Final answer:

To calculate the remaining travel time, subtract the distance already driven from the total distance and divide the result by the speed. It will take 3 hours to reach the destination.

Explanation:

The question involves calculating the remaining travel time to reach a destination, given the current distance traveled, the total distance, and the traveling speed. We're provided with the equation 55h + 275 = 440, where h represents the number of hours needed to reach the destination.

Here's how we solve the equation step-by-step:

Subtract 275 from both sides of the equation to isolate the term with h. This gives us 55h = 440 - 275.

Subtract 275 from 440 to get the remaining distance, which is 165 miles.

Divide the remaining distance by the speed to find the time in hours. So we have h = 165/55.

Calculate the division to find h = 3 hours.

Therefore, it will take 3 hours to reach the destination after having already driven 275 miles at a speed of 55 miles per hour.

The required height of the trapezoid is 11.5 inches.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.

Here,
The formula for the area of a trapezoid is:

A = (b₁ + b₂) * h / 2

where A is the area, b1 and b2 are the lengths of the two bases, and h is the height.

We are given that the area of the trapezoid is 166.75 in² and the lengths of the two bases are 21 in and 8 in. So we can plug these values into the formula and solve for h:

166.75 = (21 + 8) * h / 2

Simplifying the expression on the right side:

166.75 = 29 * h / 2

Multiplying both sides by 2:

333.5 = 29 * h

Dividing both sides by 29:

h = 11.5

Final answer:

To find the height of a trapezoid given its area (166.75 sq in) and bases (21 in and 8 in), you use the formula-

[tex]A = \frac{1}{2} h(b_1 + b_2)[/tex]

By rearranging to solve for h, you find that the height is 11.5 inches.

Explanation:

The question asks to find the height of a trapezoid given its area and bases. The area of a trapezoid is calculated using the formula A = [tex]\(\frac{1}{2}\)h(b_1 + b_2)[/tex], where A represents the area, h the height, and [tex]b_1[/tex] and [tex]b_2[/tex] the lengths of the two bases. In this case, the area is 166.75 square inches, and the bases measure 21 inches and 8 inches.

To find the height, we can rearrange the formula to-

h = [tex]\(\frac{2A}{b1 + b2}\)[/tex]

Plugging in the given values gives us-

h = [tex]\(\frac{2 \times 166.75}{21 + 8}\)[/tex]

which simplifies to-

h = [tex]\(\frac{333.5}{29}\)[/tex]

Therefore, the height of the trapezoid is 11.5 inches.

To find the total length of four 3/8-inch pieces, you multiply the length of one piece (3/8 inch) by the number of pieces (4), which equals 1.5 inches.

To calculate the total length of all the 3/8-inch pieces, we multiply the length of one piece by the number of pieces, which is 4. The mathematical expression for this is:

Total length = length of one piece x number of pieces

Total length = 3/8 x 4

To perform the multiplication, multiply the numerators and then the denominators:

Total length = (3 x 4)/(8 x1)

Total length = 12/8 inches

Now, simplify the fraction by dividing the numerator and the denominator by the greatest common divisor, which is 4:

Total length = (12/4)/(8/4)

Total length = 3/2 inches

And since 3/2 inches is equal to 1.5 inches, the total length of all four pieces is 1.5 inches.

Answer:  Sum of the geometric series will be [tex]\frac{763}{972}[/tex]

Step-by-step explanation:

Since we have given that

[tex]\frac{1}{4}+\frac{2}{9}+\frac{4}{27}+\frac{8}{81}+\frac{16}{243}[/tex]

Here,

As we know the formula for "Sum of n terms in geometric series ":

[tex]S_n=\frac{a(1-r^n)}{1-r}\\S_n=\frac{\frac{2}{9}(1-\frac{2}{3}^4)}{1-\frac{2}{3}}\\S_n=\frac{130}{243}[/tex]

So, Complete sum  will be

[tex]\frac{130}{243}+\frac{1}{4}=\frac{520+243}{972}=\frac{763}{972}[/tex]

The distance traveled by car has to travel to catch up to the train is 240 miles.

Given that,

A train travels due north at 40 mph.

A car travels toward the train from the same starting point leaving 2 hours later than the train.

If the car is traveling at 60 mph.

We have to determine,

How many miles will the car have to travel to catch up to the train?

According to the question,

The distance will the car have to travel to catch up to the train is determined by using the following formula;

[tex]\rm Speed = \dfrac{Distance}{Time}[/tex]

Let the distance will the car have to travel to catch up to the train be x.

Then,

The distance traveled by car in times t is,

[tex]\rm Speed = \dfrac{Distance}{Time}\\\\Distance = Speed \times Time\\\\ x = 40 \times t\\\\x = 60t[/tex]

And car travels toward the train from the same starting point leaving 2 hours later than the train.

Then,

The distance traveled by train in time (t+2) is,

[tex]\rm Speed = \dfrac{Distance}{Time}\\\\Distance = Speed \times Time\\\\ x = 40 \times( t+2)\\\\x = 40(t+2)[/tex]

Substitute the value of x in equation 2 from equation 1,

[tex]\rm x = 40(t+2)\\\\60t=40t+80\\\\60t-40t=80\\\\20t=80\\\\t = \dfrac{80}{20}\\\\t = 4[/tex]

Therefore,

The distance traveled by car has to travel to catch up to the train is,

[tex]\rm x = 60t\\\\x = 60\times 4\\\\x = 240 \ miles[/tex]

Hence, The distance traveled by car has to travel to catch up to the train is 240 miles.

The exact solutions of the equation 2sec^2x-tan^4x=-1 are x = 2nπ and x = (2n+1)π/2 for integer values of n.

The given equation is 2sec^2x-tan^4x=-1.

Let's simplify the equation:

2(1/cos^2x)-(tan^2x)^2 = -1

2/cos^2x - tan^4x = -1

Now, substituting sec^2x = 1/cos^2x and tan^2x = (sinx/cosx)^2, we get:

2(1/cos^2x)-((sinx/cosx)^2)^2 = -1

2/cos^2x - sin^4x/cos^4x = -1

Now, let's substitute sin^2x = 1 - cos^2x:

2/cos^2x - (1-cos^2x)^2/cos^4x = -1

Now, solving for cos^2x:

2/cos^2x - (1-2cos^2x+cos^4x) = -1

2 - 2cos^2x + cos^4x - cos^2x = -cos^2x

cos^4x - 3cos^2x + 2 = 0

Now, we can solve for cos^2x by factoring the quadratic equation:

(cos^2x - 2)(cos^2x - 1) = 0

cos^2x = 2 or cos^2x = 1

Since the range of cos^2x is [0,1], we can discard the solution cos^2x = 2.

Therefore, cos^2x = 1.

Which means, cosx = ±1.

Since the required range is [0,2π], we can take two solutions:

cosx = 1, implies x = 2nπ, where n is an integer.

cosx = -1, implies x = (2n+1)π/2, where n is an integer.

Hence, the exact solutions of the equation 2sec^2x-tan^4x=-1 are x = 2nπ and x = (2n+1)π/2 for integer values of n.

The probability of independent events A, B, and C all occurring together is found by multiplying their individual probabilities: P(A AND B AND C) = P(A) × P(B) × P(C) = 0.090528.

Explanation:

The question involves calculating the probability of all three independent events happening simultaneously. To find the combined probability of independent events A, B, and C occurring at the same time, we use the multiplication rule of probability.

This rule states that if the events are independent, the probability of all events occurring is the product of their individual probabilities.

Here are the probabilities for each event:

Probability of event A (P(A)) = 0.43

Probability of event B (P(B)) = 0.32

Probability of event C (P(C)) = 0.66

The probability of events A, B, and C all occurring together is:

P(A AND B AND C) = P(A) × P(B) × P(C) = (0.43) × (0.32) × (0.66) = 0.090528
