What is the value of x​

Equation that can be used to represent the number of visits Violet must make to earn a free movie ticket is:

2.5v+45=75

A formula that expresses the equality of two expressions, by connecting them with the equals sign '= 'is called an equation

Unknowns are the variables for which the equation is solved and  unknown values that satisfy the equation are called solutions.

Firstly, multiply 2.5 by the number of visits (v) to calculate how many points Violet earned in total.

Now add 75 to the product of 2.5(v) because Violet started with 75 points.

To find out how many times Violet would require to visit the movie theater to get a free movie ticket:

Subtract 45 from 75,  that leaves you with 30, and after dividing that by 2.5, the number of points per visit comes out to be 12

Violet would need to visit the theater 12 times to earn a free movie ticket.

To check if that's right, substitute the value of 'v' in the equation,

12*2.5 + 45 = 75

Answer:

C. t = 3/5

Step-by-step explanation:

[tex]10t + 4 - 2t = 2 - 2(t - 4)[/tex]

[tex]4 + 8t = 2 - 2t + 8[/tex]

[tex]4 + 8t = 10 - 2t[/tex]

[tex]4 + 10t = 10[/tex]

[tex]10t = 6[/tex]

[tex]t = .6 = \frac{3}{5} [/tex]

Answer:

A.    Bank B

Step-by-step explanation:

First the formulae necessary to calculate compound and simple interest

P = principal = amount deposited

r = interest rate as a decimal (i%  interest => r = i/100)

t = number of years

n = number of times compounded

[tex]\text{Compound Interest }= P\left(1 + \dfrac{r}{n}\right)^{nt} - P[/tex]

In this case, we have P = 800
r = 8/100 = 0.08
n = 12 since the interest is compounded monthly
t = 2 years

So compound interest

[tex]CI = 800\left(1 + \dfrac{0.08}{12}\right)^{12 \times 2} - 800\\\\CI = 800(1.00667)^{24} - 800\\\\\\CI = 938.31 - 800\\\\CI = $138.31[/tex]

For Bank B, the interest is calculated at 9% annually and the interest is given by the formula
SI = P x r x t
SI = 800 x 0.09 x 2    (r = 9%/100 = 0.09)

SI =  $144.00

So depositing in bank B is preferred

Doug dives a total distance of 6.8 meters from the platform to the bottom of the sea.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

We have been given that a Doug dives from a platform that is 5 meters above the water.

His dive takes him 1.8 meters below the surface of the water.

To determine the total distance Doug dived, add the height of the platform above water and the distance he dived below water.

= (5 + 1.8) meters.

= 6.8 meters.

Thus, Doug dives a total distance of 6.8 meters from the platform to the bottom of the sea.

The missing value in the solution to the equation y = -2x+4y is y.

According to the question,

We have the following information:

y = -2x+4y

y equals minus 2 x plus 4.

Now, look at the equation, we know that the solution of y is -2x+4y.

Now, the statement that is given is incomplete because we have 4 is multiplied by y.

(More to know: this equation can be further solved. We have y = -2x+4y. Now, we can move the same variables to one side. So, we have -3y = -2x. Now, the two negative signs when divided gives the positive result.)

The car will catch up the cyclist 3 hours after it starts moving.

The cyclist travels at 9 miles per hour, and travels for 4 hours before the car starts moving, so the equation for the position of the cyclist as a function of time, t, is:

C(t) = 9*4 + 9*t = 36 + 9*t

And the car moves at 21 miles per hour, then the position is:

P(t) = 21*t

The car will catch the cyclist when:

C(t) = P(t), this gives:

36 + 9*t = 21*t

36 = 21*t - 9*t = 12*t

36/12 = t

The actual distance between Dallas and Austin in miles is 180 miles.

Conversion of units means to convert between different units of measurement for the same quantity. Example of units are - m, cm, litre.

Given is the distance between Dallas and Austin on a map is about 9 centimeters. The map uses a scale in which 1 centimeter represents 20 miles.

The maps use scale in order to depict large distances with very small length measurements. As mentioned in the question - 1 cm represents 20 miles. This scale shrinks 20 miles of distance into 1 cm

Distance between Dallas and Austin on a map - 9 cm

On map - 1 cm = 20 miles

Therefore, 9 cm will be equivalent to (9 x 20) or 180 miles.

Hence, the actual distance between Dallas and Austin in miles is 180 miles.

The area of the circle of radius r centered at the origin is π[tex]a^{2}[/tex]

Since the circle is symmetrical in relation to the x and y axes, we can calculate the area of a quarter of a circle and multiply it by 4 to get the entire circle's area.

The equation y y = + mn [a 2 - x 2] must be solved.

Y = [a 2 - x 2] = a [1 - x 2 / a 2] is the equation for the upper semicircle (y positive).

Step-by-step explanation: Substitute the value of the variable into the expression and simplify

As a result, 4.8 litres of water will be in the fish tank after three minutes if the water release rate is 1.6 gallons per minute.

A linear system is a mathematical representation of a system in systems theory that relies on the application of a linear operator. Compared to nonlinear systems, linear systems often have significantly simpler traits and properties. Linear systems are widely used in automatic control theory, signal processing, and telecommunications as a mathematical abstraction or idealization.

for 0.5 minutes , 0.8 gallons of water is required

To convert to gallons per minute, multiply by 2.

1.6 gallons per minute (0.8 x 2)

Gallons per minute multiplied by three minutes

3.0 minutes = 4.8 liters (1.6 x 3)

Therefore, 4.8 litres of water will be in the fish tank after 3 minutes if per minute water released is 1.6 gallons
