MAVERICK [17]

Answer:

Your answer is 10

Step-by-step explanation:

So if you have to pay 55 out front and then continue to pay 19.50 monthly the equation will look like this:

19.50*m + 55 = x

(M stands for month)

She has 250 dollars to spend so add that in for x

19.50*m + 55 = 250.

Use inverse operations.

250-55 and 55-55

19.50*m = 195

195/19.50 and 19.50/19,50

m=10

Your answer is 10

A company produces fruity drinks that contain a percentage of real fruit juice. Drink A contains 20% real fruit juice and Drink

ddd [48]

Answer:

Therefore the company made 510 liters of Drink A and (510+80)=590 liters of Drink B.

Step-by-step explanation:

Let, the company make x liters of drink A

The company makes drink B of (80+x) liter. Since the company make 80 more liters of Drink B than liters Drink A .

Given drink A contains 20% real fruit.

Therefore x liters of drink A contains $=\frac{20}{100}\times x$ liters $=\frac{x}{5}$ liters real fruit.

Drink B contains 5% real fruit juice.

(80+x) liters of drink B contains $=\frac{5}{100}\times (80+x)$ liters $=\frac{80+x}{20}$ liter real fruit.

The company used 56.5 liters of real fruit juice to make Drink A and Drink B.

According to the problem,

$\frac{80+x}{20}+\frac{x}{5}= 56.5$

$\Rightarrow \frac{80+x+4x}{20}=56.5$

⇒80+5x = 56.5×20

⇒80+5x=1130

⇒5x=1130-80

⇒5x=1050

$\Rightarrow x=\frac{1050}{5}$

⇒x=510

Therefore the company made 510 liters of Drink A and (510+80)=590 liters of Drink B.

Find the general solution to the homogeneous differential equation. d2ydx2−1dydx−30y=0 d2ydx2−1dydx−30y=0 Use c1c1 and c2c2 in y

lukranit [14]

Answer:

The general solution of second order homogeneous differential equation is $y(x)=c_1e^{6x}+c_2e^{-5x}$

Step-by-step explanation:

To find the general solution of this second order homogeneous differential equation $\frac{d^2y}{dx^2}-\frac{dy}{dx}-30y=0$ we are going to use this Theorem:

Given the differential equation $a \ddot{y}+b\dot{y}+cy =0, a\neq 0$ , consider the quadratic polynomial $ax^2+bx+c$ , called the characteristic polynomial. Using the quadratic formula, this polynomial always has one or two roots, call them $r$ and $s$ . The general solution of the differential equation is:

(a) $\ds y=Ae^{rt}+Be^{st}$ if the roots $r$ and $s$ are real numbers and $r\not=s$ .

(b) $\ds y=Ae^{rt}+Bte^{rt}$ , if $r=s$ is real.

(c) $\ds y=A\cos(\beta t)e^{\alpha t}+B\sin(\beta t)e^{\alpha t}$ , if the roots $r$ and $s$ are complex numbers $\alpha+\beta i$ and $\alpha-\beta i$
