find the shaded area
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]

Your mother is 25 years older than you. Your father is 3 years older than your mother. The product of all three ages are 32,130. How old is your father?
Explanation would be appreciated!
My father is 42 years old as obtained from the cubic polynomial's real root.
What is a factor of a polynomial?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.

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)

finished the first one don´t understand these.
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!

i had this answer on my test and if i dont get it right sorry
The total interest on a 5-year 5.2% loan with a principal of $10,000 is $2600. The calculation is true.
What is simple interest?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
