ = 88.8544 \\ \\ \approx 88.85 \: {m}^{2} [/tex]

The total interest on a 5-year 5.2% loan with a principal of $10,000 is $2600. The calculation is true.

Simple interest is a quick and easy way to calculate a loan's interest charge. Simply multiplying the daily interest rate by the principal by the number of days between payments yields simple interest.

Given that the amount of $10000 is deposited at the interest rate of 5.2% for the 5 years.

The simple interest is calculated by the formula written below,

SI = ( P x R x T ) / 100

SI = ( 10000 x 5.2 x 5 ) /100

SI = $2600

Answer:

X=-6

Step-by-step explanation:

the sum of interior angels in a triangle is 180.

52+78=130

180-130=50

to get 56 to 50 x has to be negative

hope this helps :)

Answer:

Ok I'll save ur life, thank me later-

52 + 56+x + 78 = 180(Since all angles in a triangle sum upto 180°)

=130 + 56+x =180

=186+x=180

=x=180-186

x=-6

56 + (-6)

=50

My father is 42 years old as obtained from the cubic polynomial's real root.

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

let my age be x years.

So, My mother is (x + 25) and my father is (x + 28) years.

∴ {x(x + 25)(x + 28) = 32130.

(x² + 25x)(x + 28) = 32130.

x³ + 53x² + 700x = 32130.

x³ + 53x² + 700x - 32130 = 0.

Now solving this has only one real solution x = 17.

So, My father is (17 + 25) = 42 years old.

2/3*80

Step-by-step explanation:

2/3*80, is the same as finding 1/3 of 80, and subtracting the new number from 80.

In Egypt British rule had important political and economic effects. The main interest of the British in Egypt was to keep control of the trade route that ran through Egypt to the Red Sea and then on to India.

Answer:

Let "x" be the number of people who can go to the amusement park.

So we have: 19 + 14x ≤ 180. This inequality basically means that the parking cost plus the cost of the tickets for every person cannot cost more than 180 dollars.

Solving this inequality, we get:

19 + 14x ≤ 180

14x ≤ 161

x ≤ 11.5

Obviously, we know that we can't have "half" a person, so the most people who can come to the amusement park would be 11 people, and the answer would be: x ≤ 11

Hope this helps!
