The value of Maggie's car decreased by 10% since last year, when she bought it. If the car is now worth $16,000.00, how much was the car worth when she bought it?

Step-by-step explanation:

8x-5=9+7x

8x-7x=9+5

x=14

Answer:

8x-5 = 9+7x

8x-7x =9+5

x = 14

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.

Answer:

0

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

(NegativeA) + (PositiveA) = 0

Note for future reference:

(NegativeA) + (PositiveB) = (NegativeC)

(PositiveA) + (NegativeB) = (NegativeC)

(NegativeA) + (NegativeB) = (NegativeC)

(PositiveA) + (PositiveB) = (PositiveC)

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!

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

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

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]
