According to the linear equations, At 4 hours both companies charge the same rate.So Company A is cheaper if the time is less than 4 hours. After 4 hours, company B is cheaper.

According to the statement

We have to find that the comparison of the linear equation.

So, For this purpose, we know that the

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

From the given information:

Company A charges $45 per hour and a $300 equipment fee. Company B charges

$70 per hour and a $200 equipment fee.

Then

Let A(t) = 45t + 300

Let B(t) = 70t + 200

We can determine time t when both companies charge the same rate by equating the two equations.

45t + 300 = 70t + 200

Subtract 25t from both sides and subtract 150 from both sides

25t = 100

Divide both sides by 25

t = 4

So, According to the linear equations, At 4 hours both companies charge the same rate.So Company A is cheaper if the time is less than 4 hours.After 4 hours, company B is cheaper.

For a 75% success percentage, she needs to hit 23 of her final 30 throws.

The rational function for a player's free throw percentage will be:

y = (21/30) * 100

A function that is the sum of polynomials is referred to as rational. If a function of one variable, x, can be written as :

[tex]f(x) = p(x)/q(x),[/tex]

where p(x) and q(x) are polynomials with q(x) = 0,

then the function is said to be rational. The phrase f(x) = (x2 + x - 2) / (2x2 - 2x - 3) denotes a rational function; in this case, 2x2 - 2x - 3 = 0.

Every constant is a polynomial, thus we know that the numerators of rational functions may also be constants. A rational function would be f(x) = 1/(3x+1), for instance.

If the basketball player is making 70% successful throw rate by making 21 of last 30 free throws

so, for raising her throw rate to 75% she should throw:

x/30 * 100 = 75%

x = 75 * 3 / 10

x = 15 * 3 /2

x = 22.5 ≈ 23

therefore , she should make 23 of her last 30 free throws to raise her success rate to 75%

For this case what you should do is write the following function:

y = (a / b) * 100

Where,

A: amount of successful free throws

B: total amount of free throws

Substituting values we have:

y  = (21/30) * 100

The result is:

Y = 70% (as we expected)

a rational function that can model the player's free throw percentage is:

y = (21/30) * 100

If a classroom has 8 light bulbs and the probability that each individual light bulb works is 0.8 and each light bulb works independently of the other light bulbs then the probability that all 8 of the light bulbs work is equal to 0.1678.

Probability is a branch of mathematics and can be defined as the one which deals with the explanation of the possibility of an event to occur or take place. Probability has a range between 0 to 1. In probability, 0 indicates the impossibility of an event to occur and 1 indicates the certainty of that event to occur or take place.

As the light bulbs are not dependent on each other and work independently, the probability that all eight of the light bulbs will work can be calculated by multiplying the probability of each of the eight light bulbs.

As the probability of each of the eight light bulbs to work = 0.8

probability all the eight light bulbs work = 0.8^8

probability all the eight light bulbs work = 0.1678

Hence, 0.1678 is the probability that all the light bulbs work.

Given that the two cities are at a distance of 381 miles and they start at 8:00 am in the morning.

We are required to find the time at which Jermaine and Brandon.

let the distance that Jermaine covers be x. In this way the distance that is covered is 381-x.

Time=Distance/speed

x/67=(381-x)/60

60x=67(381-x)

60x=25527-67x

137x=25527

x=25527/137

x=186.33

Distance that is covered by Brandon=381-186.33

=144.67 miles

Time taken by David=x/67

=186.33/67

=2.78 hours

We have to break an hour in 78% which is 46.8 minutes.

Actual time=(8+2)hours+46.8 minutes=10:46 A.M.

The highest altitude of an altocumulus cloud is 3⁹ ft in power.

Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward way.

The amount of times a number has been multiplied by itself is shown by its exponent.

Given the lowest altitude of an alto cumulus cloud is about 3⁸ feet. The highest altitude of an altocumulus cloud is about 3 times the lowest altitude.

To find the highest altitude of an altocumulus cloud, we must solve as follows:

Let the lowest altitude be x. Then,

3⁸ = x

The highest altitude will be 3x which is 3(3⁸).

⇒3(3⁸) = 3x

⇒3(6561) = 3x

Simplifying further,

⇒3x6561= 19683

⇒3 (3 x 3 x 3 x 3 x 3 x 3 x 3 x 3) = 19683

⇒3⁹= 19683

The value of a that we get after solving the expression, we get that a = - 56.

We are given the expression that:

a - 4 - 5 c = 0

We are also given that:

c = - 12

Now we will substitute the value of c in the equation.

So, we get that:

a - 4 - 5 ( -12 ) = 0

Now, we multiply the brackets, we get that:

a - 4 + 60 = 0

Now combining the like terms, we get that:

a + 56 = 0

Subtract 56 from both sides, we get that:

a + 56 - 56 = 0 - 56
